What are two differences and benefits of packet filtering, stateful firewalling, and deep packet inspections? (Choose two.)

The correct answer is B. Deep packet inspection operates up to Layer 7, and packet filtering operates on Layer 3 and 4 of E. Deep packet Inspection is capable of malware blocking, and packet filtering is not.. Packet filtering firewalls inspect packets based on Layer 3 (IP addresses) and Layer 4 (protocols and ports) information. Deep Packet Inspection (DPI) goes further, analyzing traffic up to Layer 7 (application layer), enabling inspection of content within the packets. DPI can det

Explanation

Packet filtering firewalls inspect packets based on Layer 3 (IP addresses) and Layer 4 (protocols and ports) information. Deep Packet Inspection (DPI) goes further, analyzing traffic up to Layer 7 (application layer), enabling inspection of content within the packets. DPI can detect and block malicious content, malware, or application-level threats by analyzing packet payloads, which is beyond the capability of simple packet filtering firewalls.
