Questions and Answers

What is the main advantage of a dual-core design?

  • It enables parallel execution of instructions, potentially doubling performance. (correct)
  • It provides redundancy for high availability in case of hardware failure.
  • It allows for more efficient memory management.
  • It simplifies the operating system design by separating user and kernel modes.
  • In a multicore system, what is the primary difference compared to a multiprocessor system?

  • Multicore systems are used in clustered environments, while multiprocessor systems are not.
  • Multicore systems require special applications to utilize parallelization, while multiprocessor systems do not.
  • Multicore systems are designed for high-performance computing, while multiprocessor systems are not.
  • Multicore systems have multiple processors on a single chip, while multiprocessor systems have separate chips. (correct)
  • What is the primary purpose of a clustered system?

  • To provide high availability and fault tolerance by having redundant nodes. (correct)
  • To simplify memory management by distributing memory across multiple nodes.
  • To improve performance by parallelizing computations across multiple nodes.
  • To enable efficient scheduling of processes across multiple processors.
  • In an asymmetric clustering system, what is the role of the hot standby node?
