Understanding Cisco Cybersecurity Fundamentals (SECFND, legacy) — Question 35

Which three of the following statements are true regarding ACLs? (Choose three.)

Answer options

• A. ACLs provide packet filtering for routers and firewalls to protect network segments that require more security.
• B. ACLs are used to perform stateful packets inspections and filtering on routers and firewalls.
• C. ACLs provide a basic level of security and control the packets that pass through the routers or firewalls, preventing them from getting to the different parts of the network.
• D. At a minimum, it is important to configure the ACLs on the network edge routers or firewalls.
• E. ACLs can be applied only at the inbound direction and not at the outbound direction.

Correct answer: A, C, D

Explanation

The correct answers A, C, and D highlight the primary functions of ACLs in providing security and controlling traffic in network devices. Option B is incorrect because ACLs do not perform stateful packet inspection; that is typically a feature of firewalls. Option E is also false, as ACLs can be applied in both inbound and outbound directions.
