JN0-253 Exam Dumps : Mist AI - Associate (JNCIA-MistAI)

The three valid methods for requesting authentication with the Juniper Mist API are:

Use an HTTPS login with a user name and password: The Mist API accepts HTTPS requests where credentials are provided directly for session/token generation and user administration.

Use OAuth2 linked to an OAuth provider: "Juniper Mist APIs offer authentication via OAuth2 with various OAuth-compatible identity providers, such as Okta, for secure and federated access."

Enable basic authentication with a token: Mist APIs accept programmatic requests using tokens (API tokens or bearer tokens) for automation, scripting, and integration—each token mapping to specific scopes and user permissions.

Enabling MFA with Okta Verify enhances user portal security but is not an API authentication mechanism. RADIUS certificates are used for infrastructure 802.1X authentication, not for API access.

The WAN Edge Health SLE in Juniper Mist monitors critical operational metrics for WAN edge devices. According to Juniper’s documentation: “Juniper Mist analyzes various factors that affect WAN edge health and assigns a score… Classifiers include Memory—triggered when WAN edge memory utilization is above 80 percent and CPU—triggered when control or data plane CPU utilization is above 90 percent.” These components directly impact the device’s ability to process traffic. Monitoring these parameters enables rapid detection of system resource constraints, which are essential for ensuring optimal WAN performance. While ISP reachability is a separate SLE (usually part of WAN Link SLEs), application response times are tracked in Application SLEs.

In Juniper Mist, allhardware device onboarding and claiming operations—including access points (APs), switches, and gateways—are performed under theInventorysection of the Mist Cloud Portal.

According to the Juniper Mist Cloud documentation, theInventorypage serves as the centralized location for device lifecycle management. It allows administrators to:

Claim new devicesusing their serial numbers or activation codes.

Batch import multiple APsvia manual entry or CSV upload.

Assign claimed devicesto specific sites for configuration and management.

Monitor device claim status, model type, firmware version, and cloud connectivity state.

The documentation specifies:

“To onboard or claim multiple access points in the Mist Cloud, navigate toOrganization → Inventory, then clickClaim Devices. Enter or paste serial numbers of the APs you want to add, and assign them to the appropriate site.”

Other options are incorrect because:

Subscriptionsmanages licensing and service entitlements.

Devicesshows active device status per site but does not handle claiming.

Client Onboardingis used for guest access or authentication workflows, not hardware management.

Therefore, the correct answer isInventory (C).
