Wireless Network Security

You are a Network Administrator for McNeil Inc. The company operates a Windows Server 2008 network environment. The network is configured as a Windows Active Directory-based, single-forest, domain-based network. Company management has decided to provide laptops to sales team members. These laptops have smart-card readers and will be configured as wireless network clients. You must accomplish the following tasks:

  • Secure wireless network communications.
  • Allow laptop users to use smart cards for authentication.

To accomplish these tasks, you take the following actions:

  • Configure 802.1x and WEP for the wireless connections.
  • Configure the PEAP-MS-CHAP v2 protocol for authentication.

What will occur after you take these actions?

  • A The laptop users will be able to use smart cards for getting authenticated.
  • B Both tasks will be accomplished.
  • C None of the tasks will be accomplished.
  • D The wireless network communication will be secured.
Explanation

PEAP-MS-CHAP v2 uses password-based credentials rather than certificates or smart cards, so it does not provide smart-card authentication. 802.1X supplies controlled wireless access, and WEP encrypts the wireless traffic; therefore, the wireless communication security requirement is met in this configuration. Microsoft documents PEAP-MS-CHAP v2 as username-and-password authentication and identifies EAP-TLS or PEAP-TLS as the certificate/smart-card alternatives.
