CompTIA Network+ (N10-009) — Question 420

An organization recently connected a new computer to the LAN. The user is unable to ping the default gateway. The technician examines the configuration and sees a self-assigned IP address. Which of the following is the most likely cause?

Answer options

• A. The DHCP server is not available.
• B. An RFC1918 address is being used.
• C. The TCP/IP stack is disabled.
• D. A static IP is assigned.

Correct answer: A

Explanation

The most likely reason for the computer receiving a self-assigned IP address is that the DHCP server is not available to assign a proper IP address. The other options are less plausible; an RFC1918 address would still be valid on the LAN, a disabled TCP/IP stack would prevent network connectivity entirely, and a static IP assignment would typically not result in a self-assigned address.
