2 – Request Security
3 – Respond Only
4 – No IPSec Policy
Your network hosts many servers, and different security policies are in place in different locations
in the network. The Clients and Servers in your network are configured as follows:
-You have servers numbered 1-9, which have a policy stating they require no network traffic security.
-You have servers numbered 10-19, which have a policy stating they are not required to be
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.
Based on the Client and Server configuration provided above, which of the following computers
must implement IPSec method 3?
