The management team has mandated the encryption of all server administration traffic.
Which of the following should MOST likely be implemented?

  1. SSH
  2. VPN
  3. SELinux
  4. FTPS

Answer(s): A

Explanation:

SSH stands for Secure Shell and it is a network protocol that provides encrypted and authenticated communication between two hosts. SSH can be used to remotely access and administer a server using a command-line interface or a graphical user interface. SSH can ensure the encryption of all server administration traffic, which can prevent eavesdropping, tampering, or spoofing by unauthorized parties.

An administrator is installing a new file server that has four drive bays available.
Which of the following RAID types would provide the MOST storage as well as disk redundancy?

  1. RAIDO
  2. RAID 1
  3. RAID 5
  4. RAID 10

Answer(s): C

Explanation:

RAID 5 is a RAID level that provides striping with parity, which means that data is distributed across all disks with one disk storing parity information for error correction. RAID 5 can tolerate one disk failure without losing data. RAID 5 provides the most storage as well as disk redundancy out of the four RAID levels given, since it only uses one disk for parity and the rest for data. For example, if four 200GB drives are used in a RAID 5 array, the total storage capacity would be 600GB (200GB x 3), while in RAID 0 it would be 800GB (200GB x 4), in RAID 1 it would be 200GB (200GB x 1), and in RAID 10 it would be 400GB (200GB x 2).

A junior administrator needs to configure a single RAID 5 volume out of four 200GB drives attached to the server using the maximum possible capacity. Upon completion, the server reports that all drives were used, and the approximate volume size is 400GB. Which of the following BEST describes the result of this configuration?

  1. RAID 0 was configured by mistake.
  2. RAID 5 was configured properly.
  3. JBOD was configured by mistake.
  4. RAID 10 was configured by mistake.

Answer(s): B

Explanation:

The output of the configuration shows that RAID 5 was configured properly using four 200GB drives. The approximate volume size of 400GB is correct, since RAID 5 uses one disk for parity and the rest for data. Therefore, the usable storage capacity is three-fourths of the total capacity, which is 600GB out of 800GB. The other RAID levels given would result in different volume sizes: RAID 0 would result in 800GB, RAID 1 would result in 200GB, and JBOD would result in an error since it does not support multiple drives in a single volume.

Which of the following BEST describes a guarantee of the amount of time it will take to restore a downed service?

  1. RTO
  2. SLA
  3. MTBF
  4. MTTR

Answer(s): A

Explanation:

RTO stands for Recovery Time Objective and it is a metric that defines the maximum acceptable amount of time that a system or service can be unavailable after a disaster or disruption. RTO is part of the business continuity planning and disaster recovery planning processes. RTO ensures a guarantee of the amount of time it will take to restore a downed service by setting a target or goal for recovery. RTO can vary depending on the criticality and priority of the service.

Question 130: Answer 'A' should be preferred. Routing through a cable management arm allows the server to be pulled forward in the rack for maintenance and repair without dislodging the power or network cables and helps maintain rack cable management in the enclosed area of the rack for optimal air flow.
