Question # 41

Which of the following are the default settings for the Alcatel-Lucent 7750 SR when using LDP?

Ordered control mode; downstream on demand.

Ordered control mode; downstream unsolicited.

Independent control mode; downstream on demand.

Independent control mode; downstream unsolicited.

Question # 42

Click on the exhibit button below.

If the four LSPs shown use the shared-explicit reservation style, how much bandwidth does CSPF request across a single 1Gbps link?

100Mbps

200Mbps

300Mpbs

600Mbps

700Mbps

Question # 43

You wish to build an LSP originating on router R1, transiting the path R1-R2-R4-R5-R6, and terminating on router R6. How many strict hops would you define in your path statement?

Question # 44

Router R3 signals an LSP, reserving 1Gbps bandwidth on a 10Gbps link. RSVP configuration limits reservable bandwidth to 20 percent on the egress interface. Which of the following statements is true?

The egress RSVP interface has 80 percent bandwidth unreserved.

LSPs can reserve an additional 9.9 Gbps bandwidth on this RSVP interface.

The head end reserves 100Mbps for the LSP

The egress RSVP interface has 1 Gbps bandwidth unreserved.

Question # 45

Which of the following statements regarding DiffServ-TE LSPs is true?

The Maximum Allocation Model (MAM) provides the most efficient bandwidth utilization model

In the Maximum Allocation Model (MAM), each CT receives dedicated bandwidth constraints.

In the Russian Doll Model (RDM), a CT2 LSP automatically preempts a CT1 LSP.

Using the Russian Doll Mode! (RDM), a CT1 LSP may use unreserved CTO bandwidth.

Question # 46

How many bits of the MPLS header are used for the label field?

Question # 47

Which of the following are characteristics of an LSP? (Choose two)

It is unidirectional.

It is bidirectional.

It must always have a secondary path.

It provides a specific tunnel for a FEC through the network.

It always follows the IGP best path.

Question # 48

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)

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.

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

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

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.

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.

Question # 49

Click on the exhibit button below:

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?

Disable route summarization on router R3

Enable LDP aggregate prefix match

Create an import policy to accept these FECs

Disable LDP exact match on the specified FECs
