Questions derived from the 642-845 – Optimizing Converged Cisco Networks Cisco Self-Test Software Practice Test.

 

Objective: Implement WLAN security and management
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.
