  A. Analyze
  B. Report
  C. Remediation
  D. identification
  D. identification

  ---

  Explanation

  The phase of vulnerability management that involves looking for existing security vulnerabilities on software applications is known as 'Identification'. This step precedes analysis, reporting, and remediation, focusing on discovering known and unknown vulnerabilities within the system or software to assess the security posture effectively.

• Question 195:

  A cloud engineer wants containers to run the latest version of a container base image to reduce the number of vulnerabilities. The applications in use requite Python 3.10 and ate not compatible with any other version. The containers' images are created every time a new version is released from the source image. Given the container Dockerfile below:

  

  Which of the following actions will achieve the objectives with the least effort?

  A. Perform docker pull before executing docker run.
  B. Execute docker update using a local cron to get the latest container version.
  C. Change the image to use python:latest on the image build process.
  D. Update the Dockerfile to pin the source image version.
  A. Perform docker pull before executing docker run.

  ---

  Explanation

  Performing a "docker pull" before executing "docker run" ensures that the latest version of the container base image is used, aligning with the objective of reducing vulnerabilities. This command fetches the latest image version from the repository, ensuring that the container runs the most up-to-date and secure version of the base image. This approach is efficient and requires minimal effort, as it automates the process of maintaining the latest image versions for container deployments.

  References: Within the CompTIA Cloud+ examination scope, understanding management and technical operations in cloud environments, including container management and security, is critical. This includes best practices for maintaining up-to-date container images to minimize vulnerabilities.

• Question 196:

  A development team recently completed testing changes to a company's web-based CMS in the sandbox environment. The cloud administrator deployed these CMS application changes to the staging environment as part of the next phase in the release life cycle. The deployment was successful, but after deploying the CMS application, the web page displays an error message stating the application is unavailable. After reviewing the application logs, the administrator sees an error message that the CMS is unable to connect to the database.

  Which of the following is the BEST action for the cloud administrator to perform to resolve the issue?

  A. Modify the deployment script to delete and recreate the database whenever the CMS application is deployed.
  B. Modify the ACL to allow the staging environment to access the database in the sandbox environment.
  C. Modify the CMS application deployment to use the previous version and redeploy the application.
  D. Modify the configuration settings of the CMS application to connect to the database in the current environment.
  D. Modify the configuration settings of the CMS application to connect to the database in the current environment.

  ---

  Explanation

  Modifying the configuration settings of the CMS (Content Management System) application to connect to the database in the current environment is what the cloud administrator should do to resolve the issue of web page displaying an error message stating the application is unavailable after deploying CMS application changes to the staging environment. A CMS is a software or platform that allows users to create, manage, and publish web content. A CMS may use a database to store and retrieve web content and information. A staging environment is a testing or pre-production environment that simulates the production environment and allows users to verify and validate changes or updates before deploying them to production. Modifying the configuration settings of the CMS application can help to resolve the issue by ensuring that the CMS application can access and communicate with the database in the current environment, rather than using the previous or default settings that may point to a different or non-existent database.

• Question 197:

  Which of the following strategies requires the development of new code before an application can be successfully migrated to a cloud provider?

  A. Refactor
  B. Rearchitect
  C. Rehost
  D. Replatform
  A. Refactor

  ---

  Explanation

  Refactoring requires the development of new code before an application can be successfully migrated to a cloud provider. It often involves restructuring and optimizing the existing code without changing its external behavior to fit into the new cloud environment.References: Application migration strategies and the requirements for each, like refactoring, are included in cloud migration best practices covered in CompTIA Cloud+.

• Question 198:

  A developer is testing code that will be used to deploy a web farm in a public cloud. The main code block is a function to create a load balancer and a loop to create 1.000 web servers, as shown below:

  

  The developer runs the code against the company's cloud account and observes that the load balancer is successfully created, but only 100 web servers have been created. Which of the following should the developer do to fix this issue?

  A. Request an increase of Instance quota.
  B. Run the code multiple times until all servers are created.
  C. Check the my_web_server () function to ensure it is using the right credentials.
  D. Place the my_load_balancer () function after the loop.
  A. Request an increase of Instance quota.

  ---

  Explanation

  The developer should request an increase of the instance quota from the cloud provider. Cloud services often have a limit on the number of instances that can be created, which is known as an instance quota. If the load balancer is successfully created but the number of web servers is limited to 100, it suggests that the quota has been reached. Increasing the quota will allow the creation of additional web server instances up to the desired number. References: The scenario reflects an understanding of cloud resource management and limitations, which is a part of the CompTIA Cloud+ curriculum, specifically under the domain of Management and Technical Operations.

• Question 199:

  SIMULATION

  You are a cloud engineer working for a cloud service provider that is responsible for an IaaS offering.

  Your customer, who creates VMs and manages virtual storage, has noticed I/O bandwidth issues and low IOPS (under 9000).

  Your manager wants you to verify the proper storage configuration as dictated by your service level agreement (SLA).

  The SLA specifies:

  1. Each SFP on the hypervisor host must be set to the maximum link speed allowed by the SAN array. . All SAN array disk groups must be configured in a RAID 5.

  2. The SAN array must be fully configured for redundant fabric paths. . IOPS should not fall below 14000

  INSTRUCTIONS

  Click on each service processor to review the displayed information. Then click on the drop-down menus to change the settings of each device as necessary to conform to the SLA requirements.

  A. See the explanation for complete solution.

  ---

  Explanation

  Based on the SLA requirements and the information provided in the diagram:

  For the Hypervisor:

  Slot A fiber channel card:

  Port 1 link speed should be set to 16 Gbps since it's connected to Fabric switch A which supports 16 Gbps.

  Port 2 link speed should be set to 8 Gbps because it's connected to Fabric switch B which supports up to 8 Gbps.

  Slot B fiber channel card:

  Port 1 link speed should be set to 16 Gbps since it's connected to Fabric switch A which supports 16 Gbps.

  Port 2 link speed should be set to 8 Gbps because it's connected to Fabric switch B which supports up to 8 Gbps.
