Final answer:
Mesh topologies and star topologies are two good choices for highly available enterprise networks because they provide redundancy and fault tolerance, ensuring that the network remains operational even if some connections fail.
Step-by-step explanation:
Mesh topologies and star topologies are good choices for highly available enterprise networks. A mesh topology is a network setup where each device is connected to every other device on the network. This creates a robust and fault-tolerant system, as there are multiple paths for data to travel between devices. If one link fails, data can be rerouted through another path, thereby maintaining network availability. On the other hand, a star topology consists of a central hub or switch to which all network devices are connected. In this setup, each device has a dedicated connection to the hub, which acts as a central point for data transfer. This also contributes to high availability because even if one connection fails, it does not affect the others.
Both topologies offer their unique advantages for creating a network that ensures stability and continuity of operations. Businesses that require high availability and redundancy often incorporate these topologies into their enterprise networks to ensure that critical systems remain online even in the event of partial network failures.
