CompTIA CV0-004 Online Questions & Answers

• Question 481:

  A cloud engineer is implementing a deployment strategy with the following requirements: At least two environments for production and development must be supported. Changes in one environment must not impact the other environment. The highest possible availability must be achieved.

  Which of the following deployment strategies should the engineer implement?

  A. Rolling
  B. Blue-green
  C. In-place
  D. Canary
  B. Blue-green

  ---

  Explanation

  The blue-green deployment strategy supports multiple environments (e.g., production and development) while ensuring that changes in one environment do not affect the other. It also achieves high availability by keeping two separate versions of the application: The blue environment represents the current stable version. The green environment is where the new version is deployed and tested. Once the green environment is verified, traffic is switched over from blue to green with minimal downtime. If issues arise, the deployment can be quickly rolled back by reverting traffic to the blue environment.

• Question 482:

  A company has been using a CRM application that was developed in-house and is hosted on local servers.

  Due to internal changes, the company wants to migrate the application to the cloud without having to manage the infrastructure.

  Which of the following services should the company consider?

  A. SaaS
  B. PaaS
  C. XaaS
  D. laaS
  B. PaaS

• Question 483:

  A retail organization is deploying a new point-of-sale system to locations that previously used cash registers.

  Which activities will best help staff adopt the new system? (Select two.)

  A. Documentation
  B. Team collaboration
  C. Gap analysis
  D. Training sessions
  E. Touch points
  F. Progress monitoring
  A. Documentation
  D. Training sessions

• Question 484:

  Which of the following enables CSPs to offer unlimited capacity to customers?

  A. Adequate budget
  B. Global data center distribution
  C. Economies of scale
  D. Agile project management
  C. Economies of scale

• Question 485:

  A video surveillance system records road incidents and stores the videos locally before uploading them to the cloud and deleting them from local storage.

  Which of the following best describes the nature of the local storage?

  A. Persistent
  B. Ephemeral
  C. Differential
  D. Incremental
  B. Ephemeral

  ---

  Explanation

  The nature of the local storage in a video surveillance system that records road incidents and stores the videos locally before uploading them to the cloud and deleting them from local storage is ephemeral.

  Ephemeral storage is temporary and is designed to provide short-term storage for information that changes frequently or is not meant to be persistent.

• Question 486:

  Which of the following effects would a modification to the host affinity configuration in the cloud console have?

  A. Hosts in a multicloud environment will run on the same host.
  B. A VM will run only on a particular underlying host or group of hosts.
  C. Host affinity configuration will have no effect in the cloud environment.
  D. An affinity rule will not disqualify hosts from being eligible to start.
  B. A VM will run only on a particular underlying host or group of hosts.

  ---

  Explanation

  Host affinity rules tie a VM to specific hosts or groups of hosts, ensuring the VM runs only on the designated infrastructure. This is typically used for licensing, performance, or compliance requirements.

• Question 487:

  Which of the following best explains why a project manager would choose to sign a fixed-price contract with a vendor?

  A. The scope of the project deliverable is clearly defined
  B. There is a non-disclosure agreement in place
  C. There are multiple requirements for the product
  D. The PM wants to simplify logistics for the required product
  A. The scope of the project deliverable is clearly defined

• Question 488:

  A cross-site request forgery vulnerability exploited a web application that was hosted in a public laaS network. A security engineer determined that deploying a WAF in blocking mode at a CDN would prevent the application from being exploited again. However, a week after implementing the WAF, the application was exploited again.

  Which of the following should the security engineer do to make the WAF control effective?

  A. Configure the DDoS protection on the CDN.
  B. Install endpoint protection software on the VMs
  C. Add an ACL to the VM subnet.
  D. Deploy an IDS on the laaS network.
  C. Add an ACL to the VM subnet.

  ---

  Explanation

  After a WAF deployment fails to prevent an exploit, adding an Access Control List (ACL) to the Virtual Machine (VM) subnet can be an effective control. ACLs provide an additional layer of security by explicitly defining which traffic can or cannot enter a network segment. By setting granular rules based on IP addresses, protocols, and ports, ACLs help to restrict access to resources, thereby mitigating potential exploits and enhancing the security of the IaaS network.

  CompTIA Cloud+ materials cover governance, risk, compliance, and security for the cloud, including the implementation of network security controls like ACLs, to protect cloud environments from unauthorized access and potential security threats.

• Question 489:

  A write-intensive workload is having frequent performance issues. The workload is running on pay-as-you-go VMs. These VMs use SSDs and have appropriate CPU and RAM sizes. The workload writes millions of small files and has a one-year retention requirement.

  Which of the following actions should be taken?

  A. Use provisioned IOPS volumes.
  B. Increase the VM size.
  C. Switch to reserved VMs.
  D. Change to ephemeral storage.
  A. Use provisioned IOPS volumes.

• Question 490:

  A systems administrator needs to implement a security control that will prevent unknown malware from infecting a system in case the antivirus solution fails.

  Which of the following should the administrator implement?

  A. A software whitelist
  B. File integrity monitoring
  C. A host-based IDS
  D. Hardened baselines
  A. A software whitelist
