Which component executes instructions and processes data in a computer?
Power Supply Unit (PSU)
Graphics Processing Unit (GPU)
Central Processing Unit (CPU)
Network Interface Card (NIC)
The CPU is the primary processor responsible for executing instructions and performing calculations. GPUs specialize in parallel tasks like graphics, while NICs handle network traffic and PSUs supply power.
What type of memory is volatile and temporarily holds data for quick access by the CPU?
Hard Disk Drive (HDD)
Random Access Memory (RAM)
Read-Only Memory (ROM)
Solid-State Drive (SSD)
RAM is volatile memory that the CPU uses for short-term data storage and quick access. ROM is non-volatile, and HDDs/SSDs are persistent storage devices.
Which storage device uses spinning magnetic platters to store data?
Solid-State Drive (SSD)
Hard Disk Drive (HDD)
Dynamic RAM (DRAM)
NVMe Drive
HDDs store data on spinning magnetic platters. SSDs and NVMe drives use flash memory, and DRAM is a form of volatile system memory.
What expansion slot is most commonly used for modern discrete graphics cards?
PCI Express x16
PCI
AGP
ISA
PCI Express x16 slots provide the bandwidth required by modern graphics cards. AGP, PCI, and ISA are older or lower-bandwidth interfaces.
In IT hardware, what does PSU stand for?
Network Print Server Unit
Power Supply Unit
Processor Synchronization Unit
Peripheral Support Unit
PSU stands for Power Supply Unit, which converts AC power to DC voltages for computer components. The other options are not standard hardware terms.
For a virtualization server requiring error-checking memory, which RAM type is most appropriate?
DDR3 SDRAM
LPDDR4
DDR4 ECC
DDR4 non-ECC
DDR4 ECC memory includes error-correcting code to detect and correct data corruption, which is critical for virtualization stability. Non-ECC RAM and other types lack this feature.
Which performance metric best indicates random read/write performance of a storage device?
Form factor
Sequential throughput (MB/s)
Latency in milliseconds
Input/Output Operations Per Second (IOPS)
IOPS measures how many random read/write operations a device can handle per second. Sequential throughput measures large-block transfer speed, not random access performance.
Which interface allows transmission of both high-resolution video and audio over a single cable?
DisplayPort
Composite Video
DVI
VGA
DisplayPort carries digital video and audio signals in a single cable at very high resolutions. VGA and DVI are analog or limited, and composite video is low quality.
What interface is used for legacy serial communication in point-of-sale printer integration?
Bluetooth
RS-232
USB 3.0
Ethernet
RS-232 is a standard for serial communication often used in legacy and POS printers. USB, Ethernet, and Bluetooth are modern alternatives not classified as RS-232 serial interfaces.
When selecting a network switch for Power over Ethernet (PoE) IP cameras, which feature is essential?
Fiber uplink only
PoE support
Layer 3 routing
Unmanaged design
PoE support supplies power over Ethernet cables directly to IP cameras. Layer 3, fiber uplinks, or unmanaged design do not ensure power delivery.
Between a 4-core 3.5 GHz CPU and a 6-core 3.0 GHz CPU, which offers better multithreaded performance?
Performance depends only on cache size
6-core 3.0 GHz CPU
4-core 3.5 GHz CPU
They perform equally
More cores generally yield higher multithreaded throughput even at slightly lower clock speeds. Cache size affects performance but is not the only factor.
A laptop with a 2.5-inch drive bay needs a replacement SSD. Which form factor is most compatible?
PCIe add-in SSD
External USB SSD
M.2 NVMe SSD
2.5-inch SATA SSD
A 2.5-inch SATA SSD fits directly into a 2.5-inch drive bay. M.2 and PCIe add-in cards require different slots and external USB SSDs do not mount internally.
Which RAID level mirrors data across two disks for redundancy and read performance?
RAID 0
JBOD
RAID 5
RAID 1
RAID 1 duplicates data on two drives, providing fault tolerance and improved read speed. RAID 0 stripes data without redundancy, and RAID 5 requires at least three disks.
Which cabling choice is best for future-proofing gigabit Ethernet with minimal interference?
Coaxial
Fiber at 100 Mbps
Cat6
Cat5
Cat6 cables support gigabit Ethernet with better crosstalk protection and headroom for 10 Gbps over short runs. Cat5 is limited to 1 Gbps, and coax/fiber at 100 Mbps underperform.
If frequent random file access is required, which storage choice is optimal?
Tape drive
SSD
Optical disc
HDD
SSDs have near-zero seek times and high IOPS, making them ideal for random access. HDDs, optical discs, and tape drives have slower access latencies.
Between a CPU with 8 cores but no SMT and one with 6 cores and SMT, which is superior for virtualization?
They are equal
6-core CPU with SMT
Depends solely on cache size
8-core CPU without SMT
SMT (simultaneous multithreading) enables more virtual threads, making a 6-core with SMT better for virtualization than 8 true cores without SMT. Core count alone isn't the only factor.
For high-IOPS and redundancy in a data center, which storage configuration is best?
RAID 10 over NVMe drives
RAID 6 over SATA SSDs
JBOD with NVMe
RAID 5 over HDDs
RAID 10 combines mirroring and striping for redundancy and performance, and NVMe drives deliver very high IOPS. RAID 5/6 and JBOD do not match that IOPS and redundancy level.
Which switch type is required when you need VLAN segmentation and traffic shaping in a corporate LAN?
Unmanaged switch
Hub
Repeater
Managed switch
Managed switches support VLANs and QoS traffic shaping. Unmanaged switches, hubs, and repeaters lack these advanced configuration capabilities.
To connect multiple USB-C devices needing 60 W power delivery and high-speed data, which hub is suitable?
USB-A 2.0 hub
Bluetooth KVM switch
Thunderbolt dock
Passive USB-C to USB-A adapter
A Thunderbolt dock can provide up to 100 W power delivery and multi-gigabit data throughput. USB-A hubs and passive adapters can't handle that power or bandwidth.
Which benchmark metric is most reliable for single-threaded CPU performance comparison?
Cinebench single-core score
CPU TDP
Cinebench multi-core score
Base clock frequency
Cinebench single-core score reflects real-world single-threaded performance. Multi-core score measures overall throughput, and TDP or clock speed alone don't capture IPC differences.
