    How does the processor design provides boosts in performance?

    • By using SSL transport

    • By denying access to specific hardware resources

    • By ISA cryptographic hardware optimization

    • By allowing the dynamic allocation of hardware resources

    Correct Answer
    A. By allowing the dynamic allocation of hardware resources
    Explanation
    The processor design provides boosts in performance by allowing the dynamic allocation of hardware resources. This means that the processor can allocate resources such as memory, processing power, and cache on-demand, based on the specific needs of the task or program being executed. By dynamically allocating resources, the processor can optimize its performance and efficiency, ensuring that the available hardware resources are utilized effectively to complete tasks quickly and efficiently. This allows for improved overall performance and responsiveness of the system.

    What is the main feature of 'NUMA'?

    • Each CPU or set of CPUs is associated with its own physical memory and devices of another set of CPUs.

    • Each CPU is associated with physical memory and / or devices of some other CPU

    • Each Application or set of Applications is associated with its own physical memory and / or devices

    • Each CPU or set of CPUs is associated with its own physical memory and / or devices

    Correct Answer
    A. Each CPU or set of CPUs is associated with its own physical memory and / or devices
    Explanation
    NUMA stands for Non-Uniform Memory Access. The main feature of NUMA is that each CPU or set of CPUs is associated with its own physical memory and/or devices. This means that each CPU has its own dedicated memory and devices, allowing for faster access and improved performance. This architecture is commonly used in systems with multiple processors or cores to optimize memory access and reduce latency.

    What does 'NUMA' stands for?

    • Non-Utility Memory Allocation

    • Non-Uniform Memory Access

    • Non-Uniform Memory Allocation

    • Non-User Memory Access

    Correct Answer
    A. Non-Uniform Memory Access
    Explanation
    NUMA stands for Non-Uniform Memory Access. This refers to a computer architecture design in which the memory access time is not uniform across all processors. In a NUMA system, each processor has its own local memory, and can access it faster than accessing the memory of other processors. This design allows for better performance and scalability in multi-processor systems, as it reduces the latency caused by accessing remote memory.

    Fill in the blanks.(respectively) Oracle Solaris 11 includes a port of ___________, a tool that detects latency in the system and what the cause is. Through ________, latencies on the system can now be measured and fixed.

    • DTrace & Intel's LatencyPORT

    • Intel's LatencyPORT & DTrace

    • Intel's LatencyTOP & DTrace

    • DTrace & Intel's LatencyTOP

    Correct Answer
    A. Intel's LatencyTOP & DTrace
    Explanation
    Oracle Solaris 11 includes a port of Intel's LatencyTOP, a tool that detects latency in the system and what the cause is. Through DTrace, latencies on the system can now be measured and fixed.

    Oracle Solaris 11 adds support for which of the following processor/servers?

    • SPARC T4 processor

    • SPARC T-Series servers

    • Both of the above

    • None of the above

    Correct Answer
    A. Both of the above
    Explanation
    Oracle Solaris 11 adds support for both the SPARC T4 processor and the SPARC T-Series servers. This means that users of Oracle Solaris 11 can take advantage of the features and capabilities offered by these processors and servers, enhancing their overall computing experience.

    Oracle Solaris 11 provides support for which of the following? (2 correct ansers)

    • ISA cryptographic hardware optimization

    • 4GB page size

    • L2 cache

    • CPU and DRAM performance counter

    Correct Answer(s)
    A. ISA cryptographic hardware optimization
    A. CPU and DRAM performance counter
    Explanation
    Oracle Solaris 11 provides support for ISA cryptographic hardware optimization, which improves the performance of cryptographic operations by offloading them to dedicated hardware. It also supports CPU and DRAM performance counters, which allow users to monitor and analyze the performance of the CPU and memory subsystems. These features enhance the security and performance capabilities of the operating system.

    How to ensure best I/O performance on the systems? (2 correct answers)

    • The processing associated with a device should be performed close to that device

    • The memory used by that device for DMA and PIO should not be allocated close to that device

    • The memory used by that device for DMA and PIO should be allocated close to that device as well

    • The processing associated with a device should be performed in a virtual system.

    Correct Answer(s)
    A. The processing associated with a device should be performed close to that device
    A. The memory used by that device for DMA and PIO should be allocated close to that device as well
    Explanation
    To ensure the best I/O performance on systems, it is important to perform the processing associated with a device close to that device. This reduces latency and improves efficiency by minimizing the distance data needs to travel. Additionally, allocating the memory used by the device for Direct Memory Access (DMA) and Programmed Input/Output (PIO) close to the device further enhances performance. This allows for faster data transfers and reduces the need for data to traverse long distances within the system. By following these practices, the system can optimize I/O performance.

    Which of the following best describes Single-root I/O virtualization (SR-IOV)?

    • Enables application workloads to achieve native I/O performance.

    • SR-IOV delivers superior I/O throughput to guest domains that have SR-IOV on Oracle's SPARC T4 and SPARC T3 platforms

    • SR-IOV delivers superior I/O throughput to guest domains that have SR-IOV on Oracle's SPARC T4 platforms only.

    • Enables system workloads to achieve native I/O performance.

    Correct Answer(s)
    A. Enables application workloads to achieve native I/O performance.
    A. SR-IOV delivers superior I/O throughput to guest domains that have SR-IOV on Oracle's SPARC T4 and SPARC T3 platforms
    Explanation
    The correct answer explains that Single-root I/O virtualization (SR-IOV) enables application workloads to achieve native I/O performance. It also mentions that SR-IOV delivers superior I/O throughput to guest domains that have SR-IOV on Oracle's SPARC T4 and SPARC T3 platforms. This means that SR-IOV allows applications to have direct access to the underlying hardware resources, resulting in improved performance and efficiency.
