Question 260
A stakeholder is considering AWS SDKs because a developer wants a Java application to interact with AWS services using language libraries. What is the MOST relevant capability or benefit?
- Support infrastructure as code provisioning
- Enable supported AWS infrastructure placed on premises
- Meet this requirement: a business analyst occasionally needs to view AWS resources through a browser interface
- Call service APIs from application code
Explanation
Correct Answer
D: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. The stated need is specifically a developer wants a Java application to interact with AWS services using language libraries.
Incorrect Answers
A:This outcome fits AWS CloudFormation: CloudFormation uses templates and stacks to create and manage supported AWS resources consistently. The stakeholder requires the more specific capability provided by AWS SDKs, not that separate benefit.
B:This outcome fits AWS Outposts: Outposts extends supported AWS infrastructure and services to customer locations where local processing or data needs apply. The stakeholder requires the more specific capability provided by AWS SDKs, not that separate benefit.
C: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 AWS SDKs, not that separate benefit.
Question 261
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: support CPU-heavy work?
- Compute-optimized EC2
- Amazon Lightsail
- Amazon EC2
- AWS Lambda
Explanation
Correct Answer
A:Compute-optimized EC2 directly addresses this outcome. Compute-optimized instances provide a high ratio of compute performance for suitable CPU-bound applications. A common relevant example is: a simulation workload spends most of its time performing CPU-intensive numerical calculations.
Incorrect Answers
B:Amazon Lightsail instead focuses on a different requirement, such as a small business wants a straightforward virtual private server with bundled resources. Lightsail offers simple virtual server and related resource plans for common small applications and websites. It is not the primary match for the requirement described here: support CPU-heavy work.
C: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 CPU-heavy work.
D: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 CPU-heavy work.
Question 262
Within the Security and Compliance domain, which business example MOST clearly illustrates AWS Security Hub, rather than a different AWS concept?
- A team needs to discover potentially sensitive information stored within Amazon S3
- A security operations team wants a consolidated view of findings from multiple AWS security services
- A regulated company assumes AWS compliance certificates automatically satisfy every customer-specific obligation
- A company needs centralized governance across many separate AWS accounts
Explanation
Correct Answer
B:The decisive requirement is: Aggregate and prioritize security findings with AWS Security Hub. This is the role of AWS Security Hub. Security Hub centralizes security posture information and findings rather than storing application business data.
Incorrect Answers
A:This describes a scenario for Amazon Macie sensitive S3 data: use Amazon Macie to detect and classify sensitive S3 data. Macie uses managed data discovery to help identify sensitive information in S3 objects, not network packet attacks. It is not the most direct example of AWS Security Hub.
C:This describes a scenario for AWS compliance shared model: evaluate customer controls and obligations alongside AWS's assurance documentation. AWS compliance programs cover AWS's side of applicable frameworks, while customers must evaluate and satisfy their own duties. It is not the most direct example of AWS Security Hub.
D:This describes a scenario for AWS Organizations governance: use AWS Organizations for multi-account governance and consolidated controls. Organizations groups accounts and supports policies and billing consolidation; it does not itself analyze threats. It is not the most direct example of AWS Security Hub.
Question 263
Within the Cloud Technology and Services domain, which business example MOST clearly illustrates Amazon SNS, rather than a different AWS concept?
- A company must send transactional confirmation emails from its application
- A SaaS app emits business events that must be routed to different AWS targets based on rules
- A monitoring event should send notifications to multiple subscribed endpoints
- A business process needs a coordinated sequence of several AWS service tasks with branching states
Explanation
Correct Answer
C:The decisive requirement is: Use Amazon SNS for publish-subscribe notifications and fan-out. This is the role of Amazon SNS. SNS distributes published messages to subscribed destinations; it is not a relational database.
Incorrect Answers
A:This describes a scenario for Amazon SES: use Amazon Simple Email Service for application email delivery. SES provides email sending and related features for business application communications. It is not the most direct example of Amazon SNS.
B:This describes a scenario for Amazon EventBridge: use Amazon EventBridge for event bus routing and integration. EventBridge matches events against rules and directs them to supported targets. It is not the most direct example of Amazon SNS.
D:This describes a scenario for AWS Step Functions: use AWS Step Functions for managed workflow orchestration. Step Functions models stateful application workflows and service coordination rather than storing the business records. It is not the most direct example of Amazon SNS.
Question 264
A stakeholder is considering Amazon Detective because an analyst wants to investigate relationships among security findings after suspicious activity is detected. What is the MOST relevant capability or benefit?
- Meet this requirement: a company wants to evaluate a third-party security product compatible with AWS workloads
- Enable supported cross-account resource sharing
- Find AWS-authored security and compliance guidance and assurance resources
- Assist security investigations
Explanation
Correct Answer
D:Use Amazon Detective to assist security investigations. Detective correlates supported signals for investigation; GuardDuty focuses on finding potential threats. The stated need is specifically an analyst wants to investigate relationships among security findings after suspicious activity is detected.
Incorrect Answers
A: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 Amazon Detective, not that separate benefit.
B: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 Amazon Detective, not that separate benefit.
C: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 Amazon Detective, not that separate benefit.
Question 265
A learner is explaining Amazon VPC to colleagues facing this situation: a team wants a logically isolated network environment for its AWS compute resources. Which explanation is MOST accurate?
- A VPC is a logically isolated virtual network in which customers can organize subnets, routes and connectivity.
- Site-to-Site VPN provides encrypted tunnels using internet-based connectivity, subject to supported gateway arrangements.
- Security groups control permitted traffic for associated resources and automatically allow response traffic to allowed flows.
- Transit Gateway acts as a regional routing hub for supported VPC and network attachments.
Explanation
Correct Answer
A:A VPC is a logically isolated virtual network in which customers can organize subnets, routes and connectivity. The explanation directly connects Amazon VPC to use Amazon Virtual Private Cloud for customer-defined virtual networking for the stated requirement.
Incorrect Answers
B:This statement is true of AWS Site-to-Site VPN, which addresses a company wants an encrypted tunnel between an office network and its AWS VPC over the internet. It does not explain the particular role of Amazon VPC; A VPC is a logically isolated virtual network in which customers can organize subnets, routes and connectivity.
C:This statement is true of Security groups, which addresses an EC2 workload should allow only specified inbound and outbound connections at the resource level. It does not explain the particular role of Amazon VPC; A VPC is a logically isolated virtual network in which customers can organize subnets, routes and connectivity.
D:This statement is true of AWS Transit Gateway, which addresses a company needs a central networking hub connecting multiple VPCs and applicable on-premises networks. It does not explain the particular role of Amazon VPC; A VPC is a logically isolated virtual network in which customers can organize subnets, routes and connectivity.
Question 266
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: plan for sustained essential operations and recovery after disruptive events?
- Elasticity
- Business continuity
- Reduced infrastructure maintenance
- Global reach
Explanation
Correct Answer
B:Business continuity directly addresses this outcome. Business continuity combines preparedness and recovery measures rather than assuming failures will never occur. A common relevant example is: a retailer needs a plan for resuming critical operations after a major disruption.
Incorrect Answers
A:Elasticity instead focuses on a different requirement, such as an online store has unpredictable weekend traffic spikes followed by quiet weekdays. Elasticity aligns live capacity with changing workload demand so idle peak-sized resources do not remain continuously allocated. It is not the primary match for the requirement described here: plan for sustained essential operations and recovery after disruptive events.
C:Reduced infrastructure maintenance instead focuses on a different requirement, such as a small team prefers to focus on application features instead of replacing failed server hardware. AWS handles the facilities and underlying physical infrastructure, freeing customers from those data-center tasks. It is not the primary match for the requirement described here: plan for sustained essential operations and recovery after disruptive events.
D:Global reach instead focuses on a different requirement, such as a software provider wants to serve customers from multiple continents without building overseas data centers. AWS Regions enable deployment in multiple geographies without building and operating a physical data center in each market. It is not the primary match for the requirement described here: plan for sustained essential operations and recovery after disruptive events.
Question 267
A stakeholder is considering AWS Global Accelerator because an internet-facing app has regional endpoints and needs stable global entry points for traffic routing. What is the MOST relevant capability or benefit?
- Place redundant application components across different AZs within a Region
- Deliver cached web content nearer to globally distributed users
- Support global network traffic entry and endpoint routing
- Provide part of a multi-Region continuity plan
Explanation
Correct Answer
C:Use AWS Global Accelerator for global network traffic entry and endpoint routing. Global Accelerator provides static anycast IP addresses and routes traffic over the AWS global network to healthy endpoints. The stated need is specifically an internet-facing app has regional endpoints and needs stable global entry points for traffic routing.
Incorrect Answers
A:This outcome fits Multiple Availability Zones: Multi-AZ deployments can avoid a single-AZ failure taking down the whole application. The stakeholder requires the more specific capability provided by AWS Global Accelerator, not that separate benefit.
B:This outcome fits Amazon CloudFront global caching: CloudFront is AWS's content delivery network and can reduce latency by caching copies near viewers. The stakeholder requires the more specific capability provided by AWS Global Accelerator, not that separate benefit.
D:This outcome fits Multiple AWS Regions: Deploying across Regions can address geographic disruptions, customer latency and residency objectives at higher complexity. The stakeholder requires the more specific capability provided by AWS Global Accelerator, not that separate benefit.
Question 268
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: the customer configures database users and permissions for its application data?
- Shared responsibility varies by service
- Customer Lambda function code
- Customer S3 bucket access
- Customer RDS data permissions
Explanation
Correct Answer
D:Customer RDS data permissions directly addresses this outcome. Selecting a managed database does not transfer responsibility for customer identities and data authorization to AWS. A common relevant example is: an RDS database stores sensitive customer records and must restrict user privileges.
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 configures database users and permissions for its application data.
B: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 configures database users and permissions for its application data.
C: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 configures database users and permissions for its application data.
Question 269
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: meet this requirement: a business analyst occasionally needs to view AWS resources through a browser interface?
- AWS Management Console
- AWS CLI
- AWS Outposts
- AWS CloudFormation
Explanation
Correct Answer
A:AWS Management Console directly addresses this outcome. The AWS Management Console is a browser-based entry point for authorized AWS account users. A common relevant example is: a business analyst occasionally needs to view AWS resources through a browser interface.
Incorrect Answers
B:AWS CLI instead focuses on a different requirement, such as an operations engineer wants to run repeatable AWS service commands from a terminal script. The AWS CLI exposes AWS service operations through command-line commands suitable for controlled automation. It is not the primary match for the requirement described here: meet this requirement: a business analyst occasionally needs to view AWS resources through a browser interface.
C:AWS Outposts instead focuses on a different requirement, such as a manufacturer needs AWS-managed hardware and selected cloud services in its own facility. Outposts extends supported AWS infrastructure and services to customer locations where local processing or data needs apply. It is not the primary match for the requirement described here: meet this requirement: a business analyst occasionally needs to view AWS resources through a browser interface.
D:AWS CloudFormation instead focuses on a different requirement, such as a cloud team must define a repeatable infrastructure configuration under version control. CloudFormation uses templates and stacks to create and manage supported AWS resources consistently. It is not the primary match for the requirement described here: meet this requirement: a business analyst occasionally needs to view AWS resources through a browser interface.
Question 270
Within the Cloud Technology and Services domain, which business example MOST clearly illustrates Amazon Kinesis, rather than a different AWS concept?
- A business wants dashboards and business intelligence over curated organizational data
- An application wants to capture and process a continuous stream of event records
- A company wants a conversational bot that interprets user requests in a customer service channel
- A machine learning team needs tools to build and deploy custom ML models
Explanation
Correct Answer
B:The decisive requirement is: Use Amazon Kinesis for real-time streaming data ingestion and processing use cases. This is the role of Amazon Kinesis. Kinesis includes streaming data capabilities suitable for near-real-time events.
Incorrect Answers
A:This describes a scenario for Amazon Quick: use Amazon Quick for supported business intelligence and analytics experiences. Amazon Quick is the current AWS branding for business intelligence capabilities previously associated with QuickSight. It is not the most direct example of Amazon Kinesis.
C:This describes a scenario for Amazon Lex: use Amazon Lex for building conversational interfaces. Lex provides conversational AI for chatbots and voice-enabled applications. It is not the most direct example of Amazon Kinesis.
D:This describes a scenario for Amazon SageMaker AI: use Amazon SageMaker AI for managed machine learning development workflows. SageMaker AI supports building, training and deploying ML models rather than simply translating text. It is not the most direct example of Amazon Kinesis.
