Free CheckPoint 156-587 R81.20 Actual Exam Questions - Question 5 Discussion

B seems off because updating the kernel cache during policy install doesn’t explain what happens immediately on a miss. The question asks for the action GW takes right then, so B doesn’t fit timing-wise.

A seems right since user space usually handles forwarding to the cloud on misses.

Makes sense that the kernel cache miss triggers something in user space, since kernel space is limited in scope. So I’d say A fits best here.

D imo. The question highlights what GW does right when the URL category isn’t found, so forwarding to CMI as the brain of inspection makes sense since it probably handles deeper checks before anything else. A and C both talk about RAD forwarding to the cloud, but that feels like a later step after inspection rather than the immediate action. B is definitely out since cache updates happen later, not instantly at the miss. So I’d go with D because it fits the idea of the system deferring to the main inspection component first.

I’m thinking it’s not B since the cache update happens later. D sounds off because CMI seems more about inspection, not forwarding. Between A and C, wouldn’t kernel space RAD mainly handle caching, and user space RAD manage cloud forwarding?

I’m ruling out B since updating the cache later doesn’t explain what happens right when the miss occurs. Between A and C, it feels like the kernel space RAD would only handle local cache stuff, not cloud forwarding—that’s probably user space RAD’s job. D mentions CMI as the brain, but I think that’s more about policy decisions, not immediate forwarding. So isn’t it more likely that the user space RAD takes over on a cache miss to forward the request to the cloud rather than kernel space RAD doing it? Does anyone have details on whether kernel space RAD can directly communicate with the cloud?

Maybe C. I doubt the user space RAD handles it directly on a miss since the kernel cache is involved; kernel space RAD forwarding to the cloud seems more immediate and fits the cache miss scenario better.

C/D? I’m thinking it’s not B because updating the kernel cache during the next policy install doesn’t really address the immediate miss. Between C and D, the “RAD in kernel space” forwarding straight to cloud seems unlikely since kernel space usually just does quick lookups. D’s idea of RAD forwarding to CMI sounds more like a control plane action, which fits better when something isn’t found locally. So I’d pick D as an alternative to A here.

A, since kernel cache misses usually trigger user space RAD actions, not kernel forwarding.

A imo, the kernel cache misses means user space RAD steps in to forward the request. Kernel space usually handles quick lookups, not forwarding directly to the cloud.

A looks right to me too. If the kernel cache misses, the user space RAD should take over and forward the request to the cloud for processing. Makes more sense than kernel space handling forwarding directly.

Maybe A makes sense because if the kernel cache misses, the user space RAD might handle forwarding to the cloud since kernel space RAD is more about quick checks.

Option C
