Certified SOC Analyst (CSA) — Question 27

Which encoding replaces unusual ASCII characters with "%" followed by the character’s two-digit ASCII code expressed in hexadecimal?

Answer options

• A. Unicode Encoding
• B. UTF Encoding
• C. Base64 Encoding
• D. URL Encoding

Correct answer: D

Explanation

The correct answer is URL Encoding, as it is specifically designed to encode characters in URLs by replacing non-ASCII characters with a '%' and their hexadecimal ASCII value. The other options, such as Unicode Encoding and UTF Encoding, relate to different character encoding systems, while Base64 Encoding is used for binary data representation, not for encoding ASCII characters in URLs.
