  A. IP address
  B. Switch serial number
  C. VLAN tag
  D. Loopback plug
  A. IP address

• Question 722:

  Something you have, something you are, and something you know are the three tenets of:

  A. Social engineering
  B. Change management
  C. Remote access
  D. Access control
  D. Access control

• Question 723:

  While monitoring the network, a technician notices that the network traffic to one of the servers is extremely high. Which of the following should the technician use to verify if this is a concern?

  A. Log management
  B. Network diagram
  C. Network baseline
  D. Real time monitor
  C. Network baseline

• Question 724:

  Based on networks 10.8.16.0/22 and 10.8.31.0/21, which of the following is the BEST summarized CIDR notation?

  A. 10.8.0.0/16
  B. 10.8.0.0/19
  C. 10.8.0.0/20
  D. 10.0.0.0/24
  A. 10.8.0.0/16

• Question 725:

  A technician is tasked with connecting a router to a DWDM. The technician connects the router to the multiplexer and confirms that there is a good signal level. However, the interface on the router will not come up. Which of the following is the MOST likely cause?

  A. The wrong wavelength was demuxed from the multiplexer.
  B. The SFP in the multiplexer ismalfunctioning.
  C. There is a dirty connector on the fiber optic cable.
  D. The fiber optic cable is bent in the management tray.
  A. The wrong wavelength was demuxed from the multiplexer.

  ---

  Explanation Explanation/Reference:A multiplexer (or mux) is a device that selects one of several analog or digital input signals andforwards the selected input into a single line. A demultiplexer (or demux) is a device taking a single input signal and selecting one of many dataoutput-lines, which is connected to the single input. Since the signal going in is good, the problem must bewith the signal output. If the correct wavelength was demultiplexed, the interface will be displayed on the router.

• Question 726:

  QoS operates at which of the following OSI model layers? (Select TWO)

  A. Layer 1
  B. Layer 2
  C. Layer 3
  D. Layer 4
  E. Layer 5
  B. Layer 2
  C. Layer 3

• Question 727:

  A network administrator tests a multimode fiber cable from end-to-end on a new link that is down and notices that the dB loss is -.09. Which of the following is the MOST likely cause?

  A. TXRX reversed
  B. dB loss too high
  C. dB loss too low
  D. Bad connectors
  A. TXRX reversed

  Some Ethernet switches support medium dependent interface crossover (MDIX),which allows a switch port to properly configure its leads as transmit (Tx) or receive (Rx) leads. You can interconnect such switches with a straight-through cable (as opposed to a crossover cable). However, if a network device does not support MDIX, it needs an appropriate cable (that is, a crossover cable ) to allow its Tx leads to connect to the Rx leads on a connected device, and vice versa. Therefore, care must be taken when selecting cable types interconnecting network components.

• Question 728:

  The network administrator is configuring a switch port for a file server with a dual NIC. The file server needs to be configured for redundancy and both ports on the NIC need to be combined for maximum throughput. Which of the following features on the switch should the network administrator use?

  A. BPDU
  B. LACP
  C. Spanning tree
  D. Load balancing
  B. LACP

• Question 729:

  Which of the following is a common physical network topology?

  A. Cross-over
  B. Loopback
  C. Star
  D. Straight
  C. Star

  ---

  Explanation Explanation/Reference:A star network consists of one central switch, hub or computer, which acts as a conduit to transmit messages. This consists of a central node, to which all other nodes are connected; this central node provides a common connection point for all nodes through a hub. In star topology, every node (computer workstation or any other peripheral) is connected to central node called hub or switch.

• Question 730:

  A technician, Joe, visits a site that has reported a network down emergency. He immediately reboots the switches and the router since the network is down. Which of the following network troubleshooting methodology steps should Joe have performed FIRST?

  A. Determine if anything has changed
  B. Once a theory is confirmed determine the next step is to resolve the problem
  C. Implement the solution or escalate as necessary
  D. Question the obvious
  A. Determine if anything has changed
