                                HPE Network Data Center Professional Architect Sample Questions:

                                1. A customer's data center is expanding from one row to five rows over the next two years. What design principle should guide the initial fabric design to support this growth?

                                A) Design only for the current row and redesign the fabric entirely at each expansion
                                B) Use a flat, non-modular Layer 2 network to keep the initial design simple
                                C) Avoid discussing future growth with the customer to keep scope narrow
                                D) Design a modular spine-leaf architecture that allows adding leaf switches and racks incrementally without redesigning the core


                                2. You are delivering a spine and leaf architecture based on 18 CX 8360-48Y6C v2 leaf switches and two CX 8325-32C spine switches. The leaf switches support servers with 10 and 25 GbE ports. Currently you are planning to use two 100 Gbps uplinks per leaf switch. The customer returns with the requirement to increase the uplink bandwidth by at least 50% per leaf switch.
                                What is a valid change to the plan?

                                A) Convert both uplinks on each leaf switch (and connected spine switches) to 200 GbE links
                                B) Add a third CX 8325-32C switch and connect it to each leaf switch with a 100 GbE link
                                C) Add another 100 GbE link to each leaf switch. One switch in each VSX pair connects to spine 1, and one switch connects to spine 2.
                                D) Add another 100 GbE link between each leaf switch and both spine switches


                                3. Which factor should most influence the decision to use a two-tier (spine-leaf) versus a three-tier (spine-super spine-leaf) fabric design?

                                A) The number of employees in the customer's HR department
                                B) The color of the network diagrams
                                C) The total scale of the fabric -- very large environments exceeding the port capacity of a two-tier spine may require a super-spine tier to interconnect multiple spine-leaf pods
                                D) The customer's preferred switch vendor logo


                                4. A customer's security team requires micro-segmentation down to the individual workload level within the data center. Which technology combination best satisfies this requirement in an Aruba CX + VMware environment?

                                A) Physical firewalls between every server pair
                                B) Disabling east-west traffic entirely
                                C) NSX distributed firewall for workload-level policy, integrated with the underlying VXLAN/EVPN fabric for transport
                                D) VLANs alone, with no additional overlay


                                5. What is a key reason to interview the customer's storage team during data center network design, even if the network team owns the project?

                                A) Storage teams have no relevant network requirements
                                B) Storage protocols like FC, FCoE, iSCSI, or NVMe-oF may impose specific fabric requirements (e.g., lossless Ethernet, dedicated VLANs, zoning)
                                C) Storage teams only care about server hardware, not networking
                                D) It is unnecessary since storage traffic never traverses the data center network
