ICND2: Interconnecting Cisco Networking Devices Part 2 (legacy) — Question 43

Which command do you enter to enable an interface to support PPPoE on a client?

Answer options

• A. Dev1(config)# bba-group pppoe bba1
• B. Dev1(config-if)# pppoe-client dial-pool-number 1
• C. Dev1(config-if)# pppoe enable group bba1
• D. Dev1(config-if)# pppoe enable

Correct answer: D

Explanation

The command 'Dev1(config-if)# pppoe enable' directly activates PPPoE on the specified interface, making it the correct choice. The other options, while related to PPPoE configuration, do not specifically enable PPPoE on the interface itself. For instance, option A sets up a BBA group, and options B and C configure specific aspects of the PPPoE client but do not enable it.
