HPE7-A03 Question #30: Real Exam Question with Answer & Explanation

A German 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 (Ship One) with a maximum of 350 guests. Ship One has a LAN infrastructure consisting of two core switches, eight redundant distribution switches, and two hundred access switches (175 cabins and 25 technical rooms). The Core switches are located in the MDF of the ship, the distribution switches are located in the IDFs (eight in total) of the ship. Each cabin and technical room gets one single access switch. The structured cabling of the ship will not be refreshed. Each IDF is connected to the MDF by SMF pairs. Each cabin is connected by a single MMF pair to the IDF. Each technical room is connected by a single MMF pair to the IDF. 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 10GbE to handle the increased network traffic. The WLAN infrastructure will be 1:1 refreshed without new cabling or new AP locations. Their WLAN infrastructure is based on the 200 series indoor and outdoor APs running InstantOS (total of 195 APs), the customer has no change in WLAN requirements. Your team member (out on parental leave) has started with the proposed solution listed below. Core switch: one VSX stack of two 8325-48Y8C switches Distribution switch: one VSF stack of two 6300F 24-port SFP+ and 4-port SFP56 switches per IDF Cabin switch: one 6200F 12G Class4 PoE 2G/2SFP+ per cabin Technical room switch: one 6200F 12G Class4 PoE 2G/2SFP+ per technical room Indoor Cabin APs: AP-505H (88 total) Indoor standard APs: AP-535 (82 total) Outdoor APs: AP-565 (25 total) What possible issue with the core switch selection do you see in regards to the customer's requirements?
