Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 200

A network engineer is configuring a routed interface to forward broadcasts of UDP 69, 53, and 49 to 172.20.14.225. Which command should be applied to the configuration to allow this?

Answer options

• A. router(config-if)#ip helper-address 172.20.14.225
• B. router(config-if)#udp helper-address 172.20.14.225
• C. router(config-if)#ipudp helper-address 172.20.14.225

Correct answer:

Explanation

The correct command is 'router(config-if)#ip helper-address 172.20.14.225', which is used to forward broadcast packets for specific UDP ports to a designated address. Options B and C are incorrect as they do not use the proper syntax for the command, making them invalid for this configuration.
