Figure $1$ Example of a Simple WAN

Question $1$: Refer to Figure $1,$ and suggest a suitable path between station A and station

E$.$

Question $2$: Refer to Figure $1,$ how many redundant paths are between node $4$ and node

$3?$

Question $3$: What is the difference between GE and FE ports?

Question $4$: Which ports do you prefer to use for the stations side and which ports do

you prefer to use for the WAN side?

Question $5$: Why did we select a subnet mask of $24$ bits for configuring the routers$-$to$-$

router links?

Question $6$: At this stage, you will need to verify the connectivity between Networks?

Question $7$: Now you have both PC$4\mathrm{.}1$ and PC $1\mathrm{.}1$ pinging at the same time PC$2\mathrm{.}1.$ What

are the common channels $($wires$)$ that these two ICMP messages are passing through?

Question $8$: Explain and reflect on how these two messages are being handled by the

packet$-$switched WAN network simultaneously
