Question 220

A learner is explaining Amazon Neptune to colleagues facing this situation: a fraud team needs to query relationships and connections among entities. Which explanation is MOST accurate?

  1. RDS manages selected database infrastructure work for relational workloads, while users still control database schema and access.
  2. Database Migration Service helps migrate or replicate supported databases; it is not itself an application database engine.
  3. DynamoDB supports key-value and document data models and is not a general-purpose relational SQL database.
  4. Neptune supports graph data models for workloads centered on relationships among connected entities.

Explanation

Correct Answer

D:

Neptune supports graph data models for workloads centered on relationships among connected entities. The explanation directly connects Amazon Neptune to use Amazon Neptune for graph-oriented data relationships for the stated requirement.

Incorrect Answers

A:

This statement is true of Amazon RDS relational database, which addresses a web application needs a managed relational database that supports SQL queries and transactions. It does not explain the particular role of Amazon Neptune; Neptune supports graph data models for workloads centered on relationships among connected entities.

B:

This statement is true of AWS Database Migration Service, which addresses an enterprise needs help migrating data from a supported existing database to another endpoint. It does not explain the particular role of Amazon Neptune; Neptune supports graph data models for workloads centered on relationships among connected entities.

C:

This statement is true of Amazon DynamoDB, which addresses a game needs low-latency access to large volumes of key-value player state without managing servers. It does not explain the particular role of Amazon Neptune; Neptune supports graph data models for workloads centered on relationships among connected entities.

Question 221

A stakeholder is considering Hybrid cloud deployment because a bank must keep some applications on its own premises while using AWS for other services. What is the MOST relevant capability or benefit?

  1. Combine on-premises infrastructure with cloud resources under a hybrid approach
  2. Meet this requirement: a business analyst occasionally needs to view AWS resources through a browser interface
  3. Support scripted AWS API operations
  4. Interact with AWS services through supported API operations

Explanation

Correct Answer

A:

Combine on-premises infrastructure with cloud resources under a hybrid approach. A hybrid deployment model uses both on-premises environments and cloud infrastructure rather than moving every workload immediately. The stated need is specifically a bank must keep some applications on its own premises while using AWS for other services.

Incorrect Answers

B:

This outcome fits AWS Management Console: The AWS Management Console is a browser-based entry point for authorized AWS account users. The stakeholder requires the more specific capability provided by Hybrid cloud deployment, not that separate benefit.

C:

This outcome fits AWS CLI: The AWS CLI exposes AWS service operations through command-line commands suitable for controlled automation. The stakeholder requires the more specific capability provided by Hybrid cloud deployment, not that separate benefit.

D:

This outcome fits AWS service APIs: AWS APIs enable programmatic service access; management consoles and SDKs are other ways to use such capabilities. The stakeholder requires the more specific capability provided by Hybrid cloud deployment, not that separate benefit.

Question 222

Within the Security and Compliance domain, which business example MOST clearly illustrates AWS Secrets Manager, rather than a different AWS concept?

  1. A legacy automation application uses an AWS access-key ID and secret key for API access
  2. An application needs controlled storage and rotation of a database password
  3. A company wants staff to authenticate to AWS using its existing corporate identity provider
  4. A newly created AWS account still has its root user's password and no extra protection

Explanation

Correct Answer

B:

The decisive requirement is: Store and manage application secrets with AWS Secrets Manager. This is the role of AWS Secrets Manager. Secrets Manager manages sensitive credentials and supports rotation workflows; IAM policies determine who may retrieve a secret.

Incorrect Answers

A:

This describes a scenario for Access keys: treat access keys as sensitive credentials and rotate or replace them where appropriate. AWS access keys enable programmatic authentication and must not be committed to public repositories. It is not the most direct example of AWS Secrets Manager.

C:

This describes a scenario for Identity federation: federate existing enterprise identities instead of issuing separate permanent credentials. Federation integrates identity-provider authentication with AWS access, supporting centralized workforce identity management. It is not the most direct example of AWS Secrets Manager.

D:

This describes a scenario for Root user protection: secure the root identity with MFA and avoid routine root use. The root user has highly privileged account-wide capabilities and should be protected and used only when necessary. It is not the most direct example of AWS Secrets Manager.

Question 223

A stakeholder is considering Operating expenditure because a business pays recurring usage charges for AWS resources it uses this month. What is the MOST relevant capability or benefit?

  1. Let eligible costs rise and fall with actual resource consumption
  2. Reduce repetitive administrative work through consistent automation
  3. Classify cloud usage-based service payments as operating spending
  4. Include facilities, hardware, operations, and staffing in a long-term cost comparison

Explanation

Correct Answer

C:

Classify cloud usage-based service payments as operating spending. Variable cloud charges generally align with operating expense rather than a customer buying provider hardware. The stated need is specifically a business pays recurring usage charges for AWS resources it uses this month.

Incorrect Answers

A:

This outcome fits Variable costs: Variable cost follows utilization or usage rather than remaining fixed at a pre-purchased capacity level. The stakeholder requires the more specific capability provided by Operating expenditure, not that separate benefit.

B:

This outcome fits Automation savings: Automation can reduce manual effort and mistakes while making temporary resources easier to retire. The stakeholder requires the more specific capability provided by Operating expenditure, not that separate benefit.

D:

This outcome fits Total cost of ownership: Total cost of ownership considers direct and indirect costs, not only an instance hourly price. The stakeholder requires the more specific capability provided by Operating expenditure, not that separate benefit.

Question 224

A learner is explaining Variable costs to colleagues facing this situation: a retailer wants lower cloud expenses during months with fewer transactions. Which explanation is MOST accurate?

  1. BYOL may reduce duplicate license purchases when specific licensing rules and deployment requirements are satisfied.
  2. Variable cloud charges generally align with operating expense rather than a customer buying provider hardware.
  3. Automation can reduce manual effort and mistakes while making temporary resources easier to retire.
  4. Variable cost follows utilization or usage rather than remaining fixed at a pre-purchased capacity level.

Explanation

Correct Answer

D:

Variable cost follows utilization or usage rather than remaining fixed at a pre-purchased capacity level. The explanation directly connects Variable costs to let eligible costs rise and fall with actual resource consumption for the stated requirement.

Incorrect Answers

A:

This statement is true of Bring Your Own License, which addresses a company has eligible existing software licenses that might be usable on a cloud host. It does not explain the particular role of Variable costs; Variable cost follows utilization or usage rather than remaining fixed at a pre-purchased capacity level.

B:

This statement is true of Operating expenditure, which addresses a business pays recurring usage charges for AWS resources it uses this month. It does not explain the particular role of Variable costs; Variable cost follows utilization or usage rather than remaining fixed at a pre-purchased capacity level.

C:

This statement is true of Automation savings, which addresses a department repeatedly creates and deletes temporary test environments by hand. It does not explain the particular role of Variable costs; Variable cost follows utilization or usage rather than remaining fixed at a pre-purchased capacity level.

Question 225

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

  1. A research portal expects sustained growth from thousands to millions of visitors over several years
  2. A testing team needs temporary computing capacity immediately for a newly approved project
  3. Several departments need separate virtual workloads without each purchasing dedicated physical machines
  4. A small team prefers to focus on application features instead of replacing failed server hardware

Explanation

Correct Answer

A:

The decisive requirement is: Increase a system's capacity to handle a larger ongoing workload. This is the role of Scalability. Scalability is the ability to handle greater load by adding resources or increasing their capacity as an organization grows.

Incorrect Answers

B:

This describes a scenario for On-demand provisioning: provision capacity when requested rather than waiting for hardware ordering. AWS self-service resource provisioning reduces procurement lead time for many workloads. It is not the most direct example of Scalability.

C:

This describes a scenario for Resource pooling: share provider-managed infrastructure while retaining logical workload isolation. Cloud resource pooling supports multiple customers and workloads through provider-managed shared infrastructure with isolation controls. It is not the most direct example of Scalability.

D:

This describes a scenario for Reduced infrastructure maintenance: delegate physical infrastructure operation to the cloud provider. AWS handles the facilities and underlying physical infrastructure, freeing customers from those data-center tasks. It is not the most direct example of Scalability.

Question 226

Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: support serverless container compute?

  1. Amazon EC2
  2. AWS Fargate
  3. AWS Lambda
  4. Amazon EKS

Explanation

Correct Answer

B:

AWS Fargate directly addresses this outcome. Fargate supplies compute capacity for supported container tasks without customers administering container hosts. A common relevant example is: a development team wants to run supported containers without managing the underlying EC2 host fleet.

Incorrect Answers

A:

Amazon EC2 virtual servers instead focuses on a different requirement, such as a software vendor needs full control of a virtual machine operating system for a legacy application. EC2 offers virtual servers with selectable instance types and customer-managed guest operating systems. It is not the primary match for the requirement described here: support serverless container compute.

C:

AWS Lambda instead focuses on a different requirement, such as an online form should run short application code only when events occur without managing servers. Lambda executes event-triggered code without the customer managing underlying servers, subject to service limits. It is not the primary match for the requirement described here: support serverless container compute.

D:

Amazon EKS instead focuses on a different requirement, such as an organization wants managed Kubernetes control-plane capabilities for containerized workloads. EKS offers managed Kubernetes control-plane capabilities for applications using Kubernetes APIs. It is not the primary match for the requirement described here: support serverless container compute.

Question 227

A project manager compares Customer Lambda function code with other AWS concepts while considering this need: a Lambda function processes user data using application code written by a development team. Which pairing assigns the responsibilities or benefits correctly?

  1. Customer Lambda function code: aWS operates and maintains the managed S3 storage infrastructure; AWS S3 infrastructure durability: the customer is responsible for the function code and its business logic
  2. Customer Lambda function code: aWS maintains the physical host and underlying cloud virtualization infrastructure; AWS EC2 host infrastructure: the customer is responsible for the function code and its business logic
  3. Customer Lambda function code: the customer is responsible for the function code and its business logic; Shared responsibility varies by service: customer operational responsibilities generally decrease as more service layers become AWS-managed
  4. Customer Lambda function code: customer operational responsibilities generally decrease as more service layers become AWS-managed; Shared responsibility varies by service: the customer is responsible for the function code and its business logic

Explanation

Correct Answer

C:

The first pairing identifies Customer Lambda function code with its actual role: the customer is responsible for the function code and its business logic. Serverless eliminates server administration for the customer, not their responsibility for their own application code and data handling. The comparison is valid because Shared responsibility varies by service instead addresses customer operational responsibilities generally decrease as more service layers become AWS-managed.

Incorrect Answers

A:

The roles are swapped. AWS S3 infrastructure durability is associated with aWS operates and maintains the managed S3 storage infrastructure; Customer Lambda function code instead has the role: The customer is responsible for the function code and its business logic. Serverless eliminates server administration for the customer, not their responsibility for their own application code and data handling.

B:

The roles are swapped. AWS EC2 host infrastructure is associated with aWS maintains the physical host and underlying cloud virtualization infrastructure; Customer Lambda function code instead has the role: The customer is responsible for the function code and its business logic. Serverless eliminates server administration for the customer, not their responsibility for their own application code and data handling.

D:

The roles are swapped. Shared responsibility varies by service is associated with customer operational responsibilities generally decrease as more service layers become AWS-managed; Customer Lambda function code instead has the role: The customer is responsible for the function code and its business logic. Serverless eliminates server administration for the customer, not their responsibility for their own application code and data handling.

Question 228

Within the Security and Compliance domain, which business example MOST clearly illustrates Customer encryption choices, rather than a different AWS concept?

  1. A company uses EC2 but asks who maintains the hardware supporting its virtual machines
  2. A team accidentally publishes an S3 bucket containing internal reports
  3. A Lambda function processes user data using application code written by a development team
  4. A company wants to ensure its application stores sensitive objects with required encryption settings

Explanation

Correct Answer

D:

The decisive requirement is: The customer chooses applicable encryption configuration and key-access policies. This is the role of Customer encryption choices. Managed services can provide encryption capabilities, but customers must select and govern settings needed for their data.

Incorrect Answers

A:

This describes a scenario for AWS EC2 host infrastructure: aWS maintains the physical host and underlying cloud virtualization infrastructure. AWS is responsible for facilities, physical servers and underlying cloud infrastructure for EC2. It is not the most direct example of Customer encryption choices.

B:

This describes a scenario for Customer S3 bucket access: the customer must correct the bucket access policy and exposure settings. AWS operates the S3 storage infrastructure, but customers configure authorized access to their buckets and objects. It is not the most direct example of Customer encryption choices.

C:

This describes a scenario for Customer Lambda function code: the customer is responsible for the function code and its business logic. Serverless eliminates server administration for the customer, not their responsibility for their own application code and data handling. It is not the most direct example of Customer encryption choices.

Question 229

A project manager compares AWS security best practices with other AWS concepts while considering this need: an organization needs general recommendations to harden AWS workloads. Which pairing assigns the responsibilities or benefits correctly?

  1. AWS security best practices: meet this requirement: an organization needs general recommendations to harden AWS workloads; AWS Marketplace: meet this requirement: a company wants to evaluate a third-party security product compatible with AWS workloads
  2. AWS security best practices: assist security investigations; Amazon Detective: meet this requirement: an organization needs general recommendations to harden AWS workloads
  3. AWS security best practices: meet this requirement: a company wants to evaluate a third-party security product compatible with AWS workloads; AWS Marketplace: meet this requirement: an organization needs general recommendations to harden AWS workloads
  4. AWS security best practices: support DDoS protection capabilities; AWS Shield: meet this requirement: an organization needs general recommendations to harden AWS workloads

Explanation

Correct Answer

A:

The first pairing identifies AWS security best practices with its actual role: use AWS security best-practice resources and service-specific recommendations. AWS security guidance supports safe decisions, while controls still need deliberate configuration by the customer. The comparison is valid because AWS Marketplace security software instead addresses find third-party software offerings through AWS Marketplace.

Incorrect Answers

B:

The roles are swapped. Amazon Detective is associated with use Amazon Detective to assist security investigations; AWS security best practices instead has the role: Use AWS security best-practice resources and service-specific recommendations. AWS security guidance supports safe decisions, while controls still need deliberate configuration by the customer.

C:

The roles are swapped. AWS Marketplace is associated with find third-party software offerings through AWS Marketplace; AWS security best practices instead has the role: Use AWS security best-practice resources and service-specific recommendations. AWS security guidance supports safe decisions, while controls still need deliberate configuration by the customer.

D:

The roles are swapped. AWS Shield is associated with use AWS Shield for DDoS protection capabilities; AWS security best practices instead has the role: Use AWS security best-practice resources and service-specific recommendations. AWS security guidance supports safe decisions, while controls still need deliberate configuration by the customer.

Question 230

A project manager compares AWS Trusted Advisor with other AWS concepts while considering this need: a small team wants to find certain common AWS account configuration risks through recommendations. Which pairing assigns the responsibilities or benefits correctly?

  1. AWS Trusted Advisor: assist security investigations; Amazon Detective: meet this requirement: a small team wants to find certain common AWS account configuration risks through recommendations
  2. AWS Trusted Advisor: meet this requirement: a small team wants to find certain common AWS account configuration risks through recommendations; Amazon Detective: assist security investigations
  3. AWS Trusted Advisor: enable supported cross-account resource sharing; AWS Resource Access Manager: meet this requirement: a small team wants to find certain common AWS account configuration risks through recommendations
  4. AWS Trusted Advisor: support documented guidance; AWS Knowledge Center: meet this requirement: a small team wants to find certain common AWS account configuration risks through recommendations

Explanation

Correct Answer

B:

The first pairing identifies AWS Trusted Advisor with its actual role: review supported security recommendations in AWS Trusted Advisor. Trusted Advisor provides best-practice guidance in supported categories including security, cost and service limits. The comparison is valid because Amazon Detective investigations instead addresses use Amazon Detective to assist security investigations.

Incorrect Answers

A:

The roles are swapped. Amazon Detective is associated with use Amazon Detective to assist security investigations; AWS Trusted Advisor instead has the role: Review supported security recommendations in AWS Trusted Advisor. Trusted Advisor provides best-practice guidance in supported categories including security, cost and service limits.

C:

The roles are swapped. AWS Resource Access Manager is associated with use AWS Resource Access Manager for supported cross-account resource sharing; AWS Trusted Advisor instead has the role: Review supported security recommendations in AWS Trusted Advisor. Trusted Advisor provides best-practice guidance in supported categories including security, cost and service limits.
