352Chapter 7Building Administrative and Routing Groups11. A, C. In order to be in the same routing group, all servers must havereliable, permanent, and direct network connectivity that supports SMTP. They must also belong to the same Active Directory forest and be able to connect to a routing group master.12. D. The only connector that you can force to use SMTP is the SMTPConnector. Actually, you don force it; it the only protocol it supports. This makes it ideal when you need to configure a connector to use SMTP between a routing group and an Exchange 5.5 site because the Routing Group Connector will default to RPC in this situation when an SMTP connection cannot be established.13. A. The switch to native mode is a one-time, one-way switch and isirreversible. Native mode allows your Windows 2000 domain controllers to scale into the millions of objects per domain instead of the 40,000 accounts that Windows NT 4.0 can support.14. B. The SMTP Connector is more configurable than the RoutingGroup Connector, offering the ability for more fine-tuning of the connection. The SMTP Connector offers the ability to issue authentication before sending mail, specifying TLS encryption, and removing mail from queues on remote servers.15. A. To forward mail upstream to another SMTP server instead, selectthe Forward All Mail Through This Connector To The Following Smart Host option on the General property page for the connector. Also, you might want to specify the IP address instead of the name for the smart host so that no DNS query is required to resolve the name.16. A. Although you can schedule delivery times on each of the connec-tors, only the Routing Group Connector also allows you to create a special schedule based on message size.Copyright 2001 SYBEX, Inc., Alameda, CAwww.sybex.com
