Question

which network devices rely on access control lists (acl) to permit network connections? [choose all that apply]

Answer 1

Devices like routers, firewalls, and Layer 3 switches use Access Control Lists (ACLs) to manage network traffic and enhance security.

Step-by-step explanation:

Network devices that rely on Access Control Lists (ACLs) to permit network connections include routers, firewalls, and some types of switches. ACLs are used to filter traffic based on various criteria such as IP addresses, protocol type, port numbers and other factors to ensure that only authorized users and devices can access certain areas within a network.

Routers use ACLs to control the flow of traffic between different network segments, determining whether to forward or drop packets based on the rules specified within the list. Firewalls, which are dedicated security devices, use ACLs extensively to permit or deny traffic into or out of a network. Finally, Layer 3 switches, which operate at the network layer and have routing capabilities, can also implement ACLs to apply security policies to inter-VLAN traffic within a network.

Answer 2

Access Control Lists (ACLs) are used by routers, firewalls, and advanced switches to regulate network traffic and enforce security policies by permitting or denying connections based on predefined rules.

Step-by-step explanation:

Access Control Lists (ACLs) play a crucial role in network security and management. They are employed by various network devices to control the flow of traffic, generally based on a set of rules that define which traffic to permit or deny on a network.

Network devices that rely on ACLs to permit network connections include:

Routers: Routers use ACLs to control the flow of traffic between different network segments, applying policies to route packets based on IP addresses and port numbers.

Firewalls: Firewalls leverage ACLs as a fundamental component of their security mechanisms to determine which packets are allowed or blocked in or out of the network.

Switches: Some advanced switches use ACLs to filter traffic at the data link layer, providing more granular control over network access and segmentation.

Additionally, other devices like load balancers and intrusion prevention systems can also use ACLs to enforce access policies and protect against unwanted traffic.
