The core stack is Installed in the MDF and per IOF there is one access stack installed. Based on best practice, what is the most cost-effective update to the switch BOM?
A)
B)
C)
D)
Option B is the most cost-effective solution, as it does not include long-range optics, which are unnecessary given the distances and fiber types specified. The 10GbE-SR optics are suitable for short-range connections up to 300 meters over OM3 fiber and would cover the needs of the longest fiber run mentioned, which is 250 meters. The 10GbE-LRM optics, while capable of reaching up to 220 meters over OM2 fiber, would not be necessary as the longest OM2 run is 71 meters, which is within the range of standard 10GbE-SR optics. Thus, Option B provides the required connectivity without incurring additional costs for long-range optics that are not needed given the fiber infrastructure of HQ2.

During the presentation of your design to the CTO of "Don't Buy at Us" you were informed about the changes they want you to incorporate into the updated design
1. HQ2 will include the EMEA regional distribution center (EMEA-OISTR) next to the HQ2.
2. Only two pairs of 0S1 are available between HQ2 and EMEA-DlSTR.
3. The uplinks from all access stacks need to increase to 2 x 25GbE. the fiber in HQ2 and EMEA-DI5TRI is certified for 25GbE.
4. EMEA-DlSTR needs at least 7 x stack of Aruba 48 ports switches (each stack has 4 members).
Which answer based on best practice is presenting the correct Switch BOM tor the updated design?
A)
B)
C)
D)
Based on the requirements provided by 'Don't Buy at Us,' the updated design needs to accommodate 25GbE uplinks and a minimum of 7 stacks of 48-port Aruba switches for the EMEA-DISTR. Option C is the most suitable based on best practices, as it proposes:
A core configuration consisting of two Aruba 8360-12C in VSX for the collapsed core with ISL of 2x100GbE DAC, which will provide robust core networking with high-speed interconnects, suitable for the demands of a regional distribution center and headquarters.
Aggregation with two stacks, each with 2 Aruba 8360-12C in VSX (ISL 2x100GbE DAC), accommodating the uplink capacity requirements.
Access stacks with a total of 17 stacks of Aruba 6300F 48-port 1GbE Class 4 PoE with 4-port SFP56 (each stack has 4 members, VSF with 50GbE VSF links, 2 x 25GbE uplinks per stack), which exceeds the minimum requirement of 7 stacks and provides the necessary uplink bandwidth.
This configuration supports the 25GbE uplink speeds, satisfies the required number of switch stacks for the EMEA distribution center, and is compatible with the existing 25GbE-certified fiber infrastructure at HQ2 and EMEA-DISTR.
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.
What possible issue with the cote switch selection do you see in regards to the customers' requirements?
In the scenario described, the most significant issue with the core switch selection, according to Aruba Campus Access learning resources, is answer A: 'The core switch will not support the 25GbE downlinks to the distribution switches.' This is a critical consideration because the bandwidth capabilities between the core and distribution layers significantly impact the overall network performance and scalability. If the core switch cannot support 25GbE downlinks, it may create a bottleneck, preventing the distribution switches from operating at their full capacity and affecting the performance of connected devices and applications. Ensuring the core switch has the necessary port speeds and densities to support the intended design and traffic patterns is crucial in network design, as emphasized in Aruba's documentation on campus network architectures.
