Cisco Catalyst Center uses its Event Notifications framework to alert operations teams when Assurance detects client, device, or wireless issues. The correct workflow is not a simple email-address entry under Issue Settings; it is an event subscription that binds selected issue events to a notification channel such as EMAIL. Cisco’s Catalyst Assurance documentation states that, when a specific Assurance issue is triggered and its status changes, Assurance can generate REST or email notifications, and the workflow opens thePlatform > Developer Toolkit > Event Notificationswindow from Manage Subscription. The same guide confirms that EMAIL is one of the supported notification channels and that the EMAIL notification details include sender, recipient, and subject fields. Cisco’s Platform User Guide also defines Event Notifications as the place to “view and subscribe to specific events” and gives the GUI path asPlatform > Developer Toolkit > Event Notifications. Therefore, option B is correct. SMTP/email destination configuration may be a prerequisite, but the required alerting action is creating the event notification subscription.
