300-720 Exam Dumps : Securing Email with Cisco Email Security Appliance (300-720 SESA)

Spam threshold is a setting that determines the minimum score that a message must have to be classified as spam by Cisco ESA. The lower the threshold, the more aggressive the spam detection is.

The maximum attachment size to scan is a configuration on the scan behavior that determines the maximum size of an attachment that Cisco ESA will scan for viruses and malware. If an attachment exceeds this size, Cisco ESA will apply the configured action for unscannable messages, such as deliver, drop, or quarantine.

To allow the attachment to be scanned on the Cisco ESA, this configuration must be updated to a larger value than the attachment size, which is 10 MB according to the message header.

The other options are not valid configurations to allow the attachment to be scanned on the Cisco ESA, because they do not affect the maximum attachment size to scan.
