Answer(s): D



You have a customer using Spine and Leaf design with two 8325 32-port 100G QSFP28 (F-B airflow) Spine Switches.
What is the maximum number of racks supported if each Rack has two 8360 VSX stacked leaf switches and each spine uses 2 x 100G QSFP28 DACs to each Leaf switch?

  1. Up to 16 total racks using different subscription rates
  2. Up to 4 total racks using the same subscription rates
  3. Up to 4 total racks using different subscription rates
  4. Up to 8 total racks using the same subscription rates

Answer(s): D



In a Spine and Leaf Design with the following specs:
· 8400 100G Spine Switches
· 8360 48-P 10G RJ45 Leaf Switches
· 100G DAC connections between Spine and Leafs
Spine Switches = 8400 with 12 QSFP28 ports (F-B airflow)

Each Spine Switch uses:
· 1 x 100G QSFP28 5M DACs to each Leaf switch
Each Leaf Switch uses:
· 1 x 100G QSFP28 5M DACs to each Spine switch
· 2 x 100G 1M DAC for ISL
· 1 x 10G RJ45 for Keep alive
Each Spine switch can support up to 48 available 100G QSFP28 interfaces.
What is the scalability for this solution?

  1. Solution can scale to 24 total racks using the same subscription rates.
  2. Solution can scale to 6 total racks using the same subscription rates.
  3. Solution can scale to 12 total racks using the same subscription rates.
  4. Solution can scale to 48 total racks using the same subscription rates.

Answer(s): A



In L3 spine and leaf design

  1. Spanning Tree is always needed since Spine and Leaf is only there to improve performance
  2. You need to use TRILL to prevent loops
  3. You don't need to use spanning tree for loop prevention
  4. Since all Spine switches are connected to each other, EVPN is needed in this design
