Cisco CCNA mock exam questions sample test – Question 81

.Which of the following is NOT an advantage of static routes over dynamic routing protocols?

A. Routing protocol overhead is not generated by the router.
B. Bandwidth is not consumed by route advertisements between network devices.
C. Static routes are easier to configure and troubleshoot than dynamic routing protocols.
D. Static route configuration is more fault tolerant than dynamic routing protocols.

Correct Answer: D

Explanation:
Static route configuration is NOT more fault tolerant than dynamic routing protocols. The following lists the true advantages of static routes over dynamic routing protocols:
Routing protocol overhead is not generated by the router.
Bandwidth is not consumed by route advertisements between network devices.
Static routes are easier to configure and troubleshoot than dynamic routing protocols.
Router resources are more efficiently used.
Network security is increased by using static routes.
The following are disadvantages of static routes:
Static routes are not recommended for large networks because static routes are manually configured on the router. Therefore, maintaining routes in a timely manner is nearly
impossible.
Static route configuration is not fault tolerant without configuring multiple static routes to each network with varying administrative distances.
All other options are incorrect because these are the advantages of static routes over dynamic routing protocols.
