質問 # 33
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. Verify that both switch ports are set toauto-negotiatespeed and duplex.
- D. Check that the connected device supports802.3 autonegotiation.
正解：C、D
解説：
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:

質問 # 34
Which statement about RadSec is correct?
- A. RadSec allows RADIUS authentication over UDP and SSL.
- B. RadSec allows RADIUS authentication over TCP and SSL.
- C. RadSec allows RADIUS authentication over UDP and TLS.
- D. RadSec allows RADIUS authentication over TCP and TLS.
正解：D
解説：
RadSec(RADIUS over TLS) enhances traditional RADIUS authentication security by encapsulating RADIUS messages withinTCP and TLSinstead of UDP.
This ensures encrypted, reliable, and authenticated transmission between network devices (such as Juniper EX switches) and RADIUS servers.
It is often used in modernMist-managed wired networksto securely integrate withAccess Assuranceor external authentication systems.

"The Switch Insights page displays real-time and historical data such as traffic per port, PoE usage, connected clients, and interface errors for every switch managed by Mist." Option A:Correct- port-level traffic and utilization metrics are visible in Switch Insights.
Option B:Incorrect - available for all Mist-managed switches (EX and supported QFX).
Option C:Incorrect - displays complete event history, not limited to five events.
Option D:Incorrect - configuration rollback is done via the configuration history section, not Switch Insights.

質問 # 41
Which of the following are features of managing switches with MistAI Wired Assurance? (Select two)
- A. Real-time gaming
- B. AI-driven insights for switch health
- C. Automatic switch configuration rollback
- D. Manual switch discovery

質問 # 42
Whichtwo statementsare correct about using theManaged optionas yourJuniper Mist Wired Assurancesolution?(Choose two.)
- A. All supported wired devices are fully managed by the Mist AI.
- B. A subscription is required.
- C. No subscription is required.
- D. All information in the Mist AI for supported wired devices is read-only.
正解：A、B
解説：
When deployingJuniper Mist Wired AssuranceinManaged mode, switches are fully integrated with Mist Cloud for configuration, monitoring, and AI-driven operations. Managed mode providescomplete cloud-based management, meaning Mist AI handles configuration, templates, telemetry, and SLE tracking.
"In Managed mode, the switch configuration is fully managed by Mist Cloud. Administrators configure switches, templates, and policies directly through the Mist dashboard. A valid Wired Assurance subscription is required for Managed mode operation." Option A:Incorrect - the "Monitor Only" mode is read-only, not Managed.
Option B:Correct- Managed mode requires aWired Assurance subscription.
Option C:Incorrect - subscriptions are mandatory for Mist-managed devices.
Option D:Correct- in Managed mode,all supported EX switches are fully managed by Mist AI, including configuration and telemetry.

質問 # 45
You must move from acampus fabric core-distribution centrally-routed bridging (CRB)network to anedge- routed bridging (ERB)network.
In this scenario, where does thegateway for the networkmove?
- A. from distribution to access
- B. from core to distribution
- C. from distribution to core
- D. from access to distribution
正解：A
解説：
In Juniper Mist campus fabric architectures, thelocation of the Layer 3 gateway (IRB interface) differentiatescentrally-routed bridging (CRB)fromedge-routed bridging (ERB):
InCRB, thegateway resides at the core layer- routing occurs centrally, and access/distribution layers perform Layer 2 bridging.
InERB, thegateway moves to the edge (distribution layer), enabling routing to occur closer to endpoints, improving performance and scalability.
"In a centrally-routed bridging (CRB) topology, Layer 3 gateways reside at the core. When transitioning to an edge-routed bridging (ERB) design, the Layer 3 gateways are moved to the distribution layer, closer to the access switches and clients." Therefore, when moving from acore-distribution CRBto anERBmodel, thegateway moves from the distribution to the access layerin campus terms (edge = access).
Option A:Incorrect - ERB gateways are not at the distribution layer only.
Option B:Incorrect - opposite direction.
Option C:Correct- the gateway movesfrom distribution to access (edge).
Option D:Incorrect - this describes CRB, not ERB.

質問 # 47
Which of the following is a key feature of VXLAN?
- A. Reduces broadcast traffic in Layer 2 networks
- B. Increases the need for traditional VLANs
- C. Limits the scalability of virtual networks
- D. Provides Layer 2 tunneling over Layer 3 networks
正解：D
質問 # 48
You have two sites connected to an EVPN network. Each site is using the172.16.1.0/24network for its own respective site.
How does EVPN prevent overlap in this scenario?
- A. It uses an Ethernet segment identifier (ESI).
- B. It uses a route distinguisher.
- C. It uses a Layer 2 gateway.
- D. It elects a designated forwarder.
正解：B
解説：
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.
