Option D makes sense to me. In SCM, reports are usually generated from dashboards you've already set up, since that's where you decide which data and widgets get included. Without configuring the dashboard first, you can't really customize what shows up in the report. Pretty sure that's how it works but open to any other ideas.
I don’t think App-ID (A) applies here, it’s User-ID (C) and Service (B). User-ID identifies the specific contractors, and Service defines what app or port they can hit, which could mean those internal apps. Only thing is, without Schedule this wouldn't restrict hours, but if the service is restricted outside business hours, maybe that's enough? Maybe missing something about time control though. Agree?
I get why some might pick D, but URL Filtering logs aren't required for IoT Security to work. B and C are the real essentials here for device profiling and threat detection. WildFire is a common trap too.
Don't think A or B work since Layer 2 isn't supported by VM-Series in Azure, that's a common trap. C is the one that fits-VM-Series for Azure with Layer 3 zones gives you segmentation and meets compliance rules. If anyone thinks Layer 2 works natively in cloud, I'd double-check that, pretty sure it's unsupported.
C
I figured Layer 2 zones on the VM-Series could handle segmentation in Azure since it lets you isolate traffic without complex routing. Maybe I’m missing something with the compliance part but A looked fine to me.
I think A makes sense here because Layer 2 segmentation should work for logically separating the network within Azure. VM-Series can be used in cloud, and Layer 2 zones let you isolate traffic. Not totally sure if Layer 3 is needed for this specific compliance ask, but A seems valid to me. Agree?
