SAP-C02 Accelerate Workload Migration and Modernization Practice Test 5 — 15 Questions

Question 1

A company is migrating its on-premises application to AWS and needs to maintain the same private IP addresses for the application servers. The on-premises network uses 10.0.0.0/16. Which AWS service allows the company to extend its on-premises network to AWS and preserve IP addresses?

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

Accepted Answer

AWS Site-to-Site VPN. AWS Site-to-Site VPN is correct because it establishes an IPsec tunnel between the on-premises network and the AWS VPC, allowing the on-premises 10.0.0.0/16 range to be routed into AWS without re-addressing. The VPC can use a non-overlapping CIDR, and the VPN connection plus route propagation lets application servers keep their existing private IPs while being reachable from on-premises. This directly extends the on-premises network into AWS.

Answer

AWS Transit Gateway

Answer

VPC Peering

Answer

AWS Direct Connect

Question 2

A company is planning to migrate its on-premises Oracle database to Amazon RDS for Oracle. Which actions should the company take to minimize downtime during the migration? (Choose TWO.)

Accepted Answer

Use AWS Schema Conversion Tool (SCT) to convert the schema and optimize for RDS.. Option D is correct because AWS Schema Conversion Tool (SCT) converts the source Oracle schema and objects into a format compatible with Amazon RDS for Oracle, resolving incompatibilities and optimizing the schema before the cutover so the actual data migration window is shorter and downtime is minimized. Option E is correct because AWS Database Migration Service (DMS) with ongoing (change data capture) replication continuously applies changes from the on-premises Oracle database to the RDS target, allowing a near-zero-downtime cutover once the target is in sync. Option A is not ideal because a full backup and restore during a maintenance window is a one-time, offline operation that does not keep the target synchronized and typically requires significant downtime. Option B is not correct because AWS Direct Connect improves network throughput and consistency but does not by itself minimize migration downtime. Option C is not correct because increasing RDS storage does not address the synchronization or cutover process needed to reduce downtime.

Answer

Take a full backup of the on-premises database and restore it to RDS during a maintenance window.

Answer

Use AWS Direct Connect to establish a dedicated network connection for faster data transfer.

Answer

Increase the allocated storage on the target RDS instance to improve write performance.

Question 3

An administrator attempts to start an EC2 instance that was previously stopped. The instance fails to start. The administrator runs the CLI command shown in the exhibit. What is the most likely cause of the failure?

Accepted Answer

The instance is in the 'stopped' state and needs to be started.. The exhibit shows the CLI output for an EC2 instance whose state is 'stopped'. A stopped instance does not run and must be explicitly started with 'aws ec2 start-instances' (or the console Start action). The failure to start is therefore simply because the instance is in the stopped state and no start command was issued, or the start command targeted the wrong state.

Answer

The instance ID is incorrect.

Answer

The instance is in 'pending' state and will start automatically.

Answer

The instance has been terminated.

Question 4

A solutions architect is trying to export an EC2 instance as a VM using AWS VM Import/Export. The CLI command fails with the error shown in the exhibit. What is the most likely cause?

Accepted Answer

The instance is not an EBS-backed instance.. AWS VM Import/Export only supports exporting EBS-backed EC2 instances; instance store-backed AMIs cannot be exported. The error in the exhibit (typical VM Import/Export failure) indicates the instance is either not EBS-backed or is based on an instance store-backed AMI, both of which are unsupported for export. Options B and D describe the same underlying limitation from different angles.

Answer

The specified S3 bucket is in a different region.

Answer

The IAM role used does not have permission to export instances.

Question 5

A company is migrating a legacy Windows application to AWS. The application requires a shared file system accessible from multiple EC2 instances in the same VPC. Which AWS service should the company use to meet this requirement with minimal application changes?

Accepted Answer

Amazon FSx for Windows File Server. Mazon FSx for Windows File Server (option C). This service provides a fully managed native Windows file system that is accessible from multiple EC2 instances in the same VPC, supporting the SMB protocol required by Windows applications. Option A (Amazon EBS) is block storage that can be attached to only one instance at a time, not a shared file system. Option B (Amazon S3) is object storage and does not provide a file system interface. Option D (AWS Storage Gateway) is used for hybrid cloud storage and is not the optimal choice for this scenario.

Answer

Amazon EBS

Answer

Amazon S3

Answer

AWS Storage Gateway

Question 6

A company wants to migrate its on-premises Oracle database to Amazon RDS for MySQL with minimal downtime. Which AWS service should be used for the initial data load and ongoing replication?

Accepted Answer

AWS Database Migration Service (DMS). AWS Database Migration Service (DMS) is designed for migrating databases to AWS with minimal downtime. It supports both initial full load and ongoing replication (change data capture) from Oracle to RDS for MySQL, handling schema conversion and data type mappings. DMS continuously replicates changes, ensuring the target stays in sync until cutover.

Answer

AWS Schema Conversion Tool (SCT)

Answer

Amazon S3

Answer

AWS Direct Connect

Question 7

A company is migrating a stateful application to AWS. The application uses local storage for temporary data that must survive instance restarts but not region failures. Which storage solution should the company use?

Accepted Answer

Instance Store. Instance Store provides ephemeral block storage physically attached to the host, and its data survives instance reboots (restarts) but is lost on instance stop/terminate or host failure. That matches the requirement: data must survive restarts but not region failures, and it is local storage for temporary data.

Answer

Amazon EBS

Answer

Amazon S3

Answer

Amazon EFS

Question 8

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 9

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. A warm standby strategy maintains a scaled-down but fully functional copy of the application in a second Region, with data replicated continuously. It can be scaled up to full production capacity within minutes, meeting a 15-minute RTO, while continuous replication (e.g., asynchronous database replication) supports an RPO of about 1 minute. This balances cost and recovery speed better than pilot light or backup/restore.

Answer

Multi-Region active-active deployment with synchronous replication

Answer

Pilot light in another Region

Answer

Backup and restore to another Region

Question 10

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. The AWS SMS connector (A) is required because it is the on-premises virtual appliance that must be installed on the source hypervisor (VMware vSphere, Hyper-V, or Azure) to inventory VMs and replicate their volumes to AWS as AMIs. AWS Migration Hub (C) is required to provide a single location to track the migration status of servers across SMS and other migration tools, satisfying the tracking requirement. AWS CloudFormation (E) is required to automate the creation of the target infrastructure and launch migrated servers from SMS-generated AMIs, fulfilling the automation requirement. The AWS Schema Conversion Tool (B) and AWS Database Migration Service (D) are database-focused services used for heterogeneous and homogeneous database migrations respectively, which are not part of an SMS server replication workflow.

Answer

AWS Schema Conversion Tool

Answer

AWS Database Migration Service

Question 11

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 DMS with ongoing replication continuously replicates the on-premises MySQL database to Amazon RDS for MySQL in the same VPC, so the application can cut over to a local RDS endpoint with minimal code change (only the JDBC connection string). This eliminates the high-latency cross-Direct-Connect database calls that are causing the performance problem, while keeping the database in sync during the migration testing phase.

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 12

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.. Rehosting (lift-and-shift) on EC2 with RDS for MySQL is the correct strategy because it moves the existing single-server application to AWS with minimal changes while offloading database management to RDS. This minimizes operational overhead compared to managing MySQL on EC2 and preserves application compatibility, satisfying the requirement without a costly rewrite. It also enables vertical/horizontal scaling of the EC2 tier and Multi-AZ/read replicas on RDS.

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 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 legacy mainframe application to AWS. The application uses a hierarchical database (IMS) and has complex batch processing jobs. The company wants to minimize changes to the application code. Which approach should be taken?

Accepted Answer

Rehost the application on AWS Mainframe Modernization using Blu Age. AWS Mainframe Modernization with Blu Age is a rehost/replatform pattern that automates conversion of legacy mainframe applications (including COBOL, IMS, and batch jobs) to run on AWS with minimal code changes. It preserves the hierarchical IMS database semantics and batch processing model, which directly matches the requirement to minimize application changes. This is the purpose-built service for mainframe migration.

Answer

Replace the application with a SaaS-based ERP system

Answer

Re-platform the database to Amazon RDS for PostgreSQL

Answer

Refactor the application to use microservices on Amazon EKS

Question 15

A company is modernizing its monolithic Java application to a microservices architecture on AWS. The application uses a shared Oracle database. The team wants to implement an event-driven architecture. Which TWO AWS services should be used to decouple microservices and handle asynchronous communication?

Accepted Answer

Amazon EventBridge. Amazon EventBridge (D) is correct because it is a serverless event bus that routes events between microservices using rules and event patterns, enabling loosely coupled, event-driven communication across services and SaaS applications. Amazon SQS (E) is correct because it provides fully managed message queues that decouple producers from consumers, buffering messages and enabling reliable asynchronous point-to-point communication between microservices. Together they support the event-driven architecture the team needs: EventBridge for event routing and SQS for durable asynchronous message handling. AWS AppSync (A) is a managed GraphQL service for APIs and real-time data sync, not an event bus or queue for microservice decoupling. Amazon Kinesis Data Streams (C) is designed for real-time streaming ingestion and analytics of high-volume data, not for general microservice decoupling and asynchronous messaging. Amazon SNS (B) is a pub/sub notification service, but the question asks for the two services that best decouple microservices and handle asynchronous communication, which are EventBridge and SQS.

Answer

AWS AppSync

Answer

Amazon Simple Notification Service (SNS)

Answer

Amazon Kinesis Data Streams
