What are three examples of dynamic IGPs?（）

单项选择题You have a network containing 120 routers. You must establish and maintain connectivity between the loopback interfaces of all routers. Because of the critical services using the network, you need redundancy and fast failover. Which routing protocol should you use in this scenario?（）

A. OSPF
B. RIP
C. BGP
D. static

单项选择题Which statement describes an advantage of dynamic routing?（）

A. Dynamic routing provides redundant IP addresses for end-user devices, unlike static routing.
B. Dynamic routing requires no initial user configuration, unlike static routing.
C. Dynamic routing provides DNS services along with IP connectivity; static routing does not.
D. Dynamic routing typically requires less time to implement than static routing in a large network.
