Question 30

An auditor from a separate AWS account needs time-limited access to approved audit resources. Which AWS service or cloud concept is the MOST direct match for this need?

  1. Identity federation
  2. Cross-account role access
  3. AWS Secrets Manager
  4. AWS STS

Explanation

Correct Answer

B:

Cross-account role access fits the need because cross-account role trust enables authorized temporary access without copying long-term keys to the external account. The relevant capability or responsibility is: Assume an appropriately trusted IAM role across accounts.

Incorrect Answers

A:

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 an auditor from a separate AWS account needs time-limited access to approved audit resources; Cross-account role access is the more direct match.

C:

AWS Secrets Manager is associated with a different use case: an application needs controlled storage and rotation of a database password. Secrets Manager manages sensitive credentials and supports rotation workflows; IAM policies determine who may retrieve a secret. The question instead focuses on an auditor from a separate AWS account needs time-limited access to approved audit resources; Cross-account role access is the more direct match.

D:

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 an auditor from a separate AWS account needs time-limited access to approved audit resources; Cross-account role access is the more direct match.

Question 31

A learner is explaining Rehosting migration to colleagues facing this situation: a company wants to move an existing server-based application to AWS with minimal application changes. Which explanation is MOST accurate?

  1. Refactoring transforms the application architecture, rather than simply moving the existing runtime to the cloud.
  2. AWS Migration Hub provides visibility into discovered applications and migration activity across supported migration tools.
  3. Rehosting, often called lift and shift, relocates a workload without significant application redesign.
  4. Replatforming adjusts selected supporting components to gain cloud benefits without a full application rewrite.

Explanation

Correct Answer

C:

Rehosting, often called lift and shift, relocates a workload without significant application redesign. The explanation directly connects Rehosting migration to move the existing workload largely as-is to cloud infrastructure for the stated requirement.

Incorrect Answers

A:

This statement is true of Refactoring migration, which addresses a business is willing to redesign a tightly coupled application into cloud-native components. It does not explain the particular role of Rehosting migration; Rehosting, often called lift and shift, relocates a workload without significant application redesign.

B:

This statement is true of AWS Migration Hub, which addresses a program manager needs a consolidated place to follow the progress of multiple migration activities. It does not explain the particular role of Rehosting migration; Rehosting, often called lift and shift, relocates a workload without significant application redesign.

D:

This statement is true of Replatforming migration, which addresses a company moves an application to AWS and also adopts a managed database without rebuilding its business logic. It does not explain the particular role of Rehosting migration; Rehosting, often called lift and shift, relocates a workload without significant application redesign.

Question 32

A stakeholder is considering Temporary security credentials because a contractor needs access for a limited session without receiving a permanent AWS key. What is the MOST relevant capability or benefit?

  1. Require MFA for eligible AWS sign-in identities
  2. Examine resource access and policy exposure
  3. Manage shared user permissions
  4. Use expiring session credentials through an approved role or federation

Explanation

Correct Answer

D:

Use expiring session credentials through an approved role or federation. Short-lived credentials reduce the time a stolen credential can remain useful compared with persistent access keys. The stated need is specifically a contractor needs access for a limited session without receiving a permanent AWS key.

Incorrect Answers

A:

This outcome fits Multi-factor authentication: MFA requires another authentication factor beyond a password and reduces risks from compromised passwords. The stakeholder requires the more specific capability provided by Temporary security credentials, not that separate benefit.

B:

This outcome fits IAM Access Analyzer: Access Analyzer helps identify access findings; it does not by itself remove the underlying excessive permissions. The stakeholder requires the more specific capability provided by Temporary security credentials, not that separate benefit.

C:

This outcome fits IAM groups: IAM groups collect IAM users for permissions management; they are not assumed identities like IAM roles. The stakeholder requires the more specific capability provided by Temporary security credentials, not that separate benefit.

Question 33

Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: manage supported security policies centrally?

  1. AWS Firewall Manager
  2. AWS Knowledge Center
  3. Official AWS security documentation
  4. AWS Trusted Advisor

Explanation

Correct Answer

A:

AWS Firewall Manager directly addresses this outcome. Firewall Manager helps manage AWS WAF, Shield and related policies across an AWS Organizations environment. A common relevant example is: a security administrator needs consistent firewall policies across multiple AWS accounts.

Incorrect Answers

B:

AWS Knowledge Center instead focuses on a different requirement, such as an AWS user wants AWS-authored answers to common service troubleshooting and account questions. Knowledge Center provides guidance and answers; it is an information resource, not an active security enforcement tool. It is not the primary match for the requirement described here: manage supported security policies centrally.

C:

AWS Certified security documentation instead focuses on a different requirement, such as a governance team asks where to review public AWS security documentation and service compliance information. AWS official security and compliance pages provide reference material; the customer's own compliance assessment remains necessary. It is not the primary match for the requirement described here: manage supported security policies centrally.

D:

AWS Trusted Advisor security checks instead focuses on a different requirement, such as a small team wants to find certain common AWS account configuration risks through recommendations. Trusted Advisor provides best-practice guidance in supported categories including security, cost and service limits. It is not the primary match for the requirement described here: manage supported security policies centrally.

Question 34

A learner is explaining S3 Standard-IA to colleagues facing this situation: a business rarely accesses certain long-lived backup files but needs them rapidly when requested. Which explanation is MOST accurate?

  1. Deep Archive prioritizes low storage cost and accepts retrieval delays, unlike immediately accessed S3 classes.
  2. S3 Standard-IA has lower storage charges but access and minimum-duration considerations compared with frequently accessed classes.
  3. EFS is a managed elastic network file system for supported Linux workloads, unlike S3 object API storage.
  4. AWS Backup centralizes backup administration across supported resources; it is separate from normal object lifecycle transitions.

Explanation

Correct Answer

B:

S3 Standard-IA has lower storage charges but access and minimum-duration considerations compared with frequently accessed classes. The explanation directly connects S3 Standard-IA to use S3 Standard-IA for infrequently accessed objects with rapid access needs for the stated requirement.

Incorrect Answers

A:

This statement is true of S3 Glacier Deep Archive, which addresses a regulator requires long-term retention of records that will almost never be retrieved. It does not explain the particular role of S3 Standard-IA; S3 Standard-IA has lower storage charges but access and minimum-duration considerations compared with frequently accessed classes.

C:

This statement is true of Amazon EFS shared files, which addresses multiple Linux EC2 instances require a shared elastic file system supporting common file semantics. It does not explain the particular role of S3 Standard-IA; S3 Standard-IA has lower storage charges but access and minimum-duration considerations compared with frequently accessed classes.

D:

This statement is true of AWS Backup, which addresses a company needs centralized policies and visibility across supported AWS resource backups. It does not explain the particular role of S3 Standard-IA; S3 Standard-IA has lower storage charges but access and minimum-duration considerations compared with frequently accessed classes.

Question 35

A stakeholder is considering Security pillar because a business wants to protect data, identities, and systems while maintaining risk controls. What is the MOST relevant capability or benefit?

  1. Avoid unnecessary expense while delivering required outcomes
  2. Minimize energy consumption and environmental impact per unit of work
  3. Protect information and systems using risk-aware controls
  4. Represent infrastructure configuration declaratively and apply repeatable changes

Explanation

Correct Answer

C:

Protect information and systems using risk-aware controls. The Security pillar addresses identity, detection, infrastructure and data protection in the AWS Well-Architected Framework. The stated need is specifically a business wants to protect data, identities, and systems while maintaining risk controls.

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 Security pillar, not that separate benefit.

B:

This outcome fits Sustainability pillar: The Sustainability pillar encourages efficient resource use and reduced environmental impact of running workloads. The stakeholder requires the more specific capability provided by Security pillar, not that separate benefit.

D:

This outcome fits Infrastructure changes as code: Infrastructure as code reduces manual drift and supports consistent, reviewable infrastructure provisioning. The stakeholder requires the more specific capability provided by Security pillar, not that separate benefit.

Question 36

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

  1. A team wants an additional verification step if a user password is stolen
  2. A legacy automation application uses an AWS access-key ID and secret key for API access
  3. A security team wants to identify unintended external access to supported AWS resources
  4. A contractor needs access for a limited session without receiving a permanent AWS key

Explanation

Correct Answer

D:

The decisive requirement is: Use expiring session credentials through an approved role or federation. This is the role of Temporary security credentials. Short-lived credentials reduce the time a stolen credential can remain useful compared with persistent access keys.

Incorrect Answers

A:

This describes a scenario for Multi-factor authentication: require MFA for eligible AWS sign-in identities. MFA requires another authentication factor beyond a password and reduces risks from compromised passwords. It is not the most direct example of Temporary security credentials.

B:

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 Temporary security credentials.

C:

This describes a scenario for IAM Access Analyzer: use IAM Access Analyzer to examine resource access and policy exposure. Access Analyzer helps identify access findings; it does not by itself remove the underlying excessive permissions. It is not the most direct example of Temporary security credentials.

Question 37

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

  1. A legacy automation application uses an AWS access-key ID and secret key for API access
  2. A contractor needs access for a limited session without receiving a permanent AWS key
  3. A team wants an additional verification step if a user password is stolen
  4. An application needs temporary AWS credentials after assuming an authorized IAM role

Explanation

Correct Answer

A:

The decisive requirement is: Treat access keys as sensitive credentials and rotate or replace them where appropriate. This is the role of Access keys. AWS access keys enable programmatic authentication and must not be committed to public repositories.

Incorrect Answers

B:

This describes a scenario for Temporary security credentials: use expiring session credentials through an approved role or federation. Short-lived credentials reduce the time a stolen credential can remain useful compared with persistent access keys. It is not the most direct example of Access keys.

C:

This describes a scenario for Multi-factor authentication: require MFA for eligible AWS sign-in identities. MFA requires another authentication factor beyond a password and reduces risks from compromised passwords. It is not the most direct example of Access keys.

D:

This describes a scenario for AWS STS role assumption: obtain session credentials through AWS Security Token Service. STS provides temporary credentials for permitted role or federated sessions; it does not issue physical security tokens. It is not the most direct example of Access keys.

Question 38

A project manager compares IAM groups with other AWS concepts while considering this need: a team needs to assign the same AWS permissions to several IAM users. Which pairing assigns the responsibilities or benefits correctly?

  1. IAM groups: support application-user authentication and identity features; Amazon Cognito: manage shared user permissions
  2. IAM groups: manage shared user permissions; AWS Secrets Manager: meet this requirement: an application needs controlled storage and rotation of a database password
  3. IAM groups: provide temporary credentials to the workload; IAM roles: manage shared user permissions
  4. IAM groups: meet this requirement: an application needs controlled storage and rotation of a database password; AWS Secrets Manager: manage shared user permissions

Explanation

Correct Answer

B:

The first pairing identifies IAM groups with its actual role: use an IAM group to manage shared user permissions. IAM groups collect IAM users for permissions management; they are not assumed identities like IAM roles. The comparison is valid because AWS Secrets Manager instead addresses store and manage application secrets with AWS Secrets Manager.

Incorrect Answers

A:

The roles are swapped. Amazon Cognito is associated with use Amazon Cognito for application-user authentication and identity features; IAM groups instead has the role: Use an IAM group to manage shared user permissions. IAM groups collect IAM users for permissions management; they are not assumed identities like IAM roles.

C:

The roles are swapped. IAM roles is associated with use an IAM role to provide temporary credentials to the workload; IAM groups instead has the role: Use an IAM group to manage shared user permissions. IAM groups collect IAM users for permissions management; they are not assumed identities like IAM roles.

D:

The roles are swapped. AWS Secrets Manager is associated with store and manage application secrets with AWS Secrets Manager; IAM groups instead has the role: Use an IAM group to manage shared user permissions. IAM groups collect IAM users for permissions management; they are not assumed identities like IAM roles.

Question 39

A stakeholder is considering AWS Knowledge Center because an AWS user wants AWS-authored answers to common service troubleshooting and account questions. What is the MOST relevant capability or benefit?

  1. Enable supported cross-account resource sharing
  2. Meet this requirement: a company wants to evaluate a third-party security product compatible with AWS workloads
  3. Support documented guidance
  4. Find AWS-authored security and compliance guidance and assurance resources

Explanation

Correct Answer

C:

Use AWS Knowledge Center articles for documented guidance. Knowledge Center provides guidance and answers; it is an information resource, not an active security enforcement tool. The stated need is specifically an AWS user wants AWS-authored answers to common service troubleshooting and account questions.

Incorrect Answers

A:

This outcome fits AWS Resource Access Manager: AWS RAM manages sharing of eligible AWS resources with other accounts or organizational units, subject to permissions. The stakeholder requires the more specific capability provided by AWS Knowledge Center, not that separate benefit.

B:

This outcome fits AWS Marketplace security software: Marketplace lets customers discover and procure partner solutions; it is not the same as an AWS native security monitoring service. The stakeholder requires the more specific capability provided by AWS Knowledge Center, not that separate benefit.

D:

This outcome fits AWS Certified security documentation: AWS official security and compliance pages provide reference material; the customer's own compliance assessment remains necessary. The stakeholder requires the more specific capability provided by AWS Knowledge Center, not that separate benefit.

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.
