  • A. A standard ACL statement that is configured on R1 is blocking the traffic sourced from Server1 network.
  • B. A standard ACL statement that is configured on R2 is blocking the traffic sourced from Server1 network.
  • C. A standard ACL statement that is configured on R2 is blocking the traffic sourced from R2 LAN network.
  • D. A standard ACL statement that is configured on R1 is blocking the traffic sourced from R2 LAN network.
Answer: Option B.
Explanation: 

We should check if we can ping from R1 to Server 1 or not:
The ping worked well so maybe R1 is good so we should check R2 first. We notice on R2 there is an access-list:

This access-list is applied to E0/2 interface with inbound direction. The purpose of this access-list is to block traffic with source IP address of 172.16.200.0/24 so it will block all traffic sent from Server 1 to us.
