SAP-C02 Accelerate Workload Migration and Modernization Practice Test 9 — 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?

Accepted Answer

AWS Site-to-Site VPN. Option A is correct because AWS Site-to-Site VPN creates an encrypted connection between on-premises and VPC. Option B is wrong because VPC Peering does not extend on-premises network. Option C is wrong because AWS Transit Gateway connects VPCs and on-premises, but VPN is the actual mechanism to extend IPs. Option D is wrong because Direct Connect provides dedicated connection but does not inherently preserve IPs.

Answer

AWS Transit Gateway

Answer

VPC Peering

Answer

AWS Direct Connect

Question 2

A company is modernizing a legacy application by refactoring it into microservices. The application uses a monolithic Oracle database. The team wants to use Amazon RDS for Oracle as the migration target. Which migration approach minimizes risk and downtime?

Accepted Answer

Use the strangler fig pattern to incrementally migrate functionality to new microservices, each with its own database.. Option B is correct because the strangler fig pattern allows gradual migration. Option A is wrong because big bang migration is high risk. Option C is wrong because the phased approach may work but is broader; strangler fig is specific to microservices. Option D is wrong because rewriting all at once is high risk.

Answer

Create a new RDS instance and use AWS SCT to convert the schema, then cutover after testing.

Answer

Migrate the entire database at once using AWS DMS with ongoing replication.

Answer

Rewrite the application as microservices on AWS and then migrate the database.

Question 3

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 VM Import/Export. Option C is correct because AWS VM Import/Export allows importing VM images. Option A is wrong because AWS Server Migration Service (SMS) is now part of Application Migration Service. Option B is wrong because AWS DMS is for databases. Option D is wrong because AWS DataSync is for file data.

Answer

AWS DataSync

Answer

AWS Server Migration Service (SMS)

Answer

AWS Database Migration Service (DMS)

Question 4

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.. Option A is correct because 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 5

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.. Option C is correct because 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 6

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. Option D is correct because AWS Application Discovery Service collects server and application utilization data. Option A is wrong because AWS Migration Hub tracks migrations but does not discover. Option B is wrong because AWS Server Migration Service is deprecated. Option C is wrong because AWS DMS is for databases.

Answer

AWS Migration Hub

Answer

AWS Database Migration Service (DMS)

Answer

AWS Server Migration Service (SMS)

Question 7

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. Option A (AWS CloudFormation) and Option C (AWS CDK) are correct because both allow declarative infrastructure definition. Option B (AWS Elastic Beanstalk) is a PaaS service, not IaC. Option D (AWS OpsWorks) is configuration management. Option E (AWS CodeDeploy) is for deployment automation.

Answer

AWS Elastic Beanstalk

Answer

AWS OpsWorks

Answer

AWS CodeDeploy

Question 8

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). Option A (SQS), Option C (SNS), and Option D (EventBridge) are correct because they all enable asynchronous messaging and event-driven decoupling. Option B (Kinesis Data Streams) is for real-time streaming. Option E (Step Functions) is for orchestrating workflows, not primarily decoupling.

Answer

AWS Step Functions

Answer

Amazon Kinesis Data Streams

Question 9

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 A (use AWS DMS with ongoing replication) and Option D (use AWS SCT for schema conversion) are correct. Option B (take a full backup and restore) causes downtime. Option C (use Direct Connect for faster transfer) is helpful but not specifically for minimizing downtime. Option E (increase instance size) is not directly related.

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 10

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.. Option A is correct because 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 11

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.. Option C is correct because 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 12

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.. Option C is correct because the error explicitly states the instance does not have an attached root volume. Option A is wrong because the error mentions root volume, not a snapshot. Option B is wrong because the error does not mention permissions. Option D is wrong because the error does not mention format.

Answer

The specified S3 bucket is in a different region.

Answer

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

Answer

The instance is based on an instance store-backed AMI.

Question 13

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. Option A is correct because Amazon EFS provides a scalable, shared file system for Linux instances; for Windows, Amazon FSx for Windows File Server is the appropriate managed share. Option B (Amazon S3) is object storage and not a file system. Option C (Amazon EBS) is block storage and can be attached to only one instance. Option D (AWS Storage Gateway) is for hybrid storage, not native file sharing.

Answer

Amazon EBS

Answer

Amazon S3

Answer

AWS Storage Gateway

Question 14

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. Option C is correct because the strangler fig pattern allows incremental replacement of monolithic components with microservices, minimizing risk and enabling rollback. Option A (big bang) risks extended downtime. Option B (rehost) does not modernize. Option D (refactor) is correct but not a pattern name.

Answer

Refactor

Answer

Big bang migration

Answer

Rehost (lift and shift)

Question 15

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. Option D is correct because distribution style KEY on join columns ensures data is co-located, minimizing data movement. Option A (ALL) is not suitable for large tables. Option B (EVEN) distributes randomly. Option C (AUTO) may not use optimal distribution.

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
