What is the purpose of placing standard ACLs close to the destination?

The most appropriate reason for placing standard ACLs close to the destination relates to optimizing bandwidth usage. When standard ACLs are applied nearer to the destination, they can effectively block unnecessary traffic from traversing the network to the endpoint. By filtering out unwanted packets based on their source addresses before they reach the destination, the load on the network is reduced. This proactive filtering helps to conserve bandwidth, as fewer unnecessary packets consume the available network resources.

Choosing the correct placement for ACLs is crucial for network efficiency. If standard ACLs were placed far from the destination, potentially a significant volume of irrelevant traffic could consume bandwidth and processing power through various network segments before being filtered out, leading to congestion and decreased performance. Therefore, strategically positioning ACLs close to the destination enhances overall network performance and reliability by minimizing unnecessary traffic right at the source point of entry.
