HPE Network Data Center Professional Architect Exam Sample Questions (Q68-Q73):

NEW QUESTION # 68
You are delivering a spine and leaf architecture based on 18 CX 8360-48Y6C v2 leaf switches and two CX 8325-32C spine switches. The leaf switches support servers with 10 and 25 GbE ports. Currently you are planning to use two 100 Gbps uplinks per leaf switch. The customer returns with the requirement to increase the uplink bandwidth by at least 50% per leaf switch.
What is a valid change to the plan?

A. Add another 100 GbE link between each leaf switch and both spine switches
B. Add another 100 GbE link to each leaf switch. One switch in each VSX pair connects to spine 1, and one switch connects to spine 2.
C. Add a third CX 8325-32C switch and connect it to each leaf switch with a 100 GbE link
D. Convert both uplinks on each leaf switch (and connected spine switches) to 200 GbE links

Answer: C

Explanation:
Each leaf currently has 2 × 100GbE uplinks = 200Gbps. Adding a third spine with one 100GbE link from each leaf increases each leaf to 300Gbps, meeting the 50% increase requirement. The CX 8325-32C has enough ports to connect to all 18 leaves.

NEW QUESTION # 69
Which of the following is an appropriate deliverable to include in a High-Level Design (HLD) document, as opposed to a Low-Level Design (LLD)?

A. Specific IP addressing for every VLAN
B. Switch configuration CLI commands
C. Exact port-by-port cabling diagram
D. Conceptual topology diagram and overall architecture rationale

Answer: D

Explanation:
An HLD captures the conceptual architecture, topology, and design rationale at a strategic level.
Detailed cabling diagrams, IP addressing schemes, and CLI configurations belong in the LLD, which documents implementation-level detail.

NEW QUESTION # 70
Waratah Hospital, based in Australia, is planning to move many data center services to new facility. (The remaining legacy data center will not be part of this project.) Waratah Hospital hired an external consultant to assist with the new data center network design.
Based on the requirements for the data center network infrastructure, the external consultant has created a high-level design. The below summarizes the content of the design document.
Requirements and information:
- Six racks in the data center room (single row).
- Redundant Top of Rack leaf switches with back-to-front cooling in each rack, providing 10/25 Gbps connectivity to servers, storage, and other devices.
- Four 100 GbE uplinks per leaf switch.
- The customer requested to install all switch ports facing the back of the rack racks (hot aisle.)
- OOB management for servers, storage, and network has to be provided through an external switch with back-to-front cooling. This switch has to be included in the solution. One OOB switch provides connectivity for two racks.
- Core equipment for the OOBM network is being reused.
- Middle-of-row spine switches.
-The data center should connect to the hospital building with links that provide 400 Gbps.
- Internet access is provided through an existing firewall cluster with two firewalls, each firewall in one data room. The second firewall is operating in standby mode, VRRP is utilized on the firewalls for failover. The data center network should connect to these firewalls with links that total
100 Gbps.
- The external link is a dark fiber direct link based on single-mode fiber (OS2). The distance to the main hospital 1.5 KM. The links will terminate on two core switches in the hospital.
The customer also requires:
- 99.999% uptime for this life-critical environment.
- Planned and unplanned downtime has to be minimized.
- Software upgrades are only allowed once per year with close to zero downtime.
- All life-critical resources are accessed locally, and all resources exist within the hospital campus.
- Waratah Hospital requires a highly secure environment for the data center. Encrypted wire speed connectivity between the data room and the hospital is a must-have because the link between the buildings crosses a public road.
- Waratah Hospital has a mix of virtualized (vSphere) servers. Nutanix storage, bare metal servers, backup servers and other devices.
In the past, the hospital has had a security breach that resulted in data loss, network downtime, and identity theft.
Refer to the scenario. You have learned that the customer needs to extend two VRFs between the new data center facility and the hospital. To meet with the requirements of the scenario and general best practices, what should you recommend for connecting border leaf switches to the hospital core?

A. 4x 100 Gbps links, establishing a full mesh between two border leaf switches and two hospital core switches. Each link should have two subinterfaces acting as routed only ports.
B. 8x 50Gbps links that are all routed only ports (ROPs). These ports establish two full meshes between two border leaf switches and two hospital core switches.
C. 4x 100 Gbps links that are routed only ports. Border leaf switch 1 has two ports that connect to hospital core switch 1. Border leaf switch 2 has two ports that connect to hospital core switch 2.
D. 8x 50Gbps links that establish two full meshes between two border leaf switches and two hospital core switches. The 4 links that connect to the hospital core 1 in one VSX LAG, and the other 4 links are in another VSX LAG.

Answer: A

Explanation:
This provides 400Gbps total, full-mesh resiliency, and separate routed connectivity for the two VRFs.

NEW QUESTION # 71
Which two are valid reasons to recommend a routed underlay (Layer 3 to the leaf) in a VXLAN/EVPN fabric design? (Choose two.)

A. It guarantees zero oversubscription regardless of hardware
B. It removes dependency on spanning tree in the underlay
C. It requires no IP addressing on the underlay
D. It provides deterministic, ECMP-based load balancing across all spine-leaf links
E. It eliminates the need for any overlay technology

Answer: B,D

Explanation:
A routed underlay removes STP dependency and enables ECMP across all spine-leaf paths for deterministic load balancing and fast convergence. It still requires underlay IP addressing, doesn't guarantee zero oversubscription (that's a hardware/design choice), and doesn't eliminate the need for an overlay if one is desired for mobility/segmentation.

NEW QUESTION # 72
A customer currently has a data center network that uses CX switches and Pensando to implement east-west firewalling. The data center is currently highly virtualized with VMware.
However, the customer is considering migrating some workloads to HPE VMs running on HPE Morpheus VM Essentials (VME). What should you explain?

A. The customer will not be able to implement the east-west firewall policies for traffic originating from the HPE VMs, but can continue to use the1nnatingcies to secure other data center traffic.
B. The customer will not be able to implement microsegmentation between the HPE VMs on the same subnet, but can implement segmentation between VMs on different subnets.
C. The customer should purchase the HPE Morpheus Enterprise license to enable support for PVLAN and the full firewall features, including microsegmentation.
D. The customer should use the VME DSS plug-in to utilize the full firewall features, including microsegmentation.

Answer: D

Explanation:
HPE Morpheus VM Essentials includes the HPE Aruba Networking CX DSS plug-in for CX 10000 integration, enabling both macro-segmentation and microsegmentation for VME workloads.
