CompTIA CompTIA Certifications CV0-004 Questions & Answers

• Question 221:

  An organization is hosting a seminar with eight individuals who need to connect to their own dedicated VM. The technician used the following VM configurations:

  IP address: DHCP NIC: 1Gbps Network: 10.1.10.0/29

  Several users are unable to access their VMs. Which of the following best describes the reason?

  A. Not enough addresses are available.

  B. The routes are misconfigured.

  C. Too much traffic is on the network.

  D. DHCP is not working correctly on the VM.

  Correct Answer: A

  The network is configured with a subnet of /29, which provides only 6 usable IP addresses after accounting for the network and broadcast addresses. With eight individuals needing to connect to their own dedicated VMs, there are not enough IP addresses available to assign to each VM, leading to several users being unable to access their VMs. This issue is not related to misconfigured routes, network traffic, or DHCP functionality, but rather the limited number of IP addresses available in the given subnet.

• Question 222:

  A company wants to optimize cloud resources and lower the overhead caused by managing multiple operating systems. Which of the following compute resources would be best to help to achieve this goal?

  A. VM

  B. Containers

  C. Remote desktops

  D. Bare-metal servers

  Correct Answer: B

  Containers are the best compute resources to optimize cloud resources and lower the overhead caused by managing multiple operating systems. Containers encapsulate applications and their dependencies into a single executable package, running on a shared OS kernel, which reduces the need for separate operating systems for each application and simplifies resource management.References: CompTIA Cloud+ materials discuss management and technical operations in cloud environments, including the use of containers to improve resource utilization and operational efficiency by minimizing the overhead associated with traditional VMs.

• Question 223:

  A company that has several branches worldwide needs to facilitate full access to a specific cloud resource to a branch in Spain. Other branches will have only read access. Which of the following is the best way to grant access to the branch in Spain?

  A. Set up MFA for the users working at the branch.

  B. Create a network security group with required permissions for users in Spain.

  C. Apply a rule on the WAF to allow only users in Spain access to the resource.

  D. Implement an IPS/IDS to detect unauthorized users.

  Correct Answer: B

  The best way to grant full access to a specific cloud resource to a branch in Spain, while other branches have only read access, is to create a network security group with the required permissions. This group can be configured to allow full

  access to users within the branch's IP range while restricting others to read-only access.

• Question 224:

  A company needs to deploy its own code directly in the cloud without provisioning additional infrastructure. Which of the following is the best cloud service model for the company to use?

  A. PaaS

  B. SaaS

  C. laaS

  D. XaaS

  Correct Answer: A

  Platform as a Service (PaaS) is the best cloud service model for deploying code directly in the cloud without provisioning additional infrastructure. PaaS provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure.References: The PaaS model and its benefits for application deployment are covered under the Cloud Concepts domain in the CompTIA Cloud+ certification.

• Question 225:

  Which of the following is the most cost-effective way to store data that is infrequently accessed?

  A. Cold site

  B. Hot site

  C. Off-site

  D. Warm site

  Correct Answer: C

  The most cost-effective way to store data that is infrequently accessed is typically an off-site storage service, often referred to as cold or archival storage. This type of storage is designed for data that is rarely accessed, providing lower storage costs.References: Data storage solutions and their cost implications, including off-site (cold or archival) storage for infrequently accessed data, are part of the cloud storage options discussed in CompTIA Cloud+.

• Question 226:

  An e-commerce store is preparing for an annual holiday sale. Previously, this sale has increased the number of transactions between two and ten times the normal level of transactions. A cloud administrator wants to implement a process to scale the web server seamlessly. The goal is to automate changes only when necessary and with minimal cost.

  Which of the following scaling approaches should the administrator use?

  A. Scale horizontally with additional web servers to provide redundancy.

  B. Allow the load to trigger adjustments to the resources.

  C. When traffic increases, adjust the resources using the cloud portal.

  D. Schedule the environment to scale resources before the sale begins.

  Correct Answer: B

  To seamlessly scale the web server for an e-commerce store during an annual sale, it's best to allow the load to trigger adjustments to the resources. This approach uses autoscaling to automatically adjust the number of active servers based on the current load, ensuring an automated change that is cost-effective.

• Question 227:

  Which of the following migration types is best to use when migrating a highly available application, which is normally hosted on a local VM cluster, for usage with an external user population?

  A. Cloud to on-premises

  B. Cloud to cloud

  C. On-premises to cloud

  D. On-premises to on-premises

  Correct Answer: C

  When migrating a highly available application normally hosted on a local VM cluster for usage with an external user population, the best migration type would be on- premises to cloud. This allows the application to leverage the cloud's scalability and reach, providing better access to the external users. References: CompTIA Cloud+ Study Guide (V0-004) - Chapter on Cloud Migration

• Question 228:

  An administrator is creating a cron job that shuts down the virtual machines at night to save on costs. Which of the following is the best way to achieve this task?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: C

  Option C is the correct script for shutting down virtual machines that are currently running. It iterates through a list of VMs, checks if the status of each VM is 'running', and if so, proceeds to shut down the VM. The script then prints a message stating that the VM has been stopped. This approach ensures that only VMs that are actively running are targeted for shutdown, optimizing resource utilization and cost savings.

• Question 229:

  Which of the following cloud deployment strategies is best for an organization that wants to run open-source workloads with other organizations that are sharing the cost?

  A. Community

  B. Public

  C. Hybrid

  D. Private

  Correct Answer: A

  A community cloud deployment strategy is best for an organization that wants to run open-source workloads with other organizations while sharing the cost. Community clouds are collaborative efforts where infrastructure is shared between several organizations with common concerns, which could be regulatory, security, or compliance- related.References: The concept of community clouds is discussed in the domain of Cloud Concepts within the CompTIA Cloud+ exam objectives.

• Question 230:

  A company has decided to adopt a microservices architecture for its applications that are deployed to the cloud. Which of the following is a major advantage of this type of architecture?

  A. Increased security

  B. Simplified communication

  C. Reduced server cost

  D. Rapid feature deployment

  Correct Answer: D

  A major advantage of adopting a microservices architecture is rapid feature deployment. Microservices allow for independent development, deployment, and scaling of individual service components, enabling teams to bring new features to market more quickly and efficiently compared to monolithic architectures.References: The CompTIA Cloud+ certification covers cloud design aspects, including architectural models like microservices, emphasizing their role in facilitating agile development practices and rapid feature release cycles in cloud environments.
