An office has 8 floors with approximately 30-40 users per floor.
One subnet must be used.
Which command must be configured on the router Switched Virtual Interface to use address space efficiently?
Click on the arrows to vote for the correct answer
A. B. C. D.B.
In a scenario where a single subnet must be used to serve users on different floors of a building, it is important to choose the correct subnet mask to ensure efficient use of the available address space.
Option A, which uses a subnet mask of 255.255.0.0, would create a very large subnet with over 65,000 host addresses. This is far more than necessary for a network with only 30-40 users per floor and would waste a significant amount of address space.
Option B, which uses a subnet mask of 255.255.254.0, would create subnets with 510 host addresses each. This is a reasonable number of addresses for a network with 30-40 users per floor, but it would require a significant amount of routing between floors.
Option C, which uses a subnet mask of 255.255.255.128, would create subnets with 126 host addresses each. This is a good compromise between the two previous options, providing enough addresses for the users on each floor without requiring excessive routing. This option would allow for up to 64 subnets, which should be sufficient for an office with 8 floors.
Option D, which uses a subnet mask of 255.255.255.224, would create subnets with only 30 host addresses each. This would be too small for the network described in the scenario, as it would not allow for growth or flexibility in the future.
Therefore, the correct answer is option C: ip address 192.168.0.0 255.255.255.128.
