Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Amazon EFS. (Amazon EFS) is correct because it provides a scalable, POSIX-compliant NFS file system that can be accessed by multiple EC2 instances simultaneously. Option A (Amazon FSx for Windows File Server) uses SMB protocol and is not POSIX-compliant. Option C (Amazon EBS with Multi-Attach) only supports a limited number of instances and has specific constraints, and it is not a fully managed shared file system. Option D (Amazon S3) is object storage and does not provide POSIX compliance.

Answer

Amazon FSx for Windows File Server

Answer

Amazon EBS with Multi-Attach

Answer

Amazon S3

Question 2

A company is migrating a stateful application to AWS and needs to preserve the client IP addresses at the application layer. The application runs on EC2 instances behind a load balancer. Which load balancer type should they use?

Accepted Answer

Network Load Balancer (NLB). (Network Load Balancer) is correct because it preserves the client IP address by default. Option B (ALB) uses proxy protocol, but the application must be configured to parse it. Option C (Classic Load Balancer) does not preserve IP. Option D (Gateway Load Balancer) is for third-party appliances.

Answer

Application Load Balancer (ALB)

Answer

Classic Load Balancer (CLB)

Answer

Gateway Load Balancer (GWLB)

Question 3

A company is migrating a critical application to AWS and must ensure high availability across multiple Availability Zones. Which TWO AWS services can be used to distribute traffic across instances in multiple AZs?

Accepted Answer

Application Load Balancer (ALB). The correct answers are C (Application Load Balancer) and E (Network Load Balancer). Both ALB and NLB are regional load balancers that can distribute traffic across targets in multiple Availability Zones, providing high availability. CloudFront (A) is a global content delivery network, not a regional load balancer. Route 53 (D) is a DNS service that can route traffic but does not perform load balancing across instances. Global Accelerator (B) uses edge locations and typically routes to a regional load balancer, but it is not itself a load balancer that distributes traffic across AZs.

Answer

Amazon CloudFront

Answer

AWS Global Accelerator

Answer

Amazon Route 53

Question 4

A company is migrating a large on-premises data lake to Amazon S3. They need to transfer petabytes of data over the network securely and efficiently. Which TWO AWS services should they use?

Accepted Answer

AWS DataSync. The correct answers are D (AWS DataSync) and E (Amazon S3 Transfer Acceleration). AWS DataSync is an online data transfer service that simplifies, automates, and accelerates moving data between on-premises storage and Amazon S3. Amazon S3 Transfer Acceleration enables fast, secure transfers of data over long distances by using AWS edge locations. Option A (AWS Direct Connect) provides a dedicated network connection but is not a data transfer service itself. Option B (Amazon Kinesis Data Firehose) is for streaming data ingestion, not for large-scale batch transfers. Option C (AWS Snowball Edge) is an offline physical device, not for network-based transfer.

Answer

AWS Direct Connect

Answer

Amazon Kinesis Data Firehose

Answer

AWS Snowball Edge

Question 5

A company is migrating a three-tier web application to AWS and wants to decouple the layers for scalability. Which THREE AWS services should they use?

Accepted Answer

Application Load Balancer (ALB). Options A, B, and C are correct. ALB for web tier, SQS for decoupling, and RDS for database. Option D (CloudFront) is a CDN, not for decoupling. Option E (ElastiCache) is optional caching.

Answer

Amazon CloudFront

Answer

Amazon ElastiCache

Question 6

A company is migrating an on-premises Oracle database to Amazon Aurora PostgreSQL. They need to minimize downtime and ensure data integrity. Which AWS service should they use for the migration?

Accepted Answer

AWS Database Migration Service (DMS). AWS Database Migration Service (DMS) supports homogeneous and heterogeneous migrations with minimal downtime. Option A is wrong because SCT only helps with schema conversion, not the actual data migration. Option C is wrong because DataSync is for file storage, not databases. Option D is wrong because Snowball Edge is for large-scale offline data transfer, not online database migration.

Answer

AWS Schema Conversion Tool (SCT)

Answer

AWS DataSync

Answer

AWS Snowball Edge

Question 7

A company is using the 7 Rs strategy to migrate a monolithic application to AWS. They want to move the application to the cloud without modifying the code but plan to later refactor parts of it. Which migration strategy should they choose initially?

Accepted Answer

Rehost. Rehost (lift-and-shift) is the correct initial strategy because it moves the application to AWS without modifying any code, aligning with the company's goal to first migrate without changes and later refactor. Relocate (A) involves moving the hypervisor, not the application itself. Refactor (B) involves rewriting or re-architecting the application, which is not desired initially. Replatform (C) involves making some cloud optimizations that could require minor code changes.

Answer

Relocate

Answer

Refactor

Answer

Replatform

Question 8

A company is migrating a legacy .NET Framework 4.7 application to AWS. The application uses Windows authentication and COM+ components. Which migration approach is most suitable?

Accepted Answer

Use Windows containers on Amazon ECS with Amazon ECS-optimized Windows Server AMI. Windows containers on Amazon ECS with the ECS-optimized Windows Server AMI support .NET Framework applications and COM+ components, making them the most suitable migration approach. Option A is incorrect because replatforming to .NET Core on Linux would require significant code changes and does not support COM+. Option C is incorrect because AWS Lambda does not support full .NET Framework or COM+. Option D is incorrect because Linux containers cannot run Windows-based .NET Framework applications.

Answer

Replatform to .NET Core on AWS Elastic Beanstalk (Linux)

Answer

Refactor to run on AWS Lambda with .NET Core 3.1

Answer

Containerize with Linux containers on Amazon ECS

Question 9

A company is migrating an on-premises application to AWS. The application requires low-latency access to a file system that can be mounted by multiple EC2 instances simultaneously. Which AWS storage service should they use?

Accepted Answer

Amazon EFS. Amazon EFS is a scalable, elastic file system for Linux-based workloads that can be mounted by multiple EC2 instances simultaneously, providing low-latency access. S3 is object storage, not a file system, so it does not support file-level mounts. Amazon EBS volumes (including multi-attach) are block storage typically attached to a single instance; while io1/io2 with multi-attach can be shared, it is limited and not designed as a general-purpose shared file system. Amazon FSx for Windows File Server is a managed Windows file server, suitable for Windows workloads, but EFS is simpler and more cost-effective for Linux-based applications requiring shared file access.

Answer

Amazon S3

Answer

Amazon FSx for Windows File Server

Answer

Amazon EBS

Question 10

A company is migrating a stateful web application to AWS. The application uses local storage for user sessions. Which AWS service can help make the application stateless and scalable?

Accepted Answer

Amazon ElastiCache. Amazon ElastiCache provides a managed in-memory cache that can store session data externally, allowing the web application to be stateless and scale horizontally. Amazon EBS volumes are attached to a single EC2 instance and cannot be shared across instances, so they do not help with statelessness. Amazon RDS is for relational databases and is not optimized for low-latency session state. Amazon S3 is an object store with higher latency and is not suitable for frequent session reads/writes.

Answer

Amazon EBS

Answer

Amazon RDS

Answer

Amazon S3

Question 11

A company is migrating a large-scale Hadoop cluster to Amazon EMR. They want to optimize costs by using transient clusters and storing data in Amazon S3. Which feature should they enable on the EMR cluster to improve performance?

Accepted Answer

EMRFS consistent view. Amazon EMRFS with consistent view improves performance when using transient clusters and storing data in Amazon S3 by providing consistent metadata and read-after-write consistency. Option A (Auto Scaling) adjusts cluster size for compute needs, not storage performance. Option B (Kerberos authentication) is a security feature. Option D (EBS-optimized instances) ensures dedicated network bandwidth for EBS volumes, which does not directly enhance S3 I/O performance.

Answer

Auto Scaling

Answer

Kerberos authentication

Answer

EBS-optimized instances

Question 12

A company is planning to migrate a Microsoft SQL Server database to Amazon RDS for SQL Server. They want to automate the migration process and minimize manual effort. Which AWS service should they use?

Accepted Answer

AWS Database Migration Service (DMS). AWS DMS can migrate SQL Server to RDS with minimal downtime. Option A is wrong because CloudEndure Migration is for server migration. Option B is wrong because DataSync is for file data. Option D is wrong because Schema Conversion Tool is for schema conversion.

Answer

AWS CloudEndure Migration

Answer

AWS DataSync

Answer

AWS Schema Conversion Tool (SCT)

Question 13

A company is migrating a containerized application to Amazon ECS. The application requires persistent storage that can be shared across multiple containers running on different EC2 instances. Which storage solution should they use?

Accepted Answer

Amazon EFS. Amazon EFS provides a shared file system that can be accessed by multiple EC2 instances concurrently, making it ideal for persistent storage shared across containers in Amazon ECS. Option A (Amazon FSx for Lustre) is designed for high-performance computing workloads and is not intended for general shared container storage. Option B (Amazon EBS) volumes are block-level storage that can only be attached to a single EC2 instance at a time, so they cannot be shared across multiple instances. Option D (Amazon S3) is object storage, not a file system, and does not provide a standard file system interface that containers require.

Answer

Amazon FSx for Lustre

Answer

Amazon EBS

Answer

Amazon S3

Question 14

A company is migrating a legacy on-premises application that uses a custom TCP protocol. The application needs to be accessible from the internet while maintaining security. Which AWS service should they use to expose the application without modifying the code?

Accepted Answer

Network Load Balancer (NLB). Network Load Balancer (NLB) because it operates at Layer 4 (TCP) and can handle custom TCP protocols without requiring application modifications. Option A (CloudFront) is a content delivery network that only supports HTTP/HTTPS. Option C (API Gateway) is designed for HTTP/HTTPS APIs and does not handle raw TCP traffic. Option D (Application Load Balancer, ALB) operates at Layer 7 (HTTP/HTTPS) and cannot process custom TCP protocols.

Answer

Amazon CloudFront

Answer

Amazon API Gateway

Answer

Application Load Balancer (ALB)

Question 15

A company is migrating a large number of files from on-premises to Amazon S3. The files are accessed frequently and require low latency. Which TWO AWS services can help accelerate the migration? (Choose TWO.)

Accepted Answer

AWS DataSync. Correct answers: C (AWS DataSync) and E (AWS Snowball Edge). AWS DataSync automates and accelerates transferring large amounts of data over the network, making it ideal for frequent, low-latency access. AWS Snowball Edge is a petabyte-scale data transport solution that uses secure physical devices to transfer large datasets offline, bypassing network constraints. Option A (AWS Storage Gateway) is a hybrid storage service, not a migration accelerator. Option B (AWS CloudFormation) is for infrastructure as code, not data transfer. Option D (Amazon S3 Transfer Acceleration) speeds up uploads but is a feature of S3, not a standalone migration service.

Answer

AWS Storage Gateway

Answer

AWS CloudFormation

Answer

Amazon S3 Transfer Acceleration
