SAP-C02 Accelerate Workload Migration and Modernization Practice Test 7 — 15 Questions

Question 1

A company is migrating a 10 TB SQL Server database to Amazon Aurora PostgreSQL. The migration must have minimal downtime. The source database is running on-premises with a 1 Gbps network link to AWS. Which strategy should be used to reduce the migration downtime?

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

Accepted Answer

Use AWS Database Migration Service (DMS) with full load and ongoing replication.. AWS Database Migration Service (DMS) is the correct choice because it combines a full load of the existing data with ongoing replication to capture incremental changes, minimizing downtime. Option A allows the target Aurora database to stay in sync with the source SQL Server until a cutover. Option B (backup/restore) requires significant downtime to take and restore the backup, and does not support ongoing replication. Option C (SCT) only converts the schema and exports data, missing the replication needed for minimal downtime. Option D is incorrect because an Aurora read replica can only be created from another Aurora DB instance, not from an on-premises database.

Answer

Take a full backup of the SQL Server database, upload it to Amazon S3, and restore to Aurora.

Answer

Use AWS Schema Conversion Tool (SCT) to convert the schema, then export data to flat files and upload to S3.

Answer

Create an Amazon Aurora read replica from the on-premises database.

Question 2

A company is migrating an on-premises Hadoop cluster to Amazon EMR. The cluster processes large datasets that are stored on HDFS. The company wants to minimize migration effort and cost. Which storage option should the company use with Amazon EMR?

Accepted Answer

Amazon S3 with EMRFS. Amazon S3 with EMRFS allows EMR to use S3 as a scalable, durable, and cost-effective storage layer, eliminating the need to manage HDFS. Option A is incorrect because EBS volumes require provisioning and management, and do not provide the same scalability and cost benefits. Option C is incorrect because Amazon FSx for HDFS is suitable for workloads requiring HDFS compatibility but is more complex and expensive than using S3. Option D is incorrect because Amazon EFS is a file system, not optimized for Hadoop workloads and typically used for shared file storage.

Answer

Amazon EBS volumes attached to the core nodes

Answer

Amazon FSx for HDFS

Answer

Amazon Elastic File System (EFS)

Question 3

A company is migrating a virtualized workload to AWS. The current environment uses VMware vSphere. The company wants to migrate the virtual machines (VMs) to AWS with minimal changes. Which AWS service should the company use?

Accepted Answer

AWS VM Import/Export. AWS VM Import/Export allows you to import virtual machine images from your VMware vSphere environment into Amazon EC2 as AMIs. This enables migration with minimal changes to the VMs. It supports various formats including VMDK, and you can use the AWS CLI or EC2 API to perform the import.

Answer

VMware Cloud on AWS

Answer

AWS Migration Hub

Answer

AWS Application Discovery Service

Question 4

A company is migrating a data warehouse from on-premises to Amazon Redshift. The source database is Teradata. The company needs to convert the schema and migrate historical data with minimal downtime. Which THREE services should the company use?

Accepted Answer

AWS Snowball Edge. AWS Schema Conversion Tool (SCT) (D) is correct because it converts the Teradata source schema and stored procedures into Amazon Redshift-compatible DDL, which is the required schema conversion step for this heterogeneous migration. AWS Database Migration Service (E) is correct because DMS performs the actual data migration from Teradata to Redshift, supports ongoing replication (CDC) to keep the target in sync, and thus enables minimal downtime during cutover. AWS Snowball Edge (A) is correct because for large historical data volumes, moving data physically via Snowball Edge avoids the slow and costly network transfer that would otherwise extend the migration window. AWS Data Pipeline (B) is not appropriate here since it is a workflow orchestration service, not a schema conversion or database replication tool. Amazon Kinesis Data Analytics (C) is for real-time stream processing with SQL, not for schema conversion or bulk/historical database migration.

Answer

AWS Data Pipeline

Answer

Amazon Kinesis Data Analytics

Question 5

A company is migrating an on-premises application to AWS and wants to implement a continuous integration/continuous delivery (CI/CD) pipeline. Which TWO AWS services should the company use to build the pipeline?

Accepted Answer

AWS CodePipeline. AWS CodePipeline (B) is correct because it is the fully managed CI/CD orchestration service that models, visualizes, and automates the release process through stages such as source, build, test, and deploy, making it the core service for building the pipeline. AWS CodeCommit (C) is correct because it is the fully managed Git-based source control service that serves as the source stage/repository for the application code feeding into the pipeline. AWS Cloud9 (A) is not correct because it is a cloud-based integrated development environment (IDE) for writing and debugging code, not a pipeline service. AWS CodeArtifact (D) is not correct because it is a managed artifact repository for storing and sharing software packages, not the pipeline itself. Amazon CodeGuru (E) is not correct because it is a machine learning-based developer tool for code reviews and application performance recommendations, not a CI/CD pipeline service.

Answer

AWS Cloud9

Answer

AWS CodeArtifact

Answer

Amazon CodeGuru

Question 6

A company is migrating data to Amazon S3 and requires that all objects uploaded to the bucket 'my-bucket' are encrypted with SSE-S3. The above IAM policy is attached to an IAM user. An application using the user's credentials attempts to upload an object without specifying the x-amz-server-side-encryption header. What will happen?

Accepted Answer

The upload fails because the Deny statement denies the request when encryption is not AES256.. The IAM policy includes a Deny statement that denies the upload if the x-amz-server-side-encryption header is not set to AES256. Since the application does not include this header, the Deny condition is triggered and the upload fails. Option A is incorrect because the Deny statement overrides the Allow statement when the condition is met. Option B is incorrect because the scenario only involves an IAM policy, not a bucket policy. Option D is incorrect because the absence of the encryption header means the Deny statement applies, so the upload does not proceed even though SSE-S3 is the default.

Answer

The upload succeeds because the Allow statement grants permission.

Answer

The upload fails because the bucket policy overrides the IAM policy.

Answer

The upload succeeds because the object is encrypted with the default SSE-S3.

Question 7

A company is deploying a web application using the above CloudFormation template. The template fails to create the Auto Scaling group. What is the most likely cause?

Accepted Answer

The LaunchConfiguration resource type is incorrect.. The most likely cause is that the LaunchConfiguration resource type is incorrect — in CloudFormation, the correct type is AWS::AutoScaling::LaunchConfiguration, and a typo or wrong type string causes the Auto Scaling group creation to fail because it cannot reference a valid launch configuration. The Auto Scaling group depends on the launch configuration, so an invalid type cascades into the ASG failure.

Answer

The instance type t2.micro is not supported in us-east-1.

Answer

The MinSize value must be less than the DesiredCapacity.

Answer

The AvailabilityZones list is invalid because it uses names instead of zone IDs.

Question 8

A company is migrating a .NET application from Windows Server to AWS. The application uses Microsoft SQL Server. The company wants to reduce licensing costs and minimize operational overhead. Which migration strategy should be recommended?

Accepted Answer

Replatform to Amazon RDS for PostgreSQL. (Replatform to Amazon RDS for PostgreSQL) is the best choice because it replaces SQL Server with PostgreSQL, which is open-source, thus eliminating SQL Server licensing costs. RDS also reduces operational overhead by managing the database. Option A (Replatform to Amazon RDS for SQL Server) reduces overhead but still incurs SQL Server licensing costs. Option B (Refactor to .NET Core on Amazon Linux) would require significant application changes and does not directly address database licensing. Option D (Rehost to Amazon EC2 with SQL Server on Windows) maintains high licensing costs and operational overhead.

Answer

Replatform to Amazon RDS for SQL Server

Answer

Refactor the application to .NET Core on Amazon Linux

Answer

Rehost to Amazon EC2 with SQL Server on Windows

Question 9

An organization wants to migrate 50 TB of data from an on-premises NAS to Amazon S3 over a slow internet connection. The migration must be completed within two weeks. Which approach is most appropriate?

Accepted Answer

Use AWS Snowball Edge. (AWS Snowball Edge) is correct because it can handle large data volumes over slow networks. Option A (AWS DataSync) may be too slow. Option C (Amazon S3 Transfer Acceleration) still uses internet. Option D (AWS Direct Connect) may take time to set up.

Answer

Use AWS DataSync over the internet

Answer

Use Amazon S3 Transfer Acceleration

Answer

Set up AWS Direct Connect

Question 10

A company is migrating a critical application to AWS and needs to ensure that the migration has minimal downtime. The application runs on a single on-premises server with a local MySQL database. Which strategy provides the lowest downtime?

Accepted Answer

Use AWS DMS with ongoing replication and cutover. (Use AWS DMS with ongoing replication and cutover) is correct because it enables continuous replication from the on-premises MySQL database to Amazon RDS, allowing a cutover with minimal downtime. Option A (Rehost using AWS Application Migration Service) typically involves some downtime during the replication and cutover. Option B (AWS Backup backup and restore to RDS) requires stopping the application to take a consistent backup, causing downtime. Option C (Stop, snapshot, restore) involves stopping the application, thus causing downtime.

Answer

Rehost the application using AWS Application Migration Service

Answer

Use AWS Backup to back up and restore to RDS

Answer

Stop the application, take a snapshot, and restore on EC2

Question 11

Question 12

A company is migrating a web application to AWS and wants to modernize it by using a microservices architecture. Which TWO AWS services should the company use to implement service discovery and API gateway functionality?

Accepted Answer

Amazon API Gateway. Amazon API Gateway (C) is correct because it provides a fully managed API gateway that handles REST, HTTP, and WebSocket APIs, offering request routing, throttling, authentication, and authorization for microservices fronting. AWS Cloud Map (E) is correct because it is the AWS service discovery solution that lets microservices register instances and discover each other by logical names via DNS or API calls, which is exactly the service discovery requirement. Amazon Route 53 (A) is a DNS service and can support basic service discovery patterns, but it is not the purpose-built service discovery mechanism for microservices that Cloud Map provides. AWS App Mesh (B) is a service mesh for traffic management, observability, and routing between services, not an API gateway or a service registry. Elastic Load Balancing (D) distributes traffic across targets but does not provide service discovery or API gateway capabilities such as request transformation, throttling, or API keys.

Answer

Amazon Route 53

Answer

AWS App Mesh

Answer

Elastic Load Balancing (ELB)

Question 13

A company is migrating a stateful application that uses local disks for caching to AWS. The application requires high-performance, low-latency storage that can be attached to a single EC2 instance. Which THREE AWS services or features should the company consider for the cache storage?

Accepted Answer

Amazon EBS io2 Block Express. Option A (Amazon EBS io2 Block Express) is correct because it delivers sub-millisecond latency and up to 256,000 IOPS with high durability, making it ideal for a high-performance cache volume attached to a single EC2 instance. Option C (Instance store) is correct because instance store volumes provide temporary, block-level storage physically attached to the host, offering very low latency and high throughput for cache data that can be regenerated. Option D (Local NVMe instance store) is correct because NVMe-based instance store volumes use PCIe-attached SSDs for the highest random I/O performance and lowest latency available on EC2, perfectly suited for a local cache. Option B (Amazon EFS) is not appropriate because it is a shared, network-based file system with higher latency and is not designed for single-instance, low-latency block caching. Option E (Amazon S3) is not appropriate because it is object storage accessed over the network, not attachable block storage, and cannot meet low-latency cache requirements.

Answer

Amazon EFS

Answer

Amazon S3

Question 14

A company is migrating a multi-tier web application to AWS. The application includes an Apache web server and a MySQL database. The operations team needs to scale the web tier based on CPU utilization while maintaining a static IP for the database. Which combination of AWS services should the solutions architect use?

Accepted Answer

Auto Scaling group for web tier with an Application Load Balancer; Amazon EC2 instance for MySQL database with an Elastic IP. An Application Load Balancer (ALB) is ideal for HTTP/HTTPS traffic and supports Auto Scaling groups for the web tier. For the database, an EC2 instance with an Elastic IP provides a static IP address, which is required. RDS does not support static Elastic IPs, so option B is correct.

Answer

Auto Scaling group for web tier with a Network Load Balancer; Amazon RDS for MySQL database with a static Elastic IP

Answer

Auto Scaling group for web tier with an Application Load Balancer; Amazon RDS for MySQL database with a static Elastic IP

Answer

Auto Scaling group for web tier with a Classic Load Balancer; Amazon EC2 instance for MySQL database with an Elastic IP

Question 15

A company plans to migrate 50 on-premises virtual machines (VMs) to AWS. The migration must be completed within 2 weeks. The VMs run various operating systems and have a total data size of 10 TB. The company has a low-bandwidth internet connection (50 Mbps). Which migration approach minimizes the time to transfer the data?

Accepted Answer

Use AWS Snowball Edge to transfer the VM images physically. AWS Snowball Edge is a petabyte-scale data transport solution that uses secure physical devices to transfer large amounts of data into and out of AWS. With a 50 Mbps internet connection, transferring 10 TB would take approximately 18.5 days (10 TB * 8 * 10^6 Mb / 50 Mbps / 86400 s ≈ 18.5 days), exceeding the 2-week deadline. Snowball Edge can transfer the data physically within days, making it the fastest option.

Answer

Set up an AWS Direct Connect connection to increase bandwidth

Answer

Create a VPN tunnel to AWS and use rsync to copy the data

Answer

Use AWS Application Migration Service to replicate the VMs continuously
