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

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 2

A company is migrating a monolithic application to AWS and wants to adopt a microservices architecture. The application currently runs on a single server and uses a shared MySQL database. Which AWS service can help the company decouple the microservices and enable asynchronous communication?

Accepted Answer

Amazon Simple Queue Service (SQS). Amazon SQS is a fully managed message queuing service that enables asynchronous communication and decoupling between microservices. By using SQS, the monolithic application can be broken into independent services that communicate via queues, improving scalability and resilience. SQS is specifically designed for decoupling and asynchronous messaging, making it the correct choice.

Amazon API Gateway

Answer

AWS Step Functions

Answer

Elastic Load Balancing

Question 3

A company is migrating a critical application to AWS and needs to ensure that the migration has minimal downtime. The application uses a SQL Server database. The company wants to use AWS Database Migration Service (DMS) for the migration. What should the company do to minimize downtime during the database migration?

Accepted Answer

Use DMS with ongoing replication (change data capture) to keep the target database synchronized, then perform a brief cutover.. Using change data capture (CDC) with AWS DMS enables ongoing replication of changes from the source SQL Server database to the target. This keeps the target nearly synchronized, so during cutover only a brief pause is needed to apply any final changes, minimizing downtime. Option A is incorrect because enabling validation does not reduce downtime; it only verifies data integrity after migration, and truncating the target before cutover would remove all data, causing potential data loss and additional downtime. Option C is incorrect because a full load only captures a snapshot of the database at a point in time; any changes after that require a separate sync, leading to longer downtime. Option D is incorrect because manually copying remaining data after a full load migration defeats the purpose of using DMS and introduces significant downtime and risk of inconsistency.

Answer

Use DMS with validation enabled and then truncate the target before cutover.

Answer

Use DMS with full load only and schedule the migration during a maintenance window.

Answer

Perform a full load migration using DMS and then manually copy any remaining data.

Question 4

A company is migrating its on-premises data center to AWS. The company has over 200 applications, each with varying dependencies. The migration team wants to use AWS Migration Hub to track the migration progress. Which approach should the team take to ensure successful tracking and minimize manual effort?

Accepted Answer

Use AWS Application Discovery Service to discover dependencies and then use AWS Migration Hub to track the migration of each application.. AWS Application Discovery Service automatically discovers on-premises servers and their dependencies, and its data feeds directly into AWS Migration Hub, which tracks migration status across applications. This combination minimizes manual effort and gives accurate dependency mapping for 200+ applications.

Answer

Use Amazon CloudWatch dashboards to monitor the health of on-premises servers.

Answer

Use AWS Systems Manager to automate the migration of each application.

Answer

Manually create a spreadsheet of all applications and their dependencies, and update it weekly.

Question 5

A company wants to migrate its on-premises file server to AWS. The file server contains 10 TB of data that changes infrequently. The company has a limited bandwidth internet connection and needs to complete the migration within one week. Which AWS service should the company use for the initial data transfer?

Accepted Answer

AWS Snowball Edge. AWS Snowball Edge. This is the best option for migrating 10 TB of data over a limited bandwidth connection within a week, as it physically transfers the data via a portable storage device, bypassing the need for network bandwidth. Option A (Amazon S3 Transfer Acceleration) is incorrect because it still relies on internet bandwidth, which is insufficient for the given timeline. Option C (AWS DMS) is for database migrations, not file servers. Option D (AWS DataSync) also requires network connectivity and bandwidth, making it unsuitable for the large initial transfer over a slow connection.

Answer

Amazon S3 Transfer Acceleration

Answer

AWS Database Migration Service (DMS)

Answer

AWS DataSync

Question 6

A company is planning to migrate its on-premises Oracle database to Amazon RDS for Oracle. The database is 2 TB in size and the company has a high-speed network connection to AWS. Which AWS service should the company use to migrate the database with minimal downtime?

Accepted Answer

AWS Database Migration Service (DMS). AWS DMS supports Oracle to RDS for Oracle migration with ongoing replication for minimal downtime. Option A is incorrect because S3 Transfer Acceleration is used for accelerating uploads to S3, not for database migration. Option C is incorrect because Snowball Edge is for offline data transfer and not suitable for databases with minimal downtime. Option D is incorrect because AWS Schema Conversion Tool (SCT) is used for schema conversion, not data migration.

Answer

Amazon S3 Transfer Acceleration

Answer

AWS Snowball Edge

Answer

AWS Schema Conversion Tool (SCT)

Question 7

A company is migrating its on-premises applications to AWS. The company has a mix of Windows and Linux servers. The migration team wants to automate the discovery of application dependencies and track the migration progress. Which TWO AWS services should the team use? (Choose TWO.)

Accepted Answer

AWS Application Discovery Service. AWS Application Discovery Service (option C) is correct because it is purpose-built to automatically discover on-premises servers (both Windows and Linux via the Discovery Agent or agentless VMware collector) and map application dependencies, network connections, and performance data to support migration planning. AWS Migration Hub (option E) is correct because it provides a single location to track the progress of application migrations across multiple AWS and partner migration tools, giving the team the migration-tracking capability they require. Together these two services directly address the stated goals of dependency discovery and progress tracking. AWS Systems Manager (option A) is for operational management of EC2 and hybrid instances (patching, run commands, inventory), not for discovering on-premises application dependencies or tracking migrations. AWS Config (option B) evaluates and records resource configuration compliance, and AWS CloudTrail (option D) logs API activity for auditing — neither performs dependency discovery or migration progress tracking.

Answer

AWS Systems Manager

Answer

AWS Config

Answer

AWS CloudTrail

Question 8

A company is planning to migrate a three-tier web application to AWS. The application consists of a web server, an application server, and a MySQL database. The company wants to minimize operational overhead and improve scalability. Which THREE AWS services should the company use to modernize the architecture? (Choose THREE.)

Accepted Answer

Elastic Load Balancing (ELB). Elastic Load Balancing (ELB) [CORRECT] is right because it distributes incoming traffic across multiple targets in the web tier, enabling horizontal scaling and high availability without managing load-balancing servers. Amazon ECS with Fargate [CORRECT] is right because it runs the application tier as containers with serverless compute, eliminating EC2 instance provisioning and patching, which directly reduces operational overhead while supporting automatic scaling. Amazon RDS for MySQL [CORRECT] is right because it provides a managed MySQL-compatible database with automated backups, patching, Multi-AZ failover, and read replicas, replacing self-managed MySQL and improving scalability. AWS Lambda is not selected because the scenario calls for a three-tier architecture with a dedicated application server tier, which ECS with Fargate addresses more directly. Amazon EC2 instances are not selected because managing them increases operational overhead, contrary to the goal of minimizing it.

Answer

AWS Lambda

Answer

Amazon EC2 instances

Question 9

A company is migrating a legacy monolithic application to AWS. The application has tightly coupled components and high latency between them. The company wants to modernize the application into a microservices architecture. Which migration strategy should the company use?

Accepted Answer

Refactor / Re-architect. The refactor/re-architect strategy involves re-architecting the application into microservices. Option A is wrong because repurchase involves buying a new product, not re-architecting. Option B is wrong because rehost (lift-and-shift) does not modernize. Option D is wrong because replatform (lift-tinker-and-shift) makes minor optimizations but does not change architecture.

Answer

Repurchase

Answer

Rehost

Answer

Replatform

Question 10

A company is migrating a large Oracle database to Amazon Aurora PostgreSQL. The migration must have minimal downtime and support ongoing replication. Which AWS service should the company use?

Accepted Answer

AWS Database Migration Service. AWS Database Migration Service (DMS), is the correct answer because it is specifically designed for migrating databases to AWS with minimal downtime, and it supports ongoing replication from Oracle to Aurora PostgreSQL using change data capture (CDC). Option A is incorrect because AWS Application Discovery Service is used for discovering on-premises servers and applications, not for database migration. Option B is incorrect because AWS Server Migration Service (now part of SMS) is for migrating virtual machines, not databases. Option D is incorrect because AWS Schema Conversion Tool (SCT) is used to convert the database schema from one engine to another, not for ongoing replication; it is often used alongside DMS.

Answer

AWS Application Discovery Service

Answer

AWS Server Migration Service

Answer

AWS Schema Conversion Tool

Question 11

A company is migrating a legacy application that uses TCP on port 8080 to AWS. The application must be accessible from the internet. The company wants to use an Application Load Balancer. What must the company do to ensure the load balancer can accept traffic on port 8080?

Accepted Answer

Create a listener for port 8080 on the ALB.. An ALB requires a listener for each port it accepts traffic on; to accept TCP on port 8080, you must create a listener on port 8080 with rules forwarding to the target group. The security group must also allow 8080, but the listener is the ALB configuration step that enables the port.

Answer

Configure the security group to allow inbound traffic on port 80 and 443 only.

Answer

Change the ALB's default port to 8080.

Answer

Assign an Elastic IP address to the ALB.

Question 12

A company is migrating a critical application to AWS and needs to ensure it meets a Recovery Time Objective (RTO) of 15 minutes and a Recovery Point Objective (RPO) of 5 minutes. The application runs on EC2 with an EBS volume. Which configuration should the company use?

Accepted Answer

EC2 instance with Elastic Disaster Recovery service.. AWS Elastic Disaster Recovery (DRS) continuously replicates source servers (including EC2 and on-premises) to a staging area in AWS with sub-second RPO, and can launch recovery instances in minutes, meeting both the 5-minute RPO and 15-minute RTO. It supports point-in-time recovery and automated drills, making it the purpose-built DR service for these targets.

Answer

Multi-AZ deployment with synchronous replication between two instances.

Answer

Single EC2 instance with EBS snapshots every 5 minutes.

Answer

Two EC2 instances in an Auto Scaling group with a warm standby.

Question 13

A company is migrating a batch processing workload to AWS. The workload runs a Java application that processes files from an S3 bucket. The company wants to minimize operational overhead. Which AWS service should the company use to run the Java application?

Accepted Answer

AWS Lambda. (AWS Lambda) is correct because it allows running Java code in response to S3 events with no server management, minimizing operational overhead. AWS Lambda supports Java runtime, can be triggered by S3 object creation events, and automatically scales. Options A (Amazon EC2) and B (Amazon ECS with EC2 launch type) require managing EC2 instances or cluster, increasing overhead. Option C (AWS Batch) is designed for batch jobs but still requires compute environments (EC2 or Fargate) and is more complex than Lambda for simple file processing.

Answer

Amazon EC2

Answer

Amazon ECS with EC2 launch type

Answer

AWS Batch

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?

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

Accepted Answer

Deploy the application on Amazon EC2 instances joined to an AWS Managed Microsoft AD directory.. AWS Managed Microsoft AD is a fully managed Active Directory service in AWS that supports domain join for EC2 instances. By joining the EC2 instances to the directory, the legacy .NET application can continue using Windows Authentication (Kerberos/NTLM) without code changes. This preserves the existing authentication mechanism and minimizes migration effort.

Answer

Use AWS Systems Manager to store credentials and inject them at runtime.

Answer

Migrate the application to Amazon WorkDocs and configure single sign-on.

Answer

Use Amazon Cognito user pools for authentication.

Question 15

A company wants to modernize a legacy monolithic application by decomposing it into microservices. The application handles HTTP requests and uses a MySQL database. The company needs to decouple the microservices and improve scalability. Which AWS services should be used?

Accepted Answer

Amazon SQS for decoupling and Amazon Aurora MySQL for data.. Amazon SQS is a fully managed message queuing service that decouples microservices, allowing asynchronous communication and improved scalability. Amazon Aurora MySQL is a MySQL-compatible relational database that provides high performance and scalability, making it suitable for the existing MySQL workload. Together, they meet the requirements of decoupling and data management without re-architecting the database engine.

Answer

Amazon S3 for decoupling and Amazon RDS for MySQL.

Answer

Amazon SQS for decoupling and Amazon DynamoDB for data.

Answer

Amazon Kinesis Data Streams for decoupling and Amazon RDS for MySQL.
