Question 221

A company wants to host a static website using Amazon S3. Which configuration is required to make the website content available to users?

1. Create an S3 bucket and configure static website hosting
2. Attach an EBS volume to the S3 bucket
3. Configure an EC2 Auto Scaling group
4. Create an RDS Multi-AZ deployment

Correct Answer: 1

Explanation

Amazon S3 can host static website content such as HTML, CSS, JavaScript, images, and other static files. The organization can configure static website hosting on an S3 bucket and place the website objects in the bucket. Appropriate permissions or an access architecture must also be configured so users can retrieve the required content. EBS is block storage, Auto Scaling manages EC2 capacity, and RDS provides managed relational databases. S3 static website hosting is therefore appropriate for websites that do not require server-side processing.

Question 222

Which AWS service provides a managed API front door that can receive HTTP requests and invoke backend services such as Lambda?

1. Amazon CloudFront
2. Amazon API Gateway
3. Amazon Route 53
4. Amazon SQS

Correct Answer: 2

Explanation

Amazon API Gateway provides managed APIs that can receive HTTP or HTTPS requests and route them to backend services such as Lambda functions, HTTP endpoints, or other AWS integrations. It can provide features such as authentication, throttling, monitoring, and request management. This makes it useful for building serverless APIs without managing API servers. CloudFront focuses on content delivery, Route 53 provides DNS services, and SQS provides asynchronous messaging. API Gateway is therefore the appropriate service for creating a managed API front door.

Question 223

A company wants to encrypt data stored in Amazon S3 using server-side encryption with an AWS Key Management Service key. Which option should be selected?

1. SSE-S3
2. SSE-KMS
3. Client-side encryption only
4. S3 Transfer Acceleration

Correct Answer: 2

Explanation

S3 Server-Side Encryption with AWS KMS keys, commonly called SSE-KMS, encrypts objects at rest using keys managed through AWS Key Management Service. It provides additional control over key policies, permissions, and auditing compared with S3-managed encryption keys. SSE-S3 also provides server-side encryption but uses S3-managed keys. Client-side encryption requires the application to encrypt data before sending it to S3, while Transfer Acceleration is designed to improve transfer performance. SSE-KMS is therefore appropriate when S3 data must use KMS-managed encryption keys.

Question 224

A company has a workload that requires extremely high network throughput and low latency between EC2 instances. Which placement group should be considered?

1. Spread placement group
2. Partition placement group
3. Cluster placement group
4. Regional placement group

Correct Answer: 3

Explanation

A cluster placement group places EC2 instances close together within an Availability Zone. This arrangement is designed to provide low-latency networking and high network throughput between instances. It is useful for tightly coupled workloads such as high-performance computing applications that require frequent communication between instances. Spread placement groups focus on isolating instances across hardware, while partition placement groups provide logical hardware partitions for distributed applications. Cluster placement groups are therefore appropriate when minimizing network latency and maximizing communication performance between EC2 instances are important.

Question 225

Which AWS database service is designed to provide a serverless, distributed relational database compatible with MySQL and PostgreSQL?

1. Amazon Aurora
2. Amazon DynamoDB
3. Amazon Redshift
4. Amazon ElastiCache

Correct Answer: 1

Explanation

Amazon Aurora is a managed relational database engine compatible with MySQL and PostgreSQL. Aurora is designed for high availability, durability, and scalability and separates database compute from its distributed storage architecture. Aurora Serverless can automatically adjust database capacity based on application demand for supported workloads. DynamoDB is a NoSQL database, Redshift is a data warehouse, and ElastiCache provides in-memory caching. Aurora is therefore the appropriate choice when an application requires a managed relational database compatible with MySQL or PostgreSQL and scalable AWS infrastructure.

Question 226

A company wants to allow users to download a private S3 object for a limited period without making the object publicly accessible. Which solution should be used?

1. S3 public bucket policy
2. CloudFront without access controls
3. S3 presigned URL
4. Internet Gateway

Correct Answer: 3

Explanation

An S3 presigned URL provides temporary access to a specific private S3 object without changing the object’s public access permissions. The URL is generated with a defined expiration period and can be provided to an authorized user or application. This approach is useful for temporary downloads and uploads while keeping the underlying bucket or object private. A public bucket policy would expose data more broadly, CloudFront without appropriate access controls does not solve the requirement by itself, and an Internet Gateway provides network connectivity rather than object authorization.

Question 227

Which AWS service is best suited for storing and retrieving application data using a key-value model with consistently low latency at large scale?

1. Amazon RDS
2. Amazon DynamoDB
3. Amazon Redshift
4. Amazon FSx

Correct Answer: 2

Explanation

Amazon DynamoDB is a fully managed NoSQL database that supports key-value and document data models. It is designed to provide low-latency performance at large scale without requiring customers to manage database servers. DynamoDB is particularly suitable for applications such as gaming, mobile applications, shopping carts, and high-volume transactional workloads. RDS provides relational databases, Redshift is optimized for analytics, and FSx provides managed file systems. DynamoDB is therefore the appropriate choice for highly scalable key-value workloads requiring consistently low latency.

Question 228

A company wants to prevent unauthorized users from making AWS API changes even if they have permissions in an individual account. Which organization-level control can establish such restrictions?

1. Security group
2. Network ACL
3. Service Control Policy
4. Route table

Correct Answer: 3

Explanation

A Service Control Policy (SCP) in AWS Organizations defines the maximum available permissions for accounts or organizational units. SCPs can restrict which AWS services and actions accounts are allowed to use, even when IAM policies within those accounts grant broader permissions. SCPs do not directly grant permissions; instead, they establish organization-level permission boundaries. Security groups and NACLs control network traffic, while route tables determine traffic destinations. An SCP is therefore appropriate when centralized organizational restrictions must apply across AWS accounts.

Question 229

Which AWS service can distribute messages from one publisher to multiple subscribers using a publish/subscribe model?

1. Amazon SNS
2. Amazon EBS
3. Amazon RDS
4. AWS Config

Correct Answer: 1

Explanation

Amazon Simple Notification Service (SNS) provides a publish/subscribe messaging model in which publishers send messages to topics and multiple subscribers can receive those messages. SNS is useful for application notifications, fanout architectures, and event distribution. A single message can be delivered to multiple subscribed endpoints, helping decouple application components. EBS provides block storage, RDS provides relational databases, and Config manages resource configuration compliance. SNS is therefore the appropriate AWS service when one publisher needs to distribute notifications or messages to multiple subscribers.

Question 230

Which AWS service can provide centralized audit logs of AWS API activity across multiple AWS accounts when configured as an organization trail?

1. AWS Config
2. Amazon CloudWatch
3. AWS CloudTrail
4. Amazon GuardDuty

Correct Answer: 3

Explanation

AWS CloudTrail records AWS API activity and can be configured as an organization trail to collect activity across multiple AWS accounts. Centralized CloudTrail logging helps organizations investigate security events, monitor administrative actions, and maintain an audit history. Logs can be delivered to destinations such as Amazon S3 for long-term retention and analysis. Config focuses on resource configurations, CloudWatch focuses on monitoring and logs, and GuardDuty analyzes activity for potential threats. CloudTrail is therefore the appropriate service for centralized API auditing across accounts.

Question 231

An application requires a queue that can retain messages when consumers are temporarily unavailable and can move repeatedly failed messages to a separate queue. Which combination should be used?

1. SNS topic and CloudFront
2. SQS queue and dead-letter queue
3. EventBridge and Route 53
4. S3 bucket and EFS

Correct Answer: 2

Explanation

Amazon SQS can buffer messages while consumers are unavailable or processing workloads slowly. A dead-letter queue (DLQ) can be configured to receive messages that cannot be successfully processed after a specified number of delivery attempts. This helps isolate problematic messages for investigation without continually blocking normal processing. SNS is primarily a publish/subscribe service, EventBridge routes events, S3 provides object storage, and EFS provides shared file storage. SQS combined with a DLQ is therefore appropriate for resilient asynchronous processing with failure isolation.

Question 232

Which AWS service provides a managed DNS service that can route users to application endpoints based on geographic location?

1. Amazon Route 53
2. AWS Global Accelerator
3. Amazon CloudFront
4. AWS Transit Gateway

Correct Answer: 1

Explanation

Amazon Route 53 is a managed DNS service that supports several routing policies, including geolocation routing. Geolocation routing can direct users to different resources based on the geographic location from which DNS queries originate. This can be useful for applications that need region-specific content, compliance-based routing, or geographically tailored experiences. Global Accelerator provides static global IP addresses and network-level routing, CloudFront provides content delivery, and Transit Gateway connects networks. Route 53 is therefore the appropriate service for DNS-based geographic routing.

Question 233

A company wants to protect an application from accidental deletion of important S3 objects while still allowing administrators to recover previous versions. Which feature should be enabled?

1. S3 Versioning
2. S3 Transfer Acceleration
3. S3 Intelligent-Tiering
4. S3 Access Points

Correct Answer: 1

Explanation

S3 Versioning maintains multiple versions of objects within a bucket. When an object is overwritten or deleted, previous versions can remain available, allowing administrators to recover data from accidental changes or deletions. Versioning is particularly useful for data protection and recovery scenarios. Transfer Acceleration improves transfer performance, Intelligent-Tiering automatically moves objects between access tiers, and Access Points provide alternative access management endpoints. S3 Versioning is therefore the appropriate feature when the primary requirement is recovering previous object versions after accidental modification or deletion.

Question 234

Which AWS service provides a managed relational database failover capability by maintaining a standby database in another Availability Zone?

1. Amazon DynamoDB
2. Amazon RDS Multi-AZ
3. Amazon S3
4. Amazon Athena

Correct Answer: 2

Explanation

Amazon RDS Multi-AZ deployments improve database availability by maintaining a standby database instance in another Availability Zone. The standby is designed for failover rather than serving normal read traffic, and RDS manages the failover process when the primary database becomes unavailable. This architecture protects against certain infrastructure and Availability Zone failures. DynamoDB is a NoSQL database, S3 provides object storage, and Athena queries data in S3. RDS Multi-AZ is therefore appropriate when a managed relational database requires high availability and automated failover.

Question 235

Which AWS service allows a company to centrally store configuration parameters that applications can retrieve without embedding them in source code?

1. AWS Systems Manager Parameter Store
2. Amazon CloudFront
3. AWS Shield
4. Amazon Redshift

Correct Answer: 1

Explanation

AWS Systems Manager Parameter Store provides centralized storage for configuration values and parameters that applications can retrieve at runtime. Parameters can be used for values such as environment settings, configuration strings, and other operational information. SecureString parameters can also be protected using AWS KMS encryption. Keeping configuration outside application source code makes deployments easier to manage and reduces the need to hard-code sensitive or environment-specific values. CloudFront provides content delivery, Shield provides DDoS protection, and Redshift provides analytics. Parameter Store is therefore the appropriate choice.

Question 236

A company needs to connect multiple VPCs privately, but the number of VPCs is small and the organization wants direct connectivity between specific VPC pairs. Which solution is appropriate?

1. NAT Gateway
2. VPC Peering
3. Internet Gateway
4. AWS WAF

Correct Answer: 2

Explanation

VPC Peering provides private network connectivity between two VPCs using AWS networking infrastructure. It is useful when a small number of VPCs need direct communication and the organization does not require a centralized network hub. Peering connections can be established between VPCs subject to supported networking requirements and routing configuration. NAT Gateway provides outbound internet access for private resources, Internet Gateway provides internet connectivity, and WAF protects web applications. VPC Peering is therefore suitable for direct private connectivity between a small number of VPCs.

Question 237

Which AWS service can automatically move data between S3 storage classes based on predefined time or access rules?

1. Amazon EFS
2. S3 Lifecycle
3. AWS Backup
4. Amazon CloudWatch

Correct Answer: 2

Explanation

Amazon S3 Lifecycle allows organizations to define rules that automatically transition objects between supported S3 storage classes or expire objects after specified periods. For example, frequently accessed objects can remain in S3 Standard and later transition to an infrequent-access or archival class when they become less valuable to keep in higher-cost storage. This automation can reduce storage costs and simplify data management. EFS provides file storage, AWS Backup manages backups, and CloudWatch provides monitoring. S3 Lifecycle is therefore the correct choice for automated object transitions.

Question 238

Which AWS service provides a managed relational database engine designed for analytical workloads using columnar storage and massively parallel processing?

1. Amazon Redshift
2. Amazon DynamoDB
3. Amazon RDS
4. Amazon EFS

Correct Answer: 1

Explanation

Amazon Redshift is a managed data warehouse designed for large-scale analytical workloads. It uses columnar storage and massively parallel processing to efficiently execute complex analytical queries across large datasets. Redshift is commonly used for business intelligence, reporting, data analysis, and data warehouse workloads. DynamoDB is a NoSQL transactional database, RDS provides general-purpose relational databases, and EFS provides shared file storage. Redshift is therefore the appropriate AWS service when organizations need a managed analytical data warehouse optimized for large-scale queries.

Question 239

Which AWS service can provide a private endpoint in a VPC for accessing supported AWS services without requiring public IP addresses?

1. AWS PrivateLink
2. Amazon Route 53
3. Amazon S3 Transfer Acceleration
4. AWS Direct Connect

Correct Answer: 1

Explanation

AWS PrivateLink enables private connectivity to supported services through interface VPC endpoints. Traffic remains on the AWS network instead of requiring access through public internet connectivity. PrivateLink is useful when applications need private access to AWS services or supported endpoint services while avoiding public IP addresses. Route 53 provides DNS, S3 Transfer Acceleration improves object transfer performance, and Direct Connect provides dedicated connectivity from external networks to AWS. PrivateLink is therefore the appropriate technology for private endpoint-based service access within a VPC.

Question 240

A company has an application with unpredictable traffic and wants to automatically increase or decrease EC2 capacity according to demand. Which combination is most appropriate?

1. AWS CloudTrail and AWS Config
2. Amazon S3 and Amazon CloudFront
3. EC2 Auto Scaling and CloudWatch metrics
4. Amazon RDS and Amazon ElastiCache

Correct Answer: 3

Explanation

EC2 Auto Scaling can automatically increase or decrease the number of EC2 instances based on configured scaling policies. CloudWatch metrics provide the monitoring data that can be used to trigger scaling actions, such as average CPU utilization or application-specific metrics. This combination allows applications to adapt capacity to changing demand while maintaining configured minimum and maximum limits. CloudTrail and Config are auditing and configuration services, while S3 and CloudFront address storage and content delivery. EC2 Auto Scaling with CloudWatch metrics is therefore the appropriate solution for dynamic compute scaling.
