CompTIA Network+ N10-009 Practice Question

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?

  • Security protocols on domain querying were activated, blocking all external name requests

  • The name resolution server can't reach external servers because of incorrect firewall configurations

  • The presence of a rogue configuration protocol server is disrupting name query processes

  • The connectivity issues stem from having the caching feature disabled on the name resolution server
