Your network contains an Active Directory domain named contoso.com. The domain contains a
server named Server1 that runs Windows Server 2012 R2.
You create a new inbound rule by using Windows Firewall with Advanced Security.
You need to configure the rule to allow Server1 to accept unsolicited inbound packets that are
received through a network address translation (NAT) device on the network.
Which setting in the rule should you configure?

A.
Interface types

B.
Authorized computers

C.
Remote IP address

D.
Edge traversal

Explanation:
Edge traversal – This indicates whether edge traversal is enabled (Yes) or disabled (No). When edge
traversal is enabled, the application, service, or port to which the rule applies is globally addressable
and accessible from outside a network address translation (NAT) or edge device.
Select one of the following options from the list: Block edge traversal (default) – Prevent applications
from receiving unsolicited traffic from the Internet through a NAT edge device. Allow edge traversal
– Allow applications to receive unsolicited traffic directly from the Internet through a NAT edge
device. Defer to user – Let the user decide whether to allow unsolicited traffic from the Internet
through a NAT edge device when an application requests it. Defer to application – Let each
application determine whether to allow unsolicited traffic from the Internet through a NAT edge
device.
