HPE Network Data Center Professional Architect Exam 認定 HPE7-A12 試験問題 (Q53-Q58):

質問 # 53
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.
In this scenario, the customers servers are HPE Servers. For the iLO ports, you propose a 6300M switch for each rack. What is the best practice to connect these switches to the data center data plane?

正解：A

解説：
iLO/OOB management should remain on the out-of-band management network, separate from the production data plane.


質問 # 54
A customer running VMware with NSX asks whether they still need to design VLANs on the physical CX switches. What is the correct guidance?

正解：B

解説：
Even with NSX handling overlay segmentation for workloads, the physical underlay still requires basic VLANs/subnets for functions like VTEP/transport connectivity and out-of-band management; NSX segments do not need to map one-to-one with physical VLANs, and a pure L2 underlay is not required (a routed underlay is typically preferred).


質問 # 55
What is a key advantage of an active-active dual-homed server NIC design using VSX/MC-LAG at the access layer compared to active-standby NIC teaming?

正解：A

解説：
Active-active dual-homing (via VSX/MC-LAG) allows both server uplinks to forward traffic simultaneously, increasing available bandwidth and providing sub-second failover compared to active-standby teaming, where one link sits idle.


質問 # 56
Refer to the exhibit.

You are designing a data center network. This customer requests that you connect the data center core their firewalls. The customer uses six VRFs for segmentation, and the firewalls are responsible for handling traffic in all of the VRFs.
What is the recommended design for the links between the data center core switches and the firewalls?

正解：B

解説：
From the exhibit:
1. Links 1 and 3 connect the two VSX core switches to the active firewall.
2. Links 2 and 4 connect the two VSX core switches to the passive firewall.
Therefore, each firewall receives its own VSX multi-chassis LAG.


質問 # 57
Which two questions should be asked to properly size the data center fabric's east-west bandwidth requirements? (Choose two.)

正解：B、E

解説：
Understanding the east-west to north-south traffic ratio and the intended server-to-leaf oversubscription ratio are both essential inputs for sizing spine and leaf uplink bandwidth correctly. The remaining options are irrelevant to fabric sizing.
