Juniper Mist AI, Associate Exam JN0-251 JNCIA-MistAI Exam Questions

Answer : D

According to the web search results, the LED on a Mist AP can be used for antenna orientation in the location design phase, besides providing AP configuration status.The location design phase is the process of planning and deploying a wireless network that can provide accurate and reliable location services, such as indoor positioning, wayfinding, or asset tracking1.Antenna orientation is an important factor that affects the performance and accuracy of location services, as it determines the coverage and signal strength of the APs2.

The LED on a Mist AP can be used to indicate the antenna orientation by showing different colors and patterns depending on the angle of the AP3.For example, a blue LED means that the AP is facing down, a green LED means that the AP is tilted at 45 degrees, and a red LED means that the AP is facing up3.By using the LED as a guide, the network installer can easily adjust the angle of the AP to achieve the optimal coverage and location accuracy3.The LED can also be controlled remotely by using the Mist AI app or the Mist portal3.

Therefore, based on the web search results, the LED on a Mist AP can be used for antenna orientation in the location design phase, besides providing AP configuration status.This feature can help improve the quality and efficiency of location services in various scenarios, such as retail, hospitality, or healthcare1.

Answer : D

If you want to enable a feature that is only available on Release Candidate 1, you need to upgrade your AP to the latest firmware version that supports that feature.To do that, you can use the Firmware Upgrade feature in the Mist GUI, which allows you to automatically or manually upgrade multiple APs on your site1. To find out which version of Release Candidate 1 is available for your AP, you can go to Support Tickets and Documentation -> Firmware Updates in the Mist GUI.There, you will see a list of the latest firmware versions for different AP models, along with the release notes and the features they support2.You can also use the ? mark in the upper right of the UI to see the latest firmware and previous production releases1.You can then select the desired firmware version from the dropdown menu and start the upgrade process1.

Answer : A, C

A microservice can be added without system downtime. This is because microservices are independent and loosely coupled components that communicate over well-defined APIs. Adding a new microservice does not affect the functioning of other existing microservices or the overall application.The new microservice can be deployed and integrated seamlessly with the rest of the system1.

A microservice can be updated without system downtime. This is because microservices allow each service to be developed, tested, and deployed independently of other services. Updating a microservice does not require changing or restarting the entire application.The updated microservice can be rolled out gradually or reverted easily if needed2.

Answer : C, D

According to the web search results, the two APIs that are supported by Mist are webhook and REST.A webhook is a way of sending data from the Mist cloud to a third-party application or service when a certain event occurs1.A webhook can be used to integrate Mist with various platforms, such as Slack, Splunk, ServiceNow, or Zapier1.A webhook can also be used to trigger custom actions, such as sending notifications, creating tickets, or updating databases1.You can configure webhooks in the Mist portal by selecting the organization, site, and event type that you want to send data to1.

A REST (Representational State Transfer) is a way of accessing and manipulating data from the Mist cloud using HTTP requests and responses2.A REST API can be used to perform various tasks, such as creating and managing organizations, networks, sites, devices, users, and policies2.A REST API uses JSON or XML as the data format and supports different HTTP methods, such as GET, POST, PUT, and DELETE2.You can use the REST API to automate and customize your Mist environment according to your needs2.You can access the REST API documentation in the Mist portal by clicking on the ? mark in the upper right of the UI2.

Answer : D

According to the web search results, the Marvis Action category that will detect a bad cable based on information and behavior of a single AP is Switch1.The Switch category lists the issues related to the switches that are connected to the Mist APs, such as missing VLANs, L2 loops, or bad cables1.The bad cable action detects if an AP is connected to a switch port that has a faulty cable, which can cause packet loss, CRC errors, or link flaps1.The bad cable action is based on the information and behavior of a single AP, such as the AP's MAC address, IP address, switch port, and link status1.The bad cable action also provides a recommended solution, which is to replace the cable or use another switch port1.

Answer : C

The Juniper Mist cloud delivers a modern microservices cloud architecture to meet your digital transformation goals for the AI-Driven Enterprise1.Machine learning is one of the key technologies that enables the cloud to automate key tasks and proactively address networking issues before they impact the quality-of-service levels2.Microservices are a way of designing software applications as a collection of independently deployable, small, modular services, each running a unique process and communicating through APIs3. This allows for faster and more scalable development, deployment, and maintenance of cloud services.

Answer : C

According to theMist Access Pointspage, the BT11 is a dedicated device for location-based services (LBS) in the Mist Access Point portfolio1.The BT11 is a battery-powered Bluetooth Low Energy (BLE) beacon that can be used to enhance the accuracy and reliability of indoor location services1.The BT11 can be placed in areas where Mist APs are not available or where additional BLE coverage is needed1.The BT11 can be managed by the Mist cloud and integrated with the Mist AI platform for analytics and automation1.
