   A hospital is planning a new data center for its electronic health record (EHR) system. The system is mission-critical and requires high availability. The hospital has a limited budget and a small IT team that is experienced with traditional hierarchical networks. The EHR application is primarily accessed by staff from the hospital's LAN, with some remote access via VPN. The expected growth is low. Which topology is the most appropriate?

   • AA fabric architecture using VXLAN and BGP EVPN
   • BSpine-leaf with full redundancy and ECMP
   • CThree-tier with redundant core and aggregation switches
   • DA single access switch with all servers connected directly

   What is the primary purpose of a data center network topology?

   • ATo determine the number of IP subnets required in the data center
   • BTo define the physical layout of servers and storage devices
   • CTo specify the routing protocol used between data center switches
   • DTo establish the logical and physical interconnection pattern of network devices to support data flow and services

   A data center architect is evaluating different topologies for a new facility. The facility will host a mix of applications, including some that require low latency and others that are less sensitive. The architect wants to choose a topology that provides consistent performance and is easy to scale. Which topology should be recommended?

   • ASpine-leaf
   • BBus
   • CThree-tier
   • DRing

   A data center architect is designing a spine-leaf network. Each leaf switch will connect to two spine switches. To ensure that traffic is distributed across both uplinks and that a link failure does not cause an outage, which mechanism should be used?

   • ALink aggregation (LACP) to bundle both uplinks into a single logical link
   • BSpanning Tree Protocol (STP) with one uplink in blocking mode
   • CEqual-cost multi-path (ECMP) routing
   • DVirtual Router Redundancy Protocol (VRRP) for gateway redundancy
