Advantages of Using Static Routes on a Router: Improved Network Security and Reduced Resource Usage

Compared with dynamic routes, what are two advantages of using static routes on a router? (Choose two.) A)They automatically switch the path to the destination network when the topology changes. B)They Improve network security. C)They take less time to converge when the network topology changes. D)They use fewer router resources. E)They improve the efficiency of discovering neighboring networks.

Improved network security (Option B), Reduced router resources usage (Option D)

The two advantages of using static routes on a router, compared to dynamic routes, are:

1) Improved network security (Option B): Static routes provide greater control over the routing table. By manually configuring the routes, you have a better understanding of the network topology and can specifically define the path for the traffic. This reduces the possibility of unauthorized or malicious routing updates affecting network traffic. Static routes are less vulnerable to attacks like route poisoning and other malicious route manipulations.

2) Reduced router resources usage (Option D): Static routes consume fewer router resources compared to dynamic routes. This is because dynamic routing protocols require routers to exchange routing information, maintain neighbor relationships, and perform calculations to determine the best path for network traffic. In contrast, static routes do not involve any of these processes once they are manually configured. As a result, static routes require less CPU utilization, memory, and bandwidth, allowing routers to allocate those resources to other tasks.

Options A, C, and E are advantages of dynamic routes, not static routes.

A) Dynamic routes automatically switch the path to the destination network when the topology changes. This is a characteristic of dynamic routing protocols such as OSPF and EIGRP, not static routes.

C) Dynamic routes take less time to converge when the network topology changes. Dynamic routing protocols have mechanisms for fast convergence, adapting to topology changes by recalculating routes quickly. Static routes do not have this capability, as they need manual intervention to update routing information.

E) Dynamic routes improve the efficiency of discovering neighboring networks. Dynamic routing protocols use various mechanisms, such as hello messages and neighbor discovery algorithms, to discover and maintain neighbor relationships. This enables dynamic routes to efficiently learn about neighboring networks. Static routes, on the other hand, require manual configuration and do not include any neighbor discovery mechanism.
