What is the default routing update period for RIPv2?

A.
15 seconds

B.
30 Seconds

C.
180 Seconds

D.
240 Seconds

Explanation:
The fact that RIP only records one route for each destination requires RIP to actively maintain the integrity of the routing tables, which can be achieved by asking all active RIP routers to broadcast contents of routing table to adjacent RIP routers in a fixed time interval. All received updated information automatically replaces the information included in the routing table.
RIP maintains routing table depending on three timers.
Update timer.
Routing-timeout timer.
Routing-refresh timer.
