   A small business is deploying a data center for its ERP system. The network will have a core switch, two distribution switches, and several access switches. The traffic is mostly north-south, and the business does not anticipate significant growth. What is the primary advantage of this three-tier design over a spine-leaf design?

   • AMore efficient use of uplink bandwidth
   • BSimpler to operate for teams familiar with hierarchical designs
   • CBetter scalability for large-scale data centers
   • DLower latency for east-west traffic

   What is a primary benefit of the spine-leaf topology compared to traditional three-tier designs?

   • AReduced need for link aggregation because each link is faster
   • BSimpler management because all switches are in a single layer
   • CLower cost due to fewer switches required
   • DPredictable low latency because traffic traverses the same number of hops between any two leaf switches

   A legacy data center uses a three-tier topology. The organization is planning to deploy a new analytics platform that generates heavy east-west traffic between servers. The network team is considering whether to migrate to spine-leaf or to keep the three-tier design. What is the most important factor in this decision?

   • AThe familiarity of the network team with three-tier designs
   • BThe cost of new switches and cabling
   • CThe need to support legacy north-south traffic
   • DThe ability to provide low-latency, high-bandwidth paths for east-west traffic

   A cloud provider is designing a new data center to host multi-tenant virtualized workloads. The workloads generate unpredictable east-west traffic, and the provider needs to scale capacity by adding racks without redesigning the network. Which topology should be selected?

   • AA ring topology connecting all switches in a loop
   • BA single large chassis switch at the core
   • CThree-tier with a collapsed core
   • DSpine-leaf with equal-cost multi-path (ECMP) routing
