You manage a network with two locations: Denver and Phoenix. Both sites are connected with a WAN link. The network uses westsim.private as the domain name. The DNS1 server is located in the Denver location and has the primary copy for the westsim.private zone. The DNS2 server is located in Phoenix and is a secondary server for the zone. You notice that as you add new A records to the zone, users in Phoenix are unable to resolve the hostname for the new host for up to 15 minutes after the record has been added. You want to reduce this time so that hostnames can be resolved in Phoenix as soon as possible. What should you do?
