What does VACL stand for?

  1. Virtual Access Control List

  2. VLAN Access Control List

  3. VLAN Address Configuration List

  4. Variable Access Control List

The correct answer is: VLAN Access Control List

VACL stands for VLAN Access Control List. This term refers to a security feature in a network that allows you to control the flow of traffic within a specific VLAN. By using VACLs, network administrators can enforce security policies by permitting or denying certain types of traffic based on predefined criteria, such as source and destination IP addresses, protocols, or ports. Using a VACL enhances the ability to manage access controls and ensure that only authorized traffic is allowed within VLANs. This is particularly useful in environments where segmentation of network traffic is essential for security and performance. The other options do not accurately define VACL: a Virtual Access Control List may suggest a more general concept but lacks the specificity to VLANs; VLAN Address Configuration List implies a focus on IP address assignments rather than traffic filtering; and Variable Access Control List does not exist as a recognized term in networking practice. Thus, VLAN Access Control List accurately captures the essence and function of VACL in network management.
