Refer to the exhibit. The numbers on the floor plan represent the horizontal average lux readings for nine different room areas. Considering Cisco best practices, what can you conclude about the…

Claiming only three areas meet the requirement inverts the data; the exhibit shows six of the nine areas are within the 300-500 lux range, not just three.

Cisco recommends a horizontal average illuminance of 300-500 lux for TelePresence rooms; reviewing the nine lux readings on the floor plan shows that six areas fall within this range while exactly three do not, making B the accurate conclusion. This means the room is largely compliant but three specific areas require lighting adjustments to meet Cisco best practices.

Not all areas meet the recommended lux levels; three areas on the floor plan fall outside Cisco's 300-500 lux guideline, so this answer overstates compliance.

This answer incorrectly implies none of the areas meet the recommended levels, when in fact the majority of the nine areas are within the acceptable 300-500 lux range.
