Assignment Gain skills required for the practical portion of the CCENT certification: The steps of the lab are contained in the Sample Solution. This particular lab does not require Cisco hardware to complete. Conditions You will find that the lab is most effective if you use it as a guide and work out your calculations on a separate sheet of paper. You can then check your work by clicking on the Hint button found in each step. Notes After taking a vLab for the first time using the Sample Solution, try the Suggested Approach link for a challenge. You've got a number of tools available on the left bar of the main page to aid you in your lab. Here are brief notes on each.

Task 1 – Computing Usable Subnets and Hosts

Step 1: You are given the Class C network address: 192.168.89.0. From this network, if you needed to create 2 subnets, how many bits would need to be borrowed at a minimum?

Action: Count on your fingers to work out how many bits need to be borrowed to create 2 subnets. Explanation: You can use this simple trick to determine the number of bits needed. Hold out your hand and counting on your fingers from left to right, the first finger equals 2, the second finger is double that (4), the third finger is doubled again (8), and so on. As an example, let’s say you needed 10 subnets. Count on your fingers until you reach the first number that is equal to or exceeds the value 10. Going from left to right that would be 2..4..8..16.. Stop. You needed four fingers to get to a number that was equal to or exceeds 10. Four is also how many bits that need to be borrowed to create 10 subnets. Using the same method, determine how many bits need to be borrowed to create 2 subnets. CREATING 2 SUBNETS = 1 bit To create 2 subnets, you will need to borrow at least one bit. Using your hand,
