You are gathering information to determine capacity, density, and scaling of systems for a campus switching design. What information is critical to the design? (Choose three.)

Question

Options

• Athe number of guest users or contractors accessing with a mobile hot spot
• Bthe number of unmanned IP-enabled end systems (e.g., HVAC, network printers, POS machines
• Cthe number of users with a fixed desktop station and attached IP phone
• Dthe number of physical VoIP phones not connected to a desktop
• Ethe number of users that are home office/mobile workers

• A
  8% (4)
• B
  78% (38)
• E
  14% (7)

Explanation

Options B, C, and D are correct because they represent wired, on-premises devices that permanently consume switch ports, IP addresses, and PoE capacity - exactly the fixed infrastructure a campus switching design must be sized for. A desktop station with an attached IP phone (C) typically requires two switch ports or a daisy-chained PoE phone, while standalone VoIP phones (D) each need their own port and PoE budget. Unmanned IP devices like HVAC controllers and printers (B) are often overlooked but are always-on and require dedicated ports and VLANs.

Why A and E are wrong: Guest users on mobile hotspots (A) and home/mobile workers (E) do not connect to the campus switching infrastructure - they use external cellular networks or VPN over the internet, so they place no demand on switch ports, PoE, or LAN capacity.

Memory tip: Think "wired walls" - only count devices physically plugged into a wall jack on campus. If a device bypasses your switches (hotspot, home office), it doesn't affect your switching design.
