SCP Exam SC0-411 Topic 3 Question 50 Discussion

Your office branch has been assigned the network address of 10.10.0.0/16 by the Corporate HQ. Presently your network addressing scheme has these addresses split into eight networks as shown below:

1: 10.10.0.0/19

2: 10.10.32.0/19

3: 10.10.64.0/19

4: 10.10.96.0/19

5: 10.10.128.0/19

6: 10.10.160.0/19

7: 10.10.192.0/19

8: 10.10.224.0/19

You need to take the currently unused network block 10.10.160.0/19 and further divide it into four networks for use by a satellite branch that is being created on the top floor of your building. What will the new subnet mask be for these new networks?
