Question:
Refer to the exhibit. Which two ACLs would permit only the two LAN networks attached to R1 to access the network that connects to R2 G0/1 interface? (Choose two.)

• access-list 1 permit 192.168.10.0 0.0.0.127
• access-list 2 permit host 192.168.10.9
  access-list 2 permit host 192.168.10.69
• access-list 5 permit 192.168.10.0 0.0.0.63
  access-list 5 permit 192.168.10.64 0.0.0.63
• access-list 3 permit 192.168.10.128 0.0.0.63
  access-list 4 permit 192.168.10.0 0.0.0.255

Explanation: The permit 192.168.10.0 0.0.0.127 command ignores bit positions 1 through 7, which means that addresses 192.168.10.0 through 192.168.10.127 are allowed through. The two ACEs of permit 192.168.10.0 0.0.0.63 and permit 192.168.10.64 0.0.0.63 allow the same address range through the router.
