The task is to create an access list that allows traffic from a specific range of networks while logging the traffic. The networks in question span from 10.0.32.0/24 to 10.0.39.0/24. To summarize these networks into a single entry, we use a subnet mask that encompasses all the individual /24 networks. The correct summary uses the wildcard mask 0.0.7.255, which corresponds to the subnet mask 255.255.248.0. This wildcard mask allows for all addresses from 10.0.32.0 to 10.0.39.255, which includes all the specified networks.
