• Question 11:

  Users are reporting that all of a sudden some of the files stored on the remote file server share are becoming corrupted and cannot be opened. A technician is dispatched to the server room to troubleshoot. The technician verifies that no changes to the network infrastructure occurred recently.

  Which of the following tools is MOST likely to reveal why files are becoming corrupted?

  A. Environmental monitor
  B. OTDR
  C. Cable tester
  D. Punch down tool

• Question 12:

  Which of the following remote access types requires a certificate for connectivity?

  A. SSH
  B. PPP
  C. HTTPS
  D. WEP
  A. SSH

  ---

  Secure Shell (SSH) is a cryptographic network protocol for secure data communication, remote command-line login, remote command execution, and other secure network services between two networked computers that connects, via a secure channel over an insecure network, a server and a client (running SSH server and SSH client programs, respectively)

• Question 13:

  A network technician is setting up a wireless access point that would only allow a certain laptop to be able to access the WAP. By using ACL, which of the following would be filtered to ensure only the authorized laptop can access the WAP?

  A. NetBIOS name filtering
  B. IP address filtering
  C. MAC address filtering
  D. Computer name filtering
  C. MAC address filtering

  ---

  MAC Filtering (or EUI filtering, or layer 2 address filtering) refers to a security access control method whereby the 48-bit address assigned to each network card is used to determine access to the network.

  MAC addresses are uniquely assigned to each card, so using MAC filtering on a network permits and denies network access to specific devices through the use of blacklists and whitelists. While the restriction of network access through the use of lists is straightforward, an individual person is not identified by a MAC address, rather a device only, so an authorized person will need to have a whitelist entry for each device that he or she would use to access the network.

• Question 14:

  Linking two or more switches together so that they can share VLAN information is known as which of the following?

  A. Port replicating
  B. Filtering
  C. Trunking
  D. Spoofing
  C. Trunking

• Question 15:

  Which of the following is the wireless encryption standard associated with WPA2?

  A. AES-CCMP
  B. EAP
  C. WEP
  D. 802.1x
  A. AES-CCMP

• Question 16:

  A multi-layer switch operates at which of the following OSI layers?

  A. Layers 1 and 5
  B. Layers 2 and 3
  C. Layers 4 and 5
  D. Layers 5 and 6
  B. Layers 2 and 3

• Question 17:

  Which of the following should be used when throughput to the destination network is a priority?

  A. MTU
  B. Hop count
  C. Reliability of the path
  D. Bandwidth
  D. Bandwidth

• Question 18:

  A technician has resolved a ticket to fix a user's printer and has verified that the user is able to print with no issues.

  Which of the following action steps should the technician perform FIRST?

  A. Document findings and outcomes
  B. Establish a theory of probably cause
  C. Upgrade the printer drivers
  D. Close out the service ticket
  A. Document findings and outcomes

• Question 19:

  Which of the following TCP ports are used by FTP? (Select TWO).

  A. 20
  B. 21
  C. 22
  D. 23
  E. 25
  F. 80
  A. 20
  B. 21

  ---

  FTP uses two ports by default: 21 for sending commands, and 20 for sending data. For instance if you said "FTP " it would make the attempt using port 21. If the session was established, port 20 would be using for the data. NotE. These are the default ports which is what I assume you were asking. A server administrator can however configure FTP to use whatever port he defines.

• Question 20:

  Which of the following would BEST accomplish this?

  A. Switch the channel
  B. Change frequencies
  C. Channel bonding
  D. Increase the signal
  C. Channel bonding
