Q161

A company needs to enhance data security in a Greenplum cluster. What is a suitable strategy?

  • A Increase hardware resources
  • B Use SSL for connections
  • C Limit self-service access
  • D Disable logging
Explanation Using SSL encrypts data in transit, improving security.
Q162

You are configuring a new Greenplum segment. What would happen if you set the `gp_segment_num` incorrectly?

  • A Improved performance across queries
  • B Data loss during migrations
  • C Inconsistent data distribution
  • D No impact on performance
Explanation Incorrect `gp_segment_num` leads to inconsistent data distribution, which affects query performance.
Q163

What is the primary purpose of a Greenplum Master?

  • A Coordinating query planning and distribution
  • B Storing user data
  • C Handling backup and restore operations
  • D Managing configuration settings
Explanation The Master coordinates the entire database system, optimizing query planning and distribution across segments.
Q164

A company needs high availability for its Greenplum database. Which feature should they implement?

  • A Segment replication
  • B Database compression
  • C Partitioning tables
  • D Read replicas

You are configuring a segment in Greenplum. What happens when a segment is added to a deployment?

  • A Data is redistributed among all segments
  • B All previous data is deleted
  • C Query performance significantly decreases
  • D No change occurs in data distribution
Explanation Adding a segment triggers data redistributing across existing segments to ensure balanced load.
