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 10GbE 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 quest 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 best practices, what should you recommend as the correct optic type for the connection between the IDF and the technical rooms?

• A. Aruba 10G SFP+ LC SR 300 m MMF Transceiver
• B. Aruba 10G LC BiDi 40 km-D 1330/1270 XCVR
• C. Aruba 10G SFP- LC LRM 220 m MMF Transceiver
• D. Aruba 10GBASE-T SFP- RJ-45 30 m Cat6A Transceiver

The current IT staff is used to working with legacy OS-S (ProCurve) equipment. They are worried that they cannot handle OS-CX switches due to the different command syntax. What are two ways to make the transition easier for them? (Choose two.)

• A. CLI Bank
• B. ASP
• C. create aliases
• D. CLI Reference Guide for OS-CX, OS-Switch, Comware and Cisco IOS

Drag and Drop Question
Match the Wi-Fi features to their appropriate standard. (Some matches may be used more than once.)

What is the simple difference between a main distribution framework (MDF) closet and an intermediate distribution framework (IDF) closet?

• A. MDFs only connect to other MDFs, and IDFs only connect to other IDFs.
• B. MDF is the point where traffic egresses the campus network, and IDFs distribute that connectivity throughout the building.
• C. MDF is a term used in Europe whereas the Americas refer to all network closets as IDFs in their documentation.
• D. MDFs always have larger rooms than IDFs.

What is the primary purpose of conducting stakeholder interviews during the discovery phase of a network design project?

• A. To select appropriate network hardware
• B. To determine the budget constraints
• C. To understand the organizational goals and requirements
• D. To configure network devices
