CompTIA A+ Core 1 (220-1001) — Question 55

Which of the following is the MOST likely cause for a network PC to have an APIPA address?

Answer options

• A. DHCP failure
• B. DNS resolution
• C. Duplicate IP address
• D. Cleared ARP cache

Correct answer: A

Explanation

The correct answer is A, as an APIPA address is assigned when a device cannot obtain an IP address from a DHCP server, indicating a DHCP failure. Options B, C, and D are not directly related to the assignment of an APIPA address; DNS resolution pertains to domain name queries, a duplicate IP address would not lead to APIPA assignment, and clearing the ARP cache does not affect IP address allocation.
