Juniper JN0-750 Free Dumps (Part 2, Q41-Q70) of V10.02 Are Also Available: Helping You Check the Most Current Materials

1. A Network Architect is choosing a tool to automate the configuration of a large number of Juniper EX switches managed by Mist. The primary requirement is that the tool should be agentless and use a human-readable data format for defining the configuration tasks. The operations team is already familiar with this tool for managing servers.

Which automation tool fits these requirements?

2. A Compliance Officer has written a complete Python script to generate a compliance report. The script is complex and will be run by other team members. To ensure maintainability and prevent errors, the script needs to be able to handle cases where an API call might fail, for example, due to a temporary network issue.

Consider the following code snippet using the `requests` library (which is used by `mistapi`):

import requests

try:

response = requests.get("https://api.mist.com/api/v1/orgs/{org_id}/sites", timeout=10)

response.raise_for_status() # Raise an exception for bad status codes (4xx or 5xx)

# ... process successful response ...

except requests.exceptions.HTTPError as err:

print(f"HTTP Error: {err}")

except requests.exceptions.RequestException as e:

print(f"An unexpected error occurred: {e}")

What is the purpose of the `try...except` block in this Python script?

3. An Automation Developer wants to create a proactive alert. The goal is to trigger a Webhook if the "Coverage" SLE for any AP at a specific site drops below 80% for more than 30 minutes.

What is the most efficient way to create this Day 2 automation?

4. A Network Architect needs to quickly test a new Mist API endpoint they saw in the documentation without writing any code. They want to make a `GET` request, inspect the headers and the JSON response.

Which tool is most suitable for this interactive, ad-hoc API exploration?

5. A Guest User Manager is responsible for creating and managing guest PSKs (Pre-Shared Keys). They want to automate the creation of a new guest PSK that is valid for 24 hours.

Which of the following API endpoints would be used to create a new, multi-use PSK associated with a specific WLAN? (Choose 2.)

6. A Compliance Officer is writing a Python script to verify that all sites within their organization have a specific, mandated WLAN template applied. The script must first get a list of all sites, then iterate through each site to check its settings.

The script successfully gets a list of sites, and one site object looks like this in Python:

{

"id": "a1b2c3d4-e5f6-7890-1234-567890abcdef",

"name": "Branch-Office-101",

"wlan_template_id": "f0e9d8c7-b6a5-4321-fedc-ba9876543210",

"network_template_id": "c1d2e3f4-a5b6-7890-1234-abcdef123456"

}

How would the script access the ID of the WLAN template assigned to this site?

7. A Network Architect is preparing a Zero-Touch Provisioning (ZTP) workflow for a new branch office. The workflow involves on-site staff simply plugging in new APs and switches.

For ZTP to function correctly, which of these Day 1 automation tasks MUST be completed in the Mist cloud *before* the devices are powered on at the site?

8. A Network Administrator is reviewing the Wireless Assurance dashboard for a site and notices the "Time to Connect" SLE is red.

What does a red "Time to Connect" SLE indicate?

9. An Automation Developer is using a Python script to analyze wireless performance. The script has retrieved a list of client session events from the Mist API.

One event object is as follows:

{

"type": "MARVIS_ACTION_CONSISTENTLY_FAILING_CLIENT",

"timestamp": 1678886400,

"client_mac": "AA:BB:CC:DD:EE:FF",

"failure_type": "DHCP"

}

What does this specific event object indicate?

10. A Network Administrator needs to onboard a new EX switch using Zero-Touch Provisioning (ZTP). The switch will be installed at a remote branch office.

For the ZTP process to work automatically when the switch is powered on, which Day 1 tasks MUST be completed in the Mist portal beforehand?

11. A Network Architect is writing an Ansible playbook to deploy a new Mist site.

The playbook has three main tasks:

1. Create the site using the `mist.mcs.site` module.

2. Create a WLAN template using the `mist.mcs.wlan_template` module.

3. Apply the template to the site by updating the site with the `mist.mcs.site` module again.

How does Ansible handle the order of these operations?

12. A NOC Operator is troubleshooting a widespread report of "bad Wi-Fi" at a critical branch office. The operator suspects a systemic issue, like a failing DNS or DHCP server, is affecting many users simultaneously. They need to see a consolidated view of recent, major network problems.

Which Mist Webhook subscription would provide the most relevant, high-level alerts for this type of investigation?

13. An Automation Developer is automating the process of adding a new Juniper EX switch to a site. The script has already claimed the switch into the organization's inventory.

What is the next mandatory API call to ensure the switch can be configured for a specific site?

14. An Automation Developer is tasked with creating a Python script to automate the setup of a new branch office. The script must create a new site, create a standard WLAN template for the branch, and apply this template to the new site.

Which of the following represents the correct order of API calls to achieve this?

15. An IT Manager wants to be notified about a very specific type of security event: when a wireless client is repeatedly failing 802.1X authentication, which could indicate a misconfigured device or a potential security attack.

When creating the Alert Template, which event type should the manager select as the trigger?

16. A Network Administrator needs to share a weekly summary of the wireless "Coverage" SLE with their manager, who does not have a Mist account.

Which features of the Mist Insights platform can be used to automate this? (Select all that apply.)

17. An Automation Developer is creating a "cleanup" script.

After a temporary site is no longer needed, the script must perform the following actions in the correct order:

1. Unassign all devices from the site, returning them to the organization's inventory.

2. Delete the site itself.

What is the correct sequence of API calls to perform this cleanup?

18. A Network Administrator is creating a standardized set of variables for their Ansible playbooks that automate Mist configurations. The variables are stored in a file named `vars.yml`.

A snippet of the file is as follows:

site_details:

- name: "HQ-Site"

address: "1

Corporate Drive"

timezone:

"America/New_York"

- name: "Branch-Site"

address: "200

Business Park"

timezone:

"America/Chicago"

What data structure format is being used in this file?

19. A Network Architect needs to perform a simple, repetitive task every morning: generate a list of all access points that are currently offline across the entire organization. They want to run a single command from their shell to get this list.

Which Mist automation tool is best suited for this kind of simple, command-line, ad-hoc task?

20. A Network Administrator is using the Mist API to automate the generation of a performance report. They need to retrieve the same data that is shown on the "Application Insights" dashboard for a site.

Which family of API endpoints should the administrator's script query?

21. A Network Administrator is using the Mist API to automate a weekly performance report. The script needs to determine if the "Successful Connects" wireless SLE for a site met its goal of 95% for the past week.

The script makes an API call to `GET /api/v1/sites/{site_id}/sle/wifi/summary` and receives this response:

{

"start_time": 1678272000,

"end_time": 1678876800,

"sle_metrics": {

"time_to_connect": {

"success_rate": 96.2,

"failure_rate": 3.8

}

}

}

Based on this data, what conclusion can the script draw?

22. A Network Architect needs to create a custom report showing the top 10 applications by bandwidth usage across their entire organization for the last 30 days.

How can they access this information via the Mist dashboard?

23. An IT Manager has configured an email alert for "AP Offline" events. They notice that when a switch that powers 10 APs goes offline, they receive 10 separate email notifications, one for each AP. They want to consolidate this into a single notification for the root cause.

How can they refine the alerting to be more intelligent and less noisy?

24. An Automation Developer is creating a custom dashboard to display the top 5 wireless clients with the highest data usage over the past week for a specific site.

Which API endpoint should the developer query to obtain this data?

25. A Network Architect is analyzing client connection issues at a high-density lecture hall. They need to determine the primary reason why clients are failing to connect to the "University-WiFi" SSID.

Which Mist dashboard or tool provides the most direct and aggregated root cause analysis for connection failures?

26. An Automation Developer is making a `GET` request to the Mist API to retrieve a list of sites in their organization. The organization has over 200 sites, but the API response only includes the first 100.

import requests

headers = {"Authorization": "Token MY_API_TOKEN"}

url = "https://api.mist.com/api/v1/orgs/MY_ORG_ID/sites"

response = requests.get(url, headers=headers)

sites = response.json()

# len(sites) is 100

What must the developer do to retrieve the next page of results?

27. A Network Architect is using a Python script to automate the creation of a new site and immediately apply a standard set of WxLAN policies for guest and IoT segmentation.

What is the correct order of operations for the script to follow?

28. A Network Administrator is analyzing the "Client Density" insight for a specific floorplan. The dashboard shows a heatmap with several areas colored red, indicating high client counts.

What is the primary data source used to generate this client density heatmap?

29. A Network Administrator is creating a new guest network. The design requires a custom-branded Captive Portal (defined in a Portal Template) to be used by the guest WLAN (defined in a WLAN Template).

Which statement accurately describes the dependency and order of operations?

30. A Network Architect is reviewing a Marvis Action for "DHCP Failure" that is impacting several wireless clients at a site. To perform a root cause analysis, they need to look at data from multiple sources.

Which of the following data and statistics should be analyzed to effectively troubleshoot this issue? (Select all that apply.)
