Lesson 1 Review

Page 12-14

The Sales storage group database files are stored on a four-disk RAID-0 disk array. The transaction log files are stored on the same array. Circular logging is not enabled. You do a full backup on Monday night and an incremental backup on Tuesday night. On Wednesday at 3:00 P.M., one of the disks in the array fails. Which of the following statements is true?

You cannot retrieve any data that was written to the array on Tuesday or Wednesday.
You can restore the data up to the Tuesday night backup.
You can restore the data backed up on Tuesday night and then do a roll-forward to restore data up to 3:00 P.M. on Wednesday.
You do not need to restore data. It is on a fault-tolerant array.

Which storage technology typically has its own IP address?

RAID
SAN
ESA
NAS

Your transaction log files are held on a four-spindle RAID-0+1 disk array. Disks A and B form a striped volume, as do disks C and D. The two striped volumes are mirrored. Disk A experiences a hardware failure. While replacing Disk A, your assistant accidentally damages Disk B. How do you recover from this situation?

Answers

1.	The correct answer is b.
2.	The correct answer is d.
3.	Because Disks A and B are both on the same side of the mirror, a copy of all the transaction log files is held on the undamaged Disks C and D. You need to replace Disks A and B and ensure that all data from the volume implemented by C and D is copied to the volume implemented by A and B when you re-create the mirror. It would be wise to first back up the transaction log files, if you have not already done so.

Lesson 2 Review

Page 12-26

1.	You store your databases and transaction log files on different hard disks. Circular logging is not enabled. You perform a differential backup every weekday night. Over the weekend, you perform a copy backup and archive the tape. It is taking longer each night to perform your differential backup and you are receiving warnings that the hard disk containing your transaction log files is nearing capacity. How do you deal with the situation?
2.	You decide to use third-party backup software that uses the shadow copy method. You do not want to perform offline backups, and you want to ensure that your backed up databases are consistent. What do you need to check, and what step do you need to take?
3.	What do you need to do to ensure that your Exchange Server 2003 organization can recover from the failure of a quorum disk resource?

Answers

1.	Perform a full backup. This will truncate your transaction log files. Because neither a copy nor a differential backup deletes committed transaction log files, undeleted files are filling your disk. You also need to revise your backup strategy and implement periodic full backups.
2.	You need to check that the third-party backup software supports Microsoft VSS. You need to enable this service on your Exchange Server 2003 servers and set the startup type to automatic.
3.	To enable recovery from a failure in the quorum disk resource, you need to perform either a full computer backup or a Windows backup on the node that owns the quorum disk resource.

Lesson 3 Review

Page 12-44

1.	You want to restore three storage groups, each of which contains five databases. How many restore operations do you need to perform?
2.	Your Exchange Server 2003 organization has a dedicated public folder server. You want to restore a single public folder store from backup. What difficulty do you face, and how do you accomplish your goal?
3.	You have backed up system state data on a domain controller. What must you do to restore this data?
4.	What happens to the Exchange Server 2003 resources running on a single node in a cluster if that node fails?

Answers

1.	Three. Because each storage group is a backup set and log files are shared, it is best to perform one restore per storage group at a time. You can restore multiple stores in a storage group simultaneously.
2.	If you restore a single public folder store from backup, then not only will you restore the public folder that you are trying to recover, but you will also replace all the other existing public folders with the information contained in the backup set. If you have a dedicated public folder server, then you need to use a recovery server to restore the public folder from backup media.
3.	You restart the domain controller and press the F8 key when the server is booting. You select to boot into Directory Services Restore mode and perform a restore operation in that mode.
4.	When a single node in a cluster fails, the Exchange Server 2003 resources running on that node are moved to another available node in the cluster. Exchange databases remain intact on shared storage and can be accessed by the Exchange virtual server from another node in the cluster.

Case Scenario Exercise: Requirement 1

Page 12-46

1.	Your chief executive officer (CEO) knows that you can do online backups but that mailbox stores need to be dismounted in order to restore data. She is also convinced about the value of trial restores. Previously, you have used recovery storage groups to restore test your restore process, but this is not seen as a totally satisfactory solution as data cannot be restored to exactly the same mailbox store unless you dismount that mailbox store. What do you tell the CEO?
2.	Your CIO wants to know how you intend to configure an Exchange server in a different Active Directory forest when Tailspin Toys has only one forest. He also wants to know whether this server will be physically connected to the Tailspin Toys network. What do you tell him?

Answers

You intend to create a recovery server. The recovery server will contain mailbox stores with exactly the same configuration as the stores in your current organization. You can perform trial restores on the recovery server without disrupting service to the Tailspin Toys Exchange organization.

Tip

Recovery storage groups are described in Chapter 14, "Troubleshooting Microsoft Exchange Server 2003."

To create a recovery server, you need to configure an Exchange Server 2003 server in a different forest from your Exchange organization. Because you do not have another forest, you need to promote the server to a domain controller. The computer can be connected physically to your network.

Case Scenario Exercise: Requirement 2

Page 12-46

1.	You need to recover a mailbox that was deleted six months ago. What information do you need to obtain about that mailbox?
2.	What tool can you use to edit the properties of the configuration container on your recovery server in Active Directory?

Answers

1.	You need to know the LegacyExchangeDN attribute of the administrative group that contains the mailbox you want to recover. The LegacyExchangeDN values for /O=<Organization name> and /OU=<Site name> in the configuration container in Active Directory on the recovery server must match the LegacyExchangeDN attributes of your production server.
2.	You can use the Active Directory System Interface (ADSI) Edit tool to edit these properties.

Case Scenario Exercise: Requirement 3

Page 12-47

1.	Your CIO requires proof that you can restore both public and private stores from backup. What proof can you give him?
2.	Your CIO wants reassurance that you can restore a specified public folder in a public store without replacing the information in all the other public folders. What do you tell him?

Answers

When you have configured the recovery server, you can restore public and private stores to that server. You can do this without disrupting Tailspin Toys's e-mail or public store services.

If you attempt to restore a public folder on the same public store server then you also replace all the other existing public folders with the information contained in the backup set. This difficulty is reduced if you create a replica of the folder on another server, which allows you to replicate a copy of the public folder to the server where it was lost. Where you have a dedicated public folder server and cannot replicate a copy of the public folder on another server in your Exchange Server 2003 organization, then you need to use a recovery server to restore the public folder. You can then export the public folder data to a .pst file that you can load into your profile on the production server.
