VMCE2021 Veeam Certified Engineer 2021 Questions and Answers

To achieve the RPO of eight hours, the replication jobs must be able to transfer 300 GB of data within that time frame. The available bandwidth is 40 Mbps, which means that the maximum amount of data that can be transferred in eight hours is about 144 GB (40 Mbps x 8 hours x 60 minutes x 60 seconds / 8 bits). Therefore, the replication jobs need to reduce the amount of data that needs to be transferred by using some compression or deduplication techniques. The best option for this scenario is to use WAN acceleration, which is a feature of Veeam Backup & Replication that optimizes data transfer over WAN or slow connections. WAN acceleration uses global data deduplication, caching, and compression to reduce the amount of data sent over the network and speed up the replication process. According to Veeam’s documentation1, WAN acceleration can reduce the amount of data transferred by up to 50 times and increase the data transfer speed by up to 20 times. Therefore, by using WAN acceleration, the replication jobs can easily achieve the RPO of eight hours.

The other options are not as effective as this one. Option A uses replication jobs with copy mode set to “Interval copy”, which is a new mode introduced in Veeam Backup & Replication v10 that copies restore points as soon as they appear in the source backup repository. However, this option does not use any compression or deduplication techniques, and it also depends on the backup job schedule, which may not match the RPO requirement. Option B uses replication jobs with copy mode set to “periodic copy”, which is the traditional mode that copies the latest source restore point according to a specified interval. However, this option also does not use any compression or deduplication techniques, and it may miss some restore points if there are network outages or failures. Option C uses replication jobs set to Direct Mode, which is a mode that replicates VMs directly from the source host without using any backup repository. However, this option also does not use any compression or deduplication techniques, and it may cause additional load on the source host and network. References:

Veeam ONE can help notify you of suspicious activity in your datacenter through the Possible Ransomware Activity alarm. This alarm can be configured to take mitigating actions such as sending an email notification, running a script or creating a support case.

According to the Veeam Agent for Microsoft Windows User Guide1, you need to enable application-aware processing to ensure quiescence of the SQL databases during the backup. Application-aware processing allows Veeam Agent for Microsoft Windows to create transactionally consistent backups of SQL Server VMs.

According to the Veeam Backup & Replication best practice guide1, a new copy job mode was added called immediate copy. This mode immediately starts the backup copy job as soon as restore points appear in the repository. It also provides the ability to copy SQL and Oracle log backups which is not possible with traditional periodic backup copy12.

Therefore, if you want to create a secondary copy of all the backups including transaction logs, you should use an immediate copy backup copy job. The simplest configuration would be a single immediate copy backup copy job for all workloads (option B)

According to the Veeam Backup & Replication user guide12, WAN acceleration is a technology that optimizes data transfer to remote locations by performing deduplication and caching. It is specific for off-site backup copy jobs and replication jobs12.

Therefore, if you want to achieve the RPO of six hours with 500 GB of data and 50 Mbps of bandwidth, you should use backup copy jobs with WAN acceleration enabled. This will reduce the amount of data that needs to be transferred over the network and speed up the backup process12. The simplest configuration would be an immediate copy mode with WAN acceleration 

from https://helpcenter.veeam.com/docs/backup/agents/integration_instant_restore_vsphere.html?ver=120 "Restore to vSphere VM The procedure of Instant Recovery for a Veeam Agent computer practically does not differ from the same procedure for a VM. The main difference from Instant Recovery is that you do not need to select the recovery mode, because Veeam Agent computers are always restored to a new location."

According to the Veeam Backup & Replication user guide1, you can use the Guest File Restore wizard to restore files and folders from VM guest OSes that run Linux or other non-Windows OSes2. The wizard allows you to choose how to handle situations when restored files already exist on the target location3.

Therefore, if you want to restore the folder of traffic photos to their original location and do not want to lose the original files, you should use the Keep function. This function will preserve original files on disk and will not overwrite them with restored files

According to the Veeam Backup & Replication User Guide1, you can change the backup copy mode by editing backup copy job settings. However, this is only possible if the backup copy job has true per-machine backup storage format.

To properly back up Microsoft Exchange databases in an environment using Veeam Agent for Microsoft Windows, you would need to configure "Exchange Processing." This option allows Veeam to interact with the Exchange server, ensuring that it quiesces the databases and transaction logs correctly to create consistent backups of the Exchange data. This is essential for the proper backup and recovery of Exchange databases, especially in environments with Database Availability Groups (DAGs) where data consistency is critical.

It is recommended that you use quick rollback if you restore a VM or VM disk after a problem that has occurred at the level of the VM guest OS — for example, there has been an application error or a user has accidentally deleted a file on the VM guest OS "Windows update installation is a OS Problem"

According to the Veeam Backup & Replication user guide1, you can use the File Level Restore wizard to restore files and folders from VM guest OSes that run Windows2. The wizard allows you to choose how to access the VM guest OS: through network or through VIX2VIX is a VMware API that enables programmatic access to virtual machine operations3.

Therefore, if you want to restore a file on a Windows VM hosted on vSphere and the mount server cannot connect to the VM through the network, you can use VIX as an alternative method of access2. This will allow you to restore the file directly to its original location without downloading it locally or starting an Instant VM Recovery session.

The "Move to capacity tier" option allows you to move older backups to a lower-cost storage tier (such as object storage) while keeping recent backups on faster, on-premises storage. This helps optimize storage usage on the primary repository and ensures that backups are stored offsite for long-term retention.

"Failover Now: Failover now refers to an immediate response to an unexpected system or service failure. In this case, the primary system or service experiences an unplanned outage or becomes unavailable, and the failover process is triggered immediately to shift the workload to a secondary system or service."

https://helpcenter.veeam.com/archive/backup/110/vsphere/failover_plan_undo.html

According to the Veeam Backup & Replication user guide1, a failover plan is a set of rules that defines how VMs must be failed over to their replicas1. You can create and run failover plans for regular replicas and CDP replicas1.

After you run a failover plan, you can perform the following actions on it2:

• Undo — reverts VMs in the failover plan back to their original state at the production site2.
• Start — runs the failover plan again if you need to repeat the failover operation for some reason2.
• Edit — modifies the settings of the failover plan, such as adding or removing VMs, changing their order or time delay1.
• Delete — removes the failover plan from Veeam Backup & Replication. This does not affect the VM replicas that are used by the plan1.

By performing a restore of only the VM configuration files, you can quickly recreate the VM in VMware vSphere using the existing disk files on the datastore. This method avoids the need to transfer or copy large VM disk files, resulting in a faster restoration process. Note that this method assumes that the VM disk files are still intact on the datastore. If any of the VM disk files are missing or corrupted, you may need to consider alternative restoration methods or perform a full restore from the Veeam backup files.

According to the Veeam Agent for Linux User Guide1, Veeam Agent for Linux lets you use the Veeam Recovery Media — a recovery image of the Linux OS that provides an alternative way to boot your computer. The recovery image is an ISO file that you can burn to a CD/DVD or write to a USB flash drive.

According to the Veeam Backup & Replication user guide1, you can use a long-term retention policy (GFS) to keep backup files for longer periods of time. GFS stands for grandfather-father-son and refers to a backup rotation scheme that allows you to create weekly, monthly, quarterly and yearly restore points12.

Therefore, if you want to be able to restore the VMs to any given day within two months and any given week within six months, you should use a GFS policy with 62 days of retention and 26 weekly GFS restore points. The simplest configuration would be an immediate copy (mirroring) mode with these settings (option B).

When performing a file-level restore, you need to specify a host on which the restored file system will be mounted. This host can be a separate machine or the same machine where Veeam Backup & Replication is installed. The restored files from the backup image will be mounted on this host, allowing you to browse and extract the specific files or directories you need.
