Question 1

Which two statements best describe the signalling requirements of virtual circuit setup of VPLS and exchange of reachability information (MAC addresses)?

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

Question 2

You applied this ACL to the interface and several people reported that they were unable to access the network.
ipv6 access-list webOnly
permit tcp any 2001:DB8::/32
permit udp any 2001:DB8::/32
deny ipv6 any any
Which answer explains why they were unable to access the network?

A. The connections are stale. The users must close and restart their applications. B. DNS queries and replies are not working. C. DHCP requests are not reaching to the DHCP server. D. The ACL is blocking the operation of the ND process.

Question 8

Refer to the Exhibit,R1 and R5 router are not directly connected loopback 0 is configured as LDP router-id for both R1 and R5 router loopback IPV4 address are reachable between R1 and R5 router. The LDP session between R1 and R5 is not established. There is no access-list applied any router in the path between R1 and R5,which is the reason the LDP session is not working?

A. The LDP ID must be the physical interface of the interface tunnel between the LDP neighbor B. LDP authentication is missing on both R1 and R5 C. R5 is not configured to accept targeted LDP sessions D. Targeted LDP works only for directly connected LDP neighbors
