A server technician is deploying a server with eight hard drives. The server specifications call for a RAID configuration that can handle up to two drive failures but also allow for the least amount of drive space lost to RAID overhead.
Which of the following RAID levels should the technician configure for this drive array?

  1. RAID 0
  2. RAID 5
  3. RAID 6
  4. RAID 10

Answer(s): C

Explanation:

The technician should configure RAID 6 for this drive array to meet the server specifications. RAID 6 is a type of RAID level that provides fault tolerance and performance enhancement by using striping and dual parity. Striping means dividing data into blocks and distributing them across multiple disks to increase speed and capacity. Parity means calculating and storing extra information that can be used to reconstruct data in case of disk failure. RAID 6 uses two sets of parity information for each stripe, which are stored on different disks. This way, RAID 6 can handle up to two disk failures without losing any data or functionality. RAID 6 also allows for the least amount of drive space lost to RAID overhead compared to other RAID levels that can handle two disk failures, such as RAID 1+0 or RAID 0+1.

Which of the following should an administrator use to transfer log files from a Linux server to a Windows workstation?

  1. Telnet
  2. Robocopy
  3. XCOPY
  4. SCP

Answer(s): D

Explanation:

The administrator should use SCP to transfer log files from a Linux server to a Windows workstation. SCP (Secure Copy Protocol) is a protocol that allows secure file transfer between two devices using SSH (Secure Shell) encryption. SCP can transfer files between different operating systems, such as Linux and Windows, as long as both devices have an SSH client installed. SCP can also preserve file attributes, such as permissions and timestamps, during the transfer.



Users in an office lost access to a file server following a short power outage. The server administrator noticed the server was powered off.
Which of the following should the administrator do to prevent this situation in the future?

  1. Connect the server to a KVM
  2. Use cable management
  3. Connect the server to a redundant network
  4. Connect the server to a UPS

Answer(s): D

Explanation:

The administrator should connect the server to a UPS to prevent this situation in the future. A UPS (Uninterruptible Power Supply) is a device that provides backup power to a server or other device in case of a power outage or surge. A UPS typically consists of one or more batteries and an inverter that converts the battery power into AC power that the server can use. A UPS can also protect the server from power fluctuations that can damage its components or cause data corruption. By connecting the server to a UPS, the administrator can ensure that the server will continue to run or shut down gracefully during a power failure.



Which of the following describes the installation of an OS contained entirely within another OS installation?

  1. Host
  2. Bridge
  3. Hypervisor
  4. Guest

Answer(s): D

Explanation:

The installation of an OS contained entirely within another OS installation is described as a guest. A guest is a term that refers to a virtual machine (VM) that runs on top of a host operating system (OS) using a hypervisor or a virtualization software. A guest can have a different OS than the host, and can run multiple applications or services independently from the host. A guest can also be isolated from the host and other guests for security or testing purposes.
