Questions and Answers

What is a direct benefit of virtualization in supporting big data stores?

  • Improving data security measures
  • Reducing the cost of purchasing big data storage solutions
  • Enabling real-time data processing
  • Ensuring better scale and performance for MapReduce engines (correct)

How does virtualization help in managing MapReduce tasks more efficiently?

  • Increasing manual intervention for task expansions and contractions
  • Reducing management overhead by allowing parallelization (correct)
  • Enabling each Map and Reduce task to be executed dependently
  • Limiting the scalability of the MapReduce engine

Why is encapsulating the MapReduce engine in a virtual container beneficial?

  • To restrict the flexibility of running tasks
  • To run tasks when needed and increase asset utilization (correct)
  • To decrease asset utilization
  • To enable running tasks only at specific times
