Which ACL command is used to configure a basic IPv4 access-control list on Citrix ADC?

• A. Add NS ACL
• B. Add NS ACL6
• C. Add NS SimpleACL
• D. Add NS SimpleACL6

Answer: (A)

ACLs on Citrix ADC filter traffic by IP addresses, with separate commands for IPv4 and IPv6. To create a basic IPv4 ACL, you use the standard IPv4 ACL command, which is add ns acl. This command defines a regular access-control list that can contain multiple rules specifying source and destination IPs (and other fields) and the action to take. The IPv6 variant (add ns acl6) is for IPv6 traffic, while the simple ACL options (add ns simpleacl and add ns simpleacl6) refer to a simpler, less feature-rich form of ACLs and aren’t the default method for configuring a basic IPv4 ACL. So for a straightforward IPv4 ACL, add ns acl is the appropriate choice.
