                  HPE Network Data Center Professional Architect Sample Questions:

                  1. You are replacing the access layer of a customer data center network that uses VMware NSX.
                  The customer has identified several subnets outside the VMware platform to which the customer would like to add overlay routing. What high-level plan works for this customer?

                  A) Proposing CX switches and a Fabric Composer plug-in to Morpheus VM Essentials, which will create an integrated overlay fabric for all subnets
                  B) Proposing CX switches and a Fabric Composer plug-in. which will enable the CX switches to add the subnets in question to the same overlay used by NSX
                  C) Proposing CX switches that use EVPN VXLAN to provide a separate overlay fabric for the subnets in question
                  D) Proposing CX switches, which will integrate with NSX to provide the desired functionality provided that the customer also add NSX licenses


                  2. 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.
                  Refer to the scenario. You have learned that the customer needs to extend two VRFs between the new data center facility and the hospital. To meet with the requirements of the scenario and general best practices, what should you recommend for connecting border leaf switches to the hospital core?

                  A) 4x 100 Gbps links that are routed only ports. Border leaf switch 1 has two ports that connect to hospital core switch 1. Border leaf switch 2 has two ports that connect to hospital core switch 2.
                  B) 8x 50Gbps links that establish two full meshes between two border leaf switches and two hospital core switches. The 4 links that connect to the hospital core 1 in one VSX LAG, and the other 4 links are in another VSX LAG.
                  C) 8x 50Gbps links that are all routed only ports (ROPs). These ports establish two full meshes between two border leaf switches and two hospital core switches.
                  D) 4x 100 Gbps links, establishing a full mesh between two border leaf switches and two hospital core switches. Each link should have two subinterfaces acting as routed only ports.

                  Refer to the scenario. Given the requirement for integration with ServiceNow, which CX feature provides automatic ticket creation in ServiceNow based on network events?

                  A) SOAP
                  B) probe
                  C) REST API
                  D) NAE


                  4. A customer currently has a data center network that uses CX switches and Pensando to implement east-west firewalling. The data center is currently highly virtualized with VMware.
                  However, the customer is considering migrating some workloads to HPE VMs running on HPE Morpheus VM Essentials (VME). What should you explain?

                  A) The customer should use the VME DSS plug-in to utilize the full firewall features, including microsegmentation.
                  B) The customer will not be able to implement the east-west firewall policies for traffic originating from the HPE VMs, but can continue to use the1nnatingcies to secure other data center traffic.
                  C) The customer should purchase the HPE Morpheus Enterprise license to enable support for PVLAN and the full firewall features, including microsegmentation.
                  D) The customer will not be able to implement microsegmentation between the HPE VMs on the same subnet, but can implement segmentation between VMs on different subnets.
