Multiple answer, multiple choice

You are the network administrator of your company. You are configuring security for the wireless network of the company. You want to create a wireless network connection that uses Advanced Encryption Standard (AES) or Temporal Key Integrity Protocol (TKIP) encryption type without requiring the use of any security key or passphrase.

Which two options can you select in the Security type list on the Manually connect to a wireless network dialogue box? (Each correct answer presents a complete solution. Choose two.)

1. The WPA-Personal option.
2. The WPA2-Personal option.
3. The WEP option.
4. The WPA-Enterprise option.
5. The WPA2-Enterprise option.

Answer:

D. The WPA-Enterprise option.

E. The WPA2-Enterprise option.

Tutorial:

You can select the WPA-Enterprise option or the WPA2-Enterprise option. Windows Vista allows you to configure various types of wireless network security methods to ensure only authorized people can access your wireless network. The various wireless network security methods in Windows Vista include Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), WPA2 and 802.1x.

The WPA-Enterprise and WPA2-Enterprise security methods use 802.1x authentication and are designed for medium and large infrastructure-mode networks. When you configure your network to use WPA-Enterprise or WPA2-Enterprise security type, you are not required to enter any security key or passphrase. Selecting a WPA network security type allows you to select AES or TKIP encryption type. AES provides more secure encryption than its predecessor Data Encryption Standard (DES). TKIP also is an encryption method used in WPA, which replaced WEP in Wireless Local Area Network (WLAN) products.

You should not select the WPA-Personal option or the WPA2-Personal option. The WPA-Personal and WPA2-Personal security methods use a Preshared Key (PSK) or a passphrase for authentication and are designed for small-office or home-office infrastructure-mode networks. In this scenario, you want to create a wireless network connection that uses AES or TKIP encryption type without requiring the use of any security key or passphrase. Selecting the WPA-Personal option or the WPA2-Personal option will require you to type a security key or passphrase.

You should not select the WEP option. WEP is an open system authentication that is a widely used network security method. You are required to set up a network security key when you enable WEP. This key encrypts the information that one computer sends to another computer across your network. WEP network security method does not allow you to use AES or TKIP encryption type. Therefore, selecting the WEP option will not be useful.

Multiple answer, multiple-choice

You are using Windows Mail on your Windows Vista computer. You want to send an e-mail using certificate to prove your identity to the recipient. What is the correct method to send an e-mail using a certificate? (Choose two. Each option is a complete answer.)

1. While composing an e-mail message, click the Tools menu, and then click Encrypt.
2. While composing an e-mail message, click the Encrypt message button on the toolbar in the New Message window.
3. While composing an e-mail message, click the Tools menu, and then click Digitally Sign.
4. While composing an e-mail message, click the Digitally Sign message button on the toolbar in the New Message window.

Answer:

C. While composing an e-mail message, click the Tools menu, and then click Digitally Sign.

D. While composing an e-mail message, click the Digitally Sign message button on the toolbar in the New Message window.

Tutorial:

The option stating, “While composing an e-mail message, click the Tools menu, and then click Digitally Sign.” is correct. Digital IDs are referred to as certificates. You can send an e-mail using a digital ID from Windows Mail that allows the recipient to verify that an e-mail was actually sent by you. You can also use a digital ID to encrypt messages, keeping them private.

Encrypted messages are messages signed with a digital ID that you can send in a scrambled format so it can only be read by your recipient. However, you and the recipient must have copies of each other's digital ID to be able to send and read encrypted messages.

The option stating, “While composing an e-mail message, click the Digitally Sign message button on the toolbar in the New Message window.” is correct. You can add a certificate to a new message in Windows Mail by selecting the Digitally Sign option on the Tools menu or by clicking the Digitally Sign message button on the toolbar in the New Message window.

The option stating, “While composing an e-mail message, click the Tools menu, and then click Encrypt.” is incorrect. You can send an encrypted message by using these steps. However, before sending an encrypted message, you must have a digital ID in Windows Contacts for each intended recipient.

For example, when you send an encrypted e-mail message to a group of people, only those people would be able to read the message whose certificates are installed in Windows contacts, and other people will receive a prompt to provide credentials before they can read the message.

The option stating, “While composing an e-mail message, click the Encrypt message button on the toolbar in the New Message window.” is incorrect. You can send an encrypted message by using these steps. However before sending an encrypted message, you must have a digital ID in Windows Contacts for each intended recipient.
