Cisco CCNA mock exam questions sample test – Question 230

.You are the network administrator for your company. The Chief Technical Officer of the company is looking for a routing solution that satisfies the following requirements:
No routing protocol advertisements
Increased network security
No routing protocol overhead
Not concerned about fault tolerance
Which of the following routing techniques matches the criteria?

A. Dynamic routing
B. Hybrid routing
C. Static routing
D. Public routing

Correct Answer: C

The static routing technique matches the criteria given in this scenario. Static routing is a process of manually entering routes into a routing table. Static routes are not recommended
for large networks because static routes are manually configured on the router. However, if a single link is used to connect an enterprise to an Internet Service Provider (ISP), then
static routing is the best option.
The following are characteristics of static routing:
Configuring static routes does not create any network traffic.
Manually configured static routes do not generate routing updates and therefore do not consume any network bandwidth.
Router resources are used more efficiently.
Static routes are not recommended for large networks because they are manually configured on the router and maintaining the routes can become problematic.
Static route configuration is not fault tolerant, because static routes do not automatically adapt to changes in the network.
The dynamic routing option is incorrect because route updates consume bandwidth and overhead. While the scenario is not concerned with routing protocol overhead, it states that
there should be no bandwidth consumption by route advertisements.
Hybrid routing and public routing are not valid routing techniques in Cisco terminology.
