Options:
A.

It sets the address to the system address of the head-end router.

B.

It sets the address to the next upstream hop from the ERO.

C.

It sets the address to the next upstream hop from the PSB.

D.

It sets the address to the next upstream hop from the RRO.

Questions # 2:

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

Options:
A.

Per-platform label space, conservative retention mode

B.

Per-interface label space, conservative retention mode

C.

Per-platform label space, liberal retention mode

D.

Per-interface label space, liberal retention mode

Questions # 3:

In MPLS, how is the label range 0 ?15 used?

Options:
A.

Static LSPs

B.

Reserved use

C.

Vendor proprietary use

D.

Management LSPs

E.

Dynamic LSPs

Questions # 4:

Which one of the following statements regarding RSVP LSP configuration is true?

Options:
A.

LSPs must always terminate on a system ID.

B.

MPLS and RSVP must be enabled on all routers.

C.

Interfaces must be individually created in RSVP.

D.

Path definitions must include at least one hop entry.

Questions # 5:

Which one of the following statements regarding the detour object transported in the detour path message is true?

Options:
A.

The PLR sends it downstream with the RRO.

B.

The PLR sends it downstream with the ERO.

C.

It associates all detours with the source PLR.

D.

The MP sends it upstream with the RESV message.

Questions # 6:

Which of the following statements regarding per-platform label space are true? Choose two answers.

Options:
A.

A separate label is used for each interface that the FEC is advertised on.

B.

It uses fewer label resources than a per-interface label space.

C.

It is typically used when the device has ATM or Frame Relay interfaces.

D.

It uses more label resources than a per-interface label space.

E.

A single label may be assigned to an FEC and used across all interfaces of the same router.

F.

It is only valid when the LDP peers are directly connected over an interface, and the label is only going to be used for traffic sent over that interface.

Questions # 7:

An Alcatel-Lucent 7750 SR enabled with LDP has multiple equal cost paths to a given FEC. After ECMP is enabled, which of the following is FALSE?

Options:
A.

The router has new entries added for the given FEC in its LIB.

B.

The router has new entries added for the given FEC in its FIB.

C.

The router generates a single label for the given FEC and advertises it to all its peers,

D.

The router has multiple LSP tunnels for the given FEC.

Questions # 8:

Which of the following is a primary cause of IP hyper-aggregation?

Options:
A.

IP routing protocols do not always select the best route to a destination.

B.

IP routing protocols always select multiple routes to a destination.

C.

IP routing protocols do not make use of all available network attributes to select a path

D.

Improper network design results in limited network path redundancy.

Questions # 9:

What MPLS function should be performed by a router that receives a data packet containing an MPLS label value of 3?

Options:
A.

A router will never receive a packet containing this label value.

B.

Request a new label from the peer that provided this label.

C.

Pop the label.

D.

PUSH an additional label onto the label stack.

E.

Signal a new label to the peer that sent the packet.

Questions # 10:

Click on the exhibit.

Question # 10

Router R2 advertises an OSPF summary route 10.10.10.0/24 into Area 1. Router R3 receives labels for individual FECs 10.10.10.2/32 and 10.10.10.4/32. These two FECs are installed in router R3's LIB but not in the LFIB. What needs to be done on router R3 to install these labels into its LFIB?

Options:
A.

Disable route summarization on router R3.

B.

Enable LDP aggregate prefix match.

C.

Create an import policy to accept 10.10.10.2/32 and 10.10.10.4/32.

D.

Disable LDP exact match on 10.10.10.2/32 and 10.10.10.4/32.
