Explanation:
B: Updating Exadata Database Servers (compute nodes).The software and firmware components that are updated for a specific release depend on the current Exadata software release the database server is running and the release you are updating to. Linux operating system packages and Exadata software are always updated while firmware may be updated for only a small selection of the components or not at all.
D: The storage cells (storage servers/nodes) contain HBAs, and spare PCI I/O slots.
