Question

Engineers are preparing to move guests to new compute and storage infrastructure. Basic network and SAN connectivity have been established. Which of the following options are valid NEXT steps to prepare for guest migration to the new infrastructure? (Select two.)

Options

  • ATag the live migration VLAN on the trunk to the new servers
  • BCorrectly size and provision NFS LUNs on the new storage
  • CZone HBAs
  • DPrep mirror VMs on new hosts for data migration
  • ETag the SAN trunks with the correct guest network VLANs

Why each option

After basic network and SAN connectivity are established, the immediate next steps for guest migration are tagging the live migration VLAN on trunk ports to the new servers and preparing mirror VMs on the destination hosts.

ATag the live migration VLAN on the trunk to the new serversCorrect

Tagging the live migration VLAN on trunk links to the new servers enables the hypervisor to carry vMotion or live migration traffic, which uses a dedicated VLAN separate from management and guest VM traffic - this must be in place before any live migration can occur.

BCorrectly size and provision NFS LUNs on the new storage

NFS LUN provisioning applies to NAS-based storage, but the scenario explicitly states SAN connectivity is already established - introducing NFS is outside the described infrastructure and not a required next step.

CZone HBAs

Zoning HBAs in the SAN fabric is a prerequisite step required before establishing SAN connectivity, which the scenario states has already been completed.

DPrep mirror VMs on new hosts for data migrationCorrect

Preparing mirror or shadow VMs on the new destination hosts stages the workloads on the new infrastructure, enabling data synchronization and allowing a controlled cutover with minimal downtime during the final migration step.

ETag the SAN trunks with the correct guest network VLANs

SAN trunk ports are dedicated to storage traffic on storage VLANs and must never be tagged with guest network VLANs, as mixing these traffic types introduces security risks and performance degradation.
