VCP-DCV Configure and Manage vSphere Storage Practice Question
Exhibit
Error: Cannot add host 'esxi-05.lab.local' to vSAN cluster. Cause: Host esxi-05.lab.local does not have a VMkernel interface with vSAN traffic enabled. VMkernel interfaces on host: vmk0: Management (10.0.0.5) vmk1: vMotion (10.0.1.5) vmk2: Provisioning (10.0.2.5)
Refer to the exhibit. An administrator attempts to add a host to a vSAN cluster and receives this error. Which step should the administrator take to resolve the issue?
⚠ Common exam trap
The trap is assuming any existing VMkernel adapter can be reused for vSAN; the exam tests whether you know vSAN requires its own dedicated, vSAN-enabled VMkernel interface, not just any vmk.
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
✓
Create a new VMkernel adapter (vmk3) on the host's network and enable vSAN traffic.
vSAN requires a dedicated VMkernel adapter with the vSAN traffic service enabled, and the error indicates no such adapter exists on the host. Creating a new vmk3 and enabling vSAN traffic on it satisfies the prerequisite without disturbing existing management or vMotion traffic.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reconfigure the vMotion interface (vmk1) to also carry vSAN traffic.
Why it's wrong here
Best practice is to not share vSAN with vMotion; also the vSAN service must be enabled.
- ✗
Add the host to the cluster without vSAN and enable vSAN later.
Why it's wrong here
Adding the host without vSAN leaves its local disks unclaimed and contributes no capacity or fault domains, so the cluster remains degraded. This suits staged rollouts where disks or firmware are not yet ready, but the exhibit's error concerns vSAN network configuration, which must be fixed before joining.
- ✓
Create a new VMkernel adapter (vmk3) on the host's network and enable vSAN traffic.
Why this is correct
Creating a dedicated VMkernel adapter with vSAN traffic enabled satisfies the cluster's requirement for a vSAN-capable vmknic on the host. vSAN cannot join a host whose existing adapters lack this service enabled, so adding vmk3 and ticking vSAN traffic provides the necessary network path for cluster communication.
- ✗
Enable vSAN traffic on the existing vmk0 interface.
Why it's wrong here
vmk0 is used for management; mixing vSAN with management is possible but not best practice; however, the error indicates no vSAN interface exists, so enabling on an existing interface could work but a dedicated interface is recommended.
