Requirement: Nurse workstation tracking = asset tracking. Aruba’s solution for tracking movable medical equipment or workstations relies on the Aruba Meridian and Tags platform.

Correct Options:

C. Aruba Tags Configuration App

Used to configure and assign Aruba Tags (BLE-based asset tracking beacons) to specific assets such as nurse workstations.

Essential for onboarding and managing tagged assets in the Aruba Meridian environment.

D. Asset Tracking Subscription

Required to enable asset tracking services in Aruba Central/Meridian.

Provides the software capability to track and monitor tagged devices in real time.

F. Map Subscription

Required to provide floorplan visualization of tracked assets.

Nurse workstations can then be displayed on hospital floor maps in the Meridian app.

Why the other options are incorrect:

A. Aruba User Experience Insight (UXI): Provides monitoring of the end-user experience (synthetic tests for apps, Wi-Fi, SaaS), not asset tracking.

B. AirWave: Legacy on-premises monitoring platform for wired/wireless devices. Does not support asset tracking of nurse workstations.

E. Client Insight: Provides profiling and visibility into connected clients (e.g., IoT, laptops, phones), not physical asset tracking.

Aruba Design Guide Reference:

Aruba Location Services Solution Guide: Asset tracking requires three components → Tags, Asset Tracking Subscription, and Map Subscription.

Tags App is needed for configuration and assignment of tags to assets.

Final Justification:

To track nurse workstations as assets, the solution must include:

Aruba Tags Configuration App (C) to onboard/configure tags.

Asset Tracking Subscription (D) to enable asset-tracking features.

Map Subscription (F) to visualize tracked workstations on hospital floorplans.

A 2-tier campus LAN architecture, consisting of the core and access layers, is typically suitable for smaller campuses or networks with limited numbers of wiring closets. This simplified architecture eliminates the need for a dedicated aggregation layer, which is more common in larger, more complex network environments (the 3-tier architecture). In a small campus setting with only a few wiring closets, a 2-tier design can provide sufficient performance and scalability, reducing complexity and potentially lowering costs. This architecture allows for direct connectivity between the access layer, where end devices connect to the network, and the core layer, which routes traffic to and from the campus network. The use of a 2-tier architecture in such scenarios is driven by the network's size and the simplicity of its requirements, making it an efficient and effective choice.

In the context of the ESP architecture from Aruba and the specific requirements of the cruise line company, the best practice would be to place management VLANs in the underlay and user VLANs in the overlay. This design allows for a clear separation of management traffic from user data, enhancing security and network performance. The management underlay ensures secure and reliable access to network infrastructure for administrative purposes, while the user overlay allows for flexible and dynamic segmentation of user traffic. This approach is aligned with best practices for network design, where critical management traffic is isolated from user data to prevent unauthorized access and potential security breaches. It also supports the cruise line's need for a robust and secure network to ensure the operational reliability of paid guest Wi-Fi and other critical services.

One of the key advantages of using a Virtual Switching Extension (VSX) pair instead of two discrete switches for connecting servers, storage, firewalls, and other workloads is that both members in a VSX pair can be upgraded without any downtime for the workload (Option C). VSX technology provides advanced high availability features that allow for non-disruptive software upgrades, meaning that one switch in the VSX pair can be upgraded while the other continues to handle network traffic, thereby maintaining continuous operation of the connected workloads. This seamless failover capability ensures that there is no interruption to the critical services running on the network, making VSX an ideal solution for environments where uptime is paramount.

When upgrading existing Multimode Fiber (MMF) infrastructure to accommodate equipment capable of 10 GbE speeds, two primary considerations are the length of the MMF fiber (Option A) and the type of MMF fiber (Option C). The length of the fiber impacts the signal quality and bandwidth capacity, with longer lengths potentially requiring signal conditioning or different types of fiber to support higher speeds. The type of MMF fiber, such as OM1, OM2, OM3, or OM4, significantly affects its bandwidth capabilities and distance limitations at 10 GbE speeds. OM3 and OM4 fibers are designed to support 10 GbE transmissions over longer distances compared to OM1 and OM2, making them more suitable for upgrades to higher speeds. Understanding these factors is crucial to ensure the existing fiber infrastructure can support the desired network performance without extensive modifications or replacements.

The primary differences between OM4 and OM5 cabling include their support for transmission distances and the type of multimode fiber. OM4 fiber supports distances up to 100 meters when using 100 Gbps transceivers (Option A), which is suitable for most data center and enterprise networking applications. OM5, also known as Wide Band Multimode Fiber (WBMMF) (Option C), extends this capability by supporting higher wavelengths in the 850 to 950 nm range, allowing for more efficient multiplexing and potentially longer distances or higher bandwidths under certain conditions. This makes OM5 a more versatile and future-proof option for organizations looking to deploy advanced technologies like shortwave division multiplexing.

Comprehensive and Detailed Explanation From Exact Extract:

Customer Requirement Recap (cruise line scenario):

Each ship has two core switches in the MDF.

Each core connects to up to 10 distribution switches in IDFs.

Uplinks between core and distribution are 25 GbE SMF links.

Cabins/technical rooms connect to distribution switches via 10 GbE uplinks.

Only 8 uplinks per core switch are required to meet the design.

Issue Identified:

The selected core switch platform provides dozens of 25/40/100 GbE ports, far exceeding what is needed for this environment.

With only 8 ports in use per core, that leaves ~40 unused ports.

This creates a cost inefficiency — the customer is paying for hardware capacity that will remain idle.

Why the Correct Answer is B:

The main “issue” is not about lack of capability (uplinks and VSX are supported).

The issue is about overprovisioning — the core switch selection results in a large number of unused ports, which is against the CIO’s requirement to limit unused capacity and avoid waste.

Why Not the Other Options:

A. Core will not support 25 GbE downlinks → Incorrect. The selected core switches do support 25 GbE uplinks.

C. Not enough ports for VSX links → Incorrect. Core switches only require a few ports for VSX interconnect, which is easily supported.

D. Core will not support 10 GbE downlinks to cabins → Incorrect. Core switches don’t connect directly to cabins; those connections terminate at the distribution layer.

Aruba Design Guide Reference:

Aruba ESP Campus Design Principles: Switch sizing should consider right-sizing the port count to avoid excessive unused capacity.

Aruba Validated Solution Guides: Core switches should be selected for performance, scalability, and efficiency — not overspec’d beyond realistic need.

Final Justification:

The issue with the customer’s core switch selection is not about functionality, but about efficiency. Only 8 uplinks per core are needed, leaving ~40 ports unused — which contradicts the CIO’s goal of minimizing unused ports.

Based on the campus design provided and considering an EVPN VXLAN Fabric, the most appropriate layer to be designed as a Border Persona would be the "Services Aggregation" layer. In an EVPN VXLAN architecture, the Border or Border Leaf nodes provide connectivity to external networks, such as WAN, internet, or private connections. They are responsible for routing traffic into and out of the VXLAN fabric and typically also handle services like firewalling, load balancing, and other network services.
