Networking · Unit 2 · Paper 3

Network Infrastructure unit test

A test on this unit alone, marked as a percentage and a letter grade — for the test your class is actually sitting, rather than for May. Answer everything, then submit once: seeing the answer to question 3 before attempting question 4 makes the final percentage meaningless.

Paper 1 Paper 2 Paper 3

Each paper is built from this unit’s 40 terms and is the same for everyone, so a teacher can assign “Unit 2, Paper 3” and every student sits the identical test. Multiple choice is marked objectively; the written sections you mark yourself against the model answer and rubric.

A network administrator has been assigned the address block 192.168.10.0/24 and must divide it into four subnets, each supporting at least 50 hosts.

Determine the prefix length required and justify it.

State the subnet mask in dotted decimal notation.

Calculate the number of usable host addresses per subnet.

State the network address, first usable address, last usable address, and broadcast address of the SECOND subnet.

Explain why two addresses in each subnet cannot be assigned to hosts.

Explain what device is required for hosts in different subnets to communicate, and why a switch alone is not sufficient.
