Which utility focuses on capturing and analyzing DNS queries generated by applications?

• A. APIs
• B. PA File Sight
• C. Heuristic Analysis
• D. DNSQuerySniffer

Answer: (D)

Capturing and analyzing DNS queries generated by applications is about monitoring the specific DNS traffic that applications generate. DNSQuerySniffer is designed for this purpose: it focuses on logging DNS query events, including which domain names are being resolved and, often, which process or application initiated the query. This makes it a direct fit for understanding how apps interact with DNS, spotting suspicious lookups, and troubleshooting DNS-related issues. The other options don’t fit as closely. APIs are general interfaces for software communication, not a DNS-monitoring tool. Heuristic analysis is a method for detecting suspicious behavior by analyzing patterns, not a tool that captures DNS queries. PA File Sight is a file-monitoring utility that tracks changes to files on the system, not network DNS activity.
