    • Enable DLP
    • Configure microsegmentation
    • Enable DNSSEC

    • Simultaneous multithreading
    • Bus speed
    • L3 cache
    • Instructions per cycle

  8. A cloud administrator is building a new VM for a network security appliance. The security appliance installer says the CPU clock speed does not meet the requirements.

    Which of the following will MOST likely solve the issue?

    • Move the VM to a host with a faster CPU
    • Add more vCPUs to the VM
    • Enable CPU masking on the VM
    • Enable hyperthreading on the virtual host

  9. An organization will be deploying a web application in a public cloud with two web servers, two database servers, and a load balancer that is accessible over a single public IP.

    Taking into account the gateway for this subnet and the potential to add two more web servers, which of the following will meet the minimum IP requirement?

    • 192.168.1.0/26
    • 192.168.1.0/27
    • 192.168.1.0/28
    • 192.168.1.0/29

  10. A cloud administrator checked out the deployment scripts used to deploy the sandbox environment to a public cloud provider. The administrator modified the script to add an application load balancer in front of the web-based front-end application. The administrator next used the script to recreate a new sandbox environment successfully, and the application was then using the new load balancer.

    The following week, a new update was required to add more front-end servers to the sandbox environment. A second administrator made the necessary changes and checked out the deployment scripts. The second administrator then ran the script, but the application load balancer was missing from the new deployment.

    Which of the following is the MOST likely reason for this issue?

    • The license limit on the number of server deployments allowed per month was exceeded
    • The deployment script changes made by the first administrator were not checked in and committed
    • The new server images were incompatible with the application load-balancer configuration
    • The application load balancer exceeded the maximum number of servers it could use

  11. A systems administrator is using VMs to deploy a new solution that contains a number of application VMs.

    Which of the following would provide high availability to the application environment in case of hypervisor failure?

    • Anti-affinity rules
    • Cold migration
    • Live migration
    • Affinity rules

  12. A company just successfully completed a DR test and is ready to shut down its DR site and resume normal operations.

    Which of the following actions should the cloud administrator take FIRST?

    • Initiate a failover
    • Restore backups
    • Configure the network
    • Perform a failback

  13. A cloud administrator has built a new private cloud environment and needs to monitor all computer, storage, and network components of the environment.

    Which of the following protocols would be MOST useful for this task?

    • SMTP
    • SCP
    • SNMP
    • SFTP

  14. Company A has acquired Company B and is in the process of integrating their cloud resources. Company B needs access to Company A’s cloud resources while retaining its IAM solution.

    Which of the following should be implemented?

    • Multifactor authentication
    • Single sign-on
    • Identity federation
    • Directory service

  15. After accidentally uploading a password for an IAM user in plain text, which of the following should a cloud administrator do FIRST?

  17. A systems administrator is troubleshooting performance issues with a Windows VDI environment. Users have reported that VDI performance has been slow since the images were upgraded from Windows 7 to Windows 10. This VDI environment is used to run simple tasks, such as Microsoft Office. The administrator investigates the virtual machines and finds the following settings:

    – 4 vCPU
    – 16GB RAM
    – 10Gb networking
