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 for new compute and storage, the next steps for guest migration include configuring the live migration network and preparing for data replication.

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

Live migration often uses a dedicated network to transfer VM memory and state, so tagging the live migration VLAN on the trunk to the new servers ensures the necessary network path is available for the migration process.

BCorrectly size and provision NFS LUNs on the new storage

NFS is a file-level protocol and does not use LUNs, which are associated with block storage; therefore, 'NFS LUNs' is a contradictory term.

CZone HBAs

While zoning HBAs is essential for SAN connectivity, the question states 'Basic network and SAN connectivity have been established,' implying this foundational step is already in place or is part of the established connectivity, making A and D more direct next steps for the guest migration process itself.

DPrep mirror VMs on new hosts for data migrationCorrect

Preparing mirror VMs on new hosts for data migration is a common strategy to pre-copy the virtual machine's data, minimizing downtime during the final cutover by replicating the VM state to the new infrastructure.

ETag the SAN trunks with the correct guest network VLANs

SAN trunks carry storage traffic, while guest network VLANs carry virtual machine network traffic; these are separate network planes and should not be tagged on the same trunks for these distinct purposes.
