                                Oracle 1z1-485 Exam — Asked and Answered

                                At its core, the 1z1-485 exam is Oracle's gatekeeper for the Oracle Exadata Database Machine 2014 Certified Implementation Specialist certification — a Specialist-level credential. It examines how well you apply the Oracle Exadata Database Machine 2014 Implementation Essentials objectives to realistic scenarios, which is why hands-on candidates tend to outperform pure memorizers. The credential also links into a wider path covering Oracle Engineered Systems Certification, Exadata Database Machine Models X3-2 and X3-8 Implementation Specialist, so it works as both a standalone achievement and a stepping stone. In a market where certificates increasingly signal ability, passing 1z1-485 is a concrete, verifiable upgrade to your professional profile.

                                The Oracle Exadata Database Machine 2014 Implementation Essentials exam draws its questions from 6 domains, starting with Performance & Database Features, Exadata Smart Features & Offloading, and Deployment & Configuration. Smart candidates read weightings as a resource map: heavy domains get the deepest practice, light domains get efficient review. You'll find the complete domain list in the exam topics section above — let it drive your schedule.

                                The Oracle Exadata Database Machine 2014 Implementation Essentials exam fits 70-71 questions into 120 minutes. Convert that into a pace before exam day: total minutes divided by question count gives you a per-item budget, and the discipline to flag-and-return when something overruns it. Practicing under a live timer — the ExamPrepAway test engines run one on every session — turns that discipline into reflex, so the clock works for you instead of against you.

                                The Oracle Exadata Database Machine 2014 Implementation Essentials exam requires 67% to pass, and Oracle charges USD 245 (varies by region) per attempt — full price, every time, including retakes. That pricing structure rewards preparation: run timed self-assessments with ExamPrepAway practice questions, and only book your seat once your scores clear the bar consistently across multiple sessions. One well-prepared attempt is dramatically cheaper than two hopeful ones.

                                Officially, the Oracle Exadata Database Machine 2014 Implementation Essentials exam uses these formats: Multiple Choice. Formats shape strategy — long scenario stems reward reading the final question sentence first, while multi-select items punish partial knowledge. The fix is exposure: ExamPrepAway's 71 practice questions rehearse you in every listed format until the mechanics are second nature and only the content demands your attention.

                                Oracle currently delivers the 1z1-485 exam in English, Japanese. Select whichever language lets you parse questions fastest under time pressure — borderline scores are often decided by reading speed, not knowledge. If English is your choice, daily sessions with ExamPrepAway's English 1z1-485 practice questions build exactly the vocabulary the exam uses.

                                The credential earned through the Oracle Exadata Database Machine 2014 Implementation Essentials exam remains valid for Non-expiring (version-specific). Note the expiry date the day you pass and start researching recertification options well in advance — planned renewals are routine, last-minute ones are stressful. Because recertification rules belong to Oracle and change over time, verify the current policy on the official certification page as your renewal window approaches.

                                The content is identical — 71 expert-verified questions — so choose by lifestyle:

                                • PDF version — printable, expert-prepared, instantly downloadable, readable anywhere. Includes 365 days of free updates; a free demo is available.

                                • Online Test Engine — opens in any browser on Windows, Mac, Android, or iOS, with test history and performance review. Once loaded, your material stays accessible even when you go offline.

                                Commuters and travelers usually live in the online engine; desk-bound studiers prefer the desktop version; annotators swear by the PDF.

                                The mpstat output from OS Watcher shows a database node as being 90% idle on an average. What would you do to get a full picture of CPU utilization on the entire Exadata RAC cluster?

                                • B. Look for an increase in batch job servicing times.

                                When an Exadata Storage Server hard disk failure alert is received, what manual action must you take to restore the system to full redundancy?

                                • A. No manual action is required because ASM rebalancing isautomatic.
                                • B. Run RMAN REPAIR FAILUR
                                • C. No manual action is required because Automatic Storage Management (ASM) fast mirror resync is automatic
                                • D. Replace the disk and run MegaCLI to rebuild the degenerate mirror.
                                • E. Replace the disk and manually copy the mirror extents to the new drive.

                                Why is ASM High redundancy an important configuration choice when rolling Exadata Storage Server patching is planned?

                                • A. High redundancy speeds up ASM fast mirror resync when a cell is brought back online after patching.
                                • B. Normal redundancy provides the same protection during rolling patching, so High redundancy is not important inthis case
                                • C. High redundancy forces ASM rebalance before allowing disks to be taken offline.
                                • D. High redundancy protects from partner disk failure while a cell is offline being updated.
