   A data center network team is designing a network for a high-performance computing (HPC) cluster that requires extremely low latency for inter-process communication. The cluster nodes are spread across multiple racks. Which network design is most appropriate?

   • AA ring topology connecting all nodes in a loop.
   • BA single large switch with all nodes connected directly.
   • CA traditional three-tier architecture with a core, aggregation, and access layers.
   • DA spine-and-leaf architecture with all nodes connected to leaf switches.

   A data center network team is planning to deploy a new storage area network (SAN) that will be used for backup and recovery. The SAN traffic is expected to be predominantly east-west, with large data transfers between storage arrays and backup servers. Which network design consideration is most important for this workload?

   • AEnsure the network uses a traditional three-tier architecture to contain traffic.
   • BEnsure the network provides high-bandwidth, low-latency paths between storage and backup servers.
   • CEnsure the network has a strong perimeter firewall to protect against external threats.
   • DEnsure the network uses a single VLAN to simplify management.

   A data center network team is designing a network for a video streaming service. The service receives user requests from the internet and streams video content from servers located in the data center. The team wants to optimize the network for this workload. Which traffic pattern is most critical to optimize?

   • ANorth-south traffic, because user requests and video streams traverse the internet edge.
   • BBoth equally, because the workload is balanced.
   • CEast-west traffic, because servers communicate with each other to process requests.
   • DNeither, because the workload is not traffic-intensive.
