QUESTION 482

In inter-AS multicast, which two optional nontransitive path attributes were introduced in BGP to carry unicast and multicast routing information for RPF check at the AS borders? (Choose two.)

 

A.

MP_UNREACH_NLRI

B.

MP_REACH_NLRI

C.

FWDR_PREF Details

D.

MP_PERF_NLRI

E.

ORIGINATOR_ID

 

Correct Answer: AB

 

 

QUESTION 483

Which three options are restrictions for MPLS VPN BGP Local Convergence? (Choose three.)

 

A.

The MPLS VPN BGP Local Convergence feature affects only traffic that is exiting the VPN. Therefore, it cannot fully protect traffic end-to-end by itself.

B.

This link protection can be initiated during a HA SSO. But links that were configured with this protection before the switchover begins remain protected after the switchover.

C.

The MPLS VPN BGP Local Convergence feature for IPv4/IPV6 supports the eBGP, RIP, EIGRP,OSPF, and dynamic routing protocols.

D.

Any next-hop core tunneling technology that is supported by BGP is also supported for protection, including MPLS, L2TPv3, and IP/GRE. CSC protocol between the PE and CE is also supported. Interautonomous system option A (back-to-back VRF) is supported because it is essentially the same as performing the PE-CE link protection in both autonomous systems. However, interautonomous system options B and C protection are not supported.

E.

If you perform an in-service software downgrade from an image that does include this link protection to an image that does not support this feature, active protection is halted when BGP routes are refreshed.

 

Correct Answer: ADE

 

 

QUESTION 484

Which command will display the MPLS label binding for IP prefix 1.1.1.0 on the router?

 

A.

All of the above.

B.

C.

show tag-switching tdp bindings neighbor 1.1.1.0

D.

A and B both will show the binding.

E.

show tag-switching interface e0/0

 

Correct Answer: B

 

 

QUESTION 485

A security risk has been discovered on the Service Provider MPLS core network during a network audit. Traceroute between the customer sites displays IP addresses of the Service Provider MPLS core. What should be done to hide the IP addresses of the Service Provider MPLS core from the customer traceroute utility?

 

A.

Configure an access list to block traceroute traffic.

B.

Apply the no mpls ip propagate-ttl forward command.

C.

Enable MPLS LDP session protection.

D.

Configure an LDP label allocation filter.

E.

Apply the no mpls ip propagate-ttl local command.

 

Correct Answer: B

A.

route-policy

B.

access-list

C.

distribute-list

D.

policy-map

 

Correct Answer: C
