Five Lakes Publishing has a Windows 2000 network serving 200 users. A server named User_srv is used to hold users' files. User_srv is configured with a single, large NTFS volume. Every user has a home folder on User_srv. Users can also use a shared folder named IN_PROGRESS to store files for books that are being prepared. The network administrator at Five Lakes Publishing configured disk quotas for the NTFS volume on User_srv. All users have a default limit of 100 MB, and the option to deny space to users who exceed their limit has been enabled. When a user named Amy Jones attempts to save a chapter of a new book to her home folder on the server, she receives the following error message: "The disk is full or too many files are open." What should Amy do to allow this document to be saved?

A

If any resource is not available, all resources acquired so far are released II. The resources are numbered uniquely, and processes are allowed to request for resources only in increasing resource numbers III. The resources are numbered uniquely, and processes are allowed to request for resources only in decreasing resource numbers IV. The resources are numbered uniquely. A process is allowed to request only for a resource with resource number larger than its currently held resources Which of the above policies can be used for preventing deadlock?

A

Any one of I and III but not II or IV

B

Any one of I, III, and IV but not II

C

Any one of II and III but not I or IV

Your network uses TCP/IP as the only network protocol. Devices on the network are configured to use IP address from the private 10.0.0.0 range. All the client computers on the network runs Windows 2000 Professional. The network includes Windows 2000 Server computers and UNIX servers. User's print jobs are sent to shared printers on a Windows 2000 Server computer named PrintServ that directs the print jobs to print devices attached directly to the network. You have a high-capacity print device that is attached to one of the UNIX servers. The UNIX computer uses the LPR printing protocol, and it's IP address is 10.1.1.99. The name of the printer queue is GIANT. You want users to be able to connect to this printer from their computers. What should you do?

A

Install Microsoft Print Services for Unix on PrintServ. Create a network printer on users' computers, and specify that the printer URL is LPR://10.1.1.99/ GIANT

B

Install Microsoft Print Services for Unix on users* Computers. Create a network printer, and specify that the printer name is \10.1.1.99GIANT

C

Create a network printer on PrintServ, and specify that the printer name is \16.1.1.99GIANT. Share this printer and connect to it from users computers

D

Create a local printer on PrintServ. Create a new TCP/IP port for an LPR server at address 10.1.1.99 with a queue name of GIANT. Share this printer and connect to it from users' computers
