Difficulty: EasyInfrastructure Migration with AWS Application Migration Service (MGN)

During a planned migration to AWS, an administrator installs the AWS Application Migration Service (MGN) agent on a source server. Although the installation succeeds, the replication status remains in a disconnected state because replication data traffic is blocked. Which network configuration must be applied to resolve this connectivity issue?

  1. Configure the local firewall and target security groups to permit traffic on TCP port 1500 to the replication servers in the staging area.Answer
  2. B
    Associate a private hosted zone in Amazon Route 53 with the staging VPC to resolve the hostnames of the replication servers.
  3. C
    Configure a Direct Connect gateway to handle transitive routing between the source network and multiple VPCs via AWS Transit Gateway.
  4. D
    Route outbound replication traffic through a single NAT Gateway deployed in one Availability Zone of the staging VPC.

Answer

Configure the local firewall and target security groups to permit traffic on TCP port 1500 to the replication servers in the staging area.
The correct option addresses the direct requirement of AWS Application Migration Service (MGN), which is that the replication agent installed on the source server requires outbound access over TCP port 1500 to transmit data blocks to the replication servers in the staging area subnet.

Step-by-Step Solution

1
Identify the network protocol and port required by the AWS Application Migration Service (MGN) replication agent for data replication.
The MGN replication agent requires outbound communication over TCP port 1500.
Data replication blocks are transmitted from the source server to replication servers over TCP port 1500.
2
Check the local firewall on the source server and target security groups in the AWS staging area VPC.
Confirm that TCP port 1500 is allowed outbound from the source server and inbound to the replication servers.
If TCP port 1500 is blocked along the path, replication cannot initiate even if the agent is installed successfully.
