CompTIA CV0-004 Online Questions & Answers

• Question 211:

  A cloud engineer is deploying a cloud solution that will be used on premises with need-to-know access.

  Which of the following cloud deployment models best meets this requirement?

  A. Community
  B. Public
  C. Private
  D. Hybrid
  C. Private

  ---

  Explanation

  A private cloud deployment model is the most appropriate when the requirement is for 'need-to-know' access, as it offers a more secure environment with resources dedicated to a single organization. It can be hosted on-premises or off-premises but is maintained on a private network, ensuring greater control over the data, security, and compliance when compared to other cloud models.

• Question 212:

  Which of the following commands allows a cloud engineer to create a new template on the local system to later send for code review?

  A. git checkout -b newfeature
  B. git fetch newfeature
  C. git pull newfeature
  D. git commit -m "newfeature"
  A. git checkout -b newfeature

  ---

  Explanation

  git checkout -b newfeature creates a new local branch named newfeature and switches the engineer to that branch. This allows development work to be performed in isolation before the changes are committed, pushed, and submitted for code review.

• Question 213:

  A software development team decides to use a code repository.

  Which of the following is the most likely reason for this decision?

  A. Project management
  B. Version management
  C. Program management
  D. Change management
  B. Version management

  ---

  Explanation

  A code repository is primarily used for version management, allowing developers to track, control, and manage changes to source code over time while enabling collaboration.

• Question 214:

  Project team members submit timesheets through a system that also tracks incurred project costs.

  Which system supports this functionality?

  A. EDRMS
  B. CRM
  C. CMS
  D. ERP
  D. ERP

• Question 215:

  A cloud engineer is reviewing a disaster recovery plan that includes the following requirements:

  1. System state, files, and configurations must be backed up on a weekly basis.

  2. The system state, file, and configuration backups must be tested annually.

  Which of the following backup methods should the engineer implement for the first week the plan is executed?

  A. Differential
  B. Incremental
  C. Snapshot
  D. Full
  D. Full

  ---

  Explanation

  A full backup method should be implemented for the first week the disaster recovery plan is executed. This will ensure that a complete copy of the system state, files, and configurations are backed up. Subsequent backups can be differential or incremental as per the plan.

  References:

  Backup methodologies, including the importance of full backups, are part of the data management strategies in cloud computing covered in the CompTIA Cloud+ certification.

• Question 216:

  A company uses two mobile applications. Application A is used in the United States market, and Application is used in the European Union market with GDPR restrictions. Both applications must comply with PCI standards. The company is consolidating both mobile applications into a single application and must standardize its database back-end system.

  Which of the following is the best option to provision the database for the consolidated mobile application?

  A. Deploying one global database across multiple regions
  B. Using two databases in the same region with different access controls
  C. Implementing two databases in two different regions
  D. Provisioning one database in one region with separate IAM permissions
  C. Implementing two databases in two different regions

  ---

  Explanation

  The consolidated application must comply with both PCI requirements and GDPR regulations. GDPR imposes restrictions on where EU personal data is stored and processed. Implementing two databases in different regions allows EU data to remain within an appropriate region while supporting the United States market separately. This approach helps meet data residency and regulatory requirements while maintaining compliance for both markets.

• Question 217:

  An organization decides to migrate its software source code framework to microservices.

  Which of the following correctly describes this new approach?

  A. Public cloud-managed services
  B. Tightly coupled architecture
  C. Private cloud-managed services
  D. Loosely coupled architecture
  D. Loosely coupled architecture

  ---

  Explanation

  Microservices use a loosely coupled architecture where each service operates independently and communicates through APIs. This improves scalability, flexibility, and maintainability compared to tightly coupled monolithic designs.

• Question 218:

  A cloud engineer is migrating a company-hosted application to a cloud provider. The data needs to be secure while stored on the third-party system.

  Which of the following would best ensure that the data is secure? (Choose two.)

  A. Hashing
  B. Encoding
  C. SAML
  D. AES
  E. TLS
  F. SSL
  A. Hashing
  D. AES

• Question 219:

  Which of the following is the most cost-effective and efficient strategy when migrating to the cloud?

  A. Retire
  B. Replatform
  C. Retain
  D. Refactor
  A. Retire

  ---

  Explanation

  The most cost-effective and efficient strategy when migrating to the cloud can often be to 'retire' or turn off legacy systems that are no longer useful or necessary. This avoids spending resources on migrating and maintaining systems that do not provide value in a cloud environment.

  References:

  Cloud migration strategies, including retiring outdated systems, are part of the decision-making process for cloud adoption in the CompTIA Cloud+ certification material.

• Question 220:

  A bank was recently hacked. The bank reviews the logs to see how the attack occurred. The security administrator suspects the logs were manipulated because no traces of the attack can be found in them.

  Which of the following should have been enabled before the attack occurred?

  A. Metric and alerts
  B. Tracing and aggregation
  C. Dashboard and reporting
  D. Versioning and immutability
  D. Versioning and immutability

  ---

  Explanation

  Versioning and immutability ensure that logs cannot be altered or deleted, preserving their integrity and providing reliable evidence for forensic analysis.
