A manager confuses an Availability Zone with an edge content-cache location.
Which AWS concept, service, or approach best meets the need described?
Edge locations serve nearby delivery needs; Availability Zones host fault-isolated regional workloads. For the described requirement, distinguish edge caching from regional Availability Zone compute placement.
Choosing Region determines the geographic location of many deployed resources and data residency choices.
Using different AWS Regions can reduce dependence on one geographic Region when application design supports recovery.
Availability Zones are separate fault-isolation locations within a Region.
A streaming analytics team needs to ingest high-throughput event records as they arrive.
Which observation would best confirm that the intended cloud outcome is being achieved?
Kinesis provides streaming-data services rather than a long-term relational warehouse.
Kendra indexes supported content sources and supports natural-language search relevance.
Athena supports serverless interactive SQL analysis of data stored in S3.
SageMaker AI provides managed capabilities for training and hosting ML models.
A relational database needs to move to AWS while the business minimizes service interruption.
Which AWS concept, service, or approach best meets the need described?
AWS DMS helps move databases and replicate changes rather than serving as a general file-transfer service. For the described requirement, use AWS Database Migration Service for database migration with ongoing change replication where supported.
AWS CAF considers business risk, efficiency, revenue opportunity and broader transformation outcomes.
Replatforming changes selected platform components while retaining the application's fundamental design.
Repurchasing substitutes a new product licensing and delivery model for a legacy implementation.
A company needs an external identity to access an AWS role for a bounded period.
Which observation would best confirm that the intended cloud outcome is being achieved?
STS role assumption permits controlled cross-account access without sharing long-lived access keys.
Federation leverages an established identity provider to issue access without separate local passwords.
Secrets Manager is purpose-built for managing secret values instead of exposing credentials in source files.
Authentication establishes who the principal is; authorization evaluates what the principal may do.
A company has a steady predictable baseline of EC2 compute use over several years.
Which AWS pricing, billing, or support approach best matches the requirement?
Reserved Instance pricing offers commitment-based discounts subject to instance attributes and purchasing terms. For the described requirement, evaluate eligible Reserved Instances for predictable matching EC2 usage.
Capacity Reservations address eligible instance-capacity availability rather than inherently reducing the cost of the instances.
On-Demand billing allows eligible EC2 capacity without an upfront duration commitment, though its unit price may be higher.
Data leaving AWS can incur transfer charges based on service and path, while ordinary ingress pricing often differs.
A product needs managed web-request filtering for malicious SQL injection signatures.
Which observation would best confirm that the intended cloud outcome is being achieved?
WAF inspects HTTP requests with web ACL rules and complements rather than replaces network-layer controls.
AWS publishes security practices and service guidance through official documentation and blogs.
GuardDuty uses supported signals to report suspected threats rather than inventorying all business contracts.
Inspector analyzes supported workloads for exposure and software vulnerabilities, not user login events.
A company has thousands of connected sensors that must securely send device telemetry to the cloud.
Which AWS concept, service, or approach best meets the need described?
IoT Core supports communication between approved devices and cloud services. For the described requirement, use AWS IoT Core for secure connected-device messaging and cloud integration.
SNS can distribute published messages to configured endpoints and subscribers.
Amazon Connect supports contact-center interactions and routing rather than bulk marketing email delivery.
EventBridge routes matching events from supported sources to configured destinations.
A legacy monolith requires a new architecture before it can meet future scale and resilience goals.
Which observation would best confirm that the intended cloud outcome is being achieved?
Refactoring involves significant application design changes to exploit cloud-native capabilities.
Replatforming changes selected platform components while retaining the application's fundamental design.
Rehosting preserves much of the existing application architecture during the initial relocation.
Application retirement eliminates the maintenance and migration burden for systems no longer needed.
An operations team expects AWS to handle all failures caused by its own application deployment.
Which observation would best confirm that the intended cloud outcome is being achieved?
AWS infrastructure availability does not transfer responsibility for defects in customer-owned business applications.
AWS secures the service infrastructure while customers control authorization and exposure of their S3 objects.
Managed database services reduce infrastructure work but do not determine the business sensitivity of stored records.
The model divides accountability rather than transferring all security decisions to one party.
An application owner asks for a dashboard of CPU utilization and alarm thresholds.
Which AWS concept, service, or approach best meets the need described?
CloudWatch provides metric visibility and alarm reactions; it is not a replacement for CloudTrail API audit logs. For the described requirement, use Amazon CloudWatch metrics and alarms for operational monitoring.
AWS WAF evaluates layer-7 web requests using rules instead of replacing VPC network routing.
An organization trail helps collect supported account activity across participating AWS Organizations accounts.
Audit Manager helps gather evidence against assessment controls but does not certify a customer's entire workload.
A company wants to deploy containerized services using AWS-supported scheduling without managing Kubernetes itself.
Which AWS concept, service, or approach best meets the need described?
Amazon ECS manages placement and service operation of containers in an AWS-native orchestration model. For the described requirement, choose Amazon ECS for AWS-native container orchestration.
Fargate supplies the underlying capacity for containers used with supported ECS or EKS configurations.
Lambda executes functions on demand and manages underlying compute for the customer.
Lightsail offers simplified VPS plans with predictable bundles for straightforward applications.
