SAP-C02 Accelerate Workload Migration and Modernization Practice Test 23 — 15 Questions

Question 1

A company is migrating a critical application to AWS. The migration plan includes a pilot light strategy. The company has set up a small replica of the environment in AWS. During a disaster, the company wants to quickly provision the full production environment. Which AWS service is best suited for this purpose?

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

Accepted Answer

AWS CloudFormation. AWS CloudFormation is the best service for this scenario because it allows you to define the entire infrastructure as code in templates, which can be stored and then quickly executed to provision the full production environment during a disaster. This aligns with the pilot light strategy, where a small replica is already running and CloudFormation can rapidly scale it up. Option A (OpsWorks) is wrong because it is configuration management service for Chef/Puppet, not for quickly provisioning full environments. Option B (Elastic Beanstalk) is wrong because it is designed for deploying web applications, not for provisioning custom infrastructure. Option D (CodeDeploy) is wrong because it handles application deployments, not infrastructure provisioning.

Answer

AWS OpsWorks

Answer

AWS Elastic Beanstalk

Answer

AWS CodeDeploy

Accepted Answer

Rehost using AWS Application Migration Service (MGN) and Amazon EC2.. Rehosting (lift-and-shift) using AWS Application Migration Service (MGN) and EC2 meets the no-code-change requirement and can be completed within 3 months. Option A is wrong because retaining the application on-premises does not migrate it to AWS, failing the migration goal. Option C is wrong because replatforming to Amazon RDS would likely require code changes (e.g., database drivers, queries), violating the no-code-change constraint. Option D is wrong because refactoring into microservices requires significant code changes and is too time-consuming for the 3-month timeline.

Answer

Retain the application on-premises and use AWS Storage Gateway for backup.

Answer

Replatform to use Amazon RDS for MySQL.

Answer

Refactor into microservices on Amazon ECS.

Question 3

A company wants to migrate a legacy Oracle database to AWS with minimal downtime. The database is 2 TB in size and runs on a single on-premises server. The company requires the ability to cut over quickly and roll back if needed. Which AWS service should be used?

Accepted Answer

AWS Database Migration Service (DMS) with ongoing replication from the source to an Amazon RDS for Oracle target.. AWS Database Migration Service (DMS) with ongoing replication enables continuous data replication from the on-premises Oracle database to Amazon RDS for Oracle, allowing minimal downtime during cutover. It also supports rollback by stopping replication and reverting to the source. Option A is incorrect because S3 Transfer Acceleration is for fast uploads to S3, not for database migration with replication. Option C is incorrect because AWS Schema Conversion Tool (SCT) handles schema conversion, not ongoing data replication. Option D is incorrect because AWS Snowball Edge is an offline data transfer device, which does not meet the minimal downtime requirement.

Answer

Use S3 Transfer Acceleration to upload the database dump directly to an EC2 instance.

Answer

AWS Schema Conversion Tool (SCT) to convert the schema and then export the data to flat files for import.

Answer

AWS Snowball Edge to copy the database files and then restore on Amazon RDS.

Question 4

A company is migrating a legacy application to AWS using the rehost (lift-and-shift) strategy. The application uses a proprietary database that is not supported by Amazon RDS. The company wants to automate the migration of multiple servers and minimize downtime. Which AWS service should be used to automate the server migration?

Accepted Answer

AWS Application Migration Service (AWS MGN).. AWS Application Migration Service (MGN) automates lift-and-shift with minimal downtime. Option A is wrong because AWS CloudFormation is for infrastructure provisioning, not migration. Option C is wrong because AWS Server Migration Service (SMS) is older and less automated compared to MGN. Option D is wrong because AWS Database Migration Service (DMS) is for databases, not servers.

Answer

AWS CloudFormation to recreate the server configuration.

Answer

AWS Server Migration Service (SMS).

Answer

AWS Database Migration Service (AWS DMS) for the database and manual server migration.

Question 5

A company is migrating a stateful application to AWS. The application uses sticky sessions (session affinity) on the current on-premises load balancer. The company wants to use an Application Load Balancer (ALB) in AWS. Which feature should be enabled?

Accepted Answer

Sticky sessions (session affinity) using a cookie generated by the load balancer.. ALB supports sticky sessions via a load balancer-generated cookie (AWSALB) that binds a client to a specific target for the duration of the stickiness policy. Enabling stickiness on the target group preserves session state for stateful applications migrated from on-premises load balancers that used session affinity. This is the direct ALB feature that replicates the on-premises behavior.

Answer

Connection draining (deregistration delay).

Answer

Health checks to ensure only healthy instances receive traffic.

Answer

Cross-zone load balancing.

Question 6

A company is migrating a critical application to AWS. The migration plan includes a pilot light strategy. The company has set up a small replica of the environment in AWS. During a disaster, the company wants to quickly provision the full production environment. Which AWS service is best suited for this purpose?

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

Accepted Answer

Deploy the web tier across multiple Availability Zones.. Option B is correct because deploying the web tier across multiple Availability Zones ensures that if one AZ fails, the application remains available through instances in another AZ, which is a fundamental high-availability design for a rehosted web tier on EC2. Option C is correct because Amazon RDS Multi-AZ maintains a synchronous standby replica in a different AZ and automatically fails over the database endpoint during an AZ outage or primary failure, providing high availability for the database tier. Option A is not appropriate because EC2 Auto Scaling operates within a single Region across AZs; it cannot launch instances across multiple AWS Regions, and cross-Region scaling is not a standard Auto Scaling capability. Option D is not the best fit because read replicas are primarily for scaling read-heavy workloads and are asynchronous, so they do not provide automatic failover for high availability. Option E is incorrect because confining the database to a single AZ creates a single point of failure and undermines the disaster recovery and high availability goals.

Answer

Configure Amazon EC2 Auto Scaling to launch instances across multiple AWS Regions.

Answer

Use Amazon RDS read replicas to offload read traffic.

Answer

Use a single Availability Zone for the database to reduce latency.

Question 7

A company is migrating a legacy Oracle database to Amazon Aurora PostgreSQL. The migration must minimize downtime and support ongoing replication. Which AWS service should the company use?

Accepted Answer

AWS Database Migration Service (DMS) with change data capture (CDC). B is correct because AWS DMS with ongoing replication (CDC) can migrate data with minimal downtime. A is wrong because AWS DataSync is designed for file-based data transfers, not database replication. C is wrong because AWS Direct Connect provides a dedicated network connection but does not handle database migration or replication. D is wrong because the AWS Schema Conversion Tool (SCT) only converts schema and code, not the actual data.

Answer

AWS DataSync

Answer

AWS Direct Connect

Answer

AWS Schema Conversion Tool (SCT)

Question 8

A company is using AWS Application Migration Service (MGN) to migrate hundreds of on-premises servers to AWS. After the migration, some servers fail a health check. What is the most efficient way to remediate the failed servers?

Accepted Answer

Launch test instances from MGN, diagnose the issues, then update the source servers and perform a final cutover.. It follows the recommended MGN workflow for remediation: launch test instances to identify issues, fix them on the source server, and then perform a final cutover. Option B is inefficient as it restarts the entire replication and cutover process without testing. Option C is incorrect because restoring from a backup AMI is not part of the MGN migration process and does not allow iterative fixes. Option D is wrong because CloudEndure Migration is the former name of MGN and is not a separate service for re-migration.

Answer

Rerun the MGN replication and perform a new cutover.

Answer

Restore the servers from the latest AMI and re-run the health check.

Answer

Use AWS CloudEndure Migration to re-migrate the servers.

Question 9

A company is migrating a critical application to AWS. The migration plan includes a pilot light strategy. The company has set up a small replica of the environment in AWS. During a disaster, the company wants to quickly provision the full production environment. Which AWS service is best suited for this purpose?

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

Accepted Answer

Establish an AWS Direct Connect connection between the on-premises data center and AWS.. AWS Direct Connect provides a dedicated private network connection from on-premises to AWS, offering consistent low latency and high bandwidth compared to internet-based connections. For a lift-and-shift application requiring consistent low-latency access to an on-premises database, Direct Connect is the appropriate solution.

Answer

Set up a site-to-site VPN over the internet.

Answer

Create a VPC peering connection between the on-premises network and AWS VPC.

Answer

Use AWS Client VPN to connect from the application servers.

Question 10

A company is modernizing a legacy application by breaking it into microservices. The application has a complex set of dependencies and requires gradual migration. Which design pattern should the company use?

Accepted Answer

Strangler Fig pattern. (Strangler Fig pattern) because it allows incremental replacement of legacy system functionality with microservices, enabling gradual migration despite complex dependencies. Option A (Blue/Green deployment) is a deployment strategy, not a migration pattern. Option B (Saga pattern) is for managing distributed transactions, not incremental replacement. Option D (Circuit Breaker) is a fault-tolerance pattern.

Answer

Blue/Green deployment pattern

Answer

Saga pattern

Answer

Circuit Breaker pattern

Question 11

A company is migrating a large-scale Hadoop cluster to Amazon EMR. The migration plan includes moving data from HDFS to Amazon S3. The company wants to minimize costs and ensure data durability. Which approach should the company use?

Accepted Answer

Use Apache DistCp to copy data from HDFS to S3.. B is correct because DistCp is designed for efficient HDFS-to-S3 transfers, and S3's 99.999999999% durability meets requirements. A is wrong because VPN and rsync are not optimized for large-scale data transfer to S3. C is wrong because Snowball Edge adds latency and is not necessary for data already in the cluster. D is wrong because AWS DMS is for databases, not file systems.

Answer

Set up a VPN connection and use rsync to copy data to S3.

Answer

Use AWS Snowball Edge to physically transfer data from the cluster.

Answer

Use AWS Database Migration Service (DMS) to migrate the data to S3.

Question 12

A company is migrating a legacy Windows application to AWS. The application requires a shared file system accessible from multiple EC2 instances. Which AWS storage solution should the company use?

Accepted Answer

Amazon FSx for Windows File Server. Amazon FSx for Windows File Server provides a fully managed native Windows file system that supports the SMB protocol, which is required for legacy Windows applications to access shared file systems. Amazon EFS uses NFS, which is not natively supported by Windows. EBS with multi-attach is limited to a small number of instances and not ideal for file sharing. S3 is object storage and does not provide a traditional file system interface.

Answer

Amazon Elastic File System (EFS)

Answer

Amazon Elastic Block Store (EBS) with multi-attach enabled

Answer

Amazon Simple Storage Service (S3)

Question 13

A company is migrating a legacy application to AWS and wants to use a containerized architecture. The application requires persistent storage that can be shared across multiple containers in an Amazon ECS cluster. Which TWO storage solutions should the company consider? (Choose TWO.)

Accepted Answer

Amazon Elastic File System (EFS). Amazon EFS (B) is correct because it is a fully managed, elastic NFS file system that can be mounted simultaneously by multiple EC2 instances and ECS tasks across Availability Zones, providing the shared persistent storage the application needs. Amazon FSx for Lustre (C) is also correct because it is a high-performance, POSIX-compliant shared file system designed for compute-intensive workloads, and it can be mounted concurrently by many containers in an ECS cluster. Amazon S3 (A) is object storage accessed via HTTP APIs rather than a mountable shared file system, so it does not natively provide the shared persistent volume semantics required. Amazon EBS (D) provides block storage that attaches to a single EC2 instance at a time and cannot be shared across multiple containers or hosts. Amazon RDS (E) is a managed relational database service, not a general-purpose shared storage layer for container file systems.

Answer

Amazon Simple Storage Service (S3)

Answer

Amazon Elastic Block Store (EBS)

Answer

Amazon Relational Database Service (RDS)

Question 14

A company is migrating a legacy application to AWS. The application uses a custom authentication mechanism that relies on LDAP. The company wants to minimize changes to the application. Which THREE services should the company consider for integrating LDAP authentication? (Choose THREE.)

Accepted Answer

AWS Directory Service Simple AD. Options A, B, and C are correct because all three are AWS Directory Service offerings that expose LDAP endpoints the legacy application can bind to with minimal code changes. Simple AD (A) is a Samba 4-based, Microsoft AD-compatible directory that supports LDAP and Kerberos, so an app using LDAP authentication can point at it directly. AD Connector (B) is a proxy that forwards LDAP (and Kerberos) authentication requests to an existing on-premises Active Directory, letting the app keep using LDAP while credentials stay on-premises. AWS Directory Service for Microsoft Active Directory (C), i.e., AWS Managed Microsoft AD, runs actual Windows AD domain controllers that serve LDAP/LDAPS, so it natively satisfies LDAP-dependent authentication. Option D (Amazon Cognito user pools) is wrong because it is an OIDC/OAuth 2.0 identity provider for web/mobile apps, not an LDAP directory, and would require rewriting the app's authentication logic. Option E (IAM) is wrong because IAM handles AWS API authorization via SigV4 and federation (SAML/OIDC), not LDAP bind authentication for an application.

Answer

Amazon Cognito user pools

Answer

AWS Identity and Access Management (IAM)

Question 15

A company is migrating a monolithic application to AWS. The application consists of a web server, an application server, and a MySQL database. The web server and application server run on the same EC2 instance. The company wants to minimize changes during migration. Which migration strategy should the architect recommend?

Accepted Answer

Rehost using AWS Application Migration Service (AWS MGN). Rehosting using AWS Application Migration Service (AWS MGN) is the correct strategy because it minimizes changes by lifting and shifting the existing servers to EC2. The application remains monolithic, and the database can stay on the same instance or be moved as-is. This aligns with the requirement to minimize changes during migration.

Answer

Refactor the application into microservices on Amazon ECS

Answer

Replatform by migrating the database to Amazon RDS

Answer

Retire the application and replace it with a SaaS solution
