• Question 41:

  A company wants to move to a multicloud environment and utilize the technology that provides the most portability. Which of the following technology solutions would BEST meet the company's needs?

  A. Bootstrap

  B. Virtual machines

  C. Clusters

  D. Containers

  Correct Answer: D

  The technology that provides the most portability for a multicloud environment is containers. Containers are units of software that package an application and its dependencies into a standardized and isolated environment that can run on any platform or cloud service. Containers are lightweight, scalable, and portable, as they do not depend on the underlying infrastructure or operating system. Containers can also be managed by orchestration tools that automate the deployment, scaling, and networking of containerized applications across multiple clouds.

• Question 42:

  An organization is hosting its dedicated email infrastructure with unlimited mailbox creation capability. The management team would like to migrate to a SaaS-based solution.

  Which of the following must be considered before the migration?

  A. The SaaS provider's licensing model

  B. The SaaS provider's reputation

  C. The number of servers the SaaS provider has

  D. The number of network links the SaaS provider has

  Correct Answer: A

  The licensing model of the SaaS provider is an important factor to consider before migrating to a SaaS-based solution for email infrastructure. The licensing model determines how much the organization will pay for the service, how many mailboxes they can create, what features they can access, and what SLAs they can expect. The organization should compare different SaaS providers' licensing models and choose the one that best suits their needs and budget. Reference: CompTIA Cloud+ Certification Exam Objectives, Domain 1.0 Configuration and Deployment, Objective 1.4 Given a scenario, execute a provided deployment plan.

• Question 43:

  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.

  Correct Answer: D

  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 44:

  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

  Correct Answer: A

  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.

• Question 45:

  Users of a public website that is hosted on a cloud platform are receiving a message indicating the connection is not secure when landing on the website. The administrator has found that only a single protocol is opened to the service and accessed through the URL https://www.comptiasite.com.

  Which of the following would MOST likely resolve the issue?

  A. Renewing the expired certificate

  B. Updating the web-server software

  C. Changing the crypto settings on the web server

  D. Upgrading the users' browser to the latest version

  Correct Answer: A

  Renewing the expired certificate is what would most likely resolve the issue of users receiving a message indicating the connection is not secure when landing on a website that is hosted on a cloud platform and accessed through https:// www.comptiasite.com. A certificate is a digital document that contains information such as identity, public key, expiration date, etc., that can be used to prove one's identity and establish secure communication over a network. A certificate can expire when it reaches its validity period and needs to be renewed or replaced. An expired certificate can cause users to receive a message indicating the connection is not secure by indicating that the website's identity or security cannot be verified or trusted. Renewing the expired certificate can resolve the issue by extending its validity period and restoring its identity or security verification or trust.

• Question 46:

  A systems administrator has been asked to restore a VM from backup without changing the current VM's operating state. Which of the following restoration methods would BEST fit this scenario?

  A. Alternate location

  B. Rolling

  C. Storage live migration

  D. In-place

  Correct Answer: D

• Question 47:

  A company has hired a security firm to perform a vulnerability assessment of its environment. In the first phase, an engineer needs to scan the network services exposed by the hosts.

  Which of the following will help achieve this with the LEAST privileges?

  A. An agent-based scan

  B. A credentialed scan

  C. A network-based scan

  D. An application scan

  Correct Answer: C

  A network-based scan is a type of vulnerability assessment that scans the network services exposed by the hosts without requiring any credentials or agents. This type of scan will help achieve the objective of scanning the network services

  with the least privileges, as it does not need any access to the hosts or their internal configurations. A network-based scan can identify open ports, running services, and potential vulnerabilities on the hosts.
