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.

InJuniper Mist AI for Wired, configuration templates are a foundational part ofswitch onboarding and management. The primary purpose of these templates is to ensure configuration consistency across all switches that belong to a specific site or organization.

“Switch configuration templates allow administrators to define a standard configuration that is automatically applied to all switches within a site or organization, ensuring consistency and reducing configuration errors.”

Templates can contain base configuration parameters such as NTP, syslog, VLANs, port profiles, and authentication settings. When new switches are onboarded to the Mist Cloud, they automatically inherit the template’s configuration, ensuring uniform behavior across the network fabric.

Option Ais incorrect — templates do not directly impact hardware performance.

Option Bis incorrect — templates are not related to upgrade times.

Option Cis incorrect — templates are used for uniformity, not for switch-specific changes.

Option Dcorrectly describes their main benefit —ensuring consistent configuration across all switches.

EVPN, when used with VXLAN, leveragesBGP MPLS/VXLAN control plane mechanisms. To prevent overlapping IP prefixes between different tenants or sites, EVPN uses aRoute Distinguisher (RD).

“In EVPN-VXLAN, the route distinguisher (RD) makes routes unique when overlapping IP prefixes or MAC addresses are advertised between multiple tenants or sites.”

Option A(designated forwarder) applies to multi-homing in EVPN, not prefix uniqueness.

Option B(Layer 2 gateway) does not prevent IP overlap; it bridges VLANs.

Option D(ESI) is used for identifying multi-homed Ethernet segments, not to differentiate overlapping subnets.

Option C(Route Distinguisher) is correct, as it uniquely identifies routes even if the IP addresses are the same across sites.
