350-601 Compute Practice Question
An engineer is configuring a UCS server for VMware ESXi. The service profile must support NPIV for virtual machine SAN connectivity. Which two conditions must be met? (Choose two.)
⚠ Common exam trap
Cisco often tests the misconception that NPIV requires a fabric failover policy or dual-fabric mode, when in fact NPIV only requires unique WWPNs and proper VSAN association, with failover handled at the fabric level or by the hypervisor.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The WWPN must be unique per virtual machine
NPIV (N_Port ID Virtualization) requires each virtual machine to have a unique World Wide Port Name (WWPN) so that the SAN fabric can distinguish and manage each VM's storage traffic independently. This allows multiple virtual machines to share a single physical HBA while each appears as a separate initiator to the SAN.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The WWPN must be unique per virtual machine
Why this is correct
NPIV assigns unique WWPNs to each VM for SAN access.
- ✓
The vHBA must be associated with a VSAN
Why this is correct
VSAN association is necessary for Fibre Channel connectivity.
- ✗
The vHBA must be set to 'Fabric: A' only
Why it's wrong here
NPIV can work on single or dual fabric; fabric A only is restrictive but not required.
- ✗
The vHBA must be set to 'Fabric: dual' mode
Why it's wrong here
Dual fabric is optional and does not dictate NPIV capability.
- ✗
The vHBA must be created with a fabric failover policy
Why it's wrong here
Failover policy is independent of NPIV support.
