Question 81

Which HPE technology provides automated server firmware and driver inventory?

1. HPE iLO Amplifier Pack
2. Smart Array
3. UEFI Shell
4. Fibre Channel

Correct Answer: 1

Explanation:

HPE iLO Amplifier Pack is designed to help administrators manage and update firmware and drivers across groups of supported HPE ProLiant servers. It can collect inventory information and assist with maintaining consistent firmware levels across larger server environments. Centralized inventory reduces the need to inspect every server individually and can support more organized maintenance planning. Smart Array focuses on storage controllers, UEFI Shell provides a firmware-level command environment, and Fibre Channel provides storage networking. The iLO Amplifier Pack is therefore associated with centralized server firmware and driver management.

Question 82

What is the primary function of a server heat sink?

1. Store firmware
2. Dissipate processor heat
3. Expand memory capacity
4. Filter network traffic

Correct Answer: 2

Explanation:

A heat sink transfers thermal energy away from a processor or other heat-producing component. It increases the surface area available for transferring heat into the surrounding airflow, helping maintain an acceptable operating temperature. Many server cooling designs combine heat sinks with fans and carefully managed airflow. Without adequate heat dissipation, processors can reduce performance through thermal management or potentially experience instability. Heat sinks do not store firmware, expand memory, or filter network traffic. Their role is specifically related to thermal transfer and maintaining safe component operating conditions.

Question 83

Which processor feature allows one physical core to handle multiple instruction streams?

1. Hardware virtualization
2. Turbo frequency
3. Simultaneous multithreading
4. Processor cache

Correct Answer: 3

Explanation:

Simultaneous multithreading allows a physical processor core to present multiple logical execution contexts to the operating system. This can improve utilization of certain processor resources when workloads contain parallel instruction streams. Intel processors commonly implement this concept through Hyper-Threading technology. It does not create additional physical cores, but it can increase the number of logical processors visible to supported operating systems and hypervisors. Hardware virtualization provides processor support for virtual machines, Turbo frequency affects clock speed, and cache stores frequently accessed instructions and data.

Question 84

Which HPE storage component connects multiple drives to a server controller?

1. Drive backplane
2. CPU socket
3. Fan module
4. Network adapter

Correct Answer: 1

Explanation:

A drive backplane provides the physical and electrical interface between installed drives and the server’s storage controller or system architecture. In supported HPE servers, the backplane can simplify drive installation by allowing multiple drives to connect through a common assembly. It may also support hot-plug drive functionality and associated power and signaling connections. A CPU socket holds a processor, a fan module provides cooling, and a network adapter handles network communication. The backplane is therefore an important part of the physical storage path inside a server.

Question 85

Which storage protocol is commonly associated with Fibre Channel host bus adapters?

1. NVMe-oF
2. FC
3. SMB
4. NFS

Correct Answer: 2

Explanation:

Fibre Channel, abbreviated FC, is a specialized networking technology commonly used for enterprise storage connectivity. Fibre Channel Host Bus Adapters provide servers with interfaces for connecting to Fibre Channel fabrics and storage systems. FC environments can provide dedicated storage paths and support features such as zoning and multipathing. SMB and NFS are file-sharing protocols, while NVMe over Fabrics represents a different storage architecture that can use several transport technologies. Fibre Channel remains an important technology for environments requiring dedicated, centralized block-storage connectivity.

Question 86

What does a processor’s clock speed primarily indicate?

1. Number of memory slots
2. Storage capacity
3. Operating frequency
4. Network port count

Correct Answer: 3

Explanation:

Processor clock speed represents the operating frequency at which the processor’s clock cycles occur. It is commonly expressed in units such as gigahertz. Clock speed can influence performance, but it should not be considered in isolation because processor architecture, core count, cache, workload characteristics, and other factors also affect actual application performance. Memory slots, storage capacity, and network port count are independent hardware characteristics. Modern processors can also dynamically adjust frequency according to workload, thermal conditions, power limits, and platform configuration.

Question 87

Which HPE capability can automatically discover supported infrastructure resources?

1. OneView discovery
2. Manual cabling
3. Local formatting
4. Static booting

Correct Answer: 1

Explanation:

HPE OneView includes discovery capabilities that can identify supported infrastructure resources and bring them under centralized management. Discovery helps administrators reduce manual inventory work and establish relationships between managed components. Once resources are discovered and configured, administrators can apply appropriate profiles, templates, and management policies according to the environment. Manual cabling and local formatting are physical or administrative tasks, while static booting concerns startup behavior. Automated discovery is particularly valuable in larger infrastructures where manually documenting every component would be time-consuming.

Question 88

Which memory technology can retain data without continuous power?

1. Volatile DRAM
2. Persistent memory
3. CPU register
4. Cache SRAM

Correct Answer: 2

Explanation:

Persistent memory is designed to retain stored information even when normal system power is removed, depending on the specific technology and platform implementation. This characteristic distinguishes it from conventional volatile DRAM, whose contents are normally lost when power is removed. Persistent memory can provide storage-like persistence while maintaining memory-oriented access characteristics for supported applications. CPU registers and cache SRAM are volatile processor resources. Persistent memory configurations require compatible hardware, firmware, and operating-system support, so administrators should verify platform requirements before deployment.

Question 89

Which rack feature is used to organize and secure server cabling?

1. Cable management arm
2. CPU retainer
3. DIMM latch
4. Drive spacer

Correct Answer: 1

Explanation:

A cable management arm helps organize cables connected to a rack-mounted server while allowing the equipment to move on its rails for service. It can reduce cable strain, prevent excessive bending, and keep connections more orderly behind the server. Proper cable management also helps preserve airflow and makes maintenance easier. A CPU retainer secures processor components, a DIMM latch holds memory modules, and a drive spacer occupies unused drive-bay space. Cable management hardware is therefore mainly concerned with physical organization and serviceability.

Question 90

What does processor Turbo Boost primarily adjust?

1. Disk queue depth
2. Network duplex mode
3. CPU operating frequency
4. Memory slot count

Correct Answer: 3

Explanation:

Turbo Boost dynamically increases processor operating frequency above the base frequency when supported workload, power, temperature, and platform conditions allow it. This can improve performance for workloads that benefit from temporarily higher processor frequency. The exact behavior depends on processor generation and system configuration. Turbo technology does not change disk queue depth, network duplex settings, or the number of installed memory slots. Administrators should understand that sustained maximum turbo frequency depends on thermal and power limits rather than being guaranteed at all times.

Question 91

Which HPE security technology can help verify platform integrity during startup?

1. Trusted Platform Module
2. Storage cache
3. Network teaming
4. Drive carrier

Correct Answer: 1

Explanation:

A Trusted Platform Module can participate in platform integrity and measured-boot processes by securely storing cryptographic information and recording measurements associated with startup components. This allows supported security software to evaluate whether important portions of the boot environment have changed unexpectedly. TPM technology can also support secure key storage and other cryptographic operations. Storage cache improves I/O performance, network teaming provides connectivity resilience, and drive carriers provide physical drive mounting. TPM-based security is therefore closely associated with establishing trust in the server platform.

Question 92

Which HPE server feature allows administrators to view hardware status without entering the operating system?

1. iLO health monitoring
2. SMB file sharing
3. NFS export
4. DNS caching

Correct Answer: 1

Explanation:

HPE iLO provides out-of-band management, allowing administrators to access server hardware information independently of the installed operating system. Through iLO, administrators can review hardware health, power state, temperature information, storage status, and other supported management details. This is useful when the operating system is unavailable or experiencing problems. SMB provides network file sharing, NFS provides file access across supported networks, and DNS caching concerns name resolution. Out-of-band management therefore gives administrators a separate management path for monitoring and maintaining the physical server.

Question 93

Which server component distributes power from a power supply to internal hardware?

1. Memory controller
2. Power distribution board
3. RAID cache
4. Network backplane

Correct Answer: 2

Explanation:

A power distribution board routes electrical power from the server’s power-input or power-supply system to the internal components that require it. It forms part of the server’s internal power architecture and helps deliver appropriate electrical connections to processors, storage devices, fans, and other hardware. The memory controller manages memory communication, RAID cache supports storage operations, and a network backplane handles networking-related connections. Power distribution components are important when servicing servers because improper handling of internal power connections can damage equipment or create safety hazards.

Question 94

What is the main purpose of memory scrubbing?

1. Detect and correct memory errors
2. Increase network bandwidth
3. Expand disk partitions
4. Modify processor frequency

Correct Answer: 1

Explanation:

Memory scrubbing is a reliability mechanism that periodically checks memory contents for certain correctable errors and can repair them before they accumulate into more serious problems. It works together with supported memory error-correction capabilities to improve system reliability. Detecting and correcting errors proactively can reduce the chance of an uncorrectable error causing a system failure. Memory scrubbing does not increase network bandwidth, expand disk partitions, or modify processor frequency. Its primary purpose is maintaining memory integrity and reducing the impact of correctable memory faults.

Question 95

Which interface is commonly used to connect an HPE server to a management network?

1. Dedicated iLO port
2. SAS connector
3. VGA output
4. Drive interface

Correct Answer: 1

Explanation:

Many HPE ProLiant servers provide a dedicated iLO network interface that allows administrators to connect the integrated management controller to a management network. This provides an independent path for remote monitoring, configuration, console access, power control, and other supported management functions. The dedicated management connection can remain available even when the operating system or production network is unavailable. SAS connectors are used for storage, VGA provides display output, and drive interfaces connect storage devices. Separating management traffic can also help improve administrative security and network organization.

Question 96

Which storage method provides file access through a shared network directory?

1. Block storage
2. File-level storage
3. Raw disk mapping
4. Local volume access

Correct Answer: 2

Explanation:

File-level storage provides access to files and directories through a shared network filesystem. Clients communicate with the storage service using protocols such as SMB or NFS and work with individual files rather than directly managing raw storage blocks. This model is useful for shared documents, application data, and collaborative file repositories. Block storage instead presents storage resources as block devices, which can then be formatted and managed by the host. File-level access therefore emphasizes shared directory and file operations rather than direct block-device management.

Question 97

Which HPE component can provide a physical connection for additional PCIe expansion devices?

1. Riser card
2. Heat spreader
3. Fan cage
4. Drive bezel

Correct Answer: 1

Explanation:

A PCIe riser card provides expansion connectivity in server designs where additional PCIe cards need to be installed in a different physical orientation or location. Riser assemblies are common in rack servers because they allow expansion slots to fit within compact chassis designs. Supported risers can expose multiple PCIe slots for network adapters, storage controllers, accelerators, or other expansion hardware. Heat spreaders manage thermal transfer, fan cages support cooling components, and drive bezels cover storage bays. The appropriate riser depends on the server model and supported PCIe configuration.

Question 98

Which network feature can separate traffic into logical broadcast domains?

1. VLAN
2. RAID
3. NUMA
4. TPM

Correct Answer: 1

Explanation:

A Virtual LAN, or VLAN, logically separates network traffic into distinct broadcast domains even when devices share the same physical switching infrastructure. VLANs can improve network organization, segmentation, and traffic management by separating systems according to function or security requirements. Switches and network adapters must support the required VLAN configuration. RAID provides storage redundancy or performance capabilities, NUMA describes processor and memory topology, and TPM provides hardware-based security functions. VLAN segmentation is therefore a networking mechanism rather than a storage, processor, or security-module feature.

Question 99

Which HPE management interface can expose server information through a REST-based API?

1. HPE RESTful Interface Tool
2. RAID controller firmware
3. Memory diagnostics
4. Power switch

Correct Answer: 1

Explanation:

The HPE RESTful Interface Tool provides programmatic access to supported server configuration and management capabilities through REST-based interfaces. This allows administrators and automation systems to perform management tasks without relying exclusively on manual graphical interfaces. REST-based management is useful for scripting, repeatable provisioning, configuration automation, and integration with broader infrastructure-management workflows. RAID controller firmware focuses on storage-controller operation, memory diagnostics focus on hardware testing, and a power switch controls electrical state. Programmatic management can significantly reduce repetitive manual configuration in larger environments.

Question 100

Which server design element helps prevent electromagnetic interference from escaping the chassis?

1. Chassis shielding
2. Memory interleaving
3. Storage striping
4. CPU virtualization

Correct Answer: 1

Explanation:

Chassis shielding helps contain electromagnetic emissions produced by electronic components inside a server and can also reduce the effect of external electromagnetic interference on sensitive circuitry. Proper chassis construction, grounding, shielding materials, and cable design contribute to electromagnetic compatibility. Memory interleaving improves memory bandwidth, storage striping distributes data across drives, and CPU virtualization provides hardware support for virtualized workloads. Electromagnetic compatibility is important in dense data-center environments because numerous electronic systems may operate close to one another and must function without causing unacceptable interference.
