Hi,

I am undertaking the NICF CCNA course at NTUC Learning Hub Pte Ltd in Singapore. In preparation for the internal mock exam, I have setup and configured the network using Cisco Packet Tracer as shown in the attachments here. I cannot ping the network from my PCs. Could you please help me look at the network, and the configuration of the switches and routers and tell me what's wrong?
