A systems administrator must ensure confidential company information is not leaked to competitors. Which of the following services will BEST accomplish this goal?

• A. CASB
• B. IDS
• C. FIM
• D. EDR
• E. DLP

Answer: E

Explanation:
DLP (Data Loss Prevention) is a service that prevents the unauthorized or accidental disclosure of confidential or sensitive data, such as company information, intellectual property, customer data, or personal information. DLP can monitor, detect, and block the data in motion (such as email, web, or network traffic), data at rest (such as files, databases, or cloud storage), or data in use (such as endpoints, applications, or clipboard). DLP can help a systems administrator to ensure confidential company information is not leaked to competitors by applying policies and rules that define what data is considered confidential, who can access it, how it can be used, and what actions to take if a violation occurs. For example, DLP can encrypt, quarantine, delete, or alert the administrator if confidential data is being copied, transferred, or shared outside the organization.

SSO can improve user experience and security, but it may also introduce performance issues if not configured properly. To troubleshoot the issue, the administrator should perform a packet capture during authentication to analyze the network traffic and identify any delays or errors in the SSO process. The administrator should also validate the load-balancing configuration to ensure that the SSO requests are distributed evenly and efficiently among the available servers or instances. The administrator should also analyze the network throughput of the load balancer to check if there is any congestion or bottleneck that may affect the SSO performance.

NEW QUESTION 14

A large pharmaceutical company needs to ensure it is in compliance with the following requirements:
• An application must run on its own virtual machine.
• The hardware the application is hosted on does not change. Which of the following will BEST ensure compliance?

• A. Containers
• B. A firewall
• C. Affinity rules
• D. Load balancers

Answer: C

Explanation:
According to the Virtual Machine Affinity and Anti-Affinity - VMware Docs1, affinity and anti- affinity rules allow you to spread a group of virtual machines across different ESXi hosts or keep a group of virtual machines on a particular ESXi host. An affinity rule places a group of virtual machines on a specific host so that you can easily audit the usage of those virtual machines.
Containers are “a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another” 2. Containers can run on any virtual machine or physical server, and they can be moved between different hosts without affecting the application functionality.
A firewall is “a device or software that monitors and controls the incoming and outgoing network traffic based on predefined rules” 3. A firewall can help protect a cloud environment from unauthorized access and malicious attacks, but it does not affect the placement of virtual machines on hosts.
Load balancers are “devices or software that distribute network or application traffic across
a number of servers” . Load balancers can help improve the performance and availability of a cloud environment by distributing the workload among multiple servers, but they do not affect the placement of virtual machines on hosts.
Based on this information, I think the best answer to your question is C. Affinity rules. Affinity rules can help the pharmaceutical company ensure compliance by placing the application on its own virtual machine and keeping it on the same host. This way, the company can easily audit the usage of the application and avoid any changes in the hardware configuration.

NEW QUESTION 16

A systems administrator is troubleshooting performance issues with a Windows VDI environment. Users have reported that VDI performance is very slow at the start of the workday, but the performance is fine during the rest of the day. Which of the following is the MOST likely cause of the issue? (Choose two.)

• A. Disk I/O limits
• B. Affinity rule
• C. CPU oversubscription
• D. RAM usage
• E. Insufficient GPU resources
• F. License issues

Answer: AC

Explanation:
Disk I/O limits are restrictions or controls that limit the amount of disk input/output operations per second (IOPS) that a VM can perform on a storage device or system. CPU oversubscription is a situation where more CPU resources are allocated to VMs than are physically available on the host or server. Disk I/O limits and CPU oversubscription are most likely to cause VDI performance being very slow at the start of the workday, but fine during the rest of the day, as they can create bottlenecks or contention for disk and CPU resources when multiple users log in or launch their VDI sessions at the same time, resulting in increased latency or reduced throughput for VDI operations.

A systems administrator is using a configuration management tool to perform maintenance tasks in a system. The tool is leveraging the target system's API to perform these maintenance tasks. After a number of features and security updates are applied to the target system, the configuration management tool no longer works as expected. Which of the following is the MOST likely cause of the issue?

• A. The target system's API functionality has been deprecated.
• B. The password for the service account has expired.
• C. The IP addresses of the target system have changed.
• D. The target system has failed after the updates.

Answer: A

Explanation:
The most likely cause of the issue is A. The target system’s API functionality has been deprecated. API deprecation is the process of gracefully discontinuing an API. The process starts by first informing the customers that the API is no longer actively supported even though it will be operational and suggesting them to migrate to an alternate or latest version of the API1. However, sometimes the API functionality may change or be removed without proper notice or documentation, which can break the existing applications that rely on the API. According to the web search results, API deprecation is a common challenge for configuration management tools. Therefore, if the target system’s API functionality has been deprecated after the updates, the configuration management tool may no longer work as expected.
