Which two steps must be performed when configuring Dynamic Port Configuration (DPC) in the Juniper Mist dashboard? (Choose two.)
Answer : A, C
Dynamic Port Configuration (DPC) automates port role assignment based on connected device type and identity.
To enable it in Mist:
Select the Configuration Profile that defines what configuration will apply to matched devices.
Assign specific switch ports for DPC activation.
This simplifies provisioning by applying templates dynamically as clients connect.
In a Juniper Mist campus fabric deployment using EVPN-VXLAN, which component performs the VXLAN encapsulation and de-encapsulation functions?
Answer : B
Comprehensive and Detailed Explanation From Exact Extract:
In EVPN-VXLAN architectures, the VXLAN Tunnel Endpoint (VTEP) is the logical interface responsible for encapsulating and de-encapsulating Layer 2 Ethernet frames into VXLAN packets.
Each participating switch --- typically the access or distribution node --- hosts a VTEP that maps local VLANs to VXLAN Network Identifiers (VNIs).
When a packet leaves a local VLAN, the VTEP encapsulates it in a VXLAN header and routes it through the underlay IP fabric.
When received at the destination VTEP, the frame is de-encapsulated and delivered to the appropriate local VLAN.
''VTEPs in an EVPN-VXLAN campus fabric perform MAC-to-VNI mapping and encapsulate/decapsulate traffic between virtualized network segments, allowing seamless Layer 2 and Layer 3 connectivity across an IP underlay.''

What are two limitations of using LLDP for identifying wired clients? (Choose two.)
Answer : A, C
Link Layer Discovery Protocol (LLDP) is a Layer 2 discovery protocol that allows network devices to advertise identity and capabilities to directly connected neighbors. While LLDP is useful for basic topology discovery, it has two key limitations in Wired Assurance client identification:
''LLDP operates at Layer 2 between directly connected devices and must be explicitly enabled on all participating network elements to provide neighbor information. It cannot discover devices beyond the first physical hop.''
Option A: Correct --- LLDP must be configured and enabled on each network device to function.
Option B: Incorrect --- LLDP itself is scalable but limited to direct adjacency.
Option C: Correct --- LLDP only works between directly connected devices.
Option D: Incorrect --- not all clients support LLDP; however, the question asks for limitations of using LLDP, not lack of support.

What is the primary benefit of using switch configuration templates?
Answer : D
In Juniper Mist AI for Wired, configuration templates are a foundational part of switch 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 A is incorrect --- templates do not directly impact hardware performance.
Option B is incorrect --- templates are not related to upgrade times.
Option C is incorrect --- templates are used for uniformity, not for switch-specific changes.
Option D correctly describes their main benefit --- ensuring consistent configuration across all switches.

A customer has purchased five new switches and assigned them to a site.
In the configuration hierarchy, how should a user configure the name or role of each switch?
Answer : C
In Juniper Mist Cloud, configuration hierarchy includes organization-level templates, site-level configurations, and individual switch configuration. Site and organization levels provide shared settings, while per-device details such as hostname or role are set individually.
''Device-specific attributes such as hostname, role, or management IP are configured under the individual switch configuration menu. Templates and site configurations apply globally, while individual configurations override device-level parameters.''
Option A: Incorrect --- site configuration applies to all switches at a site, not unique details.
Option B: Incorrect --- CLI configuration is not used when switches are managed by Mist Cloud.
Option C: Correct --- each switch's name and role are configured individually under Switches Switch Configuration.
Option D: Incorrect --- organization templates define global settings, not per-switch names.
