A. B. C. D. E. F.ABC
A. It uses consistent route determination:
Static routing uses a manually configured routing table to determine the path of packets between the source and destination. Once configured, the routing table remains constant until a manual update is made. Therefore, it provides consistent route determination.
B. It is best used for small-scale deployments:
Static routing is best suited for small-scale networks, where the routing table is simple and the network topology is stable. In larger networks, where the network topology is complex and frequently changing, static routing can become difficult to maintain and update.
C. Routing is disrupted when links fail:
One of the major disadvantages of static routing is that routing is disrupted when links fail. When a link fails, the routing table does not automatically update, and packets may be forwarded to a non-existent destination, causing network outages.
D. It requires more resources than other routing methods:
Static routing requires less overhead and resources than dynamic routing protocols, such as OSPF or EIGRP. However, it requires manual configuration of each router in the network, which can be time-consuming and prone to errors.
E. It is best used for large-scale deployments:
Static routing is not recommended for large-scale deployments because of the difficulty in maintaining the routing table as the network grows and changes. Dynamic routing protocols are better suited for large-scale networks as they provide automatic updates to the routing table.
F. Routers can use update messages to reroute when links fail:
This statement is not true for static routing. Static routes do not use update messages to reroute when links fail. Instead, administrators must manually update the routing table to reflect the changes in the network topology.
In summary, the three statements that are true about static routing are:
