• Question 11:

  A company decides to move some of its computing resources to a public cloud provider but keep the rest in-house. Which of the following cloud migration approaches does this BEST describe?

  A. Rip and replace
  B. Hybrid
  C. Phased
  D. Lift and shift
  B. Hybrid

  ---

  Explanation/Reference:

  A hybrid cloud migration approach best describes the scenario where a company decides to move some of its computing resources to a public cloud provider but keep the rest in-house. A hybrid cloud is a type of cloud deployment that combines public and private cloud resources, allowing data and applications to move between them. A hybrid cloud can offer the benefits of both cloud models, such as scalability, cost-efficiency, security, and control. A hybrid cloud migration approach can help a company to leverage the advantages of the public cloud for some workloads, while maintaining the on-premise infrastructure for others. For example, a company may choose to migrate its web applications to the public cloud to improve performance and availability, while keeping its sensitive data and legacy systems in the private cloud for compliance and compatibility reasons. A hybrid cloud migration approach can also enable a gradual transition to the cloud, by allowing the company to move workloads at its own pace and test the cloud environment before fully committing to it.

  Explanation/Reference:

  Right-sizing compute resource instances is the process of matching instance types and sizes to workload performance and capacity requirements at the lowest possible cost. It's also the process of identifying opportunities to eliminate or downsize instances without compromising capacity or other requirements, which results in lower costs and higher efficiency1. Right-sizing is a key mechanism for optimizing cloud costs, but it is often ignored or delayed by organizations when they first move to the cloud. They lift and shift their environments and expect to right-size later. Speed and performance are often prioritized over cost, which results in oversized instances and a lot of wasted spend on unused resources2. Right-sizing compute resource instances is the best action that the analyst should consider to lower costs and improve efficiency, as it can help reduce the amount of resources and money spent on instances that operate at a fraction of the full processing capacity. Right- sizing can also improve the performance and reliability of the instances by ensuring that they have enough resources to meet the workload demands. Right-sizing is an ongoing process that requires continuous monitoring and analysis of the instance usage and performance metrics, as well as the use of tools and frameworks that can simplify and automate the right-sizing decisions1.

  Consolidating into fewer instances, using spot instances, or negotiating better prices on the company's reserved instances are not the best actions that the analyst should consider to lower costs and improve efficiency, as they have some limitations and trade-offs compared to right-sizing. Consolidating into fewer instances can reduce the number of instances, but it does not necessarily optimize the type and size of the instances. Consolidating can also introduce performance and availability issues, such as increased latency, reduced redundancy, or single points of failure3. Using spot instances can reduce the cost of instances, but it also introduces the risk of interruption and termination, as spot instances are subject to fluctuating prices and availability based on the supply and demand of the cloud provider4. Negotiating better prices on the company's reserved instances can reduce the cost of instances, but it also requires a long-term commitment and upfront payment, which reduces the flexibility and scalability of the cloud environment5.

• Question 13:

  A cloud risk assessment indicated possible outages in some regions. In response, the company enabled geo- redundancy for its cloud environment. Which of the following did the company adopt?

  A. Risk mitigation
  B. Risk acceptance
  C. Risk transference
  D. Risk avoidance
  A. Risk mitigation

  ---

  Explanation/Reference:

  Risk mitigation is the process of reducing the impact or likelihood of a risk by implementing controls or countermeasures. By enabling geo-redundancy for its cloud environment, the company adopted a risk mitigation strategy to minimize the effect of possible outages in some regions. Geo-redundancy is a feature that allows the replication and distribution of data and services across multiple geographic locations to ensure availability and resiliency12. If one region experiences an outage, the company can still access its data and services from another region.

• Question 14:

  Which of the following risks can an organization transfer by adopting the cloud?

  A. Data breach due to a break-in at the facility
  B. Data sovereignty due to geo-redundancy
  C. Data loss due to incomplete backup sets
  D. Data misclassification due to human error
  A. Data breach due to a break-in at the facility

  ---

  Explanation/Reference:

  One of the risks that an organization can transfer by adopting the cloud is data breach due to a break-in at the facility. This is because the cloud service provider (CSP) is responsible for the physical security of the data center where the data is stored and processed. The CSP should have adequate measures to prevent unauthorized access, theft, or damage to the hardware and infrastructure. By outsourcing the data storage and processing to the CSP, the organization transfers the risk of physical breach to the CSP. However, the organization still retains the risk of data breach due to other factors, such as network attacks, misconfiguration, or human error. Therefore, the organization should also implement appropriate controls to protect the data in transit and at rest, such as encryption, authentication, and monitoring.

• Question 15:

  A vendor wants to distribute a cloud management application in a format that can be used on both public and private clouds, but one that does not include an underlying OS that would require patching and management. Which of the following would BEST meet this need?

  A. Containerization
  B. Federation
  C. Collaboration
  D. Microservices
  A. Containerization

  ---

  Explanation/Reference:

  Containerization is a software deployment process that bundles an application's code with all the files and libraries it needs to run on any infrastructure. Containerization does not include an underlying operating system that would require patching and management, as containers share the host operating system kernel and run in isolated user spaces. Containerization allows applications to run consistently and portably on any platform or cloud, regardless of the differences in operating systems, hardware, or configurations. Containerization also enables faster and easier deployment, scalability, and fault tolerance of applications. Therefore, containerization would best meet the need of a vendor who wants to distribute a cloud management application in a format that can be used on both public and private clouds. The other options are not relevant to the question. Federation is a process of integrating multiple cloud services or providers to create a unified cloud environment. Collaboration is a process of working together on a shared project or goal using cloud-based tools and platforms. Microservices are a software architecture style that breaks down a complex application into smaller, independent, and loosely coupled services that communicate through APIs. Microservices can be implemented using containers, but they are not a software deployment format. Therefore, the correct answer is A. Containerization.

  A. A company specializing in application development
  B. A company with many legacy applications
  C. A company with proprietary systems
  D. A company that outsources support of its IT systems
  A. A company specializing in application development

• Question 17:

  A company has a perpetual license for a database application. Which of the following is the MOST cost- effective option when moving to the cloud?

  A. Fixed
  B. Subscription
  C. EULA
  D. BYOL
  D. BYOL

  ---

  Explanation/Reference:

  BYOL stands for Bring Your Own License, which is a cloud service model that allows customers to use their existing software licenses when migrating to the cloud. BYOL can help customers to reduce costs, avoid vendor lock-in, and leverage their existing investments in software. BYOL is the most cost-effective option when moving to the cloud for a company that has a perpetual license for a database application, as it does not require paying additional fees for the cloud provider's license or subscription. However, BYOL may have some limitations, such as compatibility, compliance, or support issues, depending on the cloud provider and the software vendor. Therefore, customers should carefully review the terms and conditions of their licenses and the cloud provider's policies before choosing BYOL.

• Question 18:

  Transferring all of a customer's on-premises data and virtual machines to an appliance, and then shipping it to a cloud provider is a technique used in a:

  A. phased migration approach.
  B. replatforming migration approach.
  C. rip and replace migration approach.
  D. lift and shift migration approach.
  D. lift and shift migration approach.

  ---

  Explanation/Reference:

  A lift and shift migration approach, also known as rehosting, is a cloud migration strategy where applications and infrastructure are moved from one environment to another without making substantial changes to the underlying architecture123. This approach can be faster, cheaper, and less risky than other migration strategies, as it does not require extensive redesign or reconfiguration of the applications. However, it may also limit the ability to leverage the native features and benefits of the cloud platform, such as scalability, elasticity, and performance1245. One of the challenges of a lift and shift migration is transferring large amounts of data and virtual machines over the network, which can be time-consuming, costly, and prone to errors. To overcome this challenge, some cloud providers offer a technique where the customer can transfer all of their on-premises data and virtual machines to an appliance, such as a physical storage device or a server, and then ship it to the cloud provider. The cloud provider then uploads the data and virtual machines to the cloud platform, where they can be accessed by the customer12. This technique can reduce the network bandwidth and latency issues, as well as the security risks, associated with transferring data over the internet. However, it may also introduce additional costs and delays for shipping and handling the appliance, as well as the risk of damage or loss during transit2. Therefore, transferring all of a customer's on-premises data and virtual machines to an appliance, and then shipping it to a cloud provider is a technique used in a lift and shift migration approach.
