Answers to Review Questions

10. A, B, D. In the site where you plan to install Exchange Server 2007 you must have a global

catalog as well as a domain controller from the same domain where Exchange Server 2007

is installed. Also, all global catalog servers located in the same AD site as Exchange Server

2007 servers need to be upgraded to Windows Server 2003 Service Pack 1 or later. In order

to increase performance, you can upgrade your domain controller to 64-bit machines, but

this is not a requirement.

11. B. In a smaller location the best practice is to put all three roles (Hub Transport, Client Access,

and Mailbox) required for a site on a single machine. This will preserve the budget but provide

full functionality. Installing Exchange Server 2007 on a domain controller is generally not rec-

ommended, and buying three machines would not be good for the budget. The last option,

using a single server and installing only the Exchange Mailbox role on it does not work because

a Mailbox server always requires a Hub Transport and a Client Access role to be installed in

the same AD site.

12. C. The first option is not correct as you cannot add other roles to a mailbox server that is clus-

tered. The second option is valid, but provides high availability only for the mailbox store. If

either the Client Access server or the Hub Transport server goes down, the complete location

will not be able to send messages. Thus it is not a preferred option. The third option considers

all aspects: the clustered Mailbox server as well as the Hub Transport and Client Access server

roles installed on both machines, thus providing failover. Unified Messaging is part of the

Client Access server, so that requirement is also satisfied. The last option does not provide

sufficient availability for a large site.

13. A, C, D. Exchange Server 2007 requires TCP/IP v4 and does not support TCP/IP v6 yet. The

DNS must be installed as the primary name-resolution method. All AD sites that host Exchange

Servers must have a permanent WAN or LAN link between them—dial-up is not supported any-

more in an Exchange Server 2007 organization.

14. A, C. Only call answering and voice access to mailbox are features of Unified Messaging.

Sending faxes is not supported, but receiving faxes is. Delayed fan-out is not a feature of

Unified Messaging, but rather a feature of Exchange Server 2007 routing.

15. A. In order to replace the existing smart relay servers, you should install the same number of

stand-alone Edge Transport servers (important as they are located in an insecure network), and

in order to receive organizational configuration from the Exchange organization, the servers

must establish an Edge subscription each. Using the Hub Transport server for these tasks is not

correct as this server role is not as secure for Internet-facing traffic as the Edge Transport server

is. Joining an Edge server to a domain is also not secure!

16. A, B, C, E. The Exchange routing table consists of AD sites, AD site links, Exchange servers

and their relation to AD sites, SMTP connectors, third-party connectors, mailbox and public

folder stores, as well as legacy Exchange 2000/2003 routing groups and connectors. Client

Access servers do not route any messages, and thus are not part of the routing table.
