Simulation questions- Hardware I

Using the image of the motherboard above, which of the following correctly indicates the circled area?

• Memory slot

• Mini PCIe

• CMOS battery

• Reset jumper

Answer explanation

he area circled indicates the CMOS battery on this motherboard. The CMOS battery is used to keep power to the BIOS configurations, such as the date and time, when the power is removed from a desktop or workstation. For the exam, it is important that you can identify the different parts of the motherboard by sight.

Using the image above, which of the following correctly indicates the port labeled as J?

• USB 3.0

• USB 2.0

• FireWire

• eSATA

Using the image of the motherboard above, which of the following correctly indicates the circled area?

• Fan power

• Reset jumper

• Audio connector

• USB connector

Answer explanation

The area circled indicates the reset jumper on this motherboard. A reset jumper is a small plastic block with a metal connection inside. To reset the motherboard's BIOS, you would connect the jumper over this area to make an electrical connection between the two pins. For the exam, it is important that you can identify the different parts of the motherboard by sight.

Using the image above, which of the following correctly identifies the fiber optic connector shown as Connector C?

• ST

• F

• LC

• SC

Answer explanation

This is an LC connector. A ST, SC, LC, or MTRJ connector is used to terminate a fiber optic cable. An LC, or Lucent connector, is a small form factor connector that combines the transmit and receive cables into a single square, snap-in connector. The F-type connector is used with coaxial cables, not fiber optic cables. An SC, or subscriber connector, is a general-purpose push/pull style connector that has a square, snap-in connector that latches with a simple push-pull motion. SC connectors are widely used in single-mode fiber optic systems. An ST, or straight tip, connector is a quick-release bayonet-style connector that has a long cylindrical connector.

Using the image of the motherboard above, which of the following correctly indicates the circled area?

• AGP

• PCIe x1

• PCIe x4

• PCI

Answer explanation

The area circled indicates the PCIe x1 slots. PCIe (peripheral component interconnect express) is an interface standard for connecting high-speed components. Every desktop PC motherboard has some PCIe slots you can use to add GPUs (video cards or graphics cards), RAID cards, network adapters, Wi-Fi cards, or SSD (solid-state drive) add-on cards. The types of PCIe slots available in your PC will depend on your motherboard and are designated as PCIe x1, x4, x8, and x16. PCIe x1 slots are usually used for external input/output devices such as network interface cards. For the exam, it is important that you can identify the different parts of the motherboard by sight.

Using the image of the motherboard above, which of the following correctly indicates the circled area?

• Memory slot

• CPU power

• Mini PCIe

• CPU slot

Answer explanation

he area circled indicates the CPU slot. This is where the processor is installed into the motherboard. For the exam, it is important that you can identify the different parts of the motherboard by sight.

Using the image above, which of the following correctly identifies the fiber optic connector shown as Connector B?

• SC

• F

• LC

• ST

Answer explanation

his is an ST connector. A ST, SC, LC, or MTRJ connector is used to terminate a fiber optic cable. An ST, or straight tip, connector is a quick-release bayonet-style connector that has a long cylindrical connector. An SC, or subscriber connector, is a general-purpose push/pull style connector that has a square, snap-in connector that latches with a simple push-pull motion. SC connectors are widely used in single-mode fiber optic systems. An LC, or Lucent connector, is a small form factor connector that combines the transmit and receive cables into a single square, snap-in connector.
