A city GIS database runs on persistent block volumes attached to compute hosts that are scheduled for retirement next month. What must operations complete before those hosts are decommissioned?
Select an answer to reveal the explanation.
Short Explanation
Persistent database disks outlive the boxes they hang on—like moving filing cabinets before you demolish the office. Back them up and migrate the data first; retiring the host without a data plan is how cities lose the map.
Full Explanation
Persistent volumes retain application data independently of the compute instance life cycle. Before host retirement or EOL decommissioning, operations must ensure backups exist and migrate data to replacement hosts or storage so citizen-facing systems continue. Treating persistent volumes as disposable, or assuming they move automatically with CPU power-off, risks irreversible data loss.
