impractical, so the solution is to make the 7190s authoritative for a
zone within the mstd-ex.com domain, rather than for the entire
domain. For this example the authoritative name server for the mstd-
ex.com domain delegates authority of a new zone within its domain
to the 7190. This zone is called geo.mstd-ex.com. The hostname
www.mstd-ex.com is aliased to www.geo.mstd-ex.com. Anyone
querying the mstd-ex.com name server for the address of www.mstd-
ex.com is told to ask one of the 7190s for the address of
www.geo.mstd-ex.com.

Step 4. Create Host and Specify Balancing Method.
When you create the hostname you can specify the balancing method
to use in selecting which site services are referred. For this scenario,
the balancing method eventually is Flash Response Mode. But for
initial testing of the network and configuration it is often best to
configure first with Weighted Round Robin mode. This allows for
easy verification of the configuration because the query responses are
deterministic. Once the initial configuration is verified the balancing
method can be changed to the production method (Part 2 of this
scenario).
