A. B. C. D. E.E
The correct answer is C. 102 is the remote DLCI that will receive the information.
Explanation:
The command frame-relay map ip 10.121.16.8 102 broadcast is used to map an IP address to a specific Data Link Connection Identifier (DLCI) on a Frame Relay network. In this case, the IP address 10.121.16.8 is being mapped to the DLCI 102, which means that any packets destined for that IP address will be sent over the Frame Relay connection using the DLCI 102.
Let's break down the command:
frame-relay: This command puts the router into Frame Relay configuration mode.map: This command is used to map an IP address to a DLCI.ip 10.121.16.8: This specifies the IP address that is being mapped.102: This is the DLCI that the IP address is being mapped to.broadcast: This option allows broadcast packets to be forwarded across the PVC.Option A, "This command should be executed from the global configuration mode," is incorrect. The command should be executed from the Frame Relay configuration mode.
Option B, "The IP address 10.121.16.8 is the local router port used to forward data," is incorrect. The IP address is being mapped to a DLCI, not a router port.
Option D, "This command is required for all Frame Relay configurations," is incorrect. The command is not required for all Frame Relay configurations, but it is commonly used to map IP addresses to DLCIs.
Option E, "The broadcast option allows packets, such as RIP updates, to be forwarded across the PVC," is partially correct. The broadcast option does allow broadcast packets to be forwarded across the PVC, but it is not the primary purpose of the frame-relay map command. Its primary purpose is to map IP addresses to DLCIs.
