   A company is replacing its network equipment. The design team is comparing two models. Model A has a shorter lifespan but is made from recycled materials. Model B has a longer lifespan but uses virgin materials. The company wants to minimize the environmental impact over the equipment's lifecycle. Which factor should be the primary consideration in the lifecycle assessment?

   • AThe use of recycled materials in Model A, because it reduces the impact of manufacturing.
   • BThe purchase price of each model, because it reflects the environmental cost.
   • CThe longer lifespan of Model B, because it reduces the frequency of replacement and associated manufacturing and disposal impacts.
   • DThe energy efficiency rating of each model, because it is the most important factor.

   A campus network design must support a mix of high-bandwidth research applications and typical office traffic. The design team wants to reduce energy consumption without sacrificing performance. They are considering implementing Energy Efficient Ethernet (IEEE 802.3az) on all access switches. Which additional design measure would best complement this to reduce power consumption?

   • AEnable port aggregation (LACP) on all server connections to increase throughput.
   • BImplement a policy to power down unused switch ports and place idle devices into low-power mode.
   • CUse network virtualization to consolidate multiple virtual networks onto a single physical switch.
   • DUpgrade all access switches to models with higher port density to reduce the number of switches.
