Question 1020

Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: use supported encrypted network connections such as TLS?

  1. Amazon Inspector
  2. AWS Organizations
  3. AWS Config
  4. Encryption in transit

Explanation

Correct Answer

D:

Encryption in transit directly addresses this outcome. Encryption in transit protects communications over networks; it differs from encryption of data stored on disks. A common relevant example is: a company wants to protect data while it moves between clients and an online service.

Incorrect Answers

A:

Amazon Inspector vulnerability findings instead focuses on a different requirement, such as an administrator wants continuous assessments of supported workloads for software vulnerabilities. Inspector identifies package and supported workload vulnerabilities; it is not a replacement for data classification. It is not the primary match for the requirement described here: use supported encrypted network connections such as TLS.

B:

AWS Organizations governance instead focuses on a different requirement, such as a company needs centralized governance across many separate AWS accounts. Organizations groups accounts and supports policies and billing consolidation; it does not itself analyze threats. It is not the primary match for the requirement described here: use supported encrypted network connections such as TLS.

C:

AWS Config resource history instead focuses on a different requirement, such as an organization must inspect how an AWS resource configuration changed over time. AWS Config tracks supported resource configuration history and rules rather than serving as a generic application log service. It is not the primary match for the requirement described here: use supported encrypted network connections such as TLS.

Question 1021

A project manager compares Amazon Redshift with other AWS concepts while considering this need: a data team needs a managed warehouse for analytical SQL queries across large structured datasets. Which pairing assigns the responsibilities or benefits correctly?

  1. Amazon Redshift: support cloud data warehousing; Amazon ElastiCache: support managed in-memory caching
  2. Amazon Redshift: enable supported relational engines; Amazon RDS: support cloud data warehousing
  3. Amazon Redshift: support managed in-memory caching; Amazon ElastiCache: support cloud data warehousing
  4. Amazon Redshift: support database transfer and applicable ongoing replication; AWS Database Migration Service: support cloud data warehousing

Explanation

Correct Answer

A:

The first pairing identifies Amazon Redshift with its actual role: use Amazon Redshift for cloud data warehousing. Redshift is designed for analytics and data warehousing rather than being a low-latency transactional key-value store. The comparison is valid because Amazon ElastiCache instead addresses use Amazon ElastiCache for managed in-memory caching.

Incorrect Answers

B:

The roles are swapped. Amazon RDS is associated with use Amazon Relational Database Service for supported relational engines; Amazon Redshift instead has the role: Use Amazon Redshift for cloud data warehousing. Redshift is designed for analytics and data warehousing rather than being a low-latency transactional key-value store.

C:

The roles are swapped. Amazon ElastiCache is associated with use Amazon ElastiCache for managed in-memory caching; Amazon Redshift instead has the role: Use Amazon Redshift for cloud data warehousing. Redshift is designed for analytics and data warehousing rather than being a low-latency transactional key-value store.

D:

The roles are swapped. AWS Database Migration Service is associated with use AWS DMS for database transfer and applicable ongoing replication; Amazon Redshift instead has the role: Use Amazon Redshift for cloud data warehousing. Redshift is designed for analytics and data warehousing rather than being a low-latency transactional key-value store.

Question 1022

A learner is explaining AWS Resource Access Manager to colleagues facing this situation: two AWS accounts in one organization need to share supported resources without duplicating them. Which explanation is MOST accurate?

  1. AWS security guidance supports safe decisions, while controls still need deliberate configuration by the customer.
  2. AWS RAM manages sharing of eligible AWS resources with other accounts or organizational units, subject to permissions.
  3. AWS official security and compliance pages provide reference material; the customer's own compliance assessment remains necessary.
  4. Detective correlates supported signals for investigation; GuardDuty focuses on finding potential threats.

Explanation

Correct Answer

B:

AWS RAM manages sharing of eligible AWS resources with other accounts or organizational units, subject to permissions. The explanation directly connects AWS Resource Access Manager to use AWS Resource Access Manager for supported cross-account resource sharing for the stated requirement.

Incorrect Answers

A:

This statement is true of AWS security best practices, which addresses an organization needs general recommendations to harden AWS workloads. It does not explain the particular role of AWS Resource Access Manager; AWS RAM manages sharing of eligible AWS resources with other accounts or organizational units, subject to permissions.

C:

This statement is true of AWS Certified security documentation, which addresses a governance team asks where to review public AWS security documentation and service compliance information. It does not explain the particular role of AWS Resource Access Manager; AWS RAM manages sharing of eligible AWS resources with other accounts or organizational units, subject to permissions.

D:

This statement is true of Amazon Detective investigations, which addresses an analyst wants to investigate relationships among security findings after suspicious activity is detected. It does not explain the particular role of AWS Resource Access Manager; AWS RAM manages sharing of eligible AWS resources with other accounts or organizational units, subject to permissions.

Question 1023

Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: represent infrastructure configuration declaratively and apply repeatable changes?

  1. Measure outcomes
  2. Operational Excellence pillar
  3. Infrastructure changes as code
  4. Reliability pillar

Explanation

Correct Answer

C:

Infrastructure changes as code directly addresses this outcome. Infrastructure as code reduces manual drift and supports consistent, reviewable infrastructure provisioning. A common relevant example is: a team repeatedly creates similar environments and wants changes that can be reviewed and reproduced.

Incorrect Answers

A:

Measure outcomes instead focuses on a different requirement, such as a cloud team cannot tell whether a change improved customer-facing performance. The Well-Architected approach encourages observing real workload outcomes rather than relying only on resource existence. It is not the primary match for the requirement described here: represent infrastructure configuration declaratively and apply repeatable changes.

B:

Operational Excellence pillar instead focuses on a different requirement, such as a team wants to improve routine operations through measurement, incident learning, and repeatable processes. The Operational Excellence pillar focuses on running and monitoring workloads effectively and improving operational processes. It is not the primary match for the requirement described here: represent infrastructure configuration declaratively and apply repeatable changes.

D:

Reliability pillar instead focuses on a different requirement, such as an application needs to recover predictably from failures and adapt when demand changes. The Reliability pillar emphasizes recovery, distributed design, and meeting availability requirements. It is not the primary match for the requirement described here: represent infrastructure configuration declaratively and apply repeatable changes.

Question 1024

Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: assist security investigations?

  1. Official AWS security documentation
  2. AWS WAF application protection
  3. AWS security best practices
  4. Amazon Detective

Explanation

Correct Answer

D:

Amazon Detective directly addresses this outcome. Detective correlates supported signals for investigation; GuardDuty focuses on finding potential threats. A common relevant example is: an analyst wants to investigate relationships among security findings after suspicious activity is detected.

Incorrect Answers

A:

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: assist security investigations.

B:

AWS WAF application protection instead focuses on a different requirement, such as a public website needs rules to inspect common malicious HTTP requests. WAF acts at web request level and can help mitigate common HTTP attack patterns. It is not the primary match for the requirement described here: assist security investigations.

C:

AWS security best practices instead focuses on a different requirement, such as an organization needs general recommendations to harden AWS workloads. AWS security guidance supports safe decisions, while controls still need deliberate configuration by the customer. It is not the primary match for the requirement described here: assist security investigations.

Question 1025

Within the Cloud Technology and Services domain, which business example MOST clearly illustrates AWS service APIs, rather than a different AWS concept?

  1. A system needs a programmatic interface to request and manage AWS resources
  2. A developer wants a Java application to interact with AWS services using language libraries
  3. A bank must keep some applications on its own premises while using AWS for other services
  4. A manufacturer needs AWS-managed hardware and selected cloud services in its own facility

Explanation

Correct Answer

A:

The decisive requirement is: Interact with AWS services through supported API operations. This is the role of AWS service APIs. AWS APIs enable programmatic service access; management consoles and SDKs are other ways to use such capabilities.

Incorrect Answers

B:

This describes a scenario for AWS SDKs: use an AWS SDK to call service APIs from application code. AWS SDKs provide language-specific APIs and tooling for integrating application software with AWS. It is not the most direct example of AWS service APIs.

C:

This describes a scenario for Hybrid cloud deployment: 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. It is not the most direct example of AWS service APIs.

D:

This describes a scenario for AWS Outposts: use AWS Outposts for supported AWS infrastructure placed on premises. Outposts extends supported AWS infrastructure and services to customer locations where local processing or data needs apply. It is not the most direct example of AWS service APIs.

Question 1026

A developer chooses Amazon RDS instead of installing a database engine on an EC2 virtual machine. Which AWS service or cloud concept is the MOST direct match for this need?

  1. Customer encryption choices
  2. AWS RDS database infrastructure
  3. Customer IAM permissions
  4. Customer data classification

Explanation

Correct Answer

B:

AWS RDS database infrastructure fits the need because rDS reduces operational work compared with a self-managed database, but does not remove customer responsibilities for data and access. The relevant capability or responsibility is: AWS performs managed database infrastructure tasks such as underlying host and OS maintenance.

Incorrect Answers

A:

Customer encryption choices is associated with a different use case: a company wants to ensure its application stores sensitive objects with required encryption settings. Managed services can provide encryption capabilities, but customers must select and govern settings needed for their data. The question instead focuses on a developer chooses Amazon RDS instead of installing a database engine on an EC2 virtual machine; AWS RDS database infrastructure is the more direct match.

C:

Customer IAM permissions is associated with a different use case: an organization must decide which employees can read an S3 bucket in its AWS account. Even on a managed AWS service, customers remain responsible for authorizing who can access their data. The question instead focuses on a developer chooses Amazon RDS instead of installing a database engine on an EC2 virtual machine; AWS RDS database infrastructure is the more direct match.

D:

Customer data classification is associated with a different use case: a regulated company must identify which of its uploaded records contain sensitive personal information. AWS cannot determine the business sensitivity of customer content; data classification and applicable handling policies belong to the customer. The question instead focuses on a developer chooses Amazon RDS instead of installing a database engine on an EC2 virtual machine; AWS RDS database infrastructure is the more direct match.

Question 1027

A stakeholder is considering Infrastructure changes as code because a team repeatedly creates similar environments and wants changes that can be reviewed and reproduced. What is the MOST relevant capability or benefit?

  1. Exercise recovery procedures to validate assumptions
  2. Recover from disruptions and perform the intended function consistently
  3. Represent infrastructure configuration declaratively and apply repeatable changes
  4. Use automation for routine, repeatable operational actions

Explanation

Correct Answer

C:

Represent infrastructure configuration declaratively and apply repeatable changes. Infrastructure as code reduces manual drift and supports consistent, reviewable infrastructure provisioning. The stated need is specifically a team repeatedly creates similar environments and wants changes that can be reviewed and reproduced.

Incorrect Answers

A:

This outcome fits Test recovery assumptions: Regular recovery testing reveals gaps in backup, dependency, and restoration plans before a real disruption. The stakeholder requires the more specific capability provided by Infrastructure changes as code, not that separate benefit.

B:

This outcome fits Reliability pillar: The Reliability pillar emphasizes recovery, distributed design, and meeting availability requirements. The stakeholder requires the more specific capability provided by Infrastructure changes as code, not that separate benefit.

D:

This outcome fits Automated operational response: Automating repeatable operations reduces manual error and supports dependable responses while human review remains appropriate for sensitive changes. The stakeholder requires the more specific capability provided by Infrastructure changes as code, not that separate benefit.

Question 1028

A learner is explaining On-Demand Capacity Reservations to colleagues facing this situation: a business needs assurance that EC2 capacity will be available in a chosen Availability Zone for a planned event. Which explanation is MOST accurate?

  1. On-Demand pricing gives flexible capacity for irregular or new workloads, generally without the discounts of eligible commitments.
  2. EC2 Spot Instances offer discounted unused capacity but can be reclaimed with interruption notices.
  3. Reserved Instances offer pricing benefits for qualifying EC2 usage with a term commitment and specified attributes.
  4. An On-Demand Capacity Reservation addresses EC2 capacity availability rather than by itself providing a commitment pricing reduction.

Explanation

Correct Answer

D:

An On-Demand Capacity Reservation addresses EC2 capacity availability rather than by itself providing a commitment pricing reduction. The explanation directly connects On-Demand Capacity Reservations to reserve eligible compute capacity without necessarily purchasing a usage discount for the stated requirement.

Incorrect Answers

A:

This statement is true of On-Demand EC2 pricing, which addresses a company needs compute capacity for a short unpredictable project and does not want a long commitment. It does not explain the particular role of On-Demand Capacity Reservations; An On-Demand Capacity Reservation addresses EC2 capacity availability rather than by itself providing a commitment pricing reduction.

B:

This statement is true of Spot Instances, which addresses a research team runs flexible batch processing jobs that can tolerate interruption. It does not explain the particular role of On-Demand Capacity Reservations; An On-Demand Capacity Reservation addresses EC2 capacity availability rather than by itself providing a commitment pricing reduction.

C:

This statement is true of Reserved Instances, which addresses an enterprise runs a predictable EC2 workload and can make a qualifying commitment. It does not explain the particular role of On-Demand Capacity Reservations; An On-Demand Capacity Reservation addresses EC2 capacity availability rather than by itself providing a commitment pricing reduction.

Question 1029

A stakeholder is considering AWS Resource Access Manager because two AWS accounts in one organization need to share supported resources without duplicating them. What is the MOST relevant capability or benefit?

  1. Enable supported cross-account resource sharing
  2. Meet this requirement: a small team wants to find certain common AWS account configuration risks through recommendations
  3. Support DDoS protection capabilities
  4. Support documented guidance

Explanation

Correct Answer

A:

Use AWS Resource Access Manager for supported cross-account resource sharing. AWS RAM manages sharing of eligible AWS resources with other accounts or organizational units, subject to permissions. The stated need is specifically two AWS accounts in one organization need to share supported resources without duplicating them.

Incorrect Answers

B:

This outcome fits AWS Trusted Advisor security checks: Trusted Advisor provides best-practice guidance in supported categories including security, cost and service limits. The stakeholder requires the more specific capability provided by AWS Resource Access Manager, not that separate benefit.

C:

This outcome fits AWS Shield DDoS protection: Shield provides managed DDoS protection rather than classifying sensitive objects or managing IAM identities. The stakeholder requires the more specific capability provided by AWS Resource Access Manager, not that separate benefit.

D:

This outcome fits AWS Knowledge Center: Knowledge Center provides guidance and answers; it is an information resource, not an active security enforcement tool. The stakeholder requires the more specific capability provided by AWS Resource Access Manager, not that separate benefit.

Question 1030

A learner is explaining AWS Shield to colleagues facing this situation: a public application is concerned about distributed denial-of-service traffic. Which explanation is MOST accurate?

  1. AWS RAM manages sharing of eligible AWS resources with other accounts or organizational units, subject to permissions.
  2. Shield provides managed DDoS protection rather than classifying sensitive objects or managing IAM identities.
  3. AWS's official security blog explains security topics, unlike a service that enforces network traffic filtering.
  4. Detective correlates supported signals for investigation; GuardDuty focuses on finding potential threats.

Explanation

Correct Answer

B:

Shield provides managed DDoS protection rather than classifying sensitive objects or managing IAM identities. The explanation directly connects AWS Shield to use AWS Shield for DDoS protection capabilities for the stated requirement.

Incorrect Answers

A:

This statement is true of AWS Resource Access Manager, which addresses two AWS accounts in one organization need to share supported resources without duplicating them. It does not explain the particular role of AWS Shield; Shield provides managed DDoS protection rather than classifying sensitive objects or managing IAM identities.

C:

This statement is true of AWS Security Blog guidance, which addresses security engineers want AWS-authored technical articles discussing security practices. It does not explain the particular role of AWS Shield; Shield provides managed DDoS protection rather than classifying sensitive objects or managing IAM identities.
