TheInstallerrole in theJuniper Mist Cloudis atemporary, limited-access account typeused for onboarding network devices—typicallyAccess Points (APs)—during initial deployment. It provides restricted visibility and configuration rights necessary for installation tasks but expires automatically after a definedgrace periodto maintain network security and access control.

According to theJuniper Mist Cloud Administration and User Management Guide:

“The Installer role provides temporary access to add, claim, and verify devices at a site. This access expires automatically after the predefined installation grace period.”

This role is ideal for field engineers or contractors performing device installations without granting them long-term administrative privileges. The grace period is typicallyseven days, after which the Installer account loses access to the organization automatically.

Other roles differ as follows:

Super Observer:Read-only access across the entire organization.

Observer:Read-only access limited to assigned sites.

Helpdesk:Focused on monitoring and basic troubleshooting tasks, not installation.

Therefore, the correct answer isB. Installer.

TheJuniper Mist Cloud portalprovides a user-friendly interface that supports multiple languages to enhance accessibility for global users. The language preference determines the display language for menus, dashboards, and configuration pages across the Mist UI.

According to theJuniper Mist Cloud Administration Guide, the portal’s language can be modified as follows:

“Users can change the display language of the Mist portal using the Change Language drop-down list located in the upper-right corner of the interface.”

This option allows users to immediately switch the UI language without affecting other users in the organization or requiring administrative permissions. The change is applied per user profile and is stored for future sessions.

Other listed options are invalid:

A:The Alerts page does not include language settings.

B:The My Account page shows personal info but not display language options.

C:Organization templates are unrelated to UI preferences.

Therefore, the correct answer isD. Use the Change Language drop-down list of the Juniper Mist portal.

In theJuniper Mist Cloud licensing model, subscriptions represent service entitlements that enable specific features such asWireless Assurance,Wired Assurance,WAN Assurance,Marvis Virtual Network Assistant, andPremium Analytics. These subscriptions are managed at theorganization leveland are not permanently tied to individual hardware units.

According to theJuniper Mist Licensing and Subscription Management Guide, subscriptions are:

“Cloud-based entitlements associated with an organization, not bound to specific device serial numbers. Devices draw from the subscription pool dynamically.”

This design allows flexibility and simplifies device replacement or scaling:

When a new device (for example, an access point or switch) is added to the organization, thesubscription is automatically assignedto it from the available pool.

If a device isremoved or fails, the subscription is automaticallyreleased and reassignedto a replacement unit—no manual transfer is required.

Therefore:

Ais correct because subscriptions are not linked to a single device’s serial number.

Dis correct because subscriptions automatically reapply when replacement devices are onboarded.

OptionsBandCare incorrect because Juniper Mist subscriptions are organization-based, not hardware-bound, and require no manual reassignment after device failure or replacement.
