CompTIA CompTIA Certifications CV0-003 Questions & Answers

• Question 241:

  The human resources department was charged for a cloud service that belongs to another department. All other cloud costs seem to be correct. Which of the following is the MOST likely cause for this error?

  A. Misconfigured templates

  B. Misconfigured chargeback

  C. Incorrect security groups

  D. Misconfigured tags

  Correct Answer: B

  The most likely cause for this error is misconfigured chargeback (Option B). Chargeback is a process by which the costs of using a service are allocated to the departments or individuals that are using that service. If the chargeback is misconfigured, it could result in costs being incorrectly allocated to the wrong department. This would explain why the human resources department is being charged for a service that belongs to another department, while all other cloud costs seem to be correct.

• Question 242:

  A cloud administrator is building a new VM for machine-learning training. The developer requesting the VM has stated that the machine will need a full GPU dedicated to it.

  Which of the following configuration options would BEST meet this requirement?

  A. Virtual GPU

  B. External GPU

  C. Passthrough GPU

  D. Shared GPU

  Correct Answer: C

  Passthrough GPU is a configuration option that allows a VM to access a physical GPU directly without any virtualization layer or sharing mechanism.

• Question 243:

  A cloud administrator recently deployed an update to the network drivers of several servers. Following the update, one of the servers no longer responds to remote login requests. The cloud administrator investigates the issue and gathers the following information:

  1.

  The cloud management console shows the VM is running and the CPU and memory utilization is at or near 0%.

  2.

  The cloud management console does not show an IP address for that server. A DNS lookup shows the hostname resolves to an IP address.

  3.

  The server is a member of the same security group as the others.

  4.

  The cloud administrator is able to log in remotely to the other servers without issue.

  Which of the following is the MOST likely cause of the server being unavailable?

  A. The network driver updates did not apply successfully, and the interface is in a down state.

  B. The ACL policy for the server was updated as part of the server reboot, preventing login access.

  C. The server was assigned a new IP address, and DNS entry for the server name was not updated.

  D. The update caused an increase in the output to the logs, and the server is too busy to respond.

  Correct Answer: A

• Question 244:

  A cloud engineer is responsible for managing two cloud environments from different MSPs. The security department would like to inspect all traffic from the two cloud environments.

  Which of the following network topology solutions should the cloud engineer implement to reduce long-term maintenance?

  A. Chain

  B. Star

  C. Mesh

  D. Hub and spoke

  Correct Answer: D

  Hub and spoke is a type of network topology that consists of a central node or device (hub) that connects to multiple peripheral nodes or devices (spokes). Hub and spoke can help reduce long-term maintenance for managing two cloud environments from different MSPs, as it can simplify and centralize the network configuration and management by using the hub as a single point of contact and control for the spokes. Hub and spoke can also improve network performance and security, as it can reduce latency, bandwidth consumption, and network congestion by routing traffic through the hub.

• Question 245:

  A system administrator is migrating a bare-metal server to the cloud. Which of the following types of migration should the systems administrator perform to accomplish this task?

  A. V2V

  B. V2P

  C. P2P

  D. P2V

  Correct Answer: D

  P2V (Physical to Virtual) is a type of migration that converts a physical server into a virtual machine (VM). P2V migration can help to move a bare-metal server to the cloud by creating an image of its disk and configuration and uploading it to a cloud platform that supports VM creation from custom images.

• Question 246:

  A company needs a solution to find content in images. Which of the following technologies, when used in conjunction with cloud services, would facilitate the BEST solution?

  A. Internet of Things

  B. Digital transformation

  C. Artificial intelligence

  D. DNS over TLS

  Correct Answer: C

  Artificial intelligence (AI) is the technology that, when used in conjunction with cloud services, would facilitate the best solution for finding content in images. AI is a branch of computer science that aims to create machines or systems that can perform tasks that normally require human intelligence, such as reasoning, learning, decision making, etc. AI can be used to analyze images and extract information such as objects, faces, text, emotions, etc., using techniques such as computer vision, machine learning, natural language processing, etc. AI can help to find content in images faster, more accurately, and more efficiently than manual methods.

• Question 247:

  A software development manager is looking for a solution that will allow a team of developers to work in isolated environments that can be spun up and torn down quickly.

  Which of the following is the MOST appropriate solution?

  A. Containers

  B. File subscriptions

  C. Ballooning

  D. Software-defined storage

  Correct Answer: A

  Containers are isolated environments that can run applications and their dependencies without interfering with other processes or systems. Containers are lightweight, portable, and scalable, which makes them ideal for development and testing purposes. Containers can be spun up and torn down quickly using tools such as Docker, Kubernetes, etc.

• Question 248:

  A cloud administrator is building a new VM for a network security appliance. The security appliance installer says the CPU clock speed does not meet the requirements.

  Which of the following will MOST likely solve the issue?

  A. Move the VM to a host with a faster CPU

  B. Add more vCPUs to the VM

  C. Enable CPU masking on the VM

  D. Enable hyperthreading on the virtual host

  Correct Answer: A

  Moving the VM to a host with a faster CPU is the best way to solve the issue of the security appliance installer saying the CPU clock speed does not meet the requirements when building a new VM for a network security appliance. Moving the VM to a host with a faster CPU can ensure that the VM meets the minimum CPU clock speed requirement for the security appliance, as it can use the physical CPU resources of the host. Moving the VM to a host with a faster CPU can also improve the performance and reliability of the security appliance, as it can reduce latency, contention, and overhead.

• Question 249:

  A database analyst reports it takes two hours to perform a scheduled job after onboarding 10,000 new users to the system. The analyst made no changes to the scheduled job before or after onboarding the users. The database is hosted in an IaaS instance on a cloud provider.

  Which of the following should the cloud administrator evaluate to troubleshoot the performance of the job?

  A. The laaS compute configurations, the capacity trend analysis reports, and the storage IOPS

  B. The hypervisor logs, the memory utilization of the hypervisor host, and the network throughput of the hypervisor

  C. The scheduled job logs for successes and failures, the time taken to execute the job, and the job schedule

  D. Migrating from laaS to on premises, the network traffic between on-premises users and the laaS instance, and the CPU utilization of the hypervisor host

  Correct Answer: A

  To troubleshoot the performance of a scheduled job that takes two hours to run after onboarding 10,000 new users to a cloud-based system, the administrator should evaluate the IaaS compute configurations, the capacity trend analysis reports, and the storage IOPS. These factors can affect the performance of a database job in an IaaS instance on a cloud provider. The IaaS compute configurations include the CPU, memory, and network resources assigned to the instance. The capacity trend analysis reports show the historical and projected usage and demand of the resources. The storage IOPS (Input/Output Operations Per Second) measure the speed and performance of the disk storage. The administrator should check if these factors are sufficient, optimal, or need to be adjusted to improve the performance of the job.

• Question 250:

  A systems administrator wants the VMs on the hypervisor to share CPU resources on the same core when feasible.

  Which of the following will BEST achieve this goal?

  A. Configure CPU passthrough

  B. Oversubscribe CPU resources

  C. Switch from a Type 1 to a Type 2 hypervisor

  D. Increase instructions per cycle

  E. Enable simultaneous multithreading

  Correct Answer: E

  Simultaneous multithreading (SMT) is a type of CPU technology that allows multiple threads to run concurrently on a single CPU core. Enabling SMT can help achieve the goal of having the VMs on the hypervisor share CPU resources on the same core when feasible, as it can increase the CPU utilization and efficiency by executing more instructions per cycle and reducing idle time or wasted cycles. Enabling SMT can also improve performance and throughput, as it can speed up processing and handle increased workload or demand.
