Question 1

Proseware Labs has already validated the surrounding application components. The remaining architecture requirement for its IoT ingestion service is to evaluate whether AWS can perform undifferentiated infrastructure or platform work on behalf of the team while minimizing ongoing operational burden. Which option is best? The current estate includes 28 AWS accounts and active workloads in us-east-1 and us-west-2. Prefer an AWS-managed capability when it meets the requirements with less operational overhead.

Prefer the purpose-built managed AWS service that satisfies functional, security, reliability, and performance requirements with less operational ownership
Use a staged deployment or upgrade plan with explicit change controls, validation gates, and rollback criteria
Use managed multi-AZ or multi-Region capabilities according to the failure scope, with tested application and database failover
Use KMS/service-native encryption and TLS for data protection, with AWS WAF, Shield, and managed security services as appropriate for the threat model

Correct answer: A

Why: Managed-service adoption is valuable when it reduces undifferentiated operations without violating control, performance, or portability requirements. This directly addresses the primary requirement and remains appropriate while minimizing ongoing operational burden.

Option review:

A: Managed-service adoption is valuable when it reduces undifferentiated operations without violating control, performance, or portability requirements. This directly addresses the primary requirement and remains appropriate while minimizing ongoing operational burden.

B: Professional architectures should treat upgrades as controlled changes with measurable entry, success, and rollback conditions. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to evaluate whether AWS can perform undifferentiated infrastructure or platform work on behalf of the team under the additional constraint of while minimizing ongoing operational burden.

C: Reliability depends on matching redundancy to the required failure domain and using managed failover where it reduces operational risk. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to evaluate whether AWS can perform undifferentiated infrastructure or platform work on behalf of the team under the additional constraint of while minimizing ongoing operational burden.

D: Encryption protects confidentiality, while AWS WAF, Shield, and related managed services mitigate web and network attacks at scale. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to evaluate whether AWS can perform undifferentiated infrastructure or platform work on behalf of the team under the additional constraint of while minimizing ongoing operational burden.

Learning point: Prefer the purpose-built managed AWS service that satisfies functional, security, reliability, and performance requirements with less operational ownership.

Select instance families that match resource characteristics, use Auto Scaling where appropriate, and rightsize from observed metrics
Model data transfer paths and managed-service costs with AWS pricing tools, reduce avoidable transfer, and enforce budgets/usage controls
Select the architecture that meets the declared recovery, security, and budget objectives together, and validate those objectives with monitoring and testing
Use Auto Scaling and managed integration services such as SQS, SNS, or Step Functions to create elastic, loosely coupled components

Correct answer: C

Option review:

A: Instance families provide different resource profiles; elasticity and rightsizing align capacity to workload behavior instead of static peak estimates. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to evaluate a design where encryption, automated recovery, and spend guardrails are all mandatory under the additional constraint of while keeping the design elastic as demand changes.

B: Data-transfer architecture can materially affect cost; expenditure controls and service selection should be designed with traffic flows and business value in mind. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to evaluate a design where encryption, automated recovery, and spend guardrails are all mandatory under the additional constraint of while keeping the design elastic as demand changes.

D: Elastic scaling and asynchronous decoupling reduce cascading failures and allow components to recover or scale independently. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to evaluate a design where encryption, automated recovery, and spend guardrails are all mandatory under the additional constraint of while keeping the design elastic as demand changes.

Question 19

During a multi-account governance review at Lucerne Publishing, the site reliability architect is designing a machine learning inference service. The requirement is to evaluate whether AWS can perform undifferentiated infrastructure or platform work on behalf of the team while using managed services when they satisfy the requirement. Which architecture is the best fit? The current estate includes 13 AWS accounts and active workloads in ap-southeast-1 and ap-southeast-2. Prefer an AWS-managed capability when it meets the requirements with less operational overhead.

Prefer the purpose-built managed AWS service that satisfies functional, security, reliability, and performance requirements with less operational ownership
Use measured access patterns and latency/throughput requirements to choose the storage and delivery architecture, then monitor the relevant performance metrics
Use narrowly scoped security groups and network ACLs as required, and use VPC endpoints or PrivateLink for supported private service integrations
Use multi-AZ or multi-Region deployment as required, with health-aware Route 53 or other routing and managed failover mechanisms

Correct answer: A

Option review:

B: Performance architecture should start from access patterns and measurable objectives, not from one default storage service. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to evaluate whether AWS can perform undifferentiated infrastructure or platform work on behalf of the team under the additional constraint of while using managed services when they satisfy the requirement.

C: Security groups and NACLs control network flows at different layers, while VPC endpoints avoid unnecessary public paths to supported services. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to evaluate whether AWS can perform undifferentiated infrastructure or platform work on behalf of the team under the additional constraint of while using managed services when they satisfy the requirement.

D: AWS global and regional infrastructure plus health-aware routing can preserve application availability when a location or component fails. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to evaluate whether AWS can perform undifferentiated infrastructure or platform work on behalf of the team under the additional constraint of while using managed services when they satisfy the requirement.

Question 20

Datum Analytics is documenting its target-state architecture. Which choice most accurately addresses the need to design a high-throughput architecture that remains available when one component slows down while using managed services when they satisfy the requirement? The current estate includes 20 AWS accounts and active workloads in eu-west-1 and eu-central-1. The team wants the most direct architecture decision for this requirement.
Use elastic stateless tiers with managed queues or events, caching, replicas, and service-specific scaling to decouple bottlenecks and preserve availability
Use narrowly scoped security groups and network ACLs as required, and use VPC endpoints or PrivateLink for supported private service integrations
Select instance families that match resource characteristics, use Auto Scaling where appropriate, and rightsize from observed metrics
Model data transfer paths and managed-service costs with AWS pricing tools, reduce avoidable transfer, and enforce budgets/usage controls

Correct answer: A

Option review:

A: Professional solution design combines multiple patterns so capacity, failure, and latency are isolated rather than propagated across the stack. This directly addresses the primary requirement and remains appropriate while using managed services when they satisfy the requirement.

B: Security groups and NACLs control network flows at different layers, while VPC endpoints avoid unnecessary public paths to supported services. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to design a high-throughput architecture that remains available when one component slows down under the additional constraint of while using managed services when they satisfy the requirement.

Question 21

A principal solutions architect at Wide World Importers is reviewing a IoT ingestion service. The business requires the team to evaluate a design where encryption, automated recovery, and spend guardrails are all mandatory while using managed services when they satisfy the requirement. Which design most directly satisfies the requirement? The current estate includes 27 AWS accounts and active workloads in us-east-1 and us-west-2. The design must preserve security and auditability while meeting the stated objective.

Use IAM roles or other temporary-credential patterns with least privilege, and automate patch compliance through Systems Manager or managed-service patching
Use infrastructure as code with CloudFormation and an automated CI/CD deployment strategy that supports health checks and rollback
Use a staged deployment or upgrade plan with explicit change controls, validation gates, and rollback criteria
Select the architecture that meets the declared recovery, security, and budget objectives together, and validate those objectives with monitoring and testing

Correct answer: D

Option review:

A: Temporary scoped credentials reduce secret exposure, and automated patch workflows improve compliance without expanding application privileges. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to evaluate a design where encryption, automated recovery, and spend guardrails are all mandatory under the additional constraint of while using managed services when they satisfy the requirement.

B: Versioned infrastructure and automated deployment pipelines reduce drift and make failed changes repeatable and reversible. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to evaluate a design where encryption, automated recovery, and spend guardrails are all mandatory under the additional constraint of while using managed services when they satisfy the requirement.

C: Professional architectures should treat upgrades as controlled changes with measurable entry, success, and rollback conditions. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to evaluate a design where encryption, automated recovery, and spend guardrails are all mandatory under the additional constraint of while using managed services when they satisfy the requirement.

D: AWS Well-Architected decisions should balance reliability, security, operational excellence, performance efficiency, and cost instead of optimizing a single pillar in isolation. This directly addresses the primary requirement and remains appropriate while using managed services when they satisfy the requirement.

Question 22

Bellows University is changing its batch settlement service as part of a security design review. Which AWS approach best enables the team to evaluate whether AWS can perform undifferentiated infrastructure or platform work on behalf of the team while keeping observability sufficient to validate the result? The current estate includes 34 AWS accounts and active workloads in us-east-1 and eu-west-1. Select the option that satisfies the requirement with the fewest unnecessary moving parts.

Use Auto Scaling and managed integration services such as SQS, SNS, or Step Functions to create elastic, loosely coupled components
Use IAM roles or other temporary-credential patterns with least privilege, and automate patch compliance through Systems Manager or managed-service patching
Prefer the purpose-built managed AWS service that satisfies functional, security, reliability, and performance requirements with less operational ownership
Use managed multi-AZ or multi-Region capabilities according to the failure scope, with tested application and database failover

Correct answer: C

Option review:

A: Elastic scaling and asynchronous decoupling reduce cascading failures and allow components to recover or scale independently. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to evaluate whether AWS can perform undifferentiated infrastructure or platform work on behalf of the team under the additional constraint of while keeping observability sufficient to validate the result.

B: Temporary scoped credentials reduce secret exposure, and automated patch workflows improve compliance without expanding application privileges. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to evaluate whether AWS can perform undifferentiated infrastructure or platform work on behalf of the team under the additional constraint of while keeping observability sufficient to validate the result.

C: Managed-service adoption is valuable when it reduces undifferentiated operations without violating control, performance, or portability requirements. This directly addresses the primary requirement and remains appropriate while keeping observability sufficient to validate the result.

D: Reliability depends on matching redundancy to the required failure domain and using managed failover where it reduces operational risk. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to evaluate whether AWS can perform undifferentiated infrastructure or platform work on behalf of the team under the additional constraint of while keeping observability sufficient to validate the result.

Question 23

An architecture board at Blue Yonder Airlines asks the enterprise architect to design a high-throughput architecture that remains available when one component slows down while keeping observability sufficient to validate the result for a machine learning inference service. Which recommendation is most appropriate? The current estate includes 41 AWS accounts and active workloads in ap-southeast-1 and ap-southeast-2. Choose the option that best meets the stated constraints without introducing an unrelated redesign.

Model data transfer paths and managed-service costs with AWS pricing tools, reduce avoidable transfer, and enforce budgets/usage controls
Use S3 storage classes and lifecycle policies, or equivalent service-native tiering, based on access frequency and retrieval requirements
Select instance families that match resource characteristics, use Auto Scaling where appropriate, and rightsize from observed metrics
Use elastic stateless tiers with managed queues or events, caching, replicas, and service-specific scaling to decouple bottlenecks and preserve availability

Correct answer: D

Option review:

A: Data-transfer architecture can materially affect cost; expenditure controls and service selection should be designed with traffic flows and business value in mind. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to design a high-throughput architecture that remains available when one component slows down under the additional constraint of while keeping observability sufficient to validate the result.

B: Storage tiering reduces cost when lifecycle transitions match real access patterns, minimum-storage-duration rules, and retrieval expectations. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to design a high-throughput architecture that remains available when one component slows down under the additional constraint of while keeping observability sufficient to validate the result.

Question 24

For a payment platform at City Power, a production readiness review identifies one priority: evaluate a design where encryption, automated recovery, and spend guardrails are all mandatory while keeping observability sufficient to validate the result. Which AWS design should the team choose? The current estate includes 48 AWS accounts and active workloads in eu-west-1 and eu-central-1. Assume all unspecified components already meet their requirements.

Select instance families that match resource characteristics, use Auto Scaling where appropriate, and rightsize from observed metrics
Select the architecture that meets the declared recovery, security, and budget objectives together, and validate those objectives with monitoring and testing
Use cost and utilization data to rightsize resources, then choose Savings Plans, Reserved Instances, Spot, or On-Demand according to predictability and interruption tolerance
Adopt the appropriate managed AWS service and use Systems Manager or service-native automation for configuration and patching

Correct answer: B

Option review:

A: Instance families provide different resource profiles; elasticity and rightsizing align capacity to workload behavior instead of static peak estimates. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to evaluate a design where encryption, automated recovery, and spend guardrails are all mandatory under the additional constraint of while keeping observability sufficient to validate the result.

B: AWS Well-Architected decisions should balance reliability, security, operational excellence, performance efficiency, and cost instead of optimizing a single pillar in isolation. This directly addresses the primary requirement and remains appropriate while keeping observability sufficient to validate the result.

C: Rightsizing addresses resource efficiency first; pricing models then reduce the cost of the correctly sized usage pattern. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to evaluate a design where encryption, automated recovery, and spend guardrails are all mandatory under the additional constraint of while keeping observability sufficient to validate the result.
