Facility fast reroute with node protection is enabled for an LSP, which of the following is FALSE?

A.

Each PLR signals a bypass tunnel that avoids the next-hop downstream router.

B.

When a failure occurs, the PLR pushs an additional label onto the label stack.

C.

No bypass tunnel is established if the PLR cannot provide node protection.

D.

The head-end router sets the local protection desired flag in the session attribute object.

An Nokia 7750 SR has the BGP configuration shown below. Assuming the router has established BGP sessions to routers R1 and R2, which of the following is TRUE?

A.

Both neighbors R1and R2 should be part of AS 65540.

B.

Neighbor R1should be part of AS 65550, while neighbor R2 should be part of AS 65540.

C.

Neighbor R1should be part of AS 65550, while neighbor R2 should be part of AS 65560.

D.

Both neighbors R1and R2 should be part of AS 65560.

Consider the following:

- Router R2 is an ABR in OSPF Areas 0 and 1.

- Router R2 advertises the aggregate prefix 10.10.10.0/24 into Area 1.

- Router R1 in Area 0 generates LDP labels for FECs 10.10.102/31 and 10.10.10.4/31

Router R3 in Area 1 places these FECs in its LIB, but it does not place them in its LFIB. What can you do on router R3 to make it populate these labels in its LFIB?

A.

Disable route summarization on router R3

B.

Enable LDP aggregate prefix match

C.

Create an import policy to accept these FECs

D.

Disable LDP exact match on the specified FECs

What is the source IP address in an OSPF update?

A.

224.0.0.5

B.

224.0.0.6

C.

The unicast IP address of the interface the update is being sent on.

D.

The system address of the router

Which of the following defines an FEC in traditional IP?

A.

A group of packets that will be forwarded by the router in the same manner, over the same path.

B.

A group of packets that arrive at the router on the same interface,

C.

A group of packets that leave the router on the same interface.

D.

A group of packets that arrive at the router on the same interface, from the same source.

If OSPF is used in a multi-area OSPF network, which of the following statements regarding route summarization is true?

A.

Manual route summarization can only be done on autonomous system border routers.

B.

Manual route summarization must be done on all the backbone routers to be effective. Manual route summarization is optional on the routers in non-backbone areas.

C.

Manual route summarization is done on the ABRs. By default, automatic summarization is done; however, it may not be optimal for all networks.

D.

Manual route summarization is done on the ABRs. By default, no route summarization is done and all routes are advertised to all areas.

Which utility on the Nokia 7750 SR can be used to investigate an MPLS path?

A.

Isp-trace

B.

Idp-trace

C.

Sdp-ping

D.

Svc-ping

E.

Ping

If the Nokia 7750 SR is rebooted after an "admin save'' has been performed, which of the following about mirror services is TRUE?

A.

Only the mirror source must be re-configured.

B.

Only the mirror destination must be re-configured.

C.

Both the mirror destination and mirror source must be re-configured.

D.

Neither the mirror destination nor the mirror source must be re-configured.

A router receives an OSPF database description packet from a neighbor that references an LSA, which is already in the router's LSDB. The sequence number in the DBD packet is lower than the sequence number of the LSA in the LSDB.

What action does the router take?

A.

The router sends a link-state update to its neighbor.

B.

The router sends a link-state acknowledgement to its neighbor.

C.

The router updates the information in its LSDB with the information received from its neighbor.

D.

The router sends a link-state request to its neighbor.

E.

The router takes no action.
