Which action should be taken when planning for redundancy on a hierarchical network design?
- add alternate physical paths for data to traverse the network
- continually purchase backup equipment for the network
- implement STP portfast between the switches on the network
- immediately replace a non-functioning module, service or device on a network
Explanation: One method of implementing redundancy is path redundancy, installing alternate physical paths for data to traverse the network. Redundant links in a switched network supports high availability and can be used for load balancing, reducing congestion on the network.
