Huawei HCIA-Security V4.0 Sample Questions (Q115-Q120):

NEW QUESTION # 115
Which of the following are disadvantages of the packet filtering firewall?

A. The connection status list is dynamically managed.
B. Static ACL rules cannot meet dynamic security requirements.
C. The software implementation limits the processing speed, making the firewall vulnerable to DoS attacks.
D. An attacker can set the IP address of his/her host to an IP address permitted by a packet filter. In this way, packets from the attacker's host can easily pass through the packet filter.

Answer: B,C,D

Explanation:
Explanation From HCIA-Security documents:
A packet filtering firewall mainly makes decisions based on L3/L4 header information such as source
/destination IP address, protocol, and port, usually through static ACL rules . Because it does not deeply understand application behavior and typically does not track full session state like a stateful inspection firewall, it has several limitations.
A is a disadvantage because basic packet filtering is often implemented as rule-by-rule matching; under heavy traffic or intentionally flooded traffic, performance can degrade and the device may be pressured by DoS-style loads, especially if rules are long or the platform is resource-limited.
B is also a disadvantage: packet filtering that trusts only IP information can be bypassed by IP spoofing in certain scenarios, allowing traffic to appear as if it comes from an allowed address.
C is correct because packet filtering relies on static policies , which struggle to handle dynamic connections, complex services, and fine-grained user-based control.
D is not a disadvantage of packet filtering; dynamic connection status lists are a feature of stateful firewalls, not simple packet filters.
