Question 1

Which RAID level provides disk mirroring?

  1. RAID 0
  2. RAID 1
  3. RAID 5
  4. RAID 6

Correct Answer: 2

Explanation:

RAID 1 provides disk mirroring by maintaining an identical copy of data on two drives. This configuration improves availability because the system can continue operating if one mirrored drive fails. RAID 1 does not provide the same storage efficiency as parity-based RAID because approximately half of the raw capacity is used for redundancy. It is commonly selected when data protection and straightforward recovery are more important than maximizing usable capacity. RAID 0 provides striping without redundancy, while RAID 5 and RAID 6 use distributed parity for fault tolerance across multiple drives.

Question 2

Which HPE technology provides remote server management?

  1. HPE iLO
  2. Smart Array
  3. StoreEasy
  4. OneView

Correct Answer: 1

Explanation:

HPE Integrated Lights-Out, or iLO, provides remote management capabilities for supported HPE servers. Administrators can use iLO to monitor hardware health, access remote consoles, manage power states, and perform various management tasks even when the operating system is unavailable. Because iLO operates independently of the server’s main operating environment, it can remain accessible during many operating-system failures. This makes it useful for remote administration and troubleshooting. HPE OneView serves broader infrastructure-management purposes, while Smart Array refers primarily to HPE storage controller technology.

Question 3

Which memory technology can detect and correct single-bit errors?

  1. SRAM
  2. ECC memory
  3. Flash memory
  4. Cache memory

Correct Answer: 2

Explanation:

ECC, or Error-Correcting Code memory, adds error-detection and correction capabilities to system memory. It can typically detect and correct certain single-bit errors, helping protect servers from memory corruption that could otherwise cause application failures or system instability. ECC memory is especially valuable in enterprise and server environments where reliability and data integrity are important. The memory controller and installed DIMMs must support compatible ECC functionality. Ordinary non-ECC memory does not provide the same level of protection against memory errors, making ECC a common choice for professional server platforms.

Question 4

Which HPE component manages RAID arrays on a ProLiant server?

  1. Smart Array controller
  2. Ethernet adapter
  3. Power supply
  4. Fan module

Correct Answer: 1

Explanation:

An HPE Smart Array controller manages supported RAID configurations and provides storage-controller functionality on HPE ProLiant servers. Depending on the model, the controller can support RAID levels, logical-drive creation, drive management, caching, and fault monitoring. It provides an interface between the server and attached storage devices while presenting configured logical storage to the operating system. Selecting the appropriate controller requires considering drive types, RAID requirements, interface technology, cache features, and supported configurations. Smart Array technology is therefore an important part of HPE server storage architecture.

Question 5

Which storage interface commonly connects enterprise SAS drives?

  1. SATA
  2. SAS
  3. USB
  4. NVMe

Correct Answer: 2

Explanation:

SAS, or Serial Attached SCSI, is an enterprise storage interface designed for reliable communication with storage devices such as SAS hard drives and SSDs. SAS provides features suited to server environments, including dual-port capabilities on supported devices and strong error-handling characteristics. SAS drives are commonly deployed with compatible HPE Smart Array controllers or other enterprise storage controllers. SATA is widely used for consumer and lower-cost storage, while NVMe communicates through PCIe and is designed for high-performance solid-state storage. Choosing the correct interface requires compatibility between drives, backplanes, controllers, and server hardware.

Question 6

Which HPE tool provides centralized infrastructure management?

  1. iLO
  2. OneView
  3. Smart Storage Administrator
  4. Intelligent Provisioning

Correct Answer: 2

Explanation:

HPE OneView provides centralized management for supported HPE infrastructure. It can simplify administration of servers, storage, networking, profiles, firmware, and related infrastructure resources through a unified management platform. Instead of configuring every supported component independently, administrators can use templates and profiles to standardize infrastructure deployment and management. iLO focuses on individual server management, while Smart Storage Administrator is primarily concerned with storage configuration. OneView is therefore useful in environments containing multiple HPE systems where consistent provisioning, monitoring, and lifecycle management are required.

Question 7

Which RAID level uses distributed parity?

  1. RAID 0
  2. RAID 1
  3. RAID 5
  4. RAID 10

Correct Answer: 3

Explanation:

RAID 5 uses distributed parity across the member drives. Data and parity information are spread across the array rather than storing all parity on a single disk. This allows the array to continue operating after one drive failure while providing better usable capacity than full mirroring. RAID 5 requires at least three drives and has write overhead because parity information must be calculated and updated. RAID 0 provides no redundancy, RAID 1 mirrors data, and RAID 10 combines mirroring with striping. RAID selection should consider performance, capacity, and fault-tolerance requirements.

Question 8

Which server component converts AC power into usable DC power?

  1. CPU
  2. Power supply
  3. RAID controller
  4. Network adapter

Correct Answer: 2

Explanation:

The server power supply converts incoming AC electrical power into the DC voltages required by internal components. Modern enterprise servers commonly use power supplies designed for efficiency, monitoring, and redundancy. Many HPE ProLiant systems support multiple power supplies so that a single PSU failure does not necessarily shut down the server. Power supplies must have suitable capacity for the installed processors, memory, storage devices, and expansion hardware. Administrators should also consider input voltage, efficiency ratings, redundancy modes, and available power infrastructure when planning server deployments.

Question 9

Which technology provides high-speed storage access through PCIe?

  1. NVMe
  2. SAS
  3. SATA
  4. SCSI

Correct Answer: 1

Explanation:

NVMe, or Non-Volatile Memory Express, is a storage protocol designed specifically for high-speed nonvolatile memory devices. It commonly communicates through PCIe, providing substantially lower latency and higher parallelism than traditional storage protocols designed around older interfaces. NVMe SSDs are therefore useful in workloads requiring high input/output performance and low latency. HPE servers may support NVMe through specific drive bays, backplanes, controllers, or PCIe configurations depending on the platform. Compatibility should always be verified before deployment because not every server bay or controller supports every NVMe implementation.

Question 10

Which server feature allows failed drives to be replaced while running?

  1. Hot-plug
  2. Cold boot
  3. Virtual memory
  4. Secure boot

Correct Answer: 1

Explanation:

Hot-plug capability allows supported hardware components, such as certain storage drives, to be removed or installed while the server remains powered on. This can reduce service interruptions when replacing a failed drive in a properly configured redundant storage system. Hot-plug operation requires compatible drive bays, backplanes, controllers, and system support. Administrators should follow the platform’s procedures before removing hardware because not every component is safe to remove while powered. When combined with RAID redundancy, hot-plug drives can simplify maintenance and help restore storage protection without shutting down the server.

Question 11

Which processor feature allows multiple threads per CPU core?

  1. Hyper-Threading
  2. Turbo Boost
  3. Virtualization
  4. SpeedStep

Correct Answer: 1

Explanation:

Hyper-Threading is Intel’s simultaneous multithreading technology that allows a physical processor core to present multiple logical processors to the operating system. This enables the processor to work on multiple instruction streams and can improve utilization when workloads contain suitable parallel operations. Hyper-Threading does not double physical processing resources, so performance gains vary according to the workload and system configuration. Server administrators should consider application behavior, licensing, processor architecture, and workload characteristics when evaluating the benefits of simultaneous multithreading.

Question 12

Which HPE utility assists with initial server configuration?

  1. Intelligent Provisioning
  2. iLO Amplifier
  3. OneView
  4. StoreEasy

Correct Answer: 1

Explanation:

HPE Intelligent Provisioning assists with initial server deployment and configuration on supported ProLiant systems. It provides tools for tasks such as operating-system installation, firmware-related operations, hardware configuration, and storage setup. The utility can reduce the amount of manual configuration required during server deployment and provides a guided environment for common provisioning activities. Intelligent Provisioning is closely integrated with HPE server platforms and is separate from OneView, which focuses on centralized infrastructure management. Using supported provisioning tools can improve consistency and simplify repetitive server deployment procedures.

Question 13

Which RAID configuration combines mirroring and striping?

  1. RAID 5
  2. RAID 6
  3. RAID 10
  4. RAID 0

Correct Answer: 3

Explanation:

RAID 10 combines mirroring and striping to provide both redundancy and strong performance. Data is first mirrored across drive pairs and then striped across those mirrored sets. This configuration can continue operating after certain drive failures, provided the failures do not affect both members of the same mirror pair. RAID 10 generally requires at least four drives and sacrifices some raw capacity for redundancy. It is commonly considered for workloads requiring substantial random I/O performance and fault tolerance. Actual behavior depends on controller implementation and drive layout.

Question 14

Which interface is primarily designed for Ethernet networking?

  1. Fibre Channel
  2. SATA
  3. RJ-45 Ethernet
  4. SAS

Correct Answer: 3

Explanation:

RJ-45 Ethernet interfaces are commonly used for wired Ethernet networking in servers and other network devices. Depending on the adapter and cabling, Ethernet interfaces can support different speeds such as 1GbE, 10GbE, 25GbE, or higher. Fibre Channel is primarily associated with storage networking, while SAS and SATA are storage interfaces rather than general-purpose Ethernet networking interfaces. Server network adapters may provide additional features such as VLAN support, hardware offload, teaming, and virtualization capabilities. Selecting the appropriate adapter depends on required bandwidth, topology, transceiver support, and cabling.

Question 15

Which memory module type is commonly used in enterprise servers?

  1. DIMM
  2. SO-DIMM
  3. SIMM
  4. RIMM

Correct Answer: 1

Explanation:

DIMM, or Dual Inline Memory Module, is a common physical memory-module format used in servers. Enterprise server platforms may support specialized DIMM types such as ECC UDIMMs or registered DIMMs depending on the processor platform and system design. Server memory selection must consider capacity, speed, rank configuration, ECC support, and compatibility with the system’s memory architecture. SO-DIMMs are generally associated with compact systems such as laptops, while older module formats such as SIMM are largely obsolete. Using supported memory modules is essential for reliable server operation.

Question 16

Which HPE feature provides remote graphical console access?

  1. iLO Remote Console
  2. Smart Array
  3. OneView Profile
  4. Storage Manager

Correct Answer: 1

Explanation:

HPE iLO Remote Console provides remote graphical access to a supported server’s display and input environment. Administrators can use it to interact with the server as though they were physically connected to a local monitor and keyboard. This is particularly useful during operating-system installation, boot troubleshooting, firmware maintenance, and diagnosing systems that are not responding normally. Because the console operates through iLO, remote access can remain available even when the host operating system has failed. Appropriate iLO configuration and licensing may affect which remote-console capabilities are available.

Question 17

Which storage medium uses flash memory with no moving parts?

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

Correct Answer: 3

Explanation:

A solid-state drive, or SSD, stores data using flash memory rather than spinning magnetic platters. Because SSDs have no mechanical moving parts, they generally provide lower access latency and better resistance to physical vibration than traditional hard disk drives. SSDs are available through interfaces such as SATA, SAS, and NVMe, depending on the device design. Their performance, endurance, capacity, and cost vary according to the underlying flash technology and controller. In server environments, SSDs are often selected for workloads requiring high input/output performance or reduced storage latency.

Question 18

Which component connects a server to a Fibre Channel SAN?

  1. HBA
  2. RAID battery
  3. DIMM
  4. Heat sink

Correct Answer: 1

Explanation:

A Host Bus Adapter, or HBA, provides the server-side interface required to connect to a Fibre Channel storage area network. Fibre Channel HBAs communicate with SAN infrastructure such as Fibre Channel switches and storage arrays. They allow the server operating system to access remote block storage presented through the SAN. HBA configuration can include aspects such as WWNs, zoning relationships, multipathing, and driver support. HBAs differ from ordinary Ethernet network adapters because Fibre Channel is specifically designed for storage networking. Correct compatibility and SAN configuration are essential for reliable storage access.

Question 19

Which server feature reduces downtime after a power supply failure?

  1. Dual power supplies
  2. Single fan
  3. RAID striping
  4. Memory interleaving

Correct Answer: 1

Explanation:

Dual power supplies can provide power redundancy in supported server configurations. When the system is connected to suitable independent power sources, one power supply can fail while the other continues supplying the required power. This can reduce downtime caused by a single PSU failure. For stronger resilience, organizations may connect the power supplies to separate power distribution units or circuits. RAID protects storage, memory interleaving affects memory performance, and fan configurations address cooling rather than direct power redundancy. Proper power planning is therefore an important part of server availability design.

Question 20

Which HPE software helps configure Smart Array storage?

  1. Smart Storage Administrator
  2. Intelligent Provisioning
  3. iLO
  4. OneView

Correct Answer: 1

Explanation:

HPE Smart Storage Administrator, or SSA, provides tools for configuring and managing supported Smart Array controllers and attached storage. Administrators can use it to create or modify logical drives, select RAID configurations, inspect physical drives, and review storage-controller information. SSA can be available through supported operating-system environments or server provisioning tools depending on the platform. Intelligent Provisioning supports broader server deployment tasks, while iLO focuses on remote server management. Using Smart Storage Administrator helps ensure that storage arrays are configured according to performance, capacity, and fault-tolerance requirements.
