Expert Solution
Step 1: Introduction

As per our company guidelines only 3 sub parts will be answered. So, please repost the remaining questions separately.

All answers provided in the sheet are correct but i am providing explanation for first 3 questions only.

Subnetting is a process of dividng a single physical network into small logical sub networks which are called as subnets. It reduces the network traffic and also decreases the complexity of network.
