  1. HSRP might be right but that doesn’t mean also that local preference is wrong for outbound traffic.

    1. Not wrong. It’s one of those questions…

      If this is a BGP related question I’d go with
      A, as the AS PATH can be used to influence where the remote AS will deliver traffic to the local AS. If that device fails there’s always the other inbound option.

      For outbound, local preference can be used to select preferred outgoing path, but then again weight is also an option, and this is a Cisco exam, so…

      Not sure.

  2. I think that correct answer is AD. HSRP for LAN interface, AS path for WAN interface. We have dual homing with the same solution.
