CompTIA Network+ (N10-008) — Question 316

A network administrator has received calls every day for the past few weeks from three users who cannot access the network. The administrator asks all the users to reboot their PCs, but the same users still cannot access the system. The following day, three different users report the same issue, and the administrator asks them all to reboot their PCs; however, this does not fix the issue. Which of the following is MOST likely occurring?

Answer options

• A. Incorrect firewall settings
• B. Inappropriate VLAN assignment
• C. Hardware failure
• D. Overloaded CAM table in switch
• E. DHCP scope exhaustion

Correct answer: E

Explanation

The most likely cause is DHCP scope exhaustion, as this would prevent new devices from obtaining an IP address, leading to repeated reports of connectivity issues. The other options, while possible, would not consistently affect multiple users in different reports over consecutive days in the same manner as DHCP issues would.
