Task 4 :- Make sure R1 Pc is communicated with R3 pc.
 From PC1

  
 -----------------------------------------------------------------------------------

 Task 5 :- block all trafic IT Department  to Sales Department.

If we Want to block Sales It means IT is Source and Sales is Destination and Standard will apply on destination

let's see
R3(config)#access-list 10 deny 192.168.1.0 0.0.0.255
R3(config)#
R3(config)#access-list 10 permit any
