• Question 131:

  Which of the following cloud migration methods would take full advantage of the cloud computing model?

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

  ---

  Explanation/Reference:

  Rip and replace is a cloud migration method that involves discarding the existing legacy system and building a new one from scratch on the cloud platform. This method allows the organization to take full advantage of the cloud computing model, such as scalability, elasticity, performance, and cost-efficiency. Rip and replace also enables the organization to leverage the cloud-native features and services, such as serverless computing, microservices, and containers. However, rip and replace is also the most complex and risky migration method, as it requires a complete redesign and redevelopment of the system, which can be time-consuming, expensive, and prone to errors. Therefore, rip and replace is only suitable for systems that are outdated, incompatible, or unsuitable for the cloud environment, and that have a clear business case and return on investment for the migration.

• Question 132:

  A company is required to move its human resources application to the cloud to reduce capital expenses. The IT team does a feasibility analysis and learns the application requires legacy infrastructure and cannot be moved to the cloud.

  Which of the following is the MOST appropriate cloud migration approach for the company?

  A. Lift and shift
  B. Hybrid
  C. Rip and replace
  D. In-place upgrade
  B. Hybrid

  ---

  Explanation/Reference:

  A hybrid cloud migration approach involves using a combination of on-premises and cloud resources to host an application. A hybrid cloud migration approach is suitable for applications that have dependencies or requirements that cannot be met by the cloud alone, such as legacy infrastructure, compliance, security, or performance1. A hybrid cloud migration approach can help reduce capital expenses by moving some components of the application to the cloud, while retaining others on-premises. A hybrid cloud migration approach can also provide flexibility, scalability, and resilience to the application, as it can leverage the best features of both environments2. A lift and shift cloud migration approach involves moving an application to the cloud as-is, without making any significant changes to its architecture or configuration. A lift and shift cloud migration approach is not appropriate for applications that require legacy infrastructure and cannot be moved to the cloud, as it would result in compatibility issues, performance degradation, or increased costs3. A rip and replace cloud migration approach involves discarding an application and replacing it with a new one that is designed for the cloud. A rip and replace cloud migration approach is not appropriate for applications that require legacy infrastructure and cannot be moved to the cloud, as it would result in loss of functionality, data, or customization, as well as increased complexity, risk, and cost4. An in-place upgrade cloud migration approach involves updating an application to a newer version that is compatible with the cloud, without changing its location or platform. An in- place upgrade cloud migration approach is not appropriate for applications that require legacy infrastructure and cannot be moved to the cloud, as it would not reduce capital expenses or provide any benefits of the cloud.

• Question 133:

  Which of the following cloud migration methods would be BEST suited for disaster recovery scenarios?

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

  ---

  Explanation/Reference:

  Lift and shift is a cloud migration method that involves moving an application or workload from one environment to another without making any significant changes to its architecture, configuration, or code. Lift and shift is also known as rehosting or forklifting. Lift and shift is best suited for disaster recovery scenarios because it allows for a fast and simple migration of applications or workloads to the cloud in case of a disaster or disruption in the original environment. Lift and shift can also reduce the risk of errors or compatibility issues during the migration process, as the application or workload remains unchanged. Lift and shift can also leverage the cloud's scalability, availability, and security features to improve the performance and resilience of the application or workload. However, lift and shift may not take full advantage of the cloud's native capabilities and services, and may incur higher operational costs due to the maintenance of the legacy infrastructure and software. Therefore, lift and shift may not be the best option for long-term or strategic cloud migration, but rather for short-term or tactical cloud migration for disaster recovery purposes. Replatforming, phased, and rip and replace are not the best cloud migration methods for disaster recovery scenarios, as they involve more changes and complexity to the application or workload, which may increase the migration time and risk. Replatforming is a cloud migration method that involves making some modifications to the application or workload to optimize it for the cloud environment, such as changing the operating system, database, or middleware. Replatforming is also known as replatforming or refactoring. Replatforming can improve the performance and efficiency of the application or workload in the cloud, but it may also introduce some challenges and costs, such as testing, debugging, and licensing. Phased is a cloud migration method that involves moving an application or workload to the cloud in stages or increments, rather than all at once. Phased is also known as iterative or hybrid. Phased can reduce the impact and risk of the migration process, as it allows for testing, feedback, and adjustment along the way. However, phased can also prolong the migration time and effort, as it requires more coordination and integration between the source and target environments. Rip and replace is a cloud migration method that involves discarding the existing application or workload and building a new one from scratch in the cloud, using cloud-native technologies and services. Rip and replace is also known as rebuild or cloud-native. Rip and replace can maximize the benefits and potential of the cloud, but it may also entail the highest cost and complexity, as it requires a complete redesign and redevelopment of the application or workload.

• Question 134:

  A network team establishes a new connection to an IaaS CSP that is more efficient and has networking costs that are 25% less than previous monthly expenditures. The bill outlines the following costs:

  Storage:$10000

  Compute:$12000

  Network:$7000

  Which of the following will be the total cloud expenditure for the following month?

  A. $26000
  B. $26250
  C. $27250
  D. $29000
  B. $26250

  ---

  Explanation/Reference:

  The total cloud expenditure for the following month can be calculated by adding the costs of storage, compute, and network. However, since the network team has established a new connection to an IaaS CSP that is more efficient and has networking costs that are 25% less than previous monthly expenditures, the network cost for the following month will be reduced by 25%. Therefore, the network cost for the following month will be $7000 x (1 - 0.25) = $5250. The total cloud expenditure for the following month will be $10000 + $12000 + $5250 = $26250.

• Question 135:

  Which of the following security objectives is MOST improved when moving a system to the cloud?

  A. Availability
  B. Integrity
  C. Privacy
  D. Confidentiality
  A. Availability

  ---

  Explanation/Reference:

  Availability is one of the security objectives that refers to the ability of authorized users to access and use the system and its resources when needed1. Availability is most improved when moving a system to the cloud, as cloud

  computing offers several benefits that enhance the reliability and accessibility of the system, such as23:

  Scalability: Cloud computing allows the system to dynamically adjust the amount of resources allocated to meet the changing demand, without affecting the performance or availability of the system.

  Redundancy: Cloud computing provides multiple copies of the system and its data across different locations and servers, ensuring that the system can continue to operate even if one or more components fail.

  Backup and recovery: Cloud computing enables the system to regularly backup the data and configuration to the cloud, and restore them quickly in case of a disaster or a failure.

  Maintenance and updates: Cloud computing allows the system to receive timely and automatic updates and patches from the cloud provider, without disrupting the availability of the system or requiring downtime. Service level agreements:

  Cloud computing offers service level agreements (SLAs) that guarantee a certain level of availability and uptime for the system, and provide compensation or remediation in case of a breach. References: 1:

• Question 136:

  A company is in its second year of a three-year agreement with a cloud vendor. After the initial phase of the cloud migration, resource consumption has stabilized.

  Which of the following would help the company reduce the cost of infrastructure?

  A. Reserved instances
  B. Pay-as-you-go
  C. Spot instances
  D. Bring your own license
  A. Reserved instances

  ---

  Explanation/Reference:

  Reserved instances are a type of cloud pricing model that allows customers to reserve a certain amount of cloud resources for a fixed period of time, usually one or three years, and pay a lower rate than the on-demand or pay-as-you-go model. Reserved instances are suitable for workloads that have predictable and stable resource consumption, as they can help customers save up to 75% of the cloud costs compared to the on-demand model1. However, reserved instances also require a long-term commitment and upfront payment, which may reduce the flexibility and scalability of the cloud. The other options are not likely to help the company reduce the cost of infrastructure: Pay-as-you-go: This is a type of cloud pricing model that allows customers to pay only for the resources they use, without any upfront or long-term commitment. Pay-as-you-go is suitable for workloads that have variable and unpredictable resource consumption, as it provides flexibility and scalability. However, pay-as- you-go is also the most expensive cloud pricing model, as it charges a higher rate per unit of resource than the reserved or spot instances models1. Spot instances: This is a type of cloud pricing model that allows customers to bid for unused cloud resources at a discounted rate, usually up to 90% lower than the on-demand model1. Spot instances are suitable for workloads that are flexible, interruptible, and not time-sensitive, as they can be terminated at any time by the cloud provider when the demand or price increases. Spot instances can help customers save a lot of money, but they also introduce a high level of uncertainty and risk to the cloud environment. Bring your own license: This is a type of cloud pricing model that allows customers to use their existing software licenses on the cloud, instead of purchasing new licenses from the cloud provider. Bring your own license can help customers reduce the software costs, but it does not affect the cost of infrastructure, which is based on the amount and type of cloud resources used2.

• Question 137:

  Which of the following BEST describes a pay-as-you-go licensing model within a cloud service?

  A. Subscription agreement
  B. Perpetual agreement
  C. Enterprise agreement
  D. Promotional agreement
  A. Subscription agreement

  ---

  Explanation/Reference:

  A subscription agreement is a type of pay-as-you-go licensing model within a cloud service, where the user pays a recurring fee for the access to the cloud resources and services. The fee is usually based on the number of users, the amount of data, or the duration of the subscription. A subscription agreement allows the user to scale up or down the cloud usage as needed, and only pay for what they use. A subscription agreement is different from a perpetual agreement, which is a one-time payment for a perpetual license to use the cloud service. A subscription agreement is also different from an enterprise agreement, which is a long-term contract that offers discounts and benefits for large-scale cloud usage. A promotional agreement is a temporary offer that provides free or discounted access to the cloud service for a limited time or under certain conditions.

• Question 138:

  A company's data center contract will expire in a few months, and the Chief Information Officer needs to move rapidly to a cloud environment. Which of the following is the BEST migration approach?

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

  ---

  Explanation/Reference:

  A lift and shift migration approach is the best option for a company that needs to move rapidly to a cloud environment. A lift and shift migration, also known as rehosting, involves moving an existing application and its associated data to a cloud platform without changing the app's architecture1. This approach is suitable for applications that are compatible with the cloud provider's infrastructure and do not require significant modifications or optimizations to run in the cloud2. A lift and shift migration can offer the following benefits for a company that needs to move quickly to the cloud34: Speed and simplicity: A lift and shift migration can be done faster and easier than other migration approaches that involve refactoring, replatforming, rebuilding, or replacing the application. A lift and shift migration can leverage automated tools and processes to reduce the manual effort and complexity involved in the migration. A lift and shift migration can also minimize the risk of errors, bugs, or compatibility issues that may arise from changing the application code or configuration. Cost savings: A lift and shift migration can help a company save costs by avoiding the expenses of maintaining or renewing the data center contract, hardware, software, or licenses. A lift and shift migration can also help a company take advantage of the pay-as-you-go pricing model and the scalability and elasticity features of the cloud, which can reduce the operational and capital expenditures. A lift and shift migration can also enable a company to benefit from the security, reliability, and performance enhancements offered by the cloud provider. Future flexibility: A lift and shift migration can help a company move to the cloud without disrupting the existing business operations or workflows. A lift and shift migration can also provide a foundation for future cloud optimization or modernization initiatives, such as refactoring, replatforming, rebuilding, or replacing the application to leverage the native cloud services and features. A lift and shift migration can also allow a company to adopt a hybrid or multicloud strategy, which can increase the availability, resilience, and agility of the application.

• Question 139:

  A company's current billing agreement is static. If the company were to migrate to an entirely IaaS-based setup, which of the following billing concepts would the company be adopting?

  A. Enterprise agreement
  B. Perpetual
  C. Variable cost
  D. Fixed cost
  C. Variable cost

  ---

  Explanation/Reference:

  Variable cost is a billing concept that means the customer pays only for the resources they consume, and the cost varies depending on the usage. This is different from fixed cost, which means the customer pays a predetermined amount regardless of the usage. IaaS-based setups typically use variable cost billing, as the customer can provision and deprovision resources on demand, and only pay for what they use. This allows the customer to optimize their costs and scale their resources according to their needs123.

• Question 140:

  When designing a new cloud-enabled application, an organization that is considering RTO and RPO is MOST likely concerned about:

  A. redundancy.
  B. load balancing.
  C. disaster recovery.
  D. high availability.
  C. disaster recovery.

  ---

  Explanation/Reference:

  Disaster recovery is the process of restoring the normal operations of an organization after a disruptive event, such as a natural disaster, a cyberattack, or a human error. Disaster recovery involves the planning, preparation, and implementation of strategies and procedures to minimize the impact and duration of the disruption, and to ensure the continuity and availability of the critical functions and data of the organization1 RTO and RPO are two key metrics that are used to measure and evaluate the disaster recovery capabilities and objectives of an organization. RTO stands for Recovery Time Objective, which is the maximum acceptable amount of time that an application or a service can be offline or unavailable after a disruption. RPO stands for Recovery Point Objective, which is the maximum acceptable amount of data that can be lost or unrecoverable after a disruption2 When designing a new cloud-enabled application, an organization that is considering RTO and RPO is most likely concerned about disaster recovery, as these metrics can help the organization to determine the optimal level of backup, redundancy, and recovery for the application, as well as the potential costs and risks of downtime or data loss. RTO and RPO can also help the organization to choose the appropriate cloud service model, provider, and deployment option that can meet the disaster recovery requirements and expectations of the organization and its customers3 References: CompTIA Cloud Essentials+ Certification Exam Objectives4, CompTIA Cloud Essentials+ Study Guide, Chapter 7: Cloud Security5, Cloud Essentials+ Certification Training
