You have obtained an ADSL circuit at a remote office for central office connectivity. What will you need to configure on the remote office router?

Asymmetrical Digital Subscriber Line (ADSL) connectivity typically uses PPPoE to authenticate subscribers. The subscriber's credentials are often relayed to a RADIUS server for subscription checks. Metro Ethernet is a WAN connectivity method and not a protocol that is used with ADSL. PPP does not need to be configured for use over an ADSL connection, but the authentication portion of PPPoE must be configured. MPLS is a WAN connectivity method and not a protocol that is used with ADSL.
