CompTIA CV0-004 Online Questions & Answers

• Question 71:

  An on-premises data center is located in an earthquake-prone location. The workload consists of real-time, online transaction processing.

  Which of the following data protection strategies should be used to back up on-premises data to the cloud while also being cost effective?

  A. Remote replication for failover
  B. A copy that is RAID 1 protected on spinning drives in an on-premises private cloud
  C. A full backup to on-site tape libraries in a private cloud
  D. Air-gapped protection to provide cyber resiliency
  A. Remote replication for failover

  ---

  Explanation

  Remote replication for failover is the data protection strategy that should be used to back up on-premises data to the cloud for an earthquake-prone location. It provides real-time or near-real-time copying of data to a remote location, which can be quickly activated in case the primary site fails.

  References:

  Disaster recovery strategies, including remote replication for failover, are part of the cloud-based data protection methods covered in the CompTIA Cloud+ certification.

• Question 72:

  Which of the following storage types should be used by a data lake implemented on a CSP?

  A. Object
  B. Block
  C. File
  D. Ephemeral
  A. Object

  ---

  Explanation

  Object storage is the preferred storage type for data lakes because it is highly scalable, cost-effective, and designed to store massive amounts of structured, semi-structured, and unstructured data. It also supports metadata tagging and analytics workloads commonly associated with data lake architectures.

• Question 73:

  An organization and its customer both signed an obligatory agreement that requires both parties to encrypt the data exchanged between the organization and the customer environment.

  Which of the following best describes this agreement?

  A. Regulatory
  B. Litigation
  C. Contractual
  D. Subscription
  C. Contractual

  ---

  Explanation

  A contractual agreement is a mutually binding obligation between parties that can mandate specific security requirements such as encrypting exchanged data.

• Question 74:

  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 75:

  Which of the following would a customer most likely be accountable for in a shared responsibility model?

  A. Security of data in the data centers
  B. Security in the cloud
  C. Security of the application
  D. Security of the cloud
  C. Security of the application

  ---

  Explanation

  In the shared responsibility model, the cloud provider is responsible for the security of the cloud (infrastructure, hardware, data centers), while the customer is responsible for security in the cloud, which includes securing their applications, data, and configurations.

• Question 76:

  A cloud security analyst is looking for existing security vulnerabilities on software applications.

  Which of the following describes this vulnerability management phase?

  A. Analyze
  B. Report
  C. Remediation
  D. identification
  D. identification

  ---

  Explanation

  The phase of vulnerability management that involves looking for existing security vulnerabilities on software applications is known as 'Identification'. This step precedes analysis, reporting, and remediation, focusing on discovering known and unknown vulnerabilities within the system or software to assess the security posture effectively.

• Question 77:

  An engineer wants to scale several cloud workloads on demand.

  Which of the following approaches is the most suitable?

  A. Load
  B. Scheduled
  C. Manual
  D. Trending
  A. Load

  ---

  Explanation

  Load scaling is the most suitable approach for scaling several cloud workloads on demand. It automatically adjusts the number of active servers in a cloud environment based on the current load or traffic, ensuring that resources are efficiently utilized to meet demand without manual intervention. This approach helps maintain optimal performance and availability, particularly during unexpected surges in workload or traffic.

  References:

  Understanding cloud management and technical operations, including scaling strategies, is crucial for optimizing resource utilization and performance in cloud environments, as outlined in the CompTIA Cloud+ objectives.

• Question 78:

  A DevOps engineer is performing maintenance on the mail servers for a company's web application. Part of this maintenance includes checking core operating system updates. The servers are currently running version 3.2 of the operating system. The engineer has two update options--one to version 4.1 and the other to version 3.7. Both versions are fully supported by the operating system manufacturer.

  Which of the following best describes the action the engineer should take?

  A. Upgrade to 3.7 in the development environment.
  B. Upgrade to 4.1 on one production server at a time.
  C. Read the release notes on version 4.1.
  D. Schedule a maintenance window and upgrade to 3.7 in the production environment.
  A. Upgrade to 3.7 in the development environment.

  ---

  Explanation

  Before making any updates to the production environment, the best course of action is to perform the update in a development or testing environment. Upgrading to version 3.7, which is a minor update, is generally less risky and should be tested first to ensure compatibility and stability before considering the major update to version 4.1.

  References:

  The process of updating and maintaining servers, including the validation of updates in a non-production environment, is part of the technical operations management covered in CompTIA Cloud+.

• Question 79:

  An e-commerce business operates its web applications using a microservices-based architecture. These application instances run on multiple VMs in the cloud and are interconnected through discovery. As the business grows, prioritizing rapid scaling will be crucial.

  Which of the following best meets the business's scaling needs?

  A. Manually tuning the VM size to meet demand based on estimates and projections
  B. Configuring vertical scaling to increase system resources on a set schedule
  C. Automatically provisioning more application instances when CPU usage hits a set threshold
  D. Setting up a new colocated data center to handle extra load based on specific criteria
  C. Automatically provisioning more application instances when CPU usage hits a set threshold

  ---

  Explanation

  Automatically provisioning additional application instances when CPU usage reaches a defined threshold provides horizontal scaling, which is ideal for microservices architectures. This approach allows the environment to respond rapidly to increases in demand, improves availability, and scales resources efficiently without manual intervention.

• Question 80:

  A project team analyzes an existing customer service process, identifies improvement areas, and defines desired outcomes.

  Which of the following best describes this analysis?

  A. Process improvement
  B. Business objectives
  C. Current state versus future state
  D. Project success criteria
  C. Current state versus future state
