GIAC Information Security Fundamentals (GISF) — Question 1

You work as an Exchange Administrator for TechWorld Inc. The company has a Windows 2008 Active Directory-based network. The network contains an Exchange Server 2010 organization. The messaging organization contains one Hub Transport server, one Client Access server, and two Mailbox servers.
You are planning to deploy an Edge Transport server in your messaging organization to minimize the attack surface. At which of the following locations will you deploy the Edge Transport server?

Answer options

• A. Active Directory site
• B. Intranet
• C. Behind the inner firewall of an organization
• D. Perimeter network

Correct answer: D

Explanation

The correct location for the Edge Transport server is the Perimeter network, as it acts as a buffer between the internal network and the internet, thus minimizing the attack surface. Options A, B, and C are incorrect because they place the server within the internal network, which would not provide the same level of security and exposure control as the perimeter network.
