Examine the black$-$hole situation in the dual$-$homed hub$-$and$-$spoke topology. When the hub A router loses connection to one of the spokes, the hub A router removes the spoke network $192\mathrm{.}168\mathrm{.}2\mathrm{.}0/24$ from the routing table, but the summary route $192\mathrm{.}168\mathrm{.}0\mathrm{.}0/22$ pointing to Null$0$ still exists as route summarization is done in both hub routers. So the incoming traffic that is destined for the spoke network $192\mathrm{.}168\mathrm{.}2\mathrm{.}0/24$ on the hub router A experiences traffic black holing.

Which two options would you use to solve this situation? $($Choose two.$)$

Interconnect two hub routers in the EIGRP domain, so that one of the hub routers still has a connection to the spoke. Then, the hub router that lost spoke connection can still receive the route information from the other hub router.

Do not summarize EIGRP routes between two hub routers.

Summarize the EIGRP routes from the hub to the spokes.

Inject a default route into the core to access the hubs.
