You are the network administrator of a small Windows 2000 Active Directory domain Ezonexam.com.The domain contains one shared print device with default settings. An employee named Tess frequently prints high-priority documents that she needs to have immediately.Tess reports missing critical deadlines because of the large number of print jobs ahead of hers in the queue.You need to ensure that Tess's print jobs are always the next to be printed, regardless of the number of other jobs waiting in the print queue.Which action or actions should you take to achieve this goal? (Choose all that reply)A. Create a new printer on the print server that points to the same print device.B. Create another print port on the print server that points to the same print device.C. In the properties of the new printer, click the Advanced tab and change the priority to 10.D. In the properties of the new printer, change the priority to 1.E. . In the properties of the original printer, click the Advanced tab and change the priority to 10.F. Configure Tess's computer to use the new printer.G. Configure the Internet Printing Protocol (IPP) Client on Barbara's computer.

There are two general approaches to attacking a (1)encryption scheme.The first attack is known as cryptanalysis.Cryptanalytic attacks rely on the nature of the algorithm plus perhaps some knowledge of the general characteristics of the ( ) or even some sample plaintext- ciphertext pairs. This type of ( ) exploits the characteristics of the algorithm to attempt to deduce a specific plaintext or to deduce the key being used. If the attack succeeds in deducing the key, the effect is catastrophic: All future and past messages encrypted with that key are compromised. The second method, known as the ( )-force attack, is to try every possible key on a piece of ( ) until an intelligible translation into plaintext is obtained. On average, half of all possible keys must be tried to achieve success.

The enable secret password appears as an MD5 hash in a router’s configuration file， whereas the enablepassword is not hashed （or encrypted， if the password-encryption service is not enabled）. What is thereason that Cisco still support the use of both enable secret and enable passwords in a router’sconfiguration？（）A、The enable password is present for backward compatibility.B、Because the enable secret password is a hash， it cannot be decrypted. Therefore， the enable password is used to match the password that was entered， and the enable secret is used to verify that the enablepassword has not been modified since the hash was generated.C、The enable password is considered to be a router’s public key， whereas the enable secret password is considered to be a router’s private key.D、The enable password is used for IKE Phase I， whereas the enable secret password is used for IKE Phase II.
