22. Refer to the exhibit. The network is running the RIP routing protocol. Network 10.0.0.0 goes down. Which statement is true

regarding how the routers in this topology will respond to this event?

• Router4 will learn about the failed route 30 seconds later in the next periodic update.

• Split horizon will prevent Router4 from forwarding packets to the 10.0.0.0 network until the holddown timer expires.

• Router5 immediately flushes the unreachable route from its routing table.

• Router5 will send Router4 a triggered update with a metric of 16 for network 10.0.0.0.
