CompTIA Network+ (N10-009) — Question 380

A network engineer runs ipconfig and notices that the default gateway is 0.0.0.0. Which of the following address types is in use?

Answer options

• A. APIPA
• B. Multicast
• C. Class C
• D. Experimental

Correct answer: A

Explanation

The correct answer is A, APIPA, which indicates that the device has automatically assigned itself an IP address because it could not reach a DHCP server. The other options do not apply here; Multicast refers to a specific group of addresses for sending data to multiple hosts, Class C is a range of addresses with a specific subnet mask, and Experimental addresses are reserved for testing purposes.
