Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 39 discussion

trusted advisor doesn't have option to upload data, so option F is irrelavent

A vs B -> A because we need to use AWS Application Discovery and it provides its own agent https://docs.aws.amazon.com/application-discovery/latest/userguide/discovery-agent.html C vs D -> D because AWS Application Discovery is integrated with AWS Migration Hub and it can be used to group servers into applications https://aws.amazon.com/migration-hub/faqs/#:~:text=How%20do%20I%20group%20servers%20into%20an%20application%3F E vs. F -> E as AWS Migration Hub allows to generate recommendation for instance types https://docs.aws.amazon.com/migrationhub/latest/ug/ec2-recommendations.html

A. Assess the existing applications by installing AWS Application Discovery Agent on the physical machines and VMs. D. Group servers into applications for migration by using AWS Migration Hub. E. Generate recommended instance types and associated costs by using AWS Migration Hub.

Why not B ? B. Assess the existing applications by installing AWS Systems Manager Agent on the physical machines and VMs: Explanation: AWS Systems Manager Agent is used for managing and automating tasks on EC2 instances, not for capturing detailed application and performance data during an assessment phase. AWS Application Discovery Agent is more appropriate for this purpose.

ADE is correct

The correct answers are: * A. Assess the existing applications by installing AWS Application Discovery Agent on the physical machines and VMs. The AWS Application Discovery Service helps gather detailed information about on-premises data centers, including servers, network dependencies, and performance metrics. * D. Group servers into applications for migration by using AWS Migration Hub. AWS Migration Hub provides a centralized location to track the progress of application migrations across multiple AWS and partner solutions. It allows grouping discovered servers into applications, which simplifies the organization of migration tasks. * E. Generate recommended instance types and associated costs by using AWS Migration Hub. After servers are discovered and grouped into applications, AWS Migration Hub can analyze the collected data to recommend suitable Amazon EC2 instance types. This ensures that the migrated applications are hosted on the most cost-effective resources.

ADE no brainer

B in incorrect as System Manager doesn't do discovery however, SSM Agent makes it possible for Systems Manager to update, manage, and configure the resources in AWS as well as on-premises. ADE

ADE is correct answer.

B is incorrect because the servers are on prem.

ADE no doubts ✅

Logical answer : Falls under the domain "Accelerate Workload Migration and Modernization" promoting MigrationHub Step 1 - Identify the apps Step 2 - Group them Step 3 - Before hand, find out what instance types would need to be in when actual migration happens https://d1.awsstatic.com/Product-Page-Diagram_AWS-Migration-Hub-Orchestrator%402x.0c34c9483d13ebd26cf9072193384a58531624f3.png For OnPremises migrations, first phase is Discovery which can be done with Discovery agent , A https://d1.awsstatic.com/products/application-discovery-service/Product-Page-Diagram_AWS-Application-Discovery-Service%201.9d81c27f3de50349a9406b8def61b8eb914e2930.png I wont go with Trusted Advisor although it advises how cost can be advised because- This applies for already aws available environment. Here, about to get migrated into AWS and Architects need to discover lot of info before hand to plan alot. So I choose E between E and F. My answer - A,D,E

Why Option C Group servers into applications for migration by using AWS Systems Manager Application Manager is incorrect?

A is better than B. > Agent-based discovery can be performed by deploying the AWS Application Discovery Agent on each of your VMs and physical servers. The agent installer is available for Windows and Linux operating systems. It collects static configuration data, detailed time-series system-performance information, inbound and outbound network connections, and processes that are running. https://docs.aws.amazon.com/application-discovery/latest/userguide/what-is-appdiscovery.html

BDE. Trusted Advisor is not for onprem assessments. Migration hub does EC2 ones
