Show Suggested Answer Hide Answer
Suggested Answer: B

To ensure an acceptable user experience when implementing SDP, a security architect should collaborate with IT to model and plan the user experience, client software distribution, and device onboarding processes. This is because SDP requires users to install and use client software to access the protected resources, and the user experience may vary depending on the device type, operating system, network conditions, and security policies. By modeling and planning the user experience, the security architect and IT can ensure that the SDP implementation is user-friendly, consistent, and secure.

NAC at layer 2, eh? Sounds like they're really getting down to the nitty-gritty of network security. Next thing you know, they'll be checking the devices' IDs at the molecular level.

Hmm, the data link layer, huh? That's lower down than I expected. I guess NAC needs to get its hands dirty with the hardware before it can keep the bad guys out.

Ah, I see now. The data link layer is where NAC can inspect the MAC addresses and enforce policies. Clever integration of security at that level.

I thought NAC operated at the network layer, but this explanation makes sense. The data link layer is where device authentication and access control would make the most sense.
