CompTIA CV0-004 Online Questions & Answers

• Question 251:

  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
  A. Community

  ---

  Explanation

  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 252:

  An organization hosts an ERP database in on-premises infrastructure. A recommendation has been made to migrate the ERP solution to reduce operational overhead in the maintenance of the data center.

  Which of the following should be considered when migrating this on-premises database to DBaaS?

  A. Database application version compatibilityDatabase IOPS valuesDatabase storage utilization
  B. Physical database server CPU cache valuePhysical database server DAS typePhysical database server network I/O
  C. Database total user countDatabase total number of tablesDatabase total number of storage procedures
  D. Physical database server operating systemPhysical database server memory configurationPhysical database server CPU frequency
  A. Database application version compatibilityDatabase IOPS valuesDatabase storage utilization

  ---

  Explanation

  These considerations are relevant when migrating to DBaaS. Ensuring compatibility with the database application version is crucial to ensure that the application works seamlessly with the DBaaS offering. Database IOPS (Input/Output Operations Per Second) values and storage utilization are important performance metrics to assess and optimize for efficient operation in the DBaaS environment.

• Question 253:

  An update is being deployed to a web application, and a systems administrator notices the cloud SQL database has stopped running. The VM is responding to pings, and there were not any configuration changes scheduled for the VM.

  Which of the following should the administrator check NEXT?

  A. Logs on the VM
  B. Firewall on the VM
  C. Memory on the VM
  D. vGPU performance on the VM
  A. Logs on the VM

  ---

  Explanation

  Checking the logs on the VM is the next step that the administrator should take if the cloud SQL database has stopped running after an update deployment. Logs are records of events and activities that occur on a system or application. Logs can provide useful information for troubleshooting and identifying the root cause of an issue. The administrator should look for any errors, warnings, or messages that indicate what happened to the SQL database service and why it stopped running.

• Question 254:

  Which of the following best explains the concept of migrating from on premises to the cloud?

  A. The configuration of a dedicated pipeline to transfer content to a remote location
  B. The creation of virtual instances in an external provider to transfer operations of selected servers into a new. remotely managed environment
  C. The physical transportation, installation, and configuration of company IT equipment in a cloud services provider's facility
  D. The extension of company IT infrastructure to a managed service provider
  B. The creation of virtual instances in an external provider to transfer operations of selected servers into a new. remotely managed environment

  ---

  Explanation

  Migrating from on-premises to the cloud generally involves creating virtual instances in an external provider's environment and transferring the operations of selected servers to this new, remotely managed setup. This process allows organizations to leverage the cloud provider's resources and services.

  References: The migration process and strategies are topics included in the Business Principles of Cloud Environments within the CompTIA Cloud+ curriculum.

• Question 255:

  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
  A. PaaS

  ---

  Explanation

  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 256:

  A CI/CD pipeline is used to deploy VMs to an laaS environment. Which of the following can be used to harden the operating system once the VM is running?

  A. Docker
  B. Kubernetes
  C. Git
  D. Ansible
  D. Ansible

  ---

  Explanation

  Ansible can be used to harden the operating system once the VM is running. It is an automation tool that can configure systems, deploy software, and orchestrate more advanced IT tasks such as continuous deployments or zero downtime rolling updates.

  References: Ansible and other configuration management tools are part of the cloud management strategies discussed in the CompTIA Cloud+ certification material.

• Question 257:

  Attendance at recent weekly meetings has been poor. The project manager wants to confirm appropriate participants, meeting frequency, and meeting schedule. Which document should be reviewed?

  A. Project communication plan
  B. Project management plan
  C. Project business case
  D. Project schedule
  A. Project communication plan

  ---

  Explanation

• Question 258:

  An organization was preparing to harden an environment before granting access to external auditors. Vulnerability testing was completed, and only one low-priority, informational vulnerability remained outstanding:

  

  Two weeks later, the auditors review the system on a new machine without an existing browser cache. Credentials are not required when accessing the application login page. Which of the following tests were skipped, causing this issue?

  A. Functionality testing
  B. Usability testing
  C. Regression testing
  D. Penetration testing
  C. Regression testing

• Question 259:

  Users have been reporting that a remotely hosted application is not accessible following a recent migration. However, the cloud administrator is able to access the application from the same site as the users.

  Which of the following should the administrator update?

  A. Cipher suite
  B. Network ACL
  C. Routing table
  D. Permissions
  C. Routing table

  ---

  Explanation

  Since the cloud administrator can access the application from the same site but users cannot, it suggests a possible issue with the network routing. The routing table may need to be updated to ensure that traffic from the users' location is correctly directed to the new location of the remotely hosted application after the migration.

• Question 260:

  A company has hired a security firm to perform a vulnerability assessment of its environment. In the first phase, an engineer needs to scan the network services exposed by the hosts.

  Which of the following will help achieve this with the LEAST privileges?

  A. An agent-based scan
  B. A credentialed scan
  C. A network-based scan
  D. An application scan
  C. A network-based scan

  ---

  Explanation

  A network-based scan is a type of vulnerability assessment that scans the network services exposed by the hosts without requiring any credentials or agents. This type of scan will help achieve the objective of scanning the network services with the least privileges, as it does not need any access to the hosts or their internal configurations. A network-based scan can identify open ports, running services, and potential vulnerabilities on the hosts.
