Amazon Web Services Updated CLF-C02 Exam Questions and Answers by rogan

Spot Instances offer the lowest cost for Amazon EC2 and are suitable for non-production workloads like development and testing where occasional unavailability is acceptable. Spot Instances take advantage of unused EC2 capacity at a reduced cost, making them ideal for environments that can tolerate interruptions. Reserved or On-Demand Instances would be more expensive for this scenario, and Dedicated Hosts are not cost-effective for non-production environments.

Comprehensive and Detailed Explanation From AWS Cloud Documentation:

The AWS Cloud Adoption Framework Operations perspective focuses on delivering cloud services at an agreed level and improving workload reliability through effective operations. AWS lists observability as an Operations capability because teams need metrics, logs, traces, endpoint monitoring, and alerts to understand workload health and identify problems. AWS also lists configuration management as an Operations capability because organizations need an accurate record of workloads, relationships, settings, and configuration changes, and must control configuration drift. Therefore, options A and E are correct. The other choices belong to different AWS CAF perspectives. Data governance is a Governance perspective capability concerned with authority, ownership, standards, quality, and control over organizational data. Platform architecture is a Platform perspective capability that establishes architectural guidelines, patterns, principles, and guardrails for the cloud environment. Portfolio management is a Business perspective capability that prioritizes cloud products and initiatives in line with strategy, value, and delivery capacity. The question asks specifically for Operations capabilities, so only observability and configuration management satisfy the AWS CAF classification.

AWS CloudFormation enables infrastructure as code by allowing a company to describe AWS and supported third-party resources in template files. A template acts as a repeatable blueprint that defines the resources to create and their relevant properties and relationships. CloudFormation uses the template to provision and configure a stack, which allows the same infrastructure definition to be deployed consistently in another environment, account, or Region. AWS also provides an infrastructure-as-code generator that can scan eligible existing resources and generate a template that can be used to bring those resources under CloudFormation management or replicate them. Therefore, option A is correct. AWS Step Functions coordinates distributed application components and workflows by using state machines; it does not replicate infrastructure from resource templates. Amazon CloudFront is a content delivery network that caches and delivers content through edge locations. AWS CloudTrail records account activity and API events for auditing and governance. Neither CloudFront nor CloudTrail is an infrastructure provisioning service. The exam clue is “using templates”: AWS CloudFormation templates define resources and make repeatable, controlled infrastructure deployments possible.
