When a newly installed system for synchronizing passwords across multiple systems and platforms abnormally
terminates without warning, which of the following should automatically occur FIRST?

A.
The firewall should block all inbound traffic during the outage

B.
All systems should block new logins until the problem is corrected

C.
Access control should fall back to no synchronized mode

D.
System logs should record all user activity for later analysis

Explanation:

The best mechanism is for the system to fallback to the original process of logging on individually to each system. Blocking traffic and new logins would be overly restrictive to the conduct of business, while recording all user activity would add little value.
