Answer : A

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.

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]

Answer : A

Backup from storage snapshot is a feature of Veeam Backup & Replication that leverages the native snapshot capabilities of the storage system to create a consistent point-in-time copy of the VM data.Veeam Backup & Replication then reads data directly from the storage snapshot, bypassing the ESXi host and reducing the impact on the production environment1.Backup from storage snapshot is supported for VSAN datastores on NetApp, Nimble, Dell EMC, HPE, and Pure Storage systems2.

Using backup from storage snapshot for the virtualized stock trading application servers can improve the backup performance and reduce the latency, as it minimizes the time that the VM is running on a snapshot and avoids the network overhead of other transport modes3.

The other options are not recommended because:

B) Implementing Veeam Agent on the virtualized stock trading application servers is not necessary, as Veeam Backup & Replication can protect VMware VMs without agents.Veeam Agent is mainly used for physical servers, workstations, or cloud instances4.

C) Using Veeam Replication to create replicas of the virtualized stock trading application servers at the remote site, then back up the replicas is not optimal, as it adds more complexity and cost to the backup process.Veeam Replication is mainly used for disaster recovery purposes, not for backup5.

D) Turning off application-aware processing for the virtualized stock trading application servers is not advisable, as it may compromise the consistency and recoverability of the application data. Application-aware processing is a feature of Veeam Backup & Replication that ensures that the application data is in a consistent state before the backup or replication job starts.

Answer : D

The best way to deploy the proxies for the remote office is to deploy eight virtual proxies with eight CPUs and 16 GB of RAM each.This option allows to leverage the Virtual appliance (Hot-Add) mode, which is the recommended transport mode for VSAN storage1.Virtual appliance mode enables LAN-free data transfer between the source datastore and the proxy, as well as load balancing and fault tolerance across multiple proxies2.The other options are either not optimal (option A and B, as physical proxies require LAN or SAN connection to access the source data, which may impact the network performance and backup SLAs3) or not supported (option C, as virtual proxies with more than eight CPUs are not compatible with Virtual appliance mode).Reference:Transport Modes,Virtual Appliance Mode,Direct Storage Access Mode, [Requirements and Limitations for VMware Backup Proxies].

Answer : A, E

Backup from Storage Snapshots and Direct NFS are the preferred processing modes for NFS datastores, as they offer the best performance and reliability for backup and restore operations12.

Backup from Storage Snapshots is a feature of Veeam Backup & Replication that leverages the native snapshot capabilities of the storage system to create a consistent point-in-time copy of the VM data.Veeam Backup & Replication then reads data directly from the storage snapshot, bypassing the ESXi host and reducing the impact on the production environment3.Backup from Storage Snapshots is supported for NFS datastores on NetApp, Nimble, Dell EMC, HPE, and Pure Storage systems4.

Direct NFS is a proprietary transport mode of Veeam Backup & Replication that uses a native NFS client deployed on the backup proxy to read and write data directly from and to the NFS datastore. Veeam Backup & Replication also bypasses the ESXi host and reduces the load on the production environment. Direct NFS is supported for NFS datastores on any storage system that supports NFS version 3 or 4.1.

The other options are not preferred because:

B) Network (NBD) mode is a transport mode that uses the VMware VDDK to communicate with the ESXi host over the network. This mode produces additional load on the ESXi host and the network, and may result in slower backup and restore performance.

C) Virtual Appliance (HotAdd) mode is a transport mode that uses the VMware VDDK to attach the disks of the processed VM to the backup proxy VM. This mode also produces additional load on the ESXi host and the network, and may cause issues with disk alignment or SCSI controller limitations.

D) Network mode with Encryption (NBDSSL) mode is a transport mode that uses the VMware VDDK to communicate with the ESXi host over the network with SSL encryption. This mode provides an extra layer of security, but also adds more overhead and reduces the backup and restore performance.

Answer : A

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.

Answer : A

To design a solution that meets the requirements for off-site immutable backups for Veeam University Hospital, you need to consider some of the options and features that Veeam products and features offer. This will help you to ensure the security and integrity of your backup data, as well as the compatibility and supportability of the cloud provider that does not currently support immutability.

According to the Veeam Backup & Replication Best Practice Guide, immutability is a feature that prevents backup files from being deleted or modified by anyone until the specified retention period expires. Immutability can be achieved by using S3 Object Lock or Hardened Repository, which are two different solutions that Veeam Backup & Replication supports.

Based on this definition, the best option to still satisfy the requirements for off-site immutable backups is A. Backup copy to a hardened repository.

This option means that:

* The backup copy is a type of job that allows you to create and maintain copies of your backup data on a secondary backup repository. You can use backup copy jobs to send your backup data off-site, as well as to apply different retention settings and policies.

* The hardened repository is a solution that allows you to add a hardened repository based on a Linux server to your backup infrastructure. You can use hardened repository with Veeam Backup & Replication to make your backups immutable on-premises or off-site.

* The backup copy to a hardened repository can be configured and managed by Veeam Backup & Replication, regardless of the cloud provider that does not currently support immutability. You only need to deploy and connect a Linux server with a hardened repository in the cloud environment, and then use it as a target for your backup copy jobs.
