HPE Network Data Center Professional Architect Exam Sample Questions (Q83-Q88):

NEW QUESTION # 83
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?

Answer: D

Explanation:
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.


NEW QUESTION # 84
What is the correct statement with regard to flow synchronization on the HPE Aruba Networking CX 10000 Distributed Services Modules (DSM) operating in VSX?

Answer: A

Explanation:
In a CX 10000 VSX pair, firewall flows are synchronized across the logical VSX VTEPs, and DSM flow sync is done between matching DSMs, not randomly or cross-mapped between DSM1 and DSM2.


NEW QUESTION # 85

What should you explain?

Answer: D

Explanation:
Fabric Composer provides VMware vSphere integration and automation for data center fabric operations, including simplifying/automating VLAN and network provisioning.

Answer: B

Explanation:
For two VRFs and an active/standby firewall pair, each firewall should have redundant VSX LAG connectivity with separate VLAN/SVI transit per VRF.


NEW QUESTION # 87
During the assumptions and constraints phase of a proposal, the customer mentions they have a hard budget cap that is lower than what is needed for full fabric redundancy. What should the architect do?

Answer: B

Explanation:
Architects should document constraints transparently and present trade-off options (e.g., single vs. dual spine, partial redundancy) so the customer can make an informed decision, rather than silently compromising the design or refusing to engage.
