SAP-C02 Accelerate Workload Migration and Modernization Practice Test 8 — 15 Questions

Question 1

A company is migrating a critical application to AWS. The application must be highly available across two Availability Zones. The migration plan includes rehosting the application on EC2 instances in an Auto Scaling group behind an ALB. Which configuration ensures that the application remains available during an Availability Zone failure?

Accepted Answer

Use an Auto Scaling group with a minimum of 2 across two Availability Zones, with a distribution strategy of 'balanced best effort'. Option D is correct because spreading instances across two AZs with a minimum of one per AZ ensures that if one AZ fails, the other still has capacity. Option A is wrong because a single AZ does not provide AZ-level fault tolerance. Option B is wrong because a single instance per AZ with a minimum of 1 would allow scaling down to 0. Option C is wrong because placing all instances in one subnet is a single point of failure.

Answer

Use an Auto Scaling group with a minimum of 1 and maximum of 10 across two AZs

Answer

Launch instances in a single Availability Zone with multiple subnets

Answer

Launch instances in two Availability Zones but place all instances in the same subnet

Question 2

A company is migrating a legacy application that uses a network file system (NFS) for shared storage. The application runs on Windows servers. Which AWS storage service should be used for the migration?

Accepted Answer

Amazon FSx for Windows File Server. Option B is correct because Amazon FSx for Windows File Server provides native SMB support for Windows. Option A is wrong because EFS is POSIX-based, not fully compatible with Windows. Option C is wrong because S3 is object storage, not a file system. Option D is wrong because EBS volumes cannot be shared across multiple instances easily.

Answer

Amazon EFS

Answer

Amazon EBS

Answer

Amazon S3

Question 3

A company is migrating a large-scale batch processing workload to AWS. The workload runs on a schedule and processes terabytes of data. The migration must be cost-effective. Which AWS service is best suited for this workload?

Accepted Answer

AWS Batch. Option C is correct because AWS Batch is designed for batch computing and can automatically provision the optimal quantity and type of compute resources. Option A is wrong because Lambda has a 15-minute timeout and limited memory. Option B is wrong because EMR is optimized for big data frameworks like Spark, not general batch. Option D is wrong because EC2 requires manual management of instances.

Answer

Amazon EMR

Answer

AWS Lambda

Answer

Amazon EC2 with Auto Scaling

Question 4

A company is migrating a legacy application that uses a third-party identity provider (IdP) for authentication. The application currently uses SAML 2.0. The company wants to use AWS IAM Identity Center for centralized access management. What is the best approach to integrate the IdP with AWS?

Accepted Answer

Configure IAM Identity Center to use the existing IdP as the identity source via SAML 2.0 federation. Option A is correct because AWS IAM Identity Center supports SAML 2.0 federation with external IdPs. Option B is wrong because creating IAM users duplicates identities. Option C is wrong because Cognito is for customer-facing apps, not corporate SSO. Option D is wrong because Directory Service is for Active Directory, not generic SAML.

Answer

Use AWS Directory Service for Microsoft Active Directory to synchronize with the IdP

Answer

Create IAM users for each employee and assign groups and permissions

Answer

Use Amazon Cognito user pools with the IdP as a SAML identity provider

Question 5

A company is migrating a stateful application to AWS. The application maintains session state in memory on the application server. Which AWS service should be used to store session state for high availability?

Accepted Answer

Amazon ElastiCache. Option B is correct because ElastiCache is an in-memory data store ideal for session state. Option A is wrong because RDS is relational database, slower for session state. Option C is wrong because S3 is object storage, not suitable for low-latency session state. Option D is wrong because EBS is block storage attached to a single instance.

Answer

Amazon RDS

Answer

Amazon S3

Answer

Amazon EBS

Question 6

A company is migrating a multi-tier web application to AWS. The application uses a commercial database that requires a license. The company wants to reduce licensing costs. Which migration strategy should be considered?

Accepted Answer

Replatform the database to Amazon RDS for an open-source engine like PostgreSQL. Option C is correct because replatforming to Amazon RDS for an open-source engine eliminates commercial license costs. Option A is wrong because rehosting to EC2 still requires the same license. Option B is wrong because refactoring to use a different database may involve significant rework. Option D is wrong because repurchasing to SaaS may not be suitable.

Answer

Rehost the database to EC2 with the same database software

Answer

Repurchase a Software as a Service (SaaS) alternative

Answer

Refactor the application to use Amazon DynamoDB

Question 7

A company is migrating a legacy application to Amazon ECS. The application has a stateful component that stores data on the local filesystem. Which TWO storage options can be used to persist data beyond the lifecycle of the container?

Accepted Answer

Amazon EBS. Options B and D are correct. EFS provides persistent shared file storage, and EBS volumes can be attached to EC2 instances running ECS tasks. Option A is wrong because Fargate ephemeral storage is not persistent. Option C is wrong because S3 is object storage, not a file system. Option E is wrong because ECR is a container registry.

Answer

Amazon ECS Fargate ephemeral storage

Answer

Amazon ECR

Answer

Amazon S3

Question 8

A company is migrating a large number of on-premises VMs to AWS. They need to assess the current environment and track migration progress. Which THREE AWS services should be used together?

Accepted Answer

AWS Application Migration Service (MGN). Options A, C, and D are correct. AWS Application Discovery Service discovers on-premises servers. AWS Migration Hub tracks migration progress across multiple tools. AWS Application Migration Service (MGN) automates the migration of VMs. Option B is wrong because Server Migration Service (SMS) is deprecated. Option E is wrong because DMS is for database migration, not VMs.

Answer

AWS Server Migration Service (SMS)

Answer

AWS Database Migration Service (DMS)

Question 9

A company is planning to migrate a workload to AWS and needs to estimate the total cost of ownership (TCO) compared to on-premises. Which TWO AWS tools can be used to perform this analysis?

Accepted Answer

AWS Pricing Calculator. Options A and C are correct. AWS Pricing Calculator estimates costs of AWS services. AWS TCO Calculator compares on-premise costs to AWS. Option B is wrong because AWS Budgets tracks spending. Option D is wrong because AWS Cost Explorer analyzes existing AWS spending. Option E is wrong because AWS Organizations manages accounts.

Answer

AWS Organizations

Answer

AWS Cost Explorer

Answer

AWS Budgets

Question 10

Refer to the exhibit. An IAM policy is attached to an IAM user. The user tries to upload an object to `s3://my-bucket/secret/data.txt` from an IP address in the 10.0.0.0/8 range. What will happen?

Accepted Answer

The upload fails because the Deny statement explicitly denies s3:PutObject for the prefix secret/ from the specified IP range.. Option B is correct. The Deny statement explicitly denies s3:PutObject (part of s3:*) for the prefix secret/ when the source IP is in 10.0.0.0/8. Since the condition matches, the Deny overrides the Allow. Option A is wrong because the Deny applies. Option C is wrong because the Deny is conditional, not unconditional. Option D is wrong because there is no explicit Deny for other IPs, but the condition applies to the user's IP.

Answer

The upload succeeds because the Allow statement grants s3:PutObject.

Answer

The upload succeeds because the Deny statement only applies to GetObject, not PutObject.

Answer

The upload fails because the Deny statement denies all s3 actions unconditionally.

Question 11

Refer to the exhibit. A solutions architect runs the CLI command to list EC2 instances. The output shows three instances. The architect wants to start the stopped instance and ensure it retains its instance store data. What should the architect do?

Accepted Answer

Create an AMI from the stopped instance before starting it, then launch a new instance from the AMI.. Option B is correct. Instance store volumes are ephemeral and data is lost when the instance is stopped. To retain data, the architect must move the data to an EBS volume or another persistent store. Option A is wrong because starting the instance will not recover instance store data. Option C is wrong because instance store volumes cannot be detached. Option D is wrong because changing the instance type does not affect instance store persistence.

Answer

Modify the instance type to one that supports instance store, then start the instance.

Answer

Detach the instance store volume and attach it to a running instance.

Answer

Run `aws ec2 start-instances --instance-ids i-0a1b2c3d4e5f6g7h9` to start the instance.

Question 12

Refer to the exhibit. A company deploys this CloudFormation template. After deployment, they enable S3 Transfer Acceleration on the bucket. Later, they update the stack. What happens to the Transfer Acceleration setting?

Accepted Answer

The Transfer Acceleration setting remains unchanged after the update.. Option D is correct. CloudFormation drift detection does not automatically revert manual changes. The Transfer Acceleration setting is a property of the bucket; if not defined in the template, CloudFormation may not manage it, but typically manual changes are not overwritten unless the template explicitly defines them. However, best practice is to define all settings in the template to avoid drift. Option A is wrong because CloudFormation does not automatically disable it. Option B is wrong because CloudFormation does not automatically enable it. Option C is wrong because updates do not reset to default.

Answer

CloudFormation enables Transfer Acceleration because it is a best practice.

Answer

The update fails because of a conflict between the template and the manual change.

Answer

CloudFormation removes the Transfer Acceleration setting because it is not defined in the template.

Question 13

A company is migrating a legacy on-premises application to AWS. The application requires a relational database with Oracle compatibility and the ability to run read replicas across multiple Availability Zones. Which AWS service should the company use to minimize migration effort?

Accepted Answer

Amazon RDS for Oracle. Option C is correct because Amazon RDS for Oracle provides managed Oracle database with read replicas across AZs. Option A is wrong because DynamoDB is NoSQL, not relational. Option B is wrong because RDS for MySQL does not support Oracle compatibility. Option D is wrong because EC2 with self-managed Oracle requires more operational overhead.

Answer

Amazon RDS for MySQL

Answer

Amazon EC2 with self-managed Oracle

Answer

Amazon DynamoDB

Question 14

A company is migrating a monolithic application to microservices on AWS. The application uses a shared MySQL database. The team wants to decouple the database per microservice. Which strategy should the team use to minimize downtime during migration?

Accepted Answer

Use the strangler fig pattern to gradually migrate functionality to microservices, each with its own database.. Option B is correct because the strangler fig pattern incrementally replaces parts of the monolith. Option A is wrong because re-platforming as-is does not decouple the database. Option C is wrong because a single shared database contradicts microservices. Option D is wrong because rewriting the entire application at once increases risk and downtime.

Answer

Rehost the application on EC2 and use a single RDS MySQL instance for all microservices.

Answer

Use AWS Database Migration Service (DMS) to replicate the shared database to multiple target databases in real time.

Answer

Rewrite the entire application as microservices in a single release, using a shared database initially.

Question 15

A company wants to migrate 500 TB of data from an on-premises data center to Amazon S3. The company has a 1 Gbps dedicated network connection to AWS. What is the most cost-effective and time-efficient migration method?

Accepted Answer

Use AWS Snowball Edge to physically ship the data to AWS.. Option D is correct because AWS Snowball Edge provides physical storage for large data transfers, avoiding long transfer times over a 1 Gbps link. Option A is wrong because S3 Transfer Acceleration improves speed but still uses the network. Option B is wrong because AWS DataSync is designed for smaller, ongoing transfers. Option C is wrong because Direct Connect alone does not transfer data; you still need to copy over the connection.

Answer

Use S3 Transfer Acceleration to upload data over the existing internet connection.

Answer

Use AWS DataSync to transfer data over the dedicated network.

Answer

Establish an AWS Direct Connect connection and use S3 multipart upload.
