A wireless engineer is doing a pre-site survey. Which two attributes must match between the site survey and the production clients? (Choose two.)

AP type must match because different AP models have distinct antenna gain patterns, maximum transmit power levels, and radio capabilities that directly determine the RF coverage footprint measured during the survey.

Radio frequency band is implicitly determined by the AP type and client configuration; it is not an independent variable the engineer controls separately from the AP model selection.

Mobility patterns must match because the speed and paths clients travel through the space affect roaming thresholds, handoff timing, and the minimum overlap needed at cell edges - all of which the survey is designed to validate.

Individual user identity has no bearing on RF propagation or roaming design; what matters is the type and behavior of client devices, not who is using them.

Exact AP placement is what the pre-site survey is meant to determine - it cannot be a prerequisite for the survey itself, as production locations are not finalized at that stage.
