B. Layer 2 VPNs use AToM, but Layer 3 VPNs use MPLS/BGP.

C. Layer 2 VPNs use BGP, but Layer 3 VPNs use VPLS.

D. Layer 2 VPNs use L2TPv3 tunneling, but Layer 3 VPNs use GRE tunneling.

E. Layer 2 VPNs use IPsec tunneling, but Layer 3 VPNs use pseudowires to provide tunneling.

Refer to the exhibit. If the two devices are operating normally, which two conclusions can you draw from this configuration? (Choose two.)

A. CE1 must use OSPF to establish a neighbor relationship with PE1.

B. PE1 labels the routes it learns from CE1 with the route-target 222:2 and shares them with its VPNv4 peers.

C. PE1 labels the routes it learns from CE1 with the route-target 111:1 and shares them with its VPNv4 peers.

D. The PE-CE routes between the devices are being exchanged by OSPF

E. CE1 is supporting CSC.

A. TCP MD5 authentication

B. control message hashing

C. CHAP authentication

D. control message rate limiting

Which two statements about MPLS L3 VPN RDs are true? (Choose two.)

A. They enable EIGRP to use address families to separate traffic between IPv4 and VPNv4.

B. They are represented as 32-bit values

C. They are represented as 64-bit values.

D. They enable OSPF to import and export routes into the global routing table of a router.

E. They allow BGP to uniquely identify duplicate routes.

A. Prefixes that are received with route targets and distinguisher are accepted.

B. Prefixes that are received with route targets and distinguisher are not accepted.

C. Prefixes that are received with route targets that are not imported at the PE are not accepted.

D. Prefixes that are received with route targets that are not imported at the PE are accepted.

Refer to the exhibit. A technician is troubleshooting a connectivity issue and notices that there is no IS-IS adjacency between R1 and R2. What can the technician change to bring the IS-IS adjacency up?

A. Change R2's net address to be in the same area as R1.

B. Change R1's is-type to level-2-only

C. Change R1's net address to be in the same area as R2.

D. Change R2's configuration to no longer set the overload bit.

Refer to the exhibit:

A network engineer is implementing an OSPF configuration Based on the output, which statement is true?

A. In the ospfv3 1 area 1 ipv4 command, area 0 must be configured instead of area 1.

B. OSPFv3 does not run for IPv4 on FastEthemet0/0 until IPv6 routing is enabled on the router and IPv6 is enabled on interface Fastfc.thernet0/0

C. OSPFv3 cannot be configured for IPv4; OSPFv3 works only for IPv6.

D. IPv6 routing not enabled" is just an informational message and OSPFv3 runs for IPv4 on interface FastEthernet0/0 anyway

Refer to the exhibit.

A. Disable spanning tree to allow loops to occur within the hub-and-spoke topology.

B. Disable split horizon to allow multiple VCs per spoke

C. Disable Cisco Discovery Protocol to allow MPLS to share labels between the designated spokes

D. Disable Cisco Discovery Protocol to allow for neighbor discovery

Refer to the exhibit.
