An administrator needs to create a WxLAN policy that allows all authenticated employees to access the internet but prevents them from accessing a specific internal server with the IP address 10.100.1.50, which hosts sensitive financial data.
Which two WxLAN policy rules, in the correct order, would accomplish this? (Choose 2.)
A. The final default rule for 'All Users' should be set to 'Deny'.
問題 #70
What is the primary purpose of the 802.11k protocol in a wireless network?
A. To provide the client with a list of neighboring APs and their channel information to speed up roaming.
B. To allow for faster data rates using channel bonding.
C. To encrypt data frames over the air.
D. To enforce quality of service (QoS) for voice and video traffic.
答案：A
問題 #71
An administrator is deploying APs in a new building and wants to ensure location services will be accurate. They have uploaded the floorplan and are now placing the APs.
Which two AP-specific parameters must be configured correctly on the floorplan for each AP?
(Choose two.)
A. The AP's height from the floor.
B. The name of the switch port the AP is connected to.
C. The AP's IP address.
D. The AP's orientation (direction).
E. The AP's MAC address.
答案：A,D
問題 #72
Exhibit:
Referring to the exhibit, which client has the weakest connection to the WLAN?
A. Client 4
B. Client 2
C. Client 1
D. Client 3
答案：C
解題說明：
InJuniper Networks Mist AI Wireless, the strength and quality of a client's wireless connection are primarily evaluated usingRSSI (Received Signal Strength Indicator)andSNR (Signal-to-Noise Ratio).
These two metrics are core inputs into multiple Wireless Assurance SLEs, including Coverage and Throughput, and are reliable indicators when determining which client has the weakest WLAN connection.
From the exhibit, the key metrics for each client are:
* Client 1: RSSI-81 dBm, SNR11 dB
* Client 2: RSSI -71 dBm, SNR 21 dB
* Client 3: RSSI -67 dBm, SNR 25 dB
* Client 4: RSSI -70 dBm, SNR 22 dB
In wireless design,lower (more negative) RSSI values indicate weaker signal strength, andlower SNR values indicate poorer signal qualitydue to higher relative noise. Among all listed clients,Client 1 clearly has the weakest connection, as it has both:
* Thelowest RSSI(-81 dBm), indicating it is farthest from the AP or experiencing significant attenuation.
* Thelowest SNR(11 dB), which suggests the signal is only marginally stronger than the background noise.
Mist best practices typically consider RSSI values below -70 dBm and SNR values below ~20 dB as suboptimal for reliable performance, especially for higher modulation schemes. Client 1 falls well below these thresholds, making it the most likely to experience low data rates, retransmissions, and degraded user experience.
Mist AI would flag this client as having poor coverage and may recommend actions such as:
* Improving AP placement or density
* Adjusting RF power or channel plans
* Enforcing minimum RSSI thresholds
Therefore, based on both RSSI and SNR,Client 1has the weakest WLAN connection, makingOption Dthe correct answer.
問題 #73
An administrator needs to track all administrative changes made in the Mist dashboard for a specific site over the last week for audit purposes. This includes who created a new WLAN, who modified an RF template, and when an AP was rebooted via the UI.
Where can this information be found?
A. In the Marvis Actions dashboard.
B. In the Organization > Audit Logs page.
C. In the Site Events log on the Insights page.
D. In the list of System Changes on the main SLE dashboard.
