Suggested answer: A, C

Explanation:

An Events Service cluster is a group of two or more Events Service nodes that work together to store and process unstructured data generated by AppDynamics components such as Application Analytics, Database Visibility, and End User Monitoring1.Using an Events Service cluster has two main advantages over a single-node instance12:

Clusters allow data replication across multiple nodes. This means that the data is duplicated and distributed among the nodes in the cluster, providing data redundancy and protection against data loss in case of a node failure. Data replication also improves data availability and query performance, as the cluster can handle concurrent requests from multiple clients.

Clusters are horizontally scalable by adding nodes. This means that the cluster can grow in size and capacity by adding more nodes to the cluster, without affecting the existing nodes or data. Horizontal scaling allows the cluster to handle increasing data volumes and performance demands, as well as balance the workload among the nodes.Reference:Events Service Deployment,What are the Benefits of Server Clustering?
