ServiceNow Certified Implementation Specialist – Service Mapping — Question 1

Which one of the following best represents the output from the following Regular Expression?
([\w\d\-\.]+)

Answer options

• A. Match a single character in the list between one and unlimited times.
• B. Match a single character in the list one time.
• C. Match a single character in the list between one and three times.
• D. Match a single character in the list between one and ten times.

Correct answer: A

Explanation

The correct answer is A because the '+' quantifier in the Regular Expression indicates that the preceding character set can match one or more times, which can be unlimited. Options B, C, and D are incorrect as they restrict the number of matches to a specific count, which does not reflect the behavior of the '+' quantifier.
