Question 2

A company is migrating a legacy three-tier application to AWS. The application consists of a web tier, an application tier, and a database tier. The company wants to minimize downtime during the migration and ensure that the application remains available if a single Availability Zone fails. The database is currently running on a physical server and cannot be modified. Which migration approach should a solutions architect recommend?

Accepted Answer

Use AWS Application Migration Service (MGN) to replicate the application servers to AWS, launch them in multiple Availability Zones behind an Application Load Balancer, and replicate the database to an EC2 instance in a second Availability Zone using native replication.. Application Migration Service replicates the application servers to AWS with minimal downtime. Deploying them across multiple Availability Zones behind an Application Load Balancer provides high availability. Replicating the unmodified database to an EC2 instance in a second AZ using native replication maintains the database as-is while offering failover. This approach satisfies both the minimal downtime and high availability requirements.

Answer

Use AWS Database Migration Service (DMS) to migrate the database to Amazon RDS, and deploy the web and application tiers on EC2 instances across multiple Availability Zones with an Application Load Balancer.

Answer

Use AWS Application Migration Service (MGN) to replicate the entire application to AWS, launch it in a single Availability Zone, and use Amazon RDS for the database.

Answer

Use AWS Server Migration Service (SMS) to migrate the application servers to Amazon EC2, and use Amazon RDS Multi-AZ for the database.

Question 3

A company is migrating a high-traffic web application from on-premises to AWS. The application consists of a stateless web tier and a stateful session store. The company wants to modernize the session store to a managed AWS service that provides high availability and automatic scaling. The application currently uses an in-memory data grid with a proprietary protocol. Which two actions should a solutions architect take to meet these requirements? (Choose two.)

Accepted Answer

Modify the application to use the Redis protocol for session storage.. Migrating the session store to Amazon ElastiCache for Redis with cluster mode enabled provides a managed, scalable, and highly available in-memory data store. Modifying the application to use the Redis protocol is required to communicate with ElastiCache.

Question 4

A company is modernizing a legacy monolithic application by breaking it into microservices. The application currently uses a single Oracle database. The company wants to migrate to a microservices architecture on AWS with minimal disruption. Each microservice should have its own database, and the databases should be highly available and scalable. Which migration strategy should a solutions architect recommend?

Accepted Answer

Use AWS Schema Conversion Tool (AWS SCT) to convert the Oracle schema to Amazon Aurora PostgreSQL, and then split the schema into separate databases for each microservice.. Using AWS Schema Conversion Tool to convert the Oracle schema to Amazon Aurora PostgreSQL automates much of the migration effort. Aurora PostgreSQL provides high availability, scalability, and managed operations. Splitting the converted schema into separate databases per microservice follows the database-per-service pattern, enabling independent scaling and reducing coupling, which is essential for a successful microservices modernization.

Answer

Keep the single Oracle database on Amazon RDS for Oracle, and have all microservices share it, using separate schemas for isolation.

Answer

Migrate the Oracle database to Amazon DynamoDB, and redesign each microservice to use DynamoDB tables with single-table design.

Answer

Use AWS Database Migration Service to replicate the Oracle database to multiple Amazon RDS for Oracle instances, one per microservice, and refactor the application to write to all instances.

Question 5

A company is modernizing a legacy monolithic application by migrating it to a microservices architecture on AWS. The application currently uses a single Oracle database. The company wants to decompose the database into smaller, independently deployable services. The application has high read throughput and requires strong consistency for write operations. The company also wants to minimize operational overhead for database management. Which two strategies should a solutions architect recommend to achieve these goals? (Choose two.)

Accepted Answer

Use Amazon Aurora PostgreSQL with multiple read replicas to offload read traffic, and use AWS Database Migration Service (AWS DMS) to migrate the data.. Amazon Aurora PostgreSQL offers a managed, scalable database with read replicas for high read throughput and a single writer for strong consistency. AWS DMS enables continuous replication from Oracle, minimizing downtime during migration. Together, these services reduce operational overhead and support the decomposition of the monolithic database into microservices with independent data stores.

Answer

Use Amazon ElastiCache for Redis to cache all read queries, and use Amazon RDS for PostgreSQL with a single instance for writes.

Answer

Use Amazon RDS for Oracle with Multi-AZ deployment and add read replicas to handle read traffic, and use AWS Schema Conversion Tool (AWS SCT) to convert the schema.

Answer

Decompose the database into multiple microservices, each with its own Amazon DynamoDB table, and use DynamoDB Accelerator (DAX) for read caching.

Question 6

A company is migrating a legacy application to AWS. The application runs on a physical server with a custom Linux kernel module that is not supported on AWS. The company wants to rehost the application to Amazon EC2 with minimal changes. Which approach should they take?

Accepted Answer

Refactor the application to remove the custom kernel module and use a supported AWS service or library.. The correct approach is to refactor the application to remove the custom kernel module. AWS EC2 does not support custom kernel modules that require direct hardware access or unsupported kernel modifications. Refactoring allows the application to use AWS-supported services or user-space libraries, ensuring compatibility and reliability on EC2. Other options either do not address the kernel module issue or are deprecated.

Answer

Use AWS Outposts to run the application on dedicated hardware that supports the custom kernel module.

Answer

Use AWS Application Migration Service to replicate the server and launch an EC2 instance with the same kernel.

Answer

Use AWS Server Migration Service to perform an agentless migration of the server to EC2.

Question 7

A retail company wants to migrate an on-premises Microsoft SQL Server database to Amazon RDS for SQL Server. The database is 2 TB and the company has limited network bandwidth, but it can tolerate a maintenance window of several days. The company wants to minimize the cutover time and avoid shipping physical media. Which approach should a solutions architect recommend?

Accepted Answer

Use AWS Database Migration Service with a full load plus ongoing replication task, then stop replication and cut over the application during a short maintenance window.. AWS DMS performs a full load followed by change data capture, so the 2 TB bulk transfer happens while the source remains online and only incremental changes need to be applied at cutover. This minimizes the final maintenance window despite limited bandwidth and avoids shipping physical media.

Answer

Use AWS Application Migration Service to replicate the database server, then launch a cutover instance and point the application at the new EC2 instance running SQL Server.

Answer

Take a full backup to an Amazon S3 bucket using AWS Storage Gateway, restore it to Amazon RDS for SQL Server, and repeat the process during the cutover window.

Answer

Configure an Amazon RDS for SQL Server read replica in a second Availability Zone and promote it during the cutover window.

Question 8

A company is migrating a containerized application from an on-premises Kubernetes cluster to Amazon Elastic Kubernetes Service (Amazon EKS). The application requires persistent storage for a high-performance database and must be highly available across multiple Availability Zones. The company also needs to minimize operational overhead for managing the Kubernetes control plane. Which two actions should a solutions architect take to meet these requirements? (Choose two.)

Accepted Answer

Deploy the application on a managed node group with nodes spread across multiple Availability Zones.. Using a managed node group across multiple Availability Zones reduces operational overhead and ensures high availability. The Amazon EBS CSI driver with gp3 volumes and multi-Attach enables high-performance, persistent block storage suitable for a database, with the ability to attach to multiple nodes for failover. Together, these actions meet the requirements for performance, availability, and reduced management overhead.
