• Question 341:

  Which IP address is a private address?

  A. 12.0.0.1
  B. 168.172.19.39
  C. 172.20.14.36
  D. 172.33.194.30
  E. 192.169.42.34

• Question 342:

  Which transport layer protocol is best suited for the transport of VoIP data?

  A. RIP
  B. UDP
  C. TCP
  D. OSPF
  E. HTTP
  B. UDP

• Question 343:

  The network manager states, "The only UDP port allowed on this router interface is 53." From the statement, what can be concluded about traffic on the router interface?

  A. DNS traffic is allowed.
  B. RIP traffic is allowed.
  C. SMTP traffic is allowed.
  D. Telnet traffic is allowed.
  A. DNS traffic is allowed.

• Question 344:

  Refer to the exhibit. The network shown in the exhibit is running the RIPv2 routing protocol. The network has converged, and the routers in this network are functioning properly. The FastEthernet0/0 interface on R1 goes down. In which two ways will the routers in this network respond to this change? (Choose two.)

  

  A. All routers will reference their topology database to determine if any backup routes to the 192.168.1.0 network are known.
  B. Routers R2 and R3 mark the route as inaccessible and will not accept any further routing updates from R1 until their hold-down timers expire.
  C. Because of the split-horizon rule, router R2 will be prevented from sending erroneous information to R1 about connectivity to the 192.168.1.0 network.
  D. When router R2 learns from R1 that the link to the 192.168.1.0 network has been lost, R2 will respond by sending a route back to R1 with an infinite metric to the 192.168.1.0 network.
  E. R1 will send LSAs to R2 and R3 informing them of this change, and then all routers will send periodic updates at an increased rate until the network again converges.
  C. Because of the split-horizon rule, router R2 will be prevented from sending erroneous information to R1 about connectivity to the 192.168.1.0 network.
  D. When router R2 learns from R1 that the link to the 192.168.1.0 network has been lost, R2 will respond by sending a route back to R1 with an infinite metric to the 192.168.1.0 network.

• Question 345:

  Refer to the topology below.

  

  Including the address on the Router1 FastEthernet interface, how many hosts can have IP addresses on the LAN to which Router1 is connected?

  A. 6
  B. 14
  C. 62
  D. 128
  B. 14

• Question 346:

  Select and Place:

  

  

• Question 347:

  What source and destination information can be found in the data link layer?

  A. URL
  B. IP address
  C. port number
  D. MAC address
  D. MAC address

• Question 348:

  You run the command debug ip rip on your router and notice this entry:

  08:08:30:

  RIP: build update entries

  08:08:30:

  network 192.168.10.0 metric 16

  What is this information telling you?

  A. It provides the administrative distance for this route.
  B. The route has exceeded its maximum hop count.
  C. There are 16 hops to reach this route.
  D. It establishes the route update timer parameter
  E. The route will be flushed in 16 seconds.
  B. The route has exceeded its maximum hop count.
