List of questions
Question 11

Which two statements are true about packet captures on an AP? (Choose two.)
Mist APs have the capability to capture both wireless and wired packets. This feature allows for comprehensive network troubleshooting by providing visibility into both types of traffic.
When performing packet captures on Mist APs, the APs remain in service. This means they continue to operate and serve clients while the capture is ongoing, ensuring minimal disruption to network operations.
This functionality is critical for maintaining network availability and performance while conducting detailed packet analysis.
Reference: Juniper Networks documentation on Mist AI AP packet capture features.
Question 12

Which statement describes Marvis Actions?
Marvis Actions is a component of the Mist AI platform that provides a dashboard highlighting actionable items. This dashboard is designed to offer insights and recommendations based on the analysis performed by Marvis AI.
The focus of Marvis Actions is to present users with clear, actionable steps that can improve network performance, resolve issues, and enhance the overall user experience.
By consolidating relevant information and suggested actions, Marvis Actions helps network administrators efficiently address network challenges and optimize operations.
Reference: Juniper Networks documentation on Marvis Actions and its role within the Mist AI ecosystem.
Question 13

...want to troubleshoot a wireless client that is no longer connected to a Mist AP.
Which area within the Mist GUI would you use?
To troubleshoot a wireless client that is no longer connected to a Mist AP, you would navigate to the 'Clients' section within the Mist GUI and select 'WIFI Clients.'
This area provides detailed information about all wireless clients that have connected to the Mist APs, including their connection history, performance metrics, and any issues encountered.
By examining the data available in the WIFI Clients section, network administrators can identify the root cause of connectivity problems and take appropriate actions to resolve them.
Reference: Juniper Networks documentation on Mist GUI and client troubleshooting procedures.
Question 14

Which step must you take when configuring rogue AP detection?
Rogue AP Detection:
Rogue AP detection is crucial for maintaining network security by identifying unauthorized access points.
Configuration Step:
Enable Rogue AP Detection:
The first and necessary step in configuring rogue AP detection is enabling the feature in the Mist system.
Other Steps:
Setting proximity zones, disabling honeypot detection, and setting the RRM interval are additional configurations but not the initial or mandatory step.
Conclusion:
The correct answer is A.

Question 15

Which two Wi-Fi related SLEs are visible in the Mist UI? (Choose two.)
Wi-Fi Related SLEs in Mist UI:
SLEs (Service Level Expectations) help monitor and ensure Wi-Fi network performance.
Visible SLEs:
Capacity:
B: Capacity SLE monitors the network's ability to handle the number of connected clients and their bandwidth requirements.
Throughput:
D: Throughput SLE measures the data transfer rates, ensuring that the network meets the expected performance levels.
Other Options:
Switch Health: Relates to wired network performance, not Wi-Fi.
Application Health: Generally focuses on application performance, not specifically Wi-Fi.
Conclusion:
The correct answers are B and D.
Mist Documentation on Wi-Fi SLEs: Mist Documentation
Question 16

Which statement is correct when a subscription expires?
When a Mist subscription expires, the devices associated with that subscription continue to operate normally, ensuring there is no immediate disruption to network operations.
However, management capabilities through the Mist management GUI are restricted. This means that while the devices remain functional, you cannot make configuration changes, monitor, or manage them using the Mist management interface until the subscription is renewed.
This restriction emphasizes the importance of maintaining active subscriptions for full access to Mist's management features.
Reference: Juniper Networks documentation on Mist subscription policies and management.
Question 17

Which device detects a Layer 1 bad cable action within Marvis Actions?
The Mist Edge device is responsible for detecting Layer 1 issues, such as bad cable actions, within the Marvis Actions framework.
Mist Edge integrates with Marvis AI to provide detailed insights into network health, including physical layer issues like faulty cables, which can impact network performance.
By identifying and alerting administrators to these problems, Mist Edge helps maintain the integrity and reliability of the network infrastructure.
Reference: Juniper Networks documentation on Mist Edge and its diagnostic capabilities.
Question 18

How does Mist determine the location of clients in an Indoor setting?
Understanding Location Determination in Mist:
Mist uses advanced methods to determine the location of clients in an indoor setting.
Possible Methods:
Triangulation: Uses angles to determine position, but not typically used by Mist.
GPS: Not feasible indoors due to signal limitations.
Probability Surface: Involves calculating the probability of a client's location, but not the primary method used.
Trilateration: Uses the distance from multiple known points to determine the exact location.
Mist's Method:
Mist primarily uses trilateration to determine the location of clients by measuring the distance from at least three access points.
Question 19

Which two Mist Ul options are available to receive notifications of Mist cloud status changes? (Choose two.)
Notification Options in Mist UI:
Mist provides several options for receiving notifications about Mist cloud status changes.
Available Notification Methods:
SNMP: Typically used for network management but not a primary method for Mist notifications.
RSS: Not commonly used for real-time notifications.
Slack: Mist can integrate with Slack to provide notifications directly to communication channels.
Email: Mist can send email notifications about cloud status changes.
Conclusion:
The correct answers are C (Slack) and D (Email).
Mist Documentation on Notifications: Mist Documentation
Question 20

AP is connected lo your wired network but Is not claimed to your organization. Which type of AP would be a possible security threat in this scenario?
Types of APs and Security Threats:
Understanding different types of access points and their potential security threats.
Access Point Types:
Neighbor AP: An access point that belongs to a neighboring network and is not necessarily a security threat.
Rogue AP: An unauthorized access point connected to the wired network, posing a significant security threat.
Spoofed AP: An access point that mimics a legitimate one, but typically does not involve being connected to the network.
Honeypot AP: An access point set up to lure attackers, not necessarily a threat unless used maliciously.
Identifying the Threat:
An AP connected to your wired network but not claimed to your organization is considered a rogue AP and poses a security threat.
Conclusion:
The correct answer is B.
