Refer to the exhibit. While configuring dial plan on a system, an engineer notices the route list in the pictured state. What will cause this?

Question

Exhibit

Options

• AOne subscriber server in CUCM Group is down
• B"No route group" is added in this Route List
• CMedia Resource on the CUCM are oversubscribed
• D"Run on all active unified CM nodes" is not checked on the route list

• A
  11% (4)
• B
  77% (27)
• C
  9% (3)
• D
  3% (1)

Explanation

In Cisco Unified Communications Manager, when a Route List entry is configured with 'No Route Group' (i.e., a route list detail entry exists but no route group is selected), CUCM displays a warning or error indicator on that route list. This is a misconfiguration because a route list must reference valid route groups to forward calls. The other options do not directly produce a visual error state on the route list itself: a subscriber server being down affects call processing but not the route list configuration display, oversubscribed media resources impact audio quality not routing config, and the 'Run on all active unified CM nodes' setting is on the route group, not the route list.
