Q

You are nearing the completion of an upgrade that involves implementing a new network infrastructure and upgrading the OS running on your network servers.

Currently, static IP address and HOSTS files are used. The upgrade has included implementing DNS, DHCP, and moving servers and other resources to a new location with a new IP address.

You cannot access the resources that were moved using their host names from any of the client workstations.

You CAN access them by their IP address.

What should you do first?

A

Delete the HOSTS file on each workstation.

Workstations read entries in their HOSTS files before making requests to DNS.
