SAP-C02 Accelerate Workload Migration and Modernization Practice Test 19 — 15 Questions

Question 1

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. Amazon FSx for Windows File Server provides a fully managed native Windows file system that supports the SMB protocol, which is required for legacy Windows applications to access shared file systems. Amazon EFS uses NFS, which is not natively supported by Windows. EBS with multi-attach is limited to a small number of instances and not ideal for file sharing. S3 is object storage and does not provide a traditional file system interface.

Answer

Amazon Elastic File System (EFS)

Answer

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

Answer

Amazon Simple Storage Service (S3)

Question 2

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). Amazon EFS provides a fully managed NFS file system that can be mounted by multiple Amazon ECS tasks across multiple availability zones, making it ideal for shared persistent storage. Amazon FSx for Lustre is a high-performance file system optimized for workloads such as machine learning and high-performance computing, and it also supports concurrent access from multiple ECS tasks. In contrast, Amazon EBS volumes are block-level storage that can only be attached to a single EC2 instance, so they cannot be shared across multiple containers unless using a cluster-aware file system like EFS. Amazon S3 is object storage and does not provide a POSIX-compatible file system interface required by many legacy applications. Amazon RDS is a managed database service, not a shared storage solution.

Answer

Amazon Simple Storage Service (S3)

Answer

Amazon Elastic Block Store (EBS)

Answer

Amazon Relational Database Service (RDS)

Question 3

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, B, and C are correct because AWS Directory Service Simple AD (A) provides a low-cost LDAP-compatible directory, AD Connector (B) relays LDAP requests to an on-premises Active Directory, and AWS Directory Service for Microsoft Active Directory (C) supports LDAP natively. D (Amazon Cognito user pools) is incorrect because it is designed for external identity providers (e.g., social or enterprise federation) and does not support direct LDAP integration. E (AWS Identity and Access Management) is incorrect because IAM manages permissions for AWS resources but does not provide LDAP authentication services.

Answer

Amazon Cognito user pools

Answer

AWS Identity and Access Management (IAM)

Question 4

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. AWS Application Migration Service (MGN) and AWS CloudFormation are correct. MGN automates the migration of virtual machines from on-premises to AWS. CloudFormation automates the provisioning of AWS infrastructure using infrastructure as code. AWS DMS is for database migrations, not server migration. AWS DataSync is for file transfers. AWS SCT is for schema conversion.

Answer

AWS Database Migration Service (DMS)

Answer

AWS DataSync

Answer

AWS Schema Conversion Tool (SCT)

Question 5

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 6

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 7

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)

Question 8

A company is planning to migrate a large-scale Hadoop cluster to Amazon EMR. The cluster currently processes batch jobs using a mix of MapReduce and Spark. The company wants to minimize changes to the existing code and operational processes. Which migration approach should the architect recommend?

Accepted Answer

Rehost the cluster on Amazon EMR using the same MapReduce and Spark configurations. Rehosting the Hadoop cluster on Amazon EMR with the same configuration allows the existing MapReduce and Spark code to run with minimal changes. Refactoring to use only Spark would require code changes. Replatforming to Amazon Redshift would change the architecture. Retiring and using Athena would require significant changes to data storage and queries.

Answer

Refactor all jobs to use only Apache Spark on Amazon EMR

Answer

Retire the cluster and use Amazon Athena for ad-hoc queries

Answer

Replatform the data processing to use Amazon Redshift Spectrum

Question 9

A company is migrating a legacy e-commerce application to AWS. The application includes a web tier, an application tier, and a MySQL database. The company wants to improve scalability and reduce operational overhead. The architect plans to use Amazon RDS for MySQL and refactor the application to use Auto Scaling for the web and application tiers. However, the application currently stores session state locally on the web servers. What should the architect do to address session state management in the new architecture?

Accepted Answer

Use Amazon ElastiCache for Redis to store session state. Using ElastiCache for Redis provides a centralized, scalable session store that works with Auto Scaling. Using sticky sessions (ELB session stickiness) is a workaround but less scalable and not recommended for Auto Scaling. Storing sessions in RDS would add database load. Storing in S3 is not suitable for low-latency session access.

Answer

Store session state in Amazon S3

Answer

Store session state in Amazon RDS for MySQL

Answer

Configure an Application Load Balancer with sticky sessions

Question 10

A company is migrating its on-premises virtual machines (VMs) to AWS. The company has 50 VMs running various operating systems and applications. The architect wants to use a service that automates the replication and conversion of the VMs to Amazon EC2 instances. Which AWS service should the architect use?

Accepted Answer

AWS Application Migration Service (AWS MGN). AWS Application Migration Service (AWS MGN) automatically replicates and converts VMs to EC2. AWS Server Migration Service (SMS) is an older service, but MGN is the recommended service for automated migration. AWS CloudEndure Migration has been rebranded as AWS Application Migration Service. AWS DataSync is for file transfers.

Answer

AWS DataSync

Answer

AWS Server Migration Service (AWS SMS)

Answer

AWS CloudEndure Migration

Question 11

A company is migrating a critical application to AWS. The application requires a relational database with high availability and automated failover. The company wants to use a fully managed database service. Which AWS service should the architect choose?

Accepted Answer

Amazon RDS Multi-AZ. Amazon RDS Multi-AZ provides high availability with automated failover. Amazon Aurora is also fully managed and provides high availability, but the question asks for a relational database service; both RDS and Aurora are valid, but RDS Multi-AZ is a direct fit for the requirement. DynamoDB is NoSQL. RDS Single-AZ does not provide failover. ElastiCache is for caching.

Answer

Amazon ElastiCache

Answer

Amazon DynamoDB

Answer

Amazon RDS Single-AZ

Question 12

A company is migrating a legacy CRM application from a colocation facility to AWS. The application uses a client-server architecture with a thick client installed on employee desktops. The company wants to reduce desktop administration and provide remote access. Which migration approach should the architect recommend?

Accepted Answer

Deploy the thick client on Amazon WorkSpaces and provide access to employees. Using Amazon WorkSpaces allows the thick client to run in a virtual desktop, providing remote access and reducing desktop management. Rehosting the application on EC2 and using a VPN does not address the thick client issue. Refactoring to a web application would require significant development. Retiring the application is not desired.

Answer

Refactor the application into a web application using AWS App Runner

Answer

Rehost the application on Amazon EC2 and provide VPN access to employees

Answer

Retire the application and use a SaaS alternative

Question 13

A company is migrating its on-premises data warehouse to Amazon Redshift. The data warehouse is currently running on a single large server with 10 TB of data. The company wants to minimize downtime and ensure data consistency. Which AWS service should the architect use to perform the migration?

Accepted Answer

AWS Database Migration Service (AWS DMS). AWS Database Migration Service (DMS) can migrate data from on-premises databases to Amazon Redshift with minimal downtime. AWS Snowball is for offline transfer and would cause more downtime. AWS Glue is for ETL, not direct migration. S3 Transfer Acceleration is for S3 uploads.

Answer

Amazon S3 Transfer Acceleration

Answer

AWS Glue

Answer

AWS Snowball Edge

Question 14

A company is planning a large-scale migration of hundreds of applications to AWS. Which TWO strategies should the architect consider to reduce migration risks?

Accepted Answer

Use a wave-based migration approach with defined groups and dependencies. A pilot migration allows testing the process on a small set of applications. A wave-based approach groups applications for migration and helps manage dependencies. Rolling back all migrations if issues occur is not practical. Migrating all at once increases risk. Using only rehosting may not be optimal for all applications.

Answer

Use only the rehosting strategy for all applications

Answer

Migrate all applications in a single wave to reduce coordination effort

Answer

Roll back all migrations if any application experiences issues

Question 15

An IAM policy allows a user to start and stop EC2 instances but denies terminating instances under a specific condition. Which action will the policy deny?

Accepted Answer

Terminating an EC2 instance in the eu-west-1 region. The Deny statement applies when the condition "StringNotEquals" is true, meaning the requested region is NOT us-east-1. So terminating an instance in a region other than us-east-1 is denied. Terminating in us-east-1 is allowed (since the condition is not met). Starting and stopping are allowed by the first statement.

Answer

Starting an EC2 instance in the us-west-2 region

Answer

Stopping an EC2 instance in the eu-west-1 region

Answer

Terminating an EC2 instance in the us-east-1 region
