Review Questions

1. ‚	You have configured three storage groups on your Exchange server. One group holds five mailbox stores and no public stores. The other two groups are configured with two public stores each and no mailbox stores. How many transaction logs are maintained on the system? One Three Five Nine
2. ‚	You have just installed a new drive on your Exchange server and would like to move the transaction logs for one of your storage groups to that drive. Where would you go to do this? The Logging property page of the server object that holds the storage group. The Database property page for the storage group object. The General property page for the storage group object. You cannot do this. Once a transaction log is created, it cannot be moved.
3. ‚	Which of the following does the Standard Edition of Exchange Server 2003 support? (Choose all that apply.) Multiple public stores Multiple mailbox stores Multiple storage groups Databases up to 16 GB Databases of any size
4. ‚	You are an assistant Exchange administrator for a large network. Your supervisor asks you to check a set of mailboxes to determine the last time the user logged on. How would you do this? Use the Advanced General page of the user ‚ s profile in Active Directory Users and Computers. View the Tools container in System Manager. View the Mailboxes container in System Manager. View the Logons container in System Manager.
5. ‚	For security reasons, you have decided to configure your mailbox storage group to zero out deleted databases. You realize that this process does not occur until after an online backup is performed, but you have decided that is secure enough for your purposes. What other concern does using this feature raise? The performance of the server will suffer. Online backups will take considerably longer. Users will no longer be able to recover deleted items from their client application. Multiple log files will be created that must be included in a backup routine.
6. ‚	You are planning storage on an Exchange server. You need to create two mailbox stores, one for general use and one for executive use. You also need to create one public store. All three stores will be created in a single storage group. As a required part of this process, you must ensure that the database for the executive mailbox store can be re-created from uncommitted log files. This requirement does not exist for the general mailbox store or the public folder store. In addition, it is desired (but not required) that you be able to perform both full and incremental backup jobs on all three stores located on this server. As well, it is desired (but not required) to minimize the amount of disk space that the general mailbox and public stores use by limiting the creation of new log files. To achieve these results, you propose to perform the following actions: ‚ Create a single storage group. ‚ Configure the executive mailbox store to use circular logging and to zero out deleted database pages. If you complete the proposed actions, will you have achieved the required and/or desired results? You will achieve both the required result and the two desired results. You will achieve the required result and only one of the desired results. You will achieve only the required result. You will not achieve the required result.

9. ‚	You have an organization that consists of three servers: Server1, Server2, and ServerServer1 and Server2 contain only the default storage groups named First Storage Group, and each of those storage groups contain the default public store and mailbox store. The same is true of Server3, but here you have also configured a storage group named Executive that holds a single mailbox store for executive mail and another storage group named Jupiter that contains a public store for a new public folder tree. Server1 and Server2 are in one routing group, and Server3 is in another. Server1 is a member of one Windows Server 2003 domain, and Server2 and Server3 belong to a second Windows Server 2003 domain. Your organization is running in native mode. Which of the following statements are true? (Choose all that apply.)

You could move a mailbox from the mailbox store on Server1 to the Executive store on Server3. You could move a mailbox from the mailbox store on Server2 to the mailbox store on Server3. You could move a mailbox from the mailbox store on Server2 to the Executive store on Server3.
10. ‚	You are planning to index a large public store. You are concerned that during the time it takes to index the store, users will submit reports of incomplete or inaccurate searches. How can you solve this problem? Dismount the store while the indexing takes place. Use the Full-Text Indexing property page of the store object to disallow searching while the indexing takes place. Use the General property page of the index to disallow searching while the indexing takes place. E-mail your users and let them know that search functions will be unavailable for a certain amount of time.
11. ‚	Which of the following files is used to keep track of the information in a transaction log that has already been committed to the database? EDB.LOG CHECK.LOG EDB.CHK RES1.LOG
12. ‚	In which of the following directories would you find the database files for the default public and mailbox stores created during Exchange Server 2003 installation? \Program Files\Exchsrvr\Mdbdata \Program Files\Exchange\Mdbdata \WINNT\Exchsrvr\Mdbdata \WINNT\Exchange\Mdbdata
13. ‚	You have an Exchange server that contains three storage groups. The first storage group contains a single mailbox store that consumes 10 GB of disk space. The second storage group contains two mailbox stores, each consuming 4 GB of disk space. The third storage group holds a single public store that consumes 5 GB of disk space. You want to enable full-text indexing on all of these stores. How much total disk space should the stores consume after indexing is complete? 23 GB 25.3 GB 27.6 GB 34.5 GB 46 GB
14. ‚	One of your Exchange servers has unexpectedly shut down its Information Store service. You check the Event Log and discover that the disk containing the log files for the Information Store has run out of space. What has happened to any transactions that were outstanding when the problem occurred? The transactions are stored in memory and must be committed before shutting down the computer. The transactions are written to reserve logs and will be committed when the IS comes back online. Circular logging is turned on, and the oldest committed transaction log is overwritten. The transactions are lost.
15. ‚	Which of the following statements is true of working in a mixed-mode organization? You cannot rename a storage group after its creation. You can rename a storage group at any time. You can rename a storage group, but you must dismount all stores in the group first. You can rename a storage group but only if all transaction logs are fully committed.
16. ‚	You recently created a mailbox store for use by executives in your company. You would like to create a public folder and have copies of all messages sent to users in that mailbox store sent to the folder as well. How could you do this? Configure the store to archive messages using the store ‚ s General property page. Configure the store to archive messages using the store ‚ s Advanced property page. Make regular backups of the mailbox store, and then restore those messages to the public store where the folder is kept. You cannot do this except by creating a custom program.
17. ‚	One of your assistant administrators has mistakenly purged a user ‚ s mailbox, thinking that the command was used to empty all messages from the mailbox. Instead, the mailbox has been deleted. How can you recover the mailbox? Purged mailboxes are disabled only for a specified period of time before being deleted. During this time, you can recover them from System Manager. Purged mailboxes are disabled only for a specified period of time before being deleted. During this time, you can recover them from Active Directory Users and Computers. You cannot recover the mailbox. You must create a new one for the user.
18. ‚	You are helping a small-business owner install Exchange Server on his network. He plans to use only one Exchange server and does not plan to use public folders. To save some system resources, you decide to remove the public folder store from the server. When you try to delete the store, however, System Manager will not let you. What could be the problem? You must remove all public folders from the store before deleting the store. You can delete a store only after dismounting it. You cannot delete the only store in an organization that contains a public folder tree. You cannot delete a public store from an Exchange server at all.
19. ‚	Which of the following statements is correct? You can create a full-text index for an individual store. You can create full-text indexes only for entire storage groups. You can create full-text indexes only for entire servers. Full-text indexing is either on or off for a whole organization.
20. ‚	Your users are complaining that the search results they get when looking for messages in certain public folders are always outdated by several days. You recognize that all of the folders are part of the same public store and that full-text indexing is turned on for the store. What is the best way to make the searches better for the users? Decrease the Update Interval option on the Full-Text Indexing property page of the public store. Decrease the Update Interval option on the Interval property page of the full-text index. Adjust the schedule at which updating occurs using the Schedule property page of the public store. Adjust the schedule at which updating occurs using the Schedule property page of the full-text index.

Answers

1. ‚	B. Only one transaction log is maintained for each storage group. Note that there may be multiple transaction log files that represent old transactions not yet committed to the database, but only one current log is used for each storage group.
2. ‚	C. The transaction log location is the directory in which the transaction log file for the storage group resides. By default, a location is created for the log file based on the name you give the storage group. You can change this location during creation of the storage group or any time after creation using the General property page for the storage group object.
3. ‚	D. Exchange Server 2003 Enterprise Edition supports multiple public stores and multiple private stores on a single server. Exchange 2000 Standard Server supports only two stores in a single storage group. In addition, the maximum store in the Standard Edition is limited to 16 GB in size, while the Enterprise Edition allows stores of any size.
4. ‚	C. The Mailboxes container displays a list of mailboxes and some related information, such as the size of the mailbox, how many items it contains, and the time of the last logon and logoff . The Logons container shows logons to the mailbox store itself.
5. ‚	A. The Zero Out Deleted Database Pages option is used to remove all 4-KB pages of data for items when they are deleted from a database by writing zeros to these pages within all stores of the storage group. This process occurs after an online backup is performed. This option can significantly reduce server performance, though, because of the additional overhead of writing to all the pages.
6. ‚	D. When circular logging is enabled, the database engine ‚“circles back ‚½ to the oldest log file that has been fully committed and overwrites that file instead of creating a new one. This means that the log files cannot be used to re-create the database in the event of failure. In addition, incremental and differential backups cannot be used when circular logging is turned on. Finally, circular logging can be enabled only at the storage group level, since all the stores in a group share a common set of logs. The best thing to do in this scenario is to create two storage groups. Place the executive mail store into one group, and make sure that circular logging is turned off. Place the general mailbox and public store into the other storage group. You will be able to achieve only one of the optional results. If you turn off circular logging, you can use incremental backups on those stores, but you cannot limit the disk space used by the creation of new logs.

9. ‚	A, B, C, D, E. Assuming you are running in native mode, you can move a mailbox to any other store in the same organization.
10. ‚	B. The This Index Is Currently Available For Searching By Clients option on the Full-Text Indexing page for a store opens the index for searching. It is recommended that you disable this during the initial creation of the index and also during complete rebuilds of the index. Not only should you not dismount the store during indexing, but you cannot index a dismounted store. Also, there are no property pages for an index.
11. ‚	C. As transactions in transaction log files are committed to the database files, a checkpoint file ( EDB.CHK ) is updated. The checkpoint file keeps track of which transactions in the sequential list still need to be committed to a database by maintaining a pointer to the last information that was committed. This tells the engine that everything after that point still needs to be committed to a database.
12. ‚	A. By default, the databases making up the mailbox and public stores are created in \Program Files\Exchsrvr\Mdbdata .
13. ‚	C. An indexed store requires about 20 percent more disk space than a nonindexed store. Before indexing, the combined space consumed by the stores was 23 GB. Following indexing, this would increase by 20 percent, making the combined space consumed 27.6 GB.
14. ‚	B. Exchange creates two reserve log files ( RES1.LOG and RES2.LOG ) for each database. They are used if the system runs out of disk space. If that happens, Exchange shuts down the database service, logs an event to the Event Log, and writes any outstanding transaction information into these reserve log files. These two files reserve an area of disk space that can be used after the rest of the disk space is used.
15. ‚	A. In a mixed-mode organization, you can name the storage group only during its creation. Once it is created, you cannot change the name later.
16. ‚	A. You have the option of archiving all messages sent or received by users in the mailbox store to a public folder. While this does increase the use of server resources and possibly increase network traffic, it also provides a way of logging e-mail sent in your organization.
17. ‚	C. Mailboxes can be purged from the Mailboxes container in System Manager. Once a mailbox is purged, it cannot be recovered.
18. ‚	C. You can delete public stores from System Manager. However, the store cannot be the only store in an organization with a public folder tree. Also, the store must not be the default public store for any users. If the store contains any system folders, you must select a new store to hold those folders. Finally, if the store holds the only available replica of a public folder, you can still delete the store, but System Manager will warn you that the folder will be deleted as well.
19. ‚	A. Full-text indexing is enabled at the store level.
20. ‚	A. To begin with, there are no property pages for an index. The Update interval is the interval at which changes in the store are committed to the index. Decreasing this option would provide more current search results for your users. The option can be found on the Full-Text Indexing property page of the store object.
