MS 70-620: Configuring network connectivity

These questions are based on 70-620 – TS: Configuring Microsoft Windows Vista Client Microsoft Self-Test Software Practice Test.

 

Objective: Configuring network connectivity
SubObjective: Troubleshoot connectivity issues

 

Multiple Answer, Multiple Choice

 

You are the network administrator of your company, and you are configuring security for the wireless network. 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 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 that 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 they 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 is also 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 pre-shared 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.
