Q11A manufacturing company needs to migrate several applications to AWS and wants to automate the migration process for its Windows-based servers. Which AWS service should be used?
✓ Correct answer: B. AWS Application Migration Service
AWS Application Migration Service (formerly CloudEndure Migration) automates the lift-and-shift migration of applications from physical, virtual, or cloud infrastructure to AWS. It's specifically designed for server migrations with minimal downtime and is ideal for Windows-based servers.
Q12A company is migrating a legacy application with tightly coupled components to AWS. The application currently uses a shared database for component communication. Which modernization approach should be recommended?
✓ Correct answer: A. Implement an event-driven architecture using Amazon EventBridge
Implementing an event-driven architecture using Amazon EventBridge allows components to communicate asynchronously through events rather than direct coupling through a shared database. This pattern improves scalability, resilience, and maintainability by decoupling the components and enabling them to evolve independently.
Q13A financial services company wants to modernize its batch processing system when migrating to AWS. The current system runs large jobs overnight that often take hours to complete. Which AWS service would best improve this process?
✓ Correct answer: D. AWS Batch
AWS Batch enables developers to run batch computing workloads on the AWS Cloud. It dynamically provisions the optimal quantity and type of compute resources based on the volume and requirements of the batch jobs. For financial batch processing, it can significantly reduce processing time through parallelization and optimal resource allocation.
Q14A company is migrating from on-premises Oracle databases to AWS and wants to optimize costs while maintaining compatibility with existing applications. Which migration approach should be recommended?
✓ Correct answer: C. Migrate to Amazon Aurora PostgreSQL using AWS Schema Conversion Tool
Migrating from Oracle to Amazon Aurora PostgreSQL using AWS Schema Conversion Tool and AWS DMS allows organizations to move away from expensive Oracle licensing while maintaining compatibility through PostgreSQL's Oracle compatibility features. Aurora provides better performance and lower costs compared to commercial databases.
Q15An organization is migrating a content management system with millions of images to AWS. Which storage service would be most cost-effective for this workload?
✓ Correct answer: B. Amazon S3 with appropriate storage classes
Amazon S3 is the most cost-effective solution for storing millions of images in a content management system. It provides virtually unlimited storage, built-in scalability, and various storage classes to optimize costs. S3 also integrates well with Amazon CloudFront for efficient content delivery and has robust lifecycle policies to automatically move less-accessed content to cheaper storage tiers.
Q16A company needs to migrate a large on-premises Hadoop cluster to AWS. Which service should be recommended to minimize operational overhead while maintaining compatibility?
✓ Correct answer: A. Amazon EMR
Amazon EMR is a cloud-native big data platform for processing vast amounts of data using open-source tools such as Apache Hadoop, Apache Spark, and others. For migrating a Hadoop cluster, EMR provides a managed service that eliminates operational overhead while maintaining compatibility with existing Hadoop workloads.
Q17A media company is migrating its web application to AWS and wants to implement an architecture that can handle unpredictable traffic spikes. Which service combination would best support this requirement?
✓ Correct answer: D. Amazon EC2 Auto Scaling with Application Load Balancer
The combination of Amazon EC2 Auto Scaling and an Application Load Balancer provides automatic scaling of EC2 instances based on demand, while the ALB distributes incoming traffic across multiple targets in multiple Availability Zones. This combination ensures high availability and elasticity to handle unpredictable traffic spikes common in media applications.
Q18A company is migrating from a monolithic application to a microservices architecture on AWS and needs to implement secure service-to-service communication. Which AWS service should be used?
✓ Correct answer: C. AWS App Mesh
AWS App Mesh is a service mesh that provides application-level networking for microservices, enabling fine-grained control over service-to-service communication. It handles traffic management, provides visibility into service communications, and implements security controls like mTLS for secure service-to-service communication.
Q19An enterprise is migrating its on-premises applications to AWS and needs to maintain a hybrid architecture during the transition period. Which networking solution provides consistent connectivity with predictable performance?
✓ Correct answer: B. AWS Direct Connect
AWS Direct Connect provides a dedicated network connection from on-premises to AWS, offering more consistent network performance, reduced bandwidth costs, and increased throughput compared to internet-based connections. This makes it ideal for hybrid architectures requiring reliable, high-performance connectivity during migration.
Q20A healthcare company is migrating its application that processes sensitive patient data to AWS. The application currently uses a scheduling system to process batch jobs. Which serverless approach would modernize this component?
✓ Correct answer: A. AWS Step Functions with Lambda functions
AWS Step Functions allows you to coordinate multiple AWS services into serverless workflows. For healthcare batch processing involving sensitive data, Step Functions provides a visual workflow to orchestrate various services, maintain state, handle errors, and implement retry logic while complying with healthcare regulations.
