Correct Answer: B
* The question asks about the benefit of the spine-and-leaf network topology, which is a data center network design that consists of two layers of switches: the spine layer and the leaf layer. The spine layer interconnects all the leaf switches in a full-mesh topology, and the leaf layer connects to the servers and end devices1.
* The answer is stable network latency, which means the delay or time it takes for a packet to travel from one point to another in the network. In a spine-and-leaf topology, every leaf switch is the same number
* of hops away from any other leaf switch, which ensures consistent and predictable latency for the traffic between the servers and devices2. This is especially important for applications that require high performance and low latency, such as cloud computing, big data analytics, and virtualization3.
* Increased network security, simplified network management, and eliminated need for inter-VLAN routing are not the correct answers, because they are not the benefits of the spine-and-leaf topology.
Increased network security depends on other factors, such as encryption, authentication, and firewall policies, not just the network topology. Simplified network management may be achieved by using automation and orchestration tools, but the spine-and-leaf topology itself may require more cabling and configuration than a traditional three-tier topology. Eliminated need for inter-VLAN routing is not a benefit, because inter-VLAN routing is still needed to communicate between different VLANs or subnets in the network, regardless of the topology.
