content dependencies on any resources in the private cloud. They are created from a standard
PaaS template, which includes an intrusion prevention system that periodically polls a central
management server for security updates. The IPS management server is located within the private
cloud. No layer 2 connectivity exists between the private and public clouds. The consumers of
these web services are distributed across the globe. Which solution would you recommend to best
support the web service elasticity and to minimize service network latency for the consumer?
A. Implement an encrypted VPN tunnel between the private and public clouds.
B. Implement a global load balancing service as a front-end for the web services.

were generated by the system. How did the enterprise protect its data?

keys were under complete control of the enterprise and were not available to the public
provider. The cloud provider’s logs showed that the enterprise’s services were copied.

encryption keys were secured by the public cloud provider in case they were lost. The cloud
provider’s logs showed that the enterprise’s services were neither accessed nor copied.
