CompTIA Network+ N10-006 Q28

A. APIPA
B. MAC
C. Static
D. Public

Correct Answer: A
Section: Network architecture

Explanation:
APIPA stands for Automatic Private IP Addressing and is a feature of Windows operating systems. When a client computer is configured to use automatic addressing (DHCP), APIPA assigns a class B IP address from 169.254.0.0 to 169.254.255.255 to the client when a DHCP server is unavailable.
When a client computer configured to use DHCP boots up, it first looks for a DHCP server to provide the client with IP address and subnet mask. If the client is unable to contact a DHCP server, it uses APIPA to automatically configure itself with an IP address from a range that has been reserved especially for Microsoft. The client also configures itself with a default class B subnet mask of 255.255.0.0. The client will use the self-configured IP address until a DHCP server becomes available.
