A. B. C. D. E.Explanation.
Sure, I'd be happy to provide a detailed explanation!
In Cisco Unified Communications Manager (CUCM), route patterns are used to define how calls are routed within the system. When a user dials a number, CUCM uses route patterns to determine how to route the call to its destination.
In this question, the user is dialing the number "2001", and we need to determine which route pattern will be matched in CUCM version 11.0.
Let's take a look at each of the answer choices:
A. 200X configured with urgent priority This route pattern would match any four-digit number that starts with "200", followed by any digit. The "X" wildcard matches any digit. The "urgent priority" setting means that if this route pattern is matched, the call will be immediately routed without waiting for any other potential matches. However, this route pattern does not match the specific number "2001", so it is not the correct answer.
B. 20[02-4]1 configured with urgent priority This route pattern would match any four-digit number that starts with "20", followed by a digit between 0 and 4, followed by a "1". The brackets indicate a range of possible digits, and the "-" indicates a range of sequential digits. The "urgent priority" setting means that if this route pattern is matched, the call will be immediately routed without waiting for any other potential matches. This route pattern does match the specific number "2001", so it is a possible correct answer.
C. 200[1-4] configured with urgent priority This route pattern would match any four-digit number that starts with "200", followed by a digit between 1 and 4. The "urgent priority" setting means that if this route pattern is matched, the call will be immediately routed without waiting for any other potential matches. This route pattern does match the specific number "2001", so it is a possible correct answer.
D. 200[^2-4] configured with urgent priority This route pattern would match any four-digit number that starts with "200", followed by any digit except 2, 3, or 4. The "^" indicates negation, meaning any digit that is not in the specified range. The "urgent priority" setting means that if this route pattern is matched, the call will be immediately routed without waiting for any other potential matches. However, this route pattern does not match the specific number "2001", so it is not the correct answer.
E. 200! configured with urgent priority This route pattern would match any four-digit number that starts with "200". The "!" wildcard matches one or more digits. The "urgent priority" setting means that if this route pattern is matched, the call will be immediately routed without waiting for any other potential matches. However, this route pattern does not match the specific number "2001", so it is not the correct answer.
Based on the above analysis, answer choices B and C are both possible correct answers. It's difficult to determine which one is the definitive correct answer without more information about the configuration of the CUCM system.
