Which of the following protocols ensures that all relevant information is delivered to the correct access point to which the client station is associated?
A.
IAPP
B.
PPP
C.
CHAP
D.
MS-CHAP
Explanation:
IEEE 802.11F or Inter-Access Point Protocol (IAPP) is a recommendation that describes an optional extension to IEEE 802.11 and provides wireless access-point communications among multivendor systems. IAPP is required in order to ensure that all relevant information is delivered to the correct access point to which the client station is associated.Answer C is incorrect. Challenge Handshake Authentication Protocol (CHAP) is an authentication protocol that uses a secure form of encrypted authentication. Using CHAP, network dial-up connections are able to securely connect to almost all PPP servers.
Answer B is incorrect. The Point-to-Point Protocol, or PPP, is a data link protocol commonly used to establish a direct connection between two networking nodes. It can provide connection authentication, transmission encryption privacy, and compression. PPP is commonly used as a data link layer protocol for connection over synchronous and asynchronous circuits, where it has largely superseded the older, non-standard Serial Line Internet Protocol (SLIP) and telephone company mandated standards (such as Link Access Protocol, Balanced (LAPB) in the X.25 protocol suite). PPP was designed to work with numerous network layer protocols, including Internet Protocol (IP), Novell’s Internetwork Packet Exchange (IPX), NBF, and AppleTalk.
Answer D is incorrect. Microsoft Challenge Handshake Authentication Protocol version 2 (MS-CHAP v2) is the new version of MS-CHAP. MS-CHAP v2 provides the highest level of security and encryption for dial-up connection in the environment consisting of both Windows NT and Windows 2000/XP dial-up clients. It provides mutual authentication, stronger initial data encryption keys, and different encryption keys for sending and receiving data.Reference. http.//isbnlib.com/preview/0470438916/CWSP-Certified-Wireless- Security-Professional-Official- Study-Guide-Exam-PW0-204-
