CompTIA CompTIA Certifications CV0-003 Questions & Answers

• Question 81:

  Once a year, a company's private cloud experiences increased activity. The company has a disaster recovery site that is hosted in a public cloud. To avoid investment in additional hardware, which of the following actions would BEST address this issue?

  A. Configure cloud bursting to spin up new VMs automatically and terminate them when usage is back to normal.

  B. Activate the disaster recovery site, and deactivate it when usage is back to normal.

  C. Create a new backup site and decommission it when usage is back to normal.

  D. Manually add memory and CPU to existing VMs, and remove them when usage is back to normal.

  Correct Answer: B

• Question 82:

  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

  Correct Answer: B

  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.

• Question 83:

  A cloud administrator is looking at the company's cloud services bill for the previous month. The administrator notices on the billing dashboard that certain resources are not being billed to any particular department. Which of the following actions will help correct this billing issue?

  A. Check the utilization of the resources.

  B. Modify the chargeback details of the consumer.

  C. Add the resources to the consumer monitoring group.

  D. Modify the tags for all the unmapped resources.

  Correct Answer: A

• Question 84:

  A systems administrator is securing a new email system for a large corporation. The administrator wants to ensure private corporate information is not emailed to external users. Which of the following would be MOST useful to accomplish this task?

  A. DLP

  B. EDR

  C. DNSSEC

  D. SPF

  Correct Answer: A

  The most useful tool to prevent private corporate information from being emailed to external users is data loss prevention (DLP). DLP is a type of security solution that monitors and controls the flow of data in and out of a system or network. It can detect and prevent unauthorized access, transmission, or leakage of sensitive data, such as personal information, financial records, or intellectual property. DLP can also enforce encryption, masking, or deletion of sensitive data to protect its confidentiality.

• Question 85:

  A systems administrator needs to implement a security control that will prevent unknown malware from infecting a system in case the antivirus solution fails. Which of the following should the administrator implement?

  A. A software whitelist

  B. File integrity monitoring

  C. A host-based IDS

  D. Hardened baselines

  Correct Answer: D

• Question 86:

  A systems administrator notices several VMs are constantly ballooning, while the memory usage of several other VMs is significantly lower than their resource allocation. Which of the following will MOST likely solve the issue?

  A. Right-sizing

  B. Bandwidth increase

  C. Cluster placement

  D. Storage tiers

  Correct Answer: A

• Question 87:

  A cloud administrator needs to establish a secure connection between two different locations. Which of the following is the BEST option to implement the secure connection?

  A. HTTPS

  B. IPSec

  C. TLS

  D. SSH

  Correct Answer: B

  The best option to implement a secure connection between two different locations is IPSec (Internet Protocol Security). IPSec is a protocol suite that provides security for IP-based communications over networks. IPSec can encrypt and authenticate the data packets between two endpoints, such as routers, firewalls, or VPN gateways. IPSec can also provide integrity, confidentiality, and replay protection for the data.
