Q41

A company needs to optimize data loading in Greenplum. What should they consider?

  • A Using psql for loading
  • B Parallel Data Loading
  • C Batch Query Processing
  • D Single-threaded connections
Explanation Parallel Data Loading maximizes throughput during data ingestion, unlike single-threading which is less efficient.
Q42

You are configuring a Greenplum cluster. What happens if standby servers are not configured?

  • A Cluster will not operate
  • B Data will be lost on failure
  • C Read requests will fail
  • D Greenplum will run in read-only mode
Explanation Without standby servers, a failure can lead to data loss because there's no backup to switch to.
Q43

Which service in VMware Tanzu Greenplum is responsible for managing data distribution across segments?

  • A Data Distribution Manager
  • B Segment Coordinator
  • C Resource Manager
  • D Master Data Service
Explanation Segment Coordinator handles data distribution, while others manage different aspects of the database.
Q44

A company needs to ensure data redundancy in its Greenplum cluster. What should they configure?

  • A Master Mirroring
  • B Segment Replication
  • C Data Archiving
  • D Milestone Auditing
Explanation Segment Replication provides data redundancy; others serve different purposes.
Q45

You are configuring a new Greenplum database. What happens when you set the statement_timeout parameter too low?

  • A Queries will never execute
  • B Valid queries might fail prematurely
  • C Performance improves under load
  • D No effect on query execution
Explanation Low statement_timeout could cause valid queries to timeout, disrupting normal operations.
Q46

Which service does Greenplum Database primarily use for parallel data processing?

  • A Master and Segmented Data Nodes
  • B Single Node Processing
  • C Monolithic Architecture
  • D Transaction Processing Service
Explanation Greenplum uses master and segment nodes to enable parallel data processing, while the other options do not reflect its architecture.
Q47

A company needs to optimize its query performance in Greenplum. What should be their first step?

  • A Increase memory allocation for segments
  • B Analyze and create appropriate indexes
  • C Upgrade to a larger server instance
  • D Use only primary keys in queries
Explanation Creating appropriate indexes is often the best first step to optimize query performance, rather than just allocating more resources or changing hardware.
Q48

You are configuring data retention for a time-series database in Greenplum. What happens when a retention policy is applied?

  • A All old data is deleted immediately
  • B Incoming data stops being collected
  • C Data older than a set limit is deleted
  • D Retention policies are ignored by default
Explanation A retention policy sets rules to delete data older than a specified limit, while the other options misrepresent how these policies function.
Q49

Which service enables data distribution in Greenplum?

  • A Data distribution service
  • B Data fairness management
  • C Greenplum Query Optimizer
  • D PostgreSQL connection pooler
Explanation The Data distribution service manages how data is distributed across partitions, while the others do not specifically handle distribution.
Q50

A company needs to optimize query execution in Greenplum. What should they consider?

  • A Adding more segments
  • B Increasing the max_connections
  • C Changing query syntax only
  • D Reducing data redundancy
Explanation Adding more segments improves parallel processing, while the other options will not directly optimize query execution.
