Q

Which two statements are true about the Mist Cloud? (Choose two)

A

The Mist Cloud manages devices and collects data over the same connection & Application payload data is not stored

(Juniper hosts the Mist AI service in the cloud. All client and infrastructure telemetry data collected on your network is sent to the Mist cloud over TCP 443 or L2TP connections where it is analyzed in real-time by Mist’s microservices hosted in the cloud. Device configuration changes made by admins on the Mist portal are pushed from the Mist cloud down to managed devices over those same connections. Mist does not store application payload data.)

Q

How does a juniper Mist AP detect a honeypot AP?

A

It detects that its SSID is also being advertised by a non-Mist AP.

(Mist APs have a third radio dedicated to scanning. This radio is used for detecting rogue, neighbor, and honeypot APs on both the 2.4GHz and 5 GHz radio bands. The third radio constantly monitoring for active SSIDs in the vicinity. SSID comparison: When the scanning radio detects an SSID matching one already configured on the MIST network, it triggers further investigation)

Q

How does Mist detect rogue APs?

A

by using the AP’s third dedicated radio (third dedicated radio = scanning radio)

18
Q

Which statements are true about a Mist organization? (Choose two)

A

The Organization ID can not be changed & The Organization Name can be changed

(Org ID never change - because referenced by the APIs for automation etc.)

19
Q

Which method enables Juniper Mist to claim multiple APs at once?

A

use activation code

20
Q

What are two requirements for the ZTP provisioning process for a Juniper EX Series switch? (Choose two)

A

a DHCP server & outbound Internet access

21
Q

Which statement defines the total user minutes?

A

The total number of minutes for which Mist has statistics for each client.

(User minutes are minutes that a client is connected to the network.)

22
Q

Which administrator role must you have to view audit logs?

A

Super User

23
Q

You want to obtain detailed information on a wireless client. In this scenario, which area would you use to accomplish this task?

A

Insights

(You can use Mist insights to gain detailed information about a wireless client. Details such as time it takes clients to connect, and roaming information can be found here.)

24
Q

You want to review client information about a specific AP. In this scenario, where in the UI would you look?

A

AP Insights

(The Mist insights section for an AP allows you to see client-specific info, such as DNS successes, gateway ARP successes, and authorization and reassociation events.)

25
Q

Which statement is correct about Mist SLEs?

A

A Mist SLE is comprised of multiple classifiers

(multiple classifiers to track different metrics. If an SLE metric does not meet its threshold, then this failure may be attributed to one of the classifiers to further understand where the failure occurred.)

26
Q

Referring to the exhibit, what percentage of connection attempts took longer than the 2 second goal? (Time to connect screen - stats: TTC - 88%, Successful Connects - 47%, coverage - 99%, Roaming - 95%, Throughput > 99%, Capacity - 92% & AP Health - 85%) — to the right Classifiers — Authorization - 5%, Internet Services 0%, Association 71% & DHCP - 24%

Bottom of screen: Success Rate – 88% 2.8 seconds avg.

A

12% - Success rate w/ 2 second goal = 88%…

(Exhibit displays an 88% success rate for connection attempts to take less than 2 seconds. This means that the number of connection attempts that took more than 2 seconds (in other words, were unsuccessful) was 12%)

27
Q

Using the Mist UI, which two actions are valid after performing a streaming packet capture? (Choose two)

A

View the list of captured packets & download the packet capture

(When you manually initiate a streaming packet capture in Mist, you can view the packet capture in real time in the UI. Once the packet capture has finished or has been stopped, you have the option to download the packet capture for up to 3 days)

28
Q

A user called a help desk to report a Wi-Fi issue. In this scenario, what information must be provided for Marvis to troubleshoot the issue? (Choose two)

A

the time of the incident & the MAC address of the client device

(When troubleshooting at client issue with Marvis you need to provide the MAC address of the client and set duration so it covers the time of the incident.)

29
Q

In the Latest Updates sections of Marvis Actions, how long are updates displayed?

A

7 days

(Updates are displayed only up to 7 days and are then removed from the Latest Updates section.)

30
Q

What is the purpose of the “Other Actions” section of the Marvis Actions dashboard?

A

To highlight actions that are less urgent and don’t require immediate action

(The Marvis Actions dashboard highlights issues that are high visibility and user-impacting and require immediate attention. Other actions = less urgent may be only impacting 1 client.)

31
Q

You want to use Marvis Actions to make sure that all of your APs are running on the same software. In this scenario, in the UI, you look under AP and which action?

A

Non-Compliant

32
Q

You want to determine where you have coverage issues in your network using Marvis Actions. Which Marvis Action category should you use in this situation?

A

AP

(Marvis Actions AP category reports: Offline, Health Check Failed, Non-compliant, Coverage Hole & Insufficient Capacity.)

33
Q

A user device sends signal information to the Mist Location Engine. In this scenario, what is expected from the Mist Location Engine?

A

coordinates

(The location sensor sends location data to the location engine, which processes information about a device’s X and Y coordinates. The location engine is a component of the location tracking system that runs in the cloud)

34
Q

Besides providing AP configuration status, for which other purpose is the LED used in the location design phase?

A

antenna orientation

(Mist APs must be mounted on the ceiling with the LED facing towards the ground. You cannot put a location AP on a wall (vertically), on top of objects, inside of objects or have LED facing up towards ceiling. The system assumes AP is always facing down, mounting AP otherwise will cause your location to be flipped & inaccurate.)

35
Q

How should APs be deployed for location-based services (LBS)?

A

with the LED facing the floor

36
Q

When using Mist’s location-based services (LBS), what is the accuracy of Wi-Fi location?

A

5 to 10 meters

(Wi-Fi location is accurate to a range of 5-10 meters. Asset visibility is accurate to a range of 3 to 5 meters. vBLE engagement is accurate to a range of 1 to 3 meters.)

37
Q

Which three HTTP methods are used in the Mist RESTful API function? (Choose three.)

A

DELETE, PUT & GET

(A REST client sends an HTTP request to a URL using a GET, POST, PUT, and DELETE)

38
Q

You attempt to log in to manage.mist.com, however you receive a 404 error from your browser. You are able to browse other public websites and you suspect a problem with manage.mist.com. In this scenario, which step would you take to immediately find out the status of the Mist cloud?

A

Visit https://status.mist.com

39
Q

What is an API endpoint?

A

the URL to which an API request is targeted

(API endpoint = destination URL for API call)

40
Q

A user is identified and authenticated based upon what information in an API call?

A

authorization token

(authorization token is used to authenticate API calls)
