Question 140

An application must remain available if one Availability Zone experiences an outage. Which AWS service or cloud concept is the MOST direct match for this need?

  1. AWS Global Accelerator
  2. AWS Region
  3. Data sovereignty Region choice
  4. Multiple Availability Zones

Explanation

Correct Answer

D:

Multiple Availability Zones fits the need because multi-AZ deployments can avoid a single-AZ failure taking down the whole application. The relevant capability or responsibility is: Place redundant application components across different AZs within a Region.

Incorrect Answers

A:

AWS Global Accelerator is associated with a different use case: an internet-facing app has regional endpoints and needs stable global entry points for traffic routing. Global Accelerator provides static anycast IP addresses and routes traffic over the AWS global network to healthy endpoints. The question instead focuses on an application must remain available if one Availability Zone experiences an outage; Multiple Availability Zones is the more direct match.

B:

AWS Region is associated with a different use case: a company is selecting a separate geographic AWS location for a workload with residency requirements. A Region is a geographically separate area containing multiple Availability Zones; customers select deployment Regions. The question instead focuses on an application must remain available if one Availability Zone experiences an outage; Multiple Availability Zones is the more direct match.

C:

Data sovereignty Region choice is associated with a different use case: a government customer requires that certain datasets be stored in a specified legal jurisdiction. Region choice is a customer decision for residency compliance, subject to service availability and contractual requirements. The question instead focuses on an application must remain available if one Availability Zone experiences an outage; Multiple Availability Zones is the more direct match.

Question 141

A stakeholder is considering Amazon Lightsail because a small business wants a straightforward virtual private server with bundled resources. What is the MOST relevant capability or benefit?

  1. Support simplified cloud hosting
  2. Meet this requirement: an analytics node needs high local disk throughput for temporary data processing
  3. Support configurable virtual compute instances
  4. Support AWS-hosted Kubernetes orchestration

Explanation

Correct Answer

A:

Use Amazon Lightsail for simplified cloud hosting. Lightsail offers simple virtual server and related resource plans for common small applications and websites. The stated need is specifically a small business wants a straightforward virtual private server with bundled resources.

Incorrect Answers

B:

This outcome fits Storage-optimized EC2: Storage-optimized instance families are designed for high local storage I/O and throughput needs. The stakeholder requires the more specific capability provided by Amazon Lightsail, not that separate benefit.

C:

This outcome fits Amazon EC2 virtual servers: EC2 offers virtual servers with selectable instance types and customer-managed guest operating systems. The stakeholder requires the more specific capability provided by Amazon Lightsail, not that separate benefit.

D:

This outcome fits Amazon EKS: EKS offers managed Kubernetes control-plane capabilities for applications using Kubernetes APIs. The stakeholder requires the more specific capability provided by Amazon Lightsail, not that separate benefit.

Question 142

Within the Cloud Concepts domain, which business example MOST clearly illustrates On-demand provisioning, rather than a different AWS concept?

  1. Several departments need separate virtual workloads without each purchasing dedicated physical machines
  2. A testing team needs temporary computing capacity immediately for a newly approved project
  3. A seasonal nonprofit wants computing only during a two-week annual campaign
  4. A hospital booking service must remain accessible even when one hosting location becomes unavailable

Explanation

Correct Answer

B:

The decisive requirement is: Provision capacity when requested rather than waiting for hardware ordering. This is the role of On-demand provisioning. AWS self-service resource provisioning reduces procurement lead time for many workloads.

Incorrect Answers

A:

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 On-demand provisioning.

C:

This describes a scenario for Pay-as-you-go consumption: pay for consumed services instead of buying hardware for the annual peak. Usage-based cloud charging can reduce upfront investment and better match cost to periods of actual consumption. It is not the most direct example of On-demand provisioning.

D:

This describes a scenario for High availability: keep the application accessible by using redundant resources and eliminating single points of failure. High availability focuses on minimizing service interruptions through redundancy and service continuity. It is not the most direct example of On-demand provisioning.

Question 143

A project manager compares Consolidated billing with other AWS concepts while considering this need: a company wants a centralized bill and eligible aggregated charges from multiple AWS accounts. Which pairing assigns the responsibilities or benefits correctly?

  1. Consolidated billing: meet this requirement: a new learner wants to understand eligible introductory usage offers and their limits; AWS Free Tier: meet this requirement: a company wants a centralized bill and eligible aggregated charges from multiple AWS accounts
  2. Consolidated billing: support detailed cost and consumption data; AWS Cost and Usage Report: meet this requirement: a company wants a centralized bill and eligible aggregated charges from multiple AWS accounts
  3. Consolidated billing: meet this requirement: a company wants a centralized bill and eligible aggregated charges from multiple AWS accounts; AWS Pricing Calculator: support planned service cost estimates
  4. Consolidated billing: support planned service cost estimates; AWS Pricing Calculator: meet this requirement: a company wants a centralized bill and eligible aggregated charges from multiple AWS accounts

Explanation

Correct Answer

C:

The first pairing identifies Consolidated billing with its actual role: use AWS Organizations consolidated billing across eligible member accounts. Consolidated billing combines eligible charges and payment across AWS Organizations accounts while accounts remain logically distinct. The comparison is valid because AWS Pricing Calculator instead addresses use AWS Pricing Calculator for planned service cost estimates.

Incorrect Answers

A:

The roles are swapped. AWS Free Tier is associated with review the AWS Free Tier terms and eligible service offers before launching resources; Consolidated billing instead has the role: Use AWS Organizations consolidated billing across eligible member accounts. Consolidated billing combines eligible charges and payment across AWS Organizations accounts while accounts remain logically distinct.

B:

The roles are swapped. AWS Cost and Usage Report is associated with use AWS Cost and Usage Reports for detailed cost and consumption data; Consolidated billing instead has the role: Use AWS Organizations consolidated billing across eligible member accounts. Consolidated billing combines eligible charges and payment across AWS Organizations accounts while accounts remain logically distinct.

D:

The roles are swapped. AWS Pricing Calculator is associated with use AWS Pricing Calculator for planned service cost estimates; Consolidated billing instead has the role: Use AWS Organizations consolidated billing across eligible member accounts. Consolidated billing combines eligible charges and payment across AWS Organizations accounts while accounts remain logically distinct.

Question 144

A project manager compares EC2 instance store with other AWS concepts while considering this need: a rendering workload needs high-performance temporary local scratch data that may be lost with its instance. Which pairing assigns the responsibilities or benefits correctly?

  1. EC2 instance store: support very rarely accessed long-term archival data; S3 Glacier Deep Archive: support eligible ephemeral EC2 local storage
  2. EC2 instance store: support scalable object storage; Amazon S3: support eligible ephemeral EC2 local storage
  3. EC2 instance store: bridge local storage access to AWS; AWS Storage Gateway: support eligible ephemeral EC2 local storage
  4. EC2 instance store: support eligible ephemeral EC2 local storage; Amazon S3: support scalable object storage

Explanation

Correct Answer

D:

The first pairing identifies EC2 instance store with its actual role: use instance store for eligible ephemeral EC2 local storage. Instance store provides temporary local storage whose data does not have the durability properties of an EBS volume. The comparison is valid because Amazon S3 object storage instead addresses use Amazon S3 for scalable object storage.

Incorrect Answers

A:

The roles are swapped. S3 Glacier Deep Archive is associated with use S3 Glacier Deep Archive for very rarely accessed long-term archival data; EC2 instance store instead has the role: Use instance store for eligible ephemeral EC2 local storage. Instance store provides temporary local storage whose data does not have the durability properties of an EBS volume.

B:

The roles are swapped. Amazon S3 is associated with use Amazon S3 for scalable object storage; EC2 instance store instead has the role: Use instance store for eligible ephemeral EC2 local storage. Instance store provides temporary local storage whose data does not have the durability properties of an EBS volume.

C:

The roles are swapped. AWS Storage Gateway is associated with use AWS Storage Gateway to bridge local storage access to AWS; EC2 instance store instead has the role: Use instance store for eligible ephemeral EC2 local storage. Instance store provides temporary local storage whose data does not have the durability properties of an EBS volume.

Question 145

A learner is explaining AWS WAF application protection to colleagues facing this situation: a public website needs rules to inspect common malicious HTTP requests. Which explanation is MOST accurate?

  1. WAF acts at web request level and can help mitigate common HTTP attack patterns.
  2. Trusted Advisor provides best-practice guidance in supported categories including security, cost and service limits.
  3. AWS's official security blog explains security topics, unlike a service that enforces network traffic filtering.
  4. Knowledge Center provides guidance and answers; it is an information resource, not an active security enforcement tool.

Explanation

Correct Answer

A:

WAF acts at web request level and can help mitigate common HTTP attack patterns. The explanation directly connects AWS WAF application protection to use AWS WAF to filter supported web requests for the stated requirement.

Incorrect Answers

B:

This statement is true of AWS Trusted Advisor security checks, which addresses a small team wants to find certain common AWS account configuration risks through recommendations. It does not explain the particular role of AWS WAF application protection; WAF acts at web request level and can help mitigate common HTTP attack patterns.

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 WAF application protection; WAF acts at web request level and can help mitigate common HTTP attack patterns.

D:

This statement is true of AWS Knowledge Center, which addresses an AWS user wants AWS-authored answers to common service troubleshooting and account questions. It does not explain the particular role of AWS WAF application protection; WAF acts at web request level and can help mitigate common HTTP attack patterns.

Question 146

A learner is explaining Business continuity to colleagues facing this situation: a retailer needs a plan for resuming critical operations after a major disruption. Which explanation is MOST accurate?

  1. Elasticity aligns live capacity with changing workload demand so idle peak-sized resources do not remain continuously allocated.
  2. Business continuity combines preparedness and recovery measures rather than assuming failures will never occur.
  3. AWS self-service resource provisioning reduces procurement lead time for many workloads.
  4. AWS Regions enable deployment in multiple geographies without building and operating a physical data center in each market.

Explanation

Correct Answer

B:

Business continuity combines preparedness and recovery measures rather than assuming failures will never occur. The explanation directly connects Business continuity to plan for sustained essential operations and recovery after disruptive events for the stated requirement.

Incorrect Answers

A:

This statement is true of Elasticity, which addresses an online store has unpredictable weekend traffic spikes followed by quiet weekdays. It does not explain the particular role of Business continuity; Business continuity combines preparedness and recovery measures rather than assuming failures will never occur.

C:

This statement is true of On-demand provisioning, which addresses a testing team needs temporary computing capacity immediately for a newly approved project. It does not explain the particular role of Business continuity; Business continuity combines preparedness and recovery measures rather than assuming failures will never occur.

D:

This statement is true of Global reach, which addresses a software provider wants to serve customers from multiple continents without building overseas data centers. It does not explain the particular role of Business continuity; Business continuity combines preparedness and recovery measures rather than assuming failures will never occur.

Question 147

A stakeholder is considering Customer RDS data permissions because an RDS database stores sensitive customer records and must restrict user privileges. What is the MOST relevant capability or benefit?

  1. The customer chooses applicable encryption configuration and key-access policies
  2. AWS maintains the physical host and underlying cloud virtualization infrastructure
  3. The customer configures database users and permissions for its application data
  4. Customer operational responsibilities generally decrease as more service layers become AWS-managed

Explanation

Correct Answer

C:

The customer configures database users and permissions for its application data. Selecting a managed database does not transfer responsibility for customer identities and data authorization to AWS. The stated need is specifically an RDS database stores sensitive customer records and must restrict user privileges.

Incorrect Answers

A:

This outcome fits Customer encryption choices: Managed services can provide encryption capabilities, but customers must select and govern settings needed for their data. The stakeholder requires the more specific capability provided by Customer RDS data permissions, not that separate benefit.

B:

This outcome fits AWS EC2 host infrastructure: AWS is responsible for facilities, physical servers and underlying cloud infrastructure for EC2. The stakeholder requires the more specific capability provided by Customer RDS data permissions, not that separate benefit.

D:

This outcome fits Shared responsibility varies by service: Responsibility depends on the service model: managing an EC2 guest OS differs from managing application code on Lambda. The stakeholder requires the more specific capability provided by Customer RDS data permissions, not that separate benefit.

Question 148

Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: meet this requirement: a small team wants to find certain common AWS account configuration risks through recommendations?

  1. Official AWS security documentation
  2. AWS Firewall Manager
  3. AWS Security Blog guidance
  4. AWS Trusted Advisor

Explanation

Correct Answer

D:

AWS Trusted Advisor directly addresses this outcome. Trusted Advisor provides best-practice guidance in supported categories including security, cost and service limits. A common relevant example is: a small team wants to find certain common AWS account configuration risks through recommendations.

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: meet this requirement: a small team wants to find certain common AWS account configuration risks through recommendations.

B:

AWS Firewall Manager policy oversight instead focuses on a different requirement, such as a security administrator needs consistent firewall policies across multiple AWS accounts. Firewall Manager helps manage AWS WAF, Shield and related policies across an AWS Organizations environment. It is not the primary match for the requirement described here: meet this requirement: a small team wants to find certain common AWS account configuration risks through recommendations.

C:

AWS Security Blog guidance instead focuses on a different requirement, such as security engineers want AWS-authored technical articles discussing security practices. AWS's official security blog explains security topics, unlike a service that enforces network traffic filtering. It is not the primary match for the requirement described here: meet this requirement: a small team wants to find certain common AWS account configuration risks through recommendations.

Question 149

A learner is explaining Customer IAM permissions to colleagues facing this situation: an organization must decide which employees can read an S3 bucket in its AWS account. Which explanation is MOST accurate?

  1. Even on a managed AWS service, customers remain responsible for authorizing who can access their data.
  2. Serverless eliminates server administration for the customer, not their responsibility for their own application code and data handling.
  3. RDS reduces operational work compared with a self-managed database, but does not remove customer responsibilities for data and access.
  4. Physical facility access controls and provider-owned hardware protection fall under AWS security of the cloud.

Explanation

Correct Answer

A:

Even on a managed AWS service, customers remain responsible for authorizing who can access their data. The explanation directly connects Customer IAM permissions to the customer configures identity permissions for access to its own data for the stated requirement.

Incorrect Answers

B:

This statement is true of Customer Lambda function code, which addresses a Lambda function processes user data using application code written by a development team. It does not explain the particular role of Customer IAM permissions; Even on a managed AWS service, customers remain responsible for authorizing who can access their data.

C:

This statement is true of AWS RDS database infrastructure, which addresses a developer chooses Amazon RDS instead of installing a database engine on an EC2 virtual machine. It does not explain the particular role of Customer IAM permissions; Even on a managed AWS service, customers remain responsible for authorizing who can access their data.

D:

This statement is true of AWS physical data center security, which addresses an AWS customer asks who guards the buildings where AWS runs underlying server hardware. It does not explain the particular role of Customer IAM permissions; Even on a managed AWS service, customers remain responsible for authorizing who can access their data.

Question 150

A stakeholder is considering AWS Budgets because a project manager wants an alert when forecast monthly cloud spending will exceed a set threshold. What is the MOST relevant capability or benefit?

  1. Support rule-based business cost groupings
  2. Track spending or usage against defined budget thresholds
  3. Attribute cloud spending to business units through approved resource labels
  4. Support detailed cost and consumption data

Explanation

Correct Answer

B:

Use AWS Budgets to track spending or usage against defined budget thresholds. Budgets supports cost and usage alerts relative to planned thresholds; it is distinct from an invoice payment processor. The stated need is specifically a project manager wants an alert when forecast monthly cloud spending will exceed a set threshold.

Incorrect Answers

A:

This outcome fits Cost Categories: Cost Categories organizes cost and usage data into custom business categories using defined rules. The stakeholder requires the more specific capability provided by AWS Budgets, not that separate benefit.

C:

This outcome fits Cost allocation tags: Cost allocation tags help group eligible charges by tagged resources after activation and appropriate billing data collection. The stakeholder requires the more specific capability provided by AWS Budgets, not that separate benefit.

D:

This outcome fits AWS Cost and Usage Report: Cost and Usage Reports provide detailed charge records suitable for custom analysis rather than just high-level charts. The stakeholder requires the more specific capability provided by AWS Budgets, not that separate benefit.
