Your network contains servers that run Windows Server 2008. Microsoft Windows SharePoint
Services (WSS) are available on the network. WSS is only accessible from the internal network.
Several users use devices that run Windows Mobile 6.0. The users can establish only HTTP and
HTTPS sessions from the Internet. You need to enable users to access WSS from the Internet by
using their Windows Mobile devices. The solution must ensure that all connections from the Internet
to WSS are encrypted. What should you do?
A.
Install Microsoft Internet Security and Acceleration (ISA) Server 2006 and create a HTTPS
publishing rule.
B.
Install Microsoft Internet Security and Acceleration (ISA) Server 2006 and create a Secure RPC
publishing rule.
C.
Install the Network Policy and Access Services (NPAS) role and enable Secure Socket Tunneling
(SSTP) connections. Configure WSS to require Kerberos authentication.
D.
Install the Network Policy and Access Services (NPAS) role and enable Secure Socket Tunneling
(SSTP) connections. Configure WSS to require IPsec encryption.
Explanation:
To ensure that mobile users are allowed to access WSS from the Internet by using their Windows
Mobile devices securely and to ensure that all the connections from the Internet to WSS are
encrypted, you need to use external Firewall solution by using Microsoft Internet Security and
Acceleration ISA Server 2006 and create a HTTPS publishing rule on ISA Server. The Firewall will
ensure a secure connection to the internal network of the company. When you publish an
application through ISA Server 2006, you are protecting the server from direct external accessbecause the name and IP address of the server are not accessible to the user. The user accesses the
ISA Server computer, which then forwards the request to the server according to the conditions of
the server publishing rule. When you create a secure Web publishing rule, you can configure how
SSL requests will be redirected as Hypertext Transfer Protocol (HTTP) requests or as SSL requests.
