Question
Which of these rules apply when you add preemptible workers to a Dataproc cluster (select 2 answers)?
Options
- APreemptible workers cannot use persistent disk.
- BPreemptible workers cannot store data.
- CIf a preemptible worker is reclaimed, then a replacement worker must be added manually.
Why each option
Preemptible workers in Dataproc are ephemeral and restricted from storing data persistently, but replacements can be handled automatically rather than manually.
APreemptible workers cannot use persistent disk.
BPreemptible workers cannot store data.
CIf a preemptible worker is reclaimed, then a replacement worker must be added manually.
Dataproc supports automatic replacement of reclaimed preemptible workers through its managed autoscaling and repair mechanisms; manual addition of replacement workers is not required.
