210-065 Question #94: Real Exam Question with Answer & Explanation

The correct answer is A: A local call policy rule denied the call.. The Cisco TelePresence VCS search history logs each policy decision made during call processing, and in this case the log reveals a local call policy rule explicitly rejected the call before routing could complete.

Question

Refer to the exhibit. A technician is reviewing the search history details on a Cisco TelePresence VCS for a recent call that failed. What was the cause for the call setup failure?

Exhibit

Options

AA local call policy rule denied the call.
BThe source alias matched an entry in the registration deny list.
CThe originating caller was not authenticated.
DThe source alias origin is unknown.

Explanation

The Cisco TelePresence VCS search history logs each policy decision made during call processing, and in this case the log reveals a local call policy rule explicitly rejected the call before routing could complete.

Common mistakes.

B. A registration deny list blocks devices from registering with the VCS, not individual call attempts from already-registered or traversal endpoints.
C. Authentication failures produce a separate authentication challenge or rejection event in the search history, distinct from a policy-based denial.
D. An unknown source alias origin would indicate a routing lookup failure rather than an explicit call rejection issued by a policy rule.

Concept tested. Cisco VCS local call policy rule enforcement
