Free CompTIA Network+ N10-008 Practice Question

A midsize company has recently begun to experience increased latency and unexpected redirection of web traffic affecting several users. The network administrator suspects a DNS poisoning attack. What initial action should the administrator take to confirm and respond to this suspected security breach?

  • Clear the DNS cache on the company's primary DNS server to remove any potentially malicious entries.

  • Change the DNS resolver settings on an affected user's machine to a reputable public DNS server and compare the resolution results.

  • Install additional DNS servers to handle user requests and prevent overloading a single server that might be causing the issues.

  • Check for pending software updates for all network devices and user endpoints to ensure they have the latest security patches.
