Juniper JN0-460 Exam With Confidence Using Practice Dumps

According to the Juniper Mist Wired Assurance Configuration Guide, the foundational step for implementing Layer 2 segmentation within the Mist UI is the creation of a "Network". In the context of Mist Wired Assurance, a Network is logically synonymous with a Virtual Local Area Network (VLAN). To define a network, a user must navigate to the Networks section—located within an organization-level template, a site-level configuration, or an individual switch configuration—and click to add a new entry.

The two mandatory parameters for this step are naming the VLAN and providing the corresponding VLAN ID. The name serves as a human-readable alias (such as "Corporate_Data" or "IoT_Devices") that allows administrators to easily reference the segment across different parts of the configuration without constantly tracking numeric IDs. The VLAN ID is the specific numeric value (ranging from 1 to 4094) that will be used by the switch for 802.1Q tagging on the physical wire.

This step is a prerequisite for more advanced configurations. Once a network is created with its name and ID, it can then be selected within a Port Profile. While creating a port profile (Option C) or an access policy (Option D) are common tasks in the deployment workflow, they are dependent on the prior existence of a defined Network. For instance, a Port Profile defines how a port behaves (e.g., access vs. trunk), but it must point to a specific Network name to know which VLAN to assign to that interface. Similarly, site variables can be used to override these VLAN IDs at specific locations, but the base definition requires the initial pairing of a name and a default ID in the portal.

TheMist UI(User Interface) is Juniper’s cloud-based management platform used tomanage both wired and wireless devices, including EX, QFX, and SRX platforms.

It provides centralized visibility, configuration, analytics, and AI-driven insights for the entire enterprise network infrastructure.

WithinWired Assurance, the Mist UI enables device claiming, switch templates, configuration management, and SLE monitoring.

Wired AssurancedefinesSLEs (Service Level Expectations)to provide measurable performance indicators for wired networks. These metrics identify root causes of network degradation by monitoring switch health, connection success, and throughput performance.

“Juniper Mist Wired Assurance delivers AI-driven insights across key wired SLEs including Successful Connects, Throughput, and Switch Health, giving visibility into user experience and switch performance.”

Option A (Capacity):Incorrect — capacity is used in wireless SLEs, not wired.

Option B (Successful Connects):Correct— tracks connection success rate and anomalies.

Option C (Switch Health):Correct— monitors hardware, software, and PoE status.

Option D (Coverage):Incorrect — pertains to wireless SLEs.

Option E (Throughput):Correct— measures data transfer rate, latency, jitter, and loss.
