Sample Questions

Question 1

What is the primary function of a network firewall?

A. Encrypt traffic flowing between two endpoints over an untrusted network medium

B. Cache static content close to end users for low-latency content delivery to clients

C. Allow or block traffic based on defined rules — source/destination/port/protocol

D. Authenticate user identity before granting access to internal corporate applications

✓ Correct Answer: C

A firewall enforces traffic policy: allow or deny based on rule matches. A describes VPN/TLS. B describes CDN. D describes IAM/SSO.

Question 2

What is the difference between a stateful and a stateless firewall?

A. Stateful firewalls are slower because they encrypt traffic; stateless firewalls do plaintext inspection, in typical production scenarios

B. Stateful and stateless firewalls are synonyms — both terms refer to identical filtering behavior, under common configurations

C. A stateful firewall tracks connection state (e.g., established TCP); stateless evaluates each packet independently

D. Stateful firewalls work on TCP; stateless firewalls work on UDP for protocol coverage, as described in standard reference material

✓ Correct Answer: C

Stateful firewalls maintain a connection table and allow return traffic automatically. Stateless evaluates each packet against rules. C is correct. B, A, and D misdescribe.
