Which two benefits are provided by using a hierarchical addressing network addressing scheme? (Choose two.)
Click on the arrows to vote for the correct answerA. B. C. D. E.
Here are some of the benefits of hierarchical addressing:
The correct answers to this question are A and E.
A hierarchical addressing network addressing scheme provides the following benefits:
A. Reduces routing table entries: By dividing the network into smaller subnets, a hierarchical addressing scheme reduces the size of the routing tables on routers. This is because each router only needs to maintain information about the networks that are directly connected to it and the networks that are one hop away. By using summarization, routers can represent multiple subnets as a single route, further reducing the size of the routing tables.
E. Ease of management and troubleshooting: A hierarchical addressing scheme makes it easier to manage and troubleshoot a network. Each subnet can be managed as a separate entity, and changes can be made to one subnet without affecting other subnets. Troubleshooting is also easier, as it is easier to isolate problems to specific subnets or devices.
B. Auto-negotiation of media rates: Auto-negotiation of media rates is a feature of Ethernet that allows two devices to automatically determine the best speed and duplex mode to use when communicating with each other. This feature is independent of the network addressing scheme and is not a benefit of using a hierarchical addressing scheme.
C. Efficient utilization of MAC addresses: MAC addresses are used to identify devices on a network. A hierarchical addressing scheme does not affect the efficiency of MAC address utilization. MAC addresses are assigned to devices by the manufacturer and are not related to the network addressing scheme.
D. Dedicated communications between devices: Dedicated communications between devices can be achieved using technologies such as point-to-point links, virtual private networks ( VPNs), or dedicated circuits. The network addressing scheme does not directly affect the ability to achieve dedicated communications between devices.
