Question 2

A company is moving a legacy application that uses a shared file system to AWS. The application requires POSIX-compliant file storage that can be accessed by multiple EC2 instances simultaneously. Which AWS storage service should they use?

Accepted Answer

Amazon EFS. Option C (Amazon EFS) is correct because it provides a scalable, POSIX-compliant NFS file system for EC2. Option A (S3) is object storage, not POSIX. Option B (EBS) can only be attached to one instance at a time. Option D (FSx for Windows) is for SMB, not POSIX.

Question 3

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). Option A (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)

Question 4

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). Options A and B are correct. ALB and NLB both distribute traffic across AZs. Option C (CloudFront) is a CDN, not regional load balancing. Option D (Route 53) is DNS, not a load balancer. Option E (Global Accelerator) uses edge locations and then routes to a load balancer.

Answer

Amazon CloudFront

Answer

AWS Global Accelerator

Answer

Amazon Route 53

Question 5

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?

Option C (Direct Connect) is a network service, not a transfer service. Option E (Kinesis Firehose) is for streaming data.

Answer

AWS Direct Connect

Answer

Amazon Kinesis Data Firehose

Answer

AWS Snowball Edge

Question 6

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 (ElastiCache) is optional caching. Option E (CloudFront) is a CDN, not for decoupling.

Answer

Amazon CloudFront

Answer

Amazon ElastiCache

Question 7

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 B is wrong because DataSync is for file storage. Option D is wrong because Snowball is for large-scale data transfer, not database migration.

Answer

AWS Schema Conversion Tool (SCT)

Answer

AWS DataSync

Answer

AWS Snowball Edge

Question 8

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) moves the application as-is without code changes. Option A is wrong because Replatform involves minor optimizations. Option C is wrong because Refactor involves code changes. Option D is wrong because Relocate moves only the server level.

Answer

Relocate

Answer

Refactor

Answer

Replatform

Question 9

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 Windows Server Core support .NET Framework applications and COM+. Option A is wrong because Linux containers do not support .NET Framework. Option B is wrong because Elastic Beanstalk with Linux does not support .NET Framework. Option D is wrong because Lambda does not support full .NET Framework.

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 10

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 provides a scalable, shared file system for multiple EC2 instances. Option A is wrong because S3 is object storage, not a file system. Option B is wrong because EBS volumes can only be attached to a single instance (except multi-attach io1/io2). Option D is wrong because FSx for Windows File Server is for Windows workloads, but EFS is simpler for Linux.

Answer

Amazon S3

Answer

Amazon FSx for Windows File Server

Answer

Amazon EBS

Question 11

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 an in-memory cache for session data, making the application stateless. Option A is wrong because S3 is slower for session data. Option B is wrong because EBS does not provide shared storage across instances. Option D is wrong because RDS is for relational data, not session state.

Answer

Amazon EBS

Answer

Amazon RDS

Answer

Amazon S3

Question 12

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 and S3DistCp improves performance by using S3 as storage. Option A is wrong because EBS-optimized is for network performance. Option B is wrong because Kerberos is for security. Option D is wrong because Auto Scaling is for compute, not storage performance.

Answer

Auto Scaling

Answer

Kerberos authentication

Answer

EBS-optimized instances

Question 13

AWS CloudEndure Migration

Answer

AWS DataSync

Answer

AWS Schema Conversion Tool (SCT)

Question 14

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 accessible from multiple instances. Option A is wrong because EBS volumes are single-instance. Option B is wrong because S3 is not a file system. Option D is wrong because FSx for Lustre is for high-performance computing.

Answer

Amazon FSx for Lustre

Answer

Amazon EBS

Answer

Amazon S3

Question 15

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). AWS Network Load Balancer (NLB) supports TCP protocols and can be used without modifying the application. Option A is wrong because ALB is for HTTP/HTTPS.
