Exam 350-801 topic 1 question 285 discussion

When a number is dialed, the Cisco Unified Communications Manager uses closest-match logic to select which pattern to match from among all the patterns in its call-routing table. In practice, when multiple potentially matching patterns are present, the destination pattern is chosen based on the following criteria: The pattern matches the dialed string. The pattern represents the smallest number of endpoints.

B&C When a number is dialed, the Cisco Unified Communications Manager uses closest-match logic to select which pattern to match from among all the patterns in its call-routing table.

Should be B and C according to this doc: https://www.ciscopress.com/articles/article.asp?p=3089358&seqNum=2 When a number is dialed, the Cisco Unified Communications Manager uses closest-match logic to select which pattern to match from among all the patterns in its call-routing table. In practice, when multiple potentially matching patterns are present, the destination pattern is chosen based on the following criteria: * The pattern matches the dialed string. * The pattern represents the smallest number of endpoints. They also provide an example: When a user dials the string 1210, then pattern 121X is chosen because out of the two potential matches, 121X and 12XX, 121X is the better match as it represents only 10 possible numbers while 12XX represents 100 possible numbers. I believe they use "numbers" and "endpoints" interchangeably, since an endpoint would have a number assigned to it.

B is clear correct, but the second answer is diffcult. It has nothing to do with the number of endpoints, so for me it is D. But maybe it is another misleading Question due to an unclear expression

BC Correct When a number is dialed, the Cisco Unified Communications Manager uses closest-match logic to select which pattern to match from among all the patterns in its call-routing table. In practice, when multiple potentially matching patterns are present, the destination pattern is chosen based on the following criteria: 1. The pattern matches the dialed string. 2. The pattern represents the smallest number of endpoints. https://www.ciscopress.com/articles/article.asp?p=3089358&seqNum=2

A is 100% wrong. B is 100% correct. I think C and E also Wrong, because the pattern match has nothing to do withe the Number of Endpoints. D should also be correct, but the shortest prefix? Maybe there is only one correct Answer.
