1) When PC0 sends a PING packet to PC1, do you think if the roundtrip packet across two offices is a symmetric transmission (i.e. in and out paths are same)? Briefly explain your answer.

2) How can you fix it if your above answer is negative? Or explain above if your answer is positive.

3.) Now you need to ensure 2Mbps link is the primary link for communication between PC0 and PC1 and 128kbps link is just a standby (for backup purpose). How can you configure floating static route(s) to achieve that?
