Questions and Answers

What is the main characteristic of a multi-tenant database system?

  • It allows multiple tenants to share a single database instance (correct)
  • It provides isolated views of the data for each tenant
  • It stores each tenant's data in a separate database instance
  • It requires dedicated hardware resources for each tenant

    • In a shared-nothing architecture, what type of resources does each tenant have?

  • Shared hardware resources
  • Limited hardware resources
  • Virtualized hardware resources
  • Dedicated hardware resources (correct)

    • What is the primary use case for a shared-nothing architecture in multi-tenant database systems?

  • Data warehousing applications with heavy analytics requirements
  • Low-cost applications not requiring much processing power or isolation
  • High-performance applications requiring processing power and isolation (correct)
  • Transactional applications with frequent data updates

    • What is the key advantage of using multi-tenant database systems for organizations?
