A housing-authority project manager says the city's software-defined data center is complete because vSAN is in production. What is missing from that definition?
Select an answer to reveal the explanation.
Short Explanation
vSAN is the city's shared storage closet, not the whole building. An SDDC still needs virtualized hosts and virtualized networks sitting next to that storage. Calling the housing authority "done" because the file room is open leaves the rest of campus unbuilt.
Full Explanation
vSAN is the storage pillar of a VMware SDDC; an SDDC also requires virtualized compute and virtualized networking. A housing-authority claim that vSAN alone completes the SDDC misses compute virtualization (vSphere) and network virtualization (NSX-T). Storage virtualization is necessary in that stack narrative but not sufficient. vSAN does not include compute and network virtualization as a full SDDC by itself. Treating SDDC as only vCenter inventory with optional vSAN understates the pillars. Horizon pools do not replace the network pillar when vSAN is present. Exam caveat: municipalities may phase pillars, but exam definitions treat SDDC completeness as compute plus storage plus networking in software. Operational check: in the housing-authority architecture brief, explicitly list vSphere for compute, vSAN for storage, and NSX-T for networking before calling the civic SDDC complete. Keep municipal naming and change tickets aligned with the software objects so civic audits can trace intent. Prefer verifying with a non-production agency workload before promoting the same pattern to life-safety systems. Record realization state and underlay health in the runbook used by on-call city operators.
