Question 1

Which two statements correctly describe Mist claim codes and activation codes? (Choose Two.)

AAn activation code is primed on a slicker on the AP.

BClaim codes may be used to claim only one AP.

CActivation codes may be used to claim multiple APs at once.

DClaim codes may be used to claim multiple APs at once.

Answer : B, C

Claim Codes: Claim codes are unique to each AP and can be used to claim only one AP at a time. This ensures each device is correctly registered and managed individually within the Mist system.

Activation Codes: Activation codes can be used to claim multiple APs at once, facilitating bulk onboarding and simplifying the setup process for large deployments.

Question 2

....the correct lime zone for a Mist site provides which benefit?

Aenablement of remote access to the site during specific time slots

Bfacilitation of troubleshooting by aligning event timestamps with local time

Csynchronization of device clocks for accurate scheduling of events

Doptimization of network performance based on time-of-day usage
Time Zone Importance: Setting the correct time zone for a Mist site ensures that all events and logs are timestamped accurately according to the local time of the site. This is crucial for effective monitoring and troubleshooting.
Facilitation of Troubleshooting: By aligning event timestamps with the local time, network administrators can correlate events more easily with specific incidents reported by users, thereby simplifying the troubleshooting process.

Answer : B

Question 3

Which two Wi-Fi related SLEs are visible in the Mist UI? (Choose two.)

ASwitch Health

BCapacity

CApplication Health

DThroughput

Answer : B, D

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.

Question 4

...are asked to enable Mist management at an existing site with previously configured EX3400 brownfield switches, and to add a new greenfield switch, which statement is correct in this scenario?

AYou can mix brownfield switches and greenfield switches as long as they are running a Mist-supported version of Junos.

BYou cannot mix greenfield and brownfield switches at the same site.

CBrownfield switches can be adopted but not managed.

DYou can mix brownfield switches and greenfield switches at the same site, but only if they are running the same version of Junos.

Answer : A

In the context of Mist management, 'brownfield' switches refer to those that are already configured and deployed in a network, while 'greenfield' switches are new and have no pre-existing configuration.

Mist supports the integration and management of both brownfield and greenfield switches within the same site. The crucial requirement is that all switches, regardless of their initial state, must be running a version of Junos that is supported by Mist.

This compatibility ensures that Mist can apply policies, configurations, and monitoring uniformly across all devices, facilitating a seamless management experience.

Question 5

Which two Mist Ul options are available to receive notifications of Mist cloud status changes? (Choose two.)

ASNMP

BRSS

CSlack

DEmail

Answer : C, D

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).

Question 6

Which two statements are true about packet captures on an AP? (Choose two.)

AOnly wireless packets can be captured.

BWireless and wired packets can be captured.

CThe involved APs are taken out of service.

DThe involved APs remain in service.

Answer : B, D

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.

Question 7

Which SLE reports RF interference?

ACapacity

BCoverage

CRoaming

DAP Health

Answer : B

In Mist's Service Level Expectations (SLE) framework, the Coverage SLE is responsible for reporting on RF interference.

The Coverage SLE monitors the strength and quality of the wireless signal, ensuring that clients are receiving adequate coverage throughout the network. It also identifies areas where RF interference might be degrading the signal quality.

By tracking RF interference, the Coverage SLE helps administrators diagnose and mitigate issues that could impact wireless performance and user experience.
