Problem A:

You have been given the $192\mathrm{.}168\mathrm{.}20\mathrm{.}0/24$ network address to subnet, with the following topology.

Step $1$: Determine the number of subnets in Network Topology A$.$

Question $1$

$2$

Points

How many subnets are there?

Remember:

All LANs connected to Routers are to be counted as a subnet

Router$1($R$1)$ to Router$2($R$2)$ is to be counted as a subnet.

Router$2($R$2)$ to Router$3($R$3)$ is to be counted as a subnet.

Router$1($R$1)$to Router$3($R$3)$ is to be counted as a subnet.

Add your answer

Integer, decimal, or E notation allowed

Question $2$

$2$

Points

How many bits should you borrow to create the required number of subnets?

Add your answer

Integer, decimal, or E notation allowed

Question $3$

$3$

Points

How many usable host addresses per subnet are in this addressing scheme?

Note: Usable host addresses $=2($h$)-2$ where h is the number of host bits left in the new subnet mask

Add your answer

Integer, decimal, or E notation allowed

Question $4$

$2$

Points

What is the new subnet mask in dotted decimal format?

Note: Type full subnet mask

Add your answer

Dotted decimal

Binary

Original subnet mask $=255\mathrm{.}255\mathrm{.}255\mathrm{.}0$

$11111111111111111111111100000000$

New subnet mask $=???.???.???.???$

Question $5$

$2$

Points

What is the new CIDR notation for each new subnet? $($original network $=/24)$

Note: Just type number

Add your answer

Integer, decimal, or E notation allowed

Question $6$

$3$

Points

What is the increment between subnets?

Add your answer

Integer, decimal, or E notation allowed

Question $7$

$2$

Points

How many subnets are available for future use?

Add your answer

Integer, decimal, or E notation allowed

Step $2$: Record the subnet information.
