An engineer is experiencing reboots on a graphics workstation when rendering complex 3-D models. The workstation is configured with a 115V power supply that is rated at 200W and connected to a UPS. The central processing unit contains 16 hyperthreaded cores, and a discrete graphics solution utilizing an 8-pin power connector is installed in a PCI Express x16 slot. Which of the following indicates where the technician should begin troubleshooting?
The UPS, as 115V is insufficient for the configuration and should be increased to 220V
The power supply, as 200W is sufficient when the GPU is heavily tasked.
The graphics card, as it is the component that triggers the unexpected reboots.
The motherboard, as only standard PCI slots should be used for high-end graphics card, not PCI Express slots.
The power supply, as 200W is insufficient when the GPU is heavily tasked.
Which of the following technologies can allow multiple networks to traverse a switch?
VLAN
VRRP
VPN
DHCP

An end user reports that the time and date on a desktop resets after shutdown, and subsequently, the device reboots. the next day, the desktop does not load the OS and is stuck at a black screen with the following message:
Date/Time Not Set -
Press F1 to Run Setup -
Which of the following would be the BEST action to take next?
Change the motherboard
Reseat the motherboard power connections
Replace the CMOS battery
Restore the BIOS to factory default settings
Replace the CMOS battery
(complementary metal-oxide semiconductor)
n related to a dead or failing CMOS battery, which is used to store the BIOS settings, including the date
and time. Replacing the battery could resolve the issue and allow the desktop to boot into the operating system. If that does not work, then thenext step would be to try restoring the BIOS to factory default settings (Option D). Reseating the motherboard power connections (Option B) or changing the motherboard (Option A) would be a last resort, as it would be more invasive and potentially expensive.
A user reports that a PC occasionally fails to boot. The user reboots the PC, but the performance is degrading. the technician hears a strange, repetitive, ticking noise coming from the PC. Which of the following should the technician do FIRST?
Try to extract data
Reseat the RAM modules
Inspect the fan
Check CD tray
Try to extract data
A technician is upgrading a faulty motherboard that was ordered by an end user for an old, high-end desktop computer. However, the technician is
unable to install the CPU into the socket. Upon closer inspection, the technician notices the pins on the CPU do not line up with the socket. Which
of the following would be the best course of action for the technician to take NEXT?
Try to set as many pins as possible.
Install an adaptor to create a universal socket.
Verity the socket type and manufacturer.
Find a compatible motherboard for the CPU.
Verify the socket type and manufacture.
