Which of the following layers are covered for network analysis using iMaster NCE-CampusInsight?

iMaster NCE-CampusInsight provides full-stack visibility by analyzing three distinct layers:

User Layer (B): Focuses on user-specific issues like authentication failures or slow associations.

Network Layer (A): Monitors device health, packet loss, and latency across the physical/logical fabric.

Application Layer (D): Identifies over 6,000 applications and analyzes the quality of experience (QoE) for key apps like Zoom or Teams.

"Protocol layer" is not categorized as a standalone analysis layer in the official HCSP V2.0 framework; protocol issues are usually nested within the Network or User analysis categories.
