Certified Data Engineer Associate Exam - Question 2


Which of the following describes a scenario in which a data team will want to utilize cluster pools?

Show Answer
Correct Answer: AE

Cluster pools are utilized to reduce the startup time of clusters by having pre-allocated resources ready to use. This ensures that tasks such as report refreshes can be completed more quickly and efficiently. Therefore, a scenario in which an automated report needs to be refreshed as quickly as possible is a suitable description of when a data team would want to utilize cluster pools.

Using cluster pools reduces the cluster startup time. So in this case, the reports can be refreshed quickly and not having to wait long for the cluster to start

A. An automated report needs to be refreshed as quickly as possible. Cluster pools are typically used in distributed computing environments, such as cloud-based data platforms like Databricks. They allow you to pre-allocate a set of compute resources (a cluster) for specific tasks or workloads. In this case, if an automated report needs to be refreshed as quickly as possible, you can allocate a cluster pool with sufficient resources to ensure fast data processing and report generation. This helps ensure that the report is generated with minimal latency and can be delivered to stakeholders in a timely manner. Cluster pools allow you to optimize resource allocation for high-demand, time-sensitive tasks like real-time report generation.

Considering the recommendation to create pools based on workloads and to pre-populate pools to ensure instances are available when clusters need them, the most suitable option would be: E. An automated report needs to be runnable by all stakeholders. This aligns with the concept of pre-populating pools to ensure that instances are readily available when needed, enabling the automated report to be executed promptly whenever stakeholders require it without waiting for instance acquisition.

E is correct for sure. For data team , their tasks is not just to refresh a report. They equally want to share the cluster for running their queries. Please read at below: https://docs.databricks.com/en/compute/pool-best-practices.html#create-pools-based-on-workloads

A : I think cluster pools are used mainly to accellerate cluster start up by using vms somehow.
