Your network contains an Active Directory forest named contoso.com.
Your company merges with another company that has an Active Directory forest named litwareinc.com.
Each forest has one domain.
You establish a two-way forest trust between the forests.
The network contains three servers. The servers are configured as shown in the following table.
You confirm that the client computers in each forest can resolve the names of the client computers in both forests.
On dc1.litwareinc.com, you create a zone named GlobalNames.
You need to recommend changes in both forests to ensure that the users in both forests can resolve single-label names by using the GlobalNames zone in
litwareinc.com.
Which changes should you recommend?
To answer, drag the appropriate configuration to the correct server in the answer area. Each configuration may be used once, more than once, or not at all.
Additionally, you may need to drag the split bar between panes or scroll to view content.

Deploying a GlobalNames zone
The specific steps for deploying a GlobalNames zone can vary somewhat, depending on the AD DS topology of your network.
Step 1: Create the GlobalNames zone
Step 2(Box 1, box 3) : Enable GlobalNames zone support
The GlobalNames zone is not available to provide name resolution until GlobalNames zone support is explicitly enabled by using the following command on every
authoritative DNS server in the forest:
dnscmd <ServerName> /config /enableglobalnamessupport 1
Step 3:Replicate the GlobalNames zone
Step 4: Populate the GlobalNames zone
Step 5 (box 2) : Publish the location of the GlobalNames zone in other forests
If you want DNS clients in other forests to use the GlobalNames zone for resolving names, add service location (SRV) resource records to the forest-wide DNS
application partition, using the service name _globalnames._msdcs and specifying the FQDN of the DNS server that hosts the GlobalNames zone.

Correct
Not correct.
The correct answer is:
– Create a GlobalNames service location (SRV) record
– Enable GlobalNames support
– Enable GlobalNames support
Explanation:
(Step 1: Create the GlobalNames zone on dc1.litwareinc.com)
Step 2: Enable GlobalNames zone support on every authoritative DNS server in the litwareinc.com forest
(Step 3: Replicate the GlobalNames zone)
(Step 4: Populate the GlobalNames zone)
Step 5: Publish the location of the GlobalNames zone in other forests
Step 5a: If you want DNS clients in other forests to use the GlobalNames zone for resolving names, add service location (SRV) resource records to the forest-wide DNS application partition, using the service name _globalnames._msdcs and specifying the FQDN of the DNS server that hosts the GlobalNames zone.
Step 5b: In addition, you must run the dnscmdServerName/config /enableglobalnamessupport 1 command on every authoritative DNS server in the forests that do not host the GlobalNames zone.
