SAP-C02 Practice Test 32 — 15 Questions

Question 1

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 2

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. Correct answers are D (Amazon EventBridge) and E (Amazon Simple Queue Service - SQS). SQS provides a reliable message queue for decoupling microservices and enabling asynchronous communication. EventBridge allows building event-driven architectures by routing events from various sources to targets. Option A (AWS AppSync) is for building GraphQL APIs; it does not handle decoupling in an event-driven pattern. Option B (Amazon SNS) is a pub/sub notification service but not primarily for decoupling queues; it can be used for fan-out but not as a queue. Option C (Amazon Kinesis Data Streams) is for real-time streaming data; it is not typically used for simple decoupling of microservices.

Answer

AWS AppSync

Answer

Amazon Simple Notification Service (SNS)

Answer

Amazon Kinesis Data Streams

Question 3

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 4

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 5

A company is migrating a critical application to AWS and must ensure business continuity with a Recovery Time Objective (RTO) of 1 hour and a Recovery Point Objective (RPO) of 15 minutes. The application runs on a single on-premises server with a 500 GB disk. The current data changes at a rate of 10 MB per minute. Which solution will meet the RTO and RPO requirements with the least operational overhead?

Accepted Answer

Use AWS Application Migration Service (AWS MGN) to replicate the server continuously and automate cutover.. AWS Application Migration Service (AWS MGN) continuously replicates data with near-zero RPO and supports automated testing and cutover. It can achieve an RTO of less than 1 hour for a single server. AWS DMS is for database migration, not full server. AWS Backup has a minimum RPO of 1 hour for continuous backups. Manual snapshots cannot achieve 15-minute RPO due to the rate of change and manual intervention.

Answer

Use AWS Database Migration Service (AWS DMS) to replicate the database continuously.

Answer

Use AWS DataSync to replicate the server every 15 minutes to an EBS volume.

Answer

Take hourly snapshots of the server using AWS Backup and restore in a new EC2 instance.

Question 6

A company is migrating an on-premises .NET application to AWS. The application uses a SQL Server database with a large number of stored procedures and triggers. The company wants to reduce licensing costs by moving to an open-source database. Which AWS service should the solutions architect use to automate the database conversion?

Accepted Answer

AWS Schema Conversion Tool (SCT). AWS Schema Conversion Tool (SCT) automates the conversion of database schema and code to a target database like PostgreSQL or MySQL. DMS handles data migration, not schema conversion. App2Container is for containerizing applications. CloudEndure is for server migration.

Answer

AWS Database Migration Service (DMS)

Answer

AWS App2Container

Answer

AWS Application Migration Service (CloudEndure)

Question 7

A company is modernizing a .NET Framework application to run on AWS. The application currently uses Windows Communication Foundation (WCF) services. The company wants to minimize code changes and run on Linux. Which approach should the company take?

Accepted Answer

Port the application to .NET Core and deploy on Amazon ECS with Linux containers.. Migrating the .NET Framework application to .NET Core allows it to run on Linux with minimal code changes, as .NET Core is cross-platform. Deploying on Amazon ECS with Linux containers meets the requirement to run on Linux. Option A is incorrect because using AWS App2Container to generate Windows containers would still require Windows, not Linux. Option B is incorrect because rewriting WCF services as AWS Lambda functions would require significant refactoring, not minimal code changes. Option D is incorrect because AWS Fargate is a compute platform, not a framework, and running Windows containers does not satisfy the requirement to run on Linux.

Answer

Use AWS App2Container to generate Windows containers and run on Amazon ECS with Windows.

Answer

Rewrite the WCF services as AWS Lambda functions using a custom runtime.

Answer

Containerize the application using AWS Fargate and run on Windows containers.

Question 8

A company is migrating a data warehouse from on-premises to Amazon Redshift. The source database is Teradata. The company needs to convert the schema and migrate historical data with minimal downtime. Which THREE services should the company use?

Accepted Answer

AWS Snowball Edge. Options A, D, and E are correct. AWS SCT (D) converts schema and code from Teradata to Redshift. AWS DMS (E) migrates data with ongoing replication to minimize downtime. AWS Snowball Edge (A) can be used for large initial data transfer. Option B (AWS Data Pipeline) is for orchestrating data transfers, not specifically for schema conversion or database migration. Option C (Amazon Kinesis Data Analytics) is for streaming analytics.

Answer

AWS Data Pipeline

Answer

Amazon Kinesis Data Analytics

Question 9

A company is migrating a stateful web application to AWS. The application currently runs on a single on-premises server and uses local storage for session data. The company wants to make the application highly available and scalable. What should the solutions architect do?

Accepted Answer

Migrate session data to Amazon ElastiCache or DynamoDB, then use an Auto Scaling group behind an ALB. Moving session state to ElastiCache or DynamoDB makes the application stateless, enabling Auto Scaling. Sticky sessions on an ALB are a workaround but do not provide full statelessness. Using a larger instance does not provide high availability. Multi-AZ RDS for session data is not ideal for high-frequency session access.

Answer

Store session data in a Multi-AZ Amazon RDS database and use Route 53 with health checks

Answer

Use an Application Load Balancer with sticky sessions and an Auto Scaling group

Answer

Use a larger EC2 instance to handle all traffic and take regular snapshots

Question 10

A company is migrating an on-premises Hadoop cluster to Amazon EMR. The cluster processes large datasets that are stored on HDFS. The company wants to minimize migration effort and cost. Which storage option should the company use with Amazon EMR?

Accepted Answer

Amazon S3 with EMRFS. Amazon S3 with EMRFS allows EMR to use S3 as a scalable, durable, and cost-effective storage layer, eliminating the need to manage HDFS. Option A is incorrect because EBS volumes require provisioning and management, and do not provide the same scalability and cost benefits. Option C is incorrect because Amazon FSx for HDFS is suitable for workloads requiring HDFS compatibility but is more complex and expensive than using S3. Option D is incorrect because Amazon EFS is a file system, not optimized for Hadoop workloads and typically used for shared file storage.

Answer

Amazon EBS volumes attached to the core nodes

Answer

Amazon FSx for HDFS

Answer

Amazon Elastic File System (EFS)

Question 11

A company is migrating a legacy application that uses a proprietary binary protocol for communication. The application communicates over TCP/IP. The company wants to modernize the communication layer to use a RESTful API. Which TWO approaches should the company consider?

Accepted Answer

Use Amazon API Gateway and AWS Lambda to create a REST API that translates requests to the legacy protocol.. Options B and D are correct. Option B: Using Amazon API Gateway and AWS Lambda allows the company to create a REST API that acts as a facade, translating RESTful calls into the legacy binary protocol, enabling gradual modernization without full application rewrite. Option D: Refactoring the application to communicate directly over HTTP and using Amazon API Gateway provides a modern, fully managed RESTful interface, which is the ideal long-term solution. Option A (Amazon MQ) is a message broker and not designed for protocol translation to REST. Option C (AWS App Mesh) is a service mesh for observability and traffic control, not for protocol conversion. Option E (Amazon CloudFront) is a CDN and cannot translate protocols.

Answer

Replace the binary protocol with Amazon MQ.

Answer

Use AWS App Mesh to convert the binary protocol to HTTP.

Answer

Use Amazon CloudFront to cache the RESTful endpoints.

Question 12

A company is migrating a legacy application to AWS using the rehost (lift-and-shift) strategy. The application uses a proprietary database that is not supported by Amazon RDS. The company wants to automate the migration of multiple servers and minimize downtime. Which AWS service should be used to automate the server migration?

Accepted Answer

AWS Application Migration Service (AWS MGN).. AWS Application Migration Service (MGN) automates lift-and-shift with minimal downtime. Option A is wrong because AWS CloudFormation is for infrastructure provisioning, not migration. Option C is wrong because AWS Server Migration Service (SMS) is older and less automated compared to MGN. Option D is wrong because AWS Database Migration Service (DMS) is for databases, not servers.

Answer

AWS CloudFormation to recreate the server configuration.

Answer

AWS Server Migration Service (SMS).

Answer

AWS Database Migration Service (AWS DMS) for the database and manual server migration.

Question 13

A company is migrating an on-premises Oracle database to Amazon RDS for Oracle. The database is 2 TB in size and the company has a 1 Gbps AWS Direct Connect connection. They need to minimize downtime. Which approach should the solutions architect recommend?

Accepted Answer

Use AWS DMS with full load followed by ongoing replication using change data capture (CDC). AWS Database Migration Service (DMS) with change data capture (CDC) allows continuous replication and minimal downtime. Export/import would cause downtime. AWS Schema Conversion Tool (SCT) is for schema conversion, not data migration. Snowball is for offline data transfer and would delay the process.

Answer

Export the database using Oracle Data Pump and import into RDS

Answer

Use AWS Snowball Edge to transfer the database files and then restore to RDS

Answer

Use AWS Schema Conversion Tool to convert the schema and AWS DMS for data migration without CDC

Question 14

A company is modernizing a legacy CRM application to a microservices architecture on AWS. They want to use AWS Lambda for compute and Amazon API Gateway for the API layer. Which THREE design patterns should they consider? (Select THREE.)

Accepted Answer

Decompose the monolith into separate Lambda functions for each business capability. The three design patterns for this serverless microservices architecture are: B (Decompose the monolith into separate Lambda functions for each business capability), C (Use API Gateway to expose each microservice as a REST API), and E (Use AWS Step Functions to orchestrate multiple Lambda functions). Options A and D are incorrect: A (ElastiCache) is a caching solution, not a core microservices pattern, and D (EC2 Auto Scaling) introduces server-based compute, which contradicts the serverless approach.

Answer

Use Amazon ElastiCache for session state management

Answer

Use EC2 Auto Scaling groups for each microservice

Question 15

A company is migrating a legacy on-premises application to AWS. The application currently runs on a Windows Server with a SQL Server database. The company wants to minimize changes to the application code. Which migration strategy should the company use?

Accepted Answer

Rehost (lift-and-shift). Rehosting (lift-and-shift) involves moving the application as-is to AWS, minimizing code changes. Replatforming (lift-and-resize) may involve some changes, but rehosting requires the least modification. Refactoring and rebuilding involve significant changes.

Answer

Refactor / re-architect

Answer

Replatform (lift-and-resize)

Answer

Rebuild
