To accommodate additional architectural changes and a horizontal cross-connect, the Equipment Room size is adjusted to which area?

• A. 12 sq m
• B. 18 sq m
• C. 20 sq m
• D. 25 sq m

Answer: (B)

When planning an Equipment Room, you must size it to support the equipment layout and cabling for the cross-connects, plus any architectural changes. Adding a horizontal cross-connect and related changes means you need enough floor area to place multiple 19-inch racks with proper front and rear clearance, plus space for patch panels, cable trays, and a service aisle. About 18 square meters provides that workable footprint: it accommodates the racks and the necessary clearances for safe access and reliable interconnection between the main equipment and the horizontal cross-connect without wasteful excess space. A smaller space would be cramped and hinder maintenance, while larger footprints would be more than needed for this configuration.
