HPE0-V27 HPE Edge-to-Cloud Solutions Exam Practice Test

Answer : A

Answer : B

The technology that should be recommended to the customer for machine learning that requires low latencies and high transfer rates is RoCE. RoCE stands for RDMA over Converged Ethernet, which is a protocol that enables Remote Direct Memory Access (RDMA) over Ethernet networks. RDMA is a technology that allows direct memory access from one computer to another without involving the operating system or the CPU, thus reducing the overhead and latency of data transfers. RoCE offers the following benefits for machine learning environments:

It supports high bandwidth and low latency data transfers, which are essential for machine learning applications that involve large amounts of data and complex computations12.

It improves the efficiency and scalability of the network, as it reduces the CPU utilization and the network congestion caused by data transfers13.

It leverages the existing Ethernet infrastructure, which is widely deployed and cost-effective, and does not require any specialized hardware or software14.

It is compatible with HPE solutions, such as HPE Alletra, HPE Synergy, and HPE Apollo, which support RoCE and provide optimized infrastructure and management services for machine learning workloads567.

The other options are not suitable for machine learning that requires low latencies and high transfer rates because:

A) SCSI stands for Small Computer System Interface, which is a set of standards for connecting and transferring data between devices, such as hard disks, tape drives, scanners, and printers.SCSI is mainly used for storage devices and does not support RDMA or Ethernet networks8.

C) SMB stands for Server Message Block, which is a network file sharing protocol that allows access to files, printers, and other resources on a network.SMB is mainly used for file sharing and does not support RDMA or Ethernet networks9.

D) NFS stands for Network File System, which is a distributed file system protocol that allows access to files over a network.NFS is mainly used for file sharing and does not support RDMA or Ethernet networks10.

Answer : A, D

When generating a customer HPE GreenLake proposal, you need to submit the following mandatory items to HPE for quoting:

Start Bill of Materials: This is a document that lists the initial hardware and software components, quantities, and prices that are required for the HPE GreenLake solution. It also includes the service level, the billing unit, the minimum and maximum capacity, and the buffer size. The Start Bill of Materials helps HPE to calculate the monthly fee and the buffer charge for the customer.

Completed Order Checklist: This is a document that contains the essential information and documents that are needed to process the HPE GreenLake order. It includes the customer name, address, contact details, legal entity, billing frequency, payment method, contract term, start date, end date, and signature. It also includes the attachments such as the Start Bill of Materials, the End Bill of Materials, the Statement of Work, the Credit Check Form, and the Customer Acceptance Form.

The other items are not mandatory for the initial proposal, but they may be required later in the order process:

End Bill of Materials: This is a document that lists the final hardware and software components, quantities, and prices that are delivered and installed for the HPE GreenLake solution. It may differ from the Start Bill of Materials due to changes in the customer requirements, availability, or pricing. The End Bill of Materials helps HPE to reconcile the actual usage and billing with the customer.

Signed Statement of Work: This is a document that defines the scope, deliverables, responsibilities, and terms and conditions of the HPE GreenLake service. It also includes the service level agreement, the service description, the service activation, the service management, the service reporting, and the service termination. The Statement of Work must be signed by both HPE and the customer before the service can start.

Credit Check Form: This is a document that authorizes HPE to perform a credit check on the customer to assess their financial stability and creditworthiness. The credit check helps HPE to determine the payment terms and conditions for the HPE GreenLake service.

Answer : C

OCA (One Config Advanced) and SSET (Solution Sizer and Estimator Tool) are both tools that help design and configure HPE solutions. OCA is a web-based tool that allows users to create and validate configurations for HPE servers, storage, and networking products. SSET is a tool that helps users estimate the power, cooling, and space requirements for HPE solutions. SSET also provides recommendations for rack and power distribution units (PDUs). Compared to OCA, SSET requires an additional datacenter characteristic to configure a solution: the input voltage. This is because the input voltage affects the power consumption and efficiency of the solution. The input voltage can be either single-phase or three-phase, and it can vary depending on the country and region. SSET allows users to select the input voltage from a list of predefined values or enter a custom value. OCA does not require the input voltage as an input parameter, as it only focuses on the product configuration and compatibility.Reference:Edge to Cloud Solutions: Engineered Experiences to Unlock Your Full Potential, Chapter 5: Next Generation Compute, Storage, and Integrated Data Solutions, page 97. HPE SSET User Guide, page 7.

HPE's disaggregated hyperconverged infrastructure (dHCI) is a solution that combines the simplicity and ease-of-use of HCI with the flexibility and scalability of disaggregated architecture. It consists of three main components: compute nodes, storage nodes, and networking. The compute nodes are HPE ProLiant servers that run the applications and virtual machines. The storage nodes are HPE Alletra 6000 arrays that provide storage capacity and data services. The networking is the fabric that connects the compute and storage nodes, providing high-speed data transfer and management.

The HPE Alletra 6000 arrays can be connected to the compute nodes using either iSCSI or FC protocols, depending on the customer's preference and existing infrastructure. Therefore, both D and B are valid options for the storage nodes. However, the question asks for three components, so only one of them can be chosen. Since the question does not specify the protocol, we can assume that either one is acceptable. For simplicity, we choose D as the answer.

The HPE ProLiant servers can be either rack-mounted or blade servers, depending on the customer's needs and space constraints. Therefore, both F and C are valid options for the compute nodes. However, the question asks for three components, so only one of them can be chosen. Since the question does not specify the form factor, we can assume that either one is acceptable. For simplicity, we choose F as the answer.

The networking component can be any of the approved options for storage switches, including HPE Aruba, Cisco, Mellanox, and others. Therefore, E is a valid option for the networking component. A is not a valid option, because HPE B-series switches are not compatible with HPE Alletra 6000 arrays.

Therefore, the correct answer is D, E, F.Reference:
