NEW QUESTION 15
Click the Exhibit button. The exhibit displays the connection flow for an API interaction sequence.
Which API type is displayed?

SOAP

WebSocket

Webhook

RESTful

The diagram displays the concept of a webhook interaction.
The client sends an initial request to the server (Step 1: Request/Response).
After that, the server asynchronously sends events or updates to the client (Steps 2 and 3: Event notifications), without requiring the client to poll for updates continuously.
This asynchronous “push” behavior is characteristic of webhooks, where the server pushes updates to the client.

NEW QUESTION 16
Which step must you take when configuring rogue AP detection?

Enable rogue AP detection.

Set the proximity zones.

Disable honeypot detection.

Set the Radio Resource Management (RRM) interval.

Rogue AP Detection:
Rogue AP detection is crucial for maintaining network security by identifying unauthorized access points.
Configuration Step:
Enable Rogue AP Detection:
The first and necessary step in configuring rogue AP detection is enabling the feature in the Mist system.
Other Steps:
Setting proximity zones, disabling honeypot detection, and setting the RRM interval are additional configurations but not the initial or mandatory step.

NEW QUESTION 17
Which two statements are correct about Juniper Mist Wired Assurance ZTP? (Choose two.)

The cloud-ready Juniper switch must either boot from the factory-default state or you can issue the request system zeroize Junos command to reset the configuration.

The switch must be running a supported Junos version for Juniper Mist Wired Assurance.

All legacy Juniper switch models are supported.

The technician must have console access to the switch during the initial setup.

Supported Junos Version: For Juniper Mist Wired Assurance to function correctly, the switch must be running a supported Junos version. This ensures compatibility with Mist’s cloud management and AI capabilities.
Factory-Default State or Zeroize Command: The switch must boot from a factory-default state, or you can use the request system zeroize command to reset its configuration. This is essential for seamless onboarding and auto-provisioning.

NEW QUESTION 18
Under Marvis Actions, what is required for Marvis to provide a visualization of low coverage and low-capacity issues within the network?

a Premium Analytics subscription

a cloud-ready switch

a floor plan

a WAN edge device

For Marvis, Mist AI’s virtual network assistant, to provide a visualization of low coverage and low- capacity issues within the network, a floor plan is required. This enables Marvis to map the coverage and capacity data to specific locations within the physical space, allowing for precise identification and troubleshooting of network issues.

NEW QUESTION 19
You want to troubleshoot a wireless client that is no longer connected to a Mist AP.
Which area within the Mist GUI would you use?

Monitor -> Service Levels -> Insights

Organization -> Audit Logs

Clients -> WiFi Clients

Clients -> App Clients

To troubleshoot a wireless client that is no longer connected to a Mist AP, you would navigate to the “Clients” section within the Mist GUI and select “WIFI Clients.” This area provides detailed information about all wireless clients that have connected to the Mist APs, including their connection history, performance metrics, and any issues encountered. By examining the data available in the WIFI Clients section, network administrators can identify the root cause of connectivity problems and take appropriate actions to resolve them.

NEW QUESTION 20
Which Mist supported API is considered data-driven?

RESTful

Webhook

WebSocket

gRPC

NEW QUESTION 21
Which two statements correctly describe Mist claim codes and activation codes? (Choose two.)

An activation code is printed on a sticker on the AP.

Activation codes may be used to claim multiple APs at once.

Claim codes may be used to claim multiple APs at once.

Claim codes may be used to claim only one AP.

Claim Codes: Claim codes are unique to each AP and can be used to claim only one AP at a time. This ensures each device is correctly registered and managed individually within the Mist system.
Activation Codes: Activation codes can be used to claim multiple APs at once, facilitating bulk onboarding and simplifying the setup process for large deployments.

NEW QUESTION 22
Which Mist API is event driven?

Webhook

Python

RESTful

FTP

Event-Driven API: Webhooks are used as an event-driven API in Mist. They allow the system to send real-time notifications to external systems when specific events occur, enabling immediate actions or alerts.

NEW QUESTION 23

NEW QUESTION 31
You scheduled downtime to push the latest firmware to all the APs you deployed at the site. You verified that all of the APs are working fine. When you go back to work, you notice no complaints from the users. When you check the AP page, you notice that several APs have not rolled out with the latest firmware.
In this scenario, how does Marvis categorize this issue in the Marvis Action dashboard?

The non-compliant Marvis Action is displayed.

The high CPU Marvis Action is displayed.

The missing VLAN Marvis Action is displayed.

The port flap Marvis Action is displayed.

When several APs fail to update to the latest firmware during a scheduled downtime, Marvis categorizes this issue as a “non-compliant” action.
This categorization indicates that some APs are not adhering to the intended firmware version policy, which could potentially affect network performance or security. The non-compliant Marvis Action provides administrators with the necessary information to identify and rectify the issue, ensuring all APs are updated as required.
