Which statement describes Dig's DNS capabilities?

• A. It is used to compress files.
• B. It is used to query DNS servers and can perform zone transfers.
• C. It is a wireless diagnostic tool.
• D. It is used to route traffic.

Answer: (B)

Dig is the DNS lookup utility used to query DNS servers and retrieve information about domain names. It can request zone transfers, meaning it can obtain the entire zone data from a DNS server if the server allows it. This combination—querying DNS servers and, when permitted, performing zone transfers—is exactly what Dig is designed to do. The other options describe tasks outside the scope of a DNS query tool: compressing files, wireless diagnostics, or routing traffic. Therefore, describing Dig as a tool to query DNS servers and perform zone transfers best reflects its capabilities.
