Question

Which of the following summarized subnets represent routes that could have been created for CIDR’s goal to reduce the size of Internet routing tables?A. 10.0.0.0 255.255.255.0.

B. 10.1.0.0 255.255.0.0.
C. 200.1.1.0 255.255.255.0.
D. 200.1.0.0 255.255.0.0.

Answer 1

The answer is "Option D".

Step-by-step explanation:

This addressing arises in class C also with 255.255.255.0 subnets summarises with the 255.255.0.0 subnet. IP addressing the class. 10.0.0.0, is the part of the network class A, that port with a standard 255.0.0.0 subnet mask, and the address of 200.1.1.0 in Class C, which contains 255.255.255.0 classic subnet., and the wrong choice can be defined as follows:

• The choice a and choice b, it is incorrect because, the 10.0.0/24 a /24 is much more descriptive than a /8, the reverse of a description.

• The choice c, It does not summarise anything since 200.1.1.0 would be a Class C with such a classical 255.255.255.0 subset mask.
