VEEAM VMCA2022 Exam Questions

Thank you for your question. I'm glad to help you with your VMCA 2022 project.

To design a solution that meets the needs and requirements of Veeam University Hospital, you need to consider the impact and benefit of adding extra proxy servers to your backup infrastructure. This will help you to optimize the performance and efficiency of your backup and restore operations, as well as to prepare for future growth and expansion.

According to the web search results, a proxy server is a component that retrieves data from the source host, processes it and transfers to the backup repository. It also performs data compression, deduplication, encryption, etc. You can deploy backup proxies both in the primary site and in remote sites1.

The immediate result of adding the extra proxy server is A. The time for backup to complete could be reduced.

This result means that:

* The time for backup to complete is a metric that measures how long it takes to perform a backup job from start to finish. It depends on various factors, such as the size and type of data, the backup method and frequency, the network bandwidth and latency, etc.

* Adding an extra proxy server can reduce the time for backup to complete, by distributing the backup workload between available proxy servers. This can improve the backup performance and efficiency, as well as reduce the impact on the production environment.

* Reducing the time for backup to complete can also help you to meet your backup window and recovery point objective (RPO) requirements, as well as to free up more resources for other tasks or jobs.

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).Reference:Veeam Certified Architect 2022 Exam Guide, page 10;Veeam Backup & Replication v11: Architecture and Design course, module 3.

If using Veeam's native encryption, the repository type that will be impacted the most is the deduplicating storage appliance. This is because Veeam Backup & Replication uses different encryption keys for every job session, which makes the encrypted data blocks appear as different even if they contain duplicate data. This reduces the deduplication ratio and increases the storage consumption on the deduplicating appliance. If you want to achieve a higher deduplication ratio, you can disable data encryption or use the encryption feature on the deduplicating appliance itself1

The things that can be done to validate that the design meets target SLAs and reduces the headcount required to manage the solution are:

Use tagging and scripts to auto-generate backup jobs, set the start time and windows, letting the backup server manage resource allocation.This option allows to automate the backup job creation and configuration, based on the tags assigned to the source objects, such as VMs, hosts, or clusters1.This reduces the manual effort and human error involved in managing the backup jobs, and ensures that the backup server allocates the optimal resources for each job, based on the load balancing and performance settings2.

Explain how to detect configuration changes, reporting and using backup job templates to maintain consistency. Document self-service restore the streamline service desk engagement.This option allows to monitor the backup infrastructure and detect any changes that may affect the backup performance or reliability, such as adding or removing VMs, hosts, or clusters3.It also allows to use backup job templates to create consistent and standardized backup policies, and apply them to multiple backup jobs4.Additionally, it allows to document the self-service restore process, which enables end-users to perform file-level restores from their own backups, without involving the backup administrator or the service desk5.

Review the design so that the slowest part of the infrastructure is fast enough to meet backup window requirements. This option allows to identify and optimize the bottleneck in the backup infrastructure, which is the component that limits the backup speed and throughput. By reviewing the design and ensuring that the slowest part of the infrastructure can meet the backup window requirements, the backup SLAs can be achieved and the backup performance can be improved.

The other options are either not relevant for validating the design (option A and E, as exporting the configuration, scheduling a review, and reviewing the design for bottlenecks are part of the design process, not the validation process) or not effective for meeting the SLAs and reducing the headcount (option C, as using inventory information, backup chaining, and fine tuning are manual and complex tasks that may not guarantee the backup window compliance or resource efficiency).Reference:Tagging,Load Balancing and Performance,Configuration Change Tracking,Backup Job Templates,Self-Service File Restore, [Bottleneck Statistics]

Network traffic rules are settings that allow you to control the network traffic transferred between backup infrastructure components, such as backup proxies, repositories, and WAN accelerators.You can use network traffic rules to throttle or encrypt the network traffic, or to specify preferred networks for data transfer1.

By configuring network traffic rules, you can reduce the bandwidth consumption for the offloading of data to public cloud storage, and avoid affecting the performance of business applications on the branch sites.You can set limits for the network traffic speed, or schedule the offloading tasks to run during off-peak hours2.You can also select the optimal network routes for the offloading tasks, and avoid congested or slow networks3.
