   Which characteristic is most associated with the streaming data layout model?

   • AProvides the lowest latency for individual random reads.
   • BData is distributed in small stripes across many nodes.
   • COptimized for small, random I/O operations.
   • DDesigned for large-block, sequential reads and writes.

   A PowerScale cluster is used for a web application that performs many small random reads and writes, and also for a log processing system that reads large log files sequentially. The storage team is considering switching from streaming to concurrent layout for all files. What is the most likely impact on the log processing system?

   • AThere will be no impact because sequential reads are not affected by data layout.
   • BSequential read throughput may decrease because concurrent layout is optimized for random access, not sequential.
   • CSequential read latency will decrease because concurrent layout reduces seek time.
   • DSequential read throughput will increase because concurrent layout uses larger block sizes.

   Which of the following is a typical use case for streaming data layout?

   • AA virtual desktop infrastructure (VDI) environment with many small random I/Os.
   • BA real-time trading system that requires low-latency random access to market data.
   • CA backup system that writes large, sequential data streams to disk.
   • DA data analytics platform performing random reads on a large dataset.

   Which statement correctly compares concurrent and streaming data layout models?

   • AConcurrent layout distributes data in small stripes for parallel access, while streaming layout uses large contiguous blocks for sequential access.
   • BConcurrent layout uses large contiguous blocks, while streaming layout uses small stripes.
   • CConcurrent layout is optimized for sequential access, while streaming layout is optimized for random access.
   • DBoth layouts use the same data distribution but differ only in the file system used.

   What is a key performance benefit of the concurrent data layout model?

   • AIt reduces storage overhead by using data deduplication.
   • BIt minimizes the number of nodes required to store data.
   • CIt allows multiple clients to read and write different parts of the same file concurrently without contention.
   • DIt maximizes sequential read throughput for a single client.
