Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) — Question 272

What matches the regular expression r(ege)+x?

Answer options

• A. r(ege)x
• B. regeegex
• C. rx
• D. rege+x

Correct answer: B

Explanation

The correct answer is B, as it contains the sequence 'rege' repeated at least once followed by 'x', which matches the pattern. Option A does not have 'e' repeated, C lacks the necessary sequence entirely, and D has 'e' repeated but does not correctly follow the pattern defined by the regular expression.
