All VMCA2022 Test Inside Veeam Questions

The best option to still satisfy the requirement for offsite, immutable or air gapped backups if the cloud provider selected for archive storage does not support immutability is to set up Scale-out Backup Repository capacity tier to a different cloud provider than the archive tier. Scale-out Backup Repository is a logical entity that groups several backup repositories into a single pool of storage, and allows to move backup files between performance and capacity tiers1. The capacity tier can be configured to use Amazon S3 or Microsoft Azure Blob Storage, which support Object Lock feature for immutability2. By using a different cloud provider for the capacity tier than the archive tier, the backup data can be stored in two separate locations, with one copy being immutable or air gapped. The other options are either not feasible (option A, as the scenario does not mention another site), not secure (option C, as the backup data can still be accessed or modified when the repository is online), or not offsite (option D, as the scenario requires a copy of backup data in a public cloud). References: Scale-out Backup Repository, Object Storage Immutability.

The tiers of Veeam Financial Services’ backups that will require SureBackup jobs are the silver and gold tiers. SureBackup jobs are used to verify the recoverability of backup files by running virtual machines from backups in an isolated environment and performing tests against live applications1. This feature is suitable for the silver and gold tiers, which have recovery time objectives of six hours and 30 minutes, respectively, and require backups to be verified. The bronze tier, which consists of development machines and field portables, has a recovery point target of seven days, with no recovery time target set, and does not require backup verification. Therefore, SureBackup jobs are not necessary for the bronze tier. Laptop backups are performed by Veeam Agent for Microsoft Windows, which does not support SureBackup jobs2. References: SureBackup, Veeam Agent for Microsoft Windows.

The information related to the virtual infrastructure that is missing and must be collected during the discovery are the total number of virtual machines and the size of the source data set. These are essential metrics for sizing the backup components, such as proxies, repositories, and transporters, as well as estimating the backup storage requirements and bandwidth consumption. The other options are either already provided in the scenario (recovery time objective, backup window) or not relevant for the Veeam solution (speed of Fibre Channel fabric). References: Veeam Certified Architect 2022 Exam Guide, page 10; Veeam Backup & Replication v11: Architecture and Design course, module 3.

Reducing the recovery point objective (RPO) for silver tier workloads means that the backup frequency will increase, resulting in more backup data being generated and transferred. This will affect the sizing requirements of the Veeam components that are responsible for storing and processing the backup data, namely the Veeam repository and proxy roles1.

The Veeam repository is a storage location where the backup files are stored. The repository size depends on the amount of data to be backed up, the backup method, the retention policy, and the compression and deduplication settings2. Reducing the RPO will increase the amount of data to be backed up, and may require more frequent synthetic full backups or active full backups to maintain the retention policy. This will increase the repository size and the disk space consumption.

The Veeam proxy is a data mover that performs backup, replication, and restore tasks. The proxy size depends on the number of concurrent tasks, the transport mode, the backup method, and the compression and deduplication settings3. Reducing the RPO will increase the number of concurrent tasks and the amount of data to be processed by the proxy. This will increase the proxy size and the CPU and memory consumption.
