Demo Questions

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?

  • A: The packet is flooded out all router interfaces.
  • B: The packet is dropped and an ICMP unreachable message is sent back to the source.
  • C: The packet is silently discarded.
  • D: The packet is flooded out all interfaces and an ICMP unreachable message is sent.



Question 2
Which of the following statements regarding distance vectors protocols are true?  
(Choose two answers).

  • A: RIPv1, RIPv2, and BGP are distance vector protocols.
  • B: OSPF and IS-IS are distance vector protocols.
  • C: Routing tables are exchanged between neighbors; however, no routing table is transmitted beyond the immediate neighbor.
  • D: Distance vector protocols use the Dijkstra SPF algorithm.
  • E: Routers that participate in distance vector routing protocols maintain full knowledge of distant routers and how they interconnect

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?

  • A: Router R3's routing table can only contain one of the routes, which will result in route flapping.
  • 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.
  • C: The networks will be represented with one entry of 10.0.0.0/8 in router R3's routing table.
  • D: The networks will be represented with one entry of 10.0.0.0/24 in router R3's route table.



Question 4
In an IP datagram, which of the following fields identifies the receiving application?

  • A: The protocol field of the transport layer header.
  • B: The port field of the transport layer header.
  • C: The protocol field of the network layer header.
  • D: The port field of the network layer address.



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?

  • A: The corporate head office router will have a default route and the branch site will have a more specific static route.
  • B: The corporate head office router and the branch office router will both have specific static routes.
  • C: The corporate head office router and the branch router will both have default routes.
  • D: The corporate head office router will have a more specific static route and the branch office router will have a default route.

What is the command to configure a static route on the Alcatel-Lucent 7750 SR router R1 to reach the network behind router R2?

  • A: configure router static-route 139.120.121.0/24 next-hop 138.120.199.2
  • B: configure router static-route 139.120.121.0/24 next-hop 138.120.199.1
  • C: configure router static-route 138.120.199.2/24 next-hop 138.120.199.1
  • D: configure router static-route 139.120.121.0/24 next-hop 139.120.121.2



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?

  • A: traceroute 10.2.3.1
  • B: traceroute 10.2.3.1 next-hop 10.1.2.1
  • C: traceroute next-hop 10.1.2.1
  • D: traceroute does not work on the Alcatel-Lucent 7750 SR.
  • E: traceroute 10.1.2.1



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?

  • A: ping static 10.5.5.5
  • B: ping static 0.0.0.0/0
  • C: ping 10.5.5.5
  • D: ping 0.0.0.0



Question 9
What is the default preference value for a static route in the Alcatel-Lucent 7750 SR?

  • A: 0
  • B: 5
  • C: 10
  • D: 15



Question 10
Which of the following statements apply to link state protocol behavior? Choose three answers.

  • A: Routers broadcast the entire route table to all neighbors.
  • B: Information about directly connected links is sent to all neighbors.
  • C: An adjacency database is maintained by each router.
  • D: The sequence number for an update is incremented as it is flooded from router to router.
  • E: The topological database is the same for all routers in a single area.
