You are the messaging engineer for your company. Your company has a main office in London and branch offices in Montreal, New York, Tokyo, and Toronto.

Your network consists of an Edge Transport server and five Hub Transport servers. The Edge Transport server routes all e-mail received from the Internet. The Edge Transport server has anti-spam agents enabled and configured. The network is configured as shown in the exhibit.

You need to design an Internet e-mail solution that meets the following requirements:

Filters spam in the event that an Edge Transport server fails.

Sends and receives e-mail from the Internet in the event that an Edge Transport server fails.

Which two elements should your design include? (Each correct answer presents part of the solution.

Choose two.)

A.
Enable EdgeSync between the Edge Transport server and the New York Hub Transport server.

B.
Enable EdgeSync between the Edge Transport server and the London Hub Transport server.

C.
Enable Anonymous authentication on the Receive connector for the Tokyo Hub Transport server.

D.
Enable Partner authentication on the Receive connector for the Tokyo Hub Transport server.

E.
Add an A record and an MX record in the companys Internet DNS zone for the Tokyo Hub Transport
server. Run the install-AntispamAgents.ps1 script on the Tokyo Hub Transport server.

F.
Add an A record and an MX record in the companys Internet DNS zone for the Tokyo Hub Transport server.
Run the ImportEdgeConfig.ps1 script on the Tokyo Hub Transport server.

Explanation:
To establish external mail flow directly thru a Hub server, create a Send connector to route mail out to, and modify the configuration of the default Receive connector to accept anonymous connections in from, the Internet.

Install anti-spam agents directly on the Hub server by running the Install-AntiSpamAgents.ps1 script, located in the %system drive%/Program Files/Microsoft/Exchange Server/Scripts folder. Register MX resource records for all accepted domains in a public DNS server.

To create a Send connector to transmit mail out to the Internet:

EMC > Organization Configuration > New Send Connector…

Or:

New-SendConnector -Name “Internet” -Usage Internet -AddressSpaces “*” -SourceTransportServers <Hub computer name> -DNSRoutingEnabled: $true -UseExternalDNSServersEnabled: $true

To modify the configuration of the default Receive connector:

EMC > Server Configuration > Hub Transport > Receive Connectors > Default Server Name connector > Properties > Permission Groups > Check Anonymous Users

Set-ReceiveConnector -Name “Default Server Name” -Server <Hub computer name> -PermissionGroups AnonymousUsers,ExchangeUsers,ExchangeServers,ExchangeLegacyServers
