Difference in Configuration Effort

Which statement best describes the difference in configuration effort between static and dynamic routing?

A Static routing requires manual setup for each route, while dynamic routing automatically adjusts routes based on network changes.

B Static routing automatically adjusts routes based on network changes, while dynamic routing requires manual setup.

C Both static and dynamic routing require manual setup for each route without automatic adjustments.

D Dynamic routing requires manual setup for each route, while static routing automatically adjusts routes based on network changes.

💡 Hint

Think about which routing type adapts to network changes without manual intervention.

Static routing needs manual configuration for every route and does not change unless manually updated. Dynamic routing protocols automatically discover and adjust routes as the network changes.

Routing Table Updates

How do static and dynamic routing differ in updating their routing tables?

A Both static and dynamic routing update routing tables automatically without manual changes.

B Static routing updates routing tables automatically; dynamic routing updates only when manually changed.

C Static routing updates routing tables only when manually changed; dynamic routing updates automatically through routing protocols.

D Neither static nor dynamic routing update routing tables automatically.

💡 Hint

Consider which routing type relies on protocols to learn about network changes.

Static routing tables remain fixed until manually changed by an administrator. Dynamic routing tables are updated automatically by routing protocols that share network information.

Suitability for Large Networks

Which routing method is generally more suitable for large, complex networks and why?

A Static routing, because it automatically discovers new routes without manual intervention.

B Dynamic routing, because it automatically adapts to network changes and scales better in large networks.

C Static routing, because it requires less processing power and is easier to manage in large networks.

D Dynamic routing, because it requires manual updates for each route, ensuring precise control.

💡 Hint

Think about how networks change and grow over time and which routing type handles that best.

Dynamic routing protocols automatically adjust to network topology changes, making them better suited for large and complex networks. Static routing is less flexible and requires manual updates, which is impractical at scale.

Impact on Network Traffic

How does static routing compare to dynamic routing in terms of network traffic generated for route maintenance?

A Dynamic routing generates no network traffic for route maintenance, while static routing sends updates regularly.

B Static routing generates more network traffic than dynamic routing because it sends frequent updates.

C Both static and dynamic routing generate the same amount of network traffic for route maintenance.

D Static routing generates no additional network traffic for route maintenance, while dynamic routing generates traffic to exchange routing information.

💡 Hint

Consider whether routing updates are sent automatically or only manually configured.

Static routing does not send routing updates over the network, so it generates no extra traffic. Dynamic routing protocols send periodic or triggered updates to maintain accurate routing tables, generating additional network traffic.

Choosing Routing Type for a Small Office Network

A small office network has a few routers and rarely changes its network layout. Which routing method is most appropriate and why?

A Static routing, because it is simple to configure and the network rarely changes, so manual updates are manageable.

B Dynamic routing, because it requires constant updates and is better for networks that rarely change.

C Dynamic routing, because it eliminates the need for any manual configuration regardless of network size.

D Static routing, because it automatically adapts to network changes without manual intervention.

💡 Hint

Think about the trade-off between configuration effort and network stability.

For small, stable networks, static routing is preferred because it is straightforward to set up and maintain. Dynamic routing adds unnecessary complexity and overhead in such environments.
