A company plans to modernize a monolithic application into microservices that use serverless components, accepting the highest effort and cost in exchange for the greatest long-term agility. Which migration strategy is this?
Intermediate · Choose one
Explanation
Answer: C. Refactor, also called re-architect, means moving the application to the cloud and modifying its architecture to take full advantage of cloud-native features in order to improve agility, performance, and scalability. AWS notes it is the most complex strategy and generally recommends rehosting, relocating, or replatforming first in a large migration, then modernizing afterwards.
A. Relocate transfers servers or applications to a cloud version of the existing platform, or moves instances between VPCs, Regions, or accounts, without changing the architecture.
B. Retain leaves the application in the source environment, so no modernization occurs at all.
D. Rehost moves the application unchanged, which is the opposite of the significant redesign described here.

An application is subject to a contract that prevents any change to its hosting arrangements for another 18 months. Which migration strategy should be recorded for it during portfolio planning?
Intermediate · Choose one
Explanation
Answer: A. Retain means keeping the application in its source environment or postponing its migration because the organization is not ready to move it. Recording it explicitly matters: it documents the reason, sets a review date, and keeps the application visible in the portfolio rather than forgotten.
B. Relocate would also move it, and it applies to transferring servers to a cloud version of the existing platform, which is still a change to the hosting arrangement.
C. Retire is for applications that are no longer needed and can be decommissioned or archived. This application is still in use and under contract.
D. Rehost would move it now, which the contract forbids.

Which AWS CAF perspective is concerned with culture evolution, cloud fluency, workforce transformation, and change acceleration?
Intermediate · Choose one
Explanation
Answer: B. The people perspective serves as the bridge between technology and business, addressing culture, organizational structure, leadership, and workforce. Its capabilities include culture evolution, transformational leadership, cloud fluency, workforce transformation, change acceleration, organization design, and organizational alignment.
A. The governance perspective orchestrates cloud initiatives while maximizing benefits and minimizing transformation risk, covering capabilities such as program and project management, risk management, and cloud financial management.
C. The operations perspective ensures that cloud services are delivered at a level that meets business needs, covering observability, incident and problem management, and availability and continuity management.
D. The business perspective ensures that cloud investments accelerate digital transformation ambitions and business outcomes, covering strategy, portfolio, innovation, and product management.

Under the AWS Cloud Adoption Framework, which perspective owns the cloud financial management capability?
Intermediate · Choose one
Explanation
Answer: B. Cloud financial management, described as planning, measuring, and optimizing cloud spend, sits in the governance perspective. Governance is where the organization orchestrates cloud initiatives and controls risk and value, alongside capabilities such as program and project management, benefits management, risk management, application portfolio management, and data governance.
A. The platform perspective builds the enterprise-grade cloud platform, covering platform and data architecture, platform and data engineering, provisioning and orchestration, modern application development, and continuous integration and delivery.
C. The operations perspective runs the services day to day, covering observability, event management, incident and problem management, change and release management, and patch management.
D. The business perspective is about aligning cloud investment with business outcomes through capabilities such as strategy management, portfolio management, innovation management, and product management. It sets direction rather than managing the spend itself.

Which set correctly lists the four AWS CAF transformation domains?
Intermediate · Choose one
Explanation
Answer: D. AWS CAF names four transformation domains. Technology covers migrating and modernizing infrastructure, applications, and data platforms. Process covers digitizing, automating, and optimizing business operations. Organization covers reimagining the operating model so business and technology teams create customer value together. Product covers reimagining the business model with new value propositions and revenue models.
A. These are four of the seven migration strategies. They describe how an individual application moves, not enterprise transformation domains.
B. These are four of the six AWS CAF perspectives, which group the foundational capabilities that support transformation, rather than the domains being transformed.
C. Envision, align, launch, and scale are the four phases of the cloud transformation journey, which describe when work happens rather than what is transformed.
