HPE Network Data Center Professional Architect Sample Questions:

Question #1
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?

A. VXLAN is not supported on Aruba CX switches
B. Fabric Composer requires the customer to eliminate all VLANs
C. Existing automation scripts written for NX-OS APIs will need to be rewritten or replaced for the new platform
D. The customer's existing Nexus switches will remain as the primary management plane

Question #2
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. Precisely how many ports use 10 GbE versus 25 GbE and whether that mix might change.
C. Whether the customer requires the flexibility to extend VM networks across a routed underlay.
D. How the rack and switches installed in it are oriented toward hot and cold aisles.

Question #3
You are designing an L3 spine and leaf architecture for a customer based on CX 10000 Series switches as leaf switches. The customer has added a requirEMENT that the leaf switches also support servers' iSCSI adapters. You have verified your design also meETS The customer's needs for lossless iSCSI. The customer asks for advice on ensuring that THE East-west firewall permits the iSCSI traffic. What should you explain?

A. The custOMER should place the iSCSI adapters in a PVLAN isolated VLAN to ensure traFFIC is forwarded without disruption from VM traffic.
B. Fabric Composer supports VM tag-based Endpoint Groups (EPGs) which will make it easy for the customer to select the iSCSI traffic and permit it.
C. The customer should place the iSCSI adapters in a PVLAN primary VLAN to ensure trafFIC Is permitted.
D. CX 10000 switches do not implement east-west firewall policies on traffic in a no-drop PFC queue.

Question #4
You are presenting the proposed solution to the customer. The customer required micro- segmentation to be implemented so you designed the network to use the Aruba CX 10000 DSS.
The customer has questions about the implementation of PVLAN. What is a true statement about PVLAN that will help the customer understand the fundamentals of micro-segmentation?

A. The Community VLAN in a PVLAN configuration is generally not recommended for endpoints because they can communicate freely with all endpoints on the secondary VLANs.
B. The Primary VLAN in a PVLAN configuration is generally not recommended for endpoints because they can communicate freely with all endpoints on the secondary VLANs.
C. The Primary VLAN in a PVLAN configuration does not support having endpoints connected because the local proxy ARP configuration on the SVI excludes the Primary VLAN and only functions for the secondary VLANs/
D. The Isolated VLAN in a PVLAN configuration is generally not recommended for endpoints because they can communicate freely with all endpoints on the secondary VLANs.

Question #5
Which statement is true about VSX design?

A. VSX peer keepalive links only supports 40G and 100G ports.
B. VSX Inter-Switch Link can implemented over indirect links.
C. VSX Inter-Switch Link must be implemented using direct links between peers.
D. VSX peer keepalive can be implemented over a VSX LAG.
