In which situation would a dynamic routing protocol be the quickest way to configure routes on a router?
Dynamic routing protocols are most beneficial in large networks because they automate the process of route discovery and maintenance. This automation significantly reduces the administrative burden compared to manually configuring static routes, especially as the number of routes increases. Large networks often experience frequent changes in network topology, and dynamic routing protocols can quickly adapt to these changes to ensure optimal path selection and minimize downtime.
A static routing protocol requires that routes be created and updated manually on a router or other network device. If a static route is down, traffic can’t be automatically rerouted unless an alternate route has been configured. Also, if the route is congested, traffic can’t be automatically rerouted over the less congested alternate route. Static routing is practical only in very small networks or for very limited, special-case routing scenarios (for example, a destination that’s used as a backup route or is reachable only via a single router). However, static routing has low bandwidth requirements (routing information isn’t broadcast across the network) and some built-in security (users can route only to destinations that are specified in statically defined routes).
The answer could be both a and d since both apply here but its asking specifically about which is quicker so I choose A.
Definitely A. D you would better achieve by creating static floating routes (with a lower AD) this is more CCNA knowledge but i think the same rules apply here.
Then again ... in a very large OSPF network consisting of multiple autonomous systems, you could "publish" a default route to all devices within 1 autonomous system by 'default-information originate' (again Cisco perspective here). I still think A is the primary answer but D could be a secondary...
Answer should be A Study Guide page 73 talks about differentiating between the two "Static routing is practical only in very small networks or for very limited, special-case routing scenarios (for example, a destination that’s used as a backup route or is reachable only via a single router). However, static routing has low bandwidth requirements..." Therefore the remaining answer A is correct for Dynamic Routing
The only possible answer is A. In most cases you will only be placing floating static routes as a backup.
A. Dynamic routing is considered easy to configure on large networks, and also, it is more intuitive than static routing at a selection of the best route, detection of the route changes, and also a discovery of the remote networks.
