Question # 82

OSPF router R2 has both point-to-point and broadcast interfaces and it is not a DR for any interfaces. Router R2 detects the link failure between itself and router R1.

Which of the following is correct?

Options:

Router R2 sends an update to 224.0.0.5 on its broadcast and point-to-point interfaces. The DR does not send any updates.

Router R2 sends an update to 244.0.0.5 on its point-to-point interfaces. The DR sends an update to 224.0.0.6 on the broadcast network.

Router R2 sends an update to 224.0.0.5 out its point-to-point interfaces and an update to 224.0.0.6 out its broadcast interface. The DR sends updates to 224.0.0.5 on the broadcast network.

Router R2 sends an update to 224.0.0.6 out its point-to-point interfaces and an update to 224.0.0.5 out its broadcast interface. The DR sends an update to 224.0.0.6 on the broadcast networks.

Options:

Configure the T-LDP peers for tunneling.

Configure tunneled T-LDP sessions between PE routers.

Enable Idp-over-rsvp in the IGP configuration on the PEs and ABRs

Enable LSP stitching on the RSVP LSPs

Questions # 84:

Which of the following reservation styles can be used to prevent both the primary and secondary paths from booking resources on a common link?

Options:

Fixed filter

Shared explicit

Standby explicit LSP

Preemptive filter

Link capacity filter

Questions # 85:

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

Options:

Static LSPs

Reserved use

Vendor proprietary use

Management LSPs

Dynamic LSPs

Questions # 86:

Which of the following best describes the actions taken by an IS-IS router after it receives an LSP on a broadcast interface that is newer than the one in its database?

Options:

The router sends a copy of the LSP from its database to its neighbor.

The router updates its database with the LSP and floods a copy to its other neighbors.

The router updates its database with the LSP, acknowledges the LSP with a PSNP and floods a copy to its other neighbors.

The router updates its database with the LSP and acknowledges it with a PSNP.

Question # 88

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?

Options:

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

Question # 89

OSPF is operational on all links in the network diagram, all routers are the same cost, and all routers are configured with an ECMP value of 4. Router R5 advertises the prefix 192.168.3.0/24 into OSPF.

How many entries for prefix 192.168.3.0/24 will be in router R3's routing table?

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

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

Questions # 91:

When IS-IS is electing a DIS, what is used as the tie breaker on an Alcatel-Lucent 7750 SR, if the priorities are the same?

Options:

The system ID

The loopback address

The sequence number of the Hello packet

The device that first initiated communication becomes the DIS

The highest interface MAC address

Question # 92

Examine the physical topology of the IS-IS network, the metrics of the links and the levels of the routers. All routers have a system address included in IS-IS.

Which of the following describes the route that router R4 will use to reach the system address of router R6?

Options:

Router R4 will have a route to router R6's system address with router R2 as the next-hop.

Router R4 will have a default route with router R2 as the next-hop.

Router R4 will have a default route with router R3 as the next-hop.

Router R4 will not have a route to router R6's system address, nor will it have a default route.

Questions # 93:

On a point-to-point link, two directly connected routers set different interface hello timeout values. Router R1 uses 15 seconds, while router R2 uses 30 seconds. What happens to the LDP adjacency?

Options:

The adjacency forms with the lower timeout value

The "show router Idp session" command output displays the adjacency in state "init"

The adjacency forms with the higher timeout value
