CompTIA CV0-003 Online Questions & Answers

• Question 141:

  A company wants to move its environment from on premises to the cloud without vendor lock-in. Which of the following would BEST meet this requirement?

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

  ---

  Explanation

  IaaS (Infrastructure as a Service) is what would best meet the requirement of moving an environment from on premises to the cloud without vendor lock-in. Vendor lock- in is a situation where customers become dependent on or tied to a specific vendor or provider for their products or services, and face difficulties

• Question 142:

  An organization's executives would like to allow access to devices that meet the corporate security compliance levels. Which of the following criteria are most important for the organization to consider? (Select two).

  A. Serial number
  B. Firmware
  C. Antivirus version and definition
  D. OS patch level
  E. CPU architecture
  F. Manufacturer
  C. Antivirus version and definition
  D. OS patch level

  ---

  Explanation

  Antivirus version and definition and OS patch level are important criteria for the organization to consider when allowing access to devices that meet the corporate security compliance levels. These criteria can help ensure that the devices are protected from malware and vulnerabilities that could compromise the security of the organization's data and systems. Serial number, firmware, CPU architecture, and manufacturer are not directly related to security compliance levels, although they may be relevant for other purposes such as inventory management or compatibility.

• Question 143:

  A cloud engineer needs to perform a database migration. The database has a restricted SLA and cannot be offline for more than ten minutes per month. The database stores 800GB of data, and the network bandwidth to the CSP is 100MBps.

  Which of the following is the best option to perform the migration?

  A. Copy the database to an external device and ship the device to the CSP.
  B. Create a replica database, synchronize the data, and switch to the new instance.
  C. Utilize a third-party tool to back up and restore the data to the new database.
  D. Use the database import/export method and copy the exported file.
  B. Create a replica database, synchronize the data, and switch to the new instance.

  ---

  Explanation

  The best option to perform the database migration is to create a replica database, synchronize the data, and switch to the new instance. This option can help meet the restricted SLA and avoid offline time for the database. Creating a replica database can help copy the data from the source to the destination without interrupting the database operations. Synchronizing the data can help ensure that the replica database is updated with any changes that occur in the source database during the migration process. Switching to the new instance can help complete the migration and activate the new database in the cloud. This option can also help avoid the network bandwidth limitation and the large size of the data.

• Question 144:

  A cloud engineer is designing a new cloud environment for an organization that requires resilient connectivity to cloud resources over diverse mediums. Which of the following is the best way to ensure resilient networking?

  A. Implement an SD-WAN solution with terrestrial, satellite, and cellular technologies.
  B. Install duplicate commercial circuits for active-passive failover.
  C. Obtain backup satellite connections for failover.
  D. Provide 5G cellular backup circuits with multiple carriers.
  A. Implement an SD-WAN solution with terrestrial, satellite, and cellular technologies.

  ---

  Explanation

  A. Implement an SD-WAN solution with terrestrial, satellite, and cellular technologies: SD-WAN enables diverse networking mediums, ensuring failover and maximum resilience for connectivity. It provides redundancy and prioritizes traffic

• Question 149:

  A company has deployed a new cloud solution and is required to meet security compliance.

  Which of the following will MOST likely be executed in the cloud solution to meet security requirements?

  A. Performance testing
  B. Regression testing
  C. Vulnerability testing
  D. Usability testing
  C. Vulnerability testing

  ---

  Explanation

  Vulnerability testing is a type of security testing that identifies and evaluates the weaknesses or flaws in a system or service that could be exploited by attackers. Vulnerability testing can help meet security compliance requirements when deploying a new cloud solution, as it can reveal any potential security risks or gaps in the cloud environment and provide recommendations for remediation or mitigation. Vulnerability testing can also help improve security posture and performance, as it can prevent or reduce the impact of cyberattacks, data breaches, or service disruptions.

• Question 150:

  A web application has been configured to use auto-scaling for provisioning and deprovisioning more VMs according to the workload. The systems administrator deployed a new CI/CD tool to automate new releases of the web application. During the night, a script was deployed and configured to be executed by the VMs during bootstrapping. Now, the auto-scaling configuration is creating a new VM every five minutes. Which of the following actions will MOST likely resolve the issue?

  A. Reducing the maximum threshold in the auto-scaling configuration
  B. Debugging the script and redeploying it
  C. Changing the automation tool because it is incompatible
  D. Modifying the script to shut down the VM after five minutes
  B. Debugging the script and redeploying it

  ---

  Explanation

  The best way to resolve the issue where the autoscaling configuration is creating a new VM every five minutes after deploying a new CI/CD tool to automate new releases of the web application and configuring a script to be executed by the VMs during bootstrapping is to debug the script and redeploy it. Debugging the script means finding and fixing any errors or bugs in the code or logic of the script that may cause unexpected or undesired behavior, such as triggering the autoscaling condition or failing to complete the bootstrapping process. Redeploying the script means updating or replacing the existing script with the corrected or improved version of the script.
