    The first step to optimize the critical rendering path is:

    • analyze and characterize your critical path: number of resources, bytes, length.
    • optimize the number of critical bytes to reduce the download time (number of roundtrips)
    • minimize number of critical resources: eliminate them, defer their download, mark them as async, and so on
    • optimize the order in which the remaining critical resources are loaded: download all critical assets as early as possible to shorten the critical path length.

    Correct answer is:

    • analyze and characterize your critical path: number of resources, bytes, length.

    Explanation: The general sequence of steps to optimize the critical rendering path is:

    • Analyze and characterize your critical path: number of resources, bytes, length.
    • Minimize number of critical resources: eliminate them, defer their download, mark them as async, and so on.
    • Optimize the number of critical bytes to reduce the download time (number of roundtrips).
    • Optimize the order in which the remaining critical resources are loaded: download all critical assets as early as possible to shorten the critical path length.
