Your network contains one Active Directory site. You have an Exchange Server 2010 organization
that contains the following servers:
• A Client Access server named CAS1.
• A Hub Transport server named Hubl.
• Two servers named Serverl and Server2. Both Serverl and Server2 have the Mailbox server role
installed, the Client Access server role installed, and are members of a database availability group
(DAG).
You need to ensure that users can send e-mail messages to the Internet if a single server fails. What
should you recommend?
A.
Add the Hub Transport server role to CAS1. Modify the Send connector.
B.
Add an Edge Transport server. Create a new Edge subscription.
C.
Add the Client Access server role to Hub1. Create a Client Access server array.
D.
Add an Edge Transport server. Configure a Network Load Balancing cluster.
Explanation:
Pass4Sure did not have an answer for this question
The question is asking that users can send mail if a single server fails. As I read the question I see
only one Hub Transport Server which is Hub1
So I feel that A – adding another hub server to Cas1 will provide the solution
