質問 # 36
A customer is upgrading its data-center structured cabling to SMF. At the same time, the customer wants to upgrade the spine switches in its spine-and-leaf topology. A key objective of this upgrade is to eventually support 400GbE leaf-to-spine links. However, for some time, many leaf switches will continue to support
100GbE uplinks.
What is a valid recommendation for the spine switches?
正解：D
解説：
Modern data center physical layer design requires balancing long-term bandwidth migration with backward compatibility for existing access tiers. In this scenario, the customer has upgraded the cabling plant to Single- Mode Fiber (OS2) and requires spine switches capable of native 400GbE forwarding, while currently accommodating legacy 100GbE leaf uplinks.
The HPE Aruba CX 9300-32D switch is the premier fixed 1U data center spine platform, delivering 32 ports of high-density 400GbE QSFP-DD (Double Density). To interface with existing 100GbE leaf switches over single-mode fiber, the architect must specify 400G 4x100G DR (Datacenter Reach) QSFP-DD transceivers.
The 400G DR4/eDR4 optical architecture utilizes four parallel single-mode fiber pairs (transmitting over an MPO-12/APC single-mode trunk) where each optical lane operates at 100Gbps using PAM4 modulation. By utilizing an optical breakout cable, each 400G QSFP-DD port splits cleanly into four discrete 100G DR (or
100G FR/LR via interoperable optical gear) links connecting to standard 100GbE QSFP28 leaf uplinks. MPO-
16 SR8 transceivers are engineered strictly for Multi-Mode Fiber (MMF) short-reach optics and are physically incompatible with SMF plants.

質問 # 37
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?
正解：C
解説：
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.

質問 # 38
Order the severity levels (highest impact on top) into the righthand box.
Drag & Drop
正解：
解説：
Explanation:
* directly impact health and safety
* sustain core business operations
* support productivity
* low priority services
During requirements analysis and risk assessment, enterprise architects prioritize business functions and network failures according to standardized impact severity hierarchies. Aligning network redundancy, High Availability (HA) mechanisms, and Mean Time to Recovery (MTTR) service level agreements requires classifying workloads by consequence of disruption.
* Directly impact health and safety: The highest architectural priority in any engineering standard is human life and personal physical safety. In healthcare environments (such as hospitals), industrial facilities, and emergency dispatch centers, network outages that disrupt life-support monitoring, surgical theater feeds, or hazardous telemetry represent catastrophic Severity 1 events.
* Sustain core business operations: The secondary tier governs mission-critical services required for transactional operations, revenue generation, and regulatory compliance (e.g., electronic health records, financial payment gateways, primary databases).
* Support productivity: The tertiary tier encompasses internal operational tools that facilitate workforce collaboration and administrative workflow (e.g., corporate email, document shares, intranet portals).
* Low priority services: The lowest tier represents non-essential auxiliary workloads (e.g., guest Wi-Fi, non-production staging environments, testing lab clusters), where downtime causes negligible commercial impact.

質問 # 39
To prepare for a data center network implementation, you have asked a customer for a list of VLANs to support. The customers list for several VMware ESXi hosts includes 4095. What follow up question should you ask?
正解：A
解説：
In VMware ESXi, VLAN ID 4095 on a port group means VLAN trunking/VGT, allowing guest VMs to tag traffic themselves. You need to identify the actual VLAN tags used by those VMs.
質問 # 40
The customer runs a 24/7 production facility and is concerned that the migration could interrupt the production line.
Which two approaches can minimize or eliminate this disruption? Choose two.
正解：B、D
解説：
Migrating continuous, 24/7 mission-critical production environments requires migration methodologies designed to prevent widespread downtime and maintain rollback capabilities.
The primary best-practice approach is parallel infrastructure deployment. By installing, cabling, and configuring the new Aruba CX core and leaf infrastructure alongside the legacy network, architects can establish temporary inter-switch links (trunks) to extend Layer 2 VLANs between the environments. This architecture allows routing protocols, overlay services, and management platforms to be validated prior to migrating live production traffic, enabling a controlled cutover.
Concurrently, at the server access edge, executing a staged migration that replaces one access switch at a time using a predefined, documented patch plan limits disruption to a small, isolated set of endpoints. Dual-homed servers and clustered systems maintain network connectivity across redundant links while individual connections are migrated. Conversely, shutting down the facility for a single cutover ( " big-bang " ) violates the customer ' s 24/7 uptime mandate, while migrating access layers before establishing core/distribution infrastructure introduces severe forwarding and spanning-tree loop risks.
