A large multinational financial institution has contracted you to design a new full-stack wired and wireless network for their new 6-story regional office building. The bottom two floors of this facility will be retail space for a large banking branch. The upper floors will be carpeted office space for corporate users, each floor being approximately 100.000 sq ft (9290 sqm). Data centers are all off site and will be out of scope for this project. The customer is underserved by its existing L2-based network infrastructure and would like to take advantage of modern best practices in the new design. The network should be fully resilient and fault-tolerant, with dynamic segmentation at the edge.
The retail space will include public guest Wi-Fi access. Retail associates will have corporate tablets for customer service, and there will be a mix of wired and wireless devices throughout the retail floors. The corporate users will primarily use wireless for connectivity, but several wired clients, printers, and hard VoIP phones will be in use.
The customer is also planning on renovating the corporate office space in order to take advantage of "smart office' technology. These improvements will drive blue-dot wayfinding. presence analytics, and other location-based services
The client decides that they would like for all of their exposed printer, conference room, and VoIP phone
connections to be controlled by a stateful firewall
What could be planned to ensure that these ports will meet the customer's requirements?
To control exposed printer, conference room, and VoIP phone connections with a stateful firewall, utilizing Tunneled Node functionality would be effective. Tunneled Node allows for the encapsulation of wired Ethernet traffic into a user-based tunnel, similar to how wireless traffic is handled. This means that traffic from these devices can be sent through a centralized controller where stateful firewall policies can be applied. This setup ensures that the specific ports used by these devices are subjected to the same level of security scrutiny and policy enforcement as wireless traffic, aligning with the client's requirements for a secure and controlled network environment.

The Advanced License enables enhanced capabilities such as deeper visibility into application flows, advanced routing features, and improved network analytics. Application Recognition allows these switches to identify and classify applications running on the network, enabling more intelligent and dynamic network policies and improving overall network performance and security. The requirement for an Aruba CX Advanced License on these specific models ensures that the necessary software features and support are available to leverage Application Recognition capabilities effectively.
A global cruise line company needs to refresh its current fleet. They will refresh the 'insides' of the ship to be cost-effective and increase their sustainability. They will replace the complete WLAN/LAN hardware of the ship. In this refresh, the company will not refresh its current security requirements. The CIO also wants to limit the number of unused ports in the switches. Future expansion will always mean a refresh of hardware. They start with the smallest ship with a maximum of 800 guests.
Each ship has a LAN infrastructure consisting of two core switches, up to 10 redundant distribution switches, and up to 500 access switches (400 cabins, 100 technical rooms). The core switches are located in the MDF of the ship and the distribution switches are located in the IDFs of the ship. Each cabin and technical room gets one single access switch.
The cabling structure of the ship will not be refreshed. Each IDF is connected to the MDF by SMF, of which two pairs are available for the interconnect between the core and distribution. The length of SM fiber between MDF and IDF is less than 300 meters (980 ft) and the type used is OS1. Each cabin is connected by a single OM2 pair to the IDF, the maximum length is 60 meters (200 ft). Each technical room is connected by a single OM2 pair to the IDF, with lengths between 100 and 150 meters (320 and 500 ft).
For each cabin/technical room the customer is looking to replace their current fan-less 2530/2540 without changing the requirements, except they need to upgrade the uplink to distribution switch to 10 GbE to handle the increased network traffic, and the technical rooms need redundant power.
The WLAN infrastructure will be 1:1 refreshed without new cabling or new AP locations. Their WLAN infrastructure is based on the 200/300 series indoor and outdoor APs running InstantOS (less than 300 APs), the customer has no change in WLAN requirements.
The cruise line company will replace its current Internet connection before the LAN/WLAN refresh. The new Internet connection will provide a 99.8% uptime, which is needed to ensure the paid guest Wi-Fi is always operational. With this new Internet connection, the CIO of the cruise line wants to base the design on the ESP architecture from Aruba because the Internet connection is guaranteed.
Based on best practices, what should you recommend as the correct optic type for the connection between the IDF and the cabins?
Comprehensive and Detailed Explanation From Exact Extract:
Cabling Type in Use:
Each cabin and technical room is connected to the IDF with a single OM2 multimode fiber pair. The maximum length to cabins is 60 meters, and to technical rooms 100--150 meters.
Best Practice for 10 GbE over OM2:
According to Aruba's Campus Access Design Guides and HPE Aruba CX switch transceiver support matrices:
OM2 multimode fiber supports 10GBASE-SR optics up to 82 meters.
Since the maximum run is 60 meters, 10GBASE-SR is fully supported with headroom.
10GBASE-LRM can reach 220 m on MMF, but is not required here because the fiber length is much shorter. SR optics are simpler, lower cost, and recommended in best practices when distances are within OM2 limits.
10GBASE-T RJ-45 (Cat6A) is not applicable, as the cabling is fiber, not copper.
BiDi 40 km optics are for long-haul single-mode fiber links, not short multimode fiber runs.
Aruba Validated Design Reference:
Aruba's Validated Solution Guides for Campus Access state that for short multimode connections (OM2/OM3/OM4), the recommended transceiver type is 10GBASE-SR (SFP+ LC) as it provides the most cost-effective and reliable option within the supported reach.
Requirement Mapping:
Uplinks to access switches in cabins/technical rooms must be 10 GbE capable.
The OM2 cabling length (60--150 m) is within the supported distance for 10GBASE-SR.
Therefore, the correct and most efficient optic choice is 10G SFP+ LC SR 300 m MMF Transceiver.
Final Justification:
Option B is correct because 10GBASE-SR over OM2 supports the required distances, aligns with Aruba design best practices, and avoids unnecessary cost/complexity of LRM or BiDi optics.
Reference Extracts (Aruba Official Study & Design Guides):
Aruba Campus Access Design Guide: recommended transceiver selection for MMF cabling.
Aruba CX Transceiver Guide: 10GBASE-SR supports OM2 up to 82 m, OM3 up to 300 m, OM4 up to 400 m.
A global cruise line company needs to refresh its current fleet. They win refresh the insides' of the ship to be cost-effective and increase their sustain ability. They Mill replace the complete WLAN/LAN hardware of the ship. In this refresh, the company will not refresh Us current security requirements. The CIO also wants to limit the number of unused ports in the switches. Future expansion will always mean a refresh of hardware. They start with the smallest ship with a maximum of 800 guests
Each ship has a LAN infrastructure consisting of two core switches, up to 10 redundant distribution switches, and up to 500 access switches (400 cabins. 100 technical rooms). The Core switches are located in the MDF of the ship and the distribution switches are located in the IDFs of the ship. Each cabin and technical room gets one single access switch.
The cabling structure of the ship will not be refreshed. Each IDF is connected to the MDF by SMF. of which two pairs are available for the interconnect between the core and distribution. The length of SM fiber between MDF and IDF is less than 300 meters (930 ft) and the type used is 0S1. Each cabin is connected by a single 0M2 pair to the IDF. the maximum length is 60 meters (200 ft). Each technical room is connected by a single 0M2 pail to the IDF. with lengths between 100 and 150 meters (320 and 500 ft).
For each cabin/technical room the customer is looking to replace their current fan-less 2530/2540 without changing the requirements, except they need to upgrade the uplink to distribution switch to 10GbEto handle the increased network traffic, and the technical rooms need redundant power.
The WLAN infrastructure will be 1:1 refreshed without new cabling or new AP locations. Their WLAN Infrastructure is based on the 200/300 series Indoor and outdoor APs running instantOS (less than 300 APs). the customer has no change in WLAN requirements.
The cruise line company will replace its current Internet connection before the LAN/WLAN refresh. The new Internet connection will provide a 99.8% uptime, which is needed to ensure the paid guest Wi-Fi is always operational. With this new internet connection, the CIO of the cruise line wants to base the design on the ESP architecture from Aruba because Internet connection is guaranteed.
Based on the best practices, what should you recommend as the most cost-effective switch model for the cabins?
For the cabin switches in the global cruise line's fleet refresh project, the most cost-effective switch model that meets the requirement for fan-less operation, 10GbE uplink capability, and PoE support is the HPE Aruba Networking 6200F 12G Class4 PoE 2G/2SFP+. This switch model offers a compact form factor with sufficient port density for cabin connectivity, Power over Ethernet for powering devices directly through the network cable, and SFP+ ports for high-speed uplink connections to the distribution switches. This choice is in line with the company's aim to upgrade the network infrastructure to handle increased traffic while maintaining a focus on cost-effectiveness and sustainability. The 6200F series is designed for exactly such environments, providing reliable performance and energy efficiency, which is crucial for the limited space and power availability in a ship setting.
