Cisco CCNA 200-301 Practice Question

To block traffic from a specific source network to a specific destination network, an extended access control list (ACL) should be used because it can filter traffic based on both source and destination IP addresses. Applying the extended ACL close to the source network prevents unwanted traffic from traversing the network, conserving bandwidth and resources. Standard ACLs filter only on source IP addresses and cannot specify destination addresses, making them unsuitable for this task. Time-based ACLs add time conditions but are unnecessary here since there is no time-based requirement.
