Begin development of a self-service portal for the business to develop and deploy applications B. Attempt to consolidate vendors of hardware and software running in the environment by simplifying workloads C. Identify applications with workloads that run infrequently or that require boutique services for migration to the cloud D. Initiate a cloud comparison initiative to compare the price of competing cloud alternatives Answer: B Explanation: Page 97 Manual. Direct Efficiency • One way to quickly improve efficiency is to move from dedicated resource pools to a utility model in which provisioning is automated based on demand. Assess the environment for candidate applications to co-mingle across business lines that have complementary workloads. • Review the list of vendors hardware and software that is running. Determine if consolidation can occur based on simplifying the workloads into just the categories. Calculate a ratio of these in terms of workloads running. This is a good precursor for evaluating whether workloads are better suited to run in private or public cloud environments.

21. In the evolution of converged infrastructure, what are Appliances? A. Factory fabricated systems that offer a complete cloud with multiple personas on top of common hardware B. Multi-persona factory fabricated systems with integrated cloud deployment models that are able to scale storage and compute independently C. Engineered systems designed to deliver discreet components in a predictable manner with a single personality D. Single-personality infrastructure for customers that lack the expertise in-house to deploy and manage Converged Systems Answer: D Explanation: Correct Appliances offer a turnkey infrastructure and unparalleled simplicity for IT transformation. For customers that lack the expertise in house to deploy and manage converged systems, appliances offer a “simple-to-procure, deploy, and manage� option. As with blocks, appliances also are based on a single personality where a
customer can add a single cloud layer on these systems. This next category of Racks is where we start to look at application transformation. Racks come in two flavors: Turn-key cloud or application systems, which in addition to the hardware and hypervisor layers also offer a complete single cloud or application experience out of the factory, built to customer specifications and systems that offer the ability to support multiple personas on top of a common hardware platform. Customers can then add one or more cloud deployment models to deliver applications to fit their business and application needs. These systems provide the flexibility of not only multiple personas, but also the ability to scale storage independently of the compute
22.A company wants to deploy services in a new cloud infrastructure. A developer is helping the company design these services and has called upon a cloud automation engineer to help address some issues. What issues does the developer hope to address? A. Installation and configuration of the cloud orchestration server B. Orchestration and automation of the manual, legacy processes C. Orchestration and automation of the traditional development methods D. Design and configuration of the cloud orchestration server Answer: B
23.An organization wants to provide IaaS capabilities in a hybrid cloud. They have the following requirements: • Each line of business must have access to its own services and templates • Service templates should be as generic as possible • Data encryption should be provided for only services that require it • Each instance should use Microsoft Active Directory for authentication • Each instance should have the latest OS patches applied • Consumers should be given the ability to select which cloud to use for instance deployment How can these requirements be addressed in a cloud design? A. Add multiple pools and one template to the service catalog Provide orchestration workflows to create a tenant and then instantiate and customize instances Provide orchestration workflows to enable data encryption and authentication Enable a configuration manager policy for OS updates and pool placement B. Configure multiple tenants in the service catalog Add a single template to the service catalog Provide orchestration workflows to instantiate and customize instances Provide orchestration workflows to enable data encryption and authentication Enable a configuration manager policy for pool placement OS updates
C. Add multiple pools and one template to the service catalog Provide orchestration workflows to create a tenant and then instantiate and customize instances Provide orchestration workflows to enable data encryption and authentication Enable a configuration manager policy for OS updates D. Configure multiple tenants and pools in the service catalog Add a template to the service catalog for each tenant Provide orchestration workflows enabling instance creations, customization and placement Provide orchestration workflows enabling data encryption and authentication Enable a configuration manager policy for OS updates Answer: D
24.A cloud architect is helping a company with a new service design process. The architect notices that the company has a siloed, domain-centric IT organizational structure and is concerned about customer satisfaction. What impact would this type of structure have on customer satisfaction? A. Reduction in the supported number of tenants B. Delays with service authentication C. Decrease in service performance D. Delays in problem resolution Answer: D Explanation: Page 320 manual. Finally, a siloed domain-centric structure also causes delays in problem resolution since no one group has end to end visibility into a problem. This causes delay in problem resolution leading to drop in customer satisfaction. All of these factors contribute to service quality degradation. So, it is important that the organization is setup, from ground up, to deliver and support services.
25.Your customer's cloud applications are hosted by a CSP. You have been assigned to perform a compliance audit for the CSP's cloud architecture using the CSA framework. How can the company use the framework? A. Adopt the CSP's policies for security and their certifications B. Use the roles and responsibilities defined by the provider C. Determine what the service provider supplies for compliance requirements D. Measure the company's requirements for transparency in security policies Answer: C
26.An organization wants to use a public cloud provider for IaaS instances. They will develop and deploy their own applications within these instances. The organization must follow health care compliance regulations. What should the organization ensure before deploying their applications in the public cloud? A. Instances will not be placed in more than one availability zone B. Auditors have access to the cloud provider's data encryption keys C. Cloud provider supplies data-in-transit encryption capabilities D. Cloud provider supplies proper controls and audits for compliance requirements Answer: C Explanation: HIPAA is the U.S. law that regulates an individual’s healthcare information. HIPAA has two rules that we should focus on: • Privacy rule C requires that data is kept encrypted when in transit and at rest. • Security rule C requires that stringent controls are in place for access to data. It requires logging for audits (for example, who accesses what data and why). Additionally, backups require controls on the backup mediums and restoral procedures. Some cloud service providers have business associate agreements available with details on their websites.
27. DRAG DROP A company has an on-demand self-service portal. What is the most likely sequence of events in the service catalog when an IaaS service is provisioned?
Answer:
Explanation: On-demand self-service enables a consumer to request an IT service through a portal and for that service to be provisioned in a totally automated fashion. This is accomplished through a web-based catalog that lists available services and options. The service catalog is integrated with an orchestration mechanism, which uses predefined templates to provision services. In this example for a web server, the orchestration mechanism communicates with the hypervisor layer and triggers the creation of a service. CPU, RAM, and disk are allocated to the service, along with the proper network connection. The orchestration mechanism can also trigger the creation of other service options, like creating a backup schedule for a service, or provisioning metering and monitoring. The catalog and orchestration mechanism can also track the time that a service is made available and then what to do at lease expiration. Once the service is created, the consumer is alerted and can start consumption. 28.- Interacts with integrated orchestration mechanism 29.- Uses predefined templates to provision services 30.- Allocates resources and triggers creation of the service 31.- Provisions metering and monitoring
32. An organization is currently virtualized, and the CIO is planning for the transition to ItaaS. They are striving to make significant changes to internal IT processes and
policies in order to streamline operations, and to improve service levels by deploying automation and orchestration tools. What is the most important consideration when choosing the orchestration tool? A. Verify that the compute, storage and network element management tools can gather the required data for centralized management B. Allow the chargeback tool to integrate with external service provider infrastructure for unified cost charging C. Integrate with existing heterogeneous IT management tools including service desk, service catalog, performance monitoring and reporting D. Allow addition of more IT services to the service catalog to meet the business demands Answer: C
