A.MACsec encryption
B.AI-driven Root Cause Analysis
C.VLAN auto-provisioning
D.DNS inspection

정답:
Explanation:
Wireless Assurance uses Marvis AI to perform root cause analysis, which dramatically improves issue detection speed and accuracy compared to manual Wi-Fi monitoring.

Question No : 3

Which dashboard allows viewing site-wide wireless health KPIs in Mist?

A.Site Performance
B.Site Map
C.SLE Overview
D.Topology

정답:
Explanation:
The SLE Overview dashboard aggregates key metrics across the wireless infrastructure, such as onboarding time, throughput, and signal quality. It helps visualize client experience at a site level.

Question No : 4

What is the purpose of assigning switch profiles in Wired Assurance?

A.To enforce IPS policies
B.To manage routing tables
C.To apply standardized port configs
D.To extend VLANs across buildings

정답:
Explanation:
Switch profiles are used to apply consistent port configurations across similar switch models or roles.
They ensure uniform behavior, which simplifies operations and provisioning.

Question No : 5

What is a key outcome of using Wireless Assurance’s AI-driven insights?

A.Creation of physical network topologies
B.Reduction in manual ticket resolution
C.Improvement in routing table distribution
D.Faster cable replacement planning

정답:
Explanation:
Wireless Assurance uses AI to detect and suggest solutions for Wi-Fi issues, reducing the manual workload on IT teams and accelerating issue resolution through automation.

Question No : 6

Which SLE category is not part of Wireless Assurance by default?

A.Coverage
B.Roaming
C.Gateway Latency
D.Throughput

정답:
Explanation:
Gateway Latency is typically not included in Wireless Assurance's default SLEs, which focus more on Wi-Fi-specific metrics like coverage, onboarding, throughput, and roaming.

Question No : 7

What information does Port Health in Wired Assurance display?

A.Firewall rule matches
B.Cable test results
C.VLAN routing paths
D.Application usage

정답:
Explanation:
Port Health includes cable diagnostics, power delivery stats, and traffic error monitoring. It does not handle firewall rules, VLAN paths, or app-layer data.

Question No : 8

What does the term "port bounce" refer to in Wired Assurance troubleshooting?

A.Port is overloaded
B.Port receives DDoS
C.Port is shut and enabled automatically
D.Port loops traffic

정답:
Explanation:
A "port bounce" is the process of administratively disabling and re-enabling a port to recover from issues like stuck sessions or failed negotiation. It’s a common troubleshooting method.

Question No : 9

Which metric is used by the Wireless Assurance throughput SLE?

A.Ping latency
B.TCP throughput test results
C.Port error count
D.Wi-Fi channel width

정답:
Explanation:
Wireless Assurance uses TCP throughput tests to measure the actual user experience on Wi-Fi. It gives a realistic performance view, unlike latency or channel width alone.

Question No : 10

Which feature of Wireless Assurance helps optimize Wi-Fi performance proactively?

A.Scheduled VLAN rotation
B.Automatic RF adjustments
C.Intent-based micro-segmentation
D.Link Aggregation Control Protocol

정답:
Explanation:
Wireless Assurance uses AI to recommend or implement proactive RF adjustments for better signal and channel quality. VLANs and LACP relate to wired switching, not RF optimization.

Question No : 11

Which Mist tool would help visualize switch-level anomalies across time?

A.Anomaly Timeline
B.Port Inspector
C.Marvis Dashboard
D.Device Inventory

정답:
Explanation:
The Anomaly Timeline provides a historical view of abnormalities on switches, helping administrators track trends and identify recurring issues. Port Inspector offers real-time snapshots instead.

Question No : 12

What is the function of Wireless Assurance onboarding SLE?

A.To measure software update time
B.To assess client authentication time
C.To monitor RF interference
D.To report PoE consumption

정답:
Explanation:
The onboarding SLE tracks how quickly and successfully clients connect to the network, including DNS, DHCP, and authentication stages. It ensures a smooth initial experience for users.

Question No : 13

Which two data types are collected by Wired Assurance? (Choose two.)

A.Port utilization metrics
B.Wireless signal strength
C.MAC address authentication
D.Switch health telemetry

정답:
Explanation:
Wired Assurance gathers switch health data, such as temperature, CPU, memory, and port-level metrics like utilization and errors. Wireless signal strength is managed under Wireless Assurance.

Question No : 14

Which Mist solution provides port-level insights for connected wired clients?

A.Access Assurance
B.Wired Assurance
C.Secure Edge
D.Port Authentication Manager

정답:
Explanation:
Wired Assurance delivers real-time port-level analytics for wired clients, allowing visibility into traffic, errors, and power usage. It is not involved in access control or security.

Question No : 15

Which capability helps Wireless Assurance reduce Mean Time to Repair (MTTR)?

A.Radio Resource Management
B.Virtual AP tunneling
C.Dynamic RF planning
D.Root cause identification

정답:
Explanation:
Wireless Assurance uses machine learning to analyze failures and identify the root cause rapidly. This directly contributes to reducing MTTR for Wi-Fi-related issues.
