SAP-C02 Accelerate Workload Migration and Modernization Practice Test 22 — 15 Questions

Question 1

A company is migrating a multi-tier web application to AWS. The application consists of a web tier, an application tier, and a database tier. The company wants to use AWS services to improve scalability and reduce management overhead. The web and application tiers run on Linux. The database is Oracle running on Linux. Which solution meets these requirements with the LEAST operational overhead?

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

Accepted Answer

Deploy the web and application tiers using AWS Elastic Beanstalk with an Auto Scaling group. Migrate the database to Amazon RDS for Oracle.. AWS Elastic Beanstalk automatically manages the capacity provisioning, load balancing, and scaling of the web and application tiers, significantly reducing management overhead. Amazon RDS for Oracle handles database administration tasks such as patching, backups, and replication. Option A (EC2 + Auto Scaling) requires manual configuration and management of EC2 instances, increasing operational overhead. Option B (ECS with Fargate) introduces containerization complexity that is not necessary for a straightforward migration and may require additional learning and orchestration. Option D (RDS Custom) provides more customization but at the cost of increased operational overhead compared to standard RDS. Therefore, Option C offers the least operational overhead.

Answer

Deploy web and application tiers on Amazon EC2 instances in an Auto Scaling group. Migrate the database to an Amazon RDS for Oracle DB instance.

Answer

Containerize the web and application tiers and deploy them on Amazon ECS with AWS Fargate. Migrate the database to Amazon RDS for Oracle.

Answer

Deploy web and application tiers on Amazon EC2 instances in an Auto Scaling group. Migrate the database to Oracle on Amazon RDS Custom.

Question 2

A company is migrating a critical application to AWS. The application requires consistent performance and low latency. The company has selected an instance type that meets the performance requirements. However, during testing, the application experiences variable performance due to CPU stealing from other instances on the same physical host. What should the company do to mitigate this issue?

Accepted Answer

Use Amazon EC2 Dedicated Hosts for the instances. Dedicated Hosts provide dedicated physical servers, eliminating CPU stealing. Option B (placement group) helps with network performance, not CPU isolation. Option C (T2/T3 unlimited) is for burstable instances, not dedicated. Option D (C5 instance) does not prevent CPU stealing.

Answer

Launch instances in a cluster placement group

Answer

Use T2 or T3 instances with the unlimited credit option

Answer

Switch to a compute-optimized instance type such as C5

Question 3

A company is migrating a large-scale batch processing workload from on-premises to AWS. The workload runs on a schedule and processes data files from an FTP server. The company wants to use AWS services that are serverless and event-driven to reduce operational overhead. The data files will be uploaded to an Amazon S3 bucket. Which solution meets these requirements?

Accepted Answer

Use Amazon S3 Event Notifications to invoke an AWS Lambda function that processes the file. Amazon S3 Event Notifications can directly invoke an AWS Lambda function to process the file upon upload. This is serverless and event-driven, meeting the requirements to reduce operational overhead. Option A (AWS Batch) is not serverless because it requires provisioning compute resources and does not directly trigger from S3 events in a serverless manner. Option C (AWS Glue) is designed for ETL and crawling, not for general batch processing of files. Option D (Step Functions) is used for orchestrating workflows, but the actual processing would still need a compute resource like EC2 or Lambda; using it with EC2 adds overhead and is not fully serverless.

Answer

Use Amazon S3 Event Notifications to invoke an AWS Batch job that processes the file

Answer

Use AWS Glue to crawl the S3 bucket and run an ETL job on a schedule

Answer

Use Amazon S3 Event Notifications to start an AWS Step Functions workflow that runs processing on Amazon EC2

Question 4

A company is migrating a legacy application to AWS. The application runs on a single Windows Server instance and uses a local MySQL database. The company wants to minimize changes to the application code. Which migration strategy should the company use?

Accepted Answer

Rehost the application on Amazon EC2 with MySQL installed on the same instance. Rehost (lift-and-shift) migrates the application as-is to EC2, keeping MySQL on the same instance to minimize code changes. Option B (Retire) is not a migration strategy. Option C (Refactor) requires code changes to adapt to serverless and DynamoDB. Option D (Replatform) moves the database to RDS, which may require code changes due to different database configuration or features.

Answer

Retire the application and replace it with a SaaS alternative

Answer

Refactor the application to use a serverless architecture with AWS Lambda and Amazon DynamoDB

Answer

Replatform the application by moving the database to Amazon RDS for MySQL

Question 5

A company is migrating a mission-critical application to AWS. The application requires a fixed IP address for whitelisting by external partners. The company plans to use an Application Load Balancer (ALB) to distribute traffic. However, ALB does not support static IP addresses. How can the company meet the requirement for static IP addresses while using the ALB?

Accepted Answer

Use AWS Global Accelerator with the ALB as an endpoint. Using AWS Global Accelerator provides static anycast IP addresses and directs traffic to the ALB, meeting the requirement for fixed IP whitelisting. Option A (replacing with NLB) would avoid the ALB entirely and may not be suitable for application-level traffic. Option C (Route 53 failover) does not provide static IP addresses for whitelisting. Option D (assigning Elastic IP to ALB) is not supported.

Answer

Replace the ALB with a Network Load Balancer (NLB) that has Elastic IP addresses

Answer

Use Amazon Route 53 with a failover routing policy

Answer

Assign Elastic IP addresses to the ALB

Question 6

A company is migrating a web application to AWS. The application uses a three-tier architecture with a web server, application server, and MySQL database. The company wants to ensure high availability by deploying across multiple Availability Zones. The web and application servers are stateless. Which solution provides the HIGHEST availability with the LEAST administrative effort?

Accepted Answer

Deploy web and application servers on EC2 instances in an Auto Scaling group across two AZs with an Application Load Balancer. Use Multi-AZ Amazon RDS for MySQL.. Deploying web and application servers on EC2 instances in an Auto Scaling group across two AZs with an Application Load Balancer ensures high availability and automatic scaling. Multi-AZ Amazon RDS for MySQL provides automatic failover for the database, minimizing administrative effort. Option B (deploying in one AZ) does not provide high availability across AZs. Option C (single large instance) is a single point of failure. Option D (using Elastic IPs and Route 53 health checks) requires manual intervention and is less automated than the ALB solution.

Answer

Deploy web and application servers on EC2 instances in an Auto Scaling group in one AZ. Use Amazon Route 53 latency-based routing to another region.

Answer

Deploy web, application, and database on a single large EC2 instance in one AZ. Take snapshots every hour.

Answer

Deploy web and application servers on EC2 instances in two AZs with Elastic IP addresses. Use Amazon Route 53 with health checks to route traffic.

Question 7

A company is migrating a large number of on-premises virtual machines (VMs) to AWS using AWS Application Migration Service (AWS MGN). During the initial replication, some VMs fail with the error 'Replication agent cannot communicate with the AWS MGN endpoint'. Which TWO actions should the company take to resolve this issue? (Choose TWO.)

Accepted Answer

Configure AWS PrivateLink VPC endpoints for AWS MGN in the target VPC. The correct actions are B and D. AWS Application Migration Service (MGN) requires the replication agent to communicate with the AWS MGN endpoint. If the source servers do not have outbound internet access (option D), you can configure AWS PrivateLink VPC endpoints for AWS MGN (option B) to establish connectivity without internet access. Option A (reinstalling the agent) is not a first troubleshooting step for connectivity issues. Option C (security group inbound rules) is about inbound traffic, but the agent initiates outbound connections. Option E (increasing CPU/memory) does not resolve communication failures.

Answer

Reinstall the AWS Replication Agent on the source servers

Answer

Ensure that the security group of the replication servers allows inbound traffic from the source servers

Answer

Increase the instance type of the source servers to provide more CPU and memory

Question 8

A company is migrating a legacy .NET Framework 4.7 application to AWS. The application uses Windows Server 2012 R2, IIS, and SQL Server 2014. The company wants to modernize the application to reduce licensing costs and operational overhead. Which THREE actions should the company take? (Choose THREE.)

Accepted Answer

Rehost the application on Amazon EC2 Windows instances with SQL Server Web Edition. Rehosting the application on Amazon EC2 Windows instances with SQL Server Web Edition reduces licensing costs compared to the current Enterprise or Standard edition. Option C is correct because rebuilding the application on .NET Core allows deployment on Linux, reducing Windows licensing costs and enabling modernization. Option E is correct because migrating the database to Amazon RDS for SQL Server reduces operational overhead by automating backups, patching, and management. Option A is incorrect because upgrading to Standard Edition on-premises does not reduce licensing costs or operational overhead. Option D is incorrect because containerizing a legacy .NET Framework 4.7 application with Docker on ECS Fargate is not straightforward due to Windows container limitations and does not address the database licensing costs.

Answer

Upgrade SQL Server to the Standard Edition on the current on-premises server before migrating

Answer

Containerize the application using Docker and deploy on Amazon ECS with AWS Fargate

Question 9

A company is migrating a web application to AWS. The application currently runs on a single server and uses a MySQL database. The company wants to ensure high availability and scalability. The web application is stateless. Which TWO actions should the company take to achieve these goals? (Choose TWO.)

Accepted Answer

Deploy the web application on Amazon EC2 instances in an Auto Scaling group across multiple Availability Zones, with an Application Load Balancer. To achieve high availability and scalability for the web application, the company should deploy the web tier across multiple Availability Zones using an Auto Scaling group with an Application Load Balancer (Option A), which distributes traffic and automatically scales instances. For the MySQL database, using Multi-AZ Amazon RDS (Option C) provides automatic failover and high availability. Option B (single RDS instance) is a single point of failure. Option D (ElastiCache) is for caching, not for high availability or scaling. Option E (large EC2 instance with Elastic IP) does not provide scalability or availability.

Answer

Use a single Amazon RDS for MySQL DB instance

Answer

Use Amazon ElastiCache to cache database queries

Answer

Use a large EC2 instance for the web application with Elastic IP

Question 10

Refer to the exhibit. A company is using AWS Migration Hub to track migrations. The above IAM policy is attached to an IAM role used by the migration tool. The migration tool reports that it cannot register the migration task with Migration Hub. Which action should the company add to the policy to fix the issue?

Accepted Answer

mgh:ImportMigrationTask. The migration tool needs mgh:ImportMigrationTask to register a migration task. Option B (AssociateDiscoveredResource) is for associating resource data, not registering tasks. Option C (CreateHomeRegion) is not needed. Option D (GetHomeRegion) is read-only.

Answer

mgh:AssociateDiscoveredResource

Answer

mgh:CreateHomeRegion

Answer

mgh:GetHomeRegion

Question 11

A company is migrating a critical 3-tier application to AWS. The application consists of a web tier, an application tier, and a PostgreSQL database. The web and application tiers are stateless and run on Linux. The company has deployed the web tier on EC2 instances behind an Application Load Balancer (ALB) across two Availability Zones. The application tier is deployed on EC2 instances in an Auto Scaling group across two Availability Zones. The PostgreSQL database is migrated to Amazon RDS for PostgreSQL with Multi-AZ deployment. The application uses sticky sessions (session affinity) to maintain user sessions on the web tier. After migration, users report that they are frequently logged out and lose session data. The web tier logs show that requests are being routed to different web instances. What is the MOST likely cause of this issue?

Accepted Answer

The target group for the web tier does not have sticky sessions (session affinity) enabled. The issue is that users are losing session data because requests are being routed to different web instances. Sticky sessions (session affinity) must be enabled on the target group of the ALB to ensure that all requests from a user's session are sent to the same web instance. Without sticky sessions, the ALB distributes requests across all healthy targets, causing session data to be lost if not shared. Option A is correct because the target group needs sticky sessions enabled. Option B (disable cross-zone load balancing) would not cause this issue; it would affect traffic distribution across AZs but not session persistence. Option C (idle timeout) would cause sessions to expire after a period of inactivity, not immediate logout. Option D (using NLB) is not necessary as ALB supports sticky sessions natively.

Answer

The ALB is configured to disable cross-zone load balancing, causing uneven traffic distribution

Answer

The idle timeout of the ALB is set too low, causing sessions to expire

Answer

The web tier should use a Network Load Balancer (NLB) instead of an ALB for sticky sessions

Question 12

A company is migrating a legacy application to AWS using the 7 Rs migration strategy. The application is a monolithic Java application running on a single on-premises server with a MySQL database. The company wants to reduce operational overhead and improve scalability. The development team has already containerized the application and tested it locally. The company wants to run the containerized application on AWS without managing the underlying infrastructure. Which AWS service should the company use to deploy the containerized application?

Accepted Answer

Amazon ECS with AWS Fargate launch type. Amazon ECS with AWS Fargate launch type is a serverless compute engine for containers, eliminating infrastructure management. Option B (EKS with managed node groups) still requires managing the node groups at the EC2 level. Option C (EC2 with Docker) requires managing EC2 instances. Option D (Lightsail containers) is not as scalable or integrated with AWS services as ECS with Fargate.

Answer

Amazon EKS with managed node groups

Answer

Amazon EC2 with Docker installed

Answer

Amazon Lightsail containers

Question 13

A company is migrating a legacy on-premises .NET application to AWS. The application uses a SQL Server database and requires full control over the operating system for compliance. Which migration strategy should the solutions architect recommend to minimize rework while meeting compliance requirements?

Accepted Answer

Rehost the application on EC2 instances and use RDS Custom for SQL Server.. Rehosting (lift-and-shift) with EC2 and RDS Custom for SQL Server allows the company to move the application and database with minimal changes while retaining OS-level control for compliance. RDS Custom provides OS access (SSH, patching) unlike standard RDS, meeting the compliance requirement. Option B (DynamoDB) would require significant application refactoring. Option C (RDS for SQL Server without Custom) lacks OS access. Option D (ECS with containers) adds containerization rework and does not inherently provide OS-level control.

Answer

Replace the database with Amazon DynamoDB and refactor the application.

Answer

Replatform the application to use RDS for SQL Server and deploy the application on EC2 instances.

Answer

Refactor the application to run on Amazon ECS using Docker containers.

Question 14

A company is migrating a large-scale Oracle data warehouse to Amazon Redshift. The migration must minimize downtime. The source database is 10 TB and runs on a single on-premises server with 1 Gbps network. Which approach should be used for the initial data load?

Accepted Answer

Use AWS Snowball Edge to transfer data to S3, then copy to Redshift.. Using AWS Snowball Edge devices for offline transfer avoids network bandwidth limitations and provides fast, secure transfer of large data volumes. Option A is wrong because 1 Gbps network would take over 22 hours and may cause congestion. Option B is wrong because DMS works for ongoing replication but initial load over network is slow. Option D is wrong because S3 Transfer Acceleration only speeds up S3 uploads, not the full pipeline.

Answer

Use AWS DMS to migrate data directly to Redshift over the network.

Answer

Use AWS DMS with ongoing replication after initial load via network.

Answer

Use S3 Transfer Acceleration to upload data to S3, then COPY to Redshift.

Question 15

A company is planning a hybrid cloud migration and needs to establish a dedicated network connection between its on-premises data center and AWS with consistent low latency. Which AWS service should be used?

Accepted Answer

AWS Direct Connect. AWS Direct Connect provides a dedicated private network connection from on-premises to AWS, offering consistent low latency. Option A is correct for this reason. Option B (AWS Client VPN) is incorrect because it is designed for individual remote clients, not a dedicated connection. Option C (AWS Transit Gateway) is incorrect as it is a hub for connecting networks, not a direct connection method. Option D (AWS Site-to-Site VPN) is incorrect because it uses the public internet and does not provide dedicated bandwidth or consistent low latency.

Answer

AWS Client VPN

Answer

AWS Transit Gateway

Answer

AWS Site-to-Site VPN
