1. Which of the following is not added for IS-IS to support IPv6 route processing and calculation?
The source IP address of IS-IS Hello packets is changed to the link-local address.
TLV 232, which is equivalent to the IP Interface Address TLV in IPv4, except that the original 32-bit IPv4 address is changed to a 128-bit IPv6 address.

A) TLV 236, which describes network reachability by defining information such as route prefixes and metrics.
B) The NLPID value must be carried when IPv6 routes are advertised.

2. On the network shown in the figure , the network administrator deploys DHCP snooping on the switch to defend against bogus DHCP server attacks .

Which of the following interfaces should be configured as the DHCP trusted interface?

A) GE0/0/3
B) GE0/0/4
C) GE0/0/1
D) GE0/0/2

3. On the OSPF network shown in the figure, area 1 is a stub area, area 2 is a totally stub area, and area 3 is an NSSA . Which of the following routers are unable to import external routes ?

A) R4
B) R5
C) R3
D) R6

[R1] mpls
[R1-mpls] quit
[R1] mpls ldp
[R1-mpls-ldp] quit
[R1] interface gigabitethernet 0/0/1
[R1-GigabitEthernet0/0/1] mpls
[R1-GigabitEthernet0/0/1] quit

5. On the network shown in the figure, an administrator first completes the routing configuration and then enables MPLS and LDP on R1, R2, and R3 and their interconnected interfaces. In this manner, traffic from PC1 to PC2 can be forwarded based on MPLS . Which of the following routing configurations can implement this function?
