Security: Combining Group Permissions in a Shared Folder

Mary belongs to the Accounting group and the Temps group. The AP folder, which is located on a computer running Windows XP, has the following permissions:
Accounting - Allow Modify Temps - Deny Write
The AP folder is shared and the share has the Everyone - Full Control permission.
What access to the folder does Mary have when accessing it through the network share?
1. Mary cannot access any files in the folder.
2. >>Mary can read and modify files in the folder.
3. Mary can read files in the folder.
4. Mary can read, modify, and delete files in the folder.

Explanation : Mary can read files in the folder, but cannot modify or delete them. Mary obtains the Read permission through her membership in the Accounting group. However, her membership in the Temps group revokes the Write permission that would otherwise be granted through her membership in Accounting. When a resource is accessed through a share, both the NTFS permissions and the share permissions are checked and the most restrictive set of permissions is used. In this case, the most restrictive permissions are the NTFS permissions.
Mary cannot modify files in the share because a Deny overrides any Allow and the Temp group is denied Write permission.
Mary cannot delete files in the share. The Modify permission grants the ability to read, create, and modify files. However, users can only delete their own files. Also, Mary is denied Write access so she cannot make changes to the contents of the folder.
Mary can read files in the share. This permission is assigned as part of the Modify permission.

Networks : Terminating an FTP session

When you are finished running an FTP session from the command line, which command will properly terminate your FTP session?
1. >>BYE
2. FTP
3. EXIT
4. PUT
Explanation : FTP can be initiated from a DOS, Windows 9x, or Windows NT/2000/XP command prompt provided that a connection to a network or the Internet is established first. To begin an FTP session, you first type FTP from the command line to get an FTP> prompt. To establish a connection with an FTP server at 135.61.85.1, from the FTP> prompt, type the following:
OPEN 135.61.85.1
To terminate an FTP session, simply type BYE from the FTP> prompt.

The PUT command is used after you have logged on and want to copy a file from your computer to the remote computer.

The EXIT command is used to terminate a DOS session.
After you are at the FTP> prompt, you would not use the FTP command again.

Printers and Scanners: Obtaining the Fastest Connection

Which port will give you the best performance when connecting a scanner to a computer?
1. IEEE 1284
2. USB 2.0
3. Serial
4. >>IEEE 1394
Explanation : The best performance when connecting a scanner to a computer is provided by IEEE 1394 (FireWire). FireWire 1394b provides transfer rates of more than 800 Mbps. FireWire 1394a provides transfer rates up to 400 Mbps.
USB 2.0 provides good transfer rates (up to 480 Mbps for high speed USB 2.0). However, it is not as fast as FireWire.
Scanners are typically not connected through a serial interface. A serial interface provides the slowest transfer rate.
Although you can connect a scanner using a parallel connector (IEEE 1284), doing so will result in a lower transfer rate than either USB 2.0 or IEEE 1394.

Operating Systems: Obtaining the IP address and Subnet Mask on XP

A computer running Windows XP is configured to receive an IP address automatically. Which utilities would you use to find out the IP address and subnet mask assigned to its network adapter? (Select TWO.)
1. Network Connection Status
2. WINIPCFG
3. >>IPCONFIG
4. Network Connection Properties
5. >>PING
Explanation : On a computer running Windows XP Professional, there are three ways to find out the IP address and subnet mask assigned automatically. You can run the IPCONFIG command-line utility, display Status for the network connection, or select the Adapter node under Components | Network in System Information.

You cannot obtain the IP address and subnet mask using PING. The PING utility is used to test a connection path between two computers and to test the TCP/IP stack. To test the TCP/IP stack, you ping the loopback address, which is 127.0.0.1.

You cannot obtain the IP address and subnet mask using the Network Connection Properties. If the TCP/IP properties were configured statically, you would set them and view them on the connection's Properties page. However, they are set dynamically, so you cannot view them there.

You cannot use WINIPCFG on a computer running Windows XP. WINIPCFG was a Windows 98 utility for viewing the IP address configuration.

Laptops and PDAs I

A user reports that she cannot select information on her PDA's screen. She had not used the device while she was on vacation.
What should you try first?
1. Replace the screen.
2. Replace the stylus.
3. Replace the battery.
4. >>Recalibrate the device.
Explanation : The most likely problem is that the device needs to be recalibrated. A Personal Digital Assistant (PDA) can lose its calibration if it is powered off for a long period of time. You calibrate the device by using software that prompts you to tap the boundaries of the screen so that the operating system can calculate where the stylus is pointing.

You should not replace the stylus. The stylus is a pointing device and is most likely not the cause of the problem.

You should not replace the screen before attempting recalibration. If recalibration does not work, you might need to replace the screen.

You should not replace the battery. If the battery is dead, the device will not power on. The problem the user is having is that the operating system is unable to calculate screen coordinates correctly. Therefore, the problem is either with the screen's sensitivity or with its calibration.

Components: When NOT To Wear an ESD Wrist Strap

When should you NOT wear an ESD wrist strap?
1. When replacing a network adapter
2. When installing an internal hard drive
3. When adding memory to a computer
4. >>When working with an open CRT display device
Explanation : You should not use an Electrostatic Discharge (ESD) wrist strap when working on an open Cathode Ray Tube (CRT) display. An ESD wrist strap grounds your body to protect components from an ESD shock. However, a CRT display is highly charged, so you do not want to be grounded when you work inside one. In fact, only specially trained personnel should ever open a CRT display.

You should use an ESD wrist strap when adding memory to a computer. Doing so will help protect the memory and the other components on the motherboard from an ESD shock.
You should use an ESD wrist strap when installing an internal hard drive. Doing so will help protect the hard drive and the other components you might touch from an ESD shock.

You should use an ESD wrist strap when installing a network adapter. Doing so will help protect the network adapter and the other components you might touch from an ESD shock.

Security: Upgrading and obtaining the EFS for your partition

You are upgrading a user's computer from Windows 98 to Windows XP Professional.
The computer currently has a hard disk partition formatted as FAT. The main reason for the upgrade is to allow users to secure files on that hard disk using permissions and encrypting file system (EFS).
What should you do?
1. >>Convert the hard disk to NTFS.
2. Convert the hard disk to FAT32.
3. Reformat the hard disk as NTFS.
4. Reformat the hard disk as FAT32.

Explanation : To use file permissions and EFS, you need to use the NTFS file system. You can convert the system hard disk to NTFS during installation. You can convert any hard disk from FAT or FAT32 to NTFS after installing Windows XP by using the Convert utility.
You should not convert the hard disk to FAT32. FAT32 does not support permissions or EFS.
You should not reformat the hard disk as FAT32. FAT32 does not support permissions or EFS. Also, reformatting the hard disk will cause all data stored on it to be lost.
You should not format the hard disk as NTFS. Formatting the hard disk will cause all data on it to be lost. A hard disk can be converted from FAT or FAT32 to NTFS, but not the other way around.
