HPE Network Data Center Professional Architect Sample Questions:

1. 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.
Given the scenario, which environmental requirements are provided in this scenario? (Choose two.)

A) traffic micro-segmentation
B) available power to racks
C) airflow direction
D) switch placement
E) encrypted connectivity

2. A customer has deployed CX 10000 switches. Fabric Composer, and Pensando Policy and Services Manager (PSM). The switches are discovered in PSM but no VRFs or networks are added. Now the customer wants to get started by applying micro-segmentation to one network.
The customer tells you that they plan to add a policy with rules for permitting desired traffic from endpoints in this network. They will apply it as an egress policy to the network. At this point they will not add any other networks to PSM or apply policies to them. What warning should you give the customer about this plan?

A) The customer should apply the egress policy at both the VRF and network level to ensure that it works properly.
B) When you apply a policy to one network, it is recommended to add all the networks in its VRF to PSM.
C) The customer must enable strict firewall mode before applying policies to ensure they take effect.
D) An ingress policy not egress policy, is the correct direction for controlling traffic from endpoints.

3. Identify the documentation resources for finding validated information that assists the architect in designing the solution (Choose two.)

A) Configuration guides
B) Competitive documentation
C) Data sheets
D) LinkedIn
E) Product reviews (cnet, networkworld)

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) VLANs alone, with no additional overlay
D) NSX distributed firewall for workload-level policy, integrated with the underlying VXLAN/EVPN fabric for transport

5. An RFP indicates that the proposal must be TAA compliant. What conclusions should you draw?

A) You must propose TAA accessories such as transceivers.
B) You must tell implementers to disable ensure protocols such as Telnet and SNMPv1/v2.
C) You must recommend CX 10000 Series switches.
D) You must recommend switch models that support MACsec on uplinks.
