You administer a Windows Essential Business Server 2008 environment. The network contains servers running Windows Server 2008. You want to install a new Exchange Server 2007 computer on the network. The new Exchange Server will be used by mobile device users to access their mailboxes. To achieve this, you want to configure Exchange ActiveSync on the new Exchange Server. You need to ensure that Exchange ActiveSync is enabled by default.
Which Exchange Server role should you install on the new server?
A.
Mailbox server role
B.
Client Access server role
C.
Hub Transport server role
D.
Edge Transport server role
Explanation:
You should install the Client Access server role to configure ActiveSync for mobile device users. Exchange ActiveSync is an Exchange synchronization protocol that enables mobile device users to access their email, calendar, contacts, and tasks by using their mobile devices. Exchange ActiveSync synchronizes e-mail messages, calendar items, contacts, and tasks. Exchange ActiveSync is enabled by default when you install the Client Access server role. The Client Access server provides Outlook Web Access, mobility connectivity, and Web services to clients in an Exchange organization.You should not install the Mailbox server role, the Hub Transport server role, or Edge Transport server role because Exchange ActiveSync is installed when you install the Client Access server role. The Mailbox server hosts mailboxes, public folders, and core services, including calendaring. The Hub Transport server provides internal message routing and encryption. The Edge Transport server is deployed in the perimeter network and it is the only server role that cannot reside on the same server as the other roles. The Edge Transport server acts as a Simple Mail Transfer Protocol (SMTP) gateway and provides antivirus, antispam, and messaging security services.
