B. Application-level gateway
C. Stateful inspection
D. Circuit-level gateway

What type of firewall evaluates the context of network traffic to make allow and deny decisions?
A. Application-level gateway
B. Stateful inspection
C. Circuit-level gateway
D. Static packet-filtering
Chapple, Mike; Stewart, James Michael; Gibson, Darril. (ISC)2 CISSP Certified Information Systems Security Professional Official Study Guide (p. 518). Wiley. Kindle Edition.
B. Stateful inspection
Explanation:
Statefull inspection firewalls evaluate the state or the context of network traffic. By examining source and destination addresses, application usage, source of origin, and relationship between current packets and the previous packets of the same session, stateful inspection firewalls are able to grant a broader range of access for authorized users and activities and actively watch for and block unauthorized users and activities.

Which of the following is not true regarding firewalls?
A. They are able to log traffic information.
B. They are able to block viruses.
C. They are able to issue alarms based on suspected attacks.
D. They are unable to prevent internal attacks.
Chapple, Mike; Stewart, James Michael; Gibson, Darril. (ISC)2 CISSP Certified Information Systems Security Professional Official Study Guide (p. 519). Wiley. Kindle Edition.
B. They are able to block viruses.
Explanation:
Most firewalls offer extensive logging, auditing, and monitoring capabilities as well as alarms and even basic IDS functions. Firewalls are unable to block viruses or malicious code transmitted through otherwise authorized communication channels, prevent unauthorized but accidental or intended disclosure of information by users, prevent attacks by malicious users already behind the firewall, or protect data after it passed out of or into the private network.
