secure, but will encrypt network traffic if the client is able to receive it.
-You have servers numbered 20-29, which have a policy stating they are required to be secure
and all network traffic they deliver must be secured.
-You have clients numbered 60-79 that are required to access secure servers 20-29.
-You have clients numbered 80-99 that are not required to access secure servers 20-29, but are
required to access servers 1-9 and 10-19.
