For the following options, which feature is the foundation of Cisco Self-Defending Network technology?

A.
policy management

B.
secure connectivity

C.
threat control and containment

D.
secure network platform

Explanation:
While all four answers have their merits, the Self-Defending Network model is concerned
with a secure network platform. Once the secure network foundation is established, the
other concerns can be addressed.
Incorrect:
A: A dynamic organizational policy allows efficiency when responding to attacks and
maintaining consistency of configuration when rolling out multiple devices.
B: Secure connectivity in an insecure network is a futile concept… taking care of the
secure network must occur first. IPsec and SSL VPNs can now be used to secure
remote-access.
C: Threat control can only occur once the foundation of a secure network is addressed.
Viruses and spyware, whether from internet sources or email, must be protected against to
keep servers and applications safe.
