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.
The week after the presentation of your design to the CIO of the cruise line company, the CIO calls you to discuss increasing the security of the wired network Infrastructure. Since one of their competitors had one of their cruise ships cyber hacked, the CSO of the cruise line has mandated increased security on the wired network. They have heard about dynamic segmentation and central and decentral overlay networks.
What would you advise as the most cost-efficient solution?
Given the need to increase the security of the wired network infrastructure while being cost-efficient, advising the cruise line company to standardize on Aruba 6300 switches for the access layer is the most appropriate solution. The Aruba 6300 Series offers advanced features suitable for such environments, including high-performance, scalability, and enhanced security capabilities. Adding a cluster of 9240 Gateways for implementing central overlay networks on a User-Based Tunneling (UBT) basis further strengthens the network's security posture. This setup supports dynamic segmentation, which allows for the enforcement of consistent policies and secure access across the network, irrespective of the user or device type. This architecture not only meets the increased security requirements set forth by the cruise line's CSO but also aligns with the company's existing infrastructure and future refresh plans, ensuring cost-efficiency and sustainability.
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 would take to ensure redundant RADIUS resources in each of their three geographical regions (AMER. EME
In the scenario provided, each of the clients in the three geographical regions (AMER, EMEA, and APAC) will require OnGuard licensing for health validation through a local agent, covering both wired and wireless authentications as well as personal device Wi-Fi authentication. Given the client counts range between 4,435 and 5,859 in each region, and assuming the upper limit for planning purposes, we have approximately 5,859 clients per region. Multiplying by three regions gives us 17,577, which would be rounded up to the nearest available licensing tier. In this case, 15,000 licenses would not be sufficient, so the next logical tier would likely be around 20,000 licenses. However, since this exact number isn't an option, and based on the principle of providing the most accurate and cost-effective solution, the best estimate with the given options would be 15,000, understanding that this might involve purchasing additional licenses to cover the exact needs.
You ate presenting your network design solution to your customer. What Is important to include in your presentation?
When presenting a network design solution to a customer, it is crucial to focus on the benefits that the solution will bring to their business. This includes both tangible returns, such as cost savings, increased efficiency, and improved performance, and intangible returns, such as enhanced security, scalability, and user satisfaction. Highlighting how the solution addresses the customer's specific needs and challenges, and how it aligns with their business objectives, helps in demonstrating the value of the solution and facilitates decision-making. Including tangible and intangible returns in the presentation makes it more compelling and relevant to the customer's business goals, thereby increasing the likelihood of the proposal's acceptance.
A customer wants to have the ability to show network usage. Which product would allow them to have this visibility?
Aruba Central provides a cloud-based management platform for managing and monitoring Aruba Instant APs, switches, and branch gateways. It offers a comprehensive dashboard that gives insights into network usage, health, and performance metrics.

This visibility into network usage is crucial for optimizing network performance, planning capacity, and understanding user behavior. Aruba Central's analytics and reporting capabilities enable customers to track and analyze network usage, making it the appropriate product choice for customers wanting to monitor their network usage closely.
'Don't Buy at Us' is a US-based retail company that is expanding Into Europe. They are expanding into EMEA with a regional headquarters called HQ2 inside The Netherlands.
Their US-based headquarters HQ1 was refreshed last year based on the Aruba ESP architecture. You have treated the design for HQ? based on the same design as HQ1. a two-tier architecture. The high level is shown below.
Switch BOM for this project based on Two Tier:
Collapsed Core: 2 x Aruba 8360-16Y2C in VSX (ISL 2 ICOG0E DAC)
Access Slack: 10 x Slack of Aruba 6200F 48G Class4 PoE 4SFP- 740W each stack has A members. VSF
with 10GbE VSF links) 12 x 10GbE uplink pet stack)
During the presentation of your design to the CTO of 'Don't Buy at Us' you were informed about the updated fiber infrastructure that Don't Buy at Us' has installed in HQ2.
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.
