Question 40

Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: reduce repetitive administrative work through consistent automation?

  1. Operating expenditure
  2. Total cost of ownership
  3. License-included pricing
  4. Automation savings

Explanation

Correct Answer

D:

Automation savings directly addresses this outcome. Automation can reduce manual effort and mistakes while making temporary resources easier to retire. A common relevant example is: a department repeatedly creates and deletes temporary test environments by hand.

Incorrect Answers

A:

Operating expenditure instead focuses on a different requirement, such as a business pays recurring usage charges for AWS resources it uses this month. Variable cloud charges generally align with operating expense rather than a customer buying provider hardware. It is not the primary match for the requirement described here: reduce repetitive administrative work through consistent automation.

B:

Total cost of ownership instead focuses on a different requirement, such as a finance director compares AWS migration with building another private data center. Total cost of ownership considers direct and indirect costs, not only an instance hourly price. It is not the primary match for the requirement described here: reduce repetitive administrative work through consistent automation.

C:

License-included pricing instead focuses on a different requirement, such as a team prefers a cloud software offering whose price includes the relevant software license. License-included pricing is distinct from providing a separately acquired customer license under BYOL. It is not the primary match for the requirement described here: reduce repetitive administrative work through consistent automation.

Question 41

A project manager compares Idle resource spending with other AWS concepts while considering this need: an internal testing account leaves unused compute instances running every weekend. Which pairing assigns the responsibilities or benefits correctly?

  1. Idle resource spending: avoid paying for unnecessary always-on capacity by managing idle resources; Operating expenditure: classify cloud usage-based service payments as operating spending
  2. Idle resource spending: choose resource sizes appropriate for actual workload utilization; Rightsizing: avoid paying for unnecessary always-on capacity by managing idle resources
  3. Idle resource spending: evaluate use of qualifying existing software licenses subject to vendor and AWS terms; Bring Your Own License: avoid paying for unnecessary always-on capacity by managing idle resources
  4. Idle resource spending: classify cloud usage-based service payments as operating spending; Operating expenditure: avoid paying for unnecessary always-on capacity by managing idle resources

Explanation

Correct Answer

A:

The first pairing identifies Idle resource spending with its actual role: avoid paying for unnecessary always-on capacity by managing idle resources. Idle provisioned resources may continue to generate charges; matching uptime to need reduces wasted spending. The comparison is valid because Operating expenditure instead addresses classify cloud usage-based service payments as operating spending.

Incorrect Answers

B:

The roles are swapped. Rightsizing is associated with choose resource sizes appropriate for actual workload utilization; Idle resource spending instead has the role: Avoid paying for unnecessary always-on capacity by managing idle resources. Idle provisioned resources may continue to generate charges; matching uptime to need reduces wasted spending.

C:

The roles are swapped. Bring Your Own License is associated with evaluate use of qualifying existing software licenses subject to vendor and AWS terms; Idle resource spending instead has the role: Avoid paying for unnecessary always-on capacity by managing idle resources. Idle provisioned resources may continue to generate charges; matching uptime to need reduces wasted spending.

D:

The roles are swapped. Operating expenditure is associated with classify cloud usage-based service payments as operating spending; Idle resource spending instead has the role: Avoid paying for unnecessary always-on capacity by managing idle resources. Idle provisioned resources may continue to generate charges; matching uptime to need reduces wasted spending.

Question 42

Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: the customer chooses applicable encryption configuration and key-access policies?

  1. Shared responsibility varies by service
  2. Customer encryption choices
  3. Customer Lambda function code
  4. Customer S3 bucket access

Explanation

Correct Answer

B:

Customer encryption choices directly addresses this outcome. Managed services can provide encryption capabilities, but customers must select and govern settings needed for their data. A common relevant example is: a company wants to ensure its application stores sensitive objects with required encryption settings.

Incorrect Answers

A:

Shared responsibility varies by service instead focuses on a different requirement, such as a technology leader compares the management obligations of EC2, RDS and Lambda. Responsibility depends on the service model: managing an EC2 guest OS differs from managing application code on Lambda. It is not the primary match for the requirement described here: the customer chooses applicable encryption configuration and key-access policies.

C:

Customer Lambda function code instead focuses on a different requirement, such as a Lambda function processes user data using application code written by a development team. Serverless eliminates server administration for the customer, not their responsibility for their own application code and data handling. It is not the primary match for the requirement described here: the customer chooses applicable encryption configuration and key-access policies.

D:

Customer S3 bucket access instead focuses on a different requirement, such as a team accidentally publishes an S3 bucket containing internal reports. AWS operates the S3 storage infrastructure, but customers configure authorized access to their buckets and objects. It is not the primary match for the requirement described here: the customer chooses applicable encryption configuration and key-access policies.

Question 43

A project manager compares Amazon SNS with other AWS concepts while considering this need: a monitoring event should send notifications to multiple subscribed endpoints. Which pairing assigns the responsibilities or benefits correctly?

  1. Amazon SNS: support event bus routing and integration; Amazon EventBridge: support publish-subscribe notifications and fan-out
  2. Amazon SNS: support managed workflow orchestration; AWS Step Functions: support publish-subscribe notifications and fan-out
  3. Amazon SNS: support publish-subscribe notifications and fan-out; Amazon SES: support application email delivery
  4. Amazon SNS: support application email delivery; Amazon SES: support publish-subscribe notifications and fan-out

Explanation

Correct Answer

C:

The first pairing identifies Amazon SNS with its actual role: use Amazon SNS for publish-subscribe notifications and fan-out. SNS distributes published messages to subscribed destinations; it is not a relational database. The comparison is valid because Amazon SES instead addresses use Amazon Simple Email Service for application email delivery.

Incorrect Answers

A:

The roles are swapped. Amazon EventBridge is associated with use Amazon EventBridge for event bus routing and integration; Amazon SNS instead has the role: Use Amazon SNS for publish-subscribe notifications and fan-out. SNS distributes published messages to subscribed destinations; it is not a relational database.

B:

The roles are swapped. AWS Step Functions is associated with use AWS Step Functions for managed workflow orchestration; Amazon SNS instead has the role: Use Amazon SNS for publish-subscribe notifications and fan-out. SNS distributes published messages to subscribed destinations; it is not a relational database.

D:

The roles are swapped. Amazon SES is associated with use Amazon Simple Email Service for application email delivery; Amazon SNS instead has the role: Use Amazon SNS for publish-subscribe notifications and fan-out. SNS distributes published messages to subscribed destinations; it is not a relational database.

Question 44

A company needs a document specifying allowed or denied AWS actions on selected resources. Which AWS service or cloud concept is the MOST direct match for this need?

  1. AWS STS
  2. Cross-account role access
  3. Identity federation
  4. IAM policies

Explanation

Correct Answer

D:

IAM policies fits the need because an IAM policy expresses permissions; it is not itself a human identity or a network firewall. The relevant capability or responsibility is: Use IAM policy statements that define access permissions.

Incorrect Answers

A:

AWS STS role assumption is associated with a different use case: an application needs temporary AWS credentials after assuming an authorized IAM role. STS provides temporary credentials for permitted role or federated sessions; it does not issue physical security tokens. The question instead focuses on a company needs a document specifying allowed or denied AWS actions on selected resources; IAM policies is the more direct match.

B:

Cross-account role access is associated with a different use case: an auditor from a separate AWS account needs time-limited access to approved audit resources. Cross-account role trust enables authorized temporary access without copying long-term keys to the external account. The question instead focuses on a company needs a document specifying allowed or denied AWS actions on selected resources; IAM policies is the more direct match.

C:

Identity federation is associated with a different use case: a company wants staff to authenticate to AWS using its existing corporate identity provider. Federation integrates identity-provider authentication with AWS access, supporting centralized workforce identity management. The question instead focuses on a company needs a document specifying allowed or denied AWS actions on selected resources; IAM policies is the more direct match.

Question 45

Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: meet this requirement: a company needs a document specifying allowed or denied AWS actions on selected resources?

  1. IAM policies
  2. Principle of least privilege
  3. AWS STS
  4. AWS IAM Identity Center

Explanation

Correct Answer

A:

IAM policies directly addresses this outcome. An IAM policy expresses permissions; it is not itself a human identity or a network firewall. A common relevant example is: a company needs a document specifying allowed or denied AWS actions on selected resources.

Incorrect Answers

B:

Principle of least privilege instead focuses on a different requirement, such as a developer only needs read access to one object storage bucket for a project. Least privilege restricts permissions to required actions and resources rather than granting broad administrator access. It is not the primary match for the requirement described here: meet this requirement: a company needs a document specifying allowed or denied AWS actions on selected resources.

C:

AWS STS role assumption instead focuses on a different requirement, such as an application needs temporary AWS credentials after assuming an authorized IAM role. STS provides temporary credentials for permitted role or federated sessions; it does not issue physical security tokens. It is not the primary match for the requirement described here: meet this requirement: a company needs a document specifying allowed or denied AWS actions on selected resources.

D:

AWS IAM Identity Center instead focuses on a different requirement, such as employees need centralized workforce access to multiple AWS accounts using corporate identities. IAM Identity Center connects workforce identities and assigns access across AWS accounts and compatible applications. It is not the primary match for the requirement described here: meet this requirement: a company needs a document specifying allowed or denied AWS actions on selected resources.

Question 46

A stakeholder is considering Amazon Neptune because a fraud team needs to query relationships and connections among entities. What is the MOST relevant capability or benefit?

  1. Support cloud data warehousing
  2. Support graph-oriented data relationships
  3. Enable supported MongoDB-compatible document workloads
  4. Support a managed relational database compatible with supported engines

Explanation

Correct Answer

B:

Use Amazon Neptune for graph-oriented data relationships. Neptune supports graph data models for workloads centered on relationships among connected entities. The stated need is specifically a fraud team needs to query relationships and connections among entities.

Incorrect Answers

A:

This outcome fits Amazon Redshift: Redshift is designed for analytics and data warehousing rather than being a low-latency transactional key-value store. The stakeholder requires the more specific capability provided by Amazon Neptune, not that separate benefit.

C:

This outcome fits Amazon DocumentDB: DocumentDB is a managed document database, distinct from relational engines and caching services. The stakeholder requires the more specific capability provided by Amazon Neptune, not that separate benefit.

D:

This outcome fits Amazon Aurora: Aurora is an AWS-managed relational database designed for cloud operation and compatible with selected open-source SQL engines. The stakeholder requires the more specific capability provided by Amazon Neptune, not that separate benefit.

Question 47

A stakeholder is considering Reliability pillar because an application needs to recover predictably from failures and adapt when demand changes. What is the MOST relevant capability or benefit?

  1. Avoid unnecessary expense while delivering required outcomes
  2. Protect information and systems using risk-aware controls
  3. Recover from disruptions and perform the intended function consistently
  4. Use computing resources efficiently as requirements change

Explanation

Correct Answer

C:

Recover from disruptions and perform the intended function consistently. The Reliability pillar emphasizes recovery, distributed design, and meeting availability requirements. The stated need is specifically an application needs to recover predictably from failures and adapt when demand changes.

Incorrect Answers

A:

This outcome fits Cost Optimization pillar: Cost Optimization includes understanding expenditure, selecting cost-effective resources, and managing demand and supply. The stakeholder requires the more specific capability provided by Reliability pillar, not that separate benefit.

B:

This outcome fits Security pillar: The Security pillar addresses identity, detection, infrastructure and data protection in the AWS Well-Architected Framework. The stakeholder requires the more specific capability provided by Reliability pillar, not that separate benefit.

D:

This outcome fits Performance Efficiency pillar: The Performance Efficiency pillar focuses on choosing and adapting resources to match workload performance needs. The stakeholder requires the more specific capability provided by Reliability pillar, not that separate benefit.

Question 48

Within the Cloud Concepts domain, which business example MOST clearly illustrates Retiring an application, rather than a different AWS concept?

  1. A company can move a supported virtualized environment to AWS while maintaining its familiar virtualization stack
  2. A business is willing to redesign a tightly coupled application into cloud-native components
  3. A business must keep a legacy production system on premises until a contractual restriction expires
  4. An inventory review discovers a legacy reporting system with no users or business dependency

Explanation

Correct Answer

D:

The decisive requirement is: Decommission an unneeded application rather than migrate it. This is the role of Retiring an application. Retiring eliminates redundant or unused workloads so migration effort is not spent on systems with no continuing value.

Incorrect Answers

A:

This describes a scenario for Relocating a workload: move compatible virtual machines or virtualized infrastructure with minimal change. Relocating retains much of the underlying virtualization model while shifting where it runs. It is not the most direct example of Retiring an application.

B:

This describes a scenario for Refactoring migration: make significant application changes to use cloud-native capabilities. Refactoring transforms the application architecture, rather than simply moving the existing runtime to the cloud. It is not the most direct example of Retiring an application.

C:

This describes a scenario for Retaining a workload: leave a selected workload in its existing environment for now. Retaining is an intentional decision to defer migration when business or technical constraints make an immediate move inappropriate. It is not the most direct example of Retiring an application.

Question 49

A learner is explaining AWS SDKs to colleagues facing this situation: a developer wants a Java application to interact with AWS services using language libraries. Which explanation is MOST accurate?

  1. AWS SDKs provide language-specific APIs and tooling for integrating application software with AWS.
  2. CloudFormation uses templates and stacks to create and manage supported AWS resources consistently.
  3. Outposts extends supported AWS infrastructure and services to customer locations where local processing or data needs apply.
  4. The AWS Management Console is a browser-based entry point for authorized AWS account users.

Explanation

Correct Answer

A:

AWS SDKs provide language-specific APIs and tooling for integrating application software with AWS. The explanation directly connects AWS SDKs to use an AWS SDK to call service APIs from application code for the stated requirement.

Incorrect Answers

B:

This statement is true of AWS CloudFormation, which addresses a cloud team must define a repeatable infrastructure configuration under version control. It does not explain the particular role of AWS SDKs; AWS SDKs provide language-specific APIs and tooling for integrating application software with AWS.

C:

This statement is true of AWS Outposts, which addresses a manufacturer needs AWS-managed hardware and selected cloud services in its own facility. It does not explain the particular role of AWS SDKs; AWS SDKs provide language-specific APIs and tooling for integrating application software with AWS.

D:

This statement is true of AWS Management Console, which addresses a business analyst occasionally needs to view AWS resources through a browser interface. It does not explain the particular role of AWS SDKs; AWS SDKs provide language-specific APIs and tooling for integrating application software with AWS.

Question 50

Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: support encrypted hybrid network connectivity?

  1. AWS Transit Gateway
  2. AWS Site-to-Site VPN
  3. Amazon VPC
  4. Security groups

Explanation

Correct Answer

B:

AWS Site-to-Site VPN directly addresses this outcome. Site-to-Site VPN provides encrypted tunnels using internet-based connectivity, subject to supported gateway arrangements. A common relevant example is: a company wants an encrypted tunnel between an office network and its AWS VPC over the internet.

Incorrect Answers

A:

AWS Transit Gateway instead focuses on a different requirement, such as a company needs a central networking hub connecting multiple VPCs and applicable on-premises networks. Transit Gateway acts as a regional routing hub for supported VPC and network attachments. It is not the primary match for the requirement described here: support encrypted hybrid network connectivity.

C:

Amazon VPC instead focuses on a different requirement, such as a team wants a logically isolated network environment for its AWS compute resources. A VPC is a logically isolated virtual network in which customers can organize subnets, routes and connectivity. It is not the primary match for the requirement described here: support encrypted hybrid network connectivity.

D:

Security groups instead focuses on a different requirement, such as an EC2 workload should allow only specified inbound and outbound connections at the resource level. Security groups control permitted traffic for associated resources and automatically allow response traffic to allowed flows. It is not the primary match for the requirement described here: support encrypted hybrid network connectivity.
