Zscaler Certified Technology Associate (ZDTA) — Question 76

Which three levels of inspection are used by Zscaler for File Type Identification?

Answer options

• A. Mime type, file extension and file size
• B. File extension, content type and file size
• C. Magic bytes, mime type and file extension
• D. Magic bytes, mime type and MS Office version

Correct answer: C

Explanation

The correct answer is C because Zscaler uses magic bytes to analyze the actual file content, along with mime type and file extension for accurate identification. Options A and B are incorrect as they do not include magic bytes, which are crucial for reliable file type determination. Option D introduces MS Office version, which is not part of the identification levels used by Zscaler.
