Exadata X9M System Installation and Configuration

Question

You have been asked to design a backup solution for an Exadata X9M-2 Quarter Rack with Extreme Flash Storage Servers connected to a new ZFS Storage Appliance ZS7 with 2 Storage Controllers with 100Gb Ethernet cards and 3 Storage Trays. You are using Oracle Exadata Configuration Assistant to validate the rack layout. 1. Use "Add Equipment" to add the Exadata X9M EF Storage Servers, starting from RU10. 2. Use drop down to add ZFS Storage Appliance Controllers. 3. You cannot add ZFS Storage Appliance to an Exadata Rack. 4. Use "Add Equipment" to add the ZFS Storage Trays, starting from RU1. 5. Use drop down to add ZFS Storage Trays. 6. Use "Add Equipment" to add the Exadata X9M Database Servers, starting from RU16. 7. Use "Add Equipment" to add the Exadata X9M EF Storage Servers, starting from RU1. 8. Use drop down to add Exadata X9M EF Storage Servers. 9. Use "Add Equipment" to add the ZFS Storage Controllers, starting from RU27. 10. Use drop down to add Exadata X9M Database Servers. 11. Use "Add Equipment" to add the ZFS Storage Trays, starting from RU31. Which of these steps are correct and what is their correct order?

Explanation

Option D is correct because in Oracle Exadata Configuration Assistant (OECA), Exadata-native components (Database Servers and EF Storage Servers) are configured via dropdown menus, while ZFS Storage Appliance components (Controllers and Trays) are added via "Add Equipment" since they are external appliances. Steps 10 and 8 correctly use dropdowns for the Exadata X9M Database Servers and EF Storage Servers respectively, while steps 9 and 11 correctly use "Add Equipment" for the ZFS Storage Controllers (RU27) and ZFS Storage Trays (RU31).

Why distractors fail:

  • A (10, 8, 2, 5) is wrong because steps 2 and 5 use a dropdown for ZFS components, which is the wrong mechanism - ZFS parts require "Add Equipment."
  • B (4, 1, 6, 9) is wrong because steps 1 and 6 use "Add Equipment" for Exadata EF Storage Servers and Database Servers, which should use the dropdown, and the RU starting positions are incorrect.
  • C is factually false - you can add a ZFS Storage Appliance to an Exadata rack configuration in OECA.
  • E (7, 6, 9, 11) uses "Add Equipment" for both Exadata component types (wrong mechanism) and starts EF Storage Servers from RU1 instead of the correct position.

Memory tip: Think "Exadata = Drop-in (dropdown)" because it's the primary rack product and is natively understood by OECA, while "ZFS = Add-on (Add Equipment)" because it's supplemental backup hardware being bolted on.
