• D. Reduce security

Answer: A

NEW QUESTION # 60
Which statement about RadSec is correct?

• A. RadSec allows RADIUS authentication over UDP and TLS.
• B. RadSec allows RADIUS authentication over UDP and SSL.
• C. RadSec allows RADIUS authentication over TCP and TLS.
• D. RadSec allows RADIUS authentication over TCP and SSL.

Answer: C

Explanation:
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.

NEW QUESTION # 61
Which two statements are correct about thecampus fabric core-distribution architecture?(Choose two.)

• A. Only the core and distribution tiers are part of the EVPN-VXLAN topology.
• B. Only the core tier participates in the EVPN-VXLAN topology.
• C. The access tier is included in the EVPN-VXLAN topology.
• D. The access tier does not participate in the EVPN-VXLAN topology.

Answer: A,D

Explanation:
In acore-distribution campus fabricmodel, the EVPN-VXLAN overlay is establishedonly between the core and distribution tiers. Theaccess switches are not part of the EVPN fabric; they connect upstream to distribution but do not run VXLAN tunnels.
"In the core-distribution campus fabric, only the core and distribution layers participate in the EVPN-VXLAN topology. The access layer connects to the distribution switches and forwards traffic but does not take part in the EVPN-VXLAN fabric." Option A:Correct - EVPN-VXLAN is built between core and distribution tiers.
Option B:Incorrect - both coreand distributionparticipate, not just core.
Option C:Incorrect - access switches are excluded from EVPN-VXLAN participation.
Option D:Correct - the access layer does not participate in EVPN-VXLAN.

NEW QUESTION # 64
Which service level expectation (SLE) metric measures congestion on the uplink interface of a switch?

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

Answer: D

Explanation:
According to Juniper Mist documentation, the Throughput Service Level Expectation (SLE) is the primary metric used to represent the ability of wired users to pass traffic across the network without impedance. This SLE provides a comprehensive oversight of network performance by identifying issues that degrade the user experience, such as storm control events, interface anomalies, and specifically uplink congestion.
Within the Throughput SLE, the Congestion classifier (also referred to as Congestion Uplink) is specifically designed to monitor for buffer saturation and packet drops (TxDrops). When traffic arriving at an interface exceeds its processing or forwarding capacity, packets are queued in a buffer; if this buffer becomes full, the switch begins dropping packets. Juniper Mist utilizes a specific formula considering the ratios of TxDrops to TxPackets, Transmitted bps to Link Speed, and Received Speed to Link Speed to determine if a "Bad User Minute" has occurred due to congestion.
A critical feature of Wired Assurance is the automatic identification of uplink interfaces. Mist identifies these high-capacity ports by analyzing switch telemetry for characteristics such as having a switch or router as an LLDP neighbor, being designated as a Spanning Tree Protocol (STP) root port, or exhibiting significantly higher packet counts compared to access ports. When congestion is detected on an interface identified as an uplink, the system recognizes that this bottleneck impacts every user on that switch. By correlating these drops with the Throughput SLE, network administrators can proactively identify when a site requires more bandwidth or a different fabric architecture to handle current traffic demands, rather than simply monitoring if the link is physically "up" or "down".
