What solution fits the customer’s requirements?

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 instant OS (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 on 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. For their POS systems, they need a low-latency network connection between the POS system and the POS server in the data center on the ship. Also, the CSO wants to enhance the WLAN security as well by tunneling all user traffic.

What solution fits the customer’s requirements?
A . Standardize on Aruba 6300 switches for the edge. 8325 for the RR. 8360 for the stub/border. 9240 for the WLAN Gateway, and utilize Aruba Central Net Conductor.
B . Standardize on Aruba 6300 switches for the edge. 8320 for the RR. 8360 for the stub/border, and utilize Aruba Central Net Conductor
C . Standardize on Aruba 6300 switches for the edge. 8320 for the RR. 8320 for the stub/border. 9240 for the WLAN Gateway, and utilize Aruba Central Net Conductor
D . Standardize on Aruba 6300 switches for the edge. 8320 for the RR. 8360 for the stub/border. 9240 for the WLAN Gateway, and utilize Aruba Central Net Conductor.
E . Standardize on Aruba 6200 switches for the edge. 8325 for the RR. 8360 for the stub/border, and utilize Aruba Central Net Conductor

Answer: D

Explanation:

Considering the global cruise line company’s requirement to enhance wired network security while ensuring low-latency connections for POS systems and tunneling all user traffic for WLAN security, the most fitting solution involves a combination of Aruba switches and gateway along with a network management and orchestration tool. Specifically, standardizing on Aruba 6300 switches for the edge layer caters to the need for high-performance, fan-less switches with 10GbE uplinks, matching the requirement for upgraded cabin and technical room connections. The Aruba 8320 as a Route Reflector (RR) and Aruba 8360 for the stub/border provide a robust core and distribution layer with high throughput and redundancy. The inclusion of a 9240 WLAN Gateway addresses the need for secure WLAN user traffic tunneling. Utilizing Aruba Central Net Conductor enhances network management efficiency, security policy enforcement, and dynamic segmentation across the wired and wireless infrastructure, aligning with the ESP architecture from Aruba and meeting the company’s security enhancement objectives.
