SAP-C02 Accelerate Workload Migration and Modernization Practice Test 3 — 15 Questions

Question 1

Refer to the exhibit. A company has this IAM policy attached to a group. A user in the group tries to terminate an EC2 instance in us-east-1 with the tag 'Environment: staging'. What happens?

Accepted Answer

The termination is denied because the condition requires the 'Environment' tag to be 'production'.. The IAM policy likely includes a condition that requires the EC2 instance's 'Environment' tag to be 'production' for the TerminateInstances action. Since the instance has the tag 'Environment: staging', the condition evaluates to false, and the action is denied. The policy may also have a Resource element that specifies the instance ARN, but the key point is the condition mismatch.

Answer

The instance is terminated because the policy allows TerminateInstances.

Answer

The termination is denied because the Resource is not the instance's ARN.

Answer

The instance is terminated because the condition is not evaluated.

Question 2

Refer to the exhibit. A solutions architect runs the AWS CLI command and receives the output shown. The instance was stopped 2 hours ago. The company wants to minimize costs. What should the architect do next?

Accepted Answer

Keep the instance stopped; only storage costs apply.. When an EC2 instance is stopped, you are not charged for instance usage hours, but you continue to pay for any attached EBS volumes. Thus, keeping the instance stopped minimizes costs while retaining the instance configuration and data. Option B (terminate) would delete the instance and its attached volumes, potentially incurring data loss and additional costs for snapshots. Option C (start) would resume instance charges and EBS volume costs. Option D (hibernate) is not available from a stopped state; hibernation can only be initiated from a running instance and saves the memory state to an EBS volume, but it also incurs charges for that volume.

Answer

Terminate the instance to avoid any further charges.

Answer

Start the instance to verify it works.

Answer

Hibernate the instance to save memory state.

Question 3

Refer to the exhibit. A company creates this CloudFormation stack. After 30 days, what happens to objects with the prefix 'logs/'?

Accepted Answer

They are moved to the GLACIER storage class.. Objects with the prefix 'logs/' are moved to the GLACIER storage class after 30 days because the lifecycle rule specifies a transition to GLACIER after 30 days. This is a standard S3 lifecycle action that automatically transitions objects to cheaper storage classes based on age.

Answer

They are deleted because of the lifecycle rule.

Answer

They remain in Standard storage because versioning is enabled.

Answer

They are deleted after 30 days because no expiration is defined.

Question 4

A company is migrating a legacy on-premises application to AWS. The application uses a proprietary database that is not supported by Amazon RDS. The migration must minimize downtime and require minimal changes to the application. Which migration strategy should the company use?

Accepted Answer

Rehost the application on Amazon EC2 instances and migrate the database using AWS Database Migration Service (DMS) with ongoing replication.. Rehosting (lift-and-shift) the application on Amazon EC2 allows the proprietary database to run without modification. Using AWS Database Migration Service (DMS) with ongoing replication minimizes downtime by keeping the database synchronized until cutover. Option A is incorrect because the proprietary database is not supported by Amazon RDS, so migrating to RDS is not feasible without changing the database engine. Option C is incorrect because refactoring to Amazon Aurora would require modifying the application code to use Aurora's query interface, resulting in significant changes. Option D is incorrect because replacing the database with Amazon DynamoDB would necessitate rewriting the entire database access layer, which is not minimal change.

Answer

Migrate the database to Amazon RDS with a compatible engine and modify connection strings.

Answer

Refactor the application to use Amazon Aurora and modify the code to use the Aurora query interface.

Answer

Replace the database with Amazon DynamoDB and rewrite database access layer.

Question 5

A company is planning to migrate a large-scale e-commerce platform from on-premises to AWS. The platform includes a web tier, application tier, and a MySQL database. The company needs to ensure high availability and scalability. Which combination of AWS services should the company use to modernize the application architecture while minimizing operational overhead?

Accepted Answer

Use Application Load Balancer, Amazon ECS with Fargate for both web and application tiers, and Amazon Aurora MySQL.. It uses a managed container service (ECS with Fargate) for both web and application tiers, eliminating server management overhead, and Amazon Aurora MySQL provides a MySQL-compatible, highly available, and scalable managed database. Option A is incorrect because although it includes a load balancer and ECS with Fargate for the application tier, it uses unmanaged EC2 instances for the web tier, increasing operational overhead. Option C is incorrect because it proposes DynamoDB, which is NoSQL and not suitable for a MySQL-based e-commerce platform. Option D is incorrect because it uses EC2 instances for both tiers, requiring more manual management compared to a containerized solution.

Answer

Use Elastic Load Balancer, Amazon EC2 instances for the web tier, and Amazon ECS with Fargate for the application tier, and Amazon RDS for MySQL.

Answer

Use Amazon CloudFront, Amazon EC2 instances for the application tier, and Amazon DynamoDB.

Answer

Use Amazon EC2 Auto Scaling groups for both web and application tiers, and Amazon RDS for MySQL with Multi-AZ.

Question 6

A company is migrating a legacy .NET application to AWS. The application currently runs on Windows Server and uses a SQL Server database. The company wants to minimize licensing costs and operational overhead. Which migration strategy should the company use?

Accepted Answer

Rehost the application on Amazon EC2 Windows instances with SQL Server using License Mobility.. Rehosting the application on Amazon EC2 Windows instances with SQL Server using License Mobility is the correct choice because it minimizes licensing costs by leveraging existing Microsoft licenses through License Mobility, and it minimizes operational overhead by not requiring application changes. This is a lift-and-shift approach that preserves the current architecture while taking advantage of AWS's licensing benefits.

Answer

Replatform using Docker containers on Amazon ECS with Windows containers.

Answer

Replatform the application by moving the database to Amazon RDS for SQL Server and the application to Elastic Beanstalk.

Answer

Refactor the application to .NET Core and deploy on Amazon Linux with SQL Server.

Question 7

A company is migrating a distributed application that uses a custom TCP protocol between components. The application is deployed on-premises across multiple servers. The company wants to use AWS without modifying the application code. Which approach should the company take to migrate the application while maintaining low latency between components?

Accepted Answer

Use Amazon EC2 instances in a Placement Group within a single VPC to ensure low latency.. Using a Placement Group ensures that EC2 instances are placed close together within the same Availability Zone, minimizing network latency and maximizing throughput for the custom TCP protocol. This allows the application to run unchanged on AWS. Option B is incorrect because Direct Connect connects on-premises to AWS, but the application components would still be separated by network distance, increasing latency. Option C is incorrect because VPC Peering connects different VPCs, which does not guarantee low latency within a single VPC. Option D is incorrect because a VPN is used for secure connectivity over the internet, which introduces higher latency and is not necessary for components within the same VPC.

Answer

Use AWS Direct Connect to connect the on-premises servers to AWS and keep the application on-premises.

Answer

Use VPC Peering to connect the application components across different VPCs.

Answer

Use a VPN connection between the on-premises environment and AWS VPC.

Question 8

A company is migrating a legacy application to AWS. The application runs on Windows Server and uses a shared file system for storage. The company wants to modernize the application by using a managed file storage service that is POSIX-compliant and can be accessed by multiple EC2 instances concurrently. Which TWO AWS services meet these requirements? (Choose TWO.)

Accepted Answer

Amazon FSx for Lustre. Amazon FSx for Lustre (B) is correct because it is a fully managed, POSIX-compliant parallel file system designed for high-performance workloads, and it can be mounted and accessed concurrently by multiple EC2 instances, which fits the migration scenario. Amazon EFS (E) is also correct because it is a managed, POSIX-compliant, elastic NFS file system that supports concurrent access from many EC2 instances, making it suitable for a shared file system. Amazon EBS (A) is not correct because it provides block storage volumes that are typically attached to a single EC2 instance at a time, not a shared POSIX file system for concurrent multi-instance access. Amazon S3 (C) and Amazon S3 Glacier (D) are object storage services, not POSIX-compliant file systems, and they are not mounted as shared file systems by multiple EC2 instances in the way the application requires.

Answer

Amazon EBS

Answer

Amazon S3

Answer

Amazon S3 Glacier

Question 9

A company is migrating 50 on-premises web applications to AWS. Each application has a different OS and middleware. The migration must minimize downtime and use a pay-as-you-go model. Which AWS service should the company use to standardize the deployment of these applications?

Accepted Answer

AWS Application Migration Service. AWS Application Migration Service automates lift-and-shift migration of applications from on-premises to AWS, minimizing downtime and supporting heterogeneous environments with a pay-as-you-go model. Option A is wrong because AWS CloudFormation is for infrastructure as code, not for migrating applications. Option C is wrong because AWS Server Migration Service is deprecated and lacks the features of Application Migration Service. Option D is wrong because AWS Database Migration Service is specifically for databases, not general applications.

Answer

AWS CloudFormation

Answer

AWS Server Migration Service

Answer

AWS Database Migration Service

Question 10

A company is migrating a .NET application from Windows Server to AWS. The application uses SQL Server and needs to run on Amazon EC2. The company wants to reduce licensing costs. Which Amazon EC2 instance type should the company use?

Accepted Answer

T3. T3 instances are burstable and cost-effective for workloads with moderate CPU usage, making them ideal for reducing licensing costs for a .NET application on SQL Server. Option A (C5) is compute-optimized and may be overkill, increasing costs. Option C (A1) is ARM-based and may not support .NET. Option D (I3) is storage-optimized and not cost-effective for this scenario.

Answer

C5

Answer

A1

Answer

I3

Question 11

A company is migrating a web application to AWS and wants to use Amazon ECS with Fargate. The application needs to store session state. Which AWS service should the company use for session state management?

Accepted Answer

Amazon ElastiCache for Redis. Amazon ElastiCache for Redis is the canonical AWS service for session state because it provides sub-millisecond, in-memory key-value storage with native TTL support, which is exactly what session tokens need. Redis also supports data structures (hashes, sorted sets) and optional persistence, making it suitable for high-throughput session workloads across multiple Fargate tasks.

Answer

Amazon S3

Answer

Amazon DynamoDB

Answer

Amazon RDS

Question 12

A company is migrating a virtual machine from on-premises to AWS. The VM runs Windows Server 2012 R2. The company wants to minimize changes to the VM. Which AWS service should the company use to migrate the VM?

Accepted Answer

AWS Server Migration Service. AWS Server Migration Service (SMS) is an agentless service that specializes in migrating virtual machines from on-premises environments to AWS with minimal changes to the VM configuration. Option B is incorrect because AWS Database Migration Service (DMS) is designed for database migrations, not entire VMs. Option C is incorrect because AWS CloudEndure Migration is a legacy service that has been superseded by AWS Application Migration Service. Option D is incorrect because although AWS Application Migration Service (MGN) can also migrate VMs, it typically requires installing an agent on the source VM, which introduces changes; SMS minimizes changes by using agentless replication.

Answer

AWS Database Migration Service

Answer

AWS CloudEndure Migration

Answer

AWS Application Migration Service

Question 13

A company is migrating a large number of files from on-premises to Amazon S3. The files are in a network-attached storage (NAS) system with a 1 Gbps connection to the internet. The company has a 2-week deadline to complete the migration. Which TWO services should the company use to accelerate the migration? (Choose TWO.)

Accepted Answer

AWS DataSync. AWS DataSync (A) is correct because it is a purpose-built online data transfer service that moves large volumes of files from NAS systems to Amazon S3 over the network, using parallel, multi-threaded transfers and built-in integrity verification to maximize throughput on the existing 1 Gbps link. AWS Snowball Edge (C) is correct because it is an offline, petabyte-scale physical transfer device that bypasses the limited 1 Gbps internet connection entirely, which is essential to meet the aggressive 2-week deadline when the dataset is very large. AWS Transfer Family (B) is not appropriate because it provides managed SFTP/FTPS/FTP endpoints for ongoing file transfers rather than a bulk migration acceleration mechanism. AWS Database Migration Service (D) is for migrating databases, not file shares, and AWS Direct Connect (E) is a dedicated network connection that typically takes weeks to provision and would not be ready in time to accelerate this migration.

Answer

AWS Transfer Family

Answer

AWS Database Migration Service

Answer

AWS Direct Connect

Question 14

A company is modernizing a legacy application by breaking it into microservices. The application currently uses a single relational database. The company wants to adopt a microservices architecture with separate databases per service. Which THREE patterns should the company consider? (Choose THREE.)

Accepted Answer

API Gateway. Option A, API Gateway, is correct because in a microservices architecture it provides a single entry point that routes client requests to the appropriate services, handles cross-cutting concerns like authentication, rate limiting, and protocol translation, which is essential when clients would otherwise need to know about many independently deployable services. Option C, Database per Service, is correct because it is the core data-management pattern for microservices: each service privately owns its schema and data store, exposing data only through its API, which enforces loose coupling and independent deployability instead of the legacy single relational database. Option D, Event Sourcing, is correct because it persists state as an append-only sequence of domain events, which enables reliable asynchronous communication and data consistency across separate service databases (often combined with CQRS) when services must react to each other's changes without shared tables. Option B, Shared Database, is not correct because a single shared database couples services at the schema level, creating deployment and scaling bottlenecks that directly contradict the goal of separate databases per service. Option E, CQRS, while commonly paired with Event Sourcing, is not marked correct here; it is a read/write model separation pattern rather than one of the three patterns specifically called for in this scenario.

Answer

Shared Database

Answer

Command Query Responsibility Segregation (CQRS)

Question 15

A company is migrating a web application to AWS and wants to use a content delivery network (CDN) to improve performance. Which TWO AWS services can be used together to achieve this? (Choose TWO.)

Accepted Answer

Amazon CloudFront. Amazon CloudFront (A) is AWS's content delivery network service, so it is the core service that caches and distributes the web application's content from edge locations to reduce latency; it is correct because the scenario explicitly requires a CDN. An Application Load Balancer (E) is correctly paired with CloudFront because it can serve as the custom origin that CloudFront forwards requests to, distributing traffic across backend targets in the web application tier. Amazon Route 53 (B) is a DNS service, not a CDN, so it does not itself deliver cached content even though it can route users to CloudFront. Amazon S3 (C) is object storage that can act as an origin for static content, but it is not a CDN and is not one of the two services that together fulfill the CDN requirement. AWS WAF (D) is a web application firewall that filters HTTP traffic, not a content delivery network, so it does not satisfy the scenario.

Answer

Amazon Route 53

Answer

Amazon S3

Answer

AWS WAF
