Which are the key technologies of SmartMatrix 3.0? (Multiple Choice)

Question

Options

• ABack-end Interconnect I/O Module (BIM)
• BFC Front-end Interconnect I/O Module (FC FIM)
• CContinuous cache mirroring
• DiSCSI and NAS FIM

• A
  71% (30)
• D
  29% (12)

Explanation

SmartMatrix 3.0 is defined by three core architectural technologies: the Back-end Interconnect I/O Module (BIM) enables high-bandwidth, low-latency communication between controllers on the back end; the FC Front-end Interconnect I/O Module (FC FIM) provides high-performance Fibre Channel connectivity to hosts on the front end; and continuous cache mirroring ensures real-time data protection by synchronizing cache data across controllers, preventing data loss during failures. These three components together form the fundamental fabric of the SmartMatrix 3.0 architecture.

Option D is wrong because iSCSI and NAS FIM are host interface module types that exist as connectivity options, but they are not among the key defining technologies of the SmartMatrix 3.0 architecture itself - they are supplementary protocols, not architectural pillars.

Memory tip: Think "BIM + FIM + Mirror = SmartMatrix core." BIM handles the back, FC FIM handles the front, and continuous cache mirroring handles resilience - three layers (back, front, protection) = the three correct answers. iSCSI/NAS is a distractor because it sounds like a FIM variant, but it's not a key SmartMatrix 3.0 technology.
