You are writing the requirements for an MPLS L3VPN environment that uses MP-BGP between PE routers. In this environment, route targets and route distinguishers need to be advertised between the PE routers.
Which three operations meet these requirements? (Choose three.)

A. advertisement of standard communities, enabled on the PE-to-PE BGP neighbors

B. creation of PE-to-PE BGP sessions between loopback IP addresses

C. mandatory creation of PE-to-PE BGP sessions between the outgoing interface IP addresses

D. full mesh of EBGP sessions and partial mesh of IBGP sessions

E. advertisement of extended communities, enabled on the PE-to-PE BGP neighbors

F. full mesh of IBGP sessions

A network architect is troubleshooting the L2TPv3 tunneling security due to the untrusted nature of the underlaying network. Which two L2TPv3 features does the architect deploy to address the ongoing issues? (Choose two.)

A. CHAP authentication

B. asymmetric mutual authentication with PSK

C. control message rate limiting

D. control message hashing

E. TCP MD5 authentication

出題：7

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

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

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

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

出題：8

In MPLS Layer 3 VPN implementations, which mechanism is used to control which routes are imported to a VRF?

A. RT

B. VRF ID

C. RD

D. PW ID

E. VC ID

出題：9

What is the primary function of a VRF on a router?

A. It enables the router to support multiple separate routing tables, which allows the device to handle overlapping IP addresses.

B. It enables a router to run BGP and a distance vector routing protocol at the same time, which allows it to serve as a VPN endpoint between remote sites.

C. It enables a router to configure VLANs locally, which provides segregation between networks.

D. It enables the router to provide faster switching through the network by using labels to identify the input and output interfaces for neighbor routers.
