Categories such as “education” are useful for limiting access for specific groups of devices. For example, if one class has a particularly mischievous group who keep going off task from their devices, rules can be created to whitelist certain categories, and only pass traffic that are in these more straightforward categories. Just FYI.
Precisely. I live near Yosemite National Park, and it would be an absolute disaster if there were enough hotels, campgrounds, and amenities to meet the demand. The demand FAR exceeds its capacity for tourists, but it would destroy the very reason for that demand if that actually happened.
So what did they do? Set rules for the number of tourists allowed in the park per day, and stuck to it.
