Read the first 7 System Architecture & Design flashcards as text

  1. When architecting a cloud-based digital asset management (DAM) system, which approach best addresses the challenge of vendor lock-in?

    Answer: Use open standards for metadata and open file formats with multi-cloud storage abstraction

    Open metadata standards and storage abstraction layers allow assets to be moved between providers without re-ingestion or data loss, minimizing vendor dependency.

  2. In a digital imaging system, what is the role of a thumbnail service in the overall architecture?

    Answer: To generate and cache lower-resolution previews on demand without modifying originals

    A thumbnail service generates reduced-resolution previews on demand and caches them separately, preserving the original master file integrity.

  3. A sports photography agency requires images to be available for licensing within 5 minutes of capture at an event. Which system architecture best supports this requirement?

    Answer: Wireless camera tethering to on-site laptop with FTP push to cloud ingest pipeline

    Wireless camera tethering with automated FTP push to a cloud ingest pipeline enables near-real-time delivery from capture point to the licensing system.

  4. Which image file format is best suited as a master archive format for a long-term digital preservation system requiring lossless quality and broad future compatibility?

    Answer: TIFF with LZW compression

    TIFF with LZW compression offers lossless quality, wide long-term software support, and is the archival standard recommended by major digital preservation institutions.

  5. In a digital imaging pipeline, what is the primary purpose of a checksum generated during file ingest?

    Answer: To verify that the ingested file is bit-for-bit identical to the source and detect corruption

    A checksum (e.g., MD5 or SHA-256) computed at ingest and verified after storage confirms the file was not corrupted during transfer or writing.

  6. A digital imaging system must process 10,000 images per hour with AI-based auto-tagging. Which compute architecture is most cost-effective for this workload?

    Answer: GPU-accelerated cloud instances scaled dynamically to match processing demand

    GPU-accelerated cloud instances leverage parallel processing for AI inference and can scale up during peak loads and down during off-peak periods, optimizing cost.

  7. What is the significance of bit depth in a digital imaging system's processing pipeline?

    Answer: It defines the number of tonal values available per channel, affecting dynamic range and editing headroom

    Bit depth determines the number of discrete tonal steps per channel; higher bit depth provides more editing headroom and smoother gradients with less banding.
