,Section A - Firewall Fundamentals AND Architectures
Q1.
In a stateful firewall implementation, which of the following best describes the behavior
when a TCP packet with the ACK flag set arrives that does not match an existing
connection in the state table?
A. The firewall forwards the packet if it is B. The firewall drops the packet because it
part of an established session in a different is not part of a valid established session.
VLAN.
C. The firewall creates a new state entry D. The firewall sends a TCP RST to the
and forwards the packet to the destination. source to terminate the invalid session.
Correct: B - The firewall drops the packet because it is not part of a valid established
session.
Rationale:Stateful firewalls maintain a state table of active connections. An ACK packet
without a corresponding state entry is considered unsolicited and is typically dropped to
prevent evasion and spoofing. Creating a new state would allow unauthorized traffic, and
sending RST is not the standard action for such packets.
Q2.
An organization deploys a next-generation firewall (NGFW) with application identification
enabled. Which of the following represents the most significant security advantage of this
feature over traditional port-based filtering?
A. It allows the firewall to block applications B. It reduces the need for intrusion
regardless of port or protocol. prevention signatures.
C. It eliminates the risk of malware hidden D. It enables the firewall to decrypt all
inside allowed applications. SSL/TLS traffic automatically.
Correct: A - It allows the firewall to block applications regardless of port or protocol.
Rationale:NGFWs use application identification to classify traffic based on application
signatures and behavior, not just port numbers. This allows blocking applications even if they
use non-standard ports or protocols. It does not eliminate the need for IPS signatures, cannot
stop all malware, and does not automatically decrypt traffic without configuration.
Q3.
In a distributed denial-of-service (DDoS) attack, which firewall configuration is most
effective at mitigating a SYN flood targeting a public web server?
A. Enable stateful inspection with a low SYN B. Implement an ACL that blocks all inbound
timeout threshold. traffic on port 80.
Page 3
, Section A - Firewall Fundamentals AND Architectures
C. Deploy a stateless firewall with a simple D. Use a proxy-based firewall that only
allow-all policy. inspects HTTP payloads.
Correct: A - Enable stateful inspection with a low SYN timeout threshold.
Rationale:Stateful inspection with a low SYN timeout threshold allows the firewall to drop
half-open connections quickly, freeing resources. Blocking all traffic on port 80 would cause a
denial of service to legitimate users. Stateless firewalls cannot track connection states, and
proxy-based inspection does not specifically address SYN floods.
Q4.
Which of the following is the primary weakness of a packet-filtering firewall that operates
only at the network layer?
A. It cannot filter traffic based on application B. It is unable to log traffic for auditing
data. purposes.
C. It requires a separate proxy for each D. It does not support network address
application. translation (NAT).
Correct: A - It cannot filter traffic based on application data.
Rationale:Packet-filtering firewalls inspect only header information (IP addresses, ports,
protocols) and do not examine the payload or application layer data. This limitation allows
attacks that use legitimate ports for malicious purposes. They can log traffic, do not require
proxies (that's for proxy firewalls), and can support NAT.
Q5.
In a VPN using IPsec, which protocol provides the actual encryption of the payload data?
A. AH (Authentication Header) B. ESP (Encapsulating Security Payload)
C. IKE (Internet Key Exchange) D. ISAKMP (Internet Security Association
and Key Management Protocol)
Correct: B - ESP (Encapsulating Security Payload)
Rationale:ESP provides encryption and optional authentication for the payload, ensuring
confidentiality. AH only provides authentication and integrity without encryption. IKE and
ISAKMP are used for key exchange and negotiation, not for data encryption.
Q6.
An enterprise network uses a demilitarized zone (DMZ) to host public-facing services.
Which of the following firewall rules is most appropriate for controlling traffic from the
internet to the DMZ?
