Which two features are used to configure Cisco Secure Email Gateway with a multilayer approach to fight viruses and malware? (Choose two.)

Cisco Secure Email Gateway (formerly ESA) integrates multiple antivirus engines, such as the Sophos engine, to provide a multilayered defense using signature-based and heuristic detection methods against viruses and malware.

A whitelist allows email from trusted senders or domains to bypass certain checks, which is a policy control, but it is not a primary feature for actively detecting and fighting unknown viruses and malware.

RAT (Remote Access Trojan) is a type of malware, not a feature or component of the Cisco Secure Email Gateway used to combat malware.

Outbreak Filters provide an additional layer of defense by leveraging real-time threat intelligence to detect and block new, emerging email threats and malware outbreaks before traditional antivirus signatures are updated.

DLP (Data Loss Prevention) is a feature focused on preventing sensitive information from leaving the organization via email, rather than detecting and blocking incoming viruses and malware.
