Which is the most effective technique to contain EIGRP queries?

A.
route summarization

B.
configuring route filters

C.
using a hierarchical addressing scheme

D.
establishing separate autonomous systems

Explanation:
The most basic SIA routes occur when it simply takes too long for a query to reach the other end
of the network and for a reply to travel back. One of the most effective techniques for containing
EIGRP queries is to use route summarization or stub networks.
Stub networks are configured in a hub and spoke network and is configured only on the stub

router. The command is
router eigrp 100
eigrp stub
The result of this configuration is that the stub routers will send updates about routes they have to
the hub router but the hub router will never query the stub router for updates in the event of a route
being lost.
