                  HPE Network Data Center Professional Architect Exam Sample Questions (Q30-Q35):

                  NEW QUESTION # 30
                  Which of the following best describes the purpose of a "risk register" in a data center network design project?

                  Answer: D

                  Explanation:
                  A risk register formally tracks identified project and technical risks along with their likelihood, impact, and mitigation plans, helping the architect and customer proactively manage uncertainty throughout the engagement.


                  NEW QUESTION # 31
                  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?

                  Answer: B

                  Explanation:
                  If the customer does not need VRF-based segmentation for endpoint traffic, the server/VM VLAN SVIs can be placed in the default VRF rather than creating separate overlay tenant VRFs.


                  NEW QUESTION # 32
                  A customer is upgrading their data center structured cabling to SMF. At the same time the customer wants to upgrade the spine switches in their spine and leaf topology A key goal of this upgrade is to eventually support 400GbE leaf-to-spine links. However, for a while, many of the leaf switches will continue to support 100GbE uplinks. What is a valid recommendation for the spine switches?

                  Answer: C

                  Explanation:
                  The CX 9300-32D is appropriate as a 100/400GbE spine and supports breakout use cases, while
                  4x100G DR QSFP-DD supports SMF and lets the spine connect to current 100GbE leaves during migration to 400GbE.


                  NEW QUESTION # 33
                  A customer has a highly virtualized data center for which you are designing a two-tier L2 data center. What are the characteristics of a design that extends VLANs only to the ToR switches and server ports that strictly need those VLANs? (Choose two.)

                  Answer: C,D

                  Explanation:
                  Limiting VLANs only to required ToR switches and server ports reduces unnecessary Layer 2 flooding/MAC learning and gives network admins tighter control over where each VLAN exists. It is less flexible for server admins than extending all VLANs everywhere.


                  NEW QUESTION # 34
                  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?

                  Answer: B

                  Explanation:
                  Fabric Composer high availability uses a three-node deployment model.
