Benefits of Hierarchical Addressing Network Addressing Scheme

AE

A hierarchical addressing network addressing scheme offers several benefits that make network management more efficient and easier to maintain. Here are the two benefits that are provided by using a hierarchical addressing network addressing scheme:

A. Reduces routing table entries: With a hierarchical addressing scheme, networks are organized into smaller, more manageable subnets. Each subnet can be assigned a unique network address that helps reduce the size of routing tables. By reducing the number of entries in routing tables, routers can process and forward packets more quickly, leading to better network performance.

E. Ease of management and troubleshooting: A hierarchical addressing scheme makes it easier to manage and troubleshoot networks. Each subnet can be assigned to a specific department, location, or function, making it easier to identify the source of network problems. Network administrators can also use hierarchical addressing to control access to network resources, ensuring that only authorized users can access critical data and applications.

B, C, and D are not benefits of using a hierarchical addressing scheme:

B. Auto-negotiation of media rates: Auto-negotiation of media rates is a feature of Ethernet that allows devices to automatically negotiate the speed and duplex mode of a network connection. While it can help ensure that devices are communicating at the same rate, it has nothing to do with a hierarchical addressing scheme.

C. Efficient utilization of MAC addresses: MAC addresses are used to identify network devices. While hierarchical addressing can help reduce the number of MAC addresses needed, it is not a primary benefit of a hierarchical addressing scheme.

D. Dedicated communications between devices: Dedicated communications between devices refers to a point-to-point connection between two devices, such as a leased line. While hierarchical addressing can help identify the source and destination of traffic, it does not provide dedicated communications between devices.
