Juniper JN0-460 Exam With Confidence Using Practice Dumps

Abrownfield adoptionin Mist AI refers to onboarding existing Juniper switches (with existing configurations) into the Mist Cloud for management and monitoring. For the switch to connect successfully, it must be able to reach Mist Cloud services usingDNSandInternet connectivity.

“To onboard existing (brownfield) switches into Mist Cloud, the device must have outbound Internet connectivity and DNS resolution to discover Mist Cloud service endpoints.”

Option A:Correct— DNS is required for the switch to resolve Mist Cloud URLs.

Option B:Correct— Internet access is required for registration and telemetry exchange.

Option C:Incorrect — templates can be applied later but are not required for adoption.

Option D:Incorrect — Mist uses TCP ports 2200 or 443, not UDP 1280.

Juniper Mist AI for Wired uses group-based policy (GBP) to enforce segmentation within a single VRF, without requiring separate VRFs per user group. GBP tags classify endpoints logically (e.g., employees, guests, IoT devices) and enforce security rules across the EVPN-VXLAN fabric.

“Group-Based Policy (GBP) provides scalable segmentation by assigning tags to endpoints based on attributes such as user type, role, or device type. These GBP tags are then used in policies to control communication between groups.”

Option A is inefficient: assigning unique tags per endpoint is not scalable.

Option C is incorrect: GBP is identity-based segmentation, not location-based.

Option D is incorrect: assigning a single tag defeats the purpose of segmentation.

Option B is correct: the best practice is to assign GBP tags based on endpoint type (e.g., servers, staff, IoT, guests), which then drives policy enforcement.

Juniper Mist AI collectstelemetry for Service Level Expectations (SLEs)across wired and wireless devices. This telemetry includes metrics such as time-to-connect, throughput, coverage, and switch performance.

“Service Level Expectation (SLE) data is collected from every device and stored for up toone monthin the Mist Cloud. This allows administrators to analyze historical performance trends and troubleshoot issues based on real-time and historical data.”

Option B (2 months):Incorrect — data is not retained this long.

Option C (7 days):Incorrect — telemetry retention is longer.

Option D (24 hours):Incorrect — too short for Mist SLE analytics.

Option A (1 month):Correct — Mist Cloud retains SLE telemetry for30 days (1 month).
