MCITP Microsoft Exchange Server 2007 Messaging Design and Deployment Study Guide phần 4 pps

226 Chapter 5  Defining Policies and Security Procedures Finally, we covered some additional tweaking you should do to make your Exchange organi- zation as secure as possible. We investigated how you can secure your environment by delegating Exchange Administrator roles and by securing SMTP email. To finish we covered Information Rights Management. Exam Essentials Legal and company requirements for messaging policies There are both legal and company requirements that force you to configure messaging policies to control mail flow and mail storage. You need to know the difference between transport rules and journaling rules. You might also receive a question about client licensing requirements, and about the archiving possibilities trans- port rules offer. A lot of questions on the exam ask you about the possible configuration options for messaging records management and about message classifications. Antispam in Exchange Server 2007 The exam focuses very hard on the antispam options in Exchange Server 2007, and what is added if you introduce Exchange Hosted Services and Microsoft Forefront for Exchange to your Exchange environment. Make sure that you know what the different antispam filtering options entail. Exchange Administrative Permissions The exam will check if you know about the new Exchange Administrator roles; make sure that you can list them and that you know what rights users will get when they are delegated an Exchange Administrator role. You have to know the advantages and possible disadvantages of securing SMTP email traffic, and what Information Rights Management can offer your Exchange organization. 81461.book Page 226 Wednesday, December 12, 2007 4:49 PM Review Questions 227 Review Questions 1.

Encrypting messages will make sure that only the intended recipient can view the contents. Sender filtering, recipient filtering, and content filtering are used to prevent spam from entering the exchange organization. Digital signatures will allow the recipient of the message to be sure the sender actually sent the message but the message itself will not be encrypted when sent. 2. D. You don’t want to invest in new hardware and software, so you cannot go for the Edge Transport server role. You want to stop spam before it reaches your messaging environment, thereby eliminating the possibility of deploying the antispam agents on the Hub Transport server. It is not possible to deploy antispam agents on the Mailbox server. You can only choose to use Exchange Hosted Services. 3. B. You don’t want to invest in new hardware and software, so you cannot go for the Edge Transport server role. Since you want to reduce the amount of spam that reaches your users’ mailboxes, you should enable the antispam transport agents on your Hub Transport server. You don’t want to stop spam from entering your organization, you just want to stop spam from reaching the user’s mailboxes, thereby there is no requirement to go for Exchange Hosted Services. 4. A and B. Because you are using the Standard Edition version of Exchange Server 2007, you are not able to create an additional store since you already have the maximum number of stores in use. The Standard Edition version of Exchange only supports the creation of five stores. You can, however, create a new universal distribution group and use a new feature available in Exchange Server 2007: per-distribution-group journaling. 5. A. It is best practice to enable authentication to provide additional security for email sent from associated organizations. Creating a dedicated SMTP Send Connector does not provide secure mail flow if you don’t require authentication. Installing and configuring MIIS would enable directory synchronization which is not asked for in this scenario. The Exchange organization’s connector does not exist. 6. A. Sender ID filtering can provide you with a valid result only if the sender’s domain has a Sender Policy Framework (SPF) record registered in DNS. 7. B. You can use the Exchange Management Console or Exchange Management Shell to con- figure disclaimers on computers that have the Hub Transport server role installed. Creating and registering a transport event sink is not recommended. Educating your users will require more effort than creating a transport rule. You shouldn’t apply a transport rule to messages that are sent inside your organization, because you only want messages that go outside the organization to receive a disclaimer. 8. A. You can configure a transport rule to prepend a subject with a string, and you can specify the value of the SCL as a condition. A journaling rule is used to journal messages, and therefore not valid for changing a message subject. Creating a transport event sink would require admin- istrative effort to create and deploy it. Group policies cannot be used to change the subject of a mail. 81461.book Page 233 Wednesday, December 12, 2007 4:49 PM 234 Chapter 5  Defining Policies and Security Procedures 9. B, C, and E. Deleted item retention time is the amount of time that messages that are deleted from the mailbox are available for recovery. We are covering the messages that are still in the mailbox, in the Deleted Items folder, so deleted item retention time doesn’t matter here. Instead, it is feasible to create two new Deleted Items managed folders and specify for each one different managed content settings, and use managed folder policy to hand them out to the users that need those settings. 10. D. You can configure connection filtering to check with real-time Block lists if the connecting SMTP server is a known relaying server. 11. C. Sender ID filtering will check if the sender (or most probable sender) is sending the mail using the SMTP services of a server that is authorized to send mail from that sender’s domain. If there is an SPF record configured for the SMTP mail domain, you can check if domain spoofing is done. Sender filtering only provides the ability to block mail from specific domains, without checking if it’s spoofed or not. Recipient filtering is used to filter mail sent to specified recipients, and Connection filtering is used to check if the connection was initiated from a valid IP address. 12. B. A user needs to have the Exchange Recipient Administrator role in order to be able to give users a mailbox. 13. A. To be able to fully manage an Exchange organization, a user needs to be delegated the Exchange Organization Administrator role. 14. A and B. If you want to enable the use of message classifications in Outlook, you need to deploy on the client computer a local file (Classifications.xml) that contains the defini- tions of the message classifications. And you also need to create and deploy a registry key that will enable the use of message classification by referencing the Classifications.xml file on the client computer. You don’t need to add a registry key on the Exchange Mailbox servers, and you don’t need to deploy a local file on the Exchange Mailbox servers. 15. C. Information Rights Management can be used in Microsoft Office Outlook 2003 and Microsoft Office Outlook 2007 to prevent email forwarding, copying, editing, or printing. Implementing signing and sealing will not prevent a user from forwarding or copying the con- tents of an email message. A secure SMTP connection only secures the SMTP mail flow, but does not imply that the email message is not able to be forwarded or copied. 16. B and C. You need at least Microsoft Office Outlook 2003 to be able to use the services pro- vided by IRM. You can use the abilities offered by IRM by running Office Outlook 2003 (or later) on XP Professional. You don’t need to have Windows Rights Management server, since you can use the limited-trial version offered by Microsoft. 17. E. Digital signatures provide authentication, nonrepudiation, and data integrity. By digitally signing your email messages, you enable recipients to verify if the email message has been sent by the person or organization that claims to have sent the message, and you enable recipients to verify if the message has been altered. 18. D. You need to delegate the role of Exchange Server Administrator since you want your new colleague to have full control over the specified servers’ configuration data. 81461.book Page 234 Wednesday, December 12, 2007 4:49 PM Answers to Review Questions 235 19. B. Attachment filtering allows you to block attachments from entering your Exchange orga- nization, by attachment content type, or by attachment file name. You can enable and config- ure attachment filtering only on the edge Transport server. Content filtering is set as an SCL value for messages so you can configure your Edge or Hub Transport server to block them, quarantine them, or deliver them to a user’s junk mail folder. 20. D. Forefront Security for Exchange Server enables you to quarantine blocked attachments. Attachment filtering, content filtering, and recipient filtering do not allow you as an adminis- trator to have blocked attachments sent to a quarantine mailbox. 81461.book Page 235 Wednesday, December 12, 2007 4:49 PM [...]...8 146 1.book Page 236 Wednesday, December 12, 2007 4: 49 PM 8 146 1.book Page 237 Wednesday, December 12, 2007 4: 49 PM 70-238: Pro: Deploying Messaging Solutions with Microsoft Exchange Server 2007 PART II 8 146 1.book Page 238 Wednesday, December 12, 2007 4: 49 PM 8 146 1.book Page 239 Wednesday, December 12, 2007 4: 49 PM Chapter 6 Planning an Upgrade to Exchange Server 2007 MICROSOFT EXAM OBJECTIVES... organization to Exchange Server 2007 The main subjects in this chapter are as follows: Exchange 2000 Server features not supported in Exchange Server 2007 Exchange Server 2003 features not supported in Exchange Server 2007 Features that are gone in Exchange Server 2007 De-emphasized features in Exchange Server 2007 Planning the upgrade process from Exchange 2000 Server and Exchange Server 2003 Planning... with Exchange Server 5.5 Exchange Server 2007 does not support coexistence with Exchange Server 5.5 If your Exchange organization still uses Exchange Server 5.5, you will need to transition first to Exchange 2000 Server or Exchange Server 2003, followed by transitioning to Exchange Server 2007 8 146 1.book Page 250 Wednesday, December 12, 2007 4: 49 PM 250 Chapter 6 Planning an Upgrade to Exchange Server. .. foreign X .40 0 mail environment, plan to keep at least one Exchange 2000 Server or Exchange Server 2003 server in your organization 8 146 1.book Page 248 Wednesday, December 12, 2007 4: 49 PM 248 Chapter 6 Planning an Upgrade to Exchange Server 2007 Administrative Groups Administrative groups were introduced with the release of Exchange 2000 Server Every Exchange 2000 Server or Exchange Server 2003 server. .. to Exchange Server 2007, you will be transitioning your Exchange organization to 2007 However, when you decide to upgrade your existing Exchange 2000 Server or Exchange Server 2003 to a new Exchange Server 2007 organization you will be migrating to Exchange Server 2007 Upgrading from Exchange 5.5 or any other third-party messaging system to Exchange Server 2007 is also referred to as migrating to Exchange. ..
