AWS Certified Solutions Architect – Professional (SAP-C02) — Question 295

A company is planning to migrate several applications to AWS. The company does not have a good understanding of its entire application estate. The estate consists of a mixture of physical machines and VMs.

One application that the company will migrate has many dependencies that are sensitive to latency. The company is unsure what all the dependencies are. However the company knows that the low-latency communications use a custom IP-based protocol that runs on port 1000. The company wants to migrate the application and these dependencies together to move all the low-latency interfaces to AWS at the same time.

The company has installed the AWS Application Discovery Agent and has been collecting data for several months.

What should the company do to identify the dependencies that need to be migrated in the same phase as the application?

Answer options

• A. Use AWS Migration Hub and select the servers that host the application. Visualize the network graph to find servers that interact with the application. Turn on data exploration in Amazon Athena. Query the data that is transferred between the servers to identify the servers that communicate on port 1000. Return to Migration Hub. Create a move group that is based on the findings from the Athena queries.
• B. Use AWS Application Migration Service and select the servers that host the application. Visualize the network graph to find servers that interact with the application. Configure Application Migration Service to launch test instances for all the servers that interact with the application. Perform acceptance tests on the test instances. If no issues are identified, create a move group that is based on the tested servers.
• C. Use AWS Migration Hub and select the servers that host the application. Turn on data exploration in Network Access Analyzer. Use the Network Access Analyzer console to select the servers that host the application. Select a Network Access Scope of port 1000 and note the matching servers. Return to Migration Hub. Create a move group that is based on the findings from Network Access Analyzer.
• D. Use AWS Migration Hub and select the servers that host the application. Push the Amazon CloudWalch agent to the identified servers by using the AWS Application Discovery Agent. Export the CloudWatch logs that the agents collect to Amazon S3. Use Amazon Athena to query the logs to find servers that communicate on port 1000. Return to Migration Hub Create a move group that is based on the findings from the Athena queries.

Correct answer: A

Explanation

AWS Application Discovery Agent collects system and network dependency data, which can be analyzed by enabling data exploration in AWS Migration Hub to store the data in Amazon S3 and query it with Amazon Athena. Querying this dataset allows the user to filter for port 1000 traffic to identify the exact dependent servers, which can then be grouped into a move group in Migration Hub. Other options are incorrect because Network Access Analyzer is for VPC network analysis, CloudWatch agents are not deployed via Discovery Agent for this purpose, and Application Migration Service is for replication rather than discovery analysis.
