You are the messaging engineer for your company. The company has a Microsoft Exchange Server 2003 messaging system.
The company is transitioning from the current messaging system to Exchange Server 2007. You deploy an Edge Transport server named Server1. Server1 receives all e-mail messages from the Internet.
Server1 is located in the perimeter network and can communicate to servers on the internal network over TCP Port 25 only. Multiple anti-spam agents are enabled on Server1. No other Exchange Server 2007 servers are deployed on the network.
You need to recommend a high-availability solution that meets the following requirements:
The company must continue to receive e-mail messages from the Internet if Server1 becomes unavailable.
The company must continue to filter e-mail messages with anti-spam agents if Server1 becomes unavailable.
Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)
A.
On the internal network, install a new Hub Transport server.
B.
On the perimeter network, install a new Edge Transport server.
C.
Clone the Edge configuration from Server1 on the new Hub Transport server.
D.
Clone the Edge configuration from Server1 on the new Edge Transport server.
E.
Restore Active Directory Application Mode (ADAM) from Server1 on the new server.
Explanation:
For redundancy, deploy more than one Edge server in the perimeter network.Use cloned configuration scripts: ExportEdgeConfig.ps1 (Exports settings and data to an XML file) and ImportEdgeConfig.ps1 (Imports information stored in this XML file) to achieve consistency in settings.
Load balance inbound SMTP traffic by defining multiple MX records in DNS for your mail domain, each with the same priority.
Run the EdgeSync process separately for each Edge server, since cloned configuration doesnt duplicate Edge Subscription settings. EdgeSync certs dont get cloned.
EdgeSync overwrites any settings included in both cloned configuration and EdgeSync replication information. These include Send connectors, Receive connectors, accepted and remote domains.
