350-801 · Question #516

Refer to the exhibit. Which route pattern can the Cisco UCM administrator apply to the configuration to allow calls to "1306, 1316, 1326, 13*6, 13#6" only?

The correct answer is A. 13[^3-9]6. The correct route pattern to allow calls to the specified numbers is 13[^3-9]6, which uses a negated character range to include digits 0, 1, 2, and special characters like * and #. This pattern ensures only the desired numbers are matched.

Why each option

The correct route pattern to allow calls to the specified numbers is 13[^3-9]6, which uses a negated character range to include digits 0, 1, 2, and special characters like * and #. This pattern ensures only the desired numbers are matched.

A13[^3-9]6Correct

The [^3-9] component of the route pattern 13[^3-9]6 specifies that the character in that position must not be a digit from 3 through 9. This correctly allows digits 0, 1, 2 and also special characters like * and #, which are not numeric and therefore not in the specified excluded range, ensuring a match for all listed numbers.

B13[25-8]6

The pattern 13[25-8]6 would only match numbers where the third digit is 2, 5, 6, 7, or 8, failing to match numbers like 1306, 1316, 13*6, and 13#6.

C13!#

The pattern 13!# is too broad, matching 13 followed by one or more digits and then one or more digits/symbols, which does not precisely match the required fixed 6-character format with specific middle characters.

D13XX

The pattern 13XX only matches four-digit numbers starting with 13 and ending with any two digits, failing to match numbers containing '*' or '#' characters like 13*6 and 13#6.
