Veeam Certification Changed VMCA2022 Questions

The number of vSphere clusters and the total of virtual machines are important information related to the virtual infrastructure that are missing and must be collected during the discovery phase. These information can help you estimate the backup performance, scalability, and resource requirements for the Veeam backup infrastructure. For example, you can use the number of vSphere clusters to determine how many Veeam backup servers and proxies you need to deploy and how to distribute the backup load among them. You can also use the total of virtual machines to calculate the total amount of data to be backed up, the storage space required, and the network bandwidth needed.

The areas that would benefit from additional analysis on areas mentioned in the case study are MSSQL, NAS, and PostgreSQL. These areas have specific backup and restore requirements that need to be considered and addressed in the design and sizing of the Veeam backup infrastructure. For example, MSSQL requires transaction log backup and application-aware processing to ensure consistent backups and point-in-time recovery. NAS requires file-level backup and storage integration to optimize backup performance and storage efficiency. PostgreSQL requires pre-freeze and post-thaw scripts to quiesce the database before backup and resume it after backup.

A possible issue that could arise if you put the backup repositories in the backup network only is that laptop agents cannot communicate with the repository. This is because laptop agents are not part of the backup network, which is non-routable according to the existing technical environment.Therefore, laptop agents cannot access or write data to the backup repositories in the backup network unless there is a proxy or gateway server that can bridge the communication between them.

The information related to sizing the NAS infrastructure that is missing and must be collected during the discovery are the size of the source data set and the recovery point objective (RPO). These information are important for designing and sizing the NAS backup jobs and repositories. For example, you can use the size of the source data set to estimate how much storage space and network bandwidth are required for backing up NAS devices. You can also use the RPO to determine how frequently you need to run NAS backup jobs and how many restore points you need to keep on the backup repositories.
