EMC IT-as-a-Service Expert Exam for Cloud Architects Sample Questions:

1. The marketing line of business of an enterprise has deployed web services within a private cloud. They wish to provide additional web services elastically and distribute them around the globe using a public cloud provider.

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) Increase bandwidth between the private cloud and the Internet.
C) Implement a global load balancing service as a front-end for the web services.
D) Deploy a central database server to consolidate web service content.
