Difficulty: MediumHybrid and VMware Cloud on AWS Migrations

An enterprise is planning to migrate its on-premises VMware vSphere environment containing 80 virtual machines (VMs) to a VMware Cloud on AWS SDDC. The migration has the following technical requirements:

* A critical database cluster of 5 VMs must be migrated with zero downtime during replication and cutover to maintain continuous application availability.
* The remaining 75 application VMs can tolerate a brief service interruption of up to 15 minutes during an off-peak scheduled maintenance window.
* All VMs must retain their existing on-premises IP addresses post-migration to prevent breaking hardcoded application configurations.
* The migration traffic must traverse a private connection using an existing 1 Gbps AWS Direct Connect connection.

Which combination of VMware HCX migration methods and network configurations should the Solutions Architect select to meet these requirements? (Select TWO.)

  1. Use VMware HCX Replication Assisted vMotion (RAV) to migrate the database VMs, and use VMware HCX Bulk Migration to migrate the application VMs with a scheduled switchover.Answer
  2. Establish a VMware HCX Layer 2 Network Extension over the Direct Connect connection to stretch the on-premises VLANs to the VMware Cloud on AWS SDDC.Answer
  3. C
    Use VMware HCX Cold Migration for all database and application VMs to optimize migration bandwidth usage on the Direct Connect connection.
  4. D
    Configure a Direct Connect Gateway directly to route the Layer 2 traffic between the on-premises network and the SDDC without deploying an HCX network extension.
  5. E
    Associate a Route 53 Private Hosted Zone with the VMware Cloud on AWS VPC to dynamically update DNS records and translate VM IP addresses during the migration.

Answer

The correct configurations are using VMware HCX Replication Assisted vMotion (RAV) for database VMs along with Bulk Migration for application VMs, and establishing a VMware HCX Layer 2 Network Extension over the Direct Connect connection.
To satisfy the requirements, the Solutions Architect should select VMware HCX Replication Assisted vMotion (RAV) for the database VMs to ensure zero downtime, use VMware HCX Bulk Migration for the remaining application VMs to allow scheduled parallel switchovers within their 15-minute downtime window, and establish a VMware HCX Layer 2 Network Extension over Direct Connect to preserve IP addresses.

Step-by-Step Solution

1
Analyze the downtime tolerance of the workloads.
The database VMs require zero downtime, which mandates HCX Replication Assisted vMotion (RAV). The application VMs can tolerate up to 15 minutes of downtime, making HCX Bulk Migration (which uses replication followed by a scheduled reboot switchover) the most efficient and scalable choice.
Matching migration methods with workload requirements ensures that application availability matches defined objectives.
2
Determine the network requirements for IP preservation.
To preserve on-premises IP addresses without updating hardcoded application configurations, a Layer 2 network extension must be configured.
Layer 2 extensions stretch VLANs across hybrid environments, preventing IP address changes.
3
Select the appropriate network path.
The migration traffic must travel over a private connection, so VMware HCX should be configured to run over the Direct Connect Private VIF rather than the public internet.
Direct Connect Private VIF ensures secure, high-throughput, private routing of HCX replication and vMotion traffic.

Key Concept

Selecting the appropriate VMware HCX migration methods (Replication Assisted vMotion and Bulk Migration) and extending the Layer 2 network over a private Direct Connect path to satisfy workload availability and IP preservation requirements.
