Q81

You are configuring a Greenplum cluster. What happens if you set the `max_connections` parameter too high?

  • A Improved performance for all queries
  • B Potentially exceed resource limits
  • C Automatically resolve connection issues
  • D No impact on system performance
Explanation Setting `max_connections` too high can lead to resource exhaustion, impacting system stability and performance.
Q82

Which service in Greenplum allows for automated data ingestion?

  • A Greenplum Data Connector
  • B Tanzu Kubernetes Service
  • C Greenplum Data Federation
  • D Pivotal Cloud Cache
Explanation The Greenplum Data Connector automates data ingestion, while the others serve different purposes.
Q83

A company needs to optimize query performance on large datasets. What is a crucial step?

  • A Increase storage capacity
  • B Configure partitioning
  • C Add more nodes
  • D Upgrade network speed
Explanation Configuring partitioning can significantly optimize query performance on large datasets, while the other options might help but are not specific solutions.
Q84

What happens when a Greenplum server exceeds its memory limit during a query?

  • A Query execution is terminated
  • B Query uses disk space for processing
  • C Server automatically restarts
  • D Performance improves temporarily
Explanation When memory is exceeded, Greenplum uses disk space for processing, whereas the other options do not accurately describe the behavior.
Q85

Which service manages distributed query execution in Greenplum?

  • A Query Coordinator
  • B Data Warehouse
  • C Client Connection
  • D Backup Service
Explanation The Query Coordinator distributes queries across segments, managing execution; others do not specifically manage query distribution.
Q86

A company needs to ingest high-velocity data in real-time. Which Greenplum feature is best suited?

  • A Data Mart
  • B Streaming Data Ingestion
  • C Batch Load
  • D Snapshot Replication
Explanation Streaming Data Ingestion allows real-time data flow; batch load doesn't support real-time processing effectively.
Q87

What happens when a Greenplum segment node becomes unavailable?

  • A System crashes immediately
  • B Query execution continues with retries
  • C Data is lost permanently
  • D Only the failed node restarts
Explanation Queries can re-route to available segments, as Greenplum maintains redundancy; system does not crash on a segment failure, nor does it lose data permanently.
Q88

Which component manages fault tolerance in Greenplum?

  • A Master node
  • B Segment node
  • C Data Warehouse
  • D Backup Service
Explanation The Segment node handles data distribution and fault tolerance for the cluster, while the Master node does not manage faults directly.
Q89

A company needs to improve their language support for Greenplum extensions. Which extension should they use?

  • A PL/pgSQL
  • B PL/Java
  • C PL/Python
  • D PL/R
Explanation PL/Python provides extensive language support for data analysis, while the others focus on different programming environments or are less pertinent.
Q90

You are configuring replication in Greenplum. What happens when a segment fails during a data write?

  • A Data is always lost
  • B System halts until fixed
  • C Write retries without data loss
  • D Master node takes control
Explanation Greenplum uses replication for resilience, attempting retries without losing data.
