L2LS - Spine Redundancy Flashcards
What is the purpose of spine redundancy in data center networks, and how does it contribute to network availability?
Answer: Spine redundancy involves having two or more spine switches in a datacenter network. Its purpose is to provide failover capability and high availability. In the event of a spine switch failure, traffic can seamlessly shift to the remaining spines, ensuring uninterrupted network service and minimizing downtime.
Explanation: This question evaluates the candidate’s understanding of the importance of spine redundancy in maintaining network availability and fault tolerance.
Can you describe a scenario where spine redundancy plays a crucial role in ensuring network resilience in a data center?
Answer: Spine redundancy is particularly critical in scenarios where network continuity is paramount, such as large-scale e-commerce platforms or cloud service providers. In these cases, if one spine switch experiences a hardware failure or requires maintenance, the redundant spine switches maintain network operations, preventing service disruptions.
Explanation: This question tests the candidate’s ability to provide a real-world example of the practical significance of spine redundancy in ensuring network reliability.
