Question
You are a network engineer at a large university. The architecture team has recently chosen Mist to replace the existing controller-based system and has replaced all the access points (APs) throughout the campus. Since the migration, users have been complaining about VoIP calls being dropped while moving between buildings. You have already validated that the APs provide appropriate coverage. Which change would help alleviate this issue?
Options
- ADeploy a Mist Edge.
- BDeploy a Session Smart Conductor.
- CDeploy a Session Smart Router.
- DDeploy additional access points.

Explanation
Mist Edge (A) solves this problem by acting as a tunnel anchor point for wireless clients. When users roam between buildings, they cross different subnets, causing their IP address to change - this breaks active VoIP sessions. Mist Edge terminates tunnels from APs and keeps the client's IP address consistent across the entire roam, preserving call state.
B (Session Smart Conductor) is the centralized management plane for Juniper's SD-WAN routers - it orchestrates SSR devices but has no role in wireless client roaming or session anchoring.
C (Session Smart Router) is a WAN-layer SD-WAN appliance designed for intelligent routing between sites, not for maintaining wireless client sessions during Layer 3 roaming.
D (additional APs) is ruled out by the question itself - coverage is already confirmed adequate, so the issue is session continuity during handoff, not signal strength.
Memory tip: Think of Mist Edge as a "sticky anchor" - without it, a roaming VoIP client is like a boat that cuts its anchor rope every time it moves to a new dock (subnet). Mist Edge keeps the rope intact across buildings.
