Your company has two offices. Each office is configured as an Active Directory site.
You have an Exchange Server 2013 organization that contains four servers. The servers are
configured as shown in the following table.
MBX1 and MBX2 are members of a database availability group (DAG) named DAG1. A mailbox
database named DB1 has a copy on each Mailbox server. DB1 is active on MBX2.
You are creating a disaster recovery plan for the organization.
You need to identify how email messages will be received for the mailboxes on DB1 if the Exchange
Server transport services fail on MBX2 because of messages in the poison message queue.
What should you identify?
A.
Email messages will be queued on MBX1, and then delivered directly to the mailboxes on MBX2.
B.
The Exchange Server transport services will restart automatically, and then put all delivery queues
in a Retry state.
C.
The Exchange Server transport services will restart automatically, and then purge the poison
messages.
D.
Email messages will be queued on CAS1 or CAS2, and then delivered directly to the mailboxes on
MBX2.
If the transport system thinks that a message is corrupt and likely to cause problems such as provoking a software crash, it considers the message poison and isolates it in
a queue the administrator can examine to decide whether the message really is a problem.
B-C–WRONG–Messages in the poison message queue are never automatically resumed or expired. Messages remain in the poison message queue until they’re manually resumed or removed by an administrator.
Any messages in the poison message queue are in a permanently suspended state.
E–WRONG–Queue is a temporary holding location for messages that are waiting to enter the next stage of processing or delivery to a destination. Each queue represents a logical set of messages that the Exchange server processes in a specific order. Queues exist in the Transport service on Mailbox servers.
