To configure a PPPoE client on MikroTik, you need to:
* Set the client interface (usually ether1 or another WAN-facing port).
* Optionally add NAT masquerading to enable LAN users to reach the internet.
* IP address on the interface is assigned dynamically from the ISP after PPPoE negotiation, so a static IP is not required.
Option Analysis:
* A.#Required - You must select the interface that initiates the PPPoE connection.
* B.#Not Required - The IP is typically assigned by the PPPoE server (ISP).
* C.#Required - NAT masquerade is commonly used to allow internet access for private IP clients behind the router.
Extract from MTCNA Course Material - PPPoE Client Setup:
"The PPPoE client must have an interface specified. A NAT masquerade rule is recommended for internet access sharing." Extract from Rene Meneses MTCNA Study Guide - PPPoE:
"You do not need to assign a static IP to the PPPoE client interface. IP is received after successful login." Extract from MikroTik Wiki - PPPoE Client:
"After setting up the interface and credentials, PPPoE client negotiates and receives dynamic IP. Add NAT if routing LAN traffic."
