HPE Network Data Center Professional Architect Exam Sample Questions (Q49-Q54):

NEW QUESTION # 49
Drag and Drop Question
Match the switch family with the capability.

Answer:

Explanation:

Explanation:
CX 9300 supports high-density 400G/100G breakout designs, CX 8360 uses Aruba Gen7 ASIC, CX 10000 provides Pensando-powered distributed services, and CX 6405 is a modular chassis platform with redundant management module support.

NEW QUESTION # 50
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. Use neighbor discovery protocols to learn neighbor relationships, document the connections and build a topology from the learned information.
B. Physically examine the network devices and trace the cables from device to device documenting the connections and cabling type.
C. Interview random company staff to gather the 'tribal knowledge' of how the network functions during normal operations and degraded states.
D. Begin searching through file shares for old documentation and compare the files and drawings to each other.
E. 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.

Answer: A,B

Explanation:
When documentation is outdated, the current state should be validated by directly inspecting physical cabling/devices and by using neighbor discovery protocols such as LLDP/CDP to identify real device relationships and build an accurate topology.

NEW QUESTION # 51
What is the best practice for using VSX at the Core of a two-tier design?

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

Answer: D

Explanation:
In a two-tier L2 access design, VSX at the core provides redundant active-active connectivity and default gateway resiliency for access switches. For L3-only or EVPN-VXLAN access designs, routed spine/core behavior is preferred instead.

NEW QUESTION # 52
You are designing a CX data center network for a customer who has indicated that they must integrate the switches in their automation workflows. Which capability enables your customer to fulfill their objectives?

A. NETCONF
B. XML API
C. REST API with JSON
D. gRPC

Answer: C

Explanation:
Aruba CX switches support automation through a REST API using JSON, which enables integration with external automation/orchestration workflows.

NEW QUESTION # 53
A customer's data center is expanding from one row to five rows over the next two years. What design principle should guide the initial fabric design to support this growth?

A. Design only for the current row and redesign the fabric entirely at each expansion
B. Design a modular spine-leaf architecture that allows adding leaf switches and racks incrementally without redesigning the core
C. Avoid discussing future growth with the customer to keep scope narrow
D. Use a flat, non-modular Layer 2 network to keep the initial design simple

Answer: B

Explanation:
A modular spine-leaf design allows incremental scale-out (adding leaves/racks) without re- architecting the fabric, which is essential when the customer has known growth plans. Designing only for the current state, or ignoring growth plans, risks a costly redesign later.
