Correct Answer: C, EReplication jobs, in the context of Veeam DataLabs, offer several benefits for creating a test environment. Firstly, with replication jobs, the VMs are running directly on a high-performance datastore, uncompressed. This allows for better performance as compared to backup jobs which might involve deduplication or compression of data, impacting the efficiency of the test environment. Secondly, replicas can take advantage of advanced multi-host virtual labs, which allow for a more sophisticated and multi-dimensional testing environment. This is crucial for testing large, multi-VM applications as it ensures that the testing can leverage the resources of a dedicated VMware ESXi cluster more effectively.
