| Appendix A. Answers to Review Questions

1.	C Cisco CallManager installs using Windows 2000 as a foundation operating system.
2.	D and E By default, all Subscriber servers install with the IIS web services enabled. This opens a point of access for a potential intruder. In addition, it consumes resources on the server that could be used for other mission-critical services that the Cisco CallManager provides.
3.	B The Hardware Detection disk allows the installation program to determine which operating system software image is appropriate for your MCS platform. The Hardware Detection disk only recognizes Cisco-approved hardware.

4.	C To install multiple servers into a cluster, you must first configure hostname resolution. The most common method is through DNS; however, if DNS is unavailable, you can statically type a LMHOSTS file on each of the servers, which is nothing more than a text file mapping hostnames to IP addresses.
5.	A, B, and E The following services are not typically used on a production Cisco CallManager server platform: - DHCP client - Fax service - FTP Publishing Service - Smart Card - Smart Card Helper - Computer browser - Distributed File System - License Logging Service
6.	C The Set Default button activates the minimum services necessary to run the Cisco CallManager in a single-server configuration.
7.	B After the Cisco CallManager installation has completed, you should activate all services the Cisco CallManager will use. If you apply any configuration before you activate the services, unpredictable results can occur.
