Which of the following aspects are reflected in the high reliability of Fusioninsight HD data? (Multiple choice)

Question

Options

• ADisaster recovery across data centers
• BKey data power-down protection
• CDisk hot swap
• DThird-party backup system integration

• A
  100% (49)

Explanation

All four options are correct because FusionInsight HD is designed with a multi-layered reliability architecture that addresses failures at every level. Disaster recovery across data centers (A) ensures business continuity when an entire site fails. Key data power-down protection (B) safeguards critical data during unexpected power loss, preventing corruption or loss at the hardware level. Disk hot swap (C) allows failed disks to be replaced without system downtime, maintaining continuous availability. Third-party backup system integration (D) extends reliability by allowing enterprises to plug in existing backup infrastructure, adding an extra recovery layer beyond what FusionInsight HD provides natively.

Since all options are correct, there are no distractors to dismiss - the question tests whether you know that FusionInsight HD's reliability is comprehensive, not limited to just one or two mechanisms.

Memory tip: Think of the acronym "DDDT" - Datacenter, Downtime (power), Disk, Third-party - four pillars covering the four common failure scenarios (site-level, power-level, hardware-level, and recovery-level). If a reliability feature addresses any of those failure points, it belongs in FusionInsight HD's design.
