Juniper Mist AI collectstelemetry for Service Level Expectations (SLEs)across wired and wireless devices. This telemetry includes metrics such as time-to-connect, throughput, coverage, and switch performance.

“Service Level Expectation (SLE) data is collected from every device and stored for up toone monthin the Mist Cloud. This allows administrators to analyze historical performance trends and troubleshoot issues based on real-time and historical data.”

Option B (2 months):Incorrect — data is not retained this long.

Option C (7 days):Incorrect — telemetry retention is longer.

Option A (1 month):Correct — Mist Cloud retains SLE telemetry for30 days (1 month).

In Juniper Mist role-based access control (RBAC),site-level administratorshave limited privileges to manage devices within their assigned sites.

They cannot modify organization-level templates or global settings but can performoperational tasks, includingrebooting APs or switchesand monitoring their status.

This ensures proper delegation of duties while maintaining centralized configuration control.
