The correct answer is A. Conduct a wireless survey of the back warehouse. Before selecting or installing access points in a new area, a wireless site survey must be conducted first to understand the RF environment, interference sources, and coverage requirements unique to that space.
Question
Joe, a network technician, is asked to install a couple new WAP's inside a back warehouse that was added to a main warehouse facility that already has complete wireless coverage on both the 2.4GHz and 5GHz frequencies. Joe already has a complete wireless heat map of the main warehouse. Which of the following is the first step that Joe should do before choosing which WAP's to use?
Options
- AConduct a wireless survey of the back warehouse.
- BAsk the vendor that provided the WAP's for the main warehouse for recommendations.
- CAsk the systems administrator which WAP's are preferred.
- DOnly order WAP's that support 5GHz channels.

Why each option
Before selecting or installing access points in a new area, a wireless site survey must be conducted first to understand the RF environment, interference sources, and coverage requirements unique to that space.
A wireless site survey of the back warehouse is the necessary first step because the RF characteristics of the new space - including building materials, interference sources, obstructions, and required coverage area - may differ significantly from the main warehouse. The existing heat map only covers the main warehouse and cannot be extrapolated to the new space. The survey results determine the appropriate WAP placement, quantity, transmit power settings, and which frequency bands and standards are needed, which then informs the equipment selection.
Asking the original vendor for recommendations is premature and vendor-biased before understanding the actual RF environment and coverage requirements of the new space.
The systems administrator's preference is a secondary consideration; equipment selection must first be driven by the technical requirements revealed by a site survey.
Restricting selection to 5GHz-only WAPs is a premature technical decision that may not suit the new warehouse environment, especially before surveying whether 5GHz propagation is adequate in that space.
