CV0-002 : CompTIA Cloud+ (CV0-002) : Part 12

  1. An administrator needs to deploy a new release of an application in a way that allows a quick rollback to the previous version of the application. Which of the following is the BEST strategy to apply?

    • Deploy the application to a set of servers in small batches. If a rollback is necessary, restore the previous deployment from snapshots or backups.
    • Deploy the application to a subset of servers that expose the new application. Direct all traffic to these servers. If a rollback is necessary, redirect all traffic to the previous subset of servers.
    • Deploy the application to the servers in a backup datacenter or secondary cloud deployment. Shut down the servers in the primary datacenter, forcing all traffic to the failover location. If a rollback is necessary, restart the primary environment and shut down the secondary environment.
    • Deploy the application to all servers in the datacenter or cloud environment. If a rollback is necessary, undeploy the application and deploy the previous version.
  2. Below is the output from a troubleshooting activity:

    SaaS application is unavailable to a set of users at a single site.
    WAN connectivity was considered to be the cause of the problem.
    Upon testing, it seemed the WAN connectivity was up, but the default gateway was unreachable from the internal users.
    The faulty switch was replaced to bring up the connectivity.
    The incident was documented.

    Based on the methodology, which of the following steps was overlooked during the activity?

    • Problem identification
    • Establish theory of probable cause
    • Verify full system functionality
    • Establish a plan of action and implement the solution
  3. A production IaaS database server contains PCI data and is a critical business capability. The CAB approved a normal code change release for QA and PROD to occur 30 minutes apart and to last a maximum of one hour. The cloud DBA team is 45 minutes behind schedule, so they miss the start time on QA. As the cloud DBA, which of the following is the BEST course of action to apply the code change?

    • Skip QA and apply the code change to PROD to meet time requirements
    • Resubmit another change request for another time for approval
    • Submit an emergency CAB approval to change the time to after business hours
    • Change the time in the CAB request and apply the code change at a more convenient time
  4. A customer wants to remove a user’s access to the SaaS CRM system. Which of the following methods should be executed FIRST?

    • User account removal
    • User account lockout
    • User account password change
    • User account disablement
  5. Since the hypervisors were upgraded to the latest version, each new deployment results in an error being displayed at the orchestrator. To troubleshoot the issue, which of the following should be done FIRST?

    • Verify the domain account is not locked
    • Upgrade the orchestrator to the latest version
    • Confirm the compatibility matrix
    • Upgrade the VMs to the latest version
  6. A company is required to ensure all access to its cloud instance for all users to utilize two-factor authentication. The QA team confirms all functional requirements successfully test. After deployment, all business users report the two-factor authentication is not enforced while accessing the instance. Which of the following would be the MOST likely reason the QA team did not catch the issue?

    • The business users are using the wrong hardware token to log in.
    • The administrator configured to use two-factor authentication by default.
    • The QA team only tested functional requirements.
    • The business users are accessing the instance located in their country.

    • Restore a file server base image from backup
    • Use the file server template to build the file server instances
    • Build the server instances using a boot from a SAN image
  8. A cloud administrator is securing data-at-rest and data-in-transit featured on an IaaS cloud platform. The volume to be secured is mounted storage from the same region and availability zone. The data is transferred via FTP to another Linux server in a secure manner in another availability zone, with the same data-at-rest requirements. Given this scenario, which of the following security tools, services, and/or protocols would satisfy these requirements in the MOST secure manner? (Choose three.)

    • Ensure SSHv1 remote connection protocol is enabled.
    • Ensure SSHv2 remote connection protocol is enabled.
    • Ensure SSLv3 transport protocol is enabled.

    • Ensure AES encryption is enabled.
    • Ensure 3DES encryption is enabled.
    • Ensure MD5 hashing is enabled.
  9. A company has an internal SLA for CPU and RAM oversubscription that should stay below 120%. Storage utilization should stay below 90% with oversubscription below 160%. Given the following:

    CV0-002 Part 12 Q09 042
    CV0-002 Part 12 Q09 042

    Which of the following should be done to meet the SLA?

    • Install a different hypervisor
    • Add RAM to the hypervisors and new shelves to the storage array
    • Add RAM to the hypervisors and increase the CPU clock
    • Add CPU and RAM to the cluster
  10. Company A recently acquired Company B. A cloud administrator needs to give access to the accounting and time-reporting systems for Company B’s employees. Company A’s employees use a single account to access both systems. To give access to Company B’s employees, the cloud administrator should:

    • add Company B’s user account management system to the federated identity system
    • create a new account in each system for Company B’s employees and distribute the credentials
    • create a shared account named “Company B” and distribute the credentials to those who need access
    • add new accounts in Company A’s account management system, mirroring those in Company B’s
  11. A systems administrator created several new VMs on a private cloud and wants to ensure the new baseline still meets corporate guidelines. The administrator finds the following new load numbers on the hosts:
