An administrator is planning the size of a new vRealize Operations Manager (vROps) platform using the vROps sizing tool. The output of different configurations and sizing information from the tool were modeled for internal design discussion.

Refer to the exhibit:

Which configuration was sized?

A.
High Availability
Answers
A.
High Availability
B.
Continuous Availability
Answers
B.
Continuous Availability
C.
Stretched Cluster
Answers
C.
Stretched Cluster
D.
Fault Tolerance
Answers
D.
Fault Tolerance
Suggested answer: A

Explanation:

The configuration that was sized using the vROps sizing tool is High Availability.High Availability is a feature of vRealize Operations that allows the cluster to tolerate the failure of one or more nodes, and to ensure the continuity and availability of the vRealize Operations services1.High Availability can be enabled or disabled in the Admin UI of vRealize Operations, and it requires at least two nodes in the cluster2.The vROps sizing tool is a web-based tool that helps the administrator to estimate the size and the resources needed for a vRealize Operations deployment, based on the number and the type of the objects to be monitored3. The vROps sizing tool provides different sizing options, such as Extra Large, Large, Medium, Small, and Extra Small, and shows the specifications and the costs for each option.The vROps sizing tool also allows the administrator to select the configuration mode, such as High Availability, Continuous Availability, Stretched Cluster, or Fault Tolerance, and shows the impact of the mode on the sizing and the resources4. The image that was sent with the question shows the output of the vROps sizing tool, with the configuration mode set to High Availability. The image shows the recommended size as Medium, with 2 nodes, 5564 metrics, and 980812 properties. The image also shows the other sizing options, such as Extra Large, Large, Small, and Extra Small, with their respective specifications and costs. Therefore, the configuration that was sized using the vROps sizing tool is High Availability.Continuous Availability (option B) is not the correct answer, as it is a different configuration mode that allows the cluster to tolerate the failure of an entire site, and to ensure the zero data loss and the near-zero downtime of the vRealize Operations services5. Continuous Availability requires at least four nodes in the cluster, and it uses synchronous replication between the sites. The image does not show the configuration mode as Continuous Availability, nor the number of nodes as four. Stretched Cluster (option C) is not the correct answer, as it is a different configuration mode that allows the cluster to span across two sites, and to ensure the load balancing and the disaster recovery of the vRealize Operations services. Stretched Cluster requires at least four nodes in the cluster, and it uses asynchronous replication between the sites. The image does not show the configuration mode as Stretched Cluster, nor the number of nodes as four. Fault Tolerance (option D) is not the correct answer, as it is not a configuration mode that is supported by vRealize Operations. Fault Tolerance is a feature of vSphere that provides continuous availability for a virtual machine by creating and maintaining a secondary virtual machine that is identical to the primary virtual machine. Fault Tolerance is not applicable to vRealize Operations, as it does not support the clustering and the scalability of the vRealize Operations nodes.References:
