CompTIA CV0-004 Online Questions & Answers

• Question 101:

  An administrator used a script that worked in the past to create and tag five virtual machines. All of the virtual machines have been created: however, the administrator sees the following results:

  { tags: [ ] }

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

  A. API throttling
  B. Service quotas
  C. Command deprecation
  D. Compatibility issues
  C. Command deprecation

  ---

  Explanation

  The most likely reason for the script creating virtual machines without tags, despite working in the past, is command deprecation. Cloud service providers update their APIs and CLI commands over time, and a previously used command to tag resources might no longer be valid.

  Understanding cloud service APIs and the importance of keeping up with updates is part of cloud technical operations covered in CompTIA Cloud+.

• Question 102:

  Which of the following container storage types loses data after a restart?

  A. Object
  B. Persistent volume
  C. Ephemeral
  D. Block
  C. Ephemeral

  ---

  Explanation

  In the context of container storage, ephemeral storage types are designed to be temporary, losing their data when the container is restarted or deleted. This is in contrast to persistent volumes, which retain data across container restarts and lifecycle, and object and block storage, which are used for specific types of data storage but not inherently temporary. Ephemeral storage is often used for temporary computation data, caching, or any data that doesn't need to persist beyond the lifecycle of the container instance.

• Question 103:

  A development team is ready to release the latest version of an application.

  Which of the following strategies best ensures successful deployment without impacting the bandwidth of company resources?

  A. Blue-green
  B. A/ testing
  C. Rolling
  D. Shadow
  C. Rolling

  ---

  Explanation

  A rolling deployment updates small portions of the environment incrementally, avoiding large simultaneous transfers or resource spikes. This minimizes bandwidth impact on company resources while still ensuring a controlled and successful release.

• Question 104:

  A cloud engineer is reviewing the following Dockerfile to deploy a Python web application:

  

  Which of the following changes should the engineer make lo the file to improve container security?

  A. Add the instruction "JSER nonroot.
  B. Change the version from latest to 3.11.
  C. Remove the EHTRYPOIKT instruction.
  D. Ensure myapp/main.pyls owned by root.
  A. Add the instruction "JSER nonroot.

  ---

  Explanation

  To improve container security, the engineer should add the instruction "USER nonroot" to the Dockerfile.

  This change ensures that the container does not run as the root user, which reduces the risk of privilege escalation attacks. Running containers as a non-root user is a best practice for enhancing security in containerized environments.

  References:

  CompTIA Cloud+ content includes security concerns, measures, and concepts for cloud operations, highlighting container security best practices such as running containers with least privilege to mitigate security risks.

• Question 105:

  Which of the transfer when comparing a multiregional to a single-region cloud platform design?

  A. Storage
  B. Power and cooling
  C. Network
  D. Compliance and regulation
  C. Network

• Question 106:

  A cloud developer resigned from an organization and gave a two-week notice. Within the first week since the developer resigned, a security analyst identifies large volumes of file downloads to the developer's laptop from the source code repository.

  Which of the following security controls would be the best way to mitigate the organization's risk of data loss?

  A. Implementing a policy to stop cloud developers from sharing passwords
  B. Preventing cloud developers from accessing the source code repository
  C. Updating outbound firewall rules to block the cloud developer's IP address
  D. Blocking internet access for employees that resign from the organization
  E. Prohibiting files on the local drive from being transferred to USB drives
  C. Updating outbound firewall rules to block the cloud developer's IP address

• Question 107:

  A company needs an application to manage its CRM system with the least administrative overhead.

  Which of the following models is the best for migrating the infrastructure to the cloud?

  A. PaaS
  B. SaaS
  C. FaaS
  D. IaaS
  B. SaaS

  ---

  Explanation

  Software as a Service (SaaS) provides a fully managed application that is operated, maintained, and updated by the provider. For a CRM system, SaaS offers the least administrative overhead because the company does not need to manage the underlying infrastructure, operating systems, middleware, or application maintenance.

• Question 108:

  A junior cloud administrator was recently promoted to cloud administrator and has been added to the cloud administrator group. The cloud administrator group is the only one that can access the engineering VM.

  The new administrator unsuccessfully attempts to access the engineering VM. However, the other administrators can access it without issue.

  Which of the following is the best way to identify the root cause?

  A. Rebooting the engineering VM
  B. Reviewing the administrator's permissions to access the engineering VM
  C. Allowing connections from 0.0.0.070 to the engineering VM
  D. Performing a packet capture on the engineering VM
  B. Reviewing the administrator's permissions to access the engineering VM

  ---

  Explanation

  The best way to identify the root cause of why the new cloud administrator cannot access the engineering VM is by reviewing the administrator's permissions. It is possible that, despite being added to the cloud administrator group, the specific permissions to access the engineering VM were not properly configured.

  References:

  Permission issues are a common problem in cloud environments, andtroubleshooting such issues is part of the cloud management skills discussed in the CompTIA Cloud+ certification

• Question 109:

  Following the deployment of a new VM, a cloud engineer notices the backup platform has not added the machine to the appropriate job. The backup platform uses a text-based variable for job configuration. This variable is based on the RPO requirements for the workload.

  Which of the following did the cloud engineer forget to configure when deploying the virtual machine?

  A. Tags
  B. RPO
  C. RTO
  D. Server name
  E. Template
  A. Tags

  ---

  Explanation

  Tags are key-value pairs that can be applied to cloud resources to organize, categorize, and filter them.

  Tags can also be used to assign resources to backup jobs based on their RPO requirements. The cloud engineer forgot to configure the appropriate tag for the new VM that matches the text-based variable of the backup platform. Therefore, the backup platform did not add the VM to the correct job.

• Question 110:

  An organization has been using an old version of an Apache Log4j software component in its critical software application.

  Which of the following should the organization use to calculate the severity of the risk from using this component?

  A. CWE
  B. CVSS
  C. CWSS
  D. CVE
  B. CVSS

  ---

  Explanation

  The Common Vulnerability Scoring System (CVSS) is what the organization should use to calculate the severity of the risk from using an old version of Apache Log4j software component. CVSS provides an open framework for communicating the characteristics and impacts of IT vulnerabilities.
