VCP-VVF IT Architectures Technologies Standards Practice Question
An enterprise architect is planning the network architecture for a vSphere Foundation 9.0 cluster running vSAN. Which THREE network design practices are recommended for vSAN VMkernel adapters? (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
✓
Configure dedicated physical NIC uplinks or use Network I/O Control (NIOC) to prioritize vSAN bandwidth.
vSAN network best practices include isolating vSAN traffic on dedicated VLANs, using Jumbo Frames (MTU 9000), and configuring dedicated physical uplinks or NIOC shares to prevent contention.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure dedicated physical NIC uplinks or use Network I/O Control (NIOC) to prioritize vSAN bandwidth.
Why this is correct
Correct. Reserving bandwidth via NIOC or dedicated uplinks ensures vSAN traffic is not starved by other workloads.
- ✗
Route all vSAN storage traffic through public unencrypted internet gateways.
Why it's wrong here
vSAN traffic must remain within secure internal data center networks, never over the public internet.
- ✓
Isolate vSAN traffic on a dedicated VLAN or separate physical network segment.
Why this is correct
Correct. Isolating vSAN traffic improves performance and security.
- ✗
Disable TCP checksum offloading on all ESXi host physical network adapters.
Why it's wrong here
Checksum offloading should remain enabled to optimize host CPU efficiency.
- ✓
Configure Jumbo Frames (MTU 9000) across the physical switch path and VMkernel adapters.
Why this is correct
Correct. Jumbo frames increase storage throughput and reduce CPU overhead for vSAN.
