   A company is designing a new data center network to support a mix of traditional client-server applications and a growing number of distributed applications that communicate heavily between servers. The design team wants to ensure that the network can scale to accommodate increased east-west traffic without requiring a major redesign. Which design approach best meets this requirement?

   • AConnect all servers in a full mesh topology using direct cabling between each server.
   • BDeploy a three-tier architecture with core, aggregation, and access layers, and place all servers in the access layer.
   • CUse a single large chassis switch in the core and connect all servers directly to it.
   • DImplement a spine-and-leaf architecture with every leaf switch connected to every spine switch, and place servers on leaf switches.

   A company is designing a data center in a region with high energy costs. The design team must choose between two cooling strategies: (1) a traditional air-cooled system with hot/cold aisle containment, or (2) a liquid-cooled system with rear-door heat exchangers. The liquid-cooled system has a higher upfront cost but lower ongoing energy consumption. Which strategy is more cost-effective over the long term?

   • AStrategy 2, because the lower energy consumption will offset the higher upfront cost over time.
   • BStrategy 1, because it is more reliable and has a longer lifespan.
   • CStrategy 1, because it has lower upfront costs and is simpler to maintain.
   • DStrategy 2, because it requires less maintenance.

   A data center is being built in a region with a hot climate and limited water supply for cooling. The design team must choose a cooling approach that minimizes water usage while maintaining acceptable temperatures. Which cooling strategy is most appropriate?

   • AFree cooling using outside air only.
   • BLiquid cooling with a closed-loop system.
   • CEvaporative cooling using a cooling tower.
   • DAir-based cooling with hot/cold aisle containment.

   A data center network team is designing a network for a web application that receives user requests from the internet and processes them using a cluster of application servers. The application servers also communicate with a database cluster for data retrieval. Which statement best describes the primary traffic patterns in this design?

   • ANorth-south traffic is the only traffic pattern, as user requests come from the internet.
   • BBoth north-south and east-west traffic patterns are present, with north-south at the edge and east-west between servers.
   • CNeither pattern is present because the application is hosted in the cloud.
   • DEast-west traffic is the only traffic pattern, as servers communicate with each other.

   A data center network team is planning to deploy a new analytics platform that will process large datasets stored on multiple servers. The analytics jobs will require frequent data shuffling between servers. The team wants to minimize latency for these inter-server communications. Which network design characteristic is most important to achieve this goal?

   • AHigh-speed uplinks from access switches to the core.
   • BA flat, low-latency topology such as spine-and-leaf.
   • CA large number of VLANs to segment traffic.
   • DA centralized firewall for all inter-server traffic.
