Question #1
When a router receives an IP packet, but does not find a match in the routing table for the destination IP address, what actions are performed by the router?
  1. A
    The packet is flooded out all router interfaces.
  2. B
    The packet is dropped and an ICMP unreachable message is sent back to the source.
  3. C
    The packet is silently discarded.
  4. D
    The packet is flooded out all interfaces and an ICMP unreachable message is sent.

Correct Answer:
B

Question #2
Which of the following statements regarding distance vectors protocols are true?
(Choose two answers).
  1. A
    RIPv1, RIPv2, and BGP are distance vector protocols.
  2. B
    OSPF and IS-IS are distance vector protocols.
  3. C
    Routing tables are exchanged between neighbors; however, no routing table is transmitted beyond the immediate neighbor.
  4. D
    Distance vector protocols use the Dijkstra SPF algorithm.
  5. E
    Routers that participate in distance vector routing protocols maintain full knowledge of distant routers and how they interconnect

Correct Answer:
AC

Question #3

Routers R1 R2, and R3 are running a classful routing protocol between them. Assuming that router R1 advertises all directly connected networks, how will these networks be represented in router R3's routing table?
  1. A
    Router R3's routing table can only contain one of the routes, which will result in route flapping.
  2. B
    Router R3's routing table will have one entry for 10.1.1.0/24 and one entry for 10.1.2.0/24.
  3. C
    The networks will be represented with one entry of 10.0.0.0/8 in router R3's routing table.
  4. D
    The networks will be represented with one entry of 10.0.0.0/24 in router R3's route table.

Correct Answer:
C

Question #4
In an IP datagram, which of the following fields identifies the receiving application?
  1. A
    The protocol field of the transport layer header.
  2. B
    The port field of the transport layer header.
  3. C
    The protocol field of the network layer header.
  4. D
    The port field of the network layer address.

Correct Answer:
B

Question #5
Static routing will be used in a network between a corporate head office, with many connected networks, and a branch office, with one connection to the head office. Which of the following best describes the likely configuration?
  1. A
    The corporate head office router will have a default route and the branch site will have a more specific static route.
  2. B
    The corporate head office router and the branch office router will both have specific static routes.
  3. C
    The corporate head office router and the branch router will both have default routes.
  4. D
    The corporate head office router will have a more specific static route and the branch office router will have a default route.

Correct Answer:
D

Question #7
There is an IP host with IP address 10.2.3.1. A static route is created, using the "configure router static-route 10.2.3.0/24 next-hop 10.1.2.1" command. What is the correct traceroute command to test this static route on an Alcatel-Lucent 7750 SR?
  1. A
    traceroute 10.2.3.1
  2. B
    traceroute 10.2.3.1 next-hop 10.1.2.1
  3. C
    traceroute next-hop 10.1.2.1
  4. D
    traceroute does not work on the Alcatel-Lucent 7750 SR.
  5. E
    traceroute 10.1.2.1

Correct Answer:
A

Question #8
Click the exhibit button.

A static route is created on router R1 "using the "static-route 0.0.0.0/0 next-hop 10.3.3.2" command. What command can be used to test the static route on an
Alcatel-Lucent 7750 SR?
  1. A
    ping static 10.5.5.5
  2. B
    ping static 0.0.0.0/0
  3. C
    ping 10.5.5.5
  4. D
    ping 0.0.0.0

  2. B
    5
  3. C
    10
  4. D
    15
