350-801 Question #538: Real Exam Question with Answer & Explanation

Question

An engineer must configure a new Cisco UCM route pattern. When a user at extension 5555 and external phone number mask XXXX dials 911 or 9911, these requirements must be met: - Both patterns must be accepted. - Only the number 911 must be sent to the gateway. - A caller ID of 555-555-5555 must be sent to the gateway. - All transformations must be done at the route pattern level. Which two route patterns must be used? (Choose two.)

Options

• ARoute pattern: 9.@
• BRoute pattern: 9.@
• CRoute pattern: 911 -
• DRoute pattern: 911 -
• ERoute pattern: 9.911 -

Explanation

To accept both 911 and 9911, send only 911 to the gateway, and set the caller ID to 555-555-5555, two route patterns are required: one for an exact 911 match and another using a wildcard for 9911 with appropriate transformation masks.

Common mistakes.

• B. While Route pattern: 9911 would precisely match the 9911 dial string, the combination of A and D is specified as correct, implying a broader matching pattern 9.11 is considered for 9911 in this context.
• C. The route pattern 911 - would match 911 and any longer numbers starting with 911, but it would not match 9911, thus failing to meet the requirement to accept both 911 and 9911.
• E. The route pattern 9.911 - would match five-digit numbers like 90911 through 99911 and strip off digits after the 9.911 part, which is incorrect for matching either 911 or 9911.
