Question 4

A company is migrating a legacy on-premises application to AWS. The application uses a proprietary database that runs on a single Windows server. The company wants to minimize downtime and avoid re-architecting the database. Which migration strategy should the solutions architect recommend?

Accepted Answer

Rehost using AWS Application Migration Service (CloudEndure). Rehost (lift-and-shift) is the best option because it moves the application without changes, minimizing downtime and avoiding re-architecture. Replatforming would require some changes, and re-architecting would involve significant rework. Retire is not applicable.

Answer

Retire the application and replace it with a SaaS solution

Answer

Re-architect the application to use Amazon DynamoDB

Answer

Replatform by migrating the database to Amazon RDS for SQL Server

Question 5

A company is migrating a multi-tier web application to AWS. The application includes an Apache web server and a MySQL database. The operations team needs to scale the web tier based on CPU utilization while maintaining a static IP for the database. Which combination of AWS services should the solutions architect use?

Accepted Answer

Auto Scaling group for web tier with an Application Load Balancer; Amazon EC2 instance for MySQL database with an Elastic IP. An Auto Scaling group with an Application Load Balancer provides scaling for web servers. An Elastic IP on an EC2 instance provides a static IP for the database. RDS does not support Elastic IP directly.

Answer

Auto Scaling group for web tier with a Network Load Balancer; Amazon RDS for MySQL database with a static Elastic IP

Answer

Auto Scaling group for web tier with an Application Load Balancer; Amazon RDS for MySQL database with a static Elastic IP

Answer

Auto Scaling group for web tier with a Classic Load Balancer; Amazon EC2 instance for MySQL database with an Elastic IP

Question 6

A company plans to migrate 50 on-premises virtual machines (VMs) to AWS. The migration must be completed within 2 weeks. The VMs run various operating systems and have a total data size of 10 TB. The company has a low-bandwidth internet connection (50 Mbps). Which migration approach minimizes the time to transfer the data?

Accepted Answer

Use AWS Snowball Edge to transfer the VM images physically. AWS Snowball Edge is a physical device that can handle large data transfers over low-bandwidth connections. AWS Application Migration Service relies on network replication, which would be too slow. Direct Connect would require longer setup time. VPN is also network-based and slow.

Answer

Set up an AWS Direct Connect connection to increase bandwidth

Answer

Create a VPN tunnel to AWS and use rsync to copy the data

Answer

Use AWS Application Migration Service to replicate the VMs continuously

Question 7

A company is migrating a critical application to AWS using the 7 Rs migration strategy. The application has a monolithic architecture and runs on a single large on-premises server. The business wants to reduce operational overhead but cannot afford any downtime. Which strategy should the solutions architect recommend?

Accepted Answer

Rehost the application using AWS Application Migration Service. Rehost (lift-and-shift) moves the application as-is to minimize risk and downtime. Replatforming would require changes that could introduce downtime. Refactor/Re-architect would be too invasive. Retire is not applicable as the application is critical.

Answer

Retire the application and replace it with a SaaS solution

Answer

Replatform the application to use AWS managed services

Answer

Refactor / Re-architect the application into microservices

Question 8

A company is migrating an on-premises Oracle database to Amazon RDS for Oracle. The database is 2 TB in size and the company has a 1 Gbps AWS Direct Connect connection. They need to minimize downtime. Which approach should the solutions architect recommend?

Accepted Answer

Use AWS DMS with full load followed by ongoing replication using change data capture (CDC). AWS Database Migration Service (DMS) with change data capture (CDC) allows continuous replication and minimal downtime. Export/import would cause downtime. AWS Schema Conversion Tool (SCT) is for schema conversion, not data migration. Snowball is for offline data transfer and would delay the process.

Answer

Export the database using Oracle Data Pump and import into RDS

Answer

Use AWS Snowball Edge to transfer the database files and then restore to RDS

Answer

Use AWS Schema Conversion Tool to convert the schema and AWS DMS for data migration without CDC

Question 9

A company has a legacy application that runs on Windows Server 2008 R2 on-premises. The application is no longer supported by the vendor, but the company still needs to run it for compliance reasons. They are migrating to AWS and want to minimize changes. What should the solutions architect recommend?

Accepted Answer

Use an Amazon EC2 instance with a Windows Server 2008 R2 BYOL AMI. Using a Windows Server 2008 R2 BYOL AMI allows the company to run the legacy OS without changes. AWS does not provide mainstream support for 2008 R2, but BYOL allows it. Refactoring or replacing the application would require changes. Upgrading the OS might break the application.

Answer

Refactor the application to run on a supported Windows Server version

Answer

Upgrade to Windows Server 2019 and use AWS License Manager

Answer

Replace the application with a SaaS alternative

Question 10

A company is migrating a stateful web application to AWS. The application currently runs on a single on-premises server and uses local storage for session data. The company wants to make the application highly available and scalable. What should the solutions architect do?

Accepted Answer

Migrate session data to Amazon ElastiCache or DynamoDB, then use an Auto Scaling group behind an ALB. Moving session state to ElastiCache or DynamoDB makes the application stateless, enabling Auto Scaling. Sticky sessions on an ALB are a workaround but do not provide full statelessness. Using a larger instance does not provide high availability. Multi-AZ RDS for session data is not ideal for high-frequency session access.

Answer

Store session data in a Multi-AZ Amazon RDS database and use Route 53 with health checks

Answer

Use an Application Load Balancer with sticky sessions and an Auto Scaling group

Answer

Use a larger EC2 instance to handle all traffic and take regular snapshots

Question 11

A company is migrating an on-premises .NET application to AWS. The application uses a SQL Server database with a large number of stored procedures and triggers. The company wants to reduce licensing costs by moving to an open-source database. Which AWS service should the solutions architect use to automate the database conversion?

Accepted Answer

AWS Schema Conversion Tool (SCT). AWS Schema Conversion Tool (SCT) automates the conversion of database schema and code to a target database like PostgreSQL or MySQL. DMS handles data migration, not schema conversion. App2Container is for containerizing applications. CloudEndure is for server migration.

Answer

AWS Database Migration Service (DMS)

Answer

AWS App2Container

Answer

AWS Application Migration Service (CloudEndure)

Question 12

A company is migrating a batch processing workload to AWS. The workload runs daily on a single on-premises server and takes 6 hours to complete. The company wants to reduce processing time and cost. Which approach should the solutions architect recommend?

Accepted Answer

Use AWS Batch to run the workload in parallel on multiple compute resources. AWS Batch can orchestrate parallel processing across multiple EC2 or Fargate resources, reducing time. A single larger instance may not reduce time as much as parallel processing. Lambda has a 15-minute execution limit. Step Functions alone does not provide compute.

Answer

Use AWS Lambda with a 6-hour timeout

Answer

Use AWS Step Functions to orchestrate the workload sequentially

Answer

Use a single larger EC2 instance with more vCPUs

Question 13

A company is migrating a legacy application to AWS. The application currently runs on a single on-premises server with a local MySQL database. The company wants to minimize changes and reduce operational overhead. Which TWO strategies should the solutions architect recommend? (Select TWO.)

Accepted Answer

Replatform the database to Amazon RDS for MySQL. Rehost (lift-and-shift) minimizes changes by moving the application as-is. Replatforming the database to RDS reduces operational overhead by offloading database management. Retire is not applicable. Refactor would require changes. Repurchase involves buying new software.

Answer

Refactor the application to use microservices

Answer

Retire the application

Answer

Repurchase a SaaS alternative

Question 14

A company is migrating a multi-tier e-commerce application to AWS. The application consists of a web tier, an application tier, and a MySQL database tier. The company wants to improve scalability and availability while reducing administrative overhead. Which THREE actions should the solutions architect take? (Select THREE.)

Accepted Answer

Migrate the MySQL database to Amazon RDS Multi-AZ. Using an ALB and Auto Scaling for web tier improves scalability and availability. Migrating to RDS Multi-AZ reduces overhead and provides high availability. ElastiCache for session caching improves performance, but is not the only option for scalability. EFS is for shared file storage, not needed. Using Spot Instances for all tiers may cause interruptions.

Answer

Use Amazon EFS for shared storage between web instances

Answer

Use Spot Instances for all EC2 instances to reduce costs

Question 15

A company is migrating an on-premises data center to AWS. The company has a large amount of data (50 TB) that needs to be transferred quickly. The internet connection is limited to 100 Mbps. Which TWO methods should the solutions architect consider for the initial data transfer? (Select TWO.)

Accepted Answer

Use AWS Snowball Edge devices to ship the data. AWS Snowball Edge is a physical device for offline data transfer, suitable for large data over slow networks. AWS DataSync can transfer data over the internet but is limited by bandwidth; however, it can be used for incremental transfers after initial load. Direct Connect may take time to provision. VPN is slow. S3 Transfer Acceleration speeds up transfers over the internet but still limited by bandwidth.

Answer

Use a VPN connection and rsync

Answer

Set up an AWS Direct Connect connection

Answer

Use Amazon S3 Transfer Acceleration
