  Explanation/Reference:

  Disaster recovery is the aspect of cloud design that enables a customer to continue doing business after a major data center incident. Disaster recovery is the process of restoring and resuming the normal operations of IT systems and services after a disaster, such as a natural calamity, a cyberattack, a power outage, or a human error1. Disaster recovery involves creating and storing backup copies of critical data and workloads in a secondary location or multiple locations, which are known as disaster recovery sites. A disaster recovery site can be a physical data center or a cloud-based platform2. Disaster recovery in cloud computing offers many advantages, such as34: Cost-effectiveness: Cloud disaster recovery eliminates the need to invest in and maintain expensive hardware, software, and facilities for the secondary site. Cloud disaster recovery also allows customers to pay only for the resources they use, and to scale up or down as needed. Reliability: Cloud disaster recovery ensures that the backup data and workloads are always available and accessible from any location and device. Cloud disaster recovery also leverages the security, performance, and redundancy features of the cloud provider to protect the data and workloads from corruption, loss, or theft. Flexibility: Cloud disaster recovery enables customers to choose from different cloud service models and deployment options, such as public, private, hybrid, or multicloud, depending on their business needs and preferences. Cloud disaster recovery also allows customers to customize and automate their recovery plans and policies, such as recovery point objective (RPO) and recovery time objective (RTO).

• Question 43:

  A business analyst asked for an RFI from a public CSP. The analyst wants to assess the financial aspects of a potential contract. Which of the following should the analyst expect to see in the RFI?

  A. Time to market
  B. Fixed costs
  C. Training
  D. Capital expenditures
  B. Fixed costs

  ---

  Explanation/Reference:

  A request for information (RFI) is a tool used by procurement teams to understand the options available for solving a problem or completing a task. Suppliers respond to RFIs with information about their products and services1. An RFI can inform buyers about the size, operation, experience, and products of potential suppliers2. A business analyst who asked for an RFI from a public cloud service provider (CSP) would want to assess the financial aspects of a potential contract. One of the financial aspects that the analyst should expect to see in the RFI is the fixed costs of the cloud service. Fixed costs are the costs that do not vary with the amount of resources or services consumed by the buyer. Fixed costs can include setup fees, subscription fees, maintenance fees, or support fees. Fixed costs can help the analyst to compare the prices of different cloud service providers and to plan the budget for the cloud project. Fixed costs can also affect the return on investment (ROI) and the total cost of ownership (TCO) of the cloud service3. The other options are not financial aspects that the analyst should expect to see in the RFI. Time to market, training, and capital expenditures are not relevant to the cloud service provider, but to the buyer. Time to market is the time it takes for the buyer to launch a product or service using the cloud. Training is the cost of educating the buyer's staff on how to use the cloud service. Capital expenditures are the costs of acquiring or upgrading physical assets, such as servers or hardware, for the cloud project. These are not information that the cloud service provider would provide in the RFI, but information that the buyer would need to consider in the procurement process.

• Question 44:

  A manufacturing company is selecting applications for a cloud migration. The company's main concern relates to the ERP system, which needs to receive data from multiple industrial systems to generate the executive reports. Which of the following will provide the details needed for the company's decision regarding the cloud migration?

  A. Standard operating procedures
  B. Feasibility studies
  C. Statement of work
  D. Benchmarks
  B. Feasibility studies

  ---

  Explanation/Reference:

  Feasibility studies are the best option to provide the details needed for the company's decision regarding the cloud migration. Feasibility studies are comprehensive assessments that evaluate the technical, financial, operational, and organizational aspects of moving an application or workload from one environment to another. Feasibility studies can help determine the suitability, viability, and benefits of migrating an application or workload to the cloud, as well as the challenges, risks, and costs involved. Feasibility studies can also help identify the best cloud solution and migration method for the application or workload, based on its requirements, dependencies, and characteristics. In the context of the manufacturing company, a feasibility study can help analyze the ERP system and its data sources, and provide information on how to migrate it to the cloud without compromising its functionality, performance, security, or compliance. A feasibility study can also help compare the cloud migration options with the current on-premises solution, and estimate the return on investment and the total cost of ownership of the cloud migration. Therefore, feasibility studies can provide the details needed for the company's decision regarding the cloud migration. Standard operating procedures, statement of work, and benchmarks are not the best options to provide the details needed for the company's decision regarding the cloud migration, as they have different purposes and scopes. Standard operating procedures are documents that describe the steps and tasks involved in performing a specific process or activity, such as installing, configuring, or troubleshooting an application or workload. Standard operating procedures can help ensure consistency, quality, and efficiency in the execution of a process or activity, but they do not provide information on the feasibility or suitability of migrating an application or workload to the cloud. Statement of work is a document that defines the scope, objectives, deliverables, and expectations of a project or contract, such as a cloud migration project or contract. Statement of work can help establish the roles, responsibilities, and expectations of the parties involved in a project or contract, but it does not provide information on the feasibility or viability of migrating an application or workload to the cloud. Benchmarks are tests or measurements that evaluate the performance, quality, or reliability of an application or workload, such as the speed, throughput, or availability of an application or workload. Benchmarks can help compare the performance, quality, or reliability of an application or workload across different environments, such as on-premises or cloud, but they do not provide information on the feasibility or benefits of migrating an application or workload to the cloud.

• Question 45:

  A company is migrating a legacy application to the cloud. Two C-level executives are currently engaged in the initial stages of the migration, and they are planning a rip-and- replace approach.

  Before initiating the project, the FIRST step should be to identify: (Choose Two)

  A. the required network performance.
  B. the key stakeholders.
  C. the desired CSP.
  D. the required cloud services.
  E. the required amount of storage.
  A. the required network performance.
  B. the key stakeholders.

  ---

  Explanation/Reference:

  Before initiating the project, the first step should be to identify the key stakeholders. The key stakeholders are the individuals or groups who have an interest or influence in the outcome of the project. They may include internal or external parties, such as executives, managers, employees, customers, suppliers, regulators, or partners1. Identifying the key stakeholders is important for several reasons, such as: Aligning the project goals and expectations: The key stakeholders can help to define the vision, scope, objectives, and requirements of the project. They can also provide feedback and approval throughout the project lifecycle. By involving the key stakeholders from the start, the project team can ensure that the project meets the needs and expectations of the stakeholders and delivers the desired value2. Securing the project resources and support: The key stakeholders can help to allocate the necessary resources and support for the project, such as budget, time, personnel, equipment, or data. They can also help to resolve any issues or conflicts that may arise during the project. By engaging the key stakeholders from the start, the project team can ensure that the project has the adequate resources and support to succeed3. Managing the project risks and changes: The key stakeholders can help to identify and mitigate the potential risks and changes that may affect the project, such as technical, operational, legal, or regulatory challenges. They can also help to communicate and implement the changes to the relevant parties. By collaborating with the key stakeholders from the start, the project team can ensure that the project adapts to the changing environment and minimizes the negative impacts4. The other options are not as suitable as identifying the key stakeholders for the first step of the project because: The required network performance: The required network performance is the level of quality and speed that the network needs to provide for the cloud application. The required network performance is an important factor to consider for the project, but it is not the first step. The required network performance depends on the type, size, and location of the cloud application, which are determined by the key stakeholders' input5. The desired CSP: The desired CSP is the cloud service provider that offers the cloud services and infrastructure for the cloud application. The desired CSP is an important factor to consider for the project, but it is not the first step. The desired CSP depends on the features, benefits, and pricing of the cloud services and infrastructure, which are evaluated by the key stakeholders' criteria. The required cloud services: The required cloud services are the cloud-based resources and capabilities that the cloud application needs to function. The required cloud services are an important factor to consider for the project, but they are not the first step. The required cloud services depend on the functionality, scalability, and security of the cloud application, which are defined by the key stakeholders' requirements. The required amount of storage: The required amount of storage is the amount of disk space that the cloud application needs to store its data. The required amount of storage is an important factor to consider for the project, but it is not the first step. The required amount of storage depends on the volume, variety, and velocity of the data, which are influenced by the key stakeholders' expectations. References:

• Question 46:

  An analyst is reviewing a report on a company's cloud resource usage. The analyst has noticed many of the cloud instances operate at a fraction of the full processing capacity. Which of the following actions should the analyst consider to lower costs and improve efficiency?

  A. Consolidating into fewer instances
  B. Using spot instances
  C. Right-sizing compute resource instances
  D. Negotiating better prices on the company's reserved instances
  C. Right-sizing compute resource instances

  ---

  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 47:

  A company is moving its long-term archive data to the cloud. Which of the following storage types will the company MOST likely use?

  A. File
  B. Object
  C. Tape
  D. Block
  B. Object

  ---

  Explanation/Reference:

  Object storage is a type of cloud storage that stores data as discrete units called objects. Each object has a unique identifier, metadata, and data. Object storage is ideal for storing long-term archive data in the cloud because it offers high scalability, durability, availability, and cost-effectiveness12. Object storage can handle large amounts of unstructured data, such as documents, images, videos, and backups, and allows users to access them from anywhere using a simple web interface3. Object storage also supports features such as encryption, versioning, lifecycle management, and replication to ensure the security and integrity of the archive data45.

• Question 48:

  Which of the following BEST explains the concept of RTOs for restoring servers to operational use?

  A. To reduce the amount of data loss that can occur in the event of a server failure
  B. To ensure the restored server is available and operational within a given window of time
  C. To ensure the data on the restored server is current within a given window of time
  D. To reduce the amount of time a particular server is unavailable and offline
  D. To reduce the amount of time a particular server is unavailable and offline

  ---

  Explanation/Reference:

  RTO stands for Recovery Time Objective, which is a metric that measures the maximum acceptable amount of time that an application or a service can be offline or unavailable after a disruption, such as a server failure, a power outage, or a natural disaster. RTO is a key indicator of the disaster recovery capabilities and objectives of an organization, as it reflects the level of tolerance or impact of downtime on the business operations, reputation, and revenue. RTO is usually expressed in hours, minutes, or seconds, and it can vary depending on the criticality and priority of the application or the service. RTO can help an organization to determine the optimal level of backup, redundancy, and recovery for the application or the service, as well as the potential costs and risks of downtime. RTO 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 customers12 Therefore, the best explanation of the concept of RTOs for restoring servers to operational use is to reduce the amount of time a particular server is unavailable and offline, as this implies the goal of minimizing the duration and frequency of downtime, and restoring the normal operations and functionality of the server as quickly as possible.

• Question 49:

  A business analyst is writing a disaster recovery strategy. Which of the following should the analyst include in the document? (Select THREE).

  A. Capacity on demand
  B. Backups
  C. Resource tagging
  D. Replication
  E. Elasticity
  F. Automation
  G. Geo-redundancy
  H. Autoscaling
  B. Backups
  D. Replication
  G. Geo-redundancy

  ---

  Explanation/Reference:

  A disaster recovery strategy is a plan that defines how an organization can recover its data, systems, and operations in the event of a disaster, such as a natural calamity, a cyberattack, or a human error. A disaster recovery strategy should include the following elements12: Backups: Backups are copies of data and files that are stored in a separate location from the original source. Backups help to restore the data in case of loss, corruption, or deletion. Backups can be performed manually or automatically, and can be stored on-premises, off-site, or in the cloud. Backups should be encrypted, secured, and tested regularly to ensure their integrity and availability3. Replication: Replication is the process of copying and synchronizing data and systems across multiple locations or platforms. Replication helps to maintain the consistency and availability of the data and systems in case of a failure or outage. Replication can be done at different levels, such as storage, database, application, or virtual machine. Replication can be synchronous or asynchronous, depending on the latency and bandwidth requirements4. Geo-redundancy: Geo-redundancy is a feature that allows the distribution and replication of data and systems across multiple geographic regions or zones. Geo- redundancy helps to ensure the resiliency and continuity of the data and systems in case of a regional disaster or disruption. Geo-redundancy can also improve the performance and latency of the data and systems by serving the requests from the nearest location. Geo-redundancy can be achieved by using cloud services that offer multi-region or multi-zone capabilities5 .

• Question 50:

  An organization wants to migrate a locally hosted application to a PaaS model. The application currently runs on a 15-year-old operating system and cannot be upgraded.

  Which of the following should the organization perform to ensure the application will be supported in the cloud?

  A. Risk register
  B. Feasibility study
  C. Benchmarks
  D. Baseline
  B. Feasibility study

  ---

  Explanation/Reference:

  A feasibility study is a process of evaluating the viability of a project or an idea before committing resources and time to it. It helps to identify the potential benefits, costs, risks, and challenges of a proposed solution. A feasibility study is especially important when migrating an application to a cloud platform, as it can determine whether the application is compatible with the cloud provider's services, standards, and requirements. In this case, the organization wants to migrate a locally hosted application that runs on a 15-year-old operating system to a PaaS model. The application cannot be upgraded, which means it may not be supported by the cloud provider's platform. A feasibility study can help the organization to assess the technical and operational feasibility of the migration, as well as the financial and strategic implications. A feasibility study can also help the organization to compare different cloud providers and select the best one for their needs.
