What is the correct format to use when specifying a configuration for a standard numbered ACL?

The correct format for specifying a configuration for a standard numbered Access Control List (ACL) is indeed centered around using the access-list command, which is found in the configuration mode of a Cisco device.

In this context, the access-list command allows network administrators to specify traffic that should be permitted or denied based on the source IP addresses. When defining a standard ACL, the syntax requires the list number, whether the action is permit or deny, and the source IP address, which can be followed by a wildcard mask. The wildcard mask indicates which bits of the address should be explicitly matched and which bits can be ignored, providing flexibility in matching different ranges of IP addresses.

Standard ACLs only focus on the source IP address, and this command structure correctly illustrates that by including the required elements. Therefore, using the format of "access-list number {deny | permit} ip wildcard-mask" accurately represents how to create such ACLs.

This highlights the need to understand the components of ACL syntax and the specific features of standard ACLs, which reinforce the appropriate selection for the given question.
