Refer to the exhibit. Which command will advertise the 192.168.1.64/30 network but not the 192.168.1.32 network on router A?

To advertise only the 192.168.1.64/30 network (4 addresses: 64-65-66-67, with 64 network, 67 broadcast), the network command must specify the network address with a wildcard mask covering only that subnet. 0.0.0.3 in binary is 00000011, matching the last 2 bits. 192.168.1.64 with mask 0.0.0.3 matches 64, 65, 66, 67, exactly the /30 subnet. Using 0.0.0.7 would match 8 addresses (including the adjacent /29), and using 192.168.1.0 would advertise the entire /24 network.
