Question 1

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.)

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

Accepted Answer

Elastic Load Balancing (ELB). (Elastic Load Balancing) distributes incoming traffic across multiple targets, improving scalability and availability. Option D (Amazon ECS with Fargate) runs containers without managing servers, reducing operational overhead. Option E (Amazon RDS for MySQL) manages the MySQL database with automated backups, patching, and scaling, minimizing administrative tasks. Option A (AWS Lambda) is not suitable for long-running application servers due to execution time limits and stateless nature. Option C (Amazon EC2 instances) requires manual management of instances, increasing operational overhead.

Answer

AWS Lambda

Answer

Amazon EC2 instances

Question 2

A company is migrating 50 on-premises web applications to AWS. Each application has a different OS and middleware. The migration must minimize downtime and use a pay-as-you-go model. Which AWS service should the company use to standardize the deployment of these applications?

Accepted Answer

AWS Application Migration Service. AWS Application Migration Service automates lift-and-shift migration of applications from on-premises to AWS, minimizing downtime and supporting heterogeneous environments with a pay-as-you-go model. Option A is wrong because AWS CloudFormation is for infrastructure as code, not for migrating applications. Option C is wrong because AWS Server Migration Service is deprecated and lacks the features of Application Migration Service. Option D is wrong because AWS Database Migration Service is specifically for databases, not general applications.

Answer

AWS CloudFormation

Answer

AWS Server Migration Service

Answer

AWS Database Migration Service

Question 3

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 4

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 5

A company is migrating a .NET application from Windows Server to AWS. The application uses SQL Server and needs to run on Amazon EC2. The company wants to reduce licensing costs. Which Amazon EC2 instance type should the company use?

Accepted Answer

T3. T3 instances are burstable and cost-effective for workloads with moderate CPU usage, making them ideal for reducing licensing costs for a .NET application on SQL Server. Option A (C5) is compute-optimized and may be overkill, increasing costs. Option C (A1) is ARM-based and may not support .NET. Option D (I3) is storage-optimized and not cost-effective for this scenario.

Answer

C5

Answer

A1

Answer

I3

Question 6

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.. ALB supports custom ports; you create a listener for port 8080. Option A is wrong because ALB does not require a specific security group port; you can configure any port. Option B is wrong because you cannot change the ALB's default ports; you add a listener. Option C is wrong because ALB itself does not need a public IP; it uses a DNS name.

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 7

A company is migrating a web application to AWS and wants to use Amazon ECS with Fargate. The application needs to store session state. Which AWS service should the company use for session state management?

Accepted Answer

Amazon ElastiCache for Redis. Amazon ElastiCache for Redis is a fully managed, in-memory caching service that provides low-latency access to session data, making it ideal for session state management in containerized applications on ECS Fargate. Option B (Amazon S3) is wrong because S3 is object storage with higher latency and is not designed for frequent, low-latency read/write operations required for session state. Option C (Amazon DynamoDB) is wrong because while it can be used, it is not the most common or recommended choice for session state due to higher latency compared to in-memory caching; ElastiCache is typically preferred. Option D (Amazon RDS) is wrong because RDS is a relational database service for persistent storage, not for transient session state with low-latency requirements.

Answer

Amazon S3

Answer

Amazon DynamoDB

Answer

Amazon RDS

Question 8

A company is migrating a virtual machine from on-premises to AWS. The VM runs Windows Server 2012 R2. The company wants to minimize changes to the VM. Which AWS service should the company use to migrate the VM?

Accepted Answer

AWS Server Migration Service. AWS Server Migration Service (SMS) is an agentless service that specializes in migrating virtual machines from on-premises environments to AWS with minimal changes to the VM configuration. Option B is incorrect because AWS Database Migration Service (DMS) is designed for database migrations, not entire VMs. Option C is incorrect because AWS CloudEndure Migration is a legacy service that has been superseded by AWS Application Migration Service. Option D is incorrect because although AWS Application Migration Service (MGN) can also migrate VMs, it typically requires installing an agent on the source VM, which introduces changes; SMS minimizes changes by using agentless replication.

Answer

AWS Database Migration Service

Answer

AWS CloudEndure Migration

Answer

AWS Application Migration Service

Question 9

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 (AWS DRS) provides continuous replication with near-zero RPO (typically seconds) and can meet an RTO of minutes. For an EC2 instance with an EBS volume, DRS replicates the entire server and enables rapid recovery in the same AWS Region or another Region, achieving the required 15-minute RTO and 5-minute RPO. Option A is incorrect because standard EC2 instances do not support synchronous replication between two instances—Multi-AZ is a feature of managed services like RDS, not for general EC2/EBS. Option B is wrong because EBS snapshots taken every 5 minutes achieve a 5-minute RPO, but restoring from a snapshot takes longer than 15 minutes, failing the RTO. Option C is wrong because an Auto Scaling group with warm standby does not guarantee stateful synchronous replication, and recovery time may exceed 15 minutes without additional orchestration.

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 10

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 11

A company is migrating a large number of files from on-premises to Amazon S3. The files are in a network-attached storage (NAS) system with a 1 Gbps connection to the internet. The company has a 2-week deadline to complete the migration. Which TWO services should the company use to accelerate the migration? (Choose TWO.)

Accepted Answer

AWS DataSync. (AWS DataSync) is correct because it can accelerate online transfers using parallel multi-threading and compression, making it suitable for migrating large numbers of files over a 1 Gbps connection within 2 weeks. Option C (AWS Snowball Edge) is correct because it provides a physical storage device that can handle large data volumes offline, bypassing network bandwidth limitations. Option B (AWS Transfer Family) is incorrect as it is designed for managed file transfer protocols, not for accelerating bulk migration. Option D (AWS Database Migration Service) is incorrect because it is intended for database migrations, not file migrations. Option E (AWS Direct Connect) is incorrect because it requires provisioning a dedicated connection, which may take longer than 2 weeks to set up and does not directly provide data migration acceleration.

Answer

AWS Transfer Family

Answer

AWS Database Migration Service

Answer

AWS Direct Connect

Question 12

A company is modernizing a legacy application by breaking it into microservices. The application currently uses a single relational database. The company wants to adopt a microservices architecture with separate databases per service. Which THREE patterns should the company consider? (Choose THREE.)

Accepted Answer

API Gateway. (API Gateway) is correct for routing requests to appropriate microservices. Option C (Database per Service) is correct as it aligns with the requirement for separate databases per service. Option D (Event Sourcing) is correct for maintaining data consistency across services. Option B (Shared Database) is incorrect because it would create coupling. Option E (CQRS) is incorrect because it is a pattern for read/write separation, not a primary pattern for microservices with separate databases.

Answer

Shared Database

Answer

Command Query Responsibility Segregation (CQRS)

Question 13

A company is migrating a web application to AWS and wants to use a content delivery network (CDN) to improve performance. Which TWO AWS services can be used together to achieve this? (Choose TWO.)

Accepted Answer

Amazon CloudFront. (Amazon CloudFront) is a content delivery network (CDN) that distributes content globally. Option E (Application Load Balancer) can be used as an origin for CloudFront to distribute traffic across multiple EC2 instances or containers. Option B (Amazon Route 53) is a DNS service, not a CDN. Option C (Amazon S3) is an object storage service that can serve as an origin for CloudFront but is not a CDN itself. Option D (AWS WAF) is a web application firewall, not a CDN.

Answer

Amazon Route 53

Answer

Amazon S3

Answer

AWS WAF

Question 14

A company is migrating a legacy on-premises .NET application to AWS. The application uses Windows Authentication and relies on Active Directory. The company wants to minimize code changes. Which solution should the architect recommend?

Accepted Answer

Deploy the application on Amazon EC2 instances joined to an AWS Managed Microsoft AD directory.. Deploy the application on Amazon EC2 instances joined to an AWS Managed Microsoft AD directory. This allows the application to use Windows Authentication with minimal code changes because the EC2 instances are domain-joined, enabling the application to authenticate users against Active Directory as it did on-premises. Option A is incorrect because AWS Systems Manager Parameter Store or Secrets Manager can store credentials but does not provide Windows Authentication integration. Option B is incorrect because Amazon WorkDocs is a document sharing service, not a compute platform. Option C is incorrect because Amazon Cognito user pools are designed for external user identities, not for Windows Authentication against Active Directory.

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 is migrating a 10 TB Oracle database to Amazon RDS for Oracle. The migration must have minimal downtime. The source database is running on-premises with limited bandwidth (50 Mbps). Which strategy should be used?

Accepted Answer

Use AWS Database Migration Service (DMS) with a full load and ongoing change data capture (CDC).. AWS Database Migration Service (DMS) with a full load and ongoing change data capture (CDC) minimizes downtime by continuously replicating changes from the source Oracle database to Amazon RDS for Oracle during the full load. After the full load completes, changes are applied to keep the target in sync, allowing a very brief cutover window. Over a 50 Mbps link, the initial 10 TB full load may take days, but CDC ensures minimal downtime at cutover. Option A (Snowball) is an offline method that requires exporting, shipping, and importing the database, which introduces significant downtime. Option B (Oracle GoldenGate) is a valid replication tool but adds complexity and cost; DMS is a managed service better integrated with AWS. Option D (export to flat files and import) requires taking the database offline for the export and import, causing substantial downtime.

Answer

Use AWS Snowball to transfer a full backup, then manually apply transaction logs.

Answer

Set up a VPN connection and use Oracle GoldenGate for replication.

Answer

Export the database to flat files, upload to Amazon S3, and import into RDS.
