Question 2

WEP stands for _________________________.

Accepted Answer

The answer of WEP stands for _________________________....

Question 3

____ uses TLS to authenticate the server to the client but not the client to the server.
A)PPP
B)EAP
C)EAP-TLS
D)PEAP

Accepted Answer

PEAP (Protected Extensible Authentication Protocol) uses TLS to authenticate the server to the client but not the client to the server. It provides privacy and integrity of the authentication process, but not of the subsequent data exchange. PPP (Point-to-Point Protocol) is a data link layer protocol that can be used for authentication, but does not use TLS. EAP (Extensible Authentication Protocol) and EAP-TLS (EAP with TLS) both provide mutual authentication of both the client and the server, which is not the case with PEAP.

Question 4

____ is a product for conducting wardriving attacks written by Mike Kershaw. This product is free and runs on Linux, BSD, Mac OS X, and even Linux PDAs.
A)NetStumbler
B)Kismet
C)Wardriver
D)AirSnort

Accepted Answer

Kismet is a product for conducting wardriving attacks written by Mike Kershaw. It is free and runs on Linux, BSD, Mac OS X, and even Linux PDAs. NetStumbler is a similar product but it only runs on Windows. Wardriver is generally not a specific product but a term used to describe someone who is conducting wardriving activities. AirSnort is a product used to crack WEP encryption keys, but it is not specifically for wardriving.

Question 11

____ is an enhancement to PPP.
A)EAP
B)WEP
C)WPA
D)802.1X

Accepted Answer

EAP (Extensible Authentication Protocol) is an enhancement to PPP that provides a framework for authenticating and securing network communications. It supports a range of authentication methods, including digital certificates, smart cards, biometrics, and one-time passwords. WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access) are wireless security protocols that provide encryption but are not enhancements to PPP. 802.1X is a port-based network access control protocol that can be used with EAP, but it is not an enhancement to PPP itself.
