NEW QUESTION # 48
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).

Answer: C
Explanation:
In Mist,sitesrepresent the physical or logical grouping of devices within an organization.
You create and manage a site configuration under theLocationhierarchy in the Mist UI.
Each site inherits organization-level settings but can override or customize specific configurations such as VLANs, templates, or switch settings.

- D. Physical security systems.
Answer: B
NEW QUESTION # 51
Which statement is correct about a 3-stage campus fabric IP Clos?
- A. The distribution layer is connected to the core layer.
- B. The core layer devices are connected to each other.
- C. The distribution layer is connected to the access layer.
- D. The core layer is connected to the access layer.
Answer: D
Explanation:
Juniper's officialCampus Fabric IP Clos designfor Mist Wired Assurance defines that the3-stage IP Clostopology eliminates the traditionaldistribution layerentirely. This architecture is intended for smaller campus environments that do not need an intermediate distribution layer between the access and core.
"Juniper's Wired Assurance supports 3-Stage and 5-Stage IP Clos deployments. The 3-Stage IP Clos is targeted towards deployments that do not require a Distribution Layer and have smaller scale requirements." Because the distribution layer is not present, the only hierarchical connection in a 3-stage campus fabric is between thecore and access layers. Traffic is routed directly at the access layer, and each access switch acts as a Layer-3 gateway (IRB) for its VLANs.
"In a campus fabric IP Clos architecture, Mist provisions Layer-3 (L3) integrated routing and bridging (IRB) interfaces on the access layer. All the access switches are configured with the same IP address for each L3 subnet." Additionally, the Juniper documentation explains that point-to-point links are configuredbetween layers, and in the case of the 3-stage design (with no distribution), this means between thecore and accessdevices:
"The point-to-point links between each layer utilize /31 addressing to conserve addresses." Therefore, the correct statement isC: The core layer is connected to the access layer.
OptionsAandBincorrectly mention a distribution layer that does not exist in this topology.
OptionDis incorrect because core (spine) devices in a Clos fabric are not interconnected with each other.

NEW QUESTION # 52
WhichAPIis used within theJuniper Mist solution?
- A. REST
- B. SOAP
- C. JSON
- D. RPC
Answer: A
Explanation:
Juniper Mist Cloud uses anopen RESTful API frameworkfor integration, automation, and programmability across all Mist services, includingWired Assurance,Marvis, andAI-driven automation.
"All Mist Cloud services are built on a 100% open REST API framework, allowing customers to automate configuration, monitoring, and troubleshooting through standard REST calls." The REST API exchanges data inJSONformat, but the API type itself isREST, not JSON.
Option A (REST):Correct- Mist services expose 100% REST-based APIs.
Option B (SOAP):Incorrect - SOAP is an older XML-based protocol not used in Mist.
Option C (JSON):Incorrect - JSON is thedata format, not the API type.
Option D (RPC):Incorrect - not used in the Mist Cloud architecture.

NEW QUESTION # 53
VTEP functions include: (Select two)

- D. Encrypting VXLAN traffic
Answer: A,B
NEW QUESTION # 54
What information doesMistuse to determine if the port is classified as anuplink?(Choose two.)
- A. if TX and RX are higher than the rest of the ports
- B. if the port has a description configured
- C. if the port is an STP root port
- D. if the port has an MTU greater than 1500 configured
Answer: A,C
Explanation:
Juniper Mist automatically classifies ports to simplify visibility and automation withinWired Assurance. The Mist cloud analyzesport telemetryandlink behaviorto determine port roles, including uplinks.
"Mist uses machine learning and switch telemetry to automatically detect uplinks by analyzing traffic behavior and topology information. Uplink ports typically exhibit higher TX/RX utilization and are identified as spanning-tree root or forwarding ports connecting upstream devices." Option A:Correct - Mist examines traffic statistics. Ports with significantly higher TX/RX utilization relative to others are likely uplinks.
Option B:Incorrect - MTU size is not a classification criterion.
Option C:Correct - Mist usesSTP information(root or designated port status) to identify uplinks.
Option D:Incorrect - port description fields are for administrative purposes only and are not used by Mist analytics.

NEW QUESTION # 55
When viewing an individual switch managed in Mist, the Utilities drop-down includes which two testing tools? (Choose two.)
- A. Upgrade Firmware
- B. Replace Switch
- C. Perform Cable Test
- D. Bounce Ports
Answer: A,B
NEW QUESTION # 56
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. Check that the connected device supports802.3 autonegotiation.
- B. Replace the switch uplink SFP module.
- C. Verify that both switch ports are set toauto-negotiatespeed and duplex.
- D. Force the connected device port tohalf-duplexmode.
Answer: A,C
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:
