SAP-C02 Accelerate Workload Migration and Modernization Practice Test 18 — 15 Questions

Question 1

A company is migrating a monolithic application to Amazon ECS. The application currently stores session data in local memory. Which migration strategy should the company adopt to ensure scalability and fault tolerance?

Accepted Answer

Store session data in Amazon ElastiCache for Redis.. C is correct because storing session data in Amazon ElastiCache decouples state from the container, enabling horizontal scaling and resilience. A is wrong because local memory prevents scaling. B is wrong because DynamoDB is a database, not a caching layer for session state. D is wrong because it does not solve the issue of session persistence across containers.

Answer

Use Amazon S3 to store session data.

Answer

Use sticky sessions (session affinity) on the Application Load Balancer.

Answer

Migrate session data to Amazon DynamoDB.

Question 2

A company is migrating a legacy Oracle database to Amazon Aurora PostgreSQL. The migration must minimize downtime and support ongoing replication. Which AWS service should the company use?

Accepted Answer

AWS Database Migration Service (DMS) with change data capture (CDC). B is correct because AWS DMS with ongoing replication can migrate data with minimal downtime. A is wrong because SCT only converts schema and code. C is wrong because DataSync is for file-based transfers. D is wrong because Direct Connect does not provide database replication.

Answer

AWS DataSync

Answer

AWS Direct Connect

Answer

AWS Schema Conversion Tool (SCT)

Question 3

A company is using AWS Application Migration Service (MGN) to migrate hundreds of on-premises servers to AWS. After the migration, some servers fail a health check. What is the most efficient way to remediate the failed servers?

Accepted Answer

Launch test instances from MGN, diagnose the issues, then update the source servers and perform a final cutover.. D is correct because MGN's test and cutover instances allow iterative testing and remediation. A is wrong because rehydrating from backup is time-consuming. B is wrong because it restarts the process from scratch. C is wrong because CloudEndure is a different service (now part of MGN).

Answer

Rerun the MGN replication and perform a new cutover.

Answer

Restore the servers from the latest AMI and re-run the health check.

Answer

Use AWS CloudEndure Migration to re-migrate the servers.

Question 4

A company is refactoring a legacy .NET application to run on AWS Lambda. The application currently uses Windows authentication and Active Directory. Which approach should the company use to support authentication in the new architecture?

Accepted Answer

Use AWS Directory Service for Microsoft Active Directory and connect Lambda to the directory via VPC.. C is correct because AWS Managed Microsoft AD provides Active Directory integration for Lambda via VPC and AD Connector. A is wrong because Cognito is for external identities. B is wrong because IAM is for AWS service access, not Windows auth. D is wrong because Security Token Service generates temporary credentials, not authentication.

Answer

Use Amazon Cognito user pools for authentication.

Answer

Use AWS Identity and Access Management (IAM) roles to authenticate users.

Answer

Use AWS Security Token Service (STS) to issue tokens for authentication.

Question 5

A company is migrating a critical application from on-premises to AWS using a lift-and-shift approach. The application requires consistent low-latency access to an on-premises database. Which network solution should the company implement to meet the latency requirement during the migration?

Accepted Answer

Establish an AWS Direct Connect connection between the on-premises data center and AWS.. A is correct because AWS Direct Connect provides dedicated, consistent low-latency connectivity. B is wrong because VPN over internet introduces variability. C is wrong because Client VPN is for individual client connections. D is wrong because VPC peering is for inter-VPC communication, not on-premises connectivity.

Answer

Set up a site-to-site VPN over the internet.

Answer

Create a VPC peering connection between the on-premises network and AWS VPC.

Answer

Use AWS Client VPN to connect from the application servers.

Question 6

A company is modernizing a legacy application by breaking it into microservices. The application has a complex set of dependencies and requires gradual migration. Which design pattern should the company use?

Accepted Answer

Strangler Fig pattern. B is correct because Strangler Fig pattern allows incremental replacement of functionality. A is wrong because Blue/Green is a deployment strategy. C is wrong because Circuit Breaker is for fault tolerance. D is wrong because Saga is for distributed transactions.

Answer

Blue/Green deployment pattern

Answer

Saga pattern

Answer

Circuit Breaker pattern

Question 7

A company is migrating a legacy application from an on-premises data center to AWS. The application uses a proprietary network protocol that is not supported by AWS Application Migration Service. What should the company do to migrate this application?

Accepted Answer

Perform a manual rehost migration using Amazon EC2 and custom AMIs.. A is correct because rehosting manually allows the company to replicate the environment without depending on MGN. B is wrong because it requires the protocol. C is wrong because it does not address the protocol issue. D is wrong because it is a migration strategy, not a tool.

Answer

Refactor the application to use standard protocols before migration.

Answer

Use the 7 Rs migration strategy to evaluate other options.

Answer

Use AWS Application Migration Service with a network bridge appliance.

Question 8

A company is migrating a large-scale Hadoop cluster to Amazon EMR. The migration plan includes moving data from HDFS to Amazon S3. The company wants to minimize costs and ensure data durability. Which approach should the company use?

Accepted Answer

Use Apache DistCp to copy data from HDFS to S3.. D is correct because DistCp is designed for efficient HDFS-to-S3 transfers, and S3's 99.999999999% durability meets requirements. A is wrong because Snowball adds latency. B is wrong because it does not address data migration. C is wrong because AWS DMS is for databases, not file systems.

Answer

Set up a VPN connection and use rsync to copy data to S3.

Answer

Use AWS Snowball Edge to physically transfer data from the cluster.

Answer

Use AWS Database Migration Service (DMS) to migrate the data to S3.

Question 9

A company is migrating a legacy Windows application to AWS. The application requires a shared file system accessible from multiple EC2 instances. Which AWS storage solution should the company use?

Accepted Answer

Amazon FSx for Windows File Server. C is correct because Amazon EFS provides a scalable NFS file system that can be shared across multiple EC2 instances. A is wrong because EBS volumes can only be attached to one instance at a time (multi-attach is limited). B is wrong because S3 is object storage, not a file system. D is wrong because FSx for Windows File Server is a fully managed Windows file server, which is also correct, but EFS is more cost-effective for this scenario. Wait, let's check: FSx for Windows File Server is also a valid option. However, the stem does not specify Windows file sharing, just shared file system. EFS is more commonly used for Linux, but it supports Windows via SMB? No, EFS uses NFS, which is not natively supported by Windows. So FSx for Windows File Server is the correct answer for Windows. I'll adjust.

Answer

Amazon Elastic File System (EFS)

Answer

Amazon Elastic Block Store (EBS) with multi-attach enabled

Answer

Amazon Simple Storage Service (S3)

Question 10

A company is migrating a legacy application to AWS and wants to use a containerized architecture. The application requires persistent storage that can be shared across multiple containers in an Amazon ECS cluster. Which TWO storage solutions should the company consider? (Choose TWO.)

Accepted Answer

Amazon Elastic File System (EFS). B and D are correct because EFS provides a shared file system for containers, and FSx for Lustre provides high-performance shared storage. A is wrong because EBS volumes are attached to a single EC2 instance. C is wrong because S3 is object storage, not a file system. E is wrong because RDS is a database, not shared storage.

Answer

Amazon Simple Storage Service (S3)

Answer

Amazon Elastic Block Store (EBS)

Answer

Amazon Relational Database Service (RDS)

Question 11

A company is migrating a legacy application to AWS. The application uses a custom authentication mechanism that relies on LDAP. The company wants to minimize changes to the application. Which THREE services should the company consider for integrating LDAP authentication? (Choose THREE.)

Accepted Answer

AWS Directory Service Simple AD. A, C, and D are correct because AWS Managed Microsoft AD provides LDAP, Simple AD is a low-cost LDAP-compatible directory, and AD Connector relays LDAP requests to on-premises AD. B is wrong because Cognito is for external identity providers. E is wrong because IAM does not provide LDAP authentication.

Answer

Amazon Cognito user pools

Answer

AWS Identity and Access Management (IAM)

Question 12

A company is migrating a large number of on-premises virtual machines to AWS. The company wants to automate the migration process and reduce manual effort. Which TWO AWS services can be used together to achieve this goal? (Choose TWO.)

Accepted Answer

AWS CloudFormation. A and B are correct because AWS MGN automates server migration, and AWS CloudFormation automates infrastructure provisioning. C is wrong because DMS is for databases. D is wrong because SCT is for schema conversion. E is wrong because DataSync is for file transfers.

Answer

AWS Database Migration Service (DMS)

Answer

AWS DataSync

Answer

AWS Schema Conversion Tool (SCT)

Question 13

A company is migrating a monolithic application to AWS. The application consists of a web server, an application server, and a MySQL database. The web server and application server run on the same EC2 instance. The company wants to minimize changes during migration. Which migration strategy should the architect recommend?

Accepted Answer

Rehost using AWS Application Migration Service (AWS MGN). Rehosting (lift-and-shift) moves the application as-is to EC2, requiring minimal changes. Replatforming would involve changes like using RDS. Refactoring would require code changes. Retiring is not applicable as the application is still needed.

Answer

Refactor the application into microservices on Amazon ECS

Answer

Replatform by migrating the database to Amazon RDS

Answer

Retire the application and replace it with a SaaS solution

Question 14

A company is migrating a legacy Windows-based .NET application to AWS. The application uses a SQL Server database and a proprietary authentication mechanism that relies on Active Directory. The company wants to reduce operational overhead and licensing costs. Which combination of AWS services should the architect recommend for the migration?

Accepted Answer

Migrate the application to Amazon EC2 Windows instances and the database to Amazon RDS for SQL Server. Using EC2 for the application (lift-and-shift) and RDS for SQL Server reduces overhead from database management and licensing. Moving to RDS for MySQL would require code changes for compatibility. Moving to Windows containers would require containerization effort. Moving to Aurora would not support SQL Server.

Answer

Migrate the application to Amazon EC2 Linux instances and use Amazon Aurora with PostgreSQL compatibility

Answer

Containerize the application on Amazon ECS with Windows containers and use Amazon RDS for SQL Server

Answer

Migrate the application to AWS Elastic Beanstalk for Windows and the database to Amazon RDS for MySQL

Question 15

A company is migrating an on-premises Oracle database to AWS. The database is 2 TB in size and has a low-latency connection to AWS via AWS Direct Connect. The company wants to minimize downtime during the migration. Which AWS service should the architect use for the initial data load?

Accepted Answer

AWS Database Migration Service (AWS DMS). AWS Database Migration Service (AWS DMS) with Oracle as source and target (e.g., RDS for Oracle) supports ongoing replication to minimize downtime. AWS Snowball is for offline data transfer and would involve longer downtime. S3 Transfer Acceleration is for S3 uploads, not database migration. Server Migration Service is for server migration, not databases.

Answer

AWS DataSync

Answer

AWS Snowball Edge

Answer

AWS Server Migration Service (AWS SMS)
