NEW QUESTION # 35
A user has reported a network outage. After locating the user, you find that the switch interface facing the user is down but there is no alert in the Mist UI. You want to ensure that in the future, you receive an alert when a switch interface is down. You have already verified that the Critical Switch Port Down alarm is configured and enabled on the Alerts Configuration page.
In this scenario, which action in the Mist UI will satisfy the requirement?
- A. Navigate to the switch in the Mist UI and modify the Port Configuration to enable the Up/Down Port Alerts setting for the interface.
- B. Navigate to the switch in the Mist UI and modify the Port Profile configuration to enable Persistent (Sticky) MAC Learning for the Port Profile.
- C. Disable the Critical Switch Port Down alarm on the Alerts Configuration page.
- D. Enable the Critical Switch Port Up alarm on the Alerts Configuration page.
Answer: A
Explanation:
To ensure that you receive alerts when a switch interface goes down, you need to enable the Up/Down Port Alerts setting for the specific interface. This setting can be configured by navigating to the switch within the Mist UI and modifying the port configuration. Enabling this setting ensures that any changes in the port status, such as going down, will trigger an alert.
This is critical for proactive network monitoring and to promptly address any connectivity issues.

Click the Exhibit button. The exhibit displays the connection flow for an API interaction sequence.
Which API type is displayed?
- A. Webhook
- B. WebSocket
- C. SOAP
- D. RESTful
Answer: A
Explanation:
The diagram displays the concept of a webhook interaction.
The client sends an initial request to the server (Step 1: Request/Response).
After that, the server asynchronously sends events or updates to the client (Steps 2 and 3: Event notifications), without requiring the client to poll for updates continuously.
This asynchronous "push" behavior is characteristic of webhooks, where the server pushes updates to the client.
