Which are two characteristics of the stub feature in EIGRP ? (Choose two.)

• It stops the hub router from propagating dynamically learned EIGRP prefixes to the stub routers.
• It stops the hub router from sending queries to the stub router.
• It prevents routing loops by using the split-horizon rule.
• It stops the stub router from sending queries to IPv6 peers.
• It stops the stub router from propagating dynamically learned EIGRP prefixes to the hub routers.

Explanation: When using the EIGRP Stub Routing feature, you need to configure the distribution and remote routers to use EIGRP, and to configure only the remote router as a stub. Only specified routes are propagated from the remote (stub) router. The router responds to queries for summaries, connected routes, redistributed static routes, external routes, and internal routes with the message "inaccessible." A router that is configured as a stub will send a special peer information packet to all neighboring routers to report its status as a stub router.
Without the stub feature, even after the routes that are sent from the distribution router to the remote router have been filtered or summarized, a problem might occur. If a route is lost somewhere in the corporate network, EIGRP could send a query to the distribution router, which in turn will send a query to the remote router even if routes are being summarized. If there is a problem communicating over the WAN link between the distribution router and the remote router, an
EIGRP stuck in active (SIA) condition could occur and cause instability elsewhere in the network. The EIGRP Stub Routing feature allows a network administrator to prevent queries from being sent to the remote router.
