   What is the purpose of link aggregation in a data center topology?

   • ATo route traffic between different subnets
   • BTo encrypt traffic between switches
   • CTo combine multiple physical links into a single logical link to increase bandwidth and provide redundancy
   • DTo create a virtual LAN that spans multiple switches

   A university is upgrading its campus data center, which hosts a mix of administrative systems and research workloads. The existing network uses a three-tier design, and the IT team is familiar with its operation. The budget is limited, and the primary traffic pattern is north-south, with occasional east-west traffic between research clusters. The university expects modest growth over the next five years. What is the most appropriate approach?

   • AMigrate to a spine-leaf topology to future-proof the network
   • BReplace the core layer with a single high-capacity switch to simplify the network
   • CImplement a fabric architecture using VXLAN to improve east-west traffic
   • DKeep the three-tier topology and add redundancy at the aggregation layer

   What is a key design consideration when comparing three-tier and spine-leaf topologies?

   • ASpine-leaf scales more easily than three-tier because adding capacity only requires adding leaf or spine switches
   • BThree-tier is more cost-effective than spine-leaf for small data centers because it uses fewer switches
   • CSpine-leaf requires more cabling than three-tier, making it unsuitable for large data centers
   • DThree-tier provides lower latency than spine-leaf because it has fewer hops
