Wait, can redundant implementations really prevent single points of failure?

I'm a bit confused by the "always on" recording option. That doesn't seem like a security measure to me. I'll have to double-check that one.

Okay, let me break this down step-by-step. The question is asking what the "Override application menu roles" option does when configuring a module. Based on the answer choices, it seems like this option allows users to access the module even if they don't have access to the application menu. I'm leaning towards A or D, but I'll double-check the wording to make sure.
