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.
Refer to the rack requirements in the scenario. Which additional information can help you choose between CX 8325-48Y8C and CX 8360-48Y6C models?

A) Whether the customer has a preference for AOC versus DAC cables.
B) How the rack and switches installed in it are oriented toward hot and cold aisles.
C) Whether the customer requires the flexibility to extend VM networks across a routed underlay.
D) Precisely how many ports use 10 GbE versus 25 GbE and whether that mix might change.

2. Which information should you attempt to discover during your first data center network design meetings with the customer? (Choose two.)

A) What are the bandwidth requirements for the spine switches?
B) What are the data center's addresses?
C) What's the budget allocated to this project?
D) Is it a greenfield or brownfield deployment?
E) What are the team's training needs for the project?

3. You are modernizing a customer's legacy three-tier architecture with an L3 spine and leaf topology. The CX switches in the topology will provide the overlay. The customer data center uses six VRFs. The customer has asked for service leaf switches to connect to two clustered firewalls, which route and filter traffic between the VRFs. How can you maximize the efficiency of the traffic flow between subnets in the same VRF?

A) Within each VRF, use the distributed gateway (L3 anycast) model for most subnets but the centralized gateway design for the subnets with the highest security needs
B) Use the firewall duster as centralized gateways for these subnets
C) Use the centralized gateway model for these subnets, selecting a different centralized gateway for each VRF
D) Use the distributed gateway (L3 anycast) model for these subnets

4. What is the best practice for using VSX at the Core of a two-tier design?

A) You should implement VSX at the core when the access is layer 3 only with OSPF routed traffic forwarding between core and access.
B) You should implement VSX at the core when the access switches implement EVPN VXLAN.
C) You should never implement VSX at the core of a two-tier design.
D) You should implement VSX at the core when the access layer operates at layer 2 only.

5. You have successfully installed, configured, and migrated the customer to the new Aruba CX data center equipment. What documents are normally part of the post-installation deliverables?

A) Support entitlement QR codes
B) Completed RFP Responses
C) Inventory
D) Equipment data sheets
