A customer is planning to setup a new vRealize Operations environment using the following infrastructure:

There is one physical location.

This location has a few vCenter Servers.

These vCenter Servers will be monitored through vRealize Operations.

The customer wants to tolerate only one vRealize Operations node failure without losing any data in this vRealize Operations cluster.

Which vRealize Operations cluster feature must be used for this requirement?

A.
Remote Collector

D.
Stretched Cluster
Answers
D.
Stretched Cluster
Suggested answer: B

Explanation:

According to the VMware vRealize Operations Reference Materials, the High Availability feature in vRealize Operations cluster must be used for this requirement. The High Availability feature enables the cluster to tolerate one node failure without losing any data or functionality. The High Availability feature works by creating a replica node for each data node in the cluster, and synchronizing the data between them. The replica node acts as a standby node that can take over the role of the data node in case of a failure. The replica node can also serve as a load balancer to distribute the workload among the data nodes. The other options are incorrect because they do not meet the requirement or they are not supported by vRealize Operations. The Remote Collector option is not a cluster feature, but a type of node that can be used to collect data from remote sources and forward it to the cluster. The Remote Collector node does not store any data or perform any analysis, and it cannot replace a data node in case of a failure. The Continuous Availability option is a cluster feature that enables the cluster to tolerate multiple node failures without losing any data or functionality. However, the Continuous Availability feature requires at least two physical locations, and it is not supported for a single location. The Stretched Cluster option is not a cluster feature, but a configuration that allows a cluster to span across two physical locations. The Stretched Cluster option can provide high availability and disaster recovery, but it also requires additional network and storage configuration, and it is not supported for a single location.References:vRealize Operations Cluster and Node Maintenance;Adding High Availability to vRealize Operations;Adding Continuous Availability;Stretched Cluster
