CompTIA Network+ (N10-008) — Question 306

A network administrator is getting reports of some internal users who cannot connect to network resources. The users state they were able to connect last week, but not today. No changes have been configured on the network devices or server during the last few weeks. Which of the following is the MOST likely cause of the issue?

Answer options

• A. The client DHCP scope is fully utilized.
• B. The wired network is experiencing electrical interference.
• C. The captive portal is down and needs to be restarted.
• D. SNMP traps are being received.
• E. The packet counter on the router interface is high.

Correct answer: A

Explanation

The correct answer is A because if the client DHCP scope is fully utilized, new devices cannot obtain an IP address, leading to connectivity issues. Options B, C, D, and E are less likely as they do not directly explain the sudden inability of users to connect, given that there have been no recent changes to the network.
