A Quick Answer Key follows the Self Test questions. For complete questions, answers, and explanations to the Self Test questions in this chapter as well as the other chapters in this book, see the Self Test Appendix.
1. | You have been tasked with the implementation of enhancing the security of your network and have been allocated a modest budget to accomplish the task. You decide to implement IP Security (IPSec) between your three Windows Server 2003 servers and your Windows 2000 Professional and Windows XP Professional workstations. As the implementation proceeds, you begin hearing reports that the network does not seem as responsive. You confirm that performance has decreased. What can you do to return performance to the previous level and still accomplish your objectives?

2. | You have inherited the responsibility of supporting a server from a previous administrator. The system has dual 1 GHz CPUs, 2048MB of RAM, and a dual-channel caching hardware RAID controller with sixteen 18GB hard drives configured as a RAID 5 array. The system has been running an important SQL database for some time, but over the last few weeks, responsiveness has decreased as more people have been accessing the SQL databases. Your part-time SQL administrator has told you that recent database growth is not the culprit. The databases have been consistently using between 40 and 45 percent of the available disk space. You have been asked to resolve this problem. What can you do to increase the responsiveness of the SQL database?

3. | You have recently purchased a new single-CPU, Intel Xeon-based server. This hardware will be used to run a multithreaded CPU-intensive application. How can you ensure that the application performs at its best on the hardware provided?
|
|
4. | Your server seems slow to respond to file requests from drive D: at times. You have examined the system with Performance Monitor, and the counter LogicalDisk:Current Disk Queue Length for the D: instance consistently varies between 8 and 20 during these periods of slow response. Drive D: resides on an external, 14-slot disk array with 4 slots populated with hard drives. How should you resolve this problem?

|
5. | You have recently purchased and installed two new name-brand servers. The servers are identical in all respects, except that one server has a single CPU and the other has two. The single-CPU system will be used for basic file and print services, and the dual-CPU system will be used for running Microsoft Exchange Server. Both systems respond adequately. While developing a performance baseline, you notice that the dual-CPU system seems to be experiencing more interrupts per second than the other server. What should you do to resolve this increased level of interrupts?

6. | You have been asked to develop a backup strategy for your company’s three Windows Server 2003 servers. You have been told that the primary objective is to have the systems up and running again as quickly as possible should a disaster occur. To accomplish this goal, initial funds have been allocated and, if necessary, ongoing funds will be made available. What backup strategy should you adopt?

7. | You have been asked to develop a backup strategy for your company’s three Windows Server 2003 servers. You have been told that the primary objective is to minimize the ongoing cost of performing backups. To accomplish this goal, you have been given a modest budget. What backup strategy should you adopt?

8. | You have been asked to develop a backup strategy for your company’s three Windows Server 2003 servers. You have been told that the primary objective is to minimize the time required for performing backups on regular business days. You do not have the use of any advanced storage technology, and an older application on the server requires you to shut down the application and disable Volume Shadow Copy to get a successful backup. To accomplish this goal, you have been given a sufficient budget. What backup strategy should you adopt?
|
|
9. | Your company uses a well-known and respected third-party backup utility for all of its servers. You are adopting Windows Server 2003 early after its release and have upgraded a number of servers to the operating system. You have high hopes about improving backup performance on some of your higher volume file servers (including the ability to back up open files) and have installed the third-party client agent software on your servers. After a few days, you notice that the speed of backups has not increased. What is the most likely reason that backup performance has not increased?

10. | You have inherited the responsibility for supporting an important server recently upgraded from Windows NT 4 to Windows Server 2003. When the server was upgraded, it met the hardware requirements, but not by much. Increasing demand on the system has led to lower than desirable performance. Company management has authorized the purchase of new server hardware and would like you to upgrade the server as quickly as possible with the least amount of risk and additional expense. What is the best way to accomplish the upgrade in the fastest possible time, with the lowest risk, and no additional cost?

11. | A few weeks ago, you installed a new server. You have been performing regular full and incremental backups for all files on the system. You did not perform an initial ASR backup. When you arrived this morning, you discovered that the hard drive failed sometime last night after the backup completed, and the server will no longer boot. You replaced the failed hard drive with an identical one you had on hand. What is the quickest way to get the server back to its previous operational state?
|
|
12. | You are working on an existing server. The NIC manufacturer has notified you of an updated driver for your card that will greatly improve performance. You download and install the new driver. Before you reboot the system, you perform an ASR backup. When you reboot the system, it reaches the graphical portion of the boot process and presents a STOP message. What is the proper process for recovering from this problem?

13. | You are responsible for administering a Windows Server 2003 system. The system has a Pentium III 800 MHz CPU, 1024MB of RAM, and four hard drives configured in a RAID 5 array that reside in an external seven-slot chassis. The array is controlled by a modern, high-performance hardware RAID controller and presents the array to the operating system as a single drive. You arrive on a Monday morning to find your server has crashed. On investigation, you find that two of the hard drives failed. The server has a built-in display that tells you that one drive failed late Friday night and the second drive failed Sunday afternoon. What should you have done to prevent the second drive failure from causing the server to crash?

14. | You are replacing a single-port NIC in your server with a new four-port NIC. Your switches support 100 Mbps full-duplex operation. Your switches also support either load-balancing or failover configurations. Which configuration choice is best for increased performance and availability?
|
|
15. | Your data center recently experienced a utility power failure that took down all of the computer systems. Some systems experienced major problems (hard drive and fan failures) when the power was restored. Because of the failures, company management decides to install an Uninterruptible Power Supply (UPS) for the data center to protect the systems from another power failure. A few months later, another power failure hits the data center and the systems run for a time, then go down when the UPS runs out of power. This time, hard drive failures occur and data is lost. What was missed during the implementation of the new UPS that would have prevented the second power failure from impacting the servers?
