                  HPE Network Data Center Professional Architect Sample Questions:

                  1. Can EVPN/VXLAN Fabrics be configured to protect against Layer 2 loops?

                  A) No, AOS-CX does not support such capability.
                  B) Yes, using Spanning-Tree over VXLAN
                  C) Yes, using Loop Protection over VXLAN.
                  D) No, a Layer 2 loop on VXLAN Infrastructure is not possible.


                  2. You have been called in to help design an HPE Aruba Networking CX network solution to connect AI servers to file storage. The solution must support NFS over RDMA and provide 400 GbE links to the edge. The design currently consists of leaf and spine switches, which carry all traffic in VXLAN tunnels. Each switch is a CX 9300-32D switch. What is one correction that you should make to the design?

                  A) Redesign the solution to carry traffic without VXLAN to ensure support for DCB
                  B) Replace the CX 9300-32D switches with CX 9300S switches to ensure support for RoCEv1/v2
                  C) Eliminate the spine to establish a rail-only topology
                  D) Continue to use CX 9300-32D switches for the spine but use CX 9300S switches as leaf switches to optimize costs


                  3. What are important characteristics to mention while discussing possible connections for VMware hosts to server-access-switches?

                  A) VMware ESXi requires the appropriate license to support LACP.
                  B) Only bare metal servers running WindowsServer or Oracle Solaris can use LACP.
                  C) Source MAC Load balancing is always the best option.
                  D) LACP is an old protocol and should no longer be used.


                  4. Refer to the exhibit.

                  You could make a change to the services that will save the customer money without affecting the level of support provided. What is that change?

                  A) Selecting HW Onsite + SW + TechSupp FC 4h OS CDMR
                  B) Selecting SW + TechSupp
                  C) Selecting hardware support only FC 4h OS HW


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

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