VCP-DCV vSphere Architecture, Products and Solutions Practice Question
An administrator is configuring a new iSCSI storage array for a vSphere cluster. The array supports multiple iSCSI targets. What is the recommended best practice for multipathing to ensure high availability and load balancing?
⚠ Common exam trap
Candidates often confuse logical separation (VLANs or multiple IPs on one NIC) with true physical path redundancy, leading them to select options that appear to provide multipathing but actually create a single point of failure.
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 multiple VMkernel ports for iSCSI, each bound to a separate physical NIC, and configure multiple iSCSI targets.
VMware best practices for iSCSI multipathing require multiple VMkernel ports, each bound to a separate physical NIC, and multiple iSCSI targets to provide both path redundancy and load balancing. This configuration leverages the Pluggable Storage Architecture (PSA) and native multipathing plugins (NMP) to distribute I/O across active paths while maintaining high availability through automatic path failover. Using separate VMkernel ports and NICs ensures that no single point of failure exists in the storage network.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use the management VMkernel port for iSCSI traffic to simplify configuration.
Why it's wrong here
Mixing management and storage traffic can cause performance issues and is not best practice.
- ✓
Create multiple VMkernel ports for iSCSI, each bound to a separate physical NIC, and configure multiple iSCSI targets.
Why this is correct
This provides path redundancy and load balancing.
- ✗
Configure a single physical NIC with multiple VLANs for iSCSI traffic.
Why it's wrong here
Single NIC is a single point of failure.
- ✗
Use a single VMkernel port for iSCSI and assign multiple IP addresses to it.
Why it's wrong here
Multiple IPs on one port does not provide redundancy at the network level.
