(b) Assume that the total of transmission, propagation and queueing delay for each message takes 0.2 seconds. Assume that the processing delay of a single DNS nameserver to respond to a DNS query takes 0.5 log(N) seconds, if the nameserver has N names in its database, where the log is base 10. Compare the time for a query and response for a complete DNS query and response (to all required nameservers) if M=1, M=2, and M=3.
