A Network Administrator receives a JSON payload from a Mist Webhook. They load it into a Python variable named `data`.
{
"topic": "device-down",
"events": [
{
"mac": "5c5b35000001",
"type": "AP_DISCONNECTED"
},
{
"mac": "5c5b35000002",
"type": "AP_DISCONNECTED"
}
]
}
Which of the following statements about the resulting Python data structure are true? (Select all that apply.)
- A . The top-level `data` variable is a Python dictionary.
- B . To access the MAC address of the first event, you would use `data["events"][0]["mac"]`.
- C . The value of `data["events"]` is a Python list.
- D . The value of `data["topic"]` is the string `"device-down"`.
- E . The entire `data` variable is a Python list.
After a successful deployment, the Solutions Consultant wants to add a final step to their automation script for verification. The script should programmatically confirm that a specific switch has successfully connected to the Mist cloud and is reporting an "Up" status.
Which API endpoint provides the real-time device status information needed for this verification?
- A . `GET /api/v1/sites/{site_id}/settings`
- B . `GET /api/v1/sites/{site_id}/stats/devices`
- C . `GET /api/v1/orgs/{org_id}/inventory`
- D . `GET /api/v1/orgs/{org_id}/audits`
A Network Administrator wants to automate a Day 2 task: every week, a script should check all APs in the organization and reboot any AP that has an uptime greater than 90 days.
Which combination of tools and APIs would be used for this workflow?
- A . 1. A Marvis query for "list APs with uptime > 90 days". -> 2. An Alert Template to trigger the reboot.
- B . 1. `GET /api/v1/orgs/{org_id}/stats/devices` to get the status and uptime for all APs. -> 2. A Python script to check the uptime. -> 3. `POST /api/v1/sites/{site_id}/devices/{device_id}/reboot` for the targeted APs.
- C . 1. A Webhook subscribed to the `device-uptime` topic. -> 2. A script to trigger the reboot.
- D . 1. `GET /api/v1/orgs/{org_id}/inventory`. -> 2. `mist-cli` to reboot the APs.
A Network Architect wants to ensure high availability for the authentication service. The design uses two RADIUS servers in a primary/backup configuration.
Which configuration objects and settings are required to implement this? (Select all that apply.)
- A . A single `authenticator` object of type `radius` in the Access Assurance policy.
- B . An Alert Template to notify an administrator if the primary RADIUS server fails.
- C . Two separate `authenticator` objects, one for each RADIUS server.
- D . A Mist Edge cluster to load balance the RADIUS traffic.
- E . A list or array within the `authenticator` object containing the IP addresses of both the primary and backup RADIUS servers.
An Automation Developer is investigating a "Consistently Failing Clients" Marvis Action. They need to write a script that can automatically de-authenticate a client that has been identified as failing.
Which Mist APIs would the script need to use to accomplish this? (Select all that apply.)
- A . An API call to `DELETE /api/v1/sites/{site_id}/clients/{client_mac}` to remove the client from the system.
- B . An API call to `PUT /api/v1/sites/{site_id}/devices/{ap_mac}` to reboot the AP.
- C . An API call to `GET /api/v1/sites/{site_id}/marvis/actions` to retrieve the details of the failing client.
- D . An API call to `POST /api/v1/sites/{site_id}/clients/unauthorize` to disconnect the client.
- E . A Webhook subscription to the `marvis-actions` topic.
A Guest User Manager is deploying a new site for teleworkers using a fully templated approach. The site requires a site-specific PSK for the main WLAN.
Which steps represent the correct order of operations to achieve this?
- A . 1. Create Org-level WLAN Template -> 2. Create Site -> 3. Create Site-level PSK -> 4. Apply Template
- B . 1. Create Site -> 2. Create Org-level WLAN Template -> 3. Apply Template to Site -> 4. Create Site-level PSK for the WLAN
- C . 1. Create Site-level PSK -> 2. Create Org-level WLAN Template -> 3. Create Site -> 4. Apply Template
- D . 1. Create Org-level WLAN Template -> 2. Create Site-level PSK -> 3. Apply Template to Site -> 4. Create Site
A Network Administrator needs to modify the configuration of hundreds of switches that are already deployed and operational. The change involves adding a new VLAN to a specific set of ports on each switch. They want to do this programmatically.
Which tool is best suited for this Day 2, at-scale, configuration modification task?
- A . Using the Dynamic Packet Capture tool to inject new configuration commands.
- B . A Python script that uses the Mist REST API to iterate through the list of switches and `PUT` the updated configuration to their respective Device Profile or device-level settings.
- C . Using `mist-cli` to manually update each switch one by one.
- D . Using the individual switch "Shell" access from the Mist UI to run Junos commands.
Guests (Wireless): Visitors to the campus. Must self-register through a captive portal. They should be completely isolated from all internal university networks.
Mist Policy Objects:
– A single, comprehensive Access Assurance Policy.
– A RADIUS server object pointing to the university’s central authentication server.
– Multiple WxLAN policies (e.g., "Faculty-Access," "Student-Access," "IoT-Access," "Guest-Access") that define the firewall rules for each role.
SCENARIO END
Referring to the scenario, which Mist configuration object is the central enforcement point for defining the different authentication methods (802.1X, MAB, Portal) and assigning the initial user roles (Faculty, Students, IoT, Guests)?
- A . The Access Assurance Policy
- B . The WLAN Template
- C . The WxLAN Policy
- D . The Switch Template
A Guest User Manager is creating a new guest WLAN using a site-level template. The WLAN needs to use a WxLAN policy to enforce network segmentation.
When building the automation script, what is the correct order for creating these configuration objects?
- A . 1. Create Site -> 2. Create WxLAN Policy -> 3. Create WLAN in template
- B . 1. Create WxLAN Policy -> 2. Create WLAN in template (referencing the policy) -> 3. Create Site and apply template
- C . 1. Create WLAN in template -> 2. Create WxLAN Policy -> 3. Apply policy to WLAN
- D . 1. Create WLAN in template -> 2. Create Site -> 3. Create WxLAN Policy
