• A. Asymmetric Uplink
• B. Throughput
• C. Switch Health
• D. Successful Connect

Answer: A

Explanation:
Juniper Mist'sWired Assuranceincludes multipleSLE metricsthat monitor the health and performance of wired connections. One of these isAsymmetric Uplink, which measuresuplink congestion or imbalancebetween the transmit (TX) and receive (RX) rates on the switch uplink interfaces.
"The Asymmetric Uplink SLE monitors congestion and traffic imbalance on the switch's uplink ports. It identifies when the uplink bandwidth utilization or transmit/receive rates are inconsistent with expected patterns, indicating congestion or flow asymmetry." Option A (Successful Connect):Tracks client connection success rate, not uplink congestion.
Option C (Throughput):Relates to end-to-end data transfer rate, not specifically uplink congestion.
Option D (Switch Health):Measures hardware, software, and PoE health, not link congestion.
Option B (Asymmetric Uplink):Correct- this SLE directly reflectsuplink interface congestion or imbalance.

NEW QUESTION # 30
Which statement is correct about a 3-stage campus fabric IP Clos?

• A. The distribution layer is connected to the access layer.
• B. The core layer is connected to the access layer.
• C. The core layer devices are connected to each other.
• D. The distribution layer is connected to the core layer.

Answer: B

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.

Which two statements are correct about switch adoption?(Choose two.)

• A. Switch adoption uses SSH over TCP port 443.
• B. Brownfield switch adoption requires manual adoption and is used for switches that do not have a claim or activation code.
• C. Switch adoption requires Mist AP.
• D. Greenfield switch adoption requires cloud-enabled switches with a claim or activation code.

Answer: B,D

Explanation:
In Juniper Mist,Greenfield adoptionapplies to new, cloud-ready switches (such as EX4100, EX4400, and QFX series) using aclaim or activation codeto securely connect to the Mist cloud.
Brownfield adoption, however, supports switches already deployed or not factory-fresh. These are manually onboarded by configuring outbound management connectivity and adopting them through the Mist portal.
This distinction enables both new and legacy EX/QFX environments to be cloud-managed under Wired Assurance.

NEW QUESTION # 37
Which campus fabric architecture supportsLayer 3 gateways at the distribution layer?

• A. EVPN multihoming
• B. campus fabric core/distribution - edge-routed bridging (ERB)
• C. campus fabric core/distribution - centrally-routed bridging (CRB)
• D. campus fabric IP Clos

Answer: B

Explanation:
In Juniper'scampus fabric architectures, the location of theLayer 3 gateway(IRB) differentiates between CRB and ERB models:
Centrally-Routed Bridging (CRB):L3 gateways are placed at thecore layer.
Edge-Routed Bridging (ERB):L3 gateways are placed at thedistribution layer, closer to the edge.
"In the ERB model, Layer 2 gateways are deployed at the access layer, andLayer 3 gateways are deployed at the distribution layer." Option A (CRB):Incorrect - L3 is at the core, not distribution.
Option B (IP Clos):Incorrect - in 3-stage Clos, L3 is pushed to the access layer.
Option D (EVPN multihoming):Incorrect - this is about redundancy, not gateway placement.
Option C (ERB):Correct - L3 gateways sit at thedistribution layerin the ERB architecture.
