CV0-002 : CompTIA Cloud+ (CV0-002) : Part 03

  1. A recent advertisement campaign has increased traffic to an e-commerce application that is hosted within a public cloud environment. Customers are reporting that it takes too long to load their pages and submit orders. A cloud administrator looks at the metrics from the environment and sees high utilization of the CPU and memory resources. The cloud provider offers several preconfigured sizes for server template: x-small, small, medium, large, x-large, and 2x-large.

  2. A company wants to leverage a SaaS provider for its back-office services, and security is paramount. Which of the following solutions should a cloud engineer deploy to BEST meet the security requirements?

    • Firewall
    • IPS/IDS
    • Proxy gateway
    • CASB
  3. A company upgraded a hosted vulnerability scanner to the latest version, and now tickets are not being created to assign critical vulnerabilities. After confirming the ticketing issue, all the scanning services are confirmed to be running on the VM. Which of the following is the MOST likely cause and best method to fix the issue?

    • There was an IP change to the VM. Make changes to the server properties.
    • The upgrade has a bug Reboot the server and attempt the upgrade again.
    • The vulnerability scanner is on a different subnet. Open the ports, and it will reconnect.

  4. A system’s application servers need to be patched. The requirements for maintenance work are as follows:

    System downtime is not allowed.
    The application server in use must be in the sane patch status.
    System performance must be maintained during patching work.
    Testing after patching must be done before the application server is in use.
    If any trouble occurs, recover the previous version in ten minutes.

    Which of the following methodologies should be selected?

    • Rolling update
    • Patching directly
    • Blue-green deployment
    • Three staging environments
  5. A software development company is building cloud-ready applications and needs to determine the best approach for releasing software. Which of the following approaches should be used?

    • Use cloud provider tools to remove orphaned resources.
    • Initiate resource reclamation.
    • Run a script to remove stale DNS entries.
    • Update outdated security firewall configurations.
  7. A development team released a new version of an application and wants to deploy it to the cloud environment with a faster rollback and minimal downtime. Which of the following should the cloud administrator do to achieve this goal?

    • Use a rolling deployment to update all the servers in the PROD cloud environment with the new application. To switch to the previous version, repeat the process.
    • Deploy the application to the PROD cloud environment and the previous version to QA. To switch to the previous version, promote the QA environment to PROD.
    • Deploy the application to a subset of servers in the environment and route traffic to these servers. To switch to the previous version, change the route to the non-updated servers.
    • Deploy the application to a staging environment and force a failover to this environment. To restore the previous version, create a backup and restore from the previous night’s backup.
  8. A university is running a DNA decoding project that will take seven years if it runs on its current internal mainframe.

    • Install an SSL certificate and only allow secure connections to the server.
    • Enable two-factor authentication on connections to the database server and log activities.
    • Activate memory encryption on the virtual server and store the certificates remotely.
    • Create a virtual encrypted disk, add it to the virtual server, and have the database write to it.

    Explanation:

    The question talks about data at rest. The only option given that offers a solution for data at rest is to encrypt the disk that the database writes to.

    Two web servers must share the same configurations and service client connections evenly.
    Two database servers must share data and configurations, with only one being used at a time.

    Given the above, which of the following should the administrator propose to BEST meet these requirements? (Select TWO).

    • The web server should be configured with a round-robin DNS with a CNAME record.
    • The web server should be configured with a load balancer with a virtual IP address.
    • The database server should be configured as an active-active cluster.
    • The database server should be configured as an active-passive cluster.
    • The availability aspect of the request does not currently exist in the IaaS cloud platform.
    • The redundancy aspect of the request does not currently exist in the IaaS cloud platform.
  17. In an IaaS model, to which of the following methodologies would the client apply a list of OS patches, assuming approval from CAB has been given?

    • Using a patch management system, identify the guests that require patching, and select and apply the patches.
    • Using a patch management system, identify the applications needing the patch, select the required application in a patch management console, and apply the patches.
    • Using a patch management system, identify the services that require patching, and select and apply the patches.
  18. A cloud administrator has finished building a virtual server template in a public cloud environment. The administrator is now cloning six servers from that template. Each server is configured with one private IP address and one public IP address. After starting the server instances, the cloud administrator notices that two of the servers do not have a public IP address. Which of the following is the MOST likely cause?

    • The maximum number of public IP addresses has already been reached.
    • The two servers are not attached to the correct public subnet.
    • There is no Internet gateway configured in the cloud environment.
    • The two servers do not have enough virtual network adapters attached.
  19. A public cloud provider recently updated one of its services to provide a new type of application load balancer. The cloud administrator is tasked with building out a proof-of-concept using this new service type. The administrator sets out to update the scripts and notices the cloud provider does not list the load balancer as an available option type for deploying this service. Which of the following is the MOST likely reason?

    • The administrator can deploy the new load balancer via the cloud provider’s web console.
    • The administrator needs to update the version of the CLI tool.
    • The administrator needs to write a new script function to call this service.
    • The administrator is not using the correct cloud provider account.
