Question:
Which statement describes a characteristic of standard IPv4 ACLs?
- They are configured in the interface configuration mode.
- They can be configured to filter traffic based on both source IP addresses and source ports.
- They can be created with a number but not with a name.
- They filter traffic based on source IP addresses only.
Explanation: A standard IPv4 ACL can filter traffic based on source IP addresses only. Unlike an extended ACL, it cannot filter traffic based on Layer 4 ports. However, both standard and extended ACLs can be identified with either a number or a name, and both are configured in global configuration mode.
