NEW QUESTION # 137
An administrator is designing a highly available network for a corporate headquarters with two Mist Edge appliances located in the same Layer 2 segment. The goal is to ensure that AP tunnels are load- balanced across both appliances and that if one appliance fails, the other can handle the full load. Which two configuration steps are essential to achieve this design? (Choose 2.)
Answer: C,E
NEW QUESTION # 138
Exhibit:
Referring to the exhibit, which client has the weakest connection to the WLAN?
Answer: A
Explanation:
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.
NEW QUESTION # 139
Which two terms correctly describe transmissions over Wi-Fi? (Choose two.)
Answer: A,B
Explanation:
Transmissions over Wi-Fi are shared medium and half-duplex.
According to the IEEE 802.11 - Wikipedia document2, two terms that correctly describe transmissions over Wi-Fi are:
* Shared medium, which means that multiple devices use the same wireless channel and have to compete for access and avoid collisions.
* Half-duplex, which means that devices can either transmit or receive data at a time, but not both simultaneously.

NEW QUESTION # 140
You are asked to troubleshoot issues at a customer's site utilizing the Service-Level Expectations (SLEs).
According to Juniper Networks, in which order should you start troubleshooting the SLEs in this scenario?
Answer: C
Explanation:
InJuniper Networks Mist AI Wireless, Juniper prescribes atop-down, structured troubleshooting methodologywhen using Service-Level Expectations (SLEs). This approach ensures that engineers identify systemic issues before drilling into individual client problems, preventing misdiagnosis and wasted effort.
The correct troubleshooting order is:
Organization # Site # SLE # Client
* Organization of interestTroubleshooting always begins at the organization level. This provides a global view of overall health, license status, widespread outages, and configuration changes that may impact multiple sites. Organization-level visibility helps determine whether the issue is localized or systemic.
* Site of interestAfter confirming the organization is healthy, the next step is narrowing the scope to the affected site. Site-level views expose infrastructure issues such as WAN problems, DHCP outages, AP connectivity issues, or RF-wide anomalies that affect many users simultaneously.
* SLE of interestOnce scoped to the site, administrators identify the specific degraded SLE (for example, Time to Connect, Coverage, Capacity, or Throughput). Each SLE includes classifiers that pinpoint the likely root cause, such as DHCP, DNS, authentication, or RF interference.
* Client of interestOnly after isolating the failing SLE should troubleshooting move to the individual client level. Client views provide detailed timelines, event history, and packet-level insights to confirm whether the issue is isolated or a symptom of a broader problem.
The other answer choices are incorrect because they start with either the SLE or client, which risks overlooking organization-wide or site-wide conditions. Juniper's recommended workflow ensures efficient, accurate fault isolation and aligns with how Mist AI correlates telemetry and events.
Therefore, the correct answer isA. Organization of interest, site of interest, SLE of interest, client of interest.
