A business needs disaster recovery in a separate geographic location from its primary AWS workload.
Which AWS concept, service, or approach best meets the need described?
Using different AWS Regions can reduce dependence on one geographic Region when application design supports recovery. For the described requirement, recognize multi-Region deployment as a regional disaster-recovery strategy.
Choosing Region determines the geographic location of many deployed resources and data residency choices.
Multiple instances sharing one AZ remain exposed to an AZ-wide event despite instance-level redundancy.
A Region is a geographic AWS area containing multiple isolated Availability Zones.
A business needs a managed relational database with an AWS-optimized engine compatible with MySQL or PostgreSQL.
Which observation would best confirm that the intended cloud outcome is being achieved?
Aurora is AWS's managed relational engine designed for cloud operation and supported compatibility.
Amazon RDS operates supported relational databases with managed infrastructure and routine platform tasks.
AWS SCT helps assess and convert database schema objects during migration between different engines.
Amazon Redshift is designed for analytics and warehouse workloads rather than conventional app transactions.
A platform department wants a managed Kubernetes control plane in AWS for its container applications.
Which AWS concept, service, or approach best meets the need described?
Amazon EKS provides AWS-managed Kubernetes control-plane capabilities for Kubernetes-based applications. For the described requirement, choose Amazon EKS to run managed Kubernetes clusters in AWS.
Lightsail offers simplified VPS plans with predictable bundles for straightforward applications.
Lambda executes functions on demand and manages underlying compute for the customer.
A load balancer forwards requests to configured healthy application targets and supports availability.
A database migration team must transform incompatible source SQL schema constructs to a new engine.
Which AWS concept, service, or approach best meets the need described?
AWS SCT helps assess and convert database schema objects during migration between different engines. For the described requirement, use AWS Schema Conversion Tool for eligible heterogeneous database schema conversion.
DynamoDB is a managed NoSQL database suited to key-based access and flexible item structures.
Amazon Redshift is designed for analytics and warehouse workloads rather than conventional app transactions.
ElastiCache supports low-latency in-memory access and can reduce load on a persistent system of record.
An organization notices unused long-lived access keys attached to old identities.
Which observation would best confirm that the intended cloud outcome is being achieved?
Unused permanent keys expand the credential attack surface without supporting an active business function.
MFA adds a second authentication factor to protect against password-only compromise.
IAM user groups let administrators attach permissions once for a collection of users.
IAM policies express permitted actions on supported resources; broad wildcard privileges are usually unnecessary.
A customer wants a Well-Architected pillar for choosing efficient technologies and resources for a workload.
Which AWS concept, service, or approach best meets the need described?
Performance efficiency concerns effective resource selection, adaptation and continued performance improvement. For the described requirement, use the performance efficiency pillar to select resources aligned to workload characteristics.
Sustainability encourages efficient resource usage and avoiding unnecessary capacity and processing.
Operational failures from unsafe processes require process and automation improvement, not simply bigger resources.
The pillars are operational excellence, security, reliability, performance efficiency, cost optimization and sustainability, not individual AWS services.
An operations manager wants to distinguish DDoS protections from application authorization policies.
Which AWS concept, service, or approach best meets the need described?
Shield is focused on denial-of-service defense whereas IAM evaluates principal permissions. For the described requirement, identify AWS Shield capabilities for DDoS threat protection.
Security Hub provides central visibility into supported findings and controls instead of replacing every scanner.
Inspector analyzes supported workloads for exposure and software vulnerabilities, not user login events.
Trusted Advisor evaluates selected account checks and is not the same as a complete security audit.
A cloud user wants AWS-authored guidance about current security recommendations and threats.
Which AWS concept, service, or approach best meets the need described?
AWS publishes security practices and service guidance through official documentation and blogs. For the described requirement, consult AWS Security Blog and official security documentation for authoritative guidance.
Firewall Manager supports organization-level security-policy management for selected AWS protection services.
Inspector analyzes supported workloads for exposure and software vulnerabilities, not user login events.
Security Hub provides central visibility into supported findings and controls instead of replacing every scanner.
A product team needs to forecast the price of a proposed architecture before creating its resources.
Which AWS pricing, billing, or support approach best matches the requirement?
Pricing Calculator models estimated charges for configured usage assumptions before deployment. For the described requirement, use AWS Pricing Calculator to estimate prospective AWS service costs.
Cost and Usage reports provide granular cost and usage data for analysis rather than a simple monthly invoice summary.
AWS Budgets compares actual and forecast cost to budget thresholds and can notify stakeholders.
Cost Explorer supports cost and usage analysis and trends rather than provisioning resource changes.
A company wants centrally consolidated invoices for its development and production accounts.
Which observation would best confirm that the intended cloud outcome is being achieved?
Consolidated billing enables central management of multiple account bills and eligible shared pricing benefits.
Pricing Calculator models estimated charges for configured usage assumptions before deployment.
The AWS billing console provides cost and payment visibility rather than being a service deployment interface.
Cost Explorer supports cost and usage analysis and trends rather than provisioning resource changes.
A charity's donation portal receives only occasional bursts when fundraising campaigns go viral.
Which observation would best confirm that the intended cloud outcome is being achieved?
Elasticity aligns provisioned resources with current need instead of maintaining permanent peak-sized local capacity.
Provisioning through AWS APIs and consoles improves agility by reducing procurement delays for new environments.
AWS supplies resilient infrastructure options but application architecture and chosen deployment patterns still affect availability.
AWS global infrastructure enables geographic reach and faster regional market entry while the business remains responsible for its application.
