What are two components of WiFi Management and Assurance? (Choose two.)
- A. wayfinding
- B. Radio Resource Management
- C. Dynamic Packet Capture
- D. Marvis Actions
Answer: B,C
Explanation:
Dynamic Packet Capture and Radio Resource Management (RRM) are two key components of WiFi Management and Assurance in Juniper Mist. According to official documentation: "Dynamic packet capture allows capturing wireless packets between clients and an access point to diagnose root-cause wireless issues.
For example, when a major issue is detected, such as an authorization failure, packet captures facilitate quick troubleshooting and root-cause analysis." RRM, driven by Mist's AI, proactively analyzes network conditions and client experiences to automatically adjust channel and power settings for optimal performance: "AI- driven RRM uses data science and cumulative SLE performance to learn and optimize radio settings, helping RF planning to continue to improve and adapt in the changing environments..." Marvis Actions is an AI-powered troubleshooting feature, but it is a separate component enabled by the Marvis subscription, not by base WiFi Management and Assurance. Wayfinding is part of the vBLE Engagement or location services.
