Which of the following actions should a server administrator take once a new backup scheme has been configured?

  1. Overwrite the backups
  2. Clone the configuration
  3. Run a restore test
  4. Check the media integrity

Answer(s): C

Explanation:

The action that the server administrator should take once a new backup scheme has been configured is to run a restore test. A restore test is a process of verifying that the backup data can be successfully recovered and restored to its original location or a different location. A restore test can help ensure that the backup scheme is working properly, that the backup data is valid and consistent, and that there are no errors or issues during the recovery process. A restore test should be performed periodically and after any changes to the backup configuration or environment.



A systems administrator is performing maintenance on 12 Windows servers that are in different racks at a large datacenter.
Which of the following would allow the administrator to perform maintenance on all 12 servers without having to physically be at each server? (Choose two.)

  1. Remote desktop
  2. IP KVM
  3. A console connection
  4. A virtual administration console
  5. Remote drive access
  6. A crash cart

Answer(s): A,B

Explanation:

The methods that would allow the administrator to perform maintenance on all 12 servers without having to physically be at each server are remote desktop and IP KVM. Remote desktop is a feature that allows a user to access and control another computer over a network using a graphical user interface (GUI). Remote desktop can enable remote administration, troubleshooting, and maintenance of servers without requiring physical presence at the server location. IP KVM (Internet Protocol Keyboard Video Mouse) is a device that allows a user to access and control multiple servers over a network using a single keyboard, monitor, and mouse. IP KVM can provide remote access to servers regardless of their operating system or power state, and can also support virtual media and serial console functions.

A server administrator is experiencing difficulty configuring MySQL on a Linux server. The administrator issues the getenforce command and receives the following output:
># Enforcing

Which of the following commands should the administrator issue to configure MySQL successfully?

  1. setenforce 0
  2. setenforce permissive
  3. setenforce 1
  4. setenforce disabled

Answer(s): A

Explanation:

The command that the administrator should issue to configure MySQL successfully is setenforce 0. This command sets the SELinux (Security-Enhanced Linux) mode to permissive, which means that SELinux will not enforce its security policies and will only log any violations. SELinux is a feature that provides mandatory access control (MAC) for Linux systems, which can enhance the security and prevent unauthorized access or modification of files and processes. However, SELinux can also interfere with some applications or services that require specific permissions or ports that are not allowed by SELinux by default. In this case, MySQL may not be able to run properly due to SELinux restrictions. To resolve this issue, the administrator can either disable SELinux temporarily by using setenforce 0, or permanently by editing the /etc/selinux/config file and setting SELINUX=disabled. Alternatively, the administrator can configure SELinux to allow MySQL to run by using commands such as semanage or setsebool.

Which of the following backup types only records changes to the data blocks on a virtual machine?

  1. Differential
  2. Snapshot
  3. Incremental
  4. Synthetic full

Answer(s): B

Explanation:

The backup type that only records changes to the data blocks on a virtual machine is snapshot. A snapshot is a point-in-time copy of a virtual machine (VM) that captures the state and data of the VM at a specific moment. A snapshot can be created instantly and with minimal overhead, as it only stores the changes made to the VM after the snapshot was taken. A snapshot can be used to restore the VM to its previous state in case of data loss or corruption.
