300-070 Question #257: Real Exam Question with Answer & Explanation

The correct answer is D: +61278259001. Breaking down the pattern: '\+' matches a literal '+', '61278' matches literally, '[^3-5]' is a negated character class matching any single digit NOT in the range 3 through 5 (so it matches 0, 1, 2, 6, 7, 8, or 9), '59' matches literally, and 'XXX' matches any three digits (0–9).

Question

Which pattern does the route pattern +61278[^3-5]59XXX match?

Options

A278259001
B+61278359001
C+61278459001
D+61278259001

Explanation

Breaking down the pattern: '+' matches a literal '+', '61278' matches literally, '[^3-5]' is a negated character class matching any single digit NOT in the range 3 through 5 (so it matches 0, 1, 2, 6, 7, 8, or 9), '59' matches literally, and 'XXX' matches any three digits (0–9). Option D (+61278259001) matches because '2' satisfies [^3-5]. Option C (+61278459001) fails because '4' is within the excluded range 3–5. Option B fails because '3' is also within the excluded range. Option A (278259001) fails because it is missing the required leading '+'.
