Question 341

Which storage feature allows failed data to be reconstructed from parity?

1. Mirroring
2. Striping
3. Spanning
4. Parity protection

Correct Answer: 4

Explanation:

Parity protection stores calculated information that can be used to reconstruct missing data when a qualifying drive fails. RAID levels such as RAID 5 and RAID 6 use parity to provide fault tolerance without requiring complete duplicate copies of all data. Mirroring stores identical copies, striping distributes data, and spanning combines capacity. During a rebuild, the controller uses surviving data and parity information to reconstruct the information that should reside on the replacement or spare drive.

Question 342

What does a processor’s clock speed indicate?

1. Operating frequency
2. Memory capacity
3. RAID width
4. Network throughput

Correct Answer: 1

Explanation:

Processor clock speed represents the operating frequency of the CPU and is commonly expressed in gigahertz. It indicates how rapidly the processor’s clock cycles operate, although it should not be used alone to compare overall processor performance. Architecture, core count, cache, workload, and power behavior also affect performance. Memory capacity describes installed RAM, RAID width concerns storage layout, and network throughput describes data-transfer capability. Processor frequency is therefore one of several important CPU specifications.

Question 343

Which memory characteristic describes the delay before data access begins?

1. Capacity
2. Latency
3. Rank count
4. Channel width

Correct Answer: 2

Explanation:

Memory latency describes the delay associated with accessing data from system memory. Lower latency can contribute to improved responsiveness for workloads that frequently wait for memory operations, although actual performance also depends on memory frequency, channel configuration, processor architecture, and workload behavior. Capacity indicates how much memory is installed, rank count describes memory organization, and channel width concerns the available data-transfer pathway. Administrators should evaluate latency alongside other memory specifications rather than treating it as the only performance factor.

Question 344

Which server feature helps protect against unauthorized chassis opening?

1. RAID controller
2. Memory parity
3. Chassis intrusion detection
4. CPU virtualization

Correct Answer: 3

Explanation:

Chassis intrusion detection can identify or record an event in which the server chassis is opened or otherwise accessed. Depending on the platform, the feature may generate a notification or store an event for later review. This provides an additional physical-security monitoring mechanism. RAID controllers manage storage, memory parity supports data integrity, and CPU virtualization enables virtual-machine capabilities. Chassis intrusion monitoring can be especially useful in environments where physical access to equipment must be controlled and audited.

Question 345

Which storage attribute describes how many writes a solid-state drive can sustain?

1. Capacity
2. Interface speed
3. Endurance rating
4. Queue depth

Correct Answer: 3

Explanation:

An SSD endurance rating indicates how much write activity the drive is designed to withstand over its supported operating life. Endurance may be expressed using measures such as drive writes per day or total bytes written, depending on the product. Capacity describes storage space, interface speed describes communication capability, and queue depth concerns outstanding I/O requests. Matching SSD endurance to workload requirements is important for servers handling sustained write-intensive applications.

Question 346

What does RAID 0 primarily provide?

1. Data redundancy
2. Performance through striping
3. Dual parity
4. Drive mirroring

Correct Answer: 2

Explanation:

RAID 0 distributes data across multiple drives using striping, which can improve aggregate storage performance by allowing operations to use multiple devices. However, RAID 0 provides no redundancy, so the failure of a participating drive can make the array’s data unavailable. RAID 1 provides mirroring, RAID 6 provides dual distributed parity, and other redundant RAID levels offer different protection mechanisms. RAID 0 is therefore generally selected for performance or capacity purposes when fault tolerance is not provided by the array itself.

Question 347

Which interface commonly connects a server to a SATA storage device?

1. SATA
2. PCIe
3. USB
4. VGA

Correct Answer: 1

Explanation:

SATA, or Serial ATA, is an interface designed for connecting compatible storage devices to a system. It has been widely used for hard disk drives, solid-state drives, and optical devices. PCIe provides a high-speed expansion interface, USB connects many types of peripherals, and VGA provides video output. When installing storage hardware, administrators should verify that the server backplane, controller, connectors, and drive type support the intended SATA configuration.

Question 348

What does a storage controller queue manage?

1. Pending I/O requests
2. Processor temperatures
3. Network VLANs
4. Rack dimensions

Correct Answer: 1

Explanation:

A storage controller queue manages pending input/output requests waiting to be processed by the storage subsystem. Efficient queue handling can help organize concurrent operations and maintain effective device utilization. Queue behavior can affect latency and throughput, particularly under demanding workloads. Processor temperatures are monitored through thermal mechanisms, VLANs manage network segmentation, and rack dimensions describe physical installation requirements. Storage administrators may consider queue behavior when troubleshooting performance or evaluating workloads with high levels of concurrent I/O.

Question 349

Which server component provides temporary data storage for active programs?

1. SSD
2. System memory
3. RAID controller
4. Power supply

Correct Answer: 2

Explanation:

System memory provides temporary, high-speed storage for programs and data that are actively being used by the processor. Unlike persistent storage, its contents are normally lost when power is removed. SSDs provide persistent storage, RAID controllers manage storage operations, and power supplies provide electrical power. Adequate memory capacity allows operating systems and applications to keep more active data readily available, reducing dependence on slower storage for frequently accessed working information.

Question 350

Which server bus connects components using high-speed serial lanes?

1. PCIe
2. VGA
3. SATA
4. USB

Correct Answer: 1

Explanation:

PCIe uses high-speed serial lanes to connect supported expansion devices and other platform components. Its scalable lane architecture allows devices to use different numbers of lanes depending on their requirements and the capabilities of the server. VGA is a video interface, SATA is a storage interface, and USB is a general-purpose peripheral interface. PCIe generation and lane configuration both influence the available bandwidth for compatible expansion hardware.

Question 351

What does a server’s memory capacity determine?

1. Number of network ports
2. Available working space
3. RAID parity level
4. Power-supply count

Correct Answer: 2

Explanation:

Memory capacity determines how much working data and program information can be held in system RAM at a given time. Sufficient memory can help operating systems and applications avoid excessive reliance on slower persistent storage. Network-port count depends on installed interfaces, RAID parity level depends on storage configuration, and power-supply count depends on the server’s power architecture. Memory requirements should be evaluated according to application workload, virtualization density, and operating-system needs.

Question 352

Which storage technology uses flash memory without mechanical platters?

1. HDD
2. Tape
3. SSD
4. Optical disc

Correct Answer: 3

Explanation:

An SSD uses flash memory rather than rotating magnetic platters and mechanical read/write heads. This design provides fast access times and eliminates many mechanical components found in traditional hard disk drives. HDDs use rotating magnetic media, tape uses sequential magnetic storage, and optical discs use laser-based media. SSDs are commonly used in enterprise servers where performance, responsiveness, and resistance to mechanical movement are important considerations.

Question 353

What does a server’s chassis provide?

1. Physical enclosure
2. Network routing
3. RAID calculations
4. Memory correction

Correct Answer: 1

Explanation:

The chassis provides the physical enclosure that houses and supports server components. It provides mounting locations for the system board, processors, memory, storage devices, power supplies, cooling components, and expansion hardware. Network routing is performed by network devices or software, RAID calculations are handled by storage controllers or software, and memory correction is supported by compatible memory technology. Chassis design also influences airflow, serviceability, expansion capacity, and physical installation requirements.

Question 354

Which storage device is best suited for long-term sequential archival access?

1. NVMe SSD
2. Tape drive
3. CPU cache
4. DIMM

Correct Answer: 2

Explanation:

Tape drives are commonly associated with long-term archival and backup workloads, particularly where sequential access is acceptable. Tape media can provide high capacity and can be stored offline, helping support long-term retention strategies. NVMe SSDs are optimized for fast random and sequential electronic access, while CPU cache and DIMMs are volatile memory resources rather than archival storage devices. The appropriate archival technology depends on retention requirements, access frequency, recovery objectives, and organizational policies.

Question 355

What does an optical drive use to read compatible media?

1. Magnetic heads
2. Flash cells
3. Laser technology
4. RAID parity

Correct Answer: 3

Explanation:

Optical drives use laser technology to read information encoded on compatible optical media. The laser interacts with the disc surface while the drive interprets the reflected signal as stored data. Magnetic heads are associated with traditional hard disk drives, flash cells are used in solid-state storage, and RAID parity is a storage-redundancy mechanism. Although optical media is less common in modern server environments, optical drives may still be encountered in certain systems or administrative workflows.

Question 356

Which server feature supports direct connection of an external keyboard?

1. SAS port
2. VGA port
3. USB port
4. Fibre Channel port

Correct Answer: 3

Explanation:

A USB port can provide a direct connection for compatible input devices such as a keyboard. Local USB peripherals may be useful during server installation, configuration, or troubleshooting when remote administration is unavailable. SAS is primarily associated with storage connectivity, VGA provides video output, and Fibre Channel is designed for storage networking. Administrators should verify available USB ports and supported device requirements when performing local server maintenance.

Question 357

What does a server’s rack mounting kit primarily provide?

1. Storage redundancy
2. Physical installation hardware
3. Network acceleration
4. Memory expansion

Correct Answer: 2

Explanation:

A rack mounting kit provides the physical hardware required to install a compatible server securely within a rack. Depending on the design, it can include rails, brackets, screws, or other mounting components. Storage redundancy is provided through appropriate RAID configurations, network acceleration depends on network hardware and configuration, and memory expansion requires compatible DIMMs. Using the correct mounting kit helps ensure proper alignment, support, service access, and safe installation.

Question 358

Which component converts electrical signals to optical signals in supported networking equipment?

1. Optical transceiver
2. RAID battery
3. Memory module
4. Power capacitor

Correct Answer: 1

Explanation:

An optical transceiver converts electrical signals into optical signals for transmission over fiber and converts received optical signals back into electrical form. It is commonly used in compatible network interfaces and switches that support fiber-based connectivity. RAID batteries or capacitors protect storage-controller cache, memory modules provide working storage, and power capacitors support electrical functions. Transceiver selection must match the network interface, fiber type, supported speed, connector, and transmission distance.

Question 359

Which storage metric measures input/output operations per second?

1. Throughput
2. Latency
3. IOPS
4. Capacity

Correct Answer: 3

Explanation:

IOPS, or input/output operations per second, measures how many individual storage operations a system can process within a second. It is particularly relevant to workloads involving many small random reads or writes. Throughput measures the amount of data transferred over time, latency measures the delay associated with an operation, and capacity represents available storage space. IOPS should be considered alongside latency and throughput because a single metric does not fully describe storage performance.

Question 360

Which server design feature improves serviceability of replaceable components?

1. Fixed internal cabling
2. Tool-less access
3. Permanent component bonding
4. Sealed drive bays

Correct Answer: 2

Explanation:

Tool-less access can improve serviceability by allowing technicians to remove or install supported components without requiring additional tools for routine maintenance tasks. Enterprise server designs may use latches, release mechanisms, or other tool-less features for selected components. Fixed internal cabling, permanent component bonding, and sealed drive bays generally make servicing more difficult. Serviceability is an important consideration in data centers because faster component replacement can reduce maintenance time and operational disruption.
