During the name resolution process, which technique is used to avoid congestion when querying a server

"NOT lookup " is the correct approach.

Explanation:

This methodology significantly reduces the quantity of congestion of DNS messages on a certain file. The application establishes that whenever a question reaches if it is processed. Unless the file is loaded, then perhaps the response is returned with the cached cache.Typically the name resolution occurs in something like a DNS File. The conversion usually occurs throughout this cycle from Username to IP, including IP via Username.
