What is the range of numbers that can be used to identify standard numbered ACLs?

The range of standard numbered Access Control Lists (ACLs) is defined as 1 to 99 and 1300 to 1999. This numbering system is utilized primarily to identify different types of ACLs within Cisco IOS.

Standard ACLs are those that filter traffic based solely on the source IP address. Utilizing the specified range allows network administrators to create multiple ACLs while avoiding conflicts with extended ACLs, which have their own distinct range. The range of 1300 to 1999 is available to provide additional flexibility and future-proofing for ACLs as networks grow.

The other choices either include incorrect ranges or do not align with Cisco’s standard classification of ACLs, which is why they are not valid selections. Understanding this range is essential for implementing and managing ACLs effectively in a networking environment.
