RTS/CTS is an extension to the implementation of which of the following?

  1. CSMA/CD
  2. CSMA/CA
  3. PCF
  4. SIFS

Answer(s): B

Explanation:

Request-to-Send/Clear-to-Send (RTS/CTS) - an extension to CSMA/CA, in which
clients enter into a 4-way handshake with an access point to send data. (1) Client sends RTS packet to request use of the medium, (2) if the medium is free, access point sends the CTS packet to the client, (3) client sends the DATA to the receiving client, (4) receiving client sends the ACK packet to acknowledge receipt of the DATA. 4-way
handshake = RTS-CTS-DATA-ACK

What are two methods specified by IEEE 802.11 to authenticate a user in a wireless LAN? (Choose two)

  1. Shared secrets
  2. Certificates
  3. Usernames
  4. Passwords

Answer(s): A,B

Explanation:

Use of PPTP with shared secrets is very simple to implement and provides a reasonable
level of security, especially when added to WEP encryption. Use of IPsec with shared secretsor certificates is generally the solution of choice among security professionals in this arena. When the VPN server is implemented in an enterprise gateway, the same process takes place except that, after the client associates to the access point, the VPN tunnel is established with the upstream gateway device instead of with the access point itself.
