A customer wants to build a new data center based on the QFX3000-M. The data center must support 30 high traffic volume host servers. Each server will be dual connected to the fabric with two 40 Gbps links. The customer requires that there be a 1:1 subscription ratio within the fabric.
How should the QFX3000-M be configured to meet the customers requirements?

  • A. Use four QFX5100-24Q Interconnect chassis to which each of30QFX35000 nodes will be dual connected with two 40 Gbps FTE links to eachQFX5100-24Q.
  • B. Use four QFX3600-I Interconnect chassis to which each of eight QFX3600 nodes will be dual connected with two 40 Gbps FTE links to each QFX3600-I.
  • C. Use eight QFX3600-I Interconnect chassis to which each of 16 QFX3600 nodes will be connected with a 40 Gbps FTE link to each QFX3600-I.
  • D. Use four QFX3008-I Interconnect chassis to which each of 16 QFX3600 nodes will be dual connectedwith two 40 Gbps FTE links to each QFX3600-I.

  • A. Use LAG and establish a connection to a single access switch that is a member of a Virtual Chassis.
  • B. Use LAG and establish two connections to two different access switches.
  • C. Use MC-LAG and establish a connection to two different access switches in the same Virtual Chassis.
  • D. Use MC-LAG and establish a connection to two different access switches.
