Your company has a main office and a branch office. The network contains two DNS servers named DNS1 and DNS2. DNS1 is located in the main office. DNS1 hosts a primary standard zone named contoso.com. The contoso.com zone is configured to use DNSSEC. DNS2 is located in the branch office. DNS2 is a caching-only DNS server.
