Question
A cafe uses a tablet-based point-of-sale system. Customers are complaining that their food is taking too long to arrive. During an investigation, the following is noticed:

- This issue occurred when the cafe was busy.
Which of the following is the best way to mitigate this issue?

Explanation
The key clues are: (1) ALL kitchen printers failed simultaneously, (2) payments are processing correctly, (3) the cloud system received the orders, and (4) the issue only occurred when the cafe was busy. This pattern points to wireless network congestion in the kitchen area. The orders reach the cloud fine, but the local signal from the network to the kitchen printers degrades under heavy load. Adding a dedicated access point exclusively for the kitchen ensures the printers have sufficient, uncontested wireless bandwidth regardless of how many other devices are connected. Upgrading dongles (C) or assigning static IPs (D) would not resolve a congestion/signal problem, and updating the application (A) would not fix a network-layer printing failure.
