Zorluk: ZorCPU Architecture Cooling and Sockets

A systems technician is deploying a specialized edge computing appliance designed to run several client virtual machines. During hardware inspection, the technician observes that the processor is permanently soldered directly onto the system board using an array of solder spheres rather than fitting into a removable socket. When attempting to start 64-bit guest virtual machines, the hypervisor throws an error stating that hardware-assisted virtualization is unavailable. Which of the following correctly identifies this CPU socket/packaging type and the required step to enable hypervisor support?

  1. BGA (Ball Grid Array) packaging; enable hardware virtualization extensions (such as Intel VT-x or AMD-V) in the motherboard's UEFI/BIOS settings.Cevap
  2. B
    LGA (Land Grid Array) packaging; replace the processor with one featuring physical pins to fit the zero insertion force motherboard socket.
  3. C
    PGA (Pin Grid Array) packaging; apply additional thermal paste to prevent CPU thermal throttling from disabling hypervisor execution.
  4. D
    BGA (Ball Grid Array) packaging; upgrade the system power supply unit to meet higher peak wattage requirements for hardware multithreading.

Cevap

The correct option identifies the processor as BGA (Ball Grid Array) packaging and specifies enabling hardware virtualization extensions (Intel VT-x or AMD-V) within the UEFI/BIOS settings.
Processors permanently soldered to the motherboard using solder spheres use Ball Grid Array (BGA) packaging. In addition, hosting 64-bit guest virtual machines requires hardware-assisted virtualization (Intel VT-x or AMD-V), an architectural CPU feature that must be enabled in the system UEFI/BIOS.

Adım Adım Çözüm

1
Analyze the physical CPU mounting description
Processors soldered directly to the motherboard using an array of solder balls use BGA (Ball Grid Array) packaging and cannot be upgraded via a standard socket swap.
BGA is designed for compact and embedded systems where the CPU is permanently attached during manufacturing.
2
Analyze the hypervisor error regarding hardware-assisted virtualization
Virtualization extensions (Intel VT-x / AMD-V) are architectural CPU features supported by modern x86/x64 processors but are often toggled off by default in firmware.
Enabling hardware virtualization in UEFI/BIOS exposes the necessary hardware extensions to the host operating system and hypervisor.
