   Why is environmental sustainability relevant to network design?

   • ABecause sustainable networks are always less expensive to build and operate.
   • BBecause environmental regulations require all network designs to achieve carbon neutrality.
   • CBecause network equipment is the largest consumer of electricity in most data centers.
   • DBecause network design decisions influence energy consumption, material use, and e-waste over the network's lifetime.

   A network architect is evaluating two switch models for a large enterprise refresh. Model X has a lower purchase price but a higher power draw and a shorter expected lifespan. Model Y has a higher purchase price but is more energy-efficient and has a longer lifespan. The company wants to minimize the total environmental impact over a 10-year period. Which approach best supports a lifecycle assessment (LCA) decision?

   • AChoose Model Y only if it is certified as Energy Star, otherwise choose Model X.
   • BChoose Model X because the lower purchase price reduces the financial cost, which is the primary business driver.
   • CChoose Model X because it will be replaced sooner, allowing the company to adopt newer, more efficient technology earlier.
   • DChoose Model Y because its longer lifespan and lower energy consumption reduce the environmental impact over the 10-year period.

   A global enterprise is developing its five-year IT strategy. The CIO wants to integrate environmental sustainability into the network design strategy. The company has a goal to reduce its carbon footprint by 30% by 2030. Which approach best integrates sustainability into the business strategy?

   • ASet a policy that all new network equipment must be Energy Star certified.
   • BIncorporate carbon footprint reduction targets into the network design requirements and review them at each design phase.
   • CPurchase carbon offsets to compensate for the network's emissions.
   • DCreate a sustainability task force that meets quarterly to discuss green initiatives.
