An engineer is working on a design solution for a large hub-and-spoke EIGRP network. Which feature helps to make this design more stable while also reducing resource utilization?

QoS manages traffic bandwidth and prioritization but does not influence EIGRP topology stability, query propagation, or routing table resource consumption.

Network summarization reduces routing table size and limits query scope somewhat, but it does not stop hub routers from querying spokes or prevent spokes from being used as transit paths.

When configured as EIGRP stubs, spoke routers advertise only their directly connected or summary routes and inform the hub that they should not receive EIGRP queries for other destinations, dramatically reducing the scope of the DUAL algorithm's query process and preventing stuck-in-active (SIA) conditions in large hub-and-spoke topologies.

Route filtering controls which prefixes are exchanged but does not suppress EIGRP queries or prevent spoke routers from participating in the DUAL process as transit nodes.
