CORRECT TEXT
SIMULATION
After recent changes to the pictured network, several users are unable to access the servers. Only PC1, PC2, PC3, and PC4 are configurable. You can only change
the adapter configurations to each PC.

Answer: See the explanation

Explanation:
On PC3, change the subnet mask to 255.255.255.0. When it is set to 255.255.255.128, then the PC with a .129 address will not be on the same subnet as the
default gateway which is .1
On PC4, change the default gateway to 10.0.2.1. It has been incorrectly set as 10.1.2.1.
On this simulation, you will be asked to test connectivity after fixing the issues. You MUST ping the other three computers on EACH computer (i.e. from PC1, ping
PC2, PC3, PC4, and from PC2, ping PC1, PC3 and PC4, etc)
