Three of the 98 questions in this pack
Question 1
You are asked to display your network devices using the Juniper Mist GUI as a single solution. Your network is made up of a wireless infrastructure of only Juniper APs and the wired infrastructure has a mix of Juniper and non-Juniper switches. Your solution must ensure that all devices are displayed in the Juniper Mist GUI.
Given this scenario, how would you accomplish this task?
Show answer and explanation
Correct answer: B. Use WiFi Management and Assurance with LLDP enabled on all switches.
Juniper Mist access points learn about the switches they connect to through LLDP and report that information to the cloud. With WiFi Management and Assurance in place and LLDP enabled on every switch, the Mist portal displays the Juniper APs together with the upstream Juniper and non-Juniper switches, including details such as vendor, model, software version, AP-to-port mapping and PoE usage. This visibility is read-only for third-party switches, but it places every device in a single view without requiring the switches themselves to be adopted by Juniper Mist.
Why the other options are wrong
- A. Wired Assurance cannot adopt or manage non-Juniper switches, so a Monitoring option is not what places the third-party switches in the portal; their details come from the LLDP data that the Juniper APs report.
- C. Marvis Actions surfaces detected network issues and recommended fixes; it does not discover or display devices.
- D. Asset Visibility locates BLE tags and assets on floor plans and does not discover network switches.
Question 2
Which two statements about webhooks and APIs are correct? (Choose two.)
Show answer and explanation
Correct answer: B, D. Webhooks are a push from Juniper Mist, and APIs are a pull by the client; There is an hourly limit to the number of API calls that an organization can have.
Webhooks and APIs move data in opposite directions. A webhook is a push: when a subscribed event occurs, Juniper Mist sends an HTTP POST to the receiver URL the administrator configured, so the client does not have to ask. The REST API is a pull: the client sends requests to Juniper Mist to read or change data. API usage is rate limited, with a cap on the number of calls allowed per hour, so scripts and integrations must be written to stay within that hourly limit.
Why the other options are wrong
- A. Webhooks only deliver event notifications and cannot configure Juniper Mist objects; configuration is done through the API.
- C. Juniper Mist does not impose an hourly limit on the number of webhooks an organization can have.
Question 3
With which two external directory services does Juniper Mist Access Assurance integrate? (Choose two.)
Show answer and explanation
Correct answer: A, B. Microsoft Azure Active Directory; Okta Workforce Identity
Juniper Mist Access Assurance can query external identity providers to look up users and their group memberships for authentication and policy decisions. Microsoft Azure Active Directory (now Microsoft Entra ID) and Okta Workforce Identity are both supported directory integrations, letting administrators build access policies around existing user and group information instead of maintaining a separate user database in Juniper Mist.
Why the other options are wrong
- C. Meta Social Verify is not a directory service and is not an Access Assurance identity provider.
- D. RESTful API Fingerprinting is not a directory service; device fingerprinting is a separate function from identity provider integration.

What makes the JNCIA-MistAI hard
Like JNCIA-SEC and JNCIA-Cloud, JNCIA-MistAI has no prerequisite, and it does not touch the Junos CLI. It is the entry point to the Mist AI track, and JN0-253 is the current version. The whole exam lives in the Mist cloud dashboard and Marvis, which makes it approachable for wireless people and disorienting for router people.
The objectives start with the Mist cloud itself. Mist AI cloud and architecture covers organisations, sites and templates, and the AP claim process. Wireless assurance covers the service level expectation metrics such as time to connect, throughput and coverage. Wired assurance covers EX switch onboarding and the wired SLEs. Marvis covers the conversational assistant and its root cause workflow, and location services covers Bluetooth LE beacons and wayfinding. Cloud operations covers the Mist APIs (REST, WebSocket and webhooks) and the Juniper Mist support options. Juniper does not publish weightings or a passing score, and the questions expect knowledge of which dashboard view answers which question.
This pack has 98 practice questions for the JN0-253 JNCIA-MistAI exam.
