In your opinion, what is the future of Oracle Grid?
Interviewers ask questions about your opinion of a specific topic knowing that there is no right or wrong answer. They seek to understand your opinion, whether it is well reasoned, based on readily available information, and clearly communicated. Ticking each of these boxes will provide the information the interviewer is seeking and demonstrate your qualifications for this role.
When responding to a question that asks for your opinion on a topic, you should be comfortable providing the interviewer with your opinion as long as it is well thought out and can be substantiated. If you don't have the information or background needed to respond to the question, you should communicate this to the interviewer. The main thing to avoid is fabricating an answer. Interviewers will immediately recognize this and will ding you for attempting to bluff them rather than credit you for your creativity.
"In my opinion, Oracle Grid software is becoming more capable of supporting high availability (HA) for Oracle databases and other applications, including those from Oracle. There are more built-in features and functionality in version 12c, which is easier to deploy pre-built solutions available for most Oracle applications."
