HP HPE0-V27 Exam With Confidence Using Practice Dumps

According to the Advanced HPE Edge-to-Cloud Solutions, page 98, the following matches are correct:

• Communicates key parameters between DCB-capable devices. = DCBX
• Enables control over how much bandwidth can be used over a conventional link. = ETS
• Helps to ensure that Ethernet can provide the lossless frame delivery of FCoE. = PFC
• Provides instructions to CNA about application-to-CoS mapping. = APP

• DCBX: Data Center Bridging Exchange Protocol. It is a protocol that enables the exchange of configuration and capability information between DCB-capable devices, such as switches and servers. It allows the devices to negotiate and agree on the parameters for the DCB features, such as ETS, PFC, and APP1.
• ETS: Enhanced Transmission Selection. It is a feature that enables the allocation of bandwidth to different traffic classes on a link, based on the priority and the service level agreement. It allows the devices to control how much bandwidth can be used by each traffic class, and to avoid congestion and contention on the link1.
• PFC: Priority-based Flow Control. It is a feature that enables the pause and resume of traffic on a link, based on the priority and the buffer availability. It allows the devices to prevent the loss of frames due to buffer overflow, and to ensure the lossless delivery of FCoE traffic, which requires reliable and in-order transmission1.
• APP: Application Priority. It is a feature that enables the mapping of applications to traffic classes on a link, based on the priority and the quality of service. It allows the devices to instruct the Converged Network Adapter (CNA) about which traffic class to use for each application, and to optimize the performance and efficiency of the traffic1.

• Scales up and down to meet workload requirements. = Both
• Can include infrastructure, colocation, power and cooling in a single bill. = HPE GreenLake
• Customer retains ownership of the assets. = Customer
• HPE retains ownership of the assets. = HPE GreenLake
• Customer can add HPE GreenLake Management Service. = HPE GreenLake

• Both: Both customer and HPE GreenLake solutions can scale up and down to meet workload requirements, depending on the type of solution and the contract terms. For example, a customer can purchase a scalable solution, such as HPE Synergy or HPE SimpliVity, and add or remove resources as needed. Alternatively, a customer can use HPE GreenLake, which offers a pay-per-use model, and adjust the capacity and performance on demand.
• HPE GreenLake: HPE GreenLake is a consumption-based model where the customer pays only for the resources they use, on a monthly basis. HPE owns the assets and provides them as a service to the customer, along with the necessary support, management, and optimization. HPE GreenLake can include infrastructure, colocation, power and cooling in a single bill, depending on the customer’s needs and preferences. HPE GreenLake also allows the customer to add HPE GreenLake Management Service, which is a cloud-native platform that provides a unified and consistent experience for managing and optimizing HPE’s edge-to-cloud solutions.
• Customer: Customer is a traditional acquisition model where the customer pays upfront for the hardware, software, and services they need. The customer owns the assets and is responsible for their maintenance, management, and upgrade. This model gives the customer more control, security, and customization over their assets, but it also requires more investment, maintenance, and expertise.

A physical site survey is a detailed inspection and assessment of a plot of land or a facility where work is proposed, to gather information for a design or an estimate to complete the initial tasks required for an outdoor or indoor activity12. It can determine a precise location, access, best orientation for the site and the location of obstacles3. A physical site survey is important for any architectural or engineering project, as it provides critical information that affects everything from project planning to execution2.

One of the areas where a physical site survey is required is the datacenter, where HPE Edge-to-Cloud Solutions can be deployed to provide a hybrid cloud operating model across all workloads and data4. A datacenter is a facility that houses computing and networking equipment, as well aspower, cooling, security, and fire suppression systems5. A physical site survey of a datacenter should gather information such as:

• Datacenter dimensions: The size and shape of the datacenter, including the floor area, ceiling height, and available space for racks, cabinets, and equipment. This information is essential for determining the optimal layout and design of the datacenter, as well as the capacity and scalability of the infrastructure5.
• Fire suppression capabilities: The type and availability of fire suppression systems in the datacenter, such as sprinklers, gas, or foam. This information is important for ensuring the safety and reliability of the datacenter, as well as complying with the fire codes and regulations5.

Other information that may be gathered during a physical site survey of a datacenter include:

• Power and cooling requirements: The amount and quality of power and cooling available in the datacenter, as well as the backup and redundancy options. This information is crucial for ensuring the performance and availability of the datacenter, as well as minimizing the energy consumption and costs5.
• Network connectivity and security: The type and speed of network connections and services available in the datacenter, as well as the security measures and policies in place. This information is vital for ensuring the connectivity and security of the datacenter, as well as supporting the edge-to-cloud solutions and services5.

The other options, such as existing VLANs, current patch levels, and existing disk capacity, are not information that should be gathered during a physical site survey, as they are more relevant for a logical or technical site survey. A logical or technical site survey is a different type of site survey that focuses on the existing or planned configuration and functionality of the IT systems and devices in a site, such as servers, storage, switches, routers, firewalls, and software. A logical or technical site survey is usually performed after a physical site survey, and may require additional tools and methods, such as network analyzers, ping tests, traceroute, and SNMP.
