HPE Network Data Center Professional Architect Exam Sample Questions (Q97-Q102):

NEW QUESTION # 97
A customer's data center uses structured cabling based on MMF O'5. 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 400G QSFP-DD MPO-16 transceivers
B. CX 9300-32D switches using 4x100G DR QSFP-DD transceivers
C. CX 10040 switches using 4x100G DR QSFP-DD transceivers
D. CX 9300-32D switches using 400G QSFP-DD MPO-16 transceivers

Answer: D

Explanation:
With existing MMF OM5 structured cabling, 400G QSFP-DD MPO-16 optics are the valid migration choice for 400GbE spine links. The 4x100G DR option is for single-mode fiber, not MMF.

NEW QUESTION # 98
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 primary VLAN to ensure trafFIC Is permitted.
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 isolated VLAN to ensure traFFIC is forwarded without disruption from VM traffic.
D. CX 10000 switches do not implement east-west firewall policies on traffic in a no-drop PFC queue.

Answer: D

Explanation:
lOSSLess iSCSI traffic uses a no-drop PFC queue, and CX 10000 dsm East-west firewall services are not applied to traffic in that queue. Therefore, no firewall permit rule is required for that traffic.

NEW QUESTION # 99
You have designed a spine and leaf topology, which includes 16 leaf switches and four spine switches. The customer has no existing overlay solution. You are helping the implementer work with the customer to obtain IP address blocks for the design. You plan to ask for these /24 subnets. One for an individual loopback interface for each switch. One for point-to-point connections between leaf and spine switches. What is one of the corrections you must make?

A. Change the /24 subnet request for the individual loopback addresses to a /25 subnet
B. Ask for another subnet for point-to-point links in the overlay VRF
C. Ask for another subnet for loopback IP addresses shared by the two members of each VSX pair
D. Change the /24 subnet request for the point-to-point links to a /23 subnet

Answer: C

Explanation:
In an EVPN-VXLAN spine-leaf design with VSX leaf pairs, you need individual loopbacks for switch identity/control-plane functions and an additional shared loopback per VSX pair for the common VTEP/anycast function.

NEW QUESTION # 100
Which two items are typically part of a "gap analysis" performed after the current state assessment? (Choose two.)

A. Selecting the color of rack labels
B. Booking the customer's travel itinerary
C. Highlighting risks or limitations in the existing infrastructure that the new design must resolve
D. Identifying differences between current capabilities and the customer's stated future requirements
E. Choosing the marketing materials for the proposal

Answer: C,D

Explanation:
A gap analysis compares current-state capabilities against future requirements and highlights existing limitations/risks that the new design needs to address. Travel, marketing, and label colors are unrelated to gap analysis.

NEW QUESTION # 101
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. Use a flat, non-modular Layer 2 network to keep the initial design simple
B. Design only for the current row and redesign the fabric entirely at each expansion
C. Design a modular spine-leaf architecture that allows adding leaf switches and racks incrementally without redesigning the core
D. Avoid discussing future growth with the customer to keep scope narrow

Answer: C

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.
