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.

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 : D

The additional condition of the offsite backup that is presumed by the immutability requirement is that a copy of backup data must reside in a public cloud local to each region.Immutability means that the backup data cannot be modified, deleted, or overwritten by anyone, including the backup administrator, the cloud provider, or malicious actors1.Veeam Backup & Replication v11 supports immutability for backups stored in Amazon S3 and Microsoft Azure Blob Storage, using the Object Lock feature2. Therefore, the offsite backup must use one of these cloud providers, and must be located in the same region as the source data, to comply with the data locality and privacy laws. The other options are not related to the immutability requirement, as they are either already stated in the business requirements (option A), technical requirements (option B), or not relevant for the Veeam solution (option C).Reference:Immutability,Object Storage Immutability.

Answer : A

According to the Veeam Backup & Replication Best Practice Guide1, the proxy and repository servers are the components that should be sized correctly to ensure that synthetic operations and backup copy jobs can be completed in the desired window. This is because:

* The proxy server is responsible for retrieving data from the source and sending it to the target. The proxy server performance depends on the CPU, memory, network, and storage resources available. The proxy server should have enough CPU cores and memory to handle concurrent tasks, as well as sufficient network bandwidth and storage throughput to transfer data efficiently.

* The repository server is responsible for storing backup files on the target storage. The repository server performance depends on the CPU, memory, network, and storage resources available. The repository server should have enough CPU cores and memory to handle concurrent tasks, as well as sufficient network bandwidth and storage throughput to write data efficiently. The repository server should also support the backup format and retention policy chosen for the backup copy job.

Answer : D

Based on the customer Windows and Linux file server backup requirements, the best component to help them meet their stated objectives is Backup Enterprise Manager with indexing enabled on virtual machine and Agent backups with RBAC policies. This is because:

* Backup Enterprise Manager allows the customer to manage and monitor backup jobs across multiple backup servers from a single web-based interface1.

* Indexing enables the customer to perform file-level recovery from the backups of Windows and Linux servers, as well as search for files across all backups2.

* RBAC policies allow the customer to delegate permissions to different users and groups for performing file-level recovery, based on their roles and restore scopes3.
