      Hi Shiv, was this model paper enough ? There are some contradictions in the answers and some even say that the questions here are no more valid as the pattern has changed… Did you give the exam in the prometric or through exams local ?

    There are also virtual memory constraints that a container must meet.
    If a container’s virtual memory usage exceeds a given multiple of the allocated physical memory, the
    node manager may terminate the process.
    The multiple is expressed by the yarn.nodemanager.vmem-pmem-ratio property, which defaults to 2.1.
    In the example 4096, the virtual memory threshold above which the task may be terminated is
    8601 MB (8.4 GB), which is 2.1 × 4096 MB.

      You are right but Isn’t that 8.4? Plain maths 🙂

      Well answer is 8.2 but they have a typo there in the question from Cloudera. They should have written 8.4, not 8.2.

      I passed months ago…

        Hi Carrijo,

        I’m planning to take CCA-500 next week. I believe these questions are similar to the one that I may receive in exam.

        According to you the questions are entirely different now? Is dumps not stable?
