Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) — Question 262

What matches the regular expression c(rgr)+e?

Answer options

• A. c(rgr)e
• B. crgrrgre
• C. crgr+e
• D. ce

Correct answer: B

Explanation

The correct answer is B, as it contains the substring 'rgr' repeated at least once, followed by 'e', which matches the pattern. Option A has 'c(rgr)e', but it does not repeat 'rgr', and options C and D either lack the necessary repetitions or do not conform to the expected format.
