Palo Alto Networks Network Security Generalist — Question 16

What is the primary role of Advanced DNS Security in protecting against DNS-based threats?

Answer options

• A. It replaces traditional DNS servers with more reliable and secure ones.
• B. It centralizes all DNS management and simplifies policy creation.
• C. It automatically redirects all DNS traffic through encrypted tunnels.
• D. It uses machine learning (ML) to detect and block malicious domains in real-time.

Correct answer: D

Explanation

The correct answer is D because Advanced DNS Security utilizes machine learning algorithms to analyze DNS queries in real-time, allowing it to identify and block malicious domains effectively. Options A and B do not address the specific function of threat detection, while C refers to traffic encryption rather than active malicious domain blocking.
