A finance team is writing down how spending on AWS differs in shape from spending on the company's own data center. Which statement matches the way AWS characterizes that difference?
ACharges are set from the capacity declared at the start of each month.
BCapital spent before use is replaced by charges that follow consumption.
CHardware is leased over a term and appears as a fixed cost each month.
DCosts are billed once a year against an amount committed in advance.
Show answer & explanation
B is correct. Task Statement 1.4 asks about the role of fixed costs compared with variable costs. 'Six advantages of cloud computing' opens with 'Trade fixed expense for variable expense - Instead of having to invest heavily in data centers and servers before you know how you're going to use them, you can pay only when you consume computing resources, and pay only for how much you consume.' Each distractor keeps the idea of a commitment or a fixed monthly figure, which is the shape of on-premises spending rather than the shape AWS describes.

A team proposes replacing a fleet of ageing instances with fewer, newer ones that do the same work on less hardware. Finance has already confirmed that the monthly bill will not fall, and the team must still file the proposal under one Well-Architected pillar. Which pillar covers it?
AReliability
BCost optimization
CSustainability
DPerformance efficiency
Show answer & explanation
C is correct. Task Statement 1.2 asks candidates to place work under the correct pillar. The Well-Architected Framework 'Sustainability' page states: 'The Sustainability pillar focuses on environmental impacts, especially energy consumption and efficiency, since they are important levers for architects to inform direct action to reduce resource usage.' Its design principles include 'Maximize utilization: Right-size workloads and implement efficient design to verify high utilization and maximize the energy efficiency of the underlying hardware' and 'Anticipate and adopt new, more efficient hardware and software offerings.' Removing the saving from the scenario is what separates this pillar from cost optimization.

The board of a manufacturer has approved a three-year change programme. Before any workload is picked, the CIO wants a published AWS method for judging how prepared the company itself is for what is coming, and for putting the stages of the programme into an order that reflects that. Which AWS resource is written for that?
AAWS Well-Architected Framework
BAWS Well-Architected Tool
CAWS Prescriptive Guidance
DAWS Cloud Adoption Framework
Show answer & explanation
D is correct. Task Statement 1.3 introduces AWS CAF. The whitepaper 'An Overview of the AWS Cloud Adoption Framework' states that you 'use the AWS CAF to identify and prioritize transformation opportunities, evaluate and improve your cloud readiness, and iteratively evolve your transformation roadmap'. The same page describes the AWS Well-Architected Framework as the material that 'helps you understand the pros and cons of the decisions you make when building systems in the cloud', whose six pillars cover 'designing and operating reliable, secure, efficient, cost-effective, and sustainable systems' - that is, one system at a time, which is the narrower scope every other option here shares.

A company is listing the costs it carries for its own data center so that it can compare them with the cost of running the same workloads on AWS. Which cost does it stop carrying directly once the workloads run on AWS?
ARacking, stacking and powering the servers, together with the facility that houses them.
BDeciding who in the company may access each system and keeping those permissions current.
CApplying updates to the operating systems that the company's own applications run on.
DTesting that the applications behave correctly after each change is released.
Show answer & explanation
A is correct. Task Statement 1.4 asks candidates to understand the costs associated with on-premises environments. 'Six advantages of cloud computing' in the AWS Overview whitepaper states 'Stop spending money running and maintaining data centers - Focus on projects that differentiate your business, not the infrastructure. Cloud computing lets you focus on your own customers, rather than on the heavy lifting of racking, stacking, and powering servers.' The three distractors are costs the AWS shared responsibility model leaves with the customer, so they survive the move.

An operations team builds an identical test environment by hand roughly twice a month, and small differences between environments regularly cause defects that cannot be reproduced. The team wants each environment to be created the same way every time and wants changes to the environment definition to be reviewable. What should the team adopt?
AA written runbook that lists each console step, kept under review by a second engineer before each build.
BA scheduled task that compares the two environments each night and reports the resources that differ.
CTemplates that describe the resources and their properties, and provision the environment as one unit.
DAn image of a fully configured instance that is copied each time a new environment has to be created.
Show answer & explanation
C is correct. Task Statement 1.4 asks candidates to identify the benefits of automation. The CloudFormation user guide states that you 'create a template that describes all the AWS resources that you want... and CloudFormation takes care of provisioning and configuring those resources for you,' that you can 'reuse your CloudFormation template to create your resources in a consistent and repeatable manner,' and that 'because these templates are text files, you simply track differences in your templates to track changes to your infrastructure.' The distractors keep the manual step, detect the problem late, or cover only a single server.
