질문 # 108
Which three categories of alert types are available in Juniper Mist? (Choose three.)
정답：B,C,D
설명：
Alerts represent network and device issues that are ongoing. Juniper Mist™ categorizes them as follows:
* Infrastructure Alerts-Repeated events involving servers and protocols that can potentially affect a large number of clients. For example, an event during which a Domain Name System (DNS), Dynamic Host Configuration Protocol (DHCP), or RADIUS server is unreachable can affect many clients.
Similarly, if a power supply on a switch is in alarm state, a large number of clients and a large amount of traffic could be affected.
* Marvis Alerts-Repeated events that Marvis tracks on the Marvis Actions dashboard. For example, if an access point (AP) regularly fails health checks, you'll see a Marvis alert for it.
* Security Alerts-Repeated events that could dramatically affect network security. For example, these alerts appear if a rogue AP is detected and clients start connecting to it.
* Certificate Alerts-Notification for expired, and soon-to-expire, user-added digital certificates. These include RadSec (configured at Organization > Settings > RadSec Certificates and AP RadSec certificate), SSO (configured at Organization > Settings > Single Sign-On), and PSK Portal IDP certificates (configured at Organization > Client Onboarding). Certificate alerts appear on the Alerts page and begin 30 days before the certificate's expiry date, then the notification repeats 15, 7, 3, and 1 day before expiration unless the certificate is renewed. .

질문 # 109
Marvis has notified you that you have a bad cable.
What additional information does the Marvis Actions dashboard provide to help you solve the issue?
정답：D
설명：
TheMarvis Virtual Network Assistant (VNA)in Juniper Mist AI uses real-time telemetry and AI-driven correlation to identify hardware and connectivity issues, including bad cable conditions. When a"Bad Cable" alert is raised, Marvis analyzes physical link metrics from the switch and AP-such as CRC errors, FCS drops, and link flaps-to isolate the root cause.
According to the Juniper Mist AI Operations Guide, theMarvis Actions dashboardprovides contextual insights into the issue, showing whether the fault lies in thephysical cableitself or theswitch portit is connected to. Specifically, the dashboard highlights:
* The affected device and port.
* Whether the degradation originates from theport hardwareor thecabling.
* Suggested corrective action (e.g., replace the cable or check switch hardware).
Marvis uses its AI-driven root cause analysis engine to distinguish between cable integrity problems and port failures by examining electrical signature anomalies and historical telemetry.
Options B, C, and D are incorrect because Marvis does not display cable category ratings or identify individual broken Ethernet pairs-it focuses on identifying and isolating the fault domain.
Therefore, the correct answer isA. If the port or cable is at fault.

질문 # 110
Exhibit:
Referring to the exhibit, which SLE would an administrator investigate to troubleshoot weak signal issues?
정답：A
설명：
InJuniper Mist Wireless Assurance,Service Level Expectations (SLEs)are key metrics that measure different aspects of the end-user experience. Each SLE focuses on a distinct area of network performance such asConnection,Roaming,Throughput, andCoverage.
TheCoverage SLEspecifically measures whether wireless clients are receiving adequate signal strength (RSSI) and signal quality (SNR) from access points. According to theJuniper Mist AI Operations and SLE Analytics Guide, this metric is defined as:
"The Coverage SLE quantifies the percentage of client sessions that meet the required signal strength and quality thresholds. Low coverage indicates areas with weak or inconsistent RF signal levels." When users experienceweak signal or dead zones, theCoverage SLEprovides insight into where and why these issues occur. Mist AI identifies sub-classifiers such asSignal Quality,Wi-Fi Interference, orAirtime Utilization, allowing administrators to isolate the cause of poor signal conditions.
Therefore, in the exhibit shown, an administrator would investigate theCoverage SLE (79%), as it directly relates to signal weakness or RF coverage problems.

질문 # 111
Which Juniper Mist feature tracks the location of important devices and objects within a building?
정답：D
설명：
Juniper Mist Asset Visibility is the feature that tracks and displays the real-time location of important devices and objects within a building, providing detailed visibility into asset movement and placement.
질문 # 112
Which statement is correct about the relationship between Juniper Mist organizations and sites?
정답：B
설명：
According to the official Juniper Mist documentation on the configuration hierarchy, the platform uses a three- tier model: Organization # Site # Device. At the organization level, you manage administrator accounts, subscriptions, and organization-wide settings. Then:
"An organization can include one or more sites. A site can represent a physical location or a logical subdivision of your enterprise or campus." Also, in the simpler case explanation:
"Each customer is created as a separate organization. Within that organization multiple sites can be created." Mist These statements make clear that the correct relationship is: one organization may have multiple sites under it.
The inverse - that a site might contain multiple organizations - is not supported in the documented hierarchy. Therefore option B is correct.
