Question

Which utility can a Citrix Administrator use to resolve the Domain Name System (DNS) request being looked up frequently?

A. nslookup
B. dig +trace
C. curl ג€”K ג€”d
D. ping

Answer

A. nslookup

Explanation

nslookup is a command-line utility used to query the Domain Name System (DNS) to obtain domain name or IP address mapping or other DNS records. It is the most suitable tool for resolving issues related to frequent DNS lookups in a Citrix environment.

When a Citrix administrator encounters a situation where DNS requests are being looked up frequently, using nslookup can help identify the cause of the issue. By running nslookup, the administrator can:

  1. Verify if the DNS server is responding correctly
  2. Check if the DNS records are properly configured
  3. Determine if there are any discrepancies between the DNS server and the client’s local DNS cache

The other options mentioned are not as effective for resolving frequent DNS lookups:

  • dig +trace: This command is used to trace the delegation path of a DNS query, but it does not provide detailed information about the DNS server’s response or the client’s local DNS cache.
  • curl -K -d: curl is a tool for transferring data using various protocols, but it is not specifically designed for diagnosing DNS-related issues.
  • ping: This utility is used to test the reachability of a host and measure the round-trip time for messages sent from the originating host to a destination host. While ping can help determine if a host is reachable, it does not provide detailed information about DNS lookups.
