You are the Exchange administrator for your company. The intranet is connected to the Internet through a firewall.
The Exchange organization contains two servers named Mail1 and OWA1. Both servers run Exchange Server 2003.
Mail1 is configured as a mailbox server. OWA1 is configured as a frontend server. OWA1 is configured to allow users to access their email by using Microsoft Outlook Web Access over SSL.
Internet in each domain to make LDAP OWA1. However, intranet users can use either HTTP or HTTPS to access Outlook Web Access.
You need to ensure that all users can access Outlook Web Access by using only HTTPS.
What should you do?
A.
Configure the firewall to permit Internet users to access port 443 on OWA1. Configure the default Web site on OWA1 to require SSL.
B.
Configure the firewall to permit Internet users to access port 80 on OWA1. Configure the default Web site on Mail1 to use port 443 for SSL communications.
C.
Configure the firewall to allow Internet users to access port 993 on OWA1. Configure the default Web site on Mail1 to require SSL and 128bit encryption.
D.
Configure the firewall to allow Internet users to access port 143 on OWA1. Configure the Exchange HTTP virtual server on OWA1 to enable formsbased authentication for Outlook Web Access.
Explanation:
SSL utilizes port 443. The external firewall does not currently allow port 443 traffic to pass. Opening up this port will take care of that
issue. The default OWA site is currently not correctly setup to use HTTPS. This is why internal clients can connect to OWA using
HTTP. Modifying the security on the OWA web site will solve this problem.
Incorrect Answers:
B. Port 80 is used for standard HTTP traffic. Allowing it will not satisfy the requirement of HTTPS traffic being passed only.
C. Port 993 is used for secure IMAP traffic. Enabling it will not allow HTTPS traffic.
D. Port 143 is used for insecure IMAP traffic. It will have no effect on HTTPS traffic.
