AWS Trusted Advisor

Question 8

A company is migrating a legacy monolithic e-commerce platform to AWS. The platform consists of a Java-based web application, an Oracle database, and a file server storing product images. The company's migration requirements are: (1) minimize downtime during cutover, (2) reduce operational overhead for the database, (3) enable future migration to microservices. The current on-premises environment experiences high I/O latency for the file server. The company has already set up a VPN connection to AWS and has installed the AWS Application Discovery Service agent on all servers. During the assessment, you discover that the Oracle database is 2 TB and the file server holds 5 TB of images. The web application is tightly coupled with the database and uses stored procedures. You need to design the migration approach. Which combination of actions should be taken?

Accepted Answer

Use AWS DMS with ongoing replication to Amazon RDS for Oracle. Use S3 Transfer Acceleration to upload files to Amazon S3. Then cut over.. Option C is correct because using AWS DMS with ongoing replication minimizes downtime, RDS for Oracle reduces operational overhead, and S3 with Transfer Acceleration addresses high latency for file transfer. Option A is wrong because Snowball is offline and may cause longer cutover. Option B is wrong because EFS is not the best for image storage; S3 is better. Option D is wrong because refactoring to microservices during migration increases risk and complexity.

Answer

Use AWS Snowball Edge to transfer the database and files. After data is loaded, cut over DNS to AWS.

Answer

Use AWS DMS for continuous replication of the database to Amazon RDS for Oracle. Use AWS DataSync to copy files to Amazon EFS. Then cut over.

Answer

Refactor the application into microservices using Amazon ECS. Use Amazon RDS for Oracle and Amazon S3 for images. Then cut over gradually.

Question 9

A company is migrating a Windows-based .NET application to AWS. The application uses SQL Server for its database and stores documents on a Windows file share. The company wants to adopt a hybrid model initially, where the application runs on AWS but still connects to on-premises resources for legacy integration. The migration must use a phased approach: first move the compute to AWS, then the database, and finally the file storage. The company has high latency to the internet and wants to optimize data transfer. You have set up a Direct Connect connection. During the first phase, you migrate the web and application servers to Amazon EC2 Windows instances. You need to ensure that the EC2 instances can access the on-premises SQL Server and file share securely. Which combination of actions should be taken?

Accepted Answer

Place the EC2 instances in a private subnet. Create a VPN connection or use Direct Connect virtual interface to connect to on-premises. Configure security groups to allow traffic to on-premises SQL Server and file share.. Option A is correct because placing EC2 instances in a private subnet with a VPN or Direct Connect VIF to on-premises allows secure access. Option B is wrong because public subnet and internet gateway is not secure. Option C is wrong because ClassicLink is outdated and not recommended. Option D is wrong because NAT gateway is for outbound internet access, not for on-premises connectivity.

Answer

Place the EC2 instances in a private subnet with a NAT gateway. Use VPC peering to on-premises.

Answer

Place the EC2 instances in a public subnet. Use an internet gateway and configure security groups to allow inbound traffic from on-premises IPs.

Answer

Use Amazon EC2-Classic and link the instances to on-premises via ClassicLink.

Question 10

A small business is migrating its on-premises infrastructure to AWS. The current environment consists of two VMs running a LAMP stack (Linux, Apache, MySQL, PHP) and a separate file server. The business has limited IT staff and wants to minimize operational overhead. They also want to ensure high availability for the web application. The company has a modest budget and is looking for a cost-effective solution. You need to design the migration. Which approach should be taken?

Accepted Answer

Use AWS Elastic Beanstalk to deploy the web application. Use Amazon RDS for MySQL Multi-AZ for the database. Use S3 for file storage.. Option B is correct because using Elastic Beanstalk for the web tier and RDS for MySQL provides high availability with minimal management. Option A is wrong because two EC2 instances require more management. Option C is wrong because Lightsail is not highly available. Option D is wrong because ECS Fargate is more complex and costly for a small business.

Answer

Migrate the VMs to two EC2 instances in an Auto Scaling group behind an ALB. Use RDS for MySQL Multi-AZ.

Answer

Use Amazon Lightsail to host the entire application on a single instance with a managed database.

Answer

Containerize the application and run on Amazon ECS with Fargate. Use Amazon RDS for MySQL.

Question 11

A company is migrating an on-premises monolithic application to AWS. The application uses a legacy database that cannot be easily refactored. The company wants to minimize changes to the application code while gaining scalability and high availability. Which migration strategy should the architect recommend?

Accepted Answer

Rehost the application on Amazon EC2 and use Amazon RDS for the database.. Rehosting (lift-and-shift) involves moving the application and database to AWS infrastructure (EC2 and RDS) with minimal changes. This preserves the legacy database and allows the company to achieve scalability and HA using AWS features like Multi-AZ and Auto Scaling. Replatforming would require modifying the database engine; refactoring involves significant changes; and retiring removes the application.

Answer

Replatform the application to use AWS Elastic Beanstalk and Amazon DynamoDB.

Answer

Refactor the application to use a microservices architecture with Amazon Aurora.

Answer

Retire the application and replace it with a SaaS solution.

Question 12

A company is migrating a critical application to AWS and must ensure business continuity with a Recovery Time Objective (RTO) of 1 hour and a Recovery Point Objective (RPO) of 15 minutes. The application runs on a single on-premises server with a 500 GB disk. The current data changes at a rate of 10 MB per minute. Which solution will meet the RTO and RPO requirements with the least operational overhead?

Accepted Answer

Use AWS Application Migration Service (AWS MGN) to replicate the server continuously and automate cutover.. AWS Application Migration Service (AWS MGN) continuously replicates data with near-zero RPO and supports automated testing and cutover. It can achieve an RTO of less than 1 hour for a single server. AWS DMS is for database migration, not full server. AWS Backup has a minimum RPO of 1 hour for continuous backups. Manual snapshots cannot achieve 15-minute RPO due to the rate of change and manual intervention.

Answer

Use AWS Database Migration Service (AWS DMS) to replicate the database continuously.

Answer

Use AWS DataSync to replicate the server every 15 minutes to an EBS volume.

Answer

Take hourly snapshots of the server using AWS Backup and restore in a new EC2 instance.

Question 13

An organization is modernizing a legacy application by breaking it into microservices on AWS. The application processes customer orders and sends notifications. The team wants to decouple the order processing from the notification service to improve scalability. Which AWS service should they use to asynchronously pass messages between the services?

Accepted Answer

Amazon Simple Queue Service (Amazon SQS). Amazon SQS is a fully managed message queue service that enables decoupling of application components. SNS is pub/sub; EventBridge is event bus; Kinesis is for real-time streaming. For simple point-to-point async messaging, SQS is the best fit.

Answer

Amazon Kinesis Data Streams

Answer

Amazon EventBridge

Answer

Amazon Simple Notification Service (Amazon SNS)

Question 14

A company is migrating a multi-tier web application to AWS. The application consists of a stateless web tier and a stateful application tier that uses sticky sessions. The company wants to reduce operational overhead and improve elasticity. Which architecture should the solutions architect recommend?

Accepted Answer

Use an Application Load Balancer with sticky sessions for the web tier. Store session data in Amazon ElastiCache.. Using an Application Load Balancer (ALB) with sticky sessions (session affinity) enables the web tier to be stateless and scale horizontally. The application tier can use ElastiCache for session state storage, making it stateless as well. This reduces overhead and improves elasticity. NLB with EFS is not suitable for session state; ALB with DynamoDB is overkill; CloudFront does not support sticky sessions.

Answer

Use Amazon CloudFront with an origin load balancer and store session data in the web tier's local storage.

Answer

Use an Application Load Balancer with cross-zone load balancing and store session data in Amazon DynamoDB.

Answer

Use a Network Load Balancer with instance targets and Amazon EFS to share session data.

Question 15

A company is migrating a legacy .NET application to AWS. The application currently uses Windows Authentication and a SQL Server database. The company wants to reduce licensing costs and use managed services where possible. The migration should minimize code changes. Which combination of services meets these requirements?

Accepted Answer

AWS Elastic Beanstalk for the .NET application, Amazon RDS for SQL Server, and AWS Managed Microsoft AD. AWS Managed Microsoft AD provides Windows Authentication compatibility. Amazon RDS for SQL Server is a managed database service that reduces operational overhead and licensing costs compared to self-managed SQL Server. AWS Elastic Beanstalk supports .NET applications. This combination minimizes code changes. Lambda does not support .NET Windows Authentication natively; DynamoDB is not compatible; EC2 does not reduce licensing costs.

Answer

Amazon EC2 instances with SQL Server installed and AWS Directory Service for AD

Answer

AWS Lambda for the application logic and Amazon DynamoDB for the database

Answer

Amazon ECS with Windows containers, Amazon RDS for SQL Server, and AWS SSO
