CompTIA Network+ (N10-009) — Question 357

While deploying a new fleet of computers on a DHCP network, a network administrator notices that new computers cannot connect to the internet. Which of the following is most likely the problem?

Answer options

• A. Incorrect default gateway
• B. Address pool exhaustion
• C. Duplicate IP address
• D. Incorrect subnet mask

Correct answer: B

Explanation

The correct answer is B, as address pool exhaustion means that the DHCP server has run out of IP addresses to assign, preventing new devices from connecting to the network. The other options, while potentially problematic, do not directly account for the inability of new computers to acquire an IP address from DHCP.
