                  HPE Network Data Center Professional Architect Exam Sample Questions (Q17-Q22):

                  NEW QUESTION # 17
                  You delivered an L3 spine and leaf topology to a customer several years ago. The solution consisted of two CX 8325-32C switches at the spine and 20 CX 8325-48Y8C leaf switches. The leaf switches operate as 10 VSX pairs. The customer would now like to double the forwarding capacity of the topology. What should you recommend?

                  Answer: B

                  Explanation:
                  The current design has 2 spine switches, with each leaf connecting to each spine. Adding 2 more spines doubles the number of ECMP spine paths and therefore doubles the leaf-to-spine forwarding capacity, while staying within CX 8325-32C port limits.


                  NEW QUESTION # 18
                  When proposing Aruba CX switches with Fabric Composer for a customer replacing a legacy Cisco Nexus environment, what is an important assumption to document regarding the migration?

                  Answer: D

                  Explanation:
                  Since NX-OS and AOS-CX have different APIs and CLI syntax, any existing automation tooling built against Nexus will not be directly portable and should be flagged as a migration assumption/risk. AOS-CX does support VXLAN, and Fabric Composer does not eliminate VLANs.


                  NEW QUESTION # 19
                  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 are trying to decide between the CX 9300 and CX 8325 switches for the border leaf switches. What is a hard requirement for this customer that affects this decision?

                  Answer: D

                  Explanation:
                  The scenario states that encrypted wire-speed connectivity is a must-have because the link crosses a public road.


                  NEW QUESTION # 20
                  A customer wants to convert as many upfront costs into smaller ongoing bills as possible. For which components can HPE GreenLake for Networking provide recurring billing?

                  Answer: B

                  Explanation:
                  HPE GreenLake for Networking provides an as-a-service consumption model that can convert networking hardware, software subscriptions, and support into recurring billing.


                  NEW QUESTION # 21
                  What is an advantage of using a VSX-pair instead of two discrete switches to connect servers, storage, firewalls, and other workloads?

                  Answer: B

                  Explanation:
                  A VSX pair allows downstream devices such as servers, storage, and firewalls to connect with active-active LAGs across two physical switches, improving redundancy without requiring the endpoint to run a complex HA protocol.
