350-601 Compute Practice Question
An engineer is configuring a HyperFlex cluster with three nodes. Which three components are required for a functional cluster? (Choose three.)
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
✓
VMware vSphere or other supported hypervisor
HyperFlex requires at least three storage nodes for RF2, a vSphere cluster, and the HX Data Platform. A witness is needed for clusters with even number of nodes or for RF3? Actually for 3 nodes, witness is optional if RF2? Standard deployment: 3 nodes form a cluster; the witness is optional for 3 nodes but often recommended. The question expects the core components: storage nodes, vSphere, and HXDP. Witness is not mandatory for 3-node RF2 clusters.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A witness VM for quorum
Why it's wrong here
Witness is required for two-node clusters, but for three-node clusters it is optional; however, many deployments still use it. But the question asks for 'required' components. Typically, three nodes form a quorum without a witness.
- ✓
VMware vSphere or other supported hypervisor
Why this is correct
HyperFlex runs on a hypervisor; vSphere is the most common.
- ✓
HyperFlex HX Data Platform software
Why this is correct
HXDP is the core software that provides the converged data platform.
- ✗
Cisco UCS Manager for node management
Why it's wrong here
UCS Manager is not required; nodes can be standalone or managed by UCS Manager optionally.
- ✓
At least three storage nodes (converged or compute+storage)
Why this is correct
HyperFlex requires a minimum of three nodes for data replication with RF2.
