Passphrase

Social Sign-In

Sponsored Guest Access

Q40. What is the fundamental architectural principle of Juniper Mist that distinguishes it from legacy controller-based WLAN systems?

All access points must first be provisioned through a CLI before connecting to the cloud.

It uses a microservices cloud for management and control, while the data plane can be handled either locally at the AP or centrally via Mist Edge.

All user data traffic is required to be backhauled to the Juniper Mist cloud for processing and security inspection.

Firmware updates for access points and configuration changes are pushed from an on-premises controller appliance.

SNMP

Q48. Which two statuses are displayed on the Juniper Mist subscription page? (Choose two.)

Demo

Exceed

Valid

Active

In the Juniper Mist dashboard, managing licenses is handled through the Subscriptions page at the Organization level. This page is critical for ensuring that all deployed hardware (Access Points, Switches, and Gateways) has the necessary cloud services-such as Wi-Fi Assurance, Wired Assurance, or Marvis VNA- to function correctly. The subscription page provides a real-time overview of the organization’s licensing health using specific status indicators.
The status Active (D) indicates that the subscription is currently within its valid date range and is being utilized by the hardware in the organization. When a subscription is marked as Active, it means the features associated with that license are fully operational, and the Mist Cloud is actively processing telemetry from the associated devices. This is the primary state for all correctly provisioned licenses.
The status Exceed (B) (often displayed as “Exceeded”) is a unique and important state in the Mist ecosystem.
Unlike many legacy controllers that might shut down services if a license count is surpassed, Mist uses an
“honor-based” system combined with clear visual alerting. The Exceed status appears when the number of physical devices claimed and assigned to a site exceeds the total number of available license seats for a specific service. For example, if an organization has 100 “Wi-Fi Assurance” subscription seats but has deployed 110 Access Points, the status will show as Exceeded.
Mist provides a grace period and persistent notifications to administrators to rectify this by either purchasing more subscriptions or removing excess devices. It is important to note that while terms like “Valid” or
“Demo” might be used in general conversation, the specific operational statuses tracked in the subscription table to manage license compliance and expiration are Active, Exceeded, and Expired. These statuses allow IT teams to proactively manage their operational expenditures and ensure uninterrupted service for their wireless users.

Q49. A client device is associated with a Mist AP. The administrator wants to see a detailed chronological log of all major connection events for this specific client, including every time it associated, roamed, or failed an authentication.
