NEW QUESTION 1

Background Corporate Information
Fabrikam, Inc. is a retailer that sells electronics products on the Internet. The company has a headquarters site and one satellite sales office. You have been hired as the database administrator, and the company wants you to change the architecture of the Fabrikam ecommerce site to optimize performance and reduce downtime while keeping capital expenditures to a minimum. To help with the solution, Fabrikam has decided to use cloud resources as well as on-premise servers.
Physical Locations
All of the corporate executives, product managers, and support staff are stationed at the headquarters office. Half of the sales force works at this location. There is also a satellite sales office. The other half of the sales force works at the satellite office in order to have sales people closer to clients in that area. Only sales people work at the satellite location.
Problem Statement
To be successful, Fabrikam needs a website that is fast and has a high degree of system uptime. The current system operates on a single server and the company is not happy with the single point of failure this presents. The current nightly backups have been failing due to insufficient space on the available drives and manual drive cleanup often needing to happen to get past the errors. Additional space will not be made available for backups on the HQ or satellite servers. During your investigation, you discover that the sales force reports are causing significant contention.
Configuration
Windows Logins
The network administrators have set up Windows groups to make it easier to manage security. Users may belong to more than one group depending on their role. The groups have been set up as shown in the following table:

Server Configuration The IT department has configured two physical servers with Microsoft Windows Server 2012 R2 and SQL Server 2014 Enterprise Edition and one Windows Azure Server. There are two tiers of storage available for use by database files only a fast tier and a slower tier. Currently the data and log files are stored on the fast tier of storage only. If a possible use case exists, management would like to utilize the slower tier storage for data files. The servers are configured as shown in the following table:

Database
Currently all information is stored in a single database called ProdDB, created with the following script:

The Product table is in the Production schema owned by the ProductionStaff Windows group. It is the main table in the system so access to information in the Product table should be as fast as possible. The columns in the Product table are defined as shown in the following table:

The SalesOrderDetail table holds the details about each sale. It is in the Sales schema owned by the SalesStaff Windows group. This table is constantly being updated, inserted into, and read. The columns in the SalesOrderDetail table are defined as shown in the following table:

Database Issues
The current database does not perform well. Additionally, a recent disk problem caused the system to go down, resulting in lost sales revenue. In reviewing the current system, you found that there are no automated maintenance procedures. The database is severely fragmented, and everyone has read and write access.
Requirements Database
The database should be configured to maximize uptime and to ensure that very little data is lost in the event of a server failure. To help with performance, the database needs to be modified so that it can support in-memory data, specifically for the Product table, which the CIO has indicated should be a memoryoptimized table. The auto-update statistics option is set off on this database. Only product managers are allowed to add products or to make changes to the name, description, price, cost, and supplier. The changes are made in an internal database and pushed to the Product table in ProdDB during system maintenance time. Product managers and others working at the headquarters location also should be able to generate reports that include supplier and cost information.
Customer data access
Customers access the company's website to order products, so they must be able to read product information such asname, description, and price from the Product table. When customers place orders, stored procedures calledby the website update product quantityon-hand values. This means the product table is constantly updated at randomtimes.
Customer support data access
Customer support representatives need to be able to view and not update or change product information. Management does not want the customer support representatives to be able to see the product cost or any supplier information.
Sales force data access
Sales people at both the headquarters office and the satellite office must generate reports that read from the Product and SalesOrderDetail tables. No updates or inserts are ever made by sales people. These reports are run at random times and there can be no reporting downtime to refresh the data set except during the monthly maintenance window. The reports that run from the satellite office are process intensive queries with large data sets. Regardless of which office runs a sales force report, the SalesOrderDetail table should only return valid, committed order data; any orders not yet committed should be ignored.
Historical Data
The system should keep historical information about customers who access the site so that sales people can see how frequently customers log in and how long they stay on the site.
The information should be stored in a table called Customer Access. Supporting this requirement should have minimal impact on production website performance.
Backups
The recovery strategy for Fabrikam needs to include the ability to do point in time restores and minimize the risk of data loss by performing transaction log backups every 15 minutes.
Database Maintenance
The company has defined a maintenance window every month when the server can be unavailable. Any maintenance functions that require exclusive access should be accomplished during that window.
Project milestones completed
Revoked all existing read and write access to the database, leaving the schema ownership in place.
Configured an Azure storage container secured with the storage account name MyStorageAccount with the primary access key StorageAccountKey on the cloud file server.
SQL Server 2014 has been configured on the satellite server and is ready for use.
On each database server, the fast storage has been assigned to drive letter F:, and the slow storage has been assigned to drive letter D:.
What should you create in Azure to support the creation of the backups for DB1?

• A. an Azure Content Delivery Network (CDN) endpoint
• B. a Service Bus namespace
• C. a storage account
• D. a cloud service

Answer: C

NEW QUESTION 5

You create an availability group named HaContoso that has replicas named Server01/HA, Server02/HA, and Server03/HA.
Currently, Server01l/HA is the primary replica.
You need to ensure that the following requirements are met:
Backup operations occur on Server02/HA.
If Server02/HA is unavailable, backup operations occur on Server03/HA.
Backup operations do not occur on Server01/HA.
How should you configure HaContoso?

• A. Set the backup preference of HaContoso to Prefer Secondar
• B. Set the backup priority of Server02/HA to20. Set the backup priority of Server03/HA to 10.
• C. Set the backup preference of HaContoso to Secondary onl
• D. Set the backup priority of Server02/HA to20. Set the backup priority of Server03/HA to 10.
• E. Set the backup preference of HaContoso to Secondary onl
• F. Set the backup priority of Server02/HA to10. Set the backup priority of Server03/HA to 20.
• G. set the exclude replica of Server01/HA to tru
• H. Set the backup priority of Server02/HA to 10. Set the backup priority of Server03/HA to 20.

Answer: B

Explanation:
Secondary only: Specifies that backups should never be performed on the primary replica. If the primary replica is the only replica online, the backup should not occur.
Backup Priority (Lowest=1, Highest=100)
Specifies your priority for performing backups on this replica relative to the other replicas in the same availability group. The value is an integer in the range of 0..100. 1 indicates the lowest priority, and 100 indicates the highest priority. If Backup Priority = 1, the availability replica would be chosen for performing backups only if no higher priority availability replicas are currently available.

NEW QUESTION 6

General Overview
You are the Senior Database Administrator (DBA) for a software development company named Leafield Solutions. The company develops software applications custom designed to meet customer requirements.
Requirements Leafield Solutions has been asked by a customer to develop a web-based Enterprise Resource Planning and Management application. The new application will eventually replace a desktop application that the customer is currently using. The current application will remain in use while the users are trained to use the new webbased application.
You need to design the SQL Server and database infrastructure for the web-based application. Databases
You plan to implement databases named Customers, Sales, Products, Current_Inventory, and TempReporting. The Sales database contains a table named OrderTotals and a table named SalesInfo.
A stored procedure named SPUpdateSalesInfo reads data in the OrderTotals table and modifies data in the SalesInfo table.
The stored procedure then reads data in the OrderTotals table a second time and makes further changes to the information in the SalesInfo table.
The Current_Inventory database contains a large table named Inv_Current. The Inv_Current table has a clustered index for the primary key and a nonclustered index. The primary key column uses the identity property.
The data in the Inv_Current table is over 120GB in size. The tables in the Current_Inventory database are accessed by multiple queries in the Sales database.
Another table in the Current_Inventory database contains a self-join with an unlimited number of hierarchies. This table is modified by a stored procedure named SPUpdate2.
An external application named ExternalApp1 will periodically query the Current_Inventory database to generate statistical information. The TempReporting database contains a single table named GenInfo.
A stored procedure named SPUPdateGenInfo combines data from multiple databases and generates millions of rows of data in the GenInfo table.
The GenInfo table is used for reports.
When the information in GenInfo is generated, a reporting process reads data from the Inv_Current table and queries information in the GenInfo table based on that data.
The GenInfo table is deleted after the reporting process completes. The Products database contains tables named ProductNames and ProductTypes.
Current System
The current desktop application uses data stored in a SQL Server 2005 database named DesABCopAppDB. This database will remain online and data from the Current_Inventory database will be copied to it as soon as data is changed in the Current_Inventory database.
SQL Servers
A new SQL Server 2012 instance will be deployed to host the databases for the new system. The databases will be hosted on a Storage Area Network (SAN) that provides highly available storage.
Design Requirements
Your SQL Server infrastructure and database design must meet the following requirements:
Confidential information in the Current_ Inventory database that is accessed by ExternalApp1 must be securely stored.
Direct access to database tables by developers or applications must be denied.
The account used to generate reports must have restrictions on the hours when it is allowed to make a connection.
Deadlocks must be analyzed with the use of Deadlock Graphs.
In the event of a SQL Server failure, the databases must remain available.
Software licensing and database storage costs must be minimized.
Development effort must be minimized.
The Tempdb databases must be monitored for insufficient free space.
Failed authentication requests must be logged.
Every time a new row is added to the ProductTypes table in the Products database, a user defined function that validates the row must be called before the row is added to the table.
When SPUpdateSalesInfo queries data in the OrderTotals table the first time, the same rows must be returned along with any newly added rows when SPUpdateSalesInfo queries data in the OrderTotals table the second time.
You need to configure a synchronization solution to copy data from the Current_Inventory database the DesABCopAppDB database.
What should you configure?

• A. Transactional Replication.
• B. Database Mirroring.
• C. Snapshot Replication.
• D. Incremental Backups

Answer: A

NEW QUESTION 8

Note: This question is part of a series of questions that use the same or similar answer choices. An answer
choice may be correct for more than one question in the series. Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.
A company has several Microsoft SQL Server database in Microsoft Azure.
One database experiences a storage failure, and pages that store critical database metadata are corrupted. You need to perform an offline restore of the database’s pages.
Which option should you use first?

• A. backup compression
• B. backup encryption
• C. file snapshot backup
• D. mirrored backup media sets
• E. SQL Server backup to URL
• F. SQL Server Managed Backup to Azure
• G. tail-log backup
• H. back up and truncate the transaction log

Answer: G

Explanation:
An unbroken chain of log backups must be available, up to the current log file, and they must all be applied to bring the page up to date with the current log file.
A tail-log backup captures any log records that have not yet been backed up (the tail of the log) to prevent work loss and to keep the log chain intact. Before you can recover a SQL Server database to its latest point in time, you must back up the tail of its transaction log. The tail-log backup will be the last backup of interest in the recovery plan for the database.
Note: The goal of a page restore is to restore one or more damaged pages without restoring the whole database. Typically, pages that are candidates for restore have been marked as "suspect" because of an error that is encountered when accessing the page.

NEW QUESTION 10

You deploy a database by using SQL Server 2014. The database contains a table named Table1.
You need to recommend a solution to track all of the deletions executed on Table1. The solution must minimize the amount of custom code required.
What should you recommend?

• A. Change data capture
• B. Statistics
• C. A trigger
• D. Master Data Services

Answer: A

Explanation:
Change data capture is designed to capture insert, update, and delete activity applied to SQL Server tables, and to make the details of the changes available in an easily consumed relational format. The change tables used by change data capture contain columns that mirror the column structure of a tracked source table, along with the metadata needed to understand the changes that have occurred.

You manage a database that uses the FULL recovery model and has a 60-minute recovery point objective (RPO). Full database backups are performed at 23:00 Monday through Friday.
Each full database backup takes 6 hours to complete. Approximately 5% of the data changes each weekday. Backups must be performed as often as possible to reduce the number of files needed either a full recovery to
any given time. You must minimize the duration of the backup tasks that are performed between 04:00 and
23:00.
You need to reconfigure backups.
Which time slot or schedule should you use for each backup type?

• A. Mastered
• B. Not Mastered

Answer: A

NEW QUESTION 13

You have the following Microsoft SQL Server instances:

You have a database named DB1 that is hosted on SQL1.
Users in the branch office must be able to access DB1 from SQL3.
You need to configure an AlwaysOn Availability Group and limit latency on the secondary server. Which settings should you configure?

• A. FAILOVER_MODE = AUTOMATIC
• B. AVAILABILITY MODE = SYNCHRONOUS_COMMIT
• C. FAILOVER_MODE = MANUAL
• D. AVAILABILITY MODE = ASYNCHRONOUS_COMMIT

Answer: D

Explanation:
Asynchronous-commit mode is a disaster-recovery solution that works well when the availability replicas are distributed over considerable distances. If every secondary replica is running under asynchronous-commit mode, the primary replica does not wait for any of the secondary replicas to harden the log. Rather, immediately after writing the log record to the local log file, the primary replica sends the transaction confirmation to the client. The primary replica runs with minimum transaction latency in relation to a secondary replica that is configured for asynchronous-commit mode. If the current primary is configured for asynchronous commit availability mode, it will commit transactions asynchronously for all secondary replicas regardless of their individual availability mode settings.

NEW QUESTION 14

You have a database named DB1. You observe issues with indexes and other consistency issues.
You need to identify and repair all physical database problems while minimizing data loss and database downtime.
Which four Transact SQL statements should you use to develop the solution?

Answer: A

Explanation:

NEW QUESTION 15

You administer a SQL Server 2014 instance.
Users report that the SQL Server has seemed slow today.
A large database was being restored for much of the day, which could be causing issues. You want to write a query of the system views that will report the following:
Number of users that have a connection to the server
Whether a user's connection is active
Whether any connections are blocked
What queries are being executed
Whether the database restore is still executing and, if it is, what percentage of the restore is complete. Which system objects should you use in your query to best achieve this task?

• A. sys.dm_exec_requests, sys.dm_exec_sessions, sys.objects
• B. sys.dm_exec_sessions, sys.dm_exec_query_stats, sys.dm_exec_query_text,sys.objects
• C. sys.sysprocesses, sys.dm_exec_query_text, sys.objects
• D. sys.dm_exec_requests, sys.dm_exec_sessions, sys.dm_exec_query_text

Answer: D

Explanation:
- sys.dm_exec_requests
Returns information about each request that is executing within SQL Server.
- sys.dm_exec_sessions
Returns one row per authenticated session on SQL Server. sys.dm_exec_sessions is a serverscope view that shows information about all active user connections and internal tasks. This information includes client version, client program name, client login time, login user, current session setting, and more.
- sys.dm_exec_query_text
Returns the text of the SQL batch that is identified by the specified sql_handle.

NEW QUESTION 16

You plan to deploy a database to SQL Azure. You are designing two stored procedures named USP_1 and USP_2 that have the following requirements:
Prevent data read by USP_1 from being modified by other active processes.
Allow USP_2 to perform dirty reads.
You need to recommend the isolation level for the stored procedures. The solution must maximize concurrency.
Which isolation levels should you recommend? To answer, drag the appropriate isolation level to the correct stored procedure in the answer area.

• A. Mastered
• B. Not Mastered

Answer: A

Explanation:
SP1 – repeatable read; SP2 – read uncommited Note:
- SP1: repeatable read a repeatable read scan retains locks on every row it touches until the end of the transaction. Even rows that do not qualify for the query result remain locked. These locks ensure that the rows touched by the query cannot be updated or deleted by a concurrent session until the current transaction completes (whether it is committed or rolled back).
- SP2: read uncommitted permits repeatable reads

NEW QUESTION 17

You are troubleshooting an application that runs a query. The application frequently causes deadlocks. You need to identify which transaction causes the deadlock.
What should you do? More than one answer choice may achieve the goal. Select the BEST answer.

• A. Query the sys.dm_exec_requests dynamic management view.
• B. Create a trace in SQL Server Profiler that contains the Deadlock graph event.
• C. Query the sys.dm_exec_sessions dynamic management view.
• D. Create an extended events session to capture deadlock information.

Answer: D

Explanation:
Troubleshooting deadlocks
You have been receiving reports from users indicating that certain applications are returning deadlock errors. To maximize the effectiveness of troubleshooting these problems, you decide to focus on the deadlocks that are hit most frequently. You create an Extended Events session that:
Configures deadlock event tracking for the session.
Specifies a target that aggregates based on an identifier for the deadlock.
You run the Extended Events session, and after additional deadlocks are reported you are able to obtain aggregated deadlock information, along with the complete XML deadlock graph for each source. Using this information, you are able to pin point the most common deadlocks and start working on a solution.

NEW QUESTION 18

You have an SQL Server 2014 server. You plan to create four stored procedures that will use transactions. The stored procedures will be configured as shown in the following table.

You need to recommend an isolation level for each stored procedure. The solution must support the concurrency strategy of each stored procedure and must minimize locks.
What should you recommend?
To answer, drag the appropriate isolation levels to the correct stored procedures. Each isolation level may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

• A. Mastered
• B. Not Mastered

Answer: A

Explanation:
SP1 – SNAPSHOT, SP2 – REPEATABLE READ, SP3 – READ COMMITTED, SP4 - SERIALIZABLE

• A. Evict the node from Failover Cluster Manager.
• B. Run the Remove-cluster Windows PowterShell cmdlet.
• C. Run the Remove-ClusterResource Windows PowerShell cmdlet.
• D. Remove the shared storage from Failover Cluster Manager.

Answer: A

Explanation:
Recover from an irreparable failure
Use the following steps to recover from an irreparable failure. The failure could be caused, for example, by the failure of a disk controller or the operating system. In this case, failure is caused by hardware failure in Node 1 of a two-node cluster.
After Node 1 fails, the SQL Server FCI fails over to Node 2.
Evict Node 1 from the FCI. To do this, from Node 2, open the Failover Cluster Manager snap-in, right-click Node1, click Move Actions, and then click Evict Node.
Verify that Node 1 has been evicted from the cluster definition.
Install new hardware to replace the failed hardware in Node 1.
Using the Failover Cluster Manager snap-in, add Node 1 to the existing cluster. For more information, see Before Installing Failover Clustering.
Ensure that the administrator accounts are the same on all cluster nodes.
Run SQL Server Setup to add Node 1 to the FCI. For more information, see Add or Remove Nodes in a SQL Server Failover Cluster (Setup).

NEW QUESTION 27

Overview
Application Overview
Contoso, Ltd., is the developer of an enterprise resource planning (ERP) application.
Contoso is designing a new version of the ERP application. The previous version of the ERP application used SQL Server 2008 R2.
The new version will use SQL Server 2014.
The ERP application relies on an import process to load supplier data. The import process updates thousands of rows simultaneously, requires exclusive access to the database, and runs daily.
You receive several support calls reporting unexpected behavior in the ERP application. After analyzing the calls, you conclude that users made changes directly to the tables in the database.
Tables
The current database schema contains a table named OrderDetails.
The OrderDetails table contains information about the items sold for each purchase order. OrderDetails stores the product ID, quantities, and discounts applied to each product in a purchase order.
The product price is stored in a table named Products. The Products table was defined by using the SQL_Latin1_General_CP1_CI_AS collation.
A column named ProductName was created by using the varchar data type. The database contains a table named Orders.
Orders contains all of the purchase orders from the last 12 months. Purchase orders that are older than 12 months are stored in a table named OrdersOld.
The previous version of the ERP application relied on table-level security. Stored Procedures
The current version of the database contains stored procedures that change two tables. The following shows the relevant portions of the two stored procedures:

Customer Problems Installation Issues
The current version of the ERP application requires that several SQL Server logins be set up to function correctly. Most customers set up the ERP application in multiple locations and must create logins multiple times.
Index Fragmentation Issues
Customers discover that clustered indexes often are fragmented. To resolve this issue, the customers defragment the indexes more frequently. All of the tables affected by fragmentation have the following columns that are used as the clustered index key:

Backup Issues
Customers who have large amounts of historical purchase order data report that backup time is unacceptable. Search Issues
Users report that when they search product names, the search results exclude product names that contain accents, unless the search string includes the accent.
Missing Data Issues
Customers report that when they make a price change in the Products table, they cannot retrieve the price that the item was sold for in previous orders.
Query Performance Issues
Customers report that query performance degrades very quickly. Additionally, the customers report that users cannot run queries when SQL Server runs maintenance tasks. Import Issues During the monthly import process, database administrators receive many supports call from users who report that they cannot access the supplier data. The database administrators want to reduce the amount of time required to import the data.
Design Requirements
File Storage Requirements
The ERP database stores scanned documents that are larger than 2 MB. These files must only be accessed through the ERP application. File access must have the best possible read and write performance.
Data Recovery Requirements
If the import process fails, the database must be returned to its prior state immediately. Security Requirements
You must provide users with the ability to execute functions within the ERP application, without having direct access to the underlying tables.
Concurrency Requirements
You must reduce the likelihood of deadlocks occurring when Sales.Prod and Sales.Proc2 execute. You need to recommend a solution that resolves the missing data issue.
The solution must minimize the amount of development effort. What should you recommend?

• A. Denormalize the Products table.
• B. Denormalize the OrderDetails table.
• C. Normalize the OrderDetails table.
• D. Normalize the Products table.

Answer: D

Explanation:
- Scenario:
- Missing Data Issues
Customers report that when they make a price change in the Products table, they cannot retrieve the price that
the item was sold for in previous orders.
- The current database schema contains a table named OrderDetails. The OrderDetails table contains information about the items sold for each purchase order. OrderDetails stores the product ID, quantities, and discounts applied to each product in a purchase order.
The product price is stored in a table named Products.

NEW QUESTION 29

You plan to deploy SQL Server 2012. You must create two tables named Table 1 and Table 2 that will have the following specifications:
Table1 will contain a date column named Column1 that will contain a null value approximately 80 percent of the time.
Table2 will contain a column named Column2 that is the product of two other columns in Table2. Both Table1 and Table2 will contain more than 1 million rows.
You need to recommend which options must be defined for the columns. The solution must minimize the storage requirements for the tables.
Which options should you recommend? To answer, drag the appropriate options to the correct column in the answer area.

• A. Mastered
• B. Not Mastered

Answer: A

Explanation:
Column1 – Sparse; Column2 - Computed
- Sparse columns are ordinary columns that have an optimized storage for null values. Sparse columns reduce the space requirements for null values at the cost of more overhead to retrieve nonnull values. Consider using sparse columns when the space saved is at least 20 percent to 40 percent.
- A Persisted column would be faster to retrieve.
- A computed column is computed from an expression that can use other columns in the same table. The expression can be a noncomputed column name, constant, function, and any combination of these connected by one or more operators. Unless otherwise specified, computed columns are virtual columns that are not physically stored in the table. Their values are recalculated every time they are referenced in a query. The Database Engine uses the PERSISTED keyword in the CREATE TABLE and ALTER TABLE statements to physically store computed columns in the table. Their values are updated when any columns that are part of their calculation change.
