Question # 81

Refer to the exhibit. A network engineer with an employee ID 4379:43:595 is setting up an IS-IS network with these requirements:

  • Routes with a tag of 80 and IP prefixes other than 192.168.10.20/24 must be redistributed from Level 1 into Level 2.
  • Route leaking must be configured from Level 2 into the Level 1 domain for routes that are tagged with only 50 or 40.

Which configuration must be implemented on RB to meet the requirements?

A.

Add match tag 80 in route-map Ieak2-1

B.

DUMPS Add match ip address 152 in route-map redist1-2

C.

Remove match tag 40 from route-map Ieak2-1

D.

Change match tag 80 to match tag 50 in route-map redist1-2.

C.

creating a bypass LSP for each protected LSP at each point of local repair

Question # 84

The network-engineering team of a service provider is integrating several recently acquired networks into a more scalable common Unified MPLS architecture. The new network architecture will support end-to-end VPNv4 and VPNv6 services with these requirements:

• The IGP of the core layer is IS-IS In Area 0.

• The IGP of the aggregation layers is OSPF in Area 0.

• The LDP protocol Is used to distribute label bindings within each IGP domain.

Which task must the network engineer perform when implementing this new architecture?

A.

Configure BGP-LU between ABR routers of each IGP domain to carry MPLS label information in NLRI.

B.

Configure a BGP session between the ABR routers of each IGP domain to exchange VPNv4 or VPNv6 prefixes

C.

Configure the ABR in each IGP domain to preserve next-hop information on all VPNv4 and VPNv6 prefixes advertised by the PE.

D.

Configure mutual redistribution of each IGP domain's loopback prefix to provide end-to-end LDP LSP

Question # 85

Refer to the exhibit:

What is the effect of this configuration?

A.

The two routers fail to form a neighbor relationship because their system IDs are different.

B.

The two routers successfully form a neighbor relationship

C.

The two routers fail to form a neighbor relationship because the authentication configuration is missing

D.

The two routers fail to form a neighbor relationship because they have different ISIS area types.

B.

Add a community string to the existing entry

C.

Re-configure to use SNMPv3.
