Question of the Week 5

Question: What are the two major benefits that can be acheived by using a Hierarchical Network Addressing Scheme ?

A. Auto-negotiation of media rates. B. Efficient utilization of MAC addresses. C. Dedicated communications between devices. D. Reduces routing table entries. E. Ease of management and Troubleshooting.  

Answer to the Question

D and E

When we use hierarchical addresing scheme, it helps us to perform Route Summarization. Route summarization is a technique which can be used to reduce the size of the Routing Table. It is a technique that is used to group IP networks together to minimize advertisements.

It hides the details to simplify the routing process and it reduces router resource consumption (CPU and memory) required to store and process routes by reducing the number of routes.
