Nutanix Certified Associate Practice Exam

What is necessary for ensuring applications have continuous availability in a multi-site Nutanix setup?

1. Uniform hardware across all clusters

2. Consistent application versioning between sites

3. Proper configuration of protection domains

4. Exclusive use of local block storage

The correct answer is: Proper configuration of protection domains

In a multi-site Nutanix setup, ensuring continuous availability for applications relies heavily on the proper configuration of protection domains. Protection domains are a key component in Nutanix's data protection strategy, as they define how data is replicated between clusters across different sites. By configuring these domains correctly, administrators can dictate the level of data redundancy and failover capabilities necessary for maintaining application availability even in the event of a site-level failure. This configuration allows for seamless failover processes and helps to mitigate the risk of downtime, thus ensuring that applications remain accessible. Protection domains not only facilitate data locality and enhance performance but also ensure that data integrity is sustained across multiple sites, providing the resilience needed for mission-critical applications. Uniform hardware across clusters, while beneficial for performance consistency, does not directly contribute to application availability. Similarly, consistent application versioning can enhance compatibility but is not a primary factor for continuous availability. Lastly, local block storage usage is not necessarily relevant in a multi-site environment that prioritizes high availability and data replication across sites. Therefore, proper configuration of protection domains is essential for achieving the continuous availability that multi-site setups aim to provide.
