Your company's network frequently faces problems with clients being unable to access websites by name using the primary name resolution server, set to query other servers for this information if it doesn't already have it. What is the most likely cause of these connectivity problems?
The name resolution server can't reach external servers because of incorrect firewall configurations
The connectivity issues stem from having the caching feature disabled on the name resolution server
The presence of a rogue configuration protocol server is disrupting name query processes
Security protocols on domain querying were activated, blocking all external name requests
