B. LSAs are sent over a TCP connection.

C. LSAs are acknowledged by the neighboring router.

D. LSAs are advertised with an acknowledgement bit.

D. Type 5

You must provide network connectivity to hosts that fail authentication.

In this scenario, what would be used in a network secured with 802.1X to satisfy this requirement?

C. If wide-metrics-only is configured, Level 1 routes are not advertised to Level 2 routers by default.

D. Level 1 routes advertised as external routes into Level 1 are not advertised to any Level 2 routers by default.
