Ok guys, I got this on a test about networking in the university. So lets assume ideal conditions for this one:
In Which communication schema the network is expected to have minimal latency in communication between PC1 and PC2
a) PC1 – Switch1 – Switch2 – Switch3 – PC2
b) PC1 – Firewall1 – Router – Firewall2 – PC2
c) PC1 – Router1 – Router2 – Router3 – PC2
d) PC1 – Switch1 – Router – Switch2 – PC2
I personnaly think that each message should travel though the 3 mid-nodes anyway and the less work on packets would make a difference between router and switch. The router's will speed up the connection in more complex environment when you have alternate paths and costs etc. Furthermore adding 3 routers will increase the traffic because the router's have internal protocols and will communicate between each other(RIP, OSPF ) In this simple case should the 3 switches be the fastest choice.
Thanks:)
