SAP-C02 Accelerate Workload Migration and Modernization Practice Test 11 — 15 Questions

Question 1

A company is modernizing a legacy application by breaking it into microservices. The application uses a shared MySQL database. The team wants to refactor the database to use Amazon DynamoDB for better scalability. Which migration strategy should be used?

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

Accepted Answer

Use the Strangler Fig pattern to incrementally migrate data to DynamoDB. The Strangler Fig pattern is the correct migration strategy because it allows for incremental and iterative migration of data and business logic from the legacy MySQL database to Amazon DynamoDB without a full cutover. This approach minimizes risk and enables the team to gradually refactor the application while maintaining continuous operation. Option A (rehost to Amazon RDS) would still use a relational database and not achieve the goal of moving to DynamoDB. Option C (replatform to Amazon Aurora) also retains a relational model. Option D (retire the existing database and switch to DynamoDB) is risky as it requires a complete cutover without incremental transition.

Answer

Rehost the database to Amazon RDS

Answer

Replatform the database to Amazon Aurora

Answer

Retire the existing database and switch to DynamoDB

Question 2

A company wants to automate the migration of on-premises servers to AWS. The migration plan includes discovery, assessment, and automated replication. Which AWS service should the company use?

Accepted Answer

AWS Migration Hub. (AWS Migration Hub) is correct because it provides a centralized location to track the progress of migrations across multiple AWS and partner tools, including discovery, assessment, and replication. It integrates with AWS Application Discovery Service for discovery and assessment, and with AWS Server Migration Service (SMS) or AWS Application Migration Service (MGN) for automated replication. Option A (AWS CloudEndure Migration) is now part of AWS Application Migration Service (MGN) and focuses on replication, not end-to-end tracking. Option C (AWS Schema Conversion Tool) is used for converting database schemas, not for server migration. Option D (AWS Database Migration Service) is specifically for database migrations, not for general server migration management.

Answer

AWS CloudEndure Migration

Answer

AWS Schema Conversion Tool

Answer

AWS Database Migration Service

Question 3

A company is migrating a critical application to AWS and needs to ensure business continuity. The application must be able to fail over to a different AWS Region with a Recovery Time Objective (RTO) of 15 minutes and a Recovery Point Objective (RPO) of 1 minute. Which strategy should the company use?

Accepted Answer

Warm standby in another Region. Warm standby in another Region is the best strategy to achieve RTO of 15 minutes and RPO of 1 minute. A warm standby involves running a scaled-down version of the production environment in another Region, which can be quickly scaled up during failover. This approach allows for continuous data replication, typically with asynchronous replication that can achieve an RPO of 1 minute, and failover within minutes, meeting the 15-minute RTO. Multi-Region active-active with synchronous replication is often impractical across long distances due to latency and cost, and synchronous replication typically requires both Regions to be active, which is complex and not necessary for this requirement. Pilot light has longer RTO (typically 10-30 minutes or more) and backup and restore has much higher RTO and RPO.

Answer

Multi-Region active-active deployment with synchronous replication

Answer

Pilot light in another Region

Answer

Backup and restore to another Region

Question 4

A company is migrating a large Hadoop cluster to Amazon EMR. The cluster uses HDFS for storage. The company wants to decouple compute and storage to reduce costs. Which approach should the company take?

Accepted Answer

Use Amazon S3 as the data store and EMRFS. The correct approach is Option A: Use Amazon S3 as the data store with EMRFS (EMR File System). This decouples compute and storage because Amazon EMR clusters can read/write data directly to S3, allowing the cluster to be terminated when not needed while data persists in S3. Option B (FSx for Lustre) is a high-performance file system but still ties compute to storage. Option C (EFS) is not optimized for Hadoop workloads. Option D (EBS volumes) are attached to the EC2 instances, coupling compute and storage.

Answer

Use Amazon FSx for Lustre

Answer

Use Amazon EFS for HDFS

Answer

Use EBS volumes for HDFS

Question 5

A company is migrating a legacy application to AWS. The application requires a relational database. The company wants to minimize operational overhead. Which TWO options should the company consider? (Choose two.)

Accepted Answer

Amazon Aurora. Amazon Aurora (option B) and Amazon RDS (option D) are both fully managed relational database services that minimize operational overhead. AWS Database Migration Service (option A) is a migration tool, not a database service. Amazon S3 (option C) is object storage, not a relational database. Amazon EC2 with self-managed database (option E) requires manual administration, increasing overhead.

Answer

AWS Database Migration Service

Answer

Amazon S3

Answer

Amazon EC2 with self-managed database

Question 6

A company is performing a server migration to AWS using AWS Server Migration Service (SMS). The company needs to automate the replication of servers and track the migration status. Which THREE components are required for this solution? (Choose three.)

Accepted Answer

AWS SMS connector installed on the on-premises hypervisor. Options A, C, and E are correct. AWS SMS connector is installed on-premises to enable server replication. AWS Migration Hub provides a central location to track the migration status of servers. AWS CloudFormation can be used to automate the deployment of resources and manage the migration pipeline. Option B (AWS Schema Conversion Tool) is for schema conversion of databases, not server migration. Option D (AWS Database Migration Service) is specifically for database migrations, not server replication.

Answer

AWS Schema Conversion Tool

Answer

AWS Database Migration Service

Question 7

A company wants to migrate a legacy .NET application to AWS. The application uses Windows authentication and requires a shared file system. Which TWO AWS services should the company use to modernize this application? (Choose two.)

Accepted Answer

Amazon FSx for Windows File Server. Options A and B are correct. Amazon FSx for Windows File Server (A) provides a native Windows file system with SMB support, ideal for shared file storage in .NET applications that require Windows authentication. AWS Elastic Beanstalk (B) offers a managed environment for .NET applications, simplifying deployment and scaling. Option C (Amazon S3) is object storage, not a shared file system. Option D (Amazon EBS) is block storage and cannot be shared across multiple instances. Option E (AWS Lambda) does not support .NET Framework natively and is not suitable for this use case.

Answer

Amazon S3

Answer

Amazon EBS

Answer

AWS Lambda

Question 8

A company is migrating a legacy on-premises application to AWS. The application consists of a web server, an application server, and a MySQL database. The company has already migrated the web and application servers to EC2 instances in a VPC. The database is still on-premises. The application currently connects to the database using a JDBC connection string with the on-premises IP address. The company wants to minimize changes to the application code. The network team has established an AWS Direct Connect connection between the on-premises data center and the VPC. The security team requires that traffic between the application and the database be encrypted in transit. The database is not publicly accessible. The migration plan includes moving the database to Amazon RDS for MySQL in the same VPC after the initial cutover. During the migration testing phase, the application team reports that the application can connect to the on-premises database but performance is slower than expected. CloudWatch metrics show high latency on the database connections. The application uses a connection pool with 100 connections. Which solution should the solutions architect recommend to improve performance while minimizing application code changes?

Accepted Answer

Use AWS Database Migration Service to set up ongoing replication from on-premises to RDS. AWS Database Migration Service (DMS) with ongoing replication can continuously replicate data from the on-premises MySQL database to an Amazon RDS for MySQL instance in the same VPC. This allows the application to connect to the local RDS instance, significantly reducing latency compared to the Direct Connect link. To minimize code changes, the application's JDBC connection string can be updated to point to the RDS endpoint, or a DNS CNAME can be used to abstract the change. Option A (increasing connection pool size) does not reduce network latency and may worsen performance. Option B (read replica) is not feasible because an RDS read replica can only replicate from an RDS primary, not from an on-premises database. Option D (Multi-AZ) is not applicable until the database is on AWS and does not improve latency.

Answer

Increase the connection pool size to 200 and enable connection multiplexing

Answer

Deploy an Amazon RDS for MySQL read replica in the same Region and direct read traffic to it

Answer

Enable Multi-AZ on the RDS instance

Question 9

A retail company is migrating its on-premises e-commerce application to AWS. The application currently runs on a single server with a MySQL database. The company wants to minimize operational overhead and improve scalability. Which migration strategy should be used?

Accepted Answer

Rehost the application on Amazon EC2 and use Amazon RDS for MySQL.. (Rehost) is the best migration strategy for this scenario because it involves lifting and shifting the application to Amazon EC2 with minimal changes, and using Amazon RDS for MySQL reduces operational overhead for database management. Rehosting is the fastest approach and aligns with the goal of minimizing operational overhead while improving scalability through managed services. Option A (Re-platform) would require modifications to use Elastic Beanstalk, increasing effort. Option B (Repurchase) involves switching to a new SaaS solution, which is not a migration of the existing application. Option C (Refactor) requires significant development to convert to microservices, which is high effort and not necessary for the stated goals.

Answer

Re-platform the application to use AWS Elastic Beanstalk and Amazon RDS.

Answer

Repurchase a new SaaS-based e-commerce solution.

Answer

Refactor the application as microservices on Amazon ECS with Amazon Aurora Serverless.

Question 10

A company is planning to migrate its on-premises data warehouse to AWS. The data warehouse runs on a large Oracle RAC cluster with complex stored procedures and ETL jobs. The company wants to minimize migration effort while gaining cloud benefits. Which AWS service should be used as the target?

Accepted Answer

Amazon Redshift. Amazon Redshift is the AWS data warehouse service that can migrate from Oracle RAC with minimal changes using the AWS Schema Conversion Tool (SCT). Option A is incorrect because Amazon DynamoDB is a NoSQL database, not a data warehouse. Option B is incorrect because Amazon RDS for Oracle is a relational database service and not optimized for data warehousing workloads. Option D is incorrect because Amazon Aurora PostgreSQL is a relational database, not a data warehouse.

Answer

Amazon DynamoDB

Answer

Amazon RDS for Oracle

Answer

Amazon Aurora PostgreSQL

Question 11

A company is migrating a legacy .NET application to AWS. The application uses Windows authentication and has a dependency on a local file system. The company wants to minimize code changes. Which combination of services should be used?

Accepted Answer

Amazon EC2 Windows instances with Amazon FSx for Windows File Server. Amazon EC2 Windows instances provide a native Windows environment, and Amazon FSx for Windows File Server offers fully managed Windows file shares that support SMB protocol, Windows authentication, and NTFS file system. This combination minimizes code changes by preserving the existing Windows authentication and local file system dependencies. Option A is incorrect because Amazon EFS uses NFS and does not natively support Windows SMB. Option B is incorrect because AWS Elastic Beanstalk for Windows may complicate Windows authentication and lacks the flexibility for direct file system access. Option C is incorrect because Amazon Lightsail with local instance storage does not provide shared file storage and may not scale as needed.

Answer

Amazon EC2 Windows instances with Amazon EFS

Answer

AWS Elastic Beanstalk with Amazon EFS

Answer

Amazon Lightsail with local instance storage

Question 12

A company is migrating a critical application to AWS and needs to ensure business continuity during the migration. The application must remain available with minimal downtime. Which AWS service should be used to replicate data continuously?

Accepted Answer

AWS Database Migration Service (DMS) with ongoing replication. AWS Database Migration Service (DMS) with ongoing replication can keep source and target databases in sync, allowing for minimal downtime during migration. Option A is wrong because AWS Direct Connect provides a dedicated network connection, not a replication service. Option C is wrong because Amazon S3 Transfer Acceleration is for faster uploads to S3, not for database replication. Option D is wrong because AWS Snowball Edge is an offline data transfer device, not a continuous replication tool.

Answer

AWS Direct Connect

Answer

Amazon S3 Transfer Acceleration

Answer

AWS Snowball Edge

Question 13

A company is modernizing its monolithic application by breaking it into microservices. The application uses a shared MySQL database. The team wants to implement a database per microservice pattern. Which AWS service should be used to manage multiple databases efficiently?

Accepted Answer

Amazon RDS for MySQL with multiple DB instances. Amazon RDS for MySQL can manage multiple DB instances, each dedicated to a microservice, with managed backups, scaling, and maintenance. Option B (Amazon ElastiCache for Redis) is wrong because it is a caching layer, not a primary database. Option C (Amazon DynamoDB) is wrong because it is a NoSQL database, which may not suit all microservices, especially those requiring relational data. Option D (Amazon EFS) is wrong because it is a file storage service, not a database.

Answer

Amazon ElastiCache for Redis

Answer

Amazon DynamoDB

Answer

Amazon EFS

Question 14

A company is migrating a large-scale on-premises Apache Kafka cluster to AWS. The cluster handles real-time streaming data from thousands of IoT devices. The company wants to reduce operational overhead and ensure high availability. Which AWS service should be used?

Accepted Answer

Amazon Managed Streaming for Apache Kafka (MSK). (Amazon MSK) is correct because Amazon MSK is a fully managed Apache Kafka service that reduces operational overhead and supports high availability. Option B (SNS) is wrong because Amazon SNS is a pub/sub messaging service, not a streaming platform compatible with Apache Kafka. Option C (SQS) is wrong because Amazon SQS is a queue service, not a streaming platform. Option D (Kinesis Data Streams) is wrong because while it is a streaming service, it uses its own API and is not compatible with Apache Kafka, requiring significant re-architecture.

Answer

Amazon Simple Notification Service (SNS)

Answer

Amazon Simple Queue Service (SQS)

Answer

Amazon Kinesis Data Streams
