NEW QUESTION # 70
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: B
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 # 71
Which Wireless Assurance SLE provides information on whether a user is able to associate to the WLAN?
Answer: B
NEW QUESTION # 72
An access point discovers switch information using which protocol?
Answer: D
Explanation:
InJuniper Networks Mist AI Wireless, access points discover upstream switch and port information using Link Layer Discovery Protocol (LLDP). LLDP is an IEEE-standard, vendor-neutral Layer 2 discovery protocol designed specifically to allow network devices to advertise and learn information about directly connected neighbors.
When a Juniper Mist AP connects to a wired switch, it uses LLDP to exchange information such as:
* Switch hostname and chassis ID
* Switch port identifier
* VLAN details
* Power over Ethernet (PoE) capabilities and power allocation
This information is critical for Mist operations and visibility. It enables the Mist cloud to accurately display AP-to-switch mappings, identify theexact switch portan AP is connected to, validate PoE delivery, and assist with troubleshooting wired-side issues that impact wireless performance. LLDP data is also leveraged by Mist AI and Marvis to correlate wired and wireless events, improving root-cause analysis.
The other options are incorrect for the following reasons:
* CDP (Cisco Discovery Protocol)is a Cisco-proprietary protocol and is not used by Juniper Mist APs for switch discovery.
* ARP (Address Resolution Protocol)resolves IP addresses to MAC addresses and does not provide device or port identity information.
* SNMPis a management and monitoring protocol used by controllers or management systems, not by APs for neighbor discovery.
Because LLDP is standards-based, lightweight, and designed for neighbor discovery, it is the correct and supported protocol used by Juniper Mist APs to learn switch information.
Therefore, the correct answer isD. LLDP.
NEW QUESTION # 73
Click the Exhibit button. You are asked to troubleshoot an authorization issue at a customer's site. You start to troubleshoot the client that is responsible for the most "bad events" at this site.
Referring to the exhibit, what is the name of the client that you would begin troubleshooting?
Answer: B
Explanation:
The client with the highest overall impact is responsible for the largest share of bad events at the site. Troubleshooting should begin with that client because resolving its issue would have the greatest effect on improving the authorization SLE.
NEW QUESTION # 74
Which statement best describes Mist's approach to RRM (Radio Resource Management)?
Answer: A
Explanation:
Mist's cloud-based AI-driven RRM continuously monitors RF conditions and dynamically adjusts channel and power settings in near real-time, rather than relying on periodic or manual reconfiguration.
