CompTIA CV0-004 Online Questions & Answers

• Question 411:

  A company has ten cloud engineers working on different manual cloud deployments. In the past, engineers have had difficulty keeping deployments consistent.

  Which of the following is the best method to address this issue?

  A. Deployment documentation
  B. Service logging
  C. Configuration as code
  D. Change ticketing
  C. Configuration as code

  ---

  Explanation

  Configuration as Code (CaC) ensures that all cloud deployments are consistent, repeatable, and automated by defining infrastructure configurations in code (e.g., Terraform, AWS CloudFormation, Ansible). This eliminates inconsistencies caused by manual deployments, reduces human errors, and enables version control, making it easier to track changes and collaborate effectively among multiple engineers.

• Question 412:

  Which of the following is used to deliver code quickly and efficiently across the development, test, and production environments?

  A. Snapshot
  B. Container image
  C. Serverless function
  D. VM template
  B. Container image

  ---

  Explanation

  A container image is used to deliver code quickly and efficiently across the development, test, and production environments. Container images are lightweight, standalone, executable software packages that include everything needed to run a piece of software, including the code, runtime, system tools, libraries, and settings.

• Question 413:

  Which of the following storage resources provides higher availability and speed for currently used files?

  A. Warm/HDD
  B. Cold/SSD
  C. Hot/SSD
  D. Archive/HDD
  C. Hot/SSD

  ---

  Explanation

  Hot storage using Solid State Drives (SSD) is designed for data that needs to be accessed frequently and quickly. SSDs provide faster access times compared to HDDs, making them suitable for high-availability and speed-critical files, such as those currently in use or requiring rapid access.

• Question 414:

  A company migrated its CRM system to a SaaS solution. The security team is updating the RAG matrix for the newly migrated CRM. Given the following table:

  

  Which of the following responsibility assignments best aligns with the shared responsibility model for the new CRM?

  A. Data-center security
  B. CRM software security
  C. CRM server patching
  D. CRM development life cycle
  A. Data-center security

  ---

  Explanation

  For the newly migrated SaaS CRM, the responsibility assignment that best aligns with the shared responsibility model is data-center security. In a SaaS model, the cloud service provider (CSP) is responsible for the security of the infrastructure, including data centers, while the customer is typically responsible for the data and possibly the user access management.

  References:

  The shared responsibility model and its implications for different service models are foundational concepts included in the CompTIA Cloud+ certification, under the domain of Governance, Risk, Compliance, and Security.

• Question 415:

  Which of the following is a customer be responsible for in a provider-managed database service? (Select two).

  A. Operating system patches
  B. Table-level permissions
  C. Minor database engine updates
  D. Cluster configuration
  E. Row-level encryption
  F. Availability of hardware for scaling
  B. Table-level permissions
  E. Row-level encryption

  ---

  Explanation

  In a provider-managed database service, the cloud provider typically manages the infrastructure, operating system, and database engine updates. However, the customer is responsible for the data and its security within the database, which includes setting table-level permissions and row-level encryption to ensure that data access and security is managed appropriately.

• Question 416:

  A company has a large environment with multiple VPCs across three regions in a public cloud. The company is concerned about connectivity within the regions.

  Which of the following should the cloud administrator implement?

  A. Peering
  B. A firewall
  C. Network access control
  D. A load balancer
  A. Peering

  ---

  Explanation

  Peering is a networking technique that allows direct and private connection between two or more cloud networks without using the public Internet. Peering can help the cloud administrator improve the connectivity within the regions by reducing the latency, increasing the bandwidth, and enhancing the security of the data transfer. Peering can be implemented between VPCs within the same region or across different regions, depending on the CSP's offerings and the customer's requirements. Peering can also help reduce the network costs by avoiding the use of the Internet gateways or VPNs.

• Question 417:

  Which of the following interfaces is most commonly used for SSDs but not for HDDs?

  A. NVMe
  B. Serial-attached SCSI
  C. SATA
  D. iSCSI
  A. NVMe

  ---

  Explanation

  NVMe (Non-Volatile Memory Express) is a high-speed storage interface designed specifically for SSDs. It utilizes the PCIe (Peripheral Component Interconnect Express) bus, providing significantly faster data transfer speeds and lower latency compared to traditional interfaces like SATA and SAS, which were originally designed for HDDs. Unlike HDDs, NVMe takes advantage of parallel processing capabilities, making it the preferred choice for modern SSDs.

• Question 418:

  A healthcare organization must follow strict compliance requirements to ensure that Pll is not leaked. The cloud administrator needs to ensure the cloud email system can support this requirement.

  Which of the following should the organization enable?

  A. IPS
  B. OLP
  C. ACL
  D. WAF
  B. OLP

  ---

  Explanation

  To ensure that Personally Identifiable Information (PII) is not leaked and to comply with strict healthcare regulations, the organization should enable Data Loss Prevention (DLP). DLP systems are designed to detect and prevent unauthorized access or sharing of sensitive data, making them ideal for securing PII in cloud email systems and ensuring compliance with healthcare industry standards.

  References:

  CompTIA Cloud+ content covers governance, risk, compliance, and security aspects of cloud computing, highlighting the role of DLP in safeguarding sensitive information and maintaining compliance in regulated industries like healthcare.

• Question 419:

  A workload that is running in the cloud has a stable resource consumption without major variations. After applying an application update, RAM utilization increases by 20%. The application can be stopped with no business impact, and utilization is expected to remain constant for the next two months.

  Which of the following is a way to adjust the resources for the application with the least amount of effort?

  A. Add a trend to trigger vertical scaling
  B. Manually adjust the compute size
  C. Set up a load trigger to modify resources
  D. Develop an IaC script to adjust computing attributes
  B. Manually adjust the compute size

  ---

  Explanation

  The workload has a predictable and stable increase in RAM utilization, and the application can be stopped without business impact. Since utilization is expected to remain constant for the next two months, manually adjusting the compute size is the simplest and least-effort solution. There is no need to implement automated scaling mechanisms or develop additional automation for a known, static resource requirement.

• Question 420:

  An administrator deploys a VM with an additional data disk. A developer installs and configures a database application on the data disk. After using the VM to perform very intensive read-and-write operations, the developer reports that the VM seems sluggish.

  Which of the following solutions represents the least amount of work the administrator needs to do to fix the issue?

  A. 1. Create a new VM with more CPU and RAM.2. Have the developer install and configure the database application.
  B. 1. Stop the VM.2. Change the data disk storage type to high performance.3. Start the VM.
  C. 1. Create a new VM with a high-performance data disk.2. Have the developer install and configure the database application.
  D. 1. Stop the VM.2. Detach the data disk.3. Create and attach a new high-performance data disk.4. Start the VM.
  B. 1. Stop the VM.2. Change the data disk storage type to high performance.3. Start the VM.

  ---

  Explanation

  The performance issue is due to the disk type, not CPU or RAM. Changing the existing data disk to a high-performance tier requires minimal effort compared to reinstalling the application or rebuilding the VM.
