You are tasked with moving a legacy application from a virtual machine running inside your datacenter to an Amazon VPC. Unfortunately, this app requires access to a number of onpremises services and…

Importing the current virtual machine using AWS VM Import/Export allows the legacy application, its operating system, and all configurations to be moved to an EC2 instance in AWS without modification, directly addressing the 'without being reconfigured' requirement.

An Internet Gateway primarily allows public internet access and does not, by itself, establish a private VPN connection to an on-premises network for internal dependency access.

While crucial for DNS-based access, creating entries in Amazon Route 53 primarily addresses name resolution and assumes underlying network connectivity is already established; it is secondary to the foundational network connection and non-conflicting IP space.

Establishing an IP address space for the VPC that does not conflict with the on-premises network's IP space is fundamental for enabling proper routing and communication between the VPC instance and the on-premises dependencies.

An Elastic IP address provides a static public IP for an EC2 instance, which is used for external internet-facing communication, not for private access back to on-premises internal services.

An AWS Direct Connect link provides a dedicated private network connection between the Amazon VPC and the on-premises network, ensuring secure, high-bandwidth, and low-latency access for the migrated application to its internal dependencies.
