You are the network administrator for TestKing. The network contains a Windows

Server 2003 computer named testking1, which hosts a critical business application

named Salesapp. Testking1 has one disk that contains a single NTFS volume.

Five days ago, the System State of testking1 was backed up, and an Automated

System Recovery (ASR) backup was created. No additional backups were

performed. Subsequently, many changes were made to the Salesapp data files.

You apply an update to the application, which requires you to restart testking1.

Windows startup terminates with a Stop error. You restart the computer and boot

to a floppy disk. A utility on this disk gives you read-only access to the NTFS file

system. You discover that one of the .dll files for the Salesapp application is

corrupted. The corrupted file is stored in the C.\Windows\System32 folder.

You need to restore the corrupted file. You need to avoid losing any changes made

to the data files on testking1.

What should you do onTestKing1？（）

You are the network administrator for TestKing. The network consists of a single

Active Directory domain. All servers run Windows Server 2003.

The domain contains two domain controllers named Testking1 and Testking2. You

use a Windows XP Professional client computer named Client1.

In Active Directory, the domain administrator creates two new user accounts

named NetAdmin1 and AdminUser1. The NetAdmin1 account is a member of the

Domain Admins global group. The AdminUser1 account is a member of only the

Users local group. You assign the AdminUser1 logon account the Allow log on

locally user right in the Default Domain Controller Group Policy object (GPO).

A new written security policy states that user accounts that are member of the

Domain Admins global group should not be used to log on to the console of a

domain controller. It also states that administrative tasks should be performed by

using the Secondary Logon service.

You need to create a new computer account in Active Directory, and you must

comply with the new company security policy.

What should you do？（）

You are a network administrator for Ezonexam.com's Windows 2000 network.

Your network has 200 Windows 2000 Professional computers and 15 Windows 2000 Server computers.

Users on the network save their work files in home folders on a network server. The NTFS partition that contains the home folders has Encrypting File System (EFS) enabled. A user named Jack Bauer leaves the company. You grant her manager the Full Control NTFS permission to Jack's home folder. When the manager attempts to open any of the files, she receives the following error message: "Access is denied."

What should you do？

A．Use System File Checker (SFC) to decrypt the file.

B．Log on the network as the Recovery Agent. Decrypt the files for the manager.

C．Log on the network as the administrator. Use the cipher command to decrypt the files.

D．Log on the network as a member of the Backup Operators group. Decrypt the files for the manager.

You are the network administrator for The network consists of a

single Active Directory domain named The domain contains Windows

Server 2003 computers and Windows XP Professional computers.

All confidential company files are stored on a file server named TestKing1. The

written company security states that all confidential data must be stored and

transmitted in a secure manner. To comply with the security policy, you enable

Encrypting File System (EFS) on the confidential files. You also add EFS

certificates to the data decryption field (DDF) of the confidential files for the users

who need to access them.

While performing network monitoring, you notice that the confidential files that are

stored on TestKing1 are being transmitted over the network without encryption.

You must ensure that encryption is always used when the confidential files on

TestKing1 are stored and transmitted over the network.

What are two possible ways to accomplish this goal？（） (Each correct answer presents

a complete solution. Choose two)
