A data center currently uses a three-tier architecture. The network team is evaluating a move to spine-leaf to improve east-west traffic. The data center also connects to a WAN for remote office access. Which trade-off must be considered when moving to spine-leaf?

Spine-leaf eliminates the need for a WAN because all traffic stays local

Spine-leaf provides better north-south performance than three-tier

Spine-leaf reduces the number of switches needed, simplifying the network

Spine-leaf improves east-west performance but may require redesigning WAN edge connectivity because the spine layer typically does not host WAN routers

A data center is being designed to host a large number of virtual machines that communicate heavily with each other. The design must provide predictable latency and avoid oversubscription. Which topology characteristic is essential?

All traffic must pass through a central core switch

Every access switch connects to a single distribution switch

Every leaf switch connects to every spine switch

All switches are connected in a ring

A company is designing a hybrid cloud architecture. They have an on-premises data center and plan to use a public cloud for bursty workloads. The on-premises network uses a spine-leaf topology. The company needs to connect the on-premises data center to the cloud with low latency and high bandwidth. Which connectivity option is most appropriate?

A site-to-site VPN over the internet

A hub-and-spoke WAN with the cloud as a spoke

A full-mesh WAN between the cloud and all on-premises switches

A dedicated private connection such as AWS Direct Connect or Azure ExpressRoute
