HPE Network Data Center Professional Architect Exam Sample Questions (Q41-Q46):

NEW QUESTION # 41
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. Disabling east-west traffic entirely
B. NSX distributed firewall for workload-level policy, integrated with the underlying VXLAN/EVPN fabric for transport
C. Physical firewalls between every server pair
D. VLANs alone, with no additional overlay

Answer: B

Explanation:
NSX's distributed firewall enforces security policy at the vNIC/workload level regardless of physical topology, while the CX VXLAN/EVPN fabric provides the underlying transport. VLANs alone can't achieve workload-level granularity, physical firewalls per server pair are impractical, and disabling east-west traffic breaks application functionality.

NEW QUESTION # 42
During the assumptions and constraints phase of a proposal, the customer mentions they have a hard budget cap that is lower than what is needed for full fabric redundancy. What should the architect do?

A. Silently reduce redundancy without informing the customer
B. Document the budget constraint, present the trade-offs of reduced redundancy options, and let the customer make an informed decision
C. Refuse to continue the engagement
D. Ignore the budget and design for full redundancy anyway

Answer: B

Explanation:
Architects should document constraints transparently and present trade-off options (e.g., single vs. dual spine, partial redundancy) so the customer can make an informed decision, rather than silently compromising the design or refusing to engage.

NEW QUESTION # 43
What is the primary benefit of using EVPN as the control plane for a VXLAN overlay, compared to traditional flood-and-learn VXLAN?

A. EVPN eliminates the need for a physical underlay
B. EVPN removes the need for VTEPs
C. EVPN uses BGP to proactively distribute MAC and IP reachability information, reducing unknown- unicast flooding and improving convergence
D. EVPN only works with IPv6

Answer: C

Explanation:
EVPN leverages MP-BGP to advertise MAC and IP host routes proactively between VTEPs, avoiding the flooding and slow convergence associated with traditional flood-and-learn VXLAN. It still requires an underlay and VTEPs, and works with both IPv4 and IPv6.

NEW QUESTION # 44
You are choosing switches for a new rack, which needs to support several types of traffic including HTTPS multicast streaming, and iSCSI traffic You are attempting to choose between CX 8360v2-32Y6C and CX 8325-48Y8C models both of which can meet the racks' port requirements. Which technical requirement should point you toward the 8325 model?

A. A requirement to allocate two different specific amounts of buffer space to platinum-tier and to gold-tier iSCSI storage
B. A requirement to route the multicast traffic across multiple subnets
C. A requirement to support both IP ECN AND PFC
D. A requirement to support a mix of 10GbE and 25GbE server connections

Answer: A

Explanation:
CX 8325 supports multiple dedicated lossless buffer pools, which fits a design requiring separate buffer allocation for different iSCSI tiers. CX 8360 supports PFC, but with shared loSSLESs resources rather than the same isolated pool model.

NEW QUESTION # 45
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. The customer should place the iSCSI adapters in a PVLAN primary VLAN to ensure trafFIC Is permitted.
C. 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.
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.
