SAP-C02 Accelerate Workload Migration and Modernization Practice Test 10 — 15 Questions

Question 1

A company plans to migrate its on-premises VMware VMs to AWS. The company wants to automate the migration of VM images and minimize manual effort. Which AWS service should the company use?

Accepted Answer

AWS Application Migration Service (MGN). AWS Application Migration Service (MGN) is the correct choice because it automates the migration of on-premises server volumes (including VMware VMs) to AWS with minimal manual effort. It provides continuous, block-level replication and simplifies large-scale migrations. MGN is the modern successor to AWS Server Migration Service (SMS). AWS VM Import/Export (Option A) is a one-time import tool requiring manual steps. AWS DataSync (Option B) is for file and object transfers, not VM images. AWS DMS (Option D) is for databases. Therefore, MGN (Option C) is the service that best meets the requirement.

Answer

AWS VM Import/Export

Answer

AWS DataSync

Answer

AWS Database Migration Service (DMS)

Question 2

A company is migrating a critical application to AWS and needs to ensure high availability across two Availability Zones. The application runs on EC2 instances behind an Application Load Balancer (ALB). The database is an on-premises SQL Server that will be migrated later. Which architecture provides high availability for the application tier during the migration?

Accepted Answer

Deploy EC2 instances in two AZs behind an ALB with cross-zone load balancing enabled.. ALB distributes traffic to instances in two AZs. Option B is wrong because a single AZ is not highly available. Option C is wrong because a Network Load Balancer is for TCP/UDP, not HTTP. Option D is wrong because Route 53 alone does not provide load balancing.

Answer

Deploy EC2 instances in a single AZ with an Auto Scaling group.

Answer

Deploy EC2 instances in two AZs behind a Network Load Balancer (NLB).

Answer

Use Amazon Route 53 weighted routing to distribute traffic to instances in two AZs.

Question 3

A company is migrating a legacy .NET application to AWS. The application uses Windows authentication and connects to an on-premises SQL Server database. The company wants to minimize code changes. Which migration strategy is most appropriate?

Accepted Answer

Rehost the application on EC2 Windows instances and use Amazon RDS for SQL Server.. Rehosting on EC2 Windows with RDS SQL Server minimizes changes and supports Windows authentication. Option A is wrong because re-platforming to Linux may break .NET dependencies. Option B is wrong because refactoring to serverless requires significant code changes. Option D is wrong because moving to Aurora PostgreSQL requires code changes.

Answer

Replatform the application to use Amazon Aurora PostgreSQL with AWS DMS.

Answer

Refactor the application into microservices using AWS Lambda and Amazon DynamoDB.

Answer

Re-platform the application to run on Amazon Linux and use Amazon RDS for MySQL.

Question 4

A company wants to assess its on-premises environment for migration to AWS. The company needs to collect utilization data for servers and applications. Which AWS service should the company use?

Accepted Answer

AWS Application Discovery Service. AWS Application Discovery Service collects server and application utilization data from on-premises environments to support migration planning. Option A is wrong because AWS Migration Hub tracks migrations but does not perform discovery. Option B is wrong because AWS Database Migration Service (DMS) is for migrating databases, not for collecting utilization data. Option D is wrong because AWS Server Migration Service (SMS) is deprecated and was used for migrating individual servers, not for discovery.

Answer

AWS Migration Hub

Answer

AWS Database Migration Service (DMS)

Answer

AWS Server Migration Service (SMS)

Question 5

A company is migrating a multi-tier web application to AWS and wants to use Infrastructure as Code (IaC) to automate provisioning. Which AWS services can the company use to define and manage infrastructure declaratively? (Choose TWO.)

Accepted Answer

AWS CloudFormation. AWS CloudFormation and AWS CDK are correct because both allow declarative infrastructure definition. AWS Elastic Beanstalk is a PaaS service, not dedicated Infrastructure as Code. AWS OpsWorks is configuration management. AWS CodeDeploy is for deployment automation.

Answer

AWS Elastic Beanstalk

Answer

AWS OpsWorks

Answer

AWS CodeDeploy

Question 6

A company is migrating a legacy application to AWS and needs to decouple the application components. The application currently uses a monolithic architecture with direct calls between components. Which AWS services can help decouple the components? (Choose THREE.)

Accepted Answer

Amazon Simple Queue Service (SQS). Amazon SQS (Option A), Amazon SNS (Option B), and Amazon EventBridge (Option E) are correct because they all enable asynchronous messaging and event-driven decoupling between application components. SQS provides message queues for decoupling producers and consumers, SNS supports pub/sub messaging, and EventBridge routes events from various sources. AWS Step Functions (Option C) is designed for orchestrating workflows, not primarily for decoupling. Amazon Kinesis Data Streams (Option D) is used for real-time streaming analytics, not general decoupling.

Answer

AWS Step Functions

Answer

Amazon Kinesis Data Streams

Question 7

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.. Options D and E are correct. AWS Schema Conversion Tool (SCT) converts the schema to be compatible with Amazon RDS for Oracle, reducing compatibility issues. AWS Database Migration Service (DMS) with ongoing replication allows continuous sync from the source to target, minimizing downtime during migration. Option A (full backup and restore) requires downtime during the restore. Option B (Direct Connect) improves transfer speed but does not directly minimize downtime; it's a network enhancement. Option C (increased storage) improves write performance but does not minimize migration 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 8

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 instance is in 'stopped' state (Code 80), not 'running'. Option B is wrong because the state is stopped, not pending. Option C is wrong because there is no error in the output. Option D is wrong because the output shows the instance exists.

Answer

The instance ID is incorrect.

Answer

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

Answer

The instance has been terminated.

Question 9

A company attaches the IAM policy shown in the exhibit to an IAM user. The user tries to upload an object to my-bucket using the AWS CLI without the --ssl flag (i.e., using HTTP). What will happen?

Accepted Answer

The upload fails with an explicit deny because of the Deny statement.. The Deny statement with aws:SecureTransport=false explicitly denies non-HTTPS requests. Option A is wrong because the Allow statement requires HTTPS. Option B is wrong because the Deny is explicit. Option D is wrong because the Deny is explicit.

Answer

The upload fails with an implicit denial because the Allow condition is not met.

Answer

The upload succeeds because the Allow statement grants s3:PutObject.

Answer

The upload succeeds because there is no explicit Deny for s3:PutObject.

Question 10

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.. The error message indicates that the instance does not have an attached root volume, which is characteristic of an instance store-backed instance. AWS VM Import/Export only supports EBS-backed instances. Since an instance store-backed AMI means the instance is not EBS-backed, both options B (the instance is not an EBS-backed instance) and D (the instance is based on an instance store-backed AMI) accurately describe the cause. Option A is incorrect because a region mismatch would produce a different error. Option C is incorrect because the error does not mention permissions.

Answer

The specified S3 bucket is in a different region.

Answer

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

Question 11

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 12

A company is migrating a monolithic e-commerce application to a microservices architecture on AWS. The migration must minimize downtime and allow rollback. Which migration strategy should the company use?

Accepted Answer

Strangler fig pattern. The strangler fig pattern allows gradual replacement of monolithic components with microservices, minimizing downtime and enabling easy rollback. Option A (refactor) typically involves rewriting the entire application, which often requires significant downtime and increases risk. Option B (big bang migration) migrates all components at once, leading to extended downtime and high risk. Option D (rehost) moves the monolith as-is without modernization, which does not achieve the goal of migrating to a microservices architecture.

Answer

Refactor

Answer

Big bang migration

Answer

Rehost (lift and shift)

Question 13

A company is migrating a data warehouse from on-premises to Amazon Redshift. The current workload runs complex queries that join large tables. The company wants to optimize query performance after migration. Which design should the company implement?

Accepted Answer

Use distribution style KEY on the join columns of large tables. Distribution style KEY on join columns ensures data is co-located, minimizing data movement. Option A (AUTO) may not use the optimal distribution strategy. Option B (EVEN) distributes rows evenly, which can cause significant data movement across nodes. Option C (ALL) is not suitable for large tables because it duplicates the entire table on every node, leading to high storage and performance issues.

Answer

Use distribution style AUTO and let Redshift decide

Answer

Use distribution style EVEN on all tables

Answer

Use distribution style ALL on all large tables

Question 14

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) supports both initial data load and ongoing replication from on-premises Oracle to Amazon RDS for MySQL with minimal downtime. Option A (AWS SCT) is used for schema conversion, not data migration. Option B (Amazon S3) is a storage service, not a migration service. Option C (AWS Direct Connect) provides network connectivity but does not perform data migration.

Answer

AWS Schema Conversion Tool (SCT)

Answer

Amazon S3

Answer

AWS Direct Connect

Question 15

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 that persists across instance reboots but is lost if the instance is stopped or terminated. This matches the requirement for temporary data that survives restarts but not region failures. Option A (Amazon EBS) survives stops, which is unnecessary. Option C (Amazon S3) is object storage, not temporary local storage. Option D (Amazon EFS) is a network file system, not local storage.

Answer

Amazon EBS

Answer

Amazon S3

Answer

Amazon EFS
