Which utility can a Citrix Administrator use to resolve frequently looked up DNS requests?

• A. nslookup
• B. curl 'K 'd
• C. ping
• D. dig +trace

Answer: (D)

When you want to understand how a DNS name is resolved and why it’s being looked up repeatedly, you need visibility into the entire lookup path. Dig with the +trace option shows the step-by-step resolution starting from the root servers, then the TLD servers, and finally the authoritative servers, so you can see exactly where each part of the query is coming from and where any delays or caching issues occur. The other tools either perform a simple query or test connectivity without exposing that full resolution path, so they don’t offer the same diagnostic visibility.
