Which two statements are true for the Oracle Exadata Configuration Assistant (OECA)?

Question

Options

• AOECA reconfigures the size of disk groups and recreates grid disks.
• BOECA extends the hardware for the elastic configuration only.
• COECA allows one XT storage server in the configuration.
• DOECA's "Add Equipment" input option allows allocation of RU slots for customer equipment.
• EOECA facilitates PDU power selection initially and after equipment addition.

• A
  6% (2)
• B
  88% (28)
• C
  3% (1)
• D
  3% (1)

Explanation

B is correct because OECA's hardware extension capability is scoped exclusively to elastic configurations - it cannot extend non-elastic (fixed) Exadata configurations, making this a key architectural boundary to remember. E is correct because OECA manages PDU (Power Distribution Unit) power selection as part of both the initial rack build and any subsequent equipment additions, ensuring power capacity is validated at each stage.

Why the distractors fail: A is wrong because reconfiguring disk groups and recreating grid disks is handled by ASM/storage management tools, not OECA - OECA operates at the hardware/rack level, not the storage software level. C is wrong because OECA does not impose a restriction of a single XT storage server; that would be an oddly specific and arbitrary constraint. D is wrong because the "Add Equipment" function in OECA pertains to Oracle Exadata components, not allocating RU (rack unit) slots for customer third-party equipment.

Memory tip: Associate the two correct answers with "B-E = Build Elastically, watch your Electrical" - OECA extends hardware only in elastic mode (B) and always tracks power/PDU needs (E). If an answer implies OECA touches software layers (disk groups) or non-Oracle equipment slots, it's a trap.
