In a spine-leaf topology, how is high availability typically achieved?

By using a spanning tree protocol to block redundant links

By configuring all switches in a single broadcast domain

By using a single spine switch with redundant power supplies

By connecting each leaf switch to multiple spine switches and using multi-pathing protocols

A data center architect is explaining to a junior engineer the difference between a spine-leaf topology and a three-tier topology. Which statement is accurate?

Spine-leaf provides a maximum of two hops between any two leaf switches, while three-tier may require more hops.

Spine-leaf uses a single layer of switches, while three-tier uses two layers.

Spine-leaf is only suitable for small data centers.

Three-tier is always more scalable than spine-leaf.

A network engineer is configuring a spine-leaf fabric. Each leaf switch has two 40GbE uplinks to two different spine switches. The engineer wants to ensure that if one uplink fails, traffic is automatically rerouted to the other uplink without manual intervention. Which feature should be enabled?

Equal-cost multi-path (ECMP) routing

Link Aggregation Control Protocol (LACP)

Rapid Spanning Tree Protocol (RSTP)

A data center is being designed with a spine-leaf topology. The architect wants to ensure that if a spine switch fails, the impact is minimized. Which design consideration is most important?

Using a single, high-capacity spine switch

Connecting each leaf to at least two spine switches

Placing all spine switches in the same rack

Using a single link from each leaf to the spine layer

A large e-commerce company is building a new data center. The workloads are a mix of web servers (north-south traffic) and a distributed database (east-west traffic). The company expects to double its server count every two years. The network team is experienced with both three-tier and spine-leaf designs. Which topology should be chosen?

A collapsed-core design with two large switches

Three-tier with a high-capacity core

A ring topology to reduce cabling costs
