  1. Refer to the NAT configuration shown below. Match the address type with the correct address(es)?

    R1(config)#access-list 1 permit 192.168.10.0 0.0.0.255
    R1(config)#ip nat pool PATPOOL 209.165.2.34 209.165.2.35 overload
    R1(config)#interface fa0/0
    R1(config-if)#ip nat inside
    R1(config-if)#ip address 192.168.1.1 255.255.255.0
    R1(config)#interface serial 0/0/0
    R1(config-if)#ip address 209.165.2.33 255.255.255.240
    R1(config-if)#ip nat outside

    Address:
