Question 447

A company recently deployed new servers to create an additional cluster to support a new application. The corporate security policy states that all new servers must be resilient. The new cluster has a high-availability configuration for a smooth failover. The failover was successful following a recent power outage, but both clusters lost critical data, which impacted recovery time. Which of the following needs to be configured to help ensure minimal delays when power outages occur in the future?

    Correct Answer: A

    Replication is the correct answer. Replication ensures that data is copied and stored in multiple locations. This means that in the event of a power outage or other failure, the data can still be accessed from other servers or clusters that were not impacted. This setup reduces the risk of data loss and ensures minimal delays in recovery as the failover can access the replicated data swiftly, thereby improving the overall resilience of the system.

Discussion
isaphiltrickOption: A

Based on the requirement to reduce delays during power outages and the scenario's description of data loss despite high availability, configuring replication (option A) is crucial. Replication ensures that critical data is duplicated across clusters, allowing seamless failover and access to data from alternative locations in the event of server failures or power outages. This approach directly addresses the need for data resilience and continuity, ensuring minimal impact on operations during unforeseen disruptions. Thus, replication is the most suitable solution to enhance the company's data resilience and reduce recovery times during power outages.
