  A. Enable IPv6 on the workstation.

  B. Create a local hosts file.

  C. Examine the DHCP scope configuration.

  D. Configure an APIPA reservation.

  Correct Answer: C

• Question 104:

  A server administrator is gathering business requirements to determine how frequently backups need to be performed on an application server. Which of the following is the administrator attempting to establish?

  A. MTBF

  B. RPO

  C. MTTR

  D. RFC

  Correct Answer: B

• Question 105:

  The network's IDS is giving multiple alerts that unauthorized traffic from a critical application server is being sent to a known-bad public IP address. One of the alerts contains the following information:

  Exploit Alert

  Attempted User Privilege Gain 2/2/07-3:09:09 10.1.200.32 --> 208.206.12.9:80

  This server application is part of a cluster in which two other servers are also servicing clients. The server administrator has verified the other servers are not sending out traffic to that public IP address. The IP address subnet of the application servers is 10.1.200.0/26. Which of the following should the administrator perform to ensure only authorized traffic is being sent from the application server and downtime is minimized? (Choose two.)

  A. Disable all services on the affected application server.

  B. Perform a vulnerability scan on all the servers within the cluster and patch accordingly.

  C. Block access to 208.206.12.9 from all servers on the network.

  D. Change the IP address of all the servers in the cluster to the 208.206.12.0/26 subnet.

  E. Enable GPO to install an antivirus on all the servers and perform a weekly reboot.

  F. Perform an antivirus scan on all servers within the cluster and reboot each server.

  Correct Answer: BC

• Question 106:

  A server administrator is connecting a Linux server to a storage array. The administrator wants to use a file-based storage protocol to store data on the server. Which of the following protocols will the administrator MOST likely use?

  A. NFS

  B. FCoE

  C. iSCSI

  D. CIFS

  Correct Answer: A

• Question 107:

  A hardware technician is installing 19 1U servers in a 42-unit rack. The technician needs to allocate enough space per server for optimal air flow.

  Which of the following unit sizes should be allocated per server?

  A. 1U

  B. 2U

  C. 3U

  D. 4U

  Correct Answer: A

  This unit size would be sufficient to allocate per server for optimal airflow, as rack mount servers and racks are designed for airflow with all panels and bezels on and all U's filled. Leaving gaps between servers or removing panels and covers may disrupt the airflow and cause overheating. The technician should also ensure that the airflow is front to back, as vertical airflow is likely to be ineffective. Additionally, the technician should use blanking panels, fan trays, or other devices to manage hot spots and improve circulation.

• Question 108:

  A server administrator needs to ensure all Window-based servers within a data center have RDP disabled. There are thousands of servers performing various roles. Which of the following is the BEST way to meet this requirement?

  A. Run chkconfig --level 345 RDP off.

  B. Create a PowerShell script to disable the RDP service.

  C. Run chkconfig --list RDP.

  D. Create a Bash shell script to disable the Windows Remote Management service.

  E. Create a GPO to disable the Windows Remote Management service

  Correct Answer: B

• Question 109:

  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?

  A. RAID 0

  B. RAID 1

  C. RAID 5

  D. RAID 10

  Correct Answer: D

  RAID 10 would provide the MOST storage as well as disk redundancy out of the given options.

  RAID 0 provides no redundancy and only offers increased performance by striping data across multiple drives.

  RAID 1 provides disk redundancy but only half the total storage capacity since each disk is a mirror of the other.

  RAID 5 provides a good balance of storage and redundancy by striping data across multiple disks with parity data distributed among the disks. However, it requires at least three drives and can only withstand the failure of one disk.

  RAID 10, also known as RAID 1+0, provides both disk redundancy and increased storage capacity by mirroring two drives and then striping data across the mirrored pairs. This configuration requires at least four drives and can withstand the

  failure of one drive in each mirrored pair.

• Question 110:

  A server administrator is installing servers in a rack that does not have rack unit markings on the sides. The available open space for the new servers is approximately 3.5in (8.9cm) high. Which of the following is the LARGEST server size that can fit in this space?

  A. 1U

  B. 2U

  C. 3U

  D. 4U

  Correct Answer: B

  This server size can fit in this space, as one rack unit is equal to 1.75in (4.45cm) high. Therefore, a 2U server is 2 x 1.75in = 3.5in (8.9cm) high, which matches the available open space for the new servers.
