Question 1
A county purchases dispatch connectivity from two carriers. Separate failover tests succeed when either carrier is disconnected. During nearby road excavation, however, both connections fail together. The dispatch center retains power, and both carriers report that their regional networks are operating. Before crediting the two contracts as independent protection, which dependency deserves investigation first?
Show answer & explanation
Correct answer: A - A shared physical route for the carriers' connections to the dispatch center.
