3) Is a pseudo ‘satellite-dish’ that can pick up Wi-Fi signal from 16 kms for more.
4) A unidirectional antenna for for VHF and UHF.
5) Bidirectional antenna used for client connections.
6) Concentrated antennas used to receive at a focal point.

Question 6

Describe these types of wireless encryption:
1) 802.11i
2) WEP
3) EAP
4) LEAP
5) WPA
6) TKIP

Answer 6

1) Specifies the security mechanisms for 802.11 networks.
2) An encryption algorithm for 802.11 networks.
3) Supports multiple authentication methods such as token cards, Kerberos, and certificates.
4) A proprietary version of EAP by CISCO.
5) Advanced encryption protocol that uses TKIP and MIC.

2) Symmetric-key encryption used in WPA2 to replace TKIP.
3) Encryption protocol used in WPA2.
4) Combination of WPA2 and EAP.
5) Centralized authentication and authorization management system.
6) Protocol that encapsulates EAP within a TLS tunnel.
7) Third-generation security protocol that used GCMP-256 and HMAC-SHA-384 for encryption and authentication.

Question 8

Describe these Authentication Protocols:
1) EAP-FAST
2) EAP-TLS
3) EAP-TTLS
4) IEEE802.1X
5) WPS

Answer 8

1) Flexible authentication via protected tunnels.
2) A digital certificate needs to be signed by both ends.
3) Advanced version of EAP-TLS that uses PKI to build a secure tunnel for safe key exchange.
4) Specifies the use of EAPoL and EAPoW for authentication.
5) Used to connect wireless devices to AP/WPS-enabled routers.

Question 9

What is Open System Authentication?

Answer 9

An wireless device can be authenticated withthe AP when its WEP key matches that of the AP.

Question 10

What is Shared Key Authentication?

Answer 10

The station and the AP use the same WEP key to provide authentication.
