Quiz: Using 10 Gigabit Ethernet in your data center

10 Gigabit Ethernet (10 GbE) allows networking pros to build bigger, faster and more resilient networks. But there are challenges. Network and data center managers must ensure that each system and application on the network has the bandwidth and quality of service it needs while maintaining interoperability and avoiding bottlenecks. But with knowledge in hand you'll understand how 10 GbE can improve your data center network by introducing flexibility and preventing latency while enabling data and storage network convergence.

This quiz tests what you know about 10 Gigabit Ethernet. Answer these questions correctly and you will be on your way to ensure that you understand the choices to make when it comes to designing and managing your data center and its connections.

1. What is TRILL? *

An alien symbiote from Star Trek
A protocol that enables mesh networks with all links active replacing Spanning Tree
A protocol for converging storage and data
A protocol for making Ethernet lossless

2. What are cable options for FCoE? *
