A. in all CE routers across a VPN community

B. in all PE and CE routers across a VPN community

C. in all PE routers across a VPN community

D. in all PE and CE routers within a VPN community

A. The peer router immediately removes the BGP routes that it learned from the restarting router from its BGP routing table.

B. The router establishes BGP sessions with other routers and relearns the BGP routes from other routers that are also capable of graceful restart. The restarting router waits to receive updates from the neighboring routers. When the neighboring routers send end-of- RIB messages to indicate that they are done sending updates, the restarting router starts sending its own updates.

C. The peer router sends an end-of RIB message to the restarting router.

D. The restarting router removes any stale prefixes after the timer for stale entries expires.

E. The restarting router does not remove any stale prefixes after the timer for stale entries expires.

A. periodically

B. never takes place

C. before switchover

D. during switchover

E. after switchover

A. The VPNv4 address is 96 bits long with a 64-bit long subnet mask.

B. The VPNv4 address consists of an RD and an IPv4 address.

C. The VPNv4 address is 128 bits long with a 64-bit long subnet mask.

D. The VPNv4 address is 96 bits long with a 32-bit long subnet mask

E. The VPNv4 address is 128 bits long with a 128-bit long subnet mask

F. The VPNv4 address consists of an RT and an IPv4 address.

A. There is no autodiscovery.

B. CDP is not required on the PE routers.

C. BGP does not need to be run on the PE device.

D. LDP signaling requires a loopback-based router ID.

E. Non-convergence with IP VPN operation.

A. GetBulk messages are converted to GetNext messages by the proxy agent and are then forwarded to the SNMP version 1 agent.

B. SNMP version 2 uses a proxy agent to forward GetNext message to SNMP version 3.

C. SNMP version 2 supports message integrity to ensure that a packet has not been tampered with in transit.

D. SNMP version 3 supports encryption and SNMP version 2 support authentication.

E. Proxy agents were used only in SNMP version 1.

A. Anycast

B. MPLS node protection

C. IP Fast Reroute

D. IP SLA

A. CoPP supports rate limits; Racl does not support rate limits

B. CoPP can not use named access lists; Racl can use named access lists

C. CoPP applies to a dedicated control plane interface; Racl applies to all interfaces.

D. CoPP needs a AAA server, Racl does not need a AAA server

E. CoPP protects against IP spoofing; Racl protects against DoS attacks.

A. at least four

B. at least three

C. at least one

D. at least two

E. zero

A. In Cisco VPLS the virtual circuit setup uses the same LDP signaling mechanism defined for point-to-point services. Using a directed LDP session, each provider edge advertises a virtual circuit label mapping that is used as part of the label stack imposed on the Ethernet frames by the ingress provider edge during packet forwarding.

B. Cisco VPLS uses directed LDP as a signalling protocol to exchange reachability (MAC addresses) information to avoid maintanance of ARP cache.

C. Cisco VPLS does not require the exchange of reachability (MAC addresses) information via a signaling protocol. This information is learned from the data plane using standard address learning, aging, and filtering mechanisms defined for Ethernet bridging.

D. In Cisco VPLS the virtual circuit setup uses Multi-Protocol BGP as autodiscovery and signaling mechanism.
Using BGP allows BPDUs to be propagated across VPLS in a scaleable fashion.

B. MLD querier

C. MLD snooping

D. IGMP version 3

E. IGMP snooping

A. Change the framing type on the router POS interface.

B. Swap the POS interface.

C. Reset the POS interface.

D. Check the ADM switch for correct framing.
