Oracle 1Z0-497: Quintessential 12c

Oracle’s 12c exam for implementers covers a reasonable mix of topics.

1Z0-497: Oracle Database 12c: Essentials

Reviewer's Summary
Ample time, no exhibits, and a shallower depth than the 12c DBA track make this one of the easier Oracle certification exams to achieve.

1Z0-497 Exam Objectives

1Z0-497: Oracle Database 12c: Essentials is targeted at the employees of Oracle partners who will be selling or performing initial implementation of the Oracle 12c database. The information covered by this exam is not the "deep dive" that is expected of Oracle professionals who will be acting as database administrators. Instead, it covers subject areas that would be of most use to someone installing, configuring and troubleshooting a new Oracle 12c database.

For the most part, what is covered on this exam is a subset of the topics that are in Oracle’s 12c Database Administration track. The exam does, however, cover a number of reasonably advanced topics that are outside the scope of that track. These largely revolve around the new Maximum Availability Architecture (MAA) features that Oracle has implemented with 12c. The exam does not, on the other hand, cover these areas in sufficient depth for professionals who will be implementing them. The intent is presumably to ensure that test candidates are knowledgeable enough about the capabilities to be able to talk intelligently about them with customers. While I do not have a need for any of the MAA capabilities at the moment, I found them very interesting to read about. If I ever develop a need for that level of availability, I will be in a much better position to suggest a course of action to my employer.

The 1Z0-497 exam has a relatively small number of topics at 52, and these are spread among only 12 subject areas. The basic concepts covered by the exam include the following:

  • Database Concepts & Architecture
  • Software Installation and Maintenance
  • Administration & Configuration
  • 12c New Features
  • Maximum Availability Architecture
  • Backup and Recovery
  • Multitenant Architecture

As I noted earlier, the exam topics are mostly a subset of the Oracle 12c DBA track. Since I have already completed the 12c DBA OCP track, I did not find this exam to be particularly challenging. In addition, I took the exam several weeks after my experience with 1Z0-062 and I had done considerably more research on Oracle 12c between the two exams. That makes it difficult for me to judge how hard it would be for someone without the same background. I would certainly say that it was not the wolf in sheep’s clothing that I found the 1Z0-062 exam to be. This is especially true since I took the beta version of 1Z0-497, and the production exams tend to be a bit easier and have a lower time pressure.

The production version of the exam has 85 questions and a time limit of 120 minutes. This gives you about a minute and a half for each question. Since the exam had no exhibits, I doubt many test takers will feel any significant time pressure on the exam. Obviously you should pay attention to the clock, but for most people there should be enough time that rushing will be a greater danger than running out of time before finishing the exam. It is never wise to underestimate (and therefore under-prepare), but I believe most candidates will find 1Z0-497 to be one of the easier hurdles to clear. Good luck on the exam.
