HPE server hardware configuration. The exam is designed to test the candidate's knowledge and skills related to HPE ProLiant server products, including the Gen10 and Gen9 families. It covers topics such as server architecture, installation, configuration, management, maintenance, and troubleshooting. The exam is intended for HPE partners, customers, and employees who are involved in the design, deployment, and support of HPE server solutions.

Explanation:
The DL20 Gen10 Plus is a flexible and affordable 15" deep server supporting the latest Intel XEON E processors12.
The DL180 Gen10 is a secure and cost effective IP 2U server delivering flexible storage capacity, delivering a high core count, and a large memory footprint12.
The DL345 is a high-density, four-socket server with high performance, scalability and reliability, all in a 2U chassis for business-critical computing performance12.
The DL560 is a secure 2P 2U server delivering world-class compelling performance with the right balance of expandability and scalability12.

Explanation:
NAS: c) Sharing files over industry standard protocols such as NFSv4 or SMB.
SAN: a) Block access using a FC protocol. or b) Block access using FCoE protocol or d) Block access using the iSCSI protocol.
According to the HPE website, NAS stands for Network Attached Storage and is a storage system that provides file-level access to data over a network. NAS devices use protocols such as NFSv4 or SMB to share files with clients. NAS devices typically have their own file system and operating system and can support multiple users and applications.
SAN stands for Storage Area Network and is a network that provides block-level access to data over a dedicated network. SAN devices use protocols such as FC, FCoE, or iSCSI to transfer blocks of data to servers. SAN devices do not have their own file system and rely on the servers to manage the data. SAN devices typically provide high performance and availability for mission-critical applications.

HPE SimpliVity: This is an ideal solution for small IT teams as it integrates compute, storage, and networking into a single hyper-converged infrastructure (HCI) platform. It simplifies management and scales linearly, making it suitable for environments with predictable workloads and growth requirements that depend on cash flow.

According to Simplilearn, big data storage is a new technology that allows you to store large amounts of data that exceed the capacity of typical database software tools1. Big data storage can handle various types of data, such as structured, unstructured, or semi-structured data, and provide fast and scalable access to it1.
