NEW QUESTION # 123
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: D,E
NEW QUESTION # 124
A client has a poor Wi-Fi experience when moving around in an office. In this scenario, which Marvis Query Language clause would help troubleshoot the problem?
Answer: C
Explanation:
In the Juniper Mist AI ecosystem, troubleshooting the mobility experience of a user requires analyzing the transitions between Access Points (APs). When a client reports a "poor experience when moving," it almost always points to a breakdown in the roaming process, such as sticky clients (devices that refuse to move to a closer AP), slow handoffs, or authentication failures during a roam. The Marvis Query Language (MQL) provides a conversational and structured way to extract this specific data using the ROAMINGOF clause.
The ROAMINGOF clause is designed to filter the massive amount of telemetry collected by Mist and focus specifically on the events surrounding a client's transition from one radio to another. When you execute a query like "Roaming of [Client Name]," Marvis returns a detailed visualization of the client's journey. This includes the signal strength (RSSI) at the time of the roam, the duration of the handoff, and whether the roam was "successful," "slow," or "failed".
By using this clause, an administrator can quickly identify if the "poor experience" is caused by poor overlap (where RSSI drops too low before a new AP is found) or if the client is holding onto a distant AP (sticky client behavior). Other clauses like STATUSOF (A) are used for general health checks, UTILIZATIONOF (C) tracks radio or site traffic levels, and RANK (D) is typically used to identify the best or worst performing entities (like "Rank APs by interference"). Only ROAMINGOF provides the temporal and spatial correlation needed to fix issues specifically related to user movement within the office environment.
NEW QUESTION # 125
From the Mist Marvis Minis dashboard you notice a failed test. When viewing the current test result, all tests passed except for the Application test. What would be a reason for the failed test?
Answer: B
Explanation:
In Marvis Minis, if all tests (DHCP, ARP, DNS) succeed but the Application test fails, it indicates that connectivity to the application itself is blocked. A common cause is a firewall rule preventing access, while basic network services remain functional.
NEW QUESTION # 126
By default, Marvis Minis runs automatic tests at which interval?
Answer: D
Explanation:
Marvis Minis, the digital experience twin from Juniper Mist, validates network health by performing synthetic tests without requiring real clients to be present. These automated tests simulate client interactions-such as DHCP, DNS, and Authentication-and occur by default at an interval of every hour (60 minutes) to proactively detect issues.
NEW QUESTION # 127
You are troubleshooting a client that has had intermittent connectivity problems. Using Marvis to troubleshoot, you see that AP uptime is negatively affecting the client. When inspecting Marvis' troubleshooting response, which category should you select to see when the AP went offline?
Answer: C
Explanation:
According to the Marvis - Mist document, Correlation is a category in Marvis' troubleshooting response that shows when the AP went offline. Correlation shows the correlation between events and SLEs for a given client or AP.
