What is the correct command to configure a PPPoE client to obtain a session over an Ethernet interface?

• A. /interface pppoe-client add name=PPPoE interface=ether1 user=USER password=PASS add-default-route=yes use-peer-dns=yes
• B. /interface pppoe-client add name=PPPoE interface=ether1 user=USER
• C. /interface pppoe-client add name=PPPoE interface=ether2 user=USER password=PASS
• D. /interface pppoe-client add name=PPPoE interface=ether1 user=USER password=PASS add-default-route=no use-peer-dns=yes

Answer: (A)

Binding a PPPoE session to a specific Ethernet interface and pulling in routing and DNS from the PPPoE server is what this command does. It creates a PPPoE client on the chosen Ethernet port (the one that will carry the session), supplies the authentication credentials (user and password), and enables the router to automatically use the PPPoE-provided default route and DNS servers. This ensures proper connectivity as soon as the session comes up. Using the correct interface is crucial; pointing to a different NIC would place the session elsewhere and DNS or routing would not be set up automatically. Omitting the default route or DNS options would require manual configuration later, which is why including add-default-route=yes and use-peer-dns=yes makes this the best choice.
