NEW QUESTION # 33
You are asked to identify whether your wired network is experiencing issues withjitter.
Which Juniper MistWired Assurance service-level expectation (SLE)metric provides these details?

• A. Switch Health
• B. Successful Connect
• C. Capacity
• D. Throughput

Answer: D

Explanation:
InJuniper Mist Wired Assurance, SLEs (Service Level Expectations) measure key performance indicators for wired network quality.Throughput SLEmonitorsdata transfer quality, includinglatency, jitter, and packet loss, which directly impact real-time applications such as voice or video.
"The Throughput SLE provides visibility into end-to-end network performance by tracking latency, jitter, and packet loss, helping identify congestion or quality issues across wired connections." Option A (Throughput):Correct- this SLE includes jitter measurement.
Option B (Successful Connect):Tracks client connection success rate, not jitter.
Option C (Capacity):Monitors link utilization and load, not jitter.
Option D (Switch Health):Monitors device hardware and software health, not traffic performance.

NEW QUESTION # 37
In a Juniper Mistcampus fabric deploymentusingEVPN-VXLAN, which component performs the VXLAN encapsulation and de-encapsulation functions?

• A. VTEP
• B. VLAN
• C. EVPN route reflector
• D. GBP tag

Answer: A

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
InEVPN-VXLANarchitectures, theVXLAN 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 aVTEPthat 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." References:

NEW QUESTION # 40
A company is planning to deploy aJuniper Mist campus fabricand wants to implementgroup-based policy (GBP)for microsegmentation.
Which statement is correct in this scenario?

• A. GBP configuration should be repeated on every individual switch in the fabric.
• B. GBP requires access switches to be EX4100 or EX4400 switches.
• C. GBP configuration must be applied to each individual switch in the fabric using the CLI.
• D. GBP can be implemented on any Juniper Networks switch that supports EVPN-VXLAN.

Answer: B

Explanation:
Group-Based Policy (GBP)is a Juniper EVPN-VXLAN feature that enablesmicrosegmentationwithout requiring multiple VRFs or VLANs. It is implemented within Juniper Mist'sWired Assurance and Campus Fabricframeworks.
"GBP provides scalable, identity-based segmentation for campus fabrics and is supported on EX4100 and EX4400 Series switches operating in EVPN-VXLAN mode under Mist management." The feature requires hardware and software support forEVPN-VXLAN and GBP tagging, which is currently available on specific EX models managed by Mist Cloud.
Option A:Correct- GBP requires compatible access switches, specifically EX4100 and EX4400 models.
Option B:Incorrect - GBP is centrally managed through Mist Cloud, not configured per switch.
Option C:Incorrect - GBP is provisioned via Mist Cloud, not the CLI.
Option D:Incorrect - GBP is not supported onallEVPN-capable switches; only on defined platforms (EX4100
/EX4400).

NEW QUESTION # 43
Referring to the exhibit, what is the purpose of theSavebutton in the upper-right corner of the Mist dashboard?

• A. It applies the port configuration changes to the switch.
• B. It resets the port configuration to its default settings.
• C. It previews the impact of the port configuration changes before applying them.
• D. It generates a backup of the current port configuration.

Answer: A

Explanation:
In theJuniper Mist AI for Wired dashboard, administrators can select one or more switch ports (as shown in the exhibit, e.g., port ge-0/0/25 on an EX4100-48MP). Once configuration changes are made - such as VLAN assignment, port profiles, PoE settings, or administrative state - theSave buttonmust be clicked to confirm and apply those changes to the device.
"When making configuration changes in the Mist switch interface, the Save button must be used to confirm the modifications. Clicking Save applies the selected port settings to the switch through Mist Cloud." Option Ais incorrect: saving does not create a backup. Backups and snapshots are handled through Mist's configuration archive, not via the Save button.
Option Bis incorrect: Save does not reset configuration; instead, it commits changes.
Option Cis incorrect: there is no preview function tied to Save.
Option Dis correct: the Save button is explicitly forapplying configuration changesto the selected switch or port(s).

NEW QUESTION # 44
You are asked to add a newVLANin your network. You need to reference the same VLAN in multiple places in the configuration of switches and APs in your site.
Which Mist configuration tool will enable you to accomplish this task?

• A. switch template
• B. site variables
• C. site switch configuration
• D. WLAN template

Answer: B

Explanation:
InMist Cloud,site variablesare used to store and reference common configuration values (such as VLAN IDs, subnet addresses, or gateway IPs) that are reused across multiple devices and templates within a site.
"Site variables allow administrators to define reusable configuration parameters that can be referenced in multiple templates or device configurations, ensuring consistency and reducing manual errors." Option A:Incorrect - applies configuration directly, not reusable references.
Option B:Correct- site variables enable you to reference the same VLAN or value in multiple configurations (switches, WLANs, etc.).
Option C:Incorrect - WLAN templates are for wireless SSID configuration.
Option D:Incorrect - switch templates define static configuration but don't store shared variables.

NEW QUESTION # 46
You receive aMarvis Actionthat reports"Port negotiation mismatch detected on EX3400-48P." In this scenario, which two steps should you take to resolve the issue? (Choose two.)

• A. Replace the switch uplink SFP module.
• B. Force the connected device port tohalf-duplexmode.
• C. Check that the connected device supports802.3 autonegotiation.
• D. Verify that both switch ports are set toauto-negotiatespeed and duplex.

Answer: C,D

Explanation:
Aport negotiation mismatchoccurs when the local and remote interfaces fail to agree on common speed or duplex settings.
Marvis Wired Assurance automatically detects this by analyzing telemetry from the switch's physical interfaces.
You can resolve this by ensuringauto-negotiationis enabled on both ends (A) and verifying the peer device supports the802.3 autonegotiation standard(D).
Manually forcing half-duplex or replacing hardware is unnecessary unless the hardware is faulty.
"Marvis Wired Actions correlate interface negotiation errors with LLDP neighbor data to pinpoint mismatched configurations, helping administrators quickly verify speed/duplex compatibility and 802.3 autonegotiation support." References:

NEW QUESTION # 47
What are two unique advantages about configuration automation in Wired Assurance? (Choose two.)

• A. client SLEs
• B. programmable workflows
• C. switch insights
• D. 100% open APIs

Answer: B,D

Explanation:
Wired Assurance in Mist Cloud provides automated configuration for Juniper EX Series switches. The automation is built on open APIs and supports programmable workflows, which allow seamless integration with external systems and reduce manual configuration errors.
"Wired Assurance leverages 100% open APIs, enabling integration with third-party automation and orchestration tools. Combined with programmable workflows, this provides a consistent and scalable automation framework for switch deployment and management." Option A (100% open APIs): Correct - APIs enable automation and external integration.
Option C (programmable workflows): Correct - workflows automate repetitive tasks and provisioning.
Option B (client SLEs): Incorrect - this is part of user experience monitoring, not automation.
Option D (switch insights): Incorrect - this relates to telemetry and visibility, not automation.
