Choose the Distance Vector Protocols from the list below:

A. OSPF

B. RIPv1

C. RIPv2

D. IS-IS

An OSPF router receives an update in which the sequence number, age, and checksum are the same as the entry already in the topological database. What action is taken by the router?

A. The link state information is not populated in the database but is forwarded to all neighbors

B. The link state information already in the database is overwritten and the age is reset

C. The link state information is not populated in the database and an acknowledgement is sent

D. The link state information is regarded as old and nothing is done.

What command will show the IS-IS neighbors, and their status on an Alcatel-Lucent 7750 SR?

A. Show isis neighbors

B. Show router isis neighbors

C. Show router isis adjacency

D. Show isis adjacency

What are some of the characteristics of Alcatel-Lucent's implementation of non-stop routing? (Choose two)

A. No protocol extensions required

B. Only supported by OSPF and IS-IS

C. Transparent to routing neighbors

D. Uses Graceful Restart to inter-operate with other vendors

A router sets the E bit in the flags of its Type 1 LSA. What does this indicate?

A. The router is an ABR.

B. The router is an ASBR.

C. The router is at the end of a virtual link.

D. The router's interface is in a stub area.

Router 2 advertises the network 192.168.3.0/24 to router R1 via IS-IS. How can router R1 ensure that it discards the route?

A. Use a prefix list on router R1 to discard all ingress IS-IS routes.

B. Use an export policy and prefix list on router R1.

C. Use an import policy and a prefix list on router R1.

D. This is not possible because IS-IS cannot use import policies.

Which of the following statements regarding OSPF routing updates on a point-to-point link is true?

A. On a point-to-point link, there is no need for a DR and BDR election; all routing updates are sent to

224.0.0.5.

B. On a point-to-point link, a DR and BDR are elected. The DR sends link-state advertisements describing the network.

C. On a point-to-point link, a DR and BDR are elected. To ensure resiliency, both the DR and BDR send link-state advertisements describing the network.

D. On a point-to-point link, there is no need for a DR and BDR election. All routing updates are sent to the unicast address of the neighbor's interface.

The numbers beside the links are the metrics for that link.

Given the diagram, what path will traffic follow from router R1 to router R7, and from router R7 to router R1, if IS-IS is the routing protocol?

A. Router R1 to router R7 will follow (R1-R2-R4-R6-R7). Router R7 to R1 will follow (R7- R6-R4-R2-R1)

B. Router R1 to router R7 will follow (R1-R2-R4-R6-R7). Router R7 to R1 will follow (R7- R6-R5-R3-R1)

C. Router R1 to router R7 will follow (R1-R3-R5-R6-R7). Router R7 to R1 will follow (R7- R6-R4-R2-R1)

D. Router R1 to router R7 will follow (R1-R3-R5-R6-R7). Router R7 to R1 will follow (R7- R6-R5-R3-R1)

Given the contents of the Router LSA, which of the following best describes the local topology of the router?

A. The router has a system interface, two point-to-point interfaces and one broadcast interface.

B. The router has a system interface, two passive interfaces, two point-to-point interfaces and one broadcast interface.

C. The router has a system interface, two point-to-point interfaces and one virtual link.

D. The router has a system interface, two passive interfaces, two point-to-point interfaces and one virtual link.

An OSPFv3 router is attached to a non-OSPF domain that includes networks 2001:DB8:8::/64.2001 .DB8:9::/64 and 2001 :DB8:A::/64. Other routers in the OSPF domain see the prefix 2001, DB8:8::/64, but not the other two prefixes.

What could cause this?

A. The router is not configured as an asbr.

B. The router is not configured as an NSSA.

C. The export policy is not applied to OSPFv3.

D. The prefix list should be 2001:DB8:8::/46
