Which two field can be used to create a new email alert within the Cisco Firepower Management center under Policies > Actions > Alerts tab? (Choose two.)

'Device' is typically a criterion used to define which events trigger an alert, not a configuration field for the email delivery itself.

'Source' is typically a criterion used to define which events trigger an alert, not a configuration field for the email delivery itself.

'Destination' is typically a criterion used to define which events trigger an alert, not a configuration field for the email delivery itself.

The 'From' field specifies the sender's email address that will appear on the alert emails, allowing recipients to identify the source of the notification. This is a standard and necessary component for email communication.

The 'Relay Host' field specifies the IP address or hostname of the SMTP server that the Firepower Management Center (FMC) will use to send the email alerts. This is crucial for the FMC to deliver notifications to the specified recipients.
