Question 1
It has been determined that the onsite repositories need to be immutable. How should the repositories be configured to easily allow for additional capacity to be added?
Stand-alone repositories using NTFS.
Scale-out Backup Repositories consisting of hardened ReFS repositories.
Stand-alone repositories using the XFS file system.
Scale-out Backup Repositories consisting of hardened repositories.
Explanation:
The repositories should be configured as Scale-out Backup Repositories consisting of hardened repositories to easily allow for additional capacity to be added and to meet the immutability requirement.Scale-out Backup Repository is a logical entity that groups several backup repositories into a single pool of storage, and allows to add or remove backup repositories as needed1.Hardened repository is a Linux-based backup repository with immutability enabled, which prevents backup files from being modified or deleted until the specified retention period expires2.The other options are either not immutable (option A and C, as NTFS and XFS do not support immutability) or not scalable (option B, as ReFS does not support adding or removing extents in a Scale-out Backup Repository3).Reference:Scale-out Backup Repository,Hardened Repository,ReFS Limitations.
Question 2
It has been determined that the onsite repositories need to be immutable. Which configuration would ensure SLA compliance and provide protection against ransomware?
Provide a Veeam Backup & Replication server with Veeam replication and enable XFS with immutability on NFS targets.
Leverage hardened repositories at both primary and secondary sites, and offload to object storage in a public cloud with immutability enabled.
Leverage ReFS repositories as a primary target with a backup copy to a second site and offload to object storage in a public cloud with immutability enabled.
Provide Veeam Backup & Replication servers at two locations and leverage object storage.
Explanation:
Immutable repositories are backup storage locations that prevent unauthorized modifications or deletions of backup data, ensuring its integrity and recoverability.Immutable repositories are essential for protecting backups against ransomware attacks, accidental deletions, or malicious insiders1.
Veeam Backup & Replication supports several types of immutable repositories, such as hardened repositories, immutable object storage repositories, and immutable deduplicating storage appliances2. Among these options, the best configuration for ensuring SLA compliance and providing protection against ransomware is to leverage hardened repositories at both primary and secondary sites, and offload to object storage in a public cloud with immutability enabled.
Hardened repositories are Linux-based repositories that use XFS file system with immutability flag to protect backup files from changes or removals.Hardened repositories can be used as primary or secondary backup targets, and can be combined with Veeam Scale-out Backup Repository to simplify backup management and optimize storage utilization3.
Object storage repositories are cloud-based repositories that use object storage services, such as Amazon S3, Microsoft Azure Blob Storage, or Google Cloud Storage, to store backup data. Object storage repositories can be used as secondary backup targets, and can leverage the immutability feature of the cloud provider to prevent backup data from being overwritten or deleted.
By using hardened repositories at both primary and secondary sites, you can achieve high availability and redundancy for your backup data, as well as fast and reliable restores. By offloading to object storage in a public cloud with immutability enabled, you can achieve long-term retention and compliance, as well as cost savings and scalability. This configuration also follows the 3-2-1-1 backup rule, which recommends having three copies of data, on two different types of media, with one copy off-site and one copy immutable.
You can find more information about immutable repositories and how to configure them in the following resources:

Question 3
examining the list of requirements, you notice that it is necessary to have backups encrypted. If you use Veeam's native encryption, which repository type will be the most impacted?
Dedupe repositories
Immutable Linux Repository with XFS reflink cloning
NFS share repository
Windows ReFS with block cloning
Explanation:
The repository type that will be most impacted by using Veeam's native encryption is dedupe repositories. Dedupe repositories are backup repositories that use deduplication appliances or software to reduce backup size and optimize storage utilization. However, if you use Veeam's native encryption for backup jobs that target dedupe repositories, you will lose most of the deduplication benefits, as encrypted data blocks cannot be deduplicated effectively. Therefore, it is recommended to use either the encryption feature of the deduplication device or software, or avoid encryption altogether for dedupe repositories.
Question 4
Which type of backup job will you need more informacion on to properly plan backup copy job settings later to make sure you are creating the required number of restore point per day offsite?
Bronze tier backup jobs
Silver tier backup jobs
Gold tier backup jobs
Laptop backup jobs
Explanation:
The gold tier backup jobs have the most stringent recovery point objective (RPO) of one hour for image backup and 15 minutes for transaction log backup. This means that they need to run more frequently than the other backup jobs and create more restore points per day. Therefore, to properly plan the backup copy job settings, you will need more information on the gold tier backup jobs, such as the number of VMs, the size of backups, the change rate, the retention policy, and the bandwidth available for copying backups to the offsite location.
Question 5
What information related to the virtual infrastructure is missing and must be collected during the discovery phase) (Choose 2)
Number of vSphere clusters
Backup window
Recovery time objective
Total of virtual machines
Number of scale-out Backup Repository extents currently used
Explanation:
The number of vSphere clusters and the total of virtual machines are important information related to the virtual infrastructure that are missing and must be collected during the discovery phase. These information can help you estimate the backup performance, scalability, and resource requirements for the Veeam backup infrastructure. For example, you can use the number of vSphere clusters to determine how many Veeam backup servers and proxies you need to deploy and how to distribute the backup load among them. You can also use the total of virtual machines to calculate the total amount of data to be backed up, the storage space required, and the network bandwidth needed.
Question 6
While going through the discovery data for the NAS environment, you determine several key metrics are missing for later deign and sizing. Which of the following should you collect from the customer about the data stored on the on the NAS per site? (Choose 3)
Retention requirements
Total number of files (in millions) to be backed up
Amount of source data before dedupe and compression
Number of shares and compressed source data
Large file size
Question 7
The company has committed to providing the numbers for source in-use data for gold tier virtual machines. In order to attempt to collect metrics for hourly gold tier backups, which of the following additional metrics are need for proxy sizing?
Yearly growth rate
Change rate
Datastore type
Operating system type
Question 8
You are examining the requirement: ''If possible, the data written must be unchangeable to prevent ransomware attacks.'' Which types of jobs do not support using immutability from S3 Object Lock or hardened repositories? (Choose two)
NAS backups
Linux Agent backup copy jobs
VMware backup jobs
Agent for Mac backups
Explanation:
The types of jobs that do not support using immutability from S3 Object Lock or hardened repositories are NAS backups and Agent for Mac backups. These types of jobs do not have the option to enable immutability in their settings, unlike VMware, Hyper-V, Linux Agent, or Windows Agent backup jobs. Therefore, they cannot leverage the immutability feature of S3 Object Lock or hardened repositories to protect their backups from ransomware or malicious deletion.
Question 9
The customer has stated that they plan on purchasing new physical server component and repository storage. What additional information is needed to define the implementation process later?
Will the customer need to unencrypt the backups before being copied to new storage?
How much backup data is stored on the old hardware?
Will the customer be able to retain the original storage until the existing restore points expire?
Is the customer repurposing old hardware?
Explanation:
The additional information that is needed to define the implementation process later is how much backup data is stored on the old hardware. This information is important for designing and sizing the migration strategy and timeline for moving the backups from the old hardware to the new hardware. For example, you can use the amount of backup data to estimate how long it will take to copy or move the backups to the new storage devices. You can also use the amount of backup data to determine whether you need to use compression, deduplication, or WAN acceleration to optimize the migration traffic.
Question 10
What components can help meet the following requirement: ''Alternative decryption capabilities on encrypted backups must be possible in the event of lost passwords''?
Veeam Backup & Replication's Configuration Backups
Veeam Backup Enterprise Manager
Veeam Backup & Replication's Extraction Explorer
Veeam Backup & Replication's Extract Utility
Explanation:
The component that can help meet the requirement of alternative decryption capabilities on encrypted backups in the event of lost passwords is Veeam Backup Enterprise Manager. Veeam Backup Enterprise Manager is a web-based interface that allows centralized management of multiple Veeam backup servers. It also provides a password loss protection feature that enables authorized users to restore encrypted backups without entering passwords if they forget or lose them. This feature requires enabling password loss protection in Veeam Backup Enterprise Manager settings and assigning a security officer role to a user who can approve password recovery requests.
