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

答えを確認する

正解:
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

答えを確認する

正解:
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

答えを確認する

正解:
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

答えを確認する

正解:
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

答えを確認する

正解:
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

答えを確認する

正解:
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.
