A. B. C. D.B.
When agents are installed in the same data center as their associated endpoint, you can see an increase in data collection performance of 200 percent, on average.
The collection time measured includes only the time spent transferring data between the proxy agent and the manager service.
In a multisite environment where vRealize Automation (vRA) is deployed in one site and provisioning virtual machines through the vCenter server in another site, data collection performance can be improved by installing the appropriate component in the remote site.
There are two options mentioned in the answers:
A. Install DEM Workers to Site B B. Install Proxy Agent in Site B
Option A: Install DEM Workers to Site B
A Distributed Execution Manager (DEM) worker is a component in vRA that is responsible for running workflows, collecting data, and executing other tasks related to machine provisioning. Installing a DEM worker in the remote site can improve data collection performance because it reduces the amount of network traffic between the vRA server and the remote vCenter server.
However, this option alone may not be sufficient to improve data collection performance, as it only addresses one aspect of the data collection process.
Option B: Install Proxy Agent in Site B
A Proxy Agent is a component in vRA that is responsible for collecting data from vCenter servers and other endpoints. Installing a Proxy Agent in the remote site can improve data collection performance by reducing the amount of network traffic between the vRA server and the remote vCenter server, as well as reducing the number of API calls made to the remote vCenter server.
Option B is the better choice in this scenario, as it addresses both aspects of the data collection process (i.e., reducing network traffic and API calls). By installing a Proxy Agent in Site B, the vRA server can collect data from the remote vCenter server more efficiently, resulting in improved data collection performance.
Therefore, the correct answer is B. Install Proxy Agent in Site B.
