You are the Cisco Network Designer for a Company. Which of these are important when determining how many users a NAS can support? (Select three)
The correct answer is A. Total number of network devices B. Number of checks in each posture assessment D. Number of plug-ins per scan. When sizing a Cisco NAS for user capacity, the processing load is determined by how many devices connect, how complex each posture check is, and how many plug-ins run per scan. Bandwidth is a network transport concern, not a NAS capacity factor.

Why each option
When sizing a Cisco NAS for user capacity, the processing load is determined by how many devices connect, how complex each posture check is, and how many plug-ins run per scan. Bandwidth is a network transport concern, not a NAS capacity factor.
The total number of network devices directly determines the authentication and posture evaluation workload placed on the NAS, affecting how many concurrent sessions it must handle.
Each posture assessment check consumes processing resources on the NAS; more checks per assessment reduce the number of simultaneous users the NAS can evaluate.
Bandwidth is a characteristic of the network infrastructure, not a processing constraint of the NAS itself, so it does not determine how many users the NAS can support.
Each plug-in executed per scan adds CPU and memory overhead on the NAS, so the plug-in count per scan directly limits the number of users that can be assessed concurrently.
