SubObjective: Describe and configure wireless security on Cisco clients and APs (e.g., SSID, WEP, LEAP, etc.)


Item Number: 642-845.5.1.44
Single Answer, Multiple Choice


What does Cisco recommend when implementing Cisco lightweight extensible authentication protocol (LEAP)?



  1. Server certificates
  2. Client certificate
  3. Strong passwords
  4. Password expiration

Answer:
C. Strong passwords


Tutorial:


Cisco LEAP should be deployed in conjunction with a strong password policy because it is highly vulnerable to brute force or dictionary attacks. Brute force and dictionary attacks are methods of attempting to guess passwords to gain access to a network. Strong passwords are passwords that are created to be difficult to guess.


LEAP is a password algorithm; therefore, server certificates do not apply.


Password expiration is not supported with Cisco LEAP. Therefore, this is an incorrect option.
