NEW QUESTION 2

A company would like to move all its on-premises platforms to the cloud. The company has enough skilled Linux and web-server engineers but only a couple of skilled database administrators. It also has little expertise in managing email services. Which of the following solutions would BEST match the skill sets of available personnel?

• A. Run the web servers in PaaS, and run the databases and email in SaaS.
• B. Run the web servers, databases, and email in SaaS.
• C. Run the web servers in laaS, the databases in PaaS, and the email in SaaS.
• D. Run the web servers, databases, and email in laaS.

Answer: C

Explanation:
To answer this question, we need to understand the different types of cloud computing models and how they suit the skill sets of the available personnel. According to Google Cloud, there are three main models for cloud computing: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Each model provides different levels of control, flexibility, and management over the cloud resources and services1.
✑ IaaS: This model provides access to networking features, computers (virtual or on dedicated hardware), and data storage space. It gives the highest level of flexibility and management control over the IT resources and is most similar to existing IT resources that many IT departments and developers are familiar with2.
✑ PaaS: This model provides a complete cloud platform for developing, running, and managing applications without the cost, complexity, and inflexibility of building and maintaining the underlying infrastructure. It removes the need for organizations to manage the hardware and operating systems and allows them to focus on the deployment and management of their applications2.
✑ SaaS: This model provides a completed product that is run and managed by the service provider. It does not require any installation, maintenance, or configuration by the customers. It is typically used for end-user applications that are accessed through a web browser or a mobile app2.
Based on these definitions, we can evaluate each option:
✑ Option A: Run the web servers in PaaS, and run the databases and email in SaaS. This option is not the best match for the skill sets of the available personnel because it does not leverage their expertise in Linux and web-server engineering. Running the web servers in PaaS means that they will have less control and customization over the web server environment and will have to rely on the service provider’s platform features. Running the databases and email in SaaS means that they will not need any database administration or email management skills, but they will also have less flexibility and security over their data and communication.
✑ Option B: Run the web servers, databases, and email in SaaS. This option is not a good match for the skill sets of the available personnel because it does not utilize their skills at all. Running everything in SaaS means that they will have no control or responsibility over any aspect of their cloud environment and will have to depend entirely on the service provider’s products. This option may be suitable for some small businesses or non-technical users who do not have any IT skills or resources, but not for a company that has skilled Linux and web-server engineers.
✑ Option C: Run the web servers in IaaS, the databases in PaaS, and the email in SaaS. This option is the best match for the skill sets of the available personnel because it balances their strengths and weaknesses. Running the web servers in IaaS means that they can use their Linux and web-server engineering skills to configure, manage, and optimize their web server infrastructure according to their needs. Running the databases in PaaS means that they can leverage the service provider’s platform features to simplify their database development and administration tasks without having to worry about the underlying hardware and operating systems. Running the email in SaaS means that they can outsource their email services to a reliable and secure service provider without having to invest in or manage their own email infrastructure.
✑ Option D: Run the web servers, databases, and email in IaaS. This option is not a good match for the skill sets of the available personnel because it puts too much burden on them. Running everything in IaaS means that they will have to handle all aspects of their cloud environment, including networking, computing, storage, security, backup, scaling, patching, etc. This option may be suitable for some large enterprises or highly technical users who have full control and customization over their cloud environment, but not for a company that has only a couple of skilled database administrators and little expertise in managing email services.
Therefore, option C is the correct answer.

• D. iSCSI storage

Answer: B

Explanation:
Thin provisioning is the technique that ensures disk space is not allocated to the VM until it is needed. Thin provisioning is a storage allocation method that assigns disk space to a VM on demand, rather than in advance. Thin provisioning can improve storage utilization and efficiency by avoiding overprovisioning and wasting disk space. Thin provisioning can also allow for more flexibility and scalability of storage resources.

NEW QUESTION 4

A VDI administrator is enhancing the existing environment with a feature to allow users to connect devices to virtual workstations. Which of the following types of devices are most likely to be allowed in the upgrade? (Select two).

• A. Display monitors
• B. USB devices
• C. SATA devices
• D. PCIe devices
• E. PCI devices
• F. Printers

Answer: BF

Explanation:
B. USB devices and F. Printers are most likely to be allowed in the upgrade. USB devices are common peripherals that users may want to connect to their virtual workstations, such as flash drives, keyboards, mice, webcams, etc. Printers are also useful devices that users may need to print documents from their virtual desktops. VDI software can support USB redirection and printer redirection to enable these devices to work with virtual workstations12.
Display monitors, SATA devices, PCIe devices, and PCI devices are less likely to be allowed in the upgrade, as they are either part of the physical hardware of the end device or the server, or they require direct access to the host system. VDI software typically does not support these types of devices, as they are not compatible with the virtualization layer or the remote display protocol34.

NEW QUESTION 15

A systems administrator is setting up a backup solution to follow the 3-2-1 policy. Currently, the solution is set to back up from the servers to an on-site storage server. Which of the following should the administrator configure to comply with the 3-2-1 policy?

• A. Weekly lull backups, with daily incremental backups
• B. A second on-site storage server for backups
• C. Storage snapshots
• D. An off-site storage server for backups

Answer: D

Explanation:
The 3-2-1 backup policy states that there should be three copies of data, stored on two different media, with one copy being off-site. The current backup solution only has one copy of data on one media (the on-site storage server). To comply with the 3- 2-1 policy, the systems administrator should configure an off-site storage server for backups, which will provide another copy of data on a different media and location. Reference: CompTIA Cloud+ Certification Exam Objectives, Domain 3.0 Maintenance, Objective 3.2 Given a scenario, implement backup, restore, disaster recovery and business continuity measures.

NEW QUESTION 16

An organization deployed an application using a cloud provider's internal managed certificates. Developers are unable to retrieve data when calling the API from any machine.
The following error message is in the log:
12-04-2023-10:05:25, SSL Negotiation Error 12-04-2023-10:05:28,Invalid Certificate
12-04-2023-10:05:29, TLS Handshake Failed 12-04-2023-10:05:30,Connection Closed
Which of the following is the most likely cause of the error?

• A. TLS version
• B. Insecure cipher
• C. Self-signed certificate
• D. Root trust

Answer: D

Explanation:
The error message indicates that the SSL/TLS handshake failed due to an invalid certificate. This means that the client machine does not trust the certificate authority (CA) that issued the certificate for the cloud provider’s API. A self-signed certificate or an insecure cipher would not cause this error, as they would be detected during the certificate validation process. The TLS version is not relevant, as the error occurs before the protocol negotiation. The most likely cause of the error is that the client machine does not have the root CA certificate installed in its trust store, or that the cloud provider’s certificate chain is incomplete or broken. To fix the error, the client machine needs to install the root CA certificate or the cloud provider needs to fix its certificate chain.
