                  HPE Network Data Center Professional Architect Exam 認定 HPE7-A12 試験問題 (Q15-Q20):

                  質問 # 15
                  What documents should be included in the solution proposal?

                  正解：C

                  解説：
                  A solution proposal should include the proposed equipment and licensing details in a Bill of Materials. As-built diagrams are post-install deliverables, and architect meeting notes are not normally part of the customer-facing proposal.


                  質問 # 16
                  A customer wants to migrate from a traditional VLAN-based data center network to a VXLAN/EVPN fabric with minimal disruption. What is an appropriate first step in the design process?

                  正解：B

                  解説：
                  Migrations should minimize disruption; a border leaf function bridges legacy VLAN-based segments into the new VXLAN/EVPN fabric so services can be migrated incrementally. EVPN is the standard control plane for VXLAN and should not be skipped, since it provides MAC/IP learning and reduces flood-and-learn behavior.


                  質問 # 17
                  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. One of your junior colleagues has recommended deploying CX 8325-32C BF 6F 2AC Bundle switches for border leaf switches. What issue should you point out with this plan?

                  正解：B

                  解説：
                  The hospital link has strict requirements for high-capacity, encrypted wire-speed connectivity, so the proposed border leaf choice must be validated against that requirement.


                  質問 # 18
                  You are planning a CX-based data center network that applies east-west firewall policies, managed by AMD Pensando Policy and Services Manager (PSM). Which network should be used to communicate with PSM?

                  正解：C

                  解説：
                  PSM is a management/control system for CX 10000 distributed services, so switch-to-PSM communication should use the out-of-band management network, separate from the data underlay and overlay traffic.


                  質問 # 19
                  What is the primary purpose of conducting a "current state assessment" before beginning a data center network design?

                  正解：C

                  解説：
                  A current state assessment creates a factual baseline (topology, traffic flows, capacity, known issues) that the new design must account for or improve upon. It is not a substitute for interviews, nor should it precede requirements gathering in the overall process, nor is it a sales tool.
