                                HPE Network Data Center Professional Architect Sample Questions:

                                1. Waratah Hospital, based in Australia, is planning to move many data center services to new facility. (The remaining legacy data center will not be part of this project.) Waratah Hospital hired an external consultant to assist with the new data center network design.
                                Based on the requirements for the data center network infrastructure, the external consultant has created a high-level design. The below summarizes the content of the design document.
                                Requirements and information:
                                - Six racks in the data center room (single row).
                                - Redundant Top of Rack leaf switches with back-to-front cooling in each rack, providing 10/25 Gbps connectivity to servers, storage, and other devices.
                                - Four 100 GbE uplinks per leaf switch.
                                - The customer requested to install all switch ports facing the back of the rack racks (hot aisle.)
                                - OOB management for servers, storage, and network has to be provided through an external switch with back-to-front cooling. This switch has to be included in the solution. One OOB switch provides connectivity for two racks.
                                - Core equipment for the OOBM network is being reused.
                                - Middle-of-row spine switches.
                                -The data center should connect to the hospital building with links that provide 400 Gbps.
                                - Internet access is provided through an existing firewall cluster with two firewalls, each firewall in one data room. The second firewall is operating in standby mode, VRRP is utilized on the firewalls for failover. The data center network should connect to these firewalls with links that total
                                100 Gbps.
                                - The external link is a dark fiber direct link based on single-mode fiber (OS2). The distance to the main hospital 1.5 KM. The links will terminate on two core switches in the hospital.
                                The customer also requires:
                                - 99.999% uptime for this life-critical environment.
                                - Planned and unplanned downtime has to be minimized.
                                - Software upgrades are only allowed once per year with close to zero downtime.
                                - All life-critical resources are accessed locally, and all resources exist within the hospital campus.
                                - Waratah Hospital requires a highly secure environment for the data center. Encrypted wire speed connectivity between the data room and the hospital is a must-have because the link between the buildings crosses a public road.
                                - Waratah Hospital has a mix of virtualized (vSphere) servers. Nutanix storage, bare metal servers, backup servers and other devices.
                                In the past, the hospital has had a security breach that resulted in data loss, network downtime, and identity theft.
                                Waratah Hospital requires a high availability deployment of Aruba Fabric Composer. How many nodes are supported with the high availability option?

                                A) high availability is not supported
                                B) four nodes
                                C) three nodes
                                D) two nodes


                                2. Your long-time customer has just acquired a company and they are planning on bringing the new data center sites up to their standards. They have asked for a bill of materials given only locations and port counts at the data center sites. What are valid assumptions that should be documented in the proposal? (Choose two.)

                                A) The project will be funded by the capital budget of the acquired company.
                                B) The acquired company's data center racks are sufficient for the new equipment and will be reused.
                                C) The acquired company's data center cooling plant allows for the back-to-front airflow preferred by your customer.
                                D) The acquired company's full-time staff will be converted to contractors.
                                E) The acquired company's IP schema in the existing data centers will be converted to IPv6.


                                3. You are designing an L3 spine and leaf architecture for a customer based on CX 10000 Series switches as leaf switches. The customer has added a requirEMENT that the leaf switches also support servers' iSCSI adapters. You have verified your design also meETS The customer's needs for lossless iSCSI. The customer asks for advice on ensuring that THE East-west firewall permits the iSCSI traffic. What should you explain?

                                A) The customer should place the iSCSI adapters in a PVLAN primary VLAN to ensure trafFIC Is permitted.
                                B) CX 10000 switches do not implement east-west firewall policies on traffic in a no-drop PFC queue.
                                C) The custOMER should place the iSCSI adapters in a PVLAN isolated VLAN to ensure traFFIC is forwarded without disruption from VM traffic.
                                D) Fabric Composer supports VM tag-based Endpoint Groups (EPGs) which will make it easy for the customer to select the iSCSI traffic and permit it.


                                4. You are designing an L3 spine and leaf topology that uses CX switches. Those switches implement EVPN VXLAN. The customer does not require VRF segmentation for any of the data center endpoint traffic. What should you recommend for the VRF in which to place the SVIs for server, VM and other endpoint VLANs?

                                A) Use the default VRF
                                B) Use whichever VRF the switch VXLAN loopback interface is attached to
                                C) Use whichever VRF the switch individual loopback interface is attached to
                                D) Use any VRF name except default


                                5. To secure the network, which feature or capability should be implemented?

                                A) Bluetooth dongle
