Exam Prep Questions

Question 1

You are the Web hosting administrator for your company's e-commerce environment, and you need to configure Network Load Balancing across the four Web servers running Windows Server 2003 Web Edition. The sites the servers host offers dynamic, Active Server Pages (ASP) content. Each server hosts content for different sites.

The hardware design is a multiprocessor build with redundant, hot-swappable power supplies . Each system is also installed with a hot-swappable, 64-bit, dual-port, gigabit ethernet card. (An onboard NIC is used for internal cluster communication.) Spare sets of server hot-swap hardware are locked in a cabinet in the data center's server room.

Your primary objective is to deploy Network Load Balancing across the four Web servers. Your secondary objectives are eliminating any single point of failure on the four Web servers (concerning just the servers, not the surrounding network points, such as routers) and making sure that any system hardware failures can be dealt with quickly and with limited downtime. Which of these objectives were you able to meet?

  • A. The primary objective and both secondary objectives have been met.

  • B. The primary objective and one secondary objective have been met.

  • C. The primary objective has not been met. However, both secondary objectives have been met.

  • D. Only one secondary objective has been met.

  • E. None of the objectives has been met.

A1:

The correct answer is D. For the primary objective, although Network Load Balancing is available in all editions of Windows Server 2003, the service load- balances incoming IP traffic across clusters. This scenario is concerned with Windows Server 2003 Web Edition, which does not support clustering. Also, Network Load Balancing does not support ASP pages, as they are referred to as stateful content. For Web servers, a static Web page is an example of stateless content. Network Load Balancing clusters can process these types of requests .

The first secondary objective, eliminating any single point of failure on the four Web servers, was not met because of the installed hot-swappable, 64-bit, dual-port, gigabit ethernet card. If the PCI slot the card is in should fail, it would create a single point of failure. The other secondary objective, making sure hardware failures are dealt with quickly and with limited downtime, was met by using hot-swappable equipment and having spares on site.

Question 2

You are the server administrator for your company's domain. You need to configure the Cluster Service across the four servers running Windows Server 2003 Standard Edition that are configured as Web servers.

The sites the servers host offer dynamic ASP content. The systems' hardware design is a multiprocessor build with redundant, hot-swappable power supplies. Each system is also installed with two single-port, gigabit ethernet cards and two single-port 10/100 cards for internal cluster communication. Spare sets of server hot-swap hardware are locked in a cabinet in the data center's server room.

Your primary objective is to deploy the Cluster Service across the four Web servers. Your secondary objectives are eliminating any single point of failure on the four Web servers (concerning just the servers, not the surrounding network points, such as routers) and making sure that any hardware failures on the system can be dealt with quickly and with limited downtime. Which of these objectives were you able to meet?

  • A. The primary objective and both secondary objectives have been met.

  • B. The primary objective and one secondary objective have been met.

  • C. The primary objective has not been met. However, both secondary objectives have been met.

  • D. Only one secondary objective has been met.

  • E. None of the objectives has been met.

A2:

The correct answer is C. For the primary objective, although server clusters are available in Windows Server 2003 Enterprise and Datacenter Editions, they are not available in Standard Edition. The Cluster Service does support ASP pages and other stateful content, but the primary objective has not been met.

The first secondary objective, eliminating any single point of failure on the four Web servers, is met with the two single-port gigabit ethernet cards and the hot-swappable redundant power supplies.

The other secondary objective, making sure hardware failures can be dealt with quickly and with limited downtime, is met by using hot-swappable equipment and having spares on site.

Question 3

You are the system administrator for your server environment. Your backup strategy uses one normal backup and daily incremental backups . All servers in the environment have five 18GB, SCSI3, 10,000 RPM drives and are set up using hardware RAID 5 with an online (hot) spare and a mean rebuild time of 60 minutes. The normal backup is performed each Sunday morning at 4:00 a.m. EST and takes two hours.

Incremental backups are performed each day at 10:00 p.m., Monday through Friday. No full or incremental backups are performed on Saturday. The time needed for the incremental backups varies, but it never exceeds 75 minutes.

One of the servers has a hard disk failure at approximately 6:00 p.m. on Saturday. At 6:10 p.m., a second drive in the array fails. What needs to be done to bring the server back to working order so that users can access data?

  • A. The failed drives need to be replaced and data needs to be restored from the normal backup.

  • B. The failed drives need to be replaced and data needs to be restored from the normal backup and the last incremental backup.

  • C. The failed drives need to be replaced and data needs to be restored from the normal backup and all the incremental backups.

  • D. None of these options is necessary.

A3:

The correct answer is C. When you have an online (hot) spare configuration, an extra drive is kept powered up in the array for the purpose of failover. When a drive in the working array fails, data is rebuilt onto the hot spare from the parity information and inserted into the array. The array then takes the bad drive offline, and an administrator needs to replace the drive.

In this example, one of the active drives fails and 10 minutes later, a second drive dies. Because 10 minutes is not enough time to rebuild the array from the parity information to the hot spare, the array fails. To restore the server to working order so that users can access data, the failed drives need to be replaced, and data needs to be restored from the normal backup and all the incremental backups.

When your backup strategy uses one normal backup and daily incremental backups and you have to restore the system, first you must restore the last normal backup and then restore each successive day's incremental backup.

Question 4

You are the system administrator for your server environment. Your backup strategy uses one full backup and daily differential backups. All servers in the environment have five 18GB, SCSI3, 10,000 RPM drives and are set up using hardware RAID 5 with an online (hot) spare.

The full backup is performed each Sunday at 4:00 a.m. EST and takes two hours. Differential backups are performed each day at 10:00 p.m., Monday through Friday. No full or differential backups are performed on Saturday. The time needed for the differential backups varies, but it never exceeds 75 minutes.

One of the servers has a hard disk failure at approximately 6:00 p.m. on Saturday. At 6:10 p.m., a second drive in the array fails. What needs to be done to bring the server back to working order so that users can access data?

  • A. The failed drives need to be replaced and data needs to be restored from the full backup.

  • B. The failed drives need to be replaced and data needs to be restored from the full backup and the last differential backup.

  • C. The failed drives need to be replaced and data needs to be restored from the full backup and all the differential backups.

  • D. None of these options is needed.

A4:

The correct answer is B. When you have an online (hot) spare configuration, an extra drive is kept powered up in the array for the purpose of failover. When a drive in the working array fails, data is rebuilt onto the hot spare from the parity information and inserted into the array. The array then takes the bad drive offline, and an administrator needs to replace the drive.

In this example, one of the active drives fails, and 10 minutes later, a second drive dies. Because 10 minutes is not enough time to rebuild the array from the parity information to the hot spare, the array fails. To restore the server to working order so that users can access data, the failed drives need to be replaced and data needs to be restored from the full backup and the last differential backup.

When your backup strategy uses one full backup and daily differential backups and you have to restore the system, first you must restore the last full backup, and then restore the last differential backup.

In a differential backup, the backup software does not change the archive bit's status after making the backup. Therefore, differential backups don't leave behind any signs that they were done. The next differential backup that runs backs up all files from the previous backup and any new files that have changed because only the full backup changes the archive bit. In a restore situation, therefore, you need only the full backup tape and the last differential tape.

Question 5

You are the network administrator for your Windows Server 2003 environment. You have been tasked with configuring Network Load Balancing across the four servers running Windows Server 2003 Standard Edition that are configured as file and print services.

The systems' hardware design is a multiprocessor build with redundant, hot-swappable power supplies. Each system has two single-port, token ring NICS installed for internal cluster communication. Spare sets of server hot-swap hardware are locked in a cabinet in the data center's server room.

Your primary objective is to deploy Network Load Balancing across the four servers. Your secondary objectives are eliminating any single point of failure on the four servers and making sure that any hardware failures on the system can be dealt with quickly and with limited downtime. Which of these objectives were you able to meet?

  • A. The primary objective and both secondary objectives have been met.

  • B. The primary objective and one secondary objective have been met.

  • C. The primary objective has not been met. However, both secondary objectives have been met.

  • D. Only one secondary objective has been met.

  • E. None of the objectives has been met.

A5:

The correct answer is B. The key piece of information is that Network Load Balancing is designed to work on 10Mbps, 100Mbps, and gigabit ethernet network adapters only. It is not compatible with ATM, ATM LAN emulation, or token ring networks. That means you weren't able to meet the primary objective of deploying Network Load Balancing across the four servers.

The first secondary objective, eliminating any single point of failure on the four servers, was not met because of the installed token ring cards and their incompatibility with Network Load Balancing. The other secondary objective, making sure that hardware failures can be dealt with quickly and with limited downtime, was met by using hot-swappable equipment and having spares on site.

Question 6

You are the server operator for the WLFD02 system, which is a member of the gunderville.com domain. The server is a dual-processor system running Windows Server 2003 Standard Edition and formatted with three separate partitions. The C:\ partition is NTFS, the D:\ partition is FAT32, and the E:\ partition, where shared resources are kept, is also formatted with NTFS.

You have been asked to review the frequency of tape restorations of data and the main reasons these types of restores are required on WLFD02. You have found that many of them are caused by accidental deletions by users connected to the system over the network.

You determine the restoration time for deleted data is an average of 36 hours, from the time the user who deleted the data logs the help desk ticket to the time you close the ticket after restoring the data.

Your primary objective is configuring a way for users to recover their own deleted information. Your secondary objectives are reducing data restoration time and setting up a system for users to recover their own data with the least amount of administrative effort. You have decided to enable the Shadow Copy of Shared Folders option on WLFD02 by following these steps:

Log on with your local user account, which is a member of the Server Operators group on the local system, and enable shadow copies on the C:\ and E:\ partitions.

Change the default limit of 10% for the shadow copy's total size to 5% of the available drive space.

What are the results of your actions?

  • A. The primary objective and both secondary objectives have been met.

  • B. The primary objective and one secondary objective have been met.

  • C. The primary objective has not been met. However, both secondary objectives have been met.

  • D. Only one secondary objective has been met.

  • E. None of the objectives has been met.

A6:

The correct answer is E. The Shadow Copies of Shared Folders option is enabled at the volume level only, so every shared folder on that volume is configured to use this feature after it is set. The shadow copy configuration is also set for the entire volume.

The primary objective has not been met because you are not logged in as an administrator. Logging in with any other level of access means you can't see the Shadow Copies tab in the volume's Properties dialog box. Because you cannot enable this option, your secondary objective of reducing data restoration time has not been satisfied. The other secondary objective, setting up the primary objective with the least amount of administrative effort, has not been met, either. Volumes configured with the Shadow Copy service need to be formatted with NTFS.

The default setting for volume space reserved for shadow copy use is 10% of the total volume size (not 10% of the volume's free space). Administrators can change this setting, too, but setting the limit too low causes the oldest shadow copies to be deleted regularly, often much sooner than the maximum number of shadow copies allowed per volume, because the volume's reserved space is being used up.

Question 7

You are the server administrator for the WLFD07 system, which is a member of the gunderville.com domain. The server is a single-processor system running Windows Server 2003 Standard Edition and formatted with three separate partitions. The C:\ partition is NTFS, the D:\ partition is FAT32, and the E:\ partition, where shared resources are kept, is also formatted with NTFS.

You have been asked to review the frequency of tape restorations of data and the main reasons these types of restores are required on WLFD07. You have found that many of them are caused by accidental deletions by users connected to the system over the network.

You determine the restoration time for deleted data is an average of 48 hours, from the time the user who deleted the data logs the help desk ticket to the time you close the ticket after restoring the data.

Your primary objective is configuring a way for users to recover their own deleted information. Your secondary objectives are reducing data restoration time and setting up a system for users to recover their own data with the least amount of administrative effort. You have decided to enable the Shadow Copy of Shared Folders option on WLFD07 by following these steps: Log on with your local user account, which is a member of the Administrators group on the local system, and enable shadow copies on the C:\ and E:\ partitions.

Change the default limit of 10% for the shadow copy's total size to 5% of the available drive space.

What are the results of your actions?

  • A. The primary objective and both secondary objectives have been met.

  • B. The primary objective and one secondary objective have been met.

  • C. The primary objective has not been met. However, both secondary objectives have been met.

  • D. Only one secondary objective has been met.

  • E. None of the objectives has been met.

A7:

The correct answer is B. You have met the primary objective because you logged in as an administrator to enable the feature on the system. You also met the secondary objective of reducing data restoration time because shadow copies are an easier way for users to retrieve previous versions of their files than relying on data restoration via backup media.

However, you didn't meet the other secondary objective of setting up a user restoration method with the least amount of administrative effort because you went through the extra step of enabling shadow copies on the C:\ partition. The data that required shadow copying is located only on the E:\ partition, so there was no reason to enable this option on the C:\ partition.

Question 8

You are the network administrator for zandri.net , which is a Windows Server 2003 native mode domain. You have been reviewing the steps for installing the Cluster Service on a pair of systems that are already running Windows Server 2003 Standard Edition. Your staff has already gathered the following information for you:

Only a user account logged on as an administrator can perform the installation.

One specific node should be selected for the initial installation.

During the installation, the second node must be powered on to ensure that the shared drive array is "aware" that multiple servers will access the drive.

Your staff has not been able to successfully deploy the Cluster Service on these systems. Which of the following reasons are the most likely explanation for this failure?

  • A. The issue is that there is only a pair of servers for the cluster; no fewer than four systems should be in use.

  • B. The issue is with the second node being powered on.

  • C. The issue is with Windows Server 2003 Standard Edition.

  • D. The issue is with using the Administrator account; the account used must be a Domain Administrator account.

A8:

The correct answer is C. The key reason this installation will not succeed is the operating system; Windows Server 2003 Standard Edition does not support clustering, so answer A is not correct. Installation must be performed by a user account logged on as an administrator, so answer D is not correct. One specific node should be selected for the initial installation.

During the installation, the second node must be powered off to ensure that the shared device does not become corrupt because of multiple computers accessing the drive, so answer B is not correct.

Question 9

You are the network administrator for zandri.net , which is a Windows Server 2003 native mode domain. You are currently troubleshooting a cluster configuration in your testing environment that is having intermediate failure issues.

Your four servers are running Windows Server 2003, Enterprise Edition. They are all running 933MHz processors (two per system) and are configured with two dual-port PCI add-on NICs and one NIC on the motherboard. The network cards for the public network are set up and enabled to auto-detect the network speed, as are the onboard NICs.

The main problem you are having with the cluster is that live nodes are being knocked offline and losing access to their resources. The Event Viewer logs show that at certain points in the day, two nodes are attempting to control the same resource. The logs also show lost heartbeat messages for nodes that are actively participating in cluster operations and listed as UP in the cluster manager.

The problem occurred more often on an older version of the network drivers (version 5.5) for the add-on cards. You have updated them to the recommended version, 5.56. A new version of the network card driver, 5.75, is available, but it has not been tested on Windows Server 2003. A firmware revision is also available for the system motherboard.

Which of the following course of actions should you attempt next?

  • A. Proceed with the firmware revision for the system motherboard.

  • B. Update the PCI NIC drivers in each node to version 5.75 only.

  • C. Configure each adapter in each node to the same values (Duplex Mode, Flow Control, and Media Type), and update the drivers to version 5.75.

  • D. Configure each adapter in each node to the same values (Duplex Mode, Flow Control, and Media Type). Do not update the drivers to version 5.75.

A9:

The correct answer is D. The properties of each adapter in each node (Duplex Mode, Flow Control, and Media Type) should be set to the same values and should not be set to auto-detect the network speed. If the adapters are allowed to detect the speed, some adapters might drop network packets while trying to determine the speed, and the incorrect speed, which is incompatible with some network hardware, might be used.

Having NICs set to auto-detect has the potential of disrupting network traffic to the clusters, and on the heartbeat network, it can cause intermittent network failures that could result in one node thinking another active node has gone offline, which could result in systems fighting over resources.

Also, you do not want to make two changes at once, such as changing the settings and updating the drivers. Updating the drivers alone did not correct the problem before, and the drivers have not yet been tested on Windows Server 2003, so this action is not recommended.

Question 10

You are the network administrator for zandri.net , which is a Windows Server 2003 native mode domain. You have identified four of your Windows Server 2003 systems to be installed as nodes and domain controllers of their own domain. What is the best way to configure these systems?

  • A. Configure a domainlet.

  • B. Configure the servers in a workgroup first and then add each one into one domain.

  • C. Configure the servers in a workgroup first and then add each one into different domains.

  • D. Configure the servers in a workgroup and add computer accounts for them in a single domain. Edit the network identification for each node so that each has a corresponding network ID to the domain where its account exists.

A10:

The correct answer is A. Clustering should be enabled on nodes that are member servers in the same domain with access to a domain controller. If any node needs to be configured as a domain controller, all nodes should be configured as domain controllers.

If you want nodes to be domain controllers of their own domain, it is better to configure a domainlet. Domain controllers in the domainlet do not have to authenticate users or provide global catalog lookup services to users or computers. The domainlet includes only well-known policies and groups defined for all domains, such as Administrators, Domain Administrators, and service accounts required by the clusters it supports.
