You are the administrator at Certkiller Inc and you are implementing a small filtering router. As an alternative design in the SAFE SRM small network campus module, a small filtering router can be placed between the rest of the network and which devices?

A.
The rest of the network and Layer 2 switches

B.
The rest of the network and corporate users

C.
The rest of the network and management stations

D.
The rest of the network and routers

Explanation:

Alternatives
Setting a small filtering router or firewall between the management stations and the rest of the network can improve overall security. This setup will allow management traffic to flow only in the specific direction deemed necessary by the administrators. If the level of trust within the organization is high, HIDS can potentially be eliminated, though this is not recommended.
