I passed my exam. Cramkey Dumps provides detailed explanations for each question and answer, so you can understand the concepts better.

I recently used their dumps for the certification exam I took and I have to say, I was really impressed.

Ilyas

Definitely. I felt much more confident and prepared because of the Cramkey Dumps. I was able to answer most of the questions with ease and I think that helped me to score well on the exam.

That's amazing. I'm glad you found something that worked for you. Maybe I should try them out for my next exam.

Fatima

Hey I passed my exam. The world needs to know about it. I have never seen real exam questions on any other exam preparation resource like I saw on Cramkey Dumps.

Niamh Jul 22, 2026

That's true. Cramkey Dumps are simply the best when it comes to preparing for the certification exam. They have all the key information you need and the questions are very similar to what you'll see on the actual exam.

Question 21

An Exadata X9M-2 Elastic Rack with 4 Database Servers and 8 HC Storage Servers and 3-phase 24kVA 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?

Options:

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

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

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

The installation can go ahead, no change is required.

Question 23

What are two recommended configuration best practices for backup and recovery on Exadata?

Options:

Placing the backup network on dedicated switches installed in the top of the rack (ToR) has the benefits of isolating the backup network from other workloads and providing a greater level of control.

Even if the backup was limited to writing to four tape drives, eight channels could be specified to expedite the restore process.

The internal Recovery Appliance backup and restore processing is optimized when the RMAN FILESPERSET parameter is set to 1 for the level 1 incremental backup set.

When off-site long-term backup retention is needed, use Oracle Database Backup Cloud Service as a low-cost, offsite scalable storage for a disaster recovery solution.
