SAP-C02 Accelerate Workload Migration and Modernization Practice Test 16 — 15 Questions

Question 1

A company is migrating a stateful firewall appliance to AWS. The appliance currently inspects traffic between multiple on-premises segments. In AWS, the company wants to deploy the appliance in a VPC to inspect traffic between subnets. Which architecture should the company use to ensure that the appliance can inspect all traffic?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Deploy the appliance behind a Gateway Load Balancer in an inspection VPC and use a Transit Gateway to route traffic through it.. A Gateway Load Balancer (GWLB) can be deployed in an inspection VPC and used with a Transit Gateway to route traffic from subnets through the appliance for inspection. Option A is wrong because an Application Load Balancer cannot inspect traffic and is designed for HTTP/HTTPS. Option C is wrong because a Network Load Balancer does not inspect traffic; it forwards traffic without inspection. Option D is wrong because VPC Gateway Endpoints are used to access AWS services privately, not for traffic inspection.

Answer

Deploy the appliance behind an Application Load Balancer and configure the VPC route tables.

Answer

Deploy the appliance behind a Network Load Balancer and configure the VPC route tables to send traffic to the NLB.

Answer

Use VPC Gateway Endpoints to route traffic through the appliance.

Question 2

A company is migrating a web application to AWS and wants to use a multi-tier architecture with an Auto Scaling group of EC2 instances behind an Application Load Balancer. The company needs to store session state for the application. Which TWO approaches should the company use to store session state in a scalable and highly available manner? (Choose TWO.)

Accepted Answer

Use Amazon DynamoDB with on-demand capacity.. Option A is correct because Amazon DynamoDB with on-demand capacity provides a fully managed, serverless, highly available key-value store that scales automatically with traffic, making it ideal for persisting session state across an Auto Scaling group of EC2 instances behind an ALB. Option D is correct because Amazon ElastiCache for Redis with replication offers an in-memory, low-latency, highly available session store with a primary node and read replicas, and it supports Multi-AZ failover so sessions survive node failures. Option B is incorrect because an EC2 instance store is ephemeral, tied to a single instance, and loses data on stop/termination, so it cannot provide shared or durable session state. Option C is incorrect because EBS snapshots are point-in-time backups, not a live shared session store, and cannot be concurrently attached across multiple instances for session access. Option E is incorrect because Amazon RDS for MySQL with Multi-AZ provides a relational database with failover, but it is not the optimal scalable session store and lacks the low-latency, purpose-built session handling of DynamoDB or ElastiCache.

Answer

Use an EC2 instance store for each instance.

Answer

Use Amazon EBS snapshots shared across instances.

Answer

Use Amazon RDS for MySQL with Multi-AZ.

Question 3

A company is migrating an on-premises Microsoft SQL Server database to Amazon RDS for SQL Server. They need to minimize downtime and ensure data consistency. Which AWS service should they use for the migration?

Accepted Answer

AWS Database Migration Service (DMS). (AWS DMS) is correct because it supports homogeneous migrations with minimal downtime using continuous replication. Option A (DataSync) is for file-based data. Option B (SCT) only provides schema conversion. Option D (Glue) is for ETL jobs.

Answer

Answer

AWS Schema Conversion Tool (SCT)

Answer

AWS Glue

Question 4

A company is moving its application from on-premises to AWS. They want to use the same third-party software licenses on AWS. Which AWS purchasing option allows them to bring their own licenses?

Accepted Answer

Dedicated Hosts. (Dedicated Hosts) is correct because it provides visibility and control over physical servers, allowing you to use your own licenses per socket/core. Option A (Savings Plans) is just a billing discount. Option C (Spot Instances) are interruptible. Option D (Reserved Instances) is also a billing discount and does not provide the license flexibility of Dedicated Hosts.

Answer

Savings Plans

Answer

Spot Instances

Answer

Reserved Instances

Question 5

A company is migrating a web application to AWS and wants to automatically scale the application based on CPU utilization. The application runs on a set of EC2 instances behind an Application Load Balancer. Which combination of AWS services should they use?

Accepted Answer

Auto Scaling group with a simple scaling policy based on CloudWatch CPU alarm. Auto Scaling group with a simple scaling policy based on a CloudWatch CPU alarm. This directly scales EC2 instances in response to CPU utilization, providing automatic scaling. Option A is incorrect because AWS Lambda with scheduled scaling does not dynamically respond to CPU utilization; it's time-based. Option B (Amazon CloudFront) is a content delivery network, not a scaling mechanism. Option C (Elastic Beanstalk) manages environments but the underlying scaling relies on Auto Scaling groups; the question asks for the combination of services, and the core scaling service is the Auto Scaling group. Therefore, D is the correct choice.

Answer

AWS Lambda with scheduled scaling

Answer

Amazon CloudFront with origin scaling

Answer

AWS Elastic Beanstalk with environment scaling

Question 6

A company is migrating a large-scale .NET application to AWS. The application uses Windows authentication and requires Active Directory integration. The company wants to reduce operational overhead. Which migration approach should they use?

Accepted Answer

Rehost on EC2 with AWS Managed Microsoft AD. (Rehost on EC2 with AWS Managed Microsoft AD) is correct because it provides Active Directory integration without the need to manage domain controllers, reducing operational overhead. Option A (Rehost on EC2 with on-premises AD via VPN) still requires managing on-premises resources and doesn't fully reduce overhead. Option C (Replatform to use Amazon Cognito) is aimed at web identity federation, not traditional Windows AD authentication. Option D (Replatform to AWS Elastic Beanstalk with Amazon Lightsail) does not support Windows authentication or AD integration effectively.

Answer

Rehost on EC2 with on-premises AD via VPN

Answer

Replatform to use Amazon Cognito for authentication

Answer

Replatform to AWS Elastic Beanstalk with Amazon Lightsail

Question 7

A company is migrating an e-commerce website to AWS. The website has a MySQL database. The company wants to automate the migration of the database schema and data. Which AWS service should they use?

Accepted Answer

AWS Database Migration Service (DMS). (AWS Database Migration Service) is correct because it automates data migration and can convert schema using SCT. Option A (AWS Glue) is for ETL, not database migration. Option C (AWS Data Pipeline) is for data processing. Option D (AWS Schema Conversion Tool) converts schema but does not migrate data.

Answer

AWS Glue

Answer

AWS Data Pipeline

Answer

AWS Schema Conversion Tool (SCT)

Question 8

A company is moving a legacy application that uses a shared file system to AWS. The application requires POSIX-compliant file storage that can be accessed by multiple EC2 instances simultaneously. Which AWS storage service should they use?

Accepted Answer

Amazon EFS. (Amazon EFS) is correct because it provides a scalable, POSIX-compliant NFS file system that can be accessed by multiple EC2 instances simultaneously. Option A (Amazon FSx for Windows File Server) uses SMB protocol and is not POSIX-compliant. Option C (Amazon EBS with Multi-Attach) only supports a limited number of instances and has specific constraints, and it is not a fully managed shared file system. Option D (Amazon S3) is object storage and does not provide POSIX compliance.

Answer

Amazon FSx for Windows File Server

Answer

Amazon EBS with Multi-Attach

Answer

Amazon S3

Question 9

A company is migrating an on-premises Oracle database to Amazon Aurora PostgreSQL. They need to minimize downtime and ensure data integrity. Which AWS service should they use for the migration?

Accepted Answer

AWS Database Migration Service (DMS). AWS Database Migration Service (DMS) supports homogeneous and heterogeneous migrations with minimal downtime. Option A is wrong because SCT only helps with schema conversion, not the actual data migration. Option C is wrong because DataSync is for file storage, not databases. Option D is wrong because Snowball Edge is for large-scale offline data transfer, not online database migration.

Answer

AWS Schema Conversion Tool (SCT)

Answer

AWS DataSync

Answer

AWS Snowball Edge

Question 10

A company is using the 7 Rs strategy to migrate a monolithic application to AWS. They want to move the application to the cloud without modifying the code but plan to later refactor parts of it. Which migration strategy should they choose initially?

Accepted Answer

Rehost. Rehost (lift-and-shift) is the correct initial strategy because it moves the application to AWS without modifying any code, aligning with the company's goal to first migrate without changes and later refactor. Relocate (A) involves moving the hypervisor, not the application itself. Refactor (B) involves rewriting or re-architecting the application, which is not desired initially. Replatform (C) involves making some cloud optimizations that could require minor code changes.

Answer

Relocate

Answer

Refactor

Answer

Replatform

Question 11

A company is migrating a legacy .NET Framework 4.7 application to AWS. The application uses Windows authentication and COM+ components. Which migration approach is most suitable?

Accepted Answer

Use Windows containers on Amazon ECS with Amazon ECS-optimized Windows Server AMI. Windows containers on Amazon ECS with the ECS-optimized Windows Server AMI support .NET Framework applications and COM+ components, making them the most suitable migration approach. Option A is incorrect because replatforming to .NET Core on Linux would require significant code changes and does not support COM+. Option C is incorrect because AWS Lambda does not support full .NET Framework or COM+. Option D is incorrect because Linux containers cannot run Windows-based .NET Framework applications.

Answer

Replatform to .NET Core on AWS Elastic Beanstalk (Linux)

Answer

Refactor to run on AWS Lambda with .NET Core 3.1

Answer

Containerize with Linux containers on Amazon ECS

Question 12

A company is migrating an on-premises application to AWS. The application requires low-latency access to a file system that can be mounted by multiple EC2 instances simultaneously. Which AWS storage service should they use?

Accepted Answer

Amazon EFS. Amazon EFS is a fully managed, elastic NFS file system that can be mounted concurrently by thousands of EC2 instances across multiple Availability Zones, providing the shared low-latency POSIX access the application needs. It scales automatically and is the canonical AWS answer for multi-attach Linux file storage.

Answer

Amazon S3

Answer

Amazon FSx for Windows File Server

Answer

Amazon EBS

Question 13

A company is migrating a stateful web application to AWS. The application uses local storage for user sessions. Which AWS service can help make the application stateless and scalable?

Accepted Answer

Amazon ElastiCache. Amazon ElastiCache provides a managed in-memory cache that can store session data externally, allowing the web application to be stateless and scale horizontally. Amazon EBS volumes are attached to a single EC2 instance and cannot be shared across instances, so they do not help with statelessness. Amazon RDS is for relational databases and is not optimized for low-latency session state. Amazon S3 is an object store with higher latency and is not suitable for frequent session reads/writes.

Answer

Amazon EBS

Answer

Amazon RDS

Answer

Amazon S3

Question 14

A company is planning to migrate a Microsoft SQL Server database to Amazon RDS for SQL Server. They want to automate the migration process and minimize manual effort. Which AWS service should they use?

Accepted Answer

AWS Database Migration Service (DMS). AWS DMS can migrate SQL Server to RDS with minimal downtime. Option A is wrong because CloudEndure Migration is for server migration. Option B is wrong because DataSync is for file data. Option D is wrong because Schema Conversion Tool is for schema conversion.

Answer

AWS CloudEndure Migration

Answer

AWS DataSync

Answer

AWS Schema Conversion Tool (SCT)

Question 15

A company is migrating a containerized application to Amazon ECS. The application requires persistent storage that can be shared across multiple containers running on different EC2 instances. Which storage solution should they use?

Accepted Answer

Amazon EFS. Amazon EFS provides a fully managed, elastic NFS file system that can be mounted simultaneously by multiple EC2 instances across Availability Zones, making it the correct choice for shared persistent storage across containers on different hosts. ECS tasks on EC2 launch type can mount EFS volumes using the EFS mount helper, enabling concurrent read/write access. This satisfies the requirement for shared persistent storage that survives container restarts and is accessible from multiple nodes.

Answer
