Microsoft 70-081: Implementing and Supporting Microsoft Exchange Server 5.5
#41. Clients on your network use both IPX/SPX and TCP/IP. However, you want your Outlook clients to only use IPX. What file would you have to modify before installing the clients?
#42. Install MS outlook on network. You want to configure the install files so that users with mailboxes on any of the five Exchange server computers in you site can install the client application. What to do?
#43. You want to install Exchange Server for all users in your company's two main buildings. Building A has 15 users. Building B has 25 users. The buildings are connected to one another by dedicated routers and a 33.6 Kbps dial-up connection. Most of the messaging traffic will occur within each building. Less than 10 percent of the messaging traffic will occur between the two buildings. Which configuration should you implement to minimize traffic between the buildings?
#44. Your company uses a Microsoft Mail gateway for SMTP to transfer messages between its five post offices and the Internet. Your company domain name is Plumbers.com. Your network is connected to the Internet through a filtered router. Management has had you install a Microsoft Exchange Server and configure the Microsoft Mail Connector. Management has the following mandatory and optional wishes:
Required Result: replace the Microsoft Mail gateway for SMTP with the Exchange Server. Optional Result 1: POP3 clients being able to both send and receive messages. Optional Result 2: prevent anonymous users on the Internet from using the Internet Mail Service as a relay host for other destinations.
Proposed Solution: To accomplish those results, one member of the network administration staff suggests the following actions: Install the Internet Mail Service. Reconfigure the Gateway Access Components on each Microsoft Mail postoffice to point to the MS Mail Connector postoffice as the downstream postoffice. Disable rerouting of SMTP messages. Make no changes to the router.
#45. Your Exchange environment uses IMS to send and receive SMTP mail with a company named Sockets & Wrenches. Sockets & Wrenches uses a host-based SMTP mail system. When users on your system send mail to the name of the host at Sockets & Wrenches, it is not delivered. But if those users use an IP address for addressing, the mail is delivered. You are informed that other systems can send mail to S & W using a host name in the addressing. What should you do to enable your users to be able to send mail to S & W using a host name in the addressing? (Select the best answer)
#46. 50. Two organizations, Organization A and Organization B, need a long-term co-existence strategy. How could you allow LDAP clients to connect to Organization A and see the directories of both Organization A and Organization B?
#47. Your Exchange server is configured for anonymous LDAP clients, but those clients that are outside your firewall report that they cannot access the directory. What is the problem?
#48. Trojan Research removes its UNIX-based POP3 and SMTP server and replaces it with an Exchange Server computer that runs the Internet Mail Service. The new server has the same IP address and DNS host name as the previous server. When users connect to the new server from POP3 client applications, they can retrieve mail. However, the users receive an error message when they try to send messages via the Internet. What is the most likely cause of the problem?
#49. You configure LDAP to allow anonymous access. Users outside your firewall are unable to access the LDAP directory. What is the most likely cause of the problem?
#50. You are the administrator of an Exchange Server computer that hosts mailboxes for 500 users. You enable IMAP for all users. Your server is protected from the Internet by a firewall. Your firewall is configured to allow all IP traffic out to the Internet. It is also configured to allow SMTP (port 25), IMAP (port 143), and HTTP (port 80). Your IMAP service is configured as shown in the exhibit. You want to enable users to access the server from the Internet by using IMAP client application. Which other IP port must you allow through the firewall?
