Configure and Manage vSphere Storage practice questions

This domain covers configuring and managing vSphere storage, including VMFS, NFS, iSCSI, Fibre Channel, datastore clusters, and multipathing. It tests your ability to select the right path selection policy, enable Storage DRS for I/O balancing, and troubleshoot performance after array changes. Expect scenario-based questions on real-world storage design and optimization.

Courseiva uses original exam-style practice questions designed for learning and revision. The goal is to understand the concepts, recognise exam patterns, and improve through explanations — not memorise copied exam dumps.

What the exam tests

What to know about Configure and Manage vSphere Storage

You must be able to configure datastore clusters with Storage DRS, select appropriate path selection policies, and troubleshoot storage performance. The most important thing is to correctly enable and configure Storage DRS I/O balancing and choose Round Robin for FC multipathing.

Configuring datastore clusters and enabling Storage DRS for I/O latency balancing

Selecting path selection policies like Round Robin for maximum throughput

Troubleshooting VMFS6 performance after array firmware upgrades

Managing iSCSI and Fibre Channel multipathing on ESXi hosts

Watch out for

Common Configure and Manage vSphere Storage exam traps

  • ▸Assuming Storage DRS balances based on I/O latency without enabling the I/O metric option in the datastore cluster settings.
  • ▸Choosing Most Recently Used (MRU) for Fibre Channel arrays when Round Robin is required to use all paths and maximize throughput.
  • ▸Overlooking that a single VMFS6 datastore can become a bottleneck for a high-IOPS VM like SQL Server, leading to performance issues.

Can I practise just Configure and Manage vSphere Storage questions in a focused session?
Yes — the session launcher on this page draws every question from the Configure and Manage vSphere Storage domain. Use a 10-question session first to gauge your baseline, then move to 20 or 30 once the weak spots are clear.
