CompTIA Network+ (N10-007) — Question 12

Users are reporting issues with slow connection speeds and a loss of connectivity on the newly installed wireless network. The issues are intermittent but seem to occur most often around midday. Which of the following is the MOST likely cause?

Answer options

• A. There is interference from small appliances
• B. The signal coverage area is too small
• C. Not enough DHCP addresses have been allotted
• D. The DNS cache on the users' computers has become corrupt

Correct answer: C

Explanation

The correct answer is C because if there are not enough DHCP addresses, users will experience connectivity issues as devices try to connect to the network. While interference from appliances (A) and coverage area issues (B) can affect performance, they wouldn't specifically cause the symptoms described. A corrupt DNS cache (D) typically leads to different issues, not intermittent connectivity problems.
