Refer to the exhibit. Which command would be used in a standard ACL to allow only devices on the network attached to R2 G0/0 interface to access the networks attached to R1?

  1. access-list 1 permit 192.168.10.0 0.0.0.63
  2. access-list 1 permit 192.168.10.96 0.0.0.31*
  3. access-list 1 permit 192.168.10.0 0.0.0.255
  4. access-list 1 permit 192.168.10.128 0.0.0.63

Explanation: Standard access lists only filter on the source IP address. In the design, the packets would be coming from the 192.168.10.96/27 network (the R2 G0/0 network). The correct ACL is access-list 1 permit 192.168.10.96 0.0.0.31.
