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

Question 1

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. Option B is correct: Rehost (lift-and-shift) moves the application as-is to EC2 with MySQL. Option A (Refactor) requires code changes. Option C (Replatform) changes the database to RDS, which may require code changes. Option D (Retire) is not appropriate.

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 2

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. Option C is correct: Using AWS Global Accelerator provides static anycast IP addresses and directs traffic to the ALB. Option A (NLB) would require a separate NLB, adding complexity. Option B (Elastic IP on ALB) is not possible. Option D (Route 53) does not provide static IP addresses for whitelisting.

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 3

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.. Option B is correct: Multi-AZ RDS provides automatic failover, and ALB distributes traffic to web/app servers across AZs. Option A (EC2 + Elastic IPs) requires manual failover. Option C (single AZ) is not highly available. Option D (Route 53 latency) adds complexity and latency.

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 4

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. Options A and D are correct. AWS MGN requires outbound internet access or VPC endpoints to communicate with the service endpoint. Option B (enable inbound rules) is for incoming traffic, not needed. Option C (change instance type) is unrelated. Option E (reinstall agent) is not the first troubleshooting step.

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 5

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. Options A, C, and D are correct. Rehosting on EC2 with SQL Server Web Edition reduces licensing costs (A). Rebuilding on .NET Core allows cross-platform deployment on Linux (C). Using RDS for SQL Server reduces operational overhead for database management (D). Option B (AWS Fargate) is not suitable for .NET Framework. Option E (SQL Server Standard) does not reduce 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 6

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. Options B and D are correct. Deploying the web tier across multiple AZs with Auto Scaling and an ALB provides high availability and scalability (B). Using Multi-AZ RDS provides database failover (D). Option A (single RDS instance) is not highly available. Option C (single EC2 instance) is a single point of failure. Option E (ElastiCache) is not required for 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 7

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

Answer

mgh:AssociateDiscoveredResource

Answer

mgh:CreateHomeRegion

Answer

mgh:GetHomeRegion

Question 8

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. Option B is correct: Sticky sessions must be enabled on the ALB target group to ensure requests from a user are sent to the same web instance. Option A (increased timeouts) might help but is not the root cause. Option C (disable cross-zone load balancing) would not solve session affinity across AZs. Option D (switch to NLB) is not necessary and NLB does not support HTTP features.

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 9

A company is migrating a large on-premises Oracle database to Amazon RDS for Oracle. The database is 2 TB in size and has a 24/7 uptime requirement. The company plans to use AWS Database Migration Service (AWS DMS) for continuous replication with minimal downtime. The source database is Oracle 11g running on Linux. During the full load phase, AWS DMS reports high latency and the replication slows down significantly. The source database CPU utilization is at 100% during the migration. The company needs to minimize the impact on production workload. What should the company do to improve the migration performance and reduce impact on the source database?

Accepted Answer

Set up an Oracle read replica and use it as the source for AWS DMS. Option D is correct: Using a read replica as the source for DMS offloads the load from the primary database. Option A (increase DMS instance size) may not help if the source is bottlenecked. Option B (reduce parallel load threads) would slow down migration. Option C (use change data capture only) still requires initial load.

Answer

Use AWS DMS change data capture (CDC) only, without full load, to reduce the load

Answer

Increase the size of the DMS replication instance to handle more load

Answer

Reduce the number of parallel load threads in the DMS task to decrease source CPU usage

Question 10

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. Option C is correct: AWS Fargate is a serverless compute engine for containers, eliminating infrastructure management. Option A (EC2) requires managing instances. Option B (EKS) requires managing the control plane. Option D (Lightsail) is not container-native.

Answer

Amazon EKS with managed node groups

Answer

Amazon EC2 with Docker installed

Answer

Amazon Lightsail containers

Question 11

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. Option A is wrong because RDS does not provide OS access. Option B is wrong because ECS requires containerization which adds rework. Option D is wrong because DynamoDB is NoSQL and would require significant application changes.

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 12

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 13

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 wrong because Site-to-Site VPN uses the public internet. Option B is wrong because Client VPN is for individual clients. Option D is wrong because Transit Gateway is a hub for connecting networks, not a direct connection method.

Answer

AWS Client VPN

Answer

AWS Transit Gateway

Answer

AWS Site-to-Site VPN

Question 14

A company is migrating a legacy application to AWS. The application has hardcoded IP addresses and uses non-HTTP protocols. The solutions architect needs to minimize changes to the application code. Which migration pattern should be used?

Accepted Answer

Rehost the application on EC2 instances with the same IP addresses using Elastic IPs.. Rehosting (lift-and-shift) with private IP addresses on EC2 and security groups allows the application to retain its IP configurations with minimal changes. Option A is wrong because refactoring to use DNS requires code changes. Option B is wrong because containerization requires code modifications. Option D is wrong because AWS Global Accelerator is for traffic management, not for replacing hardcoded IPs without code changes.

Answer

Use AWS Global Accelerator to assign static IP addresses.

Answer

Containerize the application and use service discovery.

Answer

Refactor the application to use DNS names instead of IP addresses.

Question 15

A company is migrating a stateful application that maintains session state in memory on a single server. The migration target is a highly available architecture on AWS. Which design should be used to preserve session state without modifying the application?

Accepted Answer

Use an Application Load Balancer with sticky sessions.. Using an Application Load Balancer with sticky sessions (session affinity) ensures that requests from a user are sent to the same target, preserving in-memory session state without code changes. Option A is wrong because ElastiCache would require application code to store/retrieve sessions. Option B is wrong because DynamoDB similarly requires code changes. Option D is wrong because Network Load Balancer does not support sticky sessions.

Answer

Use Amazon DynamoDB to store session state.

Answer

Use a Network Load Balancer with cross-zone load balancing.

Answer

Use Amazon ElastiCache to store session state externally.
