A company wants to avoid large upfront capital expenditures when launching new workloads. Which benefit of the AWS Cloud best addresses this requirement?
Trading fixed expense for variable expense means you pay only for what you consume instead of investing heavily in data centers before you know how much capacity you need. Economies of scale reduce per-unit cost but don't directly eliminate upfront capital. Speed/agility and capacity planning are separate benefits.
Under the AWS Shared Responsibility Model, which of the following is the customer's responsibility?
Customers are responsible for managing security group rules, which control inbound and outbound traffic to EC2 instances. AWS is responsible for the hypervisor, physical security of data centers, and the global network infrastructure.
Which TWO of the following are advantages of cloud computing as defined by AWS?
(Select TWO.)
Going global in minutes and benefiting from massive economies of scale are two of the six advantages of cloud computing listed by AWS. You still need IT staff (though in different roles), no service guarantees 100% uptime, and customers still share security responsibilities under the shared responsibility model.
A team wants to deploy the same infrastructure consistently across development, staging, and production environments. Which approach is best?
CloudFormation templates enable consistent, repeatable infrastructure deployment across environments. The same template ensures dev, staging, and production are identical. Manual configuration leads to drift and errors, and skipping environments is poor practice.
A company wants to run EC2 instances 24/7 for a three-year project with predictable resource needs. Which pricing model offers the greatest discount?
A 3-year Reserved Instance with All Upfront payment provides the greatest discount (up to 72% off On-Demand). Longer terms and upfront payments yield bigger discounts. On-Demand is full price, Spot is cheapest but interruptible and not suitable for 24/7 steady workloads, and a 1-year Savings Plan with No Upfront provides less discount.

Every detail of the test engine is designed to match the real CLF-C02 exam experience.
Each test draws a fresh subset from the 400-question bank. No two attempts are identical, so repeated practice exposes you to new questions rather than memorized patterns.
Questions are sampled in proportion to the official CLF-C02 domain weights: Cloud Concepts 24%, Security & Compliance 30%, Cloud Technology & Services 34%, Billing & Support 12%.
The A/B/C/D positions are reshuffled on every attempt, so you can't rely on position memory. The correct answer is always re-mapped to its new position before scoring.
Choose 15, 30, 45, or 65 questions. The 65-question test matches the real exam's 90-minute limit. A flag-for-review button lets you mark questions and return to them before submitting.
