A. Incorrect: No such statistic is available from the shared printer properties. B. Incorrect: The % Processor Time may reach peaks of 100% for a short period of
time, which will give no indication of the average processor usage of the spooler.
C. Correct: This will give a good indication of the amount of processor time the
print spooler is taking up on the print server over the course of a normal working day.
D. Incorrect: This will examine his workstation rather than the Print Server.
Correct Answers: D
A. Incorrect: Maximum values may be unusual peaks and are not indicative of
average performance.
B. Incorrect: Current values say nothing about the average performance over a day. C. Incorrect: Minimum values say nothing about average performance over a day. D. Correct: This will give a good indication of how each subsystem is performing
over the course of the day, and Rooslan will be able to make a determination on his next course of action based upon these figures.
Correct Answers: C, D, and E
A. Incorrect: An average value of 0 is not a cause for concern. B. Incorrect: An average value of 1 is not a cause for concern; it means that the net-
work card is operating with an occasional backlog of traffic.
C. Correct: According to the explanation in the Performance console s counter sta
tistics, values of 2 or over are cause for concern and might indicate that an upgrade is necessary.
D. Correct: According to the explanation in the Performance console s counter sta
tistics, values of 2 or over are cause for concern and might indicate that an upgrade is necessary.
E. Correct: According to the explanation in the Performance console s counter sta
tistics, values of 2 or over are cause for concern and might indicate that an upgrade is necessary.

Monitor File and Print Servers
The vast majority of servers used on local area networks perform either the function of print serving or hosting file shares. For an administrator it is vitally important that these servers function efficiently and reliably. Administrators of file servers need to ensure that the volume hosting the file share does not fill with data. This can happen if old data is kept around long after it has served its use and new data is being written every day. Administrators also need to make sure that individual users do not store a disproportionate amount of data on the server com pared to their colleagues. One way of ensuring that a volume does not fill up and that all users have limits placed on their ability to store data is to institute quotas on the par tition. A quota blocks a user from using more than an allocated amount of disk space. The Quota tab can be accessed by editing the properties of an individual volume. Print queues can be monitored on the server or remotely. They can also be monitored through the Performance console. The Performance console is able to be used to gen erate an at-a-glance report of the current number of print jobs assigned to any one particular print server. This will allow an administrator to decide if the printing load should be shared among other servers if things seem to be taking an inordinate amount of time.

Objective 4.8 Questions 1.
Rooslan is the systems administrator of a medium-sized academic department at the local university. He is currently responsible for five Windows Server 2003 systems. One of these systems is used as the departmental file share with undergraduate, postgradu ate, academic, and administrative staff all using the server to share files. The file server is configured with two disks. The first disk is separated into two volumes, one of which is 10 GB and hosts the operating system, the second of which is 30 GB and hosts the undergraduate file share. The second disk comprises a single 80 GB volume that hosts the postgraduate, academic, and administrative staff file shares. Rooslan is concerned that the volumes that host this data will become full and wishes to institute disk quotas. All departmental undergraduates are members of the Undergrad group, all postgradu ates are members of the Postgrad group, all academics are members of the Academ group, and all members of administrative staff are members of the Secrat group. No user is a member of two or more of these groups. The share permissions are set so that only each individual group has access to the share. After consultation with various departmental representatives Rooslan has devised the following quota scheme: Undergraduates will be allowed to store a maximum of 100 MB of data on the server. Postgraduates will be allowed to store a maximum of 300 MB of data on the server. Members of Administrative staff will be allowed to store a maximum of 500 MB of data on the server. Members of Academic staff will be allowed to store a maximum of 800 MB of data on the server. Which of the following methods will allow Rooslan to implement his quota scheme
