Exchange Server 2007/2010 interview questions and answers – Part 2

Dear All, this is the second part, I hope the below question bank will help you.

Exchange Transport Role

1. Where does Exchange 2007 get its routing topology from?
Exchange 2007 uses the Active Directory site topology to determine how messages are transported in the organization. The Hub Transport server uses the Active Directory Topology service to retrieve the Exchange organization’s configuration information. Unlike earlier versions of Exchange, Exchange 2007 does not use a link state routing table and does not try to calculate an alternative route when a connection is unavailable.

2. What is a Mail Relay? Name a few known mail relay software or hardware options?
3. What’s a Smart Host? When would you configure and use it?
4. What is Send Connector?
Send Connector

5. What is Receive Connectors? Provide two default receive connector names?
Receive Connector: By default, when you install the Hub Transport server role, two Receive connectors exist. No additional Receive connectors are needed. The default Receive connectors do not require any additional configuration changes.


Default Receive connector:
(A) Client <Servername>: This Receive connector accepts SMTP connections from all non-MAPI clients, such as POP and IMAP. This connector work on port 587.
(B) Default <Servername>: This Receive connector accepts connections from Edge Transport servers to receive messages from the Internet and from other Hub Transport servers. This connector work on port 25

What’s the major issue blocking you from receiving e-mail from the world, considering you’ve enabled the right port(s) on the firewall, and properly configured MX records for your domain(s)?
6. What’s the difference between the “Client” and the “Default” Receive Connectors?
You’re looking to troubleshoot e-mail delivery issues. Name 4 options/tools/logs that are built into Exchange 2007/2010 that can help you in your task.

7. How to enable Anti-Spam features on the HT role and what is the recommendation?
8. Where does Edge role store its settings?
Edge Transport server role installed doesn’t have access to Active Directory. The Edge Transport server stores all configuration and recipient information in ADAM. Because Active Directory and ADAM both use Lightweight Directory Access Protocol (LDAP), and because both directory services use the Exchange 2007 schema, you can replicate data from Active Directory to ADAM.

Types of Data Replicated to ADAM
A. Edge Subscription information
Provision and maintain the credentials to help secure the LDAP connection.
Arbitrate the synchronization lock and lease process.
Optimize the EdgeSync synchronization process

B. Configuration information
Hub Transport servers
Accepted domains
Message classifications
Remote domains
Send connectors
Internal SMTP servers
Domain Secure lists

C. Recipient information
Proxy addresses
Safe Senders List and Safe Recipients List
Per recipient anti-spam settings

D. Topology information
Notification of newly subscribed Edge Transport servers. This data is refreshed every five minutes.

9. How to enable high-availability and load balancing on Edge servers?
10. What is Edge subscription and process to enable Edge subscription?
Exchange 2007 Edge Transport server role is always deployed in organization’s DMZ (perimeter) network. Edge Transport server handles all Internet mail flow. It also provides some additional protection and security provided by a series of agents running on the Edge Transport server. These agents protect messages against viruses and spam and apply transport rules to control message flow.

This is an optional process, subscribing an Edge Transport server provide anti-spam features, recipient lookup or safelist, or secure SMTP communications.

Edge Subscription Process
A. Make sure that the Hub Transport servers and the Edge Transport server can resolve the each other FQDNs by using DNS.
B. Run the New-EdgeSubscription cmdlet in the EMS on the Edge Transport server to export the Edge Subscription file.
C. Copy the Edge Subscription file to a Hub Transport server.
D. Run the New-EdgeSubscription cmdlet in the EMS or EMC to import the Edge Subscription file.

11. What’s the default replication interval for Edge sync and what is the step to force replication?
When the Exchange Edge server starts, the Microsoft Exchange EdgeSync service starts and establishes a synchronization schedule.
Configuration data is synchronized to ADAM once every hour.
Recipient data is synchronized to ADAM once every four hours.

You cannot modify the synchronization intervals.

Steps to Sync Edge sync replication
Use the EMS to immediately start synchronization of data from the Active Directory service to the subscribed Edge Transport servers. Run the below command on the HB transport server.

Start-EdgeSynchronization -Server <Hub Transport server name>

12. What ports required to open between the DMZ holding the Edge role and internal network?

13. How to configure E-mal routing to be able to send e-mail externally (to the Internet) and what do you need to do?

14. What are the default connectors created during the Exchange Edge subscription?

When we do the EdgeSync synchronization process, it creates two send connector which then replicated to ADAM.
A Send connector that is configured to relay e-mail messages from the Exchange organization to the Internet.
Connector Name: EdgeSync – <Site Name> to Internet

A Send connector that is configured to relay e-mail messages from the Edge Transport server to the Exchange organization.
Connector Name: EdgeSync – Inbound to <Site Name>

Name EdgeSync – <Site Name> to Internet EdgeSync – Inbound to <Site Name>
Address Space SMTP:*;100 SMTP:–;1
Source Servers Edge Subscription name Edge Subscription name
The name of the Edge Subscription is the same as the name of the subscribed Edge Transport server.



DNS Routing Enabled



Domain Secure Enabled (Mutual Auth TLS)
