I thought it only filtered calls, not resources?

I have a vague memory of seccomp being mentioned in the context of security, but I’m not completely confident about how it relates to resource limits.

I’m pretty certain that seccomp doesn’t limit resources like CPU or memory. It’s focused on filtering system calls, right?

I remember practicing a question about resource limits in Docker, but I’m not sure if seccomp was the right answer. I thought it was more about security.

I think seccomp is more about restricting system calls rather than directly limiting CPU or memory access. So, I’m leaning towards No.

I'm a bit confused by some of these options. I'm not sure I fully understand the differences between the Populate text field and Send keys actions. Maybe I should review the documentation on those before deciding.

I feel like statement D is also right because STS must support both HTTP and HTTPS for flexibility, though I wish I could recall more specifics.

Okay, let me review what I know about mapplets. I believe they can have target definitions and source definitions, so I'll select A and B. The other options seem a bit trickier, so I'll have to think those through more.
