Your network contains a wireless access point. You have a computer that runs Windows 7. The computer connects to the wireless access point. You disable Service Set Identifier (SSID) broadcasts on the wireless access point. You discover that you are now unable to connect to the wireless access point from the Windows 7 computer. You need to ensure that the computer can connect to the wireless access point.
What should you do?
A . From Credential Manager, modify the generic credentials.
B . From Credential Manager, modify the Windows credentials.
C . From Network and Sharing Center, turn on Network discovery.
D . From Network and Sharing Center, modify the wireless network connection settings.
Answer: D
Explanation:
Wireless Network Connection settings
To connect to a wireless network that does not broadcast its SSID, you need to know details such as the network name and security type. In Network And Sharing Center, you click Set Up A Connection Or Network, click Manually Connect To A Wireless Network, and click Next. You are prompted for the network name and security type and (if appropriate) encryption type and security key. Alternatively, you can open an elevated command prompt and enter a command with the following syntax: netsh wlan connect name=<profile_name> ssid-<network_ssid> [interface=<interface_name>] (Since the computer has previously been connected, just modify the settings.)
NOT Network Discovery
Network Discovery allows the client running Windows 7 to locate other computers and devices on the network. It also makes the client visible to other computers on the network. Disabling Network Discovery does not turn off other forms of sharing.
NOT Credential Manager
Credential Manager stores logon user name and passwords for network resources, including file servers, Web sites, and terminal services servers. Credential Manager stores user name and password data in the Windows Vault. You can back up the Windows Vault and restore it on other computers running Windows 7 as a method of transferring saved credentials from one computer to another. Although Credential Manager can be used to back up some forms of digital certificates, it cannot be used to back up and restore the self-signed Encrypting File System (EFS) certificates that Windows 7 generates automatically when you encrypt a file. For this reason, you must back up EFS certificates using other tools. You will learn about backing up EFS certificates later in this lesson.
