Which of the following is true regarding the configuration of the IDSDM?

The statement regarding the configuration of the IDSDM that asserts one card can suffice but with no redundancy is accurate because the IDSDM, or Intelligent Dual SD Memory, is designed to use two SD cards to provide redundancy and ensure higher reliability of data storage. However, in scenarios where only one SD card is available, the system can still function with it, albeit without the protective benefits of redundancy. This means that if the single SD card fails, the system would not have a backup to rely on.

The other options do not correctly represent the capabilities of the IDSDM. The requirement for two SD cards serves to provide redundancy, which is crucial for maintaining data integrity in case one card fails. A configuration that supports only RAID-0 would not be suitable for IDSDM, as RAID-0 does not provide fault tolerance. Lastly, while using four SD cards may improve performance or capacity in some contexts, the baseline functionality of IDSDM does not necessitate that many cards for standard operations. Thus, the functionality with a single card, albeit without redundancy, correctly highlights a critical aspect of how this system can operate under less-than-ideal circumstances.
