A router has the following routing table (simplified): Router 1 Router 2 Router 3 Router 4 Which router would it send the IP address 192.168.1.156 to next? O Router 2 O Router 4 O Router 3 192.168.0.0/24 192.168.1.0/25 192.168.1.128/25 192.168.2.0/24 O Router 1 CIDR notation is the equivalent of putting that number of 1s at the beginning of the subnet mask. For example, /8 is the equivalent of 11111111 00000000 00000000 00000000. In other words, that this the equivalent of 255.0.0.0. A/16 would be the equivalent of 255.255.0.0. A/24 would be the equivalent of 255.255.255.0. What would equivalent to a /9 network mask? O 255.192.0.0 O 255.1.0.0 O 255.128.0.0 O 255.64.0.0
