An IS auditor should review the configuration of which of the following protocols to detect
unauthorized mappings between the IP address and the media access control (MAC) address?

A.
Simple Object Access Protocol (SOAP)

B.
Address Resolution Protocol (ARP)

C.
Routing Information Protocol (RIP)

D.
Transmission Control Protocol (TCP)

Explanation:
Address Resolution Protocol (ARP) provides dynamic address mapping between an IP address and
hardware address. Simple Object Access Protocol (SOAP) is a platform-independent XMLbased
protocol, enabling applications to communicate with each other over the Internet, and does not deal
with media access control (MAC) addresses. Routing Information Protocol (RIP) specifies how
routers exchange routing table information. Transmission Control Protocol (TCP) enables two hosts
to establish a connectionand exchange streams of data.
