CompTIA CV0-004 Online Questions & Answers

• Question 351:

  A cloud engineer discovers that two nodes experience resource exhaustion during the holidays. This creates a denial of service on the web application. Adding a third node is not an option because of budgetary constraints.

  Which of the following scaling approaches helps minimize resource exhaustion?

  A. Event trigger
  B. Load trigger
  C. Vertical scaling
  D. Horizontal scaling
  C. Vertical scaling

  ---

  Explanation

  Vertical scaling increases the resources (CPU, memory, etc.) available to existing nodes without adding new ones. This approach helps prevent resource exhaustion when adding additional nodes is not feasible due to budget constraints.

• Question 352:

  An administrator configures three subnets to the corporate network. All servers should communicate with the main corporate network and access the internet. The administrator creates the following configurations:

  

  After configuring the networks, the administrator recognizes an issue with the configuration.

  Which of the following can the administrator change in one step to accomplish the goal?

  A. Remove source 192.168.12.0/24 and destination 192.168.1.0/24 from the routing table.
  B. Replace destination 192.168.1.0/24 with destination 192.168.0.0/24.
  C. Add source 192.168.12.0/24 and destination 192.168.0.0/24 to the routing table.
  D. Reconfigure Network 4 to 192.168.13.0/24.
  B. Replace destination 192.168.1.0/24 with destination 192.168.0.0/24.

• Question 353:

  A company developed a product using a cloud provider's PaaS platform and many of the platform-based components within the application environment.

  Which of the following would the company MOST likely be concerned about when utilizing a multicloud strategy or migrating to another cloud provider?

  A. Licensing
  B. Authentication providers
  C. Service-level agreement
  D. Vendor lock-in
  D. Vendor lock-in

  ---

  Explanation

  Vendor lock-in is a situation where a customer becomes dependent on a specific vendor for products or services and faces high switching costs or barriers when trying to change vendors. Vendor lock-in is most likely to be a concern for a company that developed a product using a cloud provider's PaaS platform and many of the platform-based components within the application environment when utilizing a multicloud strategy or migrating to another cloud provider, as it can limit the flexibility, scalability, and portability of the product and increase the complexity, risk, and cost of moving or integrating with other cloud platforms or providers.

• Question 354:

  A customer's facility is located in an area where natural disasters happen frequently. The customer requires the following:

  1. Data resiliency due to exposure to frequent natural disasters

  2. Data localization because of privacy regulations in the country

  3. High availability

  Which of the following cloud resources should be provisioned to meet these requirements?

  A. Storage in a separate data center located in same region
  B. An on-premises private cloud carrying duplicate data
  C. Storage in an availability zone outside the region
  D. Storage in the same availability zone as the primary data
  C. Storage in an availability zone outside the region

  ---

  Explanation

  To meet the requirements of data resiliency, data localization, and high availability in a region prone to natural disasters, the customer should provision storage in an availability zone outside the region. This ensures that data is not affected by regional disasters and complies with data localization by remaining within the country's borders, while also providing high availability.

  Disaster recovery and high availability strategies, including the use of multiple availability zones, are discussed in the CompTIA Cloud

  + certification material.

• Question 355:

  A cloud architect is evaluating a cloud migration strategy for a CRM application. The CRM application's most important requirement is application portability.

  Which of the following factors is most important for the cloud architect to consider?

  A. Management overhead
  B. Vendor lock-in
  C. Platform compatibility
  D. Service availability
  B. Vendor lock-in

  ---

  Explanation

  Application portability requires the ability to move an application between cloud providers or environments with minimal changes. Vendor lock-in directly impacts portability because reliance on provider-specific services, APIs, or technologies can make migration difficult and costly. Minimizing vendor lock-in helps ensure the CRM application can be moved or deployed across different platforms as needed.

• Question 356:

  Attendance at recent weekly meetings has been poor. The project manager wants to confirm appropriate participants, meeting frequency, and meeting schedule.

  Which document should be reviewed?

  A. Project communication plan
  B. Project management plan
  C. Project business case
  D. Project schedule
  A. Project communication plan

• Question 357:

  A cloud administrator needs to collect process-level, memory-usage tracking for the virtual machines that are part of an autoscaling group.

  Which of the following is the best way to accomplish the goal by using cloud-native monitoring services?

  A. Configuring page file/swap metrics
  B. Deploying the cloud-monitoring agent software
  C. Scheduling a script to collect the data
  D. Enabling memory monitoring in the VM configuration
  B. Deploying the cloud-monitoring agent software

  ---

  Explanation

  To collect process-level, memory-usage tracking for virtual machines, deploying cloud-monitoring agent software is the best approach. The agent can gather detailed system metrics and send them to the cloud-native monitoring services for analysis and visualization.

• Question 358:

  A high-priority negative risk triggers a risk indicator, but the issue has not yet occurred.

  What should the project team do next?

  A. Execute the contingency plan
  B. Perform a workaround
  C. Escalate to senior management
  D. Assign a risk owner
  A. Execute the contingency plan

• Question 359:

  A company hosts its server in a public IaaS cloud. The company's management decides to migrate the servers to a different geographical region that is closer to the user base. A cloud administrator creates a new environment in that geographical region.

  Which of the following is the BEST way to migrate the VM from the original geographic region to the new region?

  A. 1. Create a full backup of the VM.2. Copy the backup files into the new region using FTP.3. Restore the VM from the backup files.
  B. 1. Create a VM image.2. Export the VM image to the new region using vendor's tools.3. Deploy a new VM based on the created image.
  C. 1. Create a VM clone.2. Copy the clone into the new region using FTP.3. Apply the network and security groups from the new region to the cloned VM and start it.
  D. 1. Create a new VM in the new region.2. Restore a full-system backup from the original VM.3. Apply the network and security groups from the original region to the new VM.
  D. 1. Create a new VM in the new region.2. Restore a full-system backup from the original VM.3. Apply the network and security groups from the original region to the new VM.

• Question 360:

  A cloud administrator is upgrading a cloud environment and needs to update the automation script to use a new feature from the cloud provider. After executing the script, the deployment fails.

  Which of the following is the MOST likely cause?

  A. API incompatibility
  B. Location changes
  C. Account permissions
  D. Network failure
  A. API incompatibility

  ---

  Explanation

  API incompatibility is the most likely cause of the failure of an automation script to use a new feature from the cloud provider. API (Application Programming Interface) is a set of rules or specifications that defines how different software components or systems can communicate and interact with each other. API incompatibility is a situation where an API does not work or function properly with another software component or system due to differences or changes in versions, formats, parameters, etc. API incompatibility can cause errors or issues when using an automation script to deploy or configure cloud resources or services, especially if the script is not updated or modified according to the new API specifications.
