Motherboards & Processors
A technician upgrades a computer with an LGA processor. Unlike PGA designs, the delicate contact pins are located in this component rather than on the processor itself.
Socket
A gaming content creator wants to record an HDMI signal from a console directly onto a computer. This expansion device accepts the external video signal.
Capture Card
A computer displays no video and fails POST immediately after new memory is installed. Before replacing components, the technician should ______ the memory modules.
RESEAT
A technician finds a legacy Ethernet network using thin coaxial cable, BNC connectors, and terminators at both ends. This Ethernet standard is being used.
10BASE2
A business connects multiple LANs and needs to prevent local broadcast traffic from automatically crossing between them. This device is the best choice.
ROUTER
A computer repeatedly loses its date and time whenever it is unplugged, even though it boots normally when connected to power. This component is the most likely cause.
CMOS Battery
A workstation uses two drives in RAID 0 to maximize performance. One drive fails. Because the array has no redundancy, this happens to the stored data.
LOSS
A technician needs to measure the voltage supplied by a power connector while diagnosing an unstable desktop. This instrument is appropriate.
Multimeter
A switch forwards Ethernet frames to the correct destination port by examining this hardware address.
MAC
A warehouse has several wireless access points. Devices work near each AP but frequently disconnect between coverage areas. This wireless problem is most likely.
WEAK COVERAGE
A legacy motherboard separates its chipset into northbridge and southbridge. This chip traditionally manages high-speed communication among the CPU, RAM, and graphics subsystem.
Northbridge
A technician installs an expansion card that allows a desktop computer to connect to a wired Ethernet network. This card is a ______.
NIC
After installing a dedicated graphics card, the computer boots but the monitor shows no signal. The CPU has no integrated graphics, and the display cable is still connected to the motherboard. The cable should be moved to this component.
GPU
A technician needs a copper Ethernet cable that supports 10 Gbps over a full 100-meter channel. This cable category is the best choice.
CAT 6a
An enterprise needs a dedicated high-speed network that provides centralized block-storage access to multiple servers. This network type is appropriate.
SAN
A computer has an ARM-based processor rather than an x86 processor. ARM is traditionally associated with this instruction-set architecture design philosophy.
RISC
A technician wants to improve the fault tolerance of an array by storing calculated recovery information across multiple drives rather than creating identical copies. This recovery information is called ______.
Parity
A desktop becomes extremely slow. CPU and RAM usage remain normal, but a mechanical drive shows 100% active time with very low throughput. This component should be investigated first.
HDD
A company wants to divide departments into separate logical broadcast domains while using the same managed switch. This feature is required.
VLAN
A campus must connect two buildings using a transmission medium that supports long distances and is immune to electromagnetic interference. This cable medium is preferred.
FIBER
A replacement CPU physically fits the motherboard socket, but the system fails POST. The CPU is functional. The technician should investigate support from this motherboard component.
CHIPSET
A business uses RAID 1. An employee deletes a folder, and the deletion is mirrored to both drives. This independent protection method was missing.
BACKUP
A SATA drive disappears after a technician opens the case for cleaning. The drive works in another computer. The technician should first inspect these physical connections.
SATA CABLES
A computer can communicate with devices on its own subnet but cannot reach devices on another subnet. Its IP address and subnet mask are correct. This setting should be checked first.
DEFAULT GATEWAY
A wireless system uses several antennas to transmit multiple spatial data streams simultaneously, improving throughput. This technology is being used.
MIMO
