NEW QUESTION # 30
Which statement is correct about the VXLAN data plane?

• A. The data plane learns the MAC addresses of end-user devices.
• B. The data plane advertises the MAC addresses of end-user devices.
• C. The data plane learns the IP addresses of end-user devices.
• D. The data plane encapsulates the traffic.

Answer: D

Explanation:
VXLAN (Virtual Extensible LAN) uses an overlay encapsulation method to carry Layer-2 frames over an IP underlay. This functionality is part of the data plane, which is responsible for packet forwarding and encapsulation/decapsulation.
"In an EVPN-VXLAN fabric, the control plane (via BGP EVPN) learns and advertises MAC and IP information, while the data plane encapsulates and forwards traffic using VXLAN tunnels between VTEPs." Option A is incorrect: IP learning happens in the control plane, not the data plane.
Option B is incorrect: MAC advertisement is done in the control plane through EVPN route types.
Option D is incorrect: MAC learning is handled by EVPN control plane, not the VXLAN data plane.
Option C is correct: the VXLAN data plane encapsulates the traffic in UDP tunnels between VTEPs.

• D. Throughput
• E. Switch Health

Answer: B,D,E

Explanation:
Wired AssurancedefinesSLEs (Service Level Expectations)to provide measurable performance indicators for wired networks. These metrics identify root causes of network degradation by monitoring switch health, connection success, and throughput performance.
"Juniper Mist Wired Assurance delivers AI-driven insights across key wired SLEs including Successful Connects, Throughput, and Switch Health, giving visibility into user experience and switch performance." Option A (Capacity):Incorrect - capacity is used in wireless SLEs, not wired.
Option B (Successful Connects):Correct- tracks connection success rate and anomalies.
Option C (Switch Health):Correct- monitors hardware, software, and PoE status.
Option D (Coverage):Incorrect - pertains to wireless SLEs.
Option E (Throughput):Correct- measures data transfer rate, latency, jitter, and loss.

NEW QUESTION # 32
Which two statements are correct about theEVPN-VXLAN control plane?(Choose two.)

• A. The control plane encapsulates the traffic.
• B. The control plane learns the IP addresses of end-user devices.
• C. The control plane rewrites the destination MAC address of the packet.
• D. The control plane learns the MAC addresses of end-user devices.

Answer: B,D

Explanation:
In anEVPN-VXLAN fabric, thecontrol planeoperates overBGP EVPNand is responsible for distributing endpoint reachability information (MAC and IP) among VTEPs. Thedata plane, by contrast, performs encapsulation and forwarding.
"The EVPN control plane uses BGP to exchange MAC and IP address reachability information between VTEPs, enabling efficient forwarding and loop prevention without relying on flood-and-learn behavior." Option A:Incorrect - encapsulation occurs in thedata plane, not the control plane.
Option B:Correct - the control plane distributesMAC-to-VTEP mappings.
Option C:Correct - the control plane also distributesIP-to-MAC associations(Type 2 and Type 5 EVPN routes).
Option D:Incorrect - the control plane does not alter packet headers.

NEW QUESTION # 41
You are experiencing issues with your video streams. In this scenario, which SLE and classifier should you inspect to see if BUM traffic is a problem?

• A. Throughput Congestion
• B. Throughput Storm Control
• C. Successful Connect --> Authentication
• D. Throughput -> Interface Anomalies

Answer: B

Explanation:
According to Juniper Mist documentation, the Throughput Service Level Expectation (SLE) is the primary metric used to measure the ability of wired clients to pass traffic across the physical network without impedance. This SLE is critical for diagnosing issues with real-time, high-bandwidth applications such as video streams, which are highly sensitive to packet loss and latency. Within the Throughput SLE, the Storm Control classifier is specifically designed to identify "bad user minutes" caused by the suppression of Broadcast, Unknown Unicast, and Multicast (BUM) traffic.
Storm control is a mechanism that enables the switch to monitor traffic levels and drop BUM packets when a specified traffic level-known as the storm control level-is exceeded. This prevents a "traffic storm" from proliferating and degrading the overall performance of the LAN. While this is a vital security feature to prevent network meltdowns, it can inadvertently impact legitimate traffic. For instance, if multicast-based video streams or other heavy BUM traffic exceed the configured bandwidth percentage on a port, the switch will drop those packets to protect the rest of the network.
When troubleshooting video stream issues, network administrators should inspect the Storm Control classifier to see if it is triggering "bad user minutes". If the Mist dashboard indicates failures under this classifier, it signifies that the switch hardware is actively dropping packets because the BUM traffic limit has been reached. This provides immediate root-cause evidence, allowing the administrator to determine if they need to adjust the storm control thresholds within the Port Profile or investigate the source of the excessive broadcast traffic. By correlating these hardware-level events with the end-user experience, Mist AI simplifies the resolution of complex performance problems that traditional "up/down" monitoring would miss.

NEW QUESTION # 42
