CompTIA CV0-004 Online Questions & Answers

• Question 41:

  A web application server farm has the following configuration:

  1. 16vCPU

  2. 128GB of memory

  3. 512GB of local storage

  The performance-testing team reports the web application farm is unable to process requests beyond 5,000 concurrent connections.

  Which of the following should be performed?

  A. Review the memory capacity parameters in the web server
  B. Restart and redeploy the application.
  C. Restart the performance-testing tool.
  D. Review the application configuration
  D. Review the application configuration

• Question 42:

  A cloud engineer is creating a configuration standard to be used on all new cloud deployments. The document should include best practices designed by industry experts.

  Which of the following is the optimal way to complete this task?

  A. Download the ISO 27001 certification document and certify the company's deployment process.
  B. Verify the availability of a CIS benchmark for each in-scope technology
  C. Request from the management team a budget to initiate a SOC 2 attestation
  D. Invite professionals from the local IT community to contribute to the document
  B. Verify the availability of a CIS benchmark for each in-scope technology

  ---

  Explanation

  CIS benchmarks provide industry-recognized best practices for securely configuring technologies. Using these benchmarks ensures the configuration standard aligns with expert consensus and widely accepted security guidance.

• Question 43:

  Which of the following can connect multiple VPCs and an on-premises network?

  A. Subnet
  B. CDN
  C. Peering
  D. Transit gateway
  D. Transit gateway

  ---

  Explanation

  A transit gateway is designed to act as a central hub that connects multiple VPCs and on-premises networks together. It simplifies routing and scales much better than managing many individual point-to-point connections.

• Question 44:

  A cloud developer needs to update a REST API endpoint to resolve a defect.

  When too many users attempt to call the API simultaneously, the following message is displayed: Error: Request Timeout - Please Try Again Later Which of the following concepts should the developer consider to resolve this error?

  A. Server patch
  B. TLS encryption
  C. Rate limiting
  D. Permission issues
  C. Rate limiting

  ---

  Explanation

  To resolve the issue of a REST API endpoint timing out when too many users attempt to call the API simultaneously, the developer should consider implementing rate limiting. Rate limiting controls the number of requests a user can submit in a given amount of time, preventing overuse of the API resources and ensuring availability for all users.

• Question 45:

  A DevOps engineer is initiating a build on a CI/CD pipeline by committing changes to a private repository.

  Which of the following is the purpose of the private repository?

  A. To protect code assets
  B. To deploy to production
  C. To implement version control
  D. To perform integration testing
  A. To protect code assets

  ---

  Explanation

  A private repository restricts access to authorized users and protects source code from unauthorized viewing or modification. In a CI/CD workflow, its primary purpose is to secure valuable code assets while allowing approved developers to collaborate and manage changes.

• Question 46:

  The company's IDS has reported an anomaly. The cloud engineer remotely accesses the cloud instance, runs a command, and receives the following information:

  

  Which of the following is the most likely root cause of this anomaly?

  A. Privilege escalation
  B. Leaked credentials
  C. Cryptojacking
  D. Defaced website
  A. Privilege escalation

  ---

  Explanation

  The output from the 'ps' command indicates there is a process running under the UID (User ID) of 0, which is the root user, and the command that was run is '/var/www/command.py'. Given that the normal Apache processes are running under their own UID (65535), this suggests that a command was executed with root privileges that typically should not have such high-level access. This is a strong indicator of privilege escalation, where an unauthorized user or process gains elevated access to resources that are normally protected from an application or user.

• Question 47:

  Which of the following types of releases best describes the update made to a code repository production release when it changes from version 1.0 to version 1.1?

  A. Alpha
  B. Beta
  C. Minor
  D. Major
  C. Minor

• Question 48:

  A system surpasses 75% to 80% of resource consumption.

  Which of the following scaling approaches is the most appropriate?

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

  ---

  Explanation

  Load scaling is the most appropriate approach when a system surpasses 75% to 80% of resource consumption. This method involves adjusting resources dynamically in response to the current load, ensuring the system can handle increased demand without performance degradation. Load scaling can be automatic, allowing systems to scale up or down based on predefined metrics like CPU usage, memory, or network traffic, providing an efficient way to manage resources and maintain optimal performance.

  References:

  The CompTIA Cloud+ exam objectives include understanding cloud management and technical operations, which encompass knowledge of various scaling approaches, including load scaling, to ensure efficient resource utilization in cloud environments.

• Question 49:

  Which of the following technologies can read the contents of a printed memo?

  A. Document scanning
  B. Sentiment analysis
  C. Text recognition
  D. Natural language processing
  C. Text recognition

  ---

  Explanation

  Text recognition, commonly known as Optical Character Recognition (OCR), is the technology that can read and extract the contents of a printed memo by converting printed text into machine-readable data.

• Question 50:

  A company recently experienced a ransomware attack. The recovery process was slow because the on-site backups were compromised and off-site backups were required.

  Which of the following features would enable a faster recovery if a ransomware attack would happen again?

  A. Integrity
  B. Encryption
  C. Immutability
  D. Replication
  C. Immutability

  ---

  Explanation

  Immutability ensures that backup data cannot be modified, deleted, or encrypted by ransomware or malicious actors. If an attack occurs, the company can quickly restore clean, unaltered backups, significantly speeding up the recovery process. Implementing immutable backups prevents ransomware from compromising backup copies, reducing downtime and data loss.
