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

1. A government department has converted their internal software development environment into a cloud services offering. The department is actively marketing the capability to other agencies. The other agencies are interested, but identity compliance is a serious concern.
How can the department improve trust within their service offering?

A) Provide a self-service portal that describes how the department's security policy is implemented. Require users to accept the policy each time it is amended.
B) Establish a single sign-on capability in the cloud and federate with each subscribing agency using strong authentication policies and end-point access control.
C) Identify the confidentiality, integrity and availability requirements for agency data. Use rights management software to restrict access to the agency's own data.
D) Harden the cloud service infrastructure stack. Use geographic location to ensure agencies can only access servers that host their development environment.

2. 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.
The web services have a loosely coupled design and have no 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 a global load balancing service as a front-end for the web services.
B) Deploy a central database server to consolidate web service content.
C) Increase bandwidth between the private cloud and the Internet.
D) Implement an encrypted VPN tunnel between the private and public clouds.

3. Refer to the exhibit.

A small insurance company wants to extend their website to the public cloud for elasticity and high availability. After reviewing the exhibit, what suggestion would you make to ensure expectations will be met?

A) Modify the application using DevOps to be cloud compliant
B) Upgrade the firewall to a newer version to support load balancing and QoS
C) Add a secondary DNS server to the enterprise data center
D) Add a web server to the public cloud to ensure proper balance

4. A hosting organization operates from two data centers and typically hosts very large customers. The delivery and support of the IT Infrastructure is not service driven. The IT technical delivery functions operate in silos. Customers suffer a significant lead time to establish new operational environments. In addition, changes to applications that impact the infrastructure have a long lead time.
One of the customers has requested a service-driven approach for a new business application and its associated infrastructure. The hosting organization has agreed to build a PaaS offering.
Which operational tool and process transformation approach is most suitable for the hosting company?

A) Deploy additional cloud tools alongside existing tooling. Train the IT operations teams to use the new tools. Start to transform operations once the cloud is up and running.
B) Design a new service-driven set of tools and processes. Train the IT operations teams to use the new tools. Manage cloud capacity using the existing process to order storage, network and compute.
C) Use the existing mature tools and processes that are used for all customers. Manage cloud capacity using the existing process to order storage, network and compute.
D) Design a new service-driven set of tools and processes. Train some of the IT operations teams to use the new tools. In advance of service demand, procure appropriate storage, network and compute capability for the cloud.

5. A public cloud service provider is facing several challenges in its IT operations:
1 - Rapidly increasing storage capacity needs, forcing frequent data migrations
2 - Transition to a converged network infrastructure with FCoE
3 - Deployment of several types of hypervisors simultaneously in production
4 - Long-term archival of very large volumes of tenant data for compliance
5 - In-flight encryption for tenants with stringent compliance requirements
Which challenge(s) would VPLEX address?
