HPE Network Data Center Professional Architect Sample Questions:

Question 1

A customer is upgrading their data center structured cabling to SMF. At the same time the customer wants to upgrade the spine switches in their spine and leaf topology A key goal of this upgrade is to eventually support 400GbE leaf-to-spine links. However, for a while, many of the leaf switches will continue to support 100GbE uplinks. What is a valid recommendation for the spine switches?

A. CX 10040 switches using 4x100G DR QSFP-DD transceivers
B. CX 10040 switches using 400G QSFP-DD MPO-16 transceivers
C. CX 9300-32D switches using 4x100G DR QSFP-DD transceivers
D. CX 9300-32D switches using 400G QSFP-DD MPO-16 transceivers

Question 2

Which two factors should be part of a data center network's high availability (HA) design?
(Choose two.)

A. Selecting a single top-of-rack switch per rack with no backup
B. Placing all spine switches in a single power zone
C. Redundant power and diverse uplinks between tiers
D. Disabling LACP to simplify configuration
E. VSX (Virtual Switching Extension) between top-of-rack switch pairs

Question 3

You are brought in to a customer with 1,115 employees to update the network and the previous network manager has left the company. What are methods to validate the current network state when the available network documentation is not up-to-date? (Choose two.)

A. Begin searching through file shares for old documentation and compare the files and drawings to each other.
B. Use neighbor discovery protocols to learn neighbor relationships, document the connections and build a topology from the learned information.
C. Interview random company staff to gather the 'tribal knowledge' of how the network functions during normal operations and degraded states.
D. Documenting existing network configuration and topology is not required. Previous iterations of network designs are considered obsolete and the best practice is that new designs are 'clean- sheet' designs.
E. Physically examine the network devices and trace the cables from device to device documenting the connections and cabling type.

Question 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

Question 5

A customer's data center has 40 racks and is growing. The customer asks you to recommend a fabric topology that supports predictable latency and easy horizontal scaling. Which topology should you recommend?

A. Three-tier core-distribution-access
B. Ring topology
C. Full-mesh access layer
D. Spine-leaf (Clos) fabric
