Question 1

A company is migrating a monolithic Java application to AWS. The application uses a shared file system for storing user-uploaded documents. The company wants to refactor the application to use a microservices architecture with decoupled storage and compute. The application currently writes files to a local directory and serves them via a web server. Which AWS service should be used to store the documents to enable stateless compute and independent scaling?

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

Accepted Answer

Amazon S3. Amazon S3 provides durable, scalable object storage that decouples storage from compute, enabling a stateless microservices architecture. Other options like EFS, EBS, and FSx are file or block storage solutions that require mounting and are not optimized for decoupled, independently scaling services. S3 also integrates with other AWS services for event-driven processing.

Answer

Amazon FSx for Windows File Server

Answer

Amazon Elastic File System (Amazon EFS)

Answer

Amazon Elastic Block Store (Amazon EBS)

Question 2

A company is migrating 50 on-premises VMware virtual machines to AWS. The migration must complete within a four-week maintenance window, and the company wants to minimize application changes. The VMs run a mix of Windows and Linux. Which AWS service should the company use to migrate these VMs to Amazon EC2?

Accepted Answer

AWS Application Migration Service (AWS MGN). AWS Application Migration Service (MGN) is purpose-built for lift-and-shift migrations of physical, virtual, or cloud servers to EC2. It supports Windows and Linux, uses block-level replication, and enables test launches and cutover with minimal downtime. The other services address data-only movement or legacy tooling, not full server migration.

Answer

AWS Database Migration Service (AWS DMS)

Answer

AWS Server Migration Service (AWS SMS)

Answer

AWS DataSync

Question 3

A company is migrating an on-premises Oracle database to Amazon Aurora PostgreSQL. The database is 5 TB and must be migrated with minimal downtime. The company requires continuous replication of changes during the migration and the ability to cut over within a 1-hour maintenance window. Which combination of AWS services should be used to achieve this?

Accepted Answer

AWS Database Migration Service (AWS DMS) with ongoing replication and AWS Schema Conversion Tool (AWS SCT). For heterogeneous migrations with minimal downtime, AWS DMS with ongoing replication and AWS SCT is the correct combination. DMS handles data migration and change data capture, while SCT converts the schema. Other options either lack ongoing replication, are not designed for data migration, or are incompatible with the target database engine.

Answer

Native Oracle Data Guard with AWS Direct Connect

Answer

AWS Schema Conversion Tool (AWS SCT) with continuous replication

Answer

AWS Database Migration Service (AWS DMS) with full load only

Question 4

A company is migrating a legacy on-premises application to AWS. The application runs on a physical server and uses a locally attached tape library for nightly backups. The company wants to eliminate tape management and store backups in Amazon S3. The backup software supports the iSCSI protocol. Which solution should a solutions architect recommend?

Accepted Answer

Deploy an AWS Storage Gateway tape gateway and configure the backup software to use the virtual tape library.. AWS Storage Gateway tape gateway provides a virtual tape library that integrates with existing backup software over iSCSI. Virtual tapes are stored in Amazon S3 and can be archived to Amazon S3 Glacier or Deep Archive, eliminating physical tape handling while preserving the backup application's workflow. Other gateway types or DataSync do not provide a tape interface.

Answer

Use AWS DataSync to replicate the backup server's local disk to Amazon S3.

Answer

Deploy an AWS Storage Gateway file gateway and mount it as an NFS share on the backup server.

Answer

Deploy an AWS Storage Gateway volume gateway in stored mode and present it as an iSCSI target to the backup server.

Question 5

A financial services company is migrating a mainframe COBOL application to AWS. The application writes files to a VSAM dataset and is invoked by a CICS transaction manager. The company wants to preserve business logic with minimal rewrite while moving to a managed runtime. Which migration strategy and AWS service combination best meets these requirements?

Accepted Answer

Replatform the COBOL application with AWS Mainframe Modernization using the Blu Age automated refactoring pattern, deploying to a managed runtime environment. AWS Mainframe Modernization is purpose-built for moving mainframe workloads, offering automated refactoring with Blu Age and replatforming with Micro Focus. The Blu Age pattern transforms COBOL, CICS, and VSAM artifacts into modern code that runs on a managed runtime, which preserves business logic and minimizes rewrite. The other approaches either cannot replicate CICS transaction semantics, cannot replicate a mainframe LPAR, or abandon the existing logic entirely.

Answer

Repurchase a SaaS core banking product and re-implement the COBOL business logic through the vendor's configuration tools

Answer

Rehost the application with AWS Application Migration Service (AWS MGN) to Amazon EC2 and keep the mainframe emulator on the instance

Answer

Replatform the COBOL application to AWS Lambda using a custom runtime that emulates CICS transaction semantics

Question 6

A company runs a high-traffic web application on physical servers in its own data center. The servers use a proprietary TCP-based protocol on port 9000 that cannot be changed, and the application stores session data in local memory. The company wants to migrate the application to AWS with minimal code changes while enabling horizontal scaling and high availability. Which combination of AWS services should a solutions architect recommend to meet these requirements?

Accepted Answer

Use a Network Load Balancer with a TCP listener on port 9000, and store session data in Amazon ElastiCache for Redis.. The proprietary TCP protocol on port 9000 requires a Layer 4 load balancer. A Network Load Balancer supports TCP listeners on any port, preserving the protocol without code changes. Externalizing session state to ElastiCache for Redis removes the dependency on local memory, enabling horizontal scaling. This combination provides high availability and minimal modification.

Answer

Use an Application Load Balancer with sticky sessions enabled, and store session data in Amazon ElastiCache for Redis.

Answer

Use a Network Load Balancer with a UDP listener on port 9000, and store session data in Amazon ElastiCache for Memcached.

Answer

Use an Application Load Balancer with a TCP listener on port 9000, and store session data in Amazon DynamoDB.

Question 7

A company is migrating a 40 TB on-premises Oracle database to Amazon Aurora PostgreSQL. The database must remain fully operational during the migration, and the cutover must complete within a 30-minute maintenance window. The company requires continuous data replication until the final switchover. Which migration approach should a solutions architect recommend?

Accepted Answer

Use AWS Database Migration Service (AWS DMS) with ongoing replication, then perform a cutover after the replication lag is near zero.. AWS DMS with ongoing replication is purpose-built for heterogeneous migrations that require minimal downtime. It reads ongoing changes from Oracle and applies them to Aurora PostgreSQL, keeping the target nearly current. When replication lag is low, the application can be switched over quickly, satisfying the 30-minute cutover requirement while the source remains fully available throughout the migration.

Answer

Use AWS Schema Conversion Tool (AWS SCT) to convert the schema, then use native Oracle tools to replicate ongoing changes to Aurora PostgreSQL.

Answer

Take a full export of the Oracle database using Oracle Data Pump, transfer it to Amazon S3, and import it into Aurora PostgreSQL.

Answer

Configure Oracle Active Data Guard to replicate to an Amazon RDS for Oracle read replica, then promote the replica and migrate to Aurora PostgreSQL.

Question 8

A company is migrating a high-traffic web application to AWS. The application currently runs on physical servers in a colocation facility and uses a custom session state mechanism stored in a local Redis instance on each server. The company wants to modernize the application to be highly available and scalable on AWS with minimal code changes. Which solution meets these requirements?

Accepted Answer

Deploy the application on Amazon EC2 instances behind an Application Load Balancer, and migrate session state to Amazon ElastiCache for Redis with cluster mode enabled.. Migrating session state to Amazon ElastiCache for Redis preserves the existing Redis API usage, requiring only a configuration change to point to the new endpoint. ElastiCache provides high availability with automatic failover and scalability through cluster mode. Combined with an Application Load Balancer and EC2 Auto Scaling, the application becomes stateless, highly available, and scalable with minimal code modifications.

Answer

Deploy the application on Amazon ECS with Fargate, and use Amazon EFS to store session files that are shared across all tasks.

Answer

Deploy the application on Amazon EC2 instances in an Auto Scaling group, and use an Application Load Balancer with sticky sessions enabled to keep users on the same instance.

Answer

Migrate the application to AWS Lambda with Amazon API Gateway, and store session data in Amazon DynamoDB using a new session management library.

Question 9

A financial services company is migrating a legacy on-premises Java application to AWS. The application uses an Oracle database and is deployed on WebLogic Server. The company wants to modernize the application by moving to a microservices architecture on AWS. The migration must minimize downtime and ensure data consistency during the transition. Which two strategies should be used to achieve these goals? (Choose two.)

Accepted Answer

Implement a strangler fig pattern by gradually replacing components of the monolith with microservices, using Amazon API Gateway to route traffic between old and new components.. The strangler fig pattern enables incremental decomposition of the monolith into microservices, while API Gateway routes traffic, allowing coexistence and minimal downtime. AWS DMS with ongoing replication ensures the database is continuously synchronized during migration, enabling a cutover with minimal lag. Together, these strategies achieve modernization with data consistency and low downtime.

Answer

Decompose the monolith into microservices using AWS App2Container to containerize the WebLogic application, then deploy to Amazon ECS with AWS Fargate.

Answer

Migrate the application to AWS Elastic Beanstalk with a Tomcat platform and use AWS CodeDeploy for blue/green deployments to achieve zero downtime.

Answer

Use AWS Migration Hub to orchestrate the migration and AWS Server Migration Service (SMS) to replicate the WebLogic servers to Amazon EC2, then refactor in place.

Question 10

A media company is migrating its on-premises rendering farm to AWS. The rendering application uses a shared file system that must be accessible by hundreds of EC2 instances simultaneously. The file system must provide high throughput and low latency, and support POSIX permissions. The company wants to minimize changes to the application. Which AWS storage service should they use?

Accepted Answer

Amazon FSx for Lustre. Amazon FSx for Lustre is purpose-built for high-performance computing workloads such as rendering, providing the low latency, high throughput, and POSIX compliance needed. It can be accessed by many EC2 instances simultaneously and integrates with S3. Other file systems either lack the performance or are not POSIX-compliant for Linux workloads.

Answer

Amazon FSx for Windows File Server

Answer

Amazon S3 with AWS Transfer Family

Answer

Amazon Elastic File System (EFS) Standard

Question 11

A company is migrating a high-traffic web application to AWS. The application currently runs on physical servers in a data center and uses a shared storage area network (SAN) for storing static assets. The company wants to modernize the application to be highly available and scalable across multiple Availability Zones. The static assets are accessed frequently and must be served with low latency globally. Which solution should the company implement?

Accepted Answer

Store static assets in Amazon S3 and use Amazon CloudFront for global content delivery.. Storing static assets in Amazon S3 and serving them via Amazon CloudFront provides a highly available, scalable, and globally distributed solution. S3 offers durable storage, and CloudFront caches content at edge locations for low latency. Other options do not provide global content delivery or are not suited for static asset serving at scale.

Answer

Deploy Amazon EFS in multiple Availability Zones and mount it to EC2 instances.

Answer

Use Amazon EBS volumes replicated across Availability Zones with Amazon EC2 Auto Scaling.

Answer

Use AWS Storage Gateway to cache on-premises SAN data to AWS.

Question 12

A company is migrating 400 on-premises VMware virtual machines to AWS. The migration team wants to use the AWS Application Migration Service (AWS MGN) to replicate servers continuously to a staging area and then launch test and cutover instances. The company's security policy requires that all replicated data remain encrypted with customer-managed keys and that the replication traffic never traverse the public internet. The on-premises network is already connected to a VPC through an AWS Site-to-Site VPN. Which combination of actions should the migration team take to meet these requirements?

Accepted Answer

Deploy AWS MGN replication agents, create a staging Area subnet in the target VPC, and configure the replication settings to use the Site-to-Site VPN for data replication; specify a customer-managed AWS KMS key for EBS encryption.. AWS MGN replicates source servers continuously to a staging Area subnet using replication agents and lightweight replication servers, and the launch settings determine EBS encryption. Placing the staging Area subnet in the VPC reachable over the existing Site-to-Site VPN keeps replication traffic private, and selecting a customer-managed AWS KMS key in the replication template satisfies both encryption and key-ownership requirements without introducing unrelated services.

Answer

Deploy AWS MGN replication agents and configure them to replicate to an Amazon S3 bucket using AWS Snowball Edge devices for the initial seed, then rely on S3 default encryption with Amazon S3 managed keys.

Answer

Deploy AWS MGN replication agents and use AWS DataSync to copy VM disk images to Amazon FSx for Windows File Server in the target VPC, then launch cutover instances from the file share.

Answer

Deploy AWS MGN replication agents and configure the replication settings to use the public AWS MGN service endpoints; enable EBS encryption with the default AWS managed key to reduce operational overhead.

Question 13

A company is migrating a high-traffic web application from on-premises to AWS. The application uses a shared file system for storing user uploads, and the company wants to ensure high availability and durability across multiple Availability Zones. The migration must be completed with minimal changes to the application code. Which AWS service should be used for the shared file system?

Accepted Answer

Amazon EFS with a mount target in each Availability Zone and a lifecycle policy to move infrequent access files to EFS IA.. Amazon EFS is a fully managed, elastic NFS file system that can be mounted on EC2 instances across multiple AZs, providing high availability and durability. It requires no application changes since it presents a standard file system interface. The lifecycle policy helps manage costs by moving infrequently accessed files to a lower-cost storage class.

Answer

Amazon FSx for Lustre with a linked S3 bucket for durability.

Answer

Amazon FSx for Windows File Server with Multi-AZ deployment.

Answer

Amazon S3 with a mounted file system using s3fs-fuse on each web server.

Question 14

A company is modernizing an on-premises Java application by moving it to containers on Amazon EKS. The application reads configuration from environment-specific property files and stores user-uploaded documents on a locally mounted NFS share. The company wants the containerized application to be portable across clusters and environments, and it must not require rebuilding the container image per environment. Which two changes should a solutions architect make to meet these requirements? (Choose two.)

Accepted Answer

Store the environment-specific configuration in AWS Systems Manager Parameter Store or AWS Secrets Manager and inject the values into the pods as environment variables or mounted files at runtime. Portability across clusters and environments requires that environment-specific values and shared state live outside the image. Externalizing configuration into Parameter Store or Secrets Manager and injecting it at runtime keeps a single image valid everywhere, while Amazon EFS with the EFS CSI driver reproduces the shared NFS semantics the application expects. Baking configuration into images or using node-local storage both break portability and shared access.

Answer

Move the uploaded documents into the container image and write new uploads to the pod's ephemeral writable layer

Answer

Bake the environment-specific property files into the container image during the CI build for each environment

Answer

Replace the NFS share with an Amazon EBS volume attached to each node and expose it to the pods with a hostPath volume

Question 15

A company is migrating a legacy on-premises application to AWS. The application uses a shared file system that must be accessible from multiple Amazon EC2 instances across two Availability Zones. The file system must provide high throughput and support POSIX permissions. Which AWS service should the company use?

Accepted Answer

Amazon Elastic File System (Amazon EFS). Amazon EFS is a shared, POSIX-compliant file system that can be mounted across multiple EC2 instances in multiple Availability Zones. It provides high throughput and is fully managed. FSx for Windows is for Windows workloads, S3 is object storage, and EBS Multi-Attach is limited to a single Availability Zone and is block storage.

Answer

Amazon Elastic Block Store (Amazon EBS) Multi-Attach

Answer

Amazon FSx for Windows File Server

Answer

Amazon S3 with mounted file system using s3fs
