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
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

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
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.
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.

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
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.

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?
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.

must also be evaluated. Security should be evaluated from the perspective that the external cloud provider must demonstrate security equal to or better than the internal IT organization. Risk should be evaluated and mitigated as part of the governance process before deploying applications or services in the cloud.
A company has asked for your assistance in mapping the act of service termination into their service design process. They have created a list of the key components in the termination process.
What factor is outside of this process?
- A . Ensuring user information remains private
- B . Agreement between parties to terminate the service
- C . De-provisioning the service instance SI
- D . Providing a chargeback or showback report SI
B
Explanation:
The termination process consists of four parts. De-provisioning the service instance, ensuring user information remains private, providing a chargeback or showback report, and feedback to improve the service. Depending on the terms and conditions, premature termination may incur penalties, such as the case when the service is contracted on a monthly basis and the instance is terminated by the user before the end of the billing cycle.
A bricks-and-mortar electronics retailer wants to increase sales by selling products through an online portal in addition stores. To achieve this, they have assembled a team of software developers to build the online portal and the selling capability.
Which cloud service model should they consider to quickly develop this solution?
- A . PaaS
- B . IaaS
- C . SaaS
- D . BaaS
A
Explanation:
• Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including network servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

What impact will these additional touch points have on the process?
- A . Increase in the number of APIs.
- B . Increase in service catalog deployments
- C . Delays in service delivery
- D . Delays in metric collection
C
Explanation:
For example, multiple touch points for a LOB often create delay in finalizing requirements and decision making, leading to delays in service delivery.
A service provider is preparing to offer PaaS. One of the challenges they are facing is incorporating the cost of databases.
What should you recommend as the best way to include this in the costing model?
- A . Treat database licensing as a variable cost in the model
- B . Treat database licensing as a fixed cost in the model
- C . Treat database licensing as a hybrid cost in the model
- D . Ignore database costs in the model
B
Explanation:
Two types of values can be used to associate cost with a particular service: fixed and variable.
Fixed costs are consumption-based and are typically associated with capital expenditures. Examples of fixed costs are compute, memory, storage, network, load balancers, firewalls, licensing , power, and cooling.
Variable costs identify administrative and operational activities to be performed and assigns a cost to each activity. These are typically indirect, or overhead, operational expenditures. Examples of variable costs include Full-Time Equivalents (FTE) for development, administration and server, storage and network administrators, cloud operators and administrators, developers, operators, and support engineers
What is the most important goal of an IT transformation to the cloud?
- A . IT operates more efficiently and at less cost
- B . IT should be more responsive and agile
- C . IT is aligned to business outcomes and demonstrates value
- D . IT should be a broker for external services
C
Explanation:
The operations department of a major hosting provider is under pressure to deliver services more quickly. They have a large number of tools for managing IT technologies across the data center. Although investments in virtualization and automation have been made, it still takes months to provision basic IT services to meet new customer demands.

You are designing a cloud services architecture for a company. You have determined that running some of the customer facing applications the company uses in a public cloud would save a significant amount of money but the security department wants to retain control of customer data at rest. The application infrastructure consists of two database servers and eight web servers.
How can you architect the application to minimize the risk involved with data exposure?
- A . Host the application servers in the public cloud and host the databases in the private cloud.
- B . Scale the application horizontally by utilizing a hybrid cloud where the application and database are mirrored a public cloud.
- C . Cluster four of the application servers and one database server in the public cloud and the remaining servers in the private cloud.
- D . Host the application servers and database servers in the public cloud and set up RBAC to restrict access to the applications
A company is considering transitioning to ITaaS. During an exploratory discussion, a potential stakeholder asks for clarification on the key difference(s) between traditional IT services and a cloud services.
What is the correct response?
- A . A traditional IT service is often provided without accounting for direct cost or business value to the lines of business; a cloud service is packaged to provide business value to the lines of business and support direct costing through showbacks.
- B . A traditional IT service views the physical network architecture as a manually-scaled system; a cloud service relies on an underlying layer of scalable network architecture.
- C . A cloud service is any service that uses one of the five tenets of cloud computing; a traditional IT service uses guidelines from a more traditional computing model.
- D . Both traditional IT services and cloud services are capable of driving value for the lines of business through service catalogs and degrees of automation; cloud services make use of cloud tenets and are designed to scale vertically.
A
Explanation:
Page 48 Manual.
As for cost, many traditional IT organizations look at cost from a high level but don’t have the ability to determine component costs. It’s easy to determine the costs of a server’s corresponding software, but new tools may be needed by IT organizations in order to break down costs at a component level, especially for offerings that come from shared environments. Many cloud service providers generate detailed invoices each month breaking down all the of the services used, how long, and their associated cost. Since one goal of ITaaS is to allow for IT to start behaving like an cloud service provider, determining how to break down costs by component is important.
An organization falls under the compliance regulations for PCI. The organization will deploy applications in the public cloud and wants to use a public cloud provider that is PCI compliant.

The CFO is discussing with you a chargeback model for critical qualities of service.
The model must allow for:
• Control of service usage over a short period of time (hours)
• Granular control of system load such as latency of applications
Which chargeback model should you recommend?
- A . Subscription by Peak Usage
- B . Electronic Ticket
- C . Pay-as-you-use no
- D . Bid/Spot Instance
B
Explanation:
Page 293 Manual.
Although not highlighted in the table, a ticket-based model may be employed in IT organizations with critical qualities of service. This model uses electronic tickets to control the service usage over a short period of time (hours), allowing a granular control of system load. Electronic tickets can be granted based upon the latency of the application. An example of this may be querying (granting a ticket) a database, but only when the load will not have an adverse impact on system performance.

A company wishes to transform to using cloud services. They have a good understanding of Service Oriented Architecture (SOA), but have not established the needed education, teamwork, and discipline to take them through the full ITaaS implementation.
As their cloud architect consultant, you need to take them to the next level in the service orientation maturity model.
What is the next level?
- A . Service Aligned
- B . Service Capable
- C . Service Aware
- D . Self-Service
You are responsible for building Service Level Agreements (SLAs) for your company. When building them for the service lifecycle of a cloud application, what should you consider?
- A . SLA updates may be needed due to the availability of new markets
- B . New SLAs should be created with the release of scheduled enhancements
- C . SLAs should incorporate all necessary requirements when they are created
- D . SLAs are contractual and cannot be changed without customer consent
B
Explanation:
Just as the creation of an application doesn’t imply that the application is complete and fulfills all needs, the creation of a service is an evolving process. The lifecycle is circular; the first release of a service may have important features, but updates will be made due to bugs, scheduled enhancements, requests for new features, performance improvements, and more.
A line of business has been using a public cloud provider and is now seeking services from the internal IT department. The line of business (LOB) has concerns about service performance and availability. They also want to have a clear and logical description of services, capabilities, and key performance indicators.
The organization would like to better understand support responsibilities and warranties.
What should the LOB obtain from the IT department to satisfy concerns?
- A . SLO
- B . Service offering
- C . Service template
- D . SLA
The principles of Autonomy, Abstraction, Discoverability, Composability, and Reusability are all principles of what?

An IT department is using a number of tools to automate the expansion and contraction of the cloud resource pools.
Which cloud feature are they implementing?
- A . Elasticity
- B . Monitoring
- C . Trust zones
- D . Chargeback
A
Explanation:
The orchestration engine is also the primary interface for service elasticity. If you allow consumers to provision virtual machines dynamically in order to absorb load changes, then they need to have access to the orchestration APIs to make this happen. The orchestration engine can again create and remove services as needed and trigger updates to CMDB and chargeback mechanisms.

- B . IT staff have to learn to focus only IT efficiently and costs
- C . Lines of business have to culturally change and only adopt IT’s service offering to prevent Shadow IT
- D . External service providers have to be retained to educate IT stuff on operating like one of them
An organization has been providing web services within their private cloud. The web services, deployed through a service catalog, depend on a database resource in the private cloud.
The organization decided to make these web services availability globally by using a public cloud provider.
However, once of the web services were deployed into the public cloud, users started complaining about poor performance.
Which solution would most likely improve performance of the web services.
- A . Balance the load globally across multiple instances of the database
- B . Re-architect the web-service to be deployed as a month coupled
- C . Re-architect the web-service to be loosely coupled with the database
- D . Balance the load globally across multiple instances of the web service.
D
Explanation:
Because things fail, it is important for cloud architects to design with the assumption that the underlying microservices infrastructure can and will fail.
However, when appropriately designed, nothing will really fail. The goal is applications that continue to function―even if the underlying physical hardware fails or is removed or replaced. One way to accomplish this goal is to avoid “single points of failure.” For example, having a distributed architecture supporting multiple instances, allows the infrastructure to reorganize service workloads as required .
An organization is using a hybrid cloud for services. Services are designed to use Load Balancers.
Orchestration workflows are designed so that services instances are placed in multiple fault domains.
Why are services designed in such a manner?
- A . Minimize impact of security breech
- B . Mitigate risk to service availability
- C . Mitigate risk to service integrity
- D . Minimize impact of governance policies

A European company has been providing web services within their private cloud. They now wish to make these web services available globally by using a public cloud provider. You are hired as a cloud architect to help them with this transition. In your analysis, you find that a different hypervisor is being used by the public cloud provider.
As the enterprise elastically provisions resources, what is a possible solution if the hypervisors are different?
- A . Modify the access role in the current service template to allow connection to the public cloud
- B . Recalibrate the current service template and deploy it in the public cloud
- C . Define a different service template to deploy in the public cloud
- D . Use a second service catalog to deploy the existing service template in the public cloud
C
Explanation:
Since the orchestration engine is really multiple layers of software working together to create a service, it is critical that all of the layers can talk to each other. Hypervisor integration is critical, but one should also consider that hypervisors may be different between the internal and public clouds. The service catalog orchestration component needs the ability to talk to different hypervisors. Otherwise, an intermediate step will need to be developed for translation or conversion with the other hypervisor. Automation of this intermediate step may require extra development. Similar situations may occur with integration with physical resources or other management processes like metering and chargeback.
