Question:1 Select the 3 best answers describing operation and configuration of Frame-Relay Inverse ARP. A. Dynamic address mapping uses Frame Relay Inverse ARP to request the next-hop protocol address for a specific

connection on its known DLCI. B. Responses to Inverse ARP requests are entered in an address-to-DLCI mapping table on the router or access server

which is used to supply the next-hop protoco address or the DLCI for outgoing traffic C. Inverse ARP is enabled by default for all protocols enabled on the physical interface. D. Inverse ARP is configured using the following command under the Interface configuration ‘frame-relay map dlci

(dlci number) protocol protocol-address’. E. Inverse ARP in Frame-Relay is synonymous of ARP in Ethernet.

Answer: A, B, C Question:2 Select the three valid LMI extension A. Multicasting B. Global addressing C. Forward-explicit congestion notification (FECN) D. Virtual circuit status messages. E. Backward-explicit congestion notification (BECN)

Answer: A, B, D Question:3 Which two statements regarding the IS-IS DIS election process are true? (Choose Two.) A. A priority of 0 will prevent a router from becoming a DIS. B. If the DIS becomes unavailable the backup DIS is promoted to DIS. C. Adding a router with a higher priority than the current DIS will result in the new router becoming DIS. D. Separate L1 and L2 election processes are held on a broadcast network. E. L1 routers on a broadcast network only establish adjacencies with the DIS. F. If there is a tie based on priority, the router whose attached interface has the lowest MAC address becomes the DIS.

None of the above will alter Differentiated Services (Diff-Serv) code points set in different Differentiated Services

(Diff-Serv) domain Answer: A Question:6 What is jitter? A. The total end-to-end delay B. The variations of delay. C. The delay caused by placing the bits on the wire. D. The time it takes for the bits to transit the physical media.
