HPE Network Data Center Professional Architect Exam Sample Questions (Q31-Q36):

NEW QUESTION # 31
What are important characteristics to mention while discussing possible connections for VMware hosts to server-access-switches?

A. Only bare metal servers running WindowsServer or Oracle Solaris can use LACP.
B. VMware ESXi requires the appropriate license to support LACP.
C. Source MAC Load balancing is always the best option.
D. LACP is an old protocol and should no longer be used.

Answer: B

Explanation:
VMware hosts can use LACP only when the required vSphere features/licensing are available, typically with a vSphere Distributed Switch. This is important when designing host-to-access- switch connectivity.

NEW QUESTION # 32
You are proposing an L3 spine and leaf topology to a customer. The solution consists of four CX
8325-32C switches at the spine and two CX 8325-48Y8C switches in each server rack. For this customer, you are using the leaf switches in a rack to provide the border leaf functionality. The customer's data center is growing and the customer asks you how many total server racks this solution can scale to support. What should you say?

A. 0
B. 1
C. 2
D. 3

Answer: A

Explanation:
Each CX 8325-32C spine has 32 usable 100G ports. Each server rack has two leaf switches, and each spine needs one connection to each leaf, so each rack consumes 2 ports per spine. 32 ÷ 2
= 16 total racks.

NEW QUESTION # 33
Your long-time customer has just acquired a company and they are planning on bringing the new data center sites up to their standards. They have asked for a bill of materials given only locations and port counts at the data center sites. What are valid assumptions that should be documented in the proposal? (Choose two.)

A. The project will be funded by the capital budget of the acquired company.
B. The acquired company's data center cooling plant allows for the back-to-front airflow preferred by your customer.
C. The acquired company's full-time staff will be converted to contractors.
D. The acquired company's data center racks are sufficient for the new equipment and will be reused.
E. The acquired company's IP schema in the existing data centers will be converted to IPv6.

Answer: B,D

Explanation:
With only locations and port counts, the proposal should document physical-site assumptions that affect deployment feasibility, such as adequate cooling/airflow and usable rack capacity for the new equipment.

NEW QUESTION # 34
A customer has a highly virtualized data center for which you are designing a two-tier L2 data center. What are the characteristics of a design that extends VLANs only to the ToR switches and server ports that strictly need those VLANs? (Choose two.)

A. more control for network admins
B. smaller MAC address tables at the access switches
C. smaller ARP tables on the core switches
D. more flexibility for server admins
E. smaller routing table on core switches

Answer: A,B

Explanation:
Limiting VLANs only to required ToR switches and server ports reduces unnecessary Layer 2 flooding/MAC learning and gives network admins tighter control over where each VLAN exists. It is less flexible for server admins than extending all VLANs everywhere.

NEW QUESTION # 35
Refer to the rack requirements in the scenario. What additional information would help you select between the CX 8325-48Y8C and CX 8360-48Y6C models?

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

Answer: C

Explanation:
While both the Aruba CX 8325-48Y8C and the CX 8360-48Y6C provide high-density SFP28/QSFP28 options, their underlying ASIC architectures impose fundamentally different interface speed-negotiation constraints.
The CX 8325 utilizes switch silicon that organizes its 48 SFP28 downlink ports into discrete physical interface groups (quad-port groupings). Within each interface group on the CX 8325, all four contiguous ports must operate at the exact same physical speed (i.e., all ports in the group must be configured for either 10GbE or 25GbE operation). Mixing 10G and 25G transceivers within the same port group is unsupported.
In contrast, the Aruba CX 8360 family (powered by Aruba's Gen7 ASIC architecture) allows completely independent, per-port auto-speed detection and multi-rate configuration on its SFP28 interfaces without interface group restrictions. Thus, determining the exact server connection distribution across 10GbE and
25GbE transceivers, as well as the volatility of future speed upgrades, dictates whether the CX 8325 group constraints will impede operations or whether the CX 8360's granular port independence is necessary.
