Thanks, Steve. I understand the virtual link authentication, but the
real question here is .... if the question asks for area 0
authentication link....then, should we also assume virtual link
authentication (since a virtual link is the extension of the area 0.
Or, is the virtual link considered a completely different area as it
applies to authentication?

authentication???
You can put the authentication right in the virtual-link statement:
router ospf 10
area 0 authentication message-digest
area 3 authentication message-digest
area 4 authentication message-digest
area 4 virtual-link 10.6.6.6 message-digest-key 1 md5 cisco
In this example from this router is ABR in 3 & 4 with no connection to
area 0 except the virtual link and the lab requires authentication on
all links.
