Assume that, on the Alcatel-Lucent 7750 SR, an LSP is configured with one-to-one FRR and node protection. Which of the following statements are FALSE? (Choose two)

A.

Each PLR signals a detour LSP that avoids the downstream node. If the downstream node cannot be avoided, a detour LSP that avoids the downstream link is signaled.

B.

The detour LSP can take one or more hops before merging back on the protected LSP.

C.

The merge point of the protected LSP must be the next-next-hop node

D.

The ingress router will set the local protection desired flag in the session attribute object of the path message to inform all routers along the protected LSP path to establish detour LSPs.

E.

The label recording desired flag must be set in the session attribute object in order for the PLR to know what label to swap when using the detour LSP.

Which of the following message types does RSVP use to set up an LSP? (Choose two)

Which of the following statements best describes the function of an OSPF Type 4 LSA?

A.

A Type 4 LSA is originated by an ABR to describe a route to an ASBR to routers outside the area.

B.

A Type 4 LSA is originated by an ASBR to describe a route to itself to routers outside the area.

C.

A Type 4 LSA is originated by an ABR that is connected to a stub area. The LSA is injected into the backbone area to provide routing information.

D.

A Type 4 LSA is originated by an ABR that is connected to a stub area. The LSA is injected into the stub area to provide routing information.

What is the function of the MPLS label assigned to a packet?

A.

It identifies the FEC.

B.

It specifies the packet's header length

D.

It specifies the type of data contained in the packet

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.

Consider the output shown; why is the label in bold font not in use?
