Have you actually tried this? It takes all of about 10 seconds to answer
this question yourself... In any case, yes, Asterisk will know that all
the B channels went into alarm, and if a PRI is in use on that span,
that the D channel also went into alarm. It does not have a concept of a
'span' though.

I don't believe there is currently an AMI event generated for Zap
channel alarms, but it would certainly be trivial to add one.
