52.You are the Exchange administrator for your company. The Exchange organization contains 12 Exchange servers within a single administrative group. All Exchange servers run Exchange Server 2003. Each Exchange server contains four mailbox stores. The written company e-mail policy specifies a maximum amount of e-mail storage that each user is allowed to use. You need to ensure that the e-mail storage restrictions are consistently applied on all Exchange mailbox stores in the organization. You need to achieve this goal by using the minimum amount of administrative effort. What should you do?

A: Apply global message delivery options that define maximum message sizes.Correct: The setting of answer A is used to define a message size, and not to define the limitation for users storage.
B: Define mailbox store size limits for each mailbox store on all Exchange servers.
C: Configure a Mailbox Manager recipient policy that applies to all users in the organization.
D: Create a mailbox store policy that defines storage limits. Apply the policy to all mailbox stores.

Technical Knowledge
System policy:
Instead of manually configuring a common configuration on multiple Exchanger servers or stores, we can use a system policy to apply it to the desired objects. When we need modify, we can simply edit the system policy and have changes made to all objects.
We can create three different types of system polices: mailbox store policies, public folder policies, and server policies.

For example, we can configure mailbox store limits that define how much hard drive space a user’s mailbox is allowed to use. By using a mailbox store policy, we can easily apply uniform settings to all mailboxes in the mailbox stores to which the mailbox store policy is applied.

Recipient policy:
There are two types of recipient policies: Email Addresses policies and Mailbox Manager setting policies.
Email Addresses policy allows to change recipients Email suffix.
Mailbox Manager policy allows to configure what the Exchange mailbox manager is to do automatically to items in the selected folders once items have exceeded age or size limit. For example, we can use the Email Addresses policy to configure uses mail purging automatically when the mail has exceeded age and size limits.

Correct Answers: D

A: Incorrect: The setting of answer A is used to define a message size, and not to define the limit for user storage.
B: Incorrect: The settings of answer B may cost significant administrative effort.
C: Incorrect: Recipient policy is not used to configure user storage limit.
D: Correct

39.You are the Exchange administrator for your company. The Exchange organization contains two Exchange Server 2003 computers named Mail1 and Mail2. Mail1 functions as a mailbox server. Mail2 is configured as a front-end server and is used to handle all Microsoft Outlook Web Access connections from the Internet. HTTPS is not used for Outlook Web Access. Users report that Outlook Web Access and MAPI clients are slow during times of peak network usage. Network utilization of the Internet link does not reach capacity at these times. Management authorizes you to add an additional Exchange server to the network, to be named Mail3. You need to ensure that performance of Outlook Web Access is improved during peak network usage. What should you do?

A: Configure Mail3 as an Exchange front-end server. Instruct half of the users to connect to Mail2 when using Outlook Web Access. Instruct the other half of the users to connect to Mail3 when using Outlook Web Access.
B: Configure Mail3 as an Exchange front-end server. Configure a Network Load Balancing cluster that contains both Exchange front-end servers. Instruct all users to connect to the cluster name when they want to use Outlook Web Access.
C: Configure Mail3 as an Exchange front-end server. Create an alias (CNAME) resource record in DNS that maps to the IP addresses of both Exchange front-end servers. Instruct all users to connect to the alias when they want to use Outlook Web Access.
D: Configure Mail3 as an additional mailbox server. Move half of the user mailboxes to Mail3. Instruct all users to connect to Mail2 when they want to use Outlook Web Access.

====================================================================
Technical knowledge
Front-End is used for multiple-server organizations that provide mail access to their employees over the Internet. (About Front-End of exchange2003, We have talked about in previous article: How to offer your HTTP clients to have redundancy and acceptable client response times?)

Generally, slow access of mail client cause by some reasons. As shown in the following figure.

In this case, Network utilization of the Internet link does not reach capacity, and HTTPS is not used for OWA. So the reason that causing slow accessing is 4th reason listed in upper figure. To improve performance of OWA, we should configure Mail3 as an additional mailbox server, and then move half of the user mailboxes to Mail3.
Correct Answers: D

40.You are the Exchange administrator for A. Datum Corporation. The network contains two Exchange Server 2003 computers named Mail1 and Mail2. Mail1 contains all user mailboxes and is not accessible from the Internet. Mail2 is configured as a front-end server and is used for all Microsoft Outlook Web Access client connections from the Internet. Mail2 is also used as a relay for all incoming and outgoing SMTP messages. The company uses the domain name suffix adatum.com for all SMTP addresses. Users report that they do not receive non-delivery reports (NDRs) when e-mail messages cannot be delivered. You discover this only occurs when Mail2 cannot deliver e-mail messages addressed to Internet recipients. You need to ensure that users receive NDRs when delivery of Internet e-mail messages fails. Users must still be able to use Outlook Web Access from the Internet. What should you do on Mail2?

A: Configure the default SMTP virtual server to forward all mail with unresolved recipients to Mail1.
B: Configure the default SMTP virtual server to send a copy of the NDRs to the e-mail address of administrator@adatum.com.
C: Start the Microsoft Exchange Information Store service and mount the default mailbox store.
D: Create an SMTP connector and associate the connector with the namespace of adatum.com. Specify Mail1 as a smart host.
Correct Answers: C

==============================================================
Technical knowledge
For more security and more performance, some unnecessary services are disabled, public and mailbox store are disconnected and deleted, when we configure Exchange Front-End servers. Consequently, mail2 configured as Front-End server cannot deliver NDRs when mail2 fails to deliver e-mail to internet recipients.
So correct answer is C
