Oracle 1Z0-902 Exam - Topic 2 Question 75 Discussion

Actual exam question for Oracle's 1Z0-902 exam

Question #: 75
Topic #: 2

A new Exadata Quarter Rack with 2 Database Servers and 3 HC Storage Servers and 3-phase 15kVA PDUs is being installed in a Data Center. However, the Data Center is only providing enough power for a single cable from each PDU.

Which statement is correct?

AThe installation can go ahead, no change is required.

BThe installation cannot proceed until two power feeds are available per PDU.

CA splitter cable can be used to provide power to all PDU cables.

DThe power cables from the servers to the PDUs can be rearranged inside the rack following OECA guidance to utilize a single PDU power cable.

Show Suggested Answer

Suggested Answer: A

According to the Oracle Exadata Database Machine X9M-2 Data Sheet1, each PDU has two power input cables that can be connected to separate power sources for redundancy. However, if only one power source is available per PDU, then a single cable can be used to provide sufficient power for normal operation.

I think I saw a similar question in our practice exams about power distribution. If I recall correctly, we definitely need more than one power feed, which makes me think B is the right choice.

I’m not entirely sure, but I feel like using a splitter cable might not be the best practice. It seems risky, so I’d probably avoid option C.

I remember something about power requirements for Exadata setups, and I think we need two feeds for redundancy. So, I’m leaning towards option B.
