A network engineer is measuring the transfer of bits across the company backbone for a mission critical database application. The engineer notices that the network throughput appears lower than the bandwidth expected. Which three factors could influence the differences in throughput? (Choose three.)

• the amount of traffic that is currently crossing the network
• the sophistication of the encapsulation method applied to the data
• the type of traffic that is crossing the network
• the latency that is created by the number of network devices that the data is crossing
• the bandwidth of the WAN connection to the Internet
• the reliability of the gigabit Ethernet infrastructure of the backbone
  

  Explanation: Throughput usually does not match the specified bandwidth of physical links due to multiple factors. These factors include, the amount of traffic, type of traffic, and latency created by the network devices the data has to cross.
