Veeam Certification VMCA2022 Exam Questions and Answers PDF

If you separated the large VMDKs into their own backup jobs, you would be creating more manual work for the backup administrator, who would have to configure and maintain multiple jobs for the same group of VMs. This would go against the requirement of reducing administrative overhead by using dynamic scoping.

Dynamic scoping is a feature of Veeam Backup & Replication that allows you to automatically include or exclude VMs from backup jobs based on tags, attributes, or policies1. For example, you can use VMware tags to assign a backup policy to a VM, and then use the tag as a filter in the backup job. This way, any VM with that tag will be automatically added to the backup job, and any VM without that tag will be automatically excluded. This simplifies the backup management and ensures that all VMs are protected according to their assigned policy.

For large VMDKs with high I/O, you can use alternative backup methods to avoid performance impact and stuns, such as storage snapshots, direct SAN access, or hot-add2. You can also use different storage optimization options to balance the deduplication ratio and the backup file size3. These options can be configured within the same backup job, without the need to separate the large VMDKs.

You can find more information about dynamic scoping and backup methods for large VMDKs in the following resources:

The component sizing that should be adjusted is the physical storage in the repositories. The repositories are the backup storage locations where Veeam Backup & Replication stores backup files, VM copies and metadata for replicated VMs1. Increasing the retention period from four to five years means that more backup files will be kept on the repositories, and thus more storage space will be required. The other options are not affected by the retention period change, as they are either related to off-site backups (option A), Veeam Backup & Replication server performance (option C), or backup proxy performance (option D). References: Backup Repositories.

Changing the backup window from 12 hours to 14 hours means that the backup jobs will have more time to complete, and therefore less concurrency will be required. This will reduce the load on the proxies, which are the data movers that perform backup, replication, and restore tasks1. The proxies will need fewer resources, such as CPU and memory, to handle the same amount of data.

The other options are incorrect because:

• A) Proxies will not require more resources, as explained above.
• B) Mount servers will not require fewer resources, as they are not affected by the backup window. Mount servers are used to mount backup files and restore data from them2. Their resource consumption depends on the restore frequency and performance, not the backup window.
• D) Repositories will not require more storage space, as the backup window does not affect the backup size. Repositories are storage locations where the backup files are stored3. Their storage space consumption depends on the amount of data to be backed up, the backup method, the retention policy, and the compression and deduplication settings, not the backup window.

To design a solution that meets the needs and requirements of Veeam University Hospital, you need to gather some information during the discovery phase. This information will help you to understand the current state of the environment, the goals and expectations of the stakeholders, and the constraints and challenges of the project.

According to the Veeam Backup & Replication Best Practice Guide1, some of the information that is necessary for designing a solution and must be gathered during discovery are:

•Operating systems used to run the workloads. This information will help you to determine the compatibility and supportability of the workloads with Veeam products and features, as well as the licensing and configuration requirements.

•Allowed backup windows. This information will help you to plan and schedule the backup jobs according to the availability and performance of the workloads, as well as the service level agreements (SLAs) and recovery point objectives (RPOs) of the organization.

•Amount of used disk space. This information will help you to estimate the backup storage requirements, as well as the backup compression and deduplication ratios, based on the type and size of the data.
