Which two types of LSAs have a domain scope? (Choose two.)

Type 7
Type 2
Type 10
Type 5

Correct answer: CD

Which authentication strategy authenticates IS-IS hello PDUs only?

interface authentication
area authentication
domain authentication
level authentication

Correct answer: D

Explanation:

R5 must advertise Subnet A into IS-IS so that Subnet A and Subnet B can communicate. Subnet B must be able to forward traffic to Subnet A and towards Area 49.0001. However, R5 should not be able to route traffic from Subnet A to Area 49.0001.

Referring to the exhibit, how would you solve this problem?

Configure Level 2 on all links in Area 49.0002.
Configure the set protocols isis ignore-attached-bit parameter on R5.
Configure the set protocols isis overload parameter on R6.
Configure an export policy on R6 to reject all routes except Subnet B towards R5.

Correct answer: B

Referring to the exhibit, RR1-RR4 are route reflectors.

Which three routers would RR1 need to peer with if the no-client-reflect parameter has been configured? (Choose three.)

Correct answer: ACE

In a carrier-of-carrier VPN model, which type of network layer reachability information is used for the MP-BGP signaling between CE and PE routers?

unicast
inet-vpn

Correct answer: D

Explanation:

In a Carrier-of-Carrier VPN environment, specify the inet-vpn address family and unicast traffic type to enable BGP to carry IPv4 network layer reachability information (NLRI) for VPN routes.
