A global hospitality and reservation booking platform is planning to migrate its core reservation portal and loyalty program database to AWS. The current on-premises environment comprises:
- $150$ VMware vSphere virtual machines (VMs) running supported Windows Server and Red Hat Enterprise Linux (RHEL) operating systems.
- $10$ physical bare-metal servers running RHEL 7 that host production Oracle databases.
- The company's compliance policies strictly prohibit the installation of third-party software agents on the database servers.
- The outbound network policy blocks direct internet access from all on-premises servers. All outbound traffic must be routed through a centralized forward HTTP proxy.
- To perform right-sizing and design migration groupings, the solutions architect must collect CPU and memory utilization, disk I/O metrics, and detailed network dependency mappings (inbound and outbound connections) for both VMs and physical servers.

Which combination of actions should the solutions architect take to gather the discovery data and track the migration in AWS Migration Hub? (Choose two.)

Install the AWS Application Discovery Agent on the VMware VMs and configure the agents to route traffic through the outbound HTTP proxy.Answer
Use the AWS Migration Hub import template to manually import the database server configurations and performance metrics, then group them with the discovered VMs in AWS Migration Hub.Answer
C
Deploy the AWS Application Discovery Agentless Collector in the VMware environment to gather the network dependency mappings and performance metrics for the VMs.
D
Install the AWS Application Migration Service (MGN) replication agent on both the VMs and database servers to automatically map network dependencies using TCP port $1500$ .
E
Install the AWS Application Discovery Agent on the database servers and configure the outbound HTTP proxy to perform SSL decryption to validate the discovery payload.

Answer

Install the AWS Application Discovery Agent on the VMware VMs with proxy configuration, and manually import the database server configurations using the AWS Migration Hub import template.

The correct options involve installing the AWS Application Discovery Agent on the VMware VMs, which is necessary to gather the required network dependency mappings, and configuring the agent to use the forward HTTP proxy. For the database servers, since agents are prohibited and the servers are physical, importing their configuration via the CSV template is the only supported way to include them in the Migration Hub tracking dashboard.

Step-by-Step Solution

Evaluate the discovery requirements for the VMware VMs where network dependency mappings are required.

Determine that the AWS Application Discovery Agent must be installed on the VMs, since the Agentless Collector does not support collecting process-level network connections.

Network dependency mapping requires OS-level inspection of network sockets and processes, which is only supported by the agent-based tool.

Configure the Discovery Agents to bypass direct outbound network blocks.

Configure the agent settings on each VM to route outbound HTTPS discovery traffic through the forward HTTP proxy.

Since direct internet access is blocked on-premises, routing agent traffic through the proxy enables secure data delivery to AWS.

Address discovery for the database servers where agent installation is prohibited.

Collect inventory and performance metrics for the physical database servers and import them using the Migration Hub CSV template.

Manual import bypasses the need for agent installation on the database servers while still capturing their resource specs and utilization details for planning.

Group and track the servers in AWS Migration Hub.

Group the discovered VMs and imported database servers into logical applications within the AWS Migration Hub console.

This establishes a central tracking mechanism for the migration progress of the entire reservation system.
