System Design
A live sports score API is cached with Cache-Control: public, max-age=86400. What's the problem?
A
There is no problem, this is correct
B
24 hours is far longer than a live score's staleness tolerance — users could see hours-old scores with no correction mechanism short of an explicit purge
C
max-age should never be used on APIs
D
public should be no-store instead
