During further discussions, the 3-2-1 rule was recommended. What is the most efficient way to protect primary and secondary sites following the 3-2-1 rule?
- A. Send backups directly from the primary to the secondary site, avoiding duplicate data storage. Tier backup data to object storage using Scale-out Backup Repository capacity tier.
- B. From existing backups at the primary site, create a backup copy to the secondary site. Offload backup data to object storage using Scale-out Backup Repository capacity tier.
- C. Use storage snapshot support to backup a virtual machine using the secondary array. Backup snapshots on the secondary site and tier this to object storage using Scale-out Backup Repository capacity tier.
- D. Send replicas directly from the primary to the secondary site. Backup replicas on the secondary site and tier this to object storage using Scale-out Backup Repository capacity tier.
正解：B
解説：
Explanation
Option A follows the 3-2-1 rule by having three copies of data (the original production data, the backup at the primary site, and the backup copy at the secondary site), two different media types (local disk and object storage), and one copy off-site (the backup copy at the secondary site). This option also reduces the amount of traffic sent over the network by using existing backups as seeds for backup copies, and reduces the storage costs by using cloud tier to move older backups to cheaper and unlimited cloud storage1 Reference: What is the 3-2-1 backup rule? - Veeam
質問 # 44
Immutability of the offsite backups is a constraint on this project. Which of the following requirements does this impact?
- A. All data must be retained for three years.
- B. Backups must be verified and scanned for malware before restoring.
- C. Backup must take advantage of public cloud storage for long-term retention.
- D. Backup must be storage in logical, scalable storage systems on site.
正解：C
解説：
Explanation
To design a solution that meets the immutability requirement for Veeam University Hospital, you need to consider how this constraint affects the other requirements and expectations of the customer. This will help you to avoid any conflicts or inconsistencies that may arise from applying immutability settings to the backup data.
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 periodexpires.
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 requirement that is impacted by the immutability constraint is D. Backup must take advantage of public cloud storage for long-term retention.
This requirement is impacted by the immutability constraint because:
*Public cloud storage is a type of storage that is provided by a third-party service provider over the internet, such as Amazon S3, Microsoft Azure, Google Cloud, etc.
*Public cloud storage can be used for long-term retention, which is a policy that defines how long backup data should be kept for compliance or historical purposes, such as months, years, or decades.
*Public cloud storage can also support immutability, which is a feature that prevents backup data from being deleted or modified by anyone until the specified retention period expires, such as days, weeks, or months.
*However, not all public cloud storage providers or services support immutability, or support it in the same way. For example, Amazon S3 supports S3 Object Lock, which allows you to apply a legal hold or a retention period to individual objects or object versions. Microsoft Azure supports Immutable Blob Storage, which allows you to create time-based policies or legal holds for blob containers. Google Cloud supports Bucket Lock, which allows you to lock a bucket and prevent objects from being overwritten or deleted.
*Therefore, the choice of the public cloud storage provider or service may affect the immutability setting and requirement for the backup data. You need to verify and compare the compatibility and supportability of the public cloud storage providers or services with Veeam Backup & Replication and with the customer expectation.

What information related to the virtual infrastructure is missing and must be collected during the discovery phase) (Choose 2)
- A. Recovery time objective
- B. Number of vSphere clusters
- C. Backup window
- D. Number of scale-out Backup Repository extents currently used
- E. Total of virtual machines
正解：B、E
解説：
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.

質問 # 46
Assuming that you put the backup repositories in the backup network only, what possible issue could arise?
- A. Laptop agents cannot communicate with the repository.
- B. SQL logs cannot be shipped to repository.
- C. Capacity Tier Could offload is no possible.
- D. The proxies cannot communicate with the repositories.
正解：A
解説：
Explanation
A possible issue that could arise if you put the backup repositories in the backup network only is that laptop agents cannot communicate with the repository. This is because laptop agents are not part of the backup network, which is non-routable according to the existing technical environment.Therefore, laptop agents cannot access or write data to the backup repositories in the backup network unless there is a proxy or gateway server that can bridge the communication between them.

質問 # 47
Veeam University Hospital has been testing the potential to keep their existing NFS storage at each site:
however, they have encountered poor backup throughput performance between sites. What would be an effective way to improve the performance?
- A. Have a mount server at each location.
- B. Ensure you use location tags at the target location.
- C. Ensure the Gateway Server is located close to the NFS backup storage.
- D. Place the backup proxy and Gateway Server together at the source site.
正解：D
解説：
Explanation
The Gateway Server is a component that acts as a data mover between the backup proxy and the NFS storage.
By placing the backup proxy and the Gateway Server together at the source site, you can reduce the network traffic and latency between them, and improve the data transfer speed. The Gateway Server will read data from the NFS storage and send it to the backup proxy over a local connection, and the backup proxy will process and compress the data before sending it to the target site1
質問 # 48
Veeam University Hospital perform a proof of concept of the design outline in the architecture. Backups completed successfully, but it is determined that backup copy jobs between sites are not completing in the required timeframe. During the result analysis, it was discovered that the bandwidth between sites was heavily saturated. What adjustments within the Veeam infrastructure would best address this issue?
- A. Add WAN accelerators to each site.
- B. Increase the proxy computer resources at each site.
- C. Have the customer implement Quality of Service on their WAN connections.
- D. Increase the computer resources on the repository servers at each site.
正解：A
解説：
Explanation
WAN accelerators are dedicated components that Veeam Backup & Replication uses for WAN acceleration.
WAN accelerators are responsible for global data caching and data deduplication, which reduce the amount of data that needs to be transferred over the network. By adding WAN accelerators to each site, you can improve the performance of backup copy jobs between sites, and reduce the bandwidth consumption and network traffic3 References:

- A. The size of the Veeam Backup & Replication database will double.
- B. The time for backup to complete could be reduced.
- C. Extra repository servers will be needed.
- D. Repository capacity will decrease.
正解：B
解説：
Explanation
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.

質問 # 52
Based on the customer's hardening requirements, what steps should be taken to correct the storage configuration?
- A. Create new Scale-out Backup Repositories with ReFS and redirect backups to new Scale-out Backup Repositories.
- B. Send backup copy jobs directly to object storage
- C. Enable the object lock on the CIFS extents
- D. Add hardened repositories to each Scale-out Backup Repository and evacuate the data from the CIFS extents.
正解：D
解説：
Explanation
The steps that should be taken to correct the storage configuration based on the customer's hardening requirements are to add hardened repositories to each Scale-out Backup Repository and evacuate the data from the CIFS extents. A hardened repository is a type of backup repository that provides immutability and ransomware protection for backup files by using Linux XFS file system features and Linux access control mechanisms. A Scale-out Backup Repository is a logical entity that groups several backup repositories into one pool of storage. A CIFS extent is a type of backup repository that uses a shared folder on a Windows or Linux server as a backup target. By adding hardened repositories to each Scale-out Backup Repository, you can ensure that your backups are secure, compliant, and efficient. By evacuating the data from the CIFS extents, you can remove the risk of ransomware infection or deletion of your backups.
質問 # 53
Based on additional discovery, it was determined that a few critical workloads need to maintain a less than five-minute recovery point objective. Which of the following would be the recommended method to replicate VMware virtual machines?
- A. Veeam Continuous Data Protection.
- B. Veeam Image-based replication
- C. Veeam backup copy with immediate mode
- D. Custom PowerShell scripting.
正解：A
解説：
Explanation
The recommended method to replicate VMware virtual machines with a less than five-minute RPO is Veeam Continuous Data Protection (CDP). CDP is a feature that allows near-continuous replication of VMware virtual machines to a secondary site or cluster with minimal data loss and downtime. CDP uses VMware vSphere APIs for I/O Filtering (VAIO) to capture every write operation from the source VMs and send them to the target VMs in near real-time. CDP can achieve RPOs as low as seconds and enable fast failover and failback in case of a disaster.

- A. Amount of source data before dedupe and compression.
- B. Total number of files (in millions) to be backed up.
- C. Largest file size.
- D. Amount of source data after dedupe and compression.
- E. Which version of SMB protocol the NAS supports.
正解：B、C
解説：
Explanation
To design a solution that meets the NAS environment requirements for Veeam University Hospital, you need to collect some information during the discovery phase. This information will help you to understand the characteristics and performance of the NAS systems, the size and type of the data, and the backup and recovery objectives.
According to the Veeam Backup & Replication Best Practice Guide, some of the information that you should collect from the customer about the data stored on the NAS per site are:
*Total number of files (in millions) to be backed up. This information will help you to estimate the backup storage requirements, as well as the backup performance and scalability, based on the number and distribution of files.
*Largest file size. This information will help you to determine the optimal backup block size and alignment, as well as the backup compression and deduplication ratios, based on the size and type of files.
質問 # 55
While deciding which transport mode to use for the proxies, you notice that one of the requirements is support the encrypted datastore in VMware. Which processing modes can you leverage for the backup proxies?
(Choose 3)
- A. Direct NFS.
- B. Virtual Appliance (HotAdd) mode.
- C. Network (NBD) mode.
- D. Direct SMB.
- E. Direct SAN.
- F. Network mode with Encryption (NBDSSL).
正解：B、D、F
解説：
Explanation
To access encrypted datastores in VMware, you need to use a transport mode that supports encryption. The following transport modes support encryption:
*Network mode with Encryption (NBDSSL): This mode uses an encrypted network connection between the backup proxy and the ESXi host to read and write data from the encrypted datastore. This mode does not require direct access to the datastore, but it can be slower than other modes due to network traffic and encryption overhead2
*Virtual Appliance (HotAdd) mode: This mode uses a virtual backup proxy that runs on an ESXi host and attaches virtual disks of the encrypted VMs to itself using the VMware vSphere API. This mode requires that the backup proxy and the source VMs reside on the same datastore or on datastores that are accessible by the same ESXi host. This mode can offer better performance than network mode, but it can also cause SCSI reservation conflicts if multiple backup proxies access the same datastore simultaneously3
*Direct SMB: This mode uses a physical backup proxy that accesses the encrypted datastore over the SMB protocol. This mode requires that the datastore is configured as an SMB share and that the backup proxy has read and write permissions on it. This mode can offer high performance and scalability, but it also requires additional configuration steps and security considerations4 The following transport modes do not support encryption:
*Network (NBD) mode: This mode uses an unencrypted network connection between the backup proxy and the ESXi host, which cannot access encrypted datastores2
*Direct SAN: This mode uses a physical backup proxy that accesses the encrypted datastore over the SAN fabric, which cannot decrypt encrypted data5
*Direct NFS: This mode uses a physical backup proxy that accesses the encrypted datastore over the NFS protocol, which does not support encryption6 References:

質問 # 56
During architecture planning, Veeam Life and Indemnity decides that recovery point objective of gold tier machines should change from one hour to three hours with daily retention set to seven days. What will be impact on the Veeam design?
- A. The Veeam database size will increase.
- B. More proxy servers will be required
- C. Proxies will require fewer resources
- D. Repositories will require more resources.
正解：C
解説：
Explanation
If the recovery point objective (RPO) of gold tier machines changes from one hour to three hours with daily retention set to seven days, the impact on the Veeam design is that proxies will require fewer resources. This is because the backup frequency and the number of restore points for gold tier machines will decrease, which means that less data will need to be processed and transferred by the proxies. Therefore, the proxies will have lower CPU, memory, disk, and network utilization and can handle more backup tasks with the same resources.
質問 # 57
What information related to sizing the NAS infrastructure is missing and must be collected during the discovery? (Choose 2)
- A. Total number of network shares
- B. Recovery point objective
- C. Size of the source data set
- D. Number of Scale-out Backup Repository extents currently used
- E. Backup windows
正解：B、C
解説：
Explanation
The information related to sizing the NAS infrastructure that is missing and must be collected during the discovery are the size of the source data set and the recovery point objective (RPO). These information are important for designing and sizing the NAS backup jobs and repositories. For example, you can use the size of the source data set to estimate how much storage space and network bandwidth are required for backing up NAS devices. You can also use the RPO to determine how frequently you need to run NAS backup jobs and how many restore points you need to keep on the backup repositories.

質問 # 60
Which of the following could cause failures to meet the requirement to test gold tier backups?
- A. You cannot firewall traffic between vLANs in the SureBackup job configuration.
- B. There may be too many networks.
- C. Backup jobs run every hour.
- D. The LAN bandwidth is not sufficient for vPower NFS datastores.
正解：A
解説：
Explanation
A possible cause of failures to meet the requirement to test gold tier backups is that you cannot firewall traffic between vLANs in the SureBackup job configuration. This could prevent the gold tier virtual machines from communicating with each other or with other required services in the isolated virtual lab. For example, if a gold tier virtual machine needs to access a database server or a domain controller in another vLAN, it might fail to start or function properly in the SureBackup job. Therefore, it is important to ensure that all necessary vLANs and network settings are configured correctly in the SureBackup job.

- A. Configure Veeam ONE to send SNMP traps to the ticketing system.
- B. Veeam Backup & Replication integrates directly with Service Now and Remedy ticketing software natively.
- C. Integrate Veeam ONE with the ticketing software using plug-in in the supplemental folder on the Veeam ISO.
- D. Configure Veeam Backup & Replication to send email notification to the helpdesk email account and have someone generate the ticket manually.
正解：A
解説：
Explanation
Veeam University Hospital is considering using Veeam ONE to collect alarms from the virtual and backup infrastructure. Veeam ONE is a powerful monitoring and reporting tool that provides visibility and insight into the performance, configuration, and utilization of your backup and virtual infrastructure. Veeam ONE can also alert you about any issues or problems that may affect the availability or reliability of your data protection and recovery processes.
One of the options that is available for integrating Veeam ONE with ticketing systems is A. Configure Veeam ONE to send SNMP traps to the ticketing system.
This option means that:
*SNMP (Simple Network Management Protocol) is a protocol that allows network devices to communicate and exchange information with each other.
*SNMP traps are messages that are sent by network devices to notify a management system about events or conditions that require attention or action.
*Veeam ONE can be configured to send SNMP traps to a ticketing system when an alarm is triggered or resolved. This allows you to automate the creation and update of tickets based on the alarm data, such as the alarm name, severity, status, description, etc.
*To configure Veeam ONE to send SNMP traps to a ticketing system, you need to enable SNMP notifications in the Veeam ONE settings, as well as specify the SNMP server address, port, community string, and trap format. You also need to configure the ticketing system to receive and process the SNMP traps from Veeam ONE.
This option is a good choice for integrating Veeam ONE with ticketing systems, as it allows you to leverage the benefits and features of both solutions, such as:
*You can use Veeam ONE to monitor and analyze your backup and virtual infrastructure, as well as to detect and alert you about any issues or problems that may affect your data protection and recovery processes.
*You can use the ticketing system to manage and track the resolution of the issues or problems that are reported by Veeam ONE, as well as to assign and prioritize tickets to the appropriate staff or team members.
質問 # 62
Based on Customer requirements, how should virtual machine backups be scoped? (Choose 2)
- A. Create backups based on protection groups create with a CSV file.
- B. Create backups based on resource pools
- C. Create backups based on tags.
- D. Scope each backup based the software running in each workload
- E. Create backups jobs with same retention requirements.
正解：C、E
解説：
Explanation
The methods that should be used to scope virtual machine backups based on customer requirements are to create backups based on tags and to create backup jobs with same retention requirements. Creating backups based on tags allows dynamic scoping of backups based on VMware tags assignedto virtual machines. This can simplify backup management, as new or modified virtual machines will be automatically included or excluded from backup jobs based on their tags. Creating backup jobs with same retention requirements allows consistent application of backup policies based on the backup tiers defined by the customer. This can ensure compliance with regulatory and business needs, as different tiers of virtual machines will have different retention periods and restore points.
質問 # 63
Upon further discussions with the database administrador, it was discovered that they would preferent their transaction log backups to exist alongside their image-level SQL application aware backups residing on object storage. How can this be accomplished?

- B. Using SQL native tools, send logs to a dedicated virtual machine, protect with image-level backups, using Scale-out Backup Repository capacity tier for offload.
- C. Using SQL native tools, send logs to dedicated virtual machine, schedule a task calling a cloud vendor object storage CLI for offload.
- D. Using virtual machine backup jobs with log shipping enabled, send this to a Scale-out Backup Repository and use Scale-out Backup Repository capacity tier for offload.
正解：D
解説：
Explanation
*Virtual machine backup jobs with log shipping enabled allow you to create image-level backups of SQL Server databases and also back up the transaction logs periodically12.
*Scale-out Backup Repository is a logical entity that groups several backup repositories into a single pool of storage, allowing for better backup performance, scalability, and management3.
*Scale-out Backup Repository capacity tier is a feature that allows you to offload older backup files to a public cloud object storage, such as Amazon S3 or Azure Blob Storage .
The other options are not as effective or efficient, as they either do not use Veeam features, do not offload to object storage, or do not create image-level backups.

Upon additional investigation, it is uncovered that the virtual machines to be replicated with a one-hour time have several separate large VMDKs with a high change rate per virtual machine on the same datastore. What mitigating techniques might be required?
- A. Use a dedicated Veeam Backup & Replication server just for replication.
- B. Implement Wan accelerator.
- C. Replicate to a single VMware datastore used just for replicas.
- D. Recommend migrating some of the VMDKs to alternative datastore.
正解：B、D
解説：
Explanation
To design a solution that meets the replication requirement for Veeam University Hospital, you need to consider some of the mitigating techniques that might be required for the virtual machines that have several separate large VMDKs with a high change rate per virtual machine on the same datastore. This will help you to overcome some of the challenges and limitations that may affect the replication performance and efficiency, as well as the recovery point objective (RPO) of the organization.
According to the Veeam Backup & Replication Best Practice Guide, some of the mitigating techniques that might be required are:
*Implement WAN accelerator. This technique can help you to reduce the amount of data that needs to be transferred and processed between the source and target sites, by using caching, deduplication, compression, and encryption. You need to deploy a pair of WAN accelerators, one at the source site and one at the target site, and configure them in the replication job settings. This technique can improve the replication speed and efficiency, as well as save network bandwidth and storage space.
*Recommend migrating some of the VMDKs to alternative datastores. This technique can help you to avoid performance degradation and resource contention on the source datastore, by distributing the load and I/O across multiple datastores. You need to use VMware tools or commands, such as Storage vMotion or svmotion, to migrate some of the VMDKs to other datastores that have enough capacity and performance. This technique can improve the replication stability and reliability, as well as reduce the impact on the production environment.
Therefore, based on these techniques, the answer that describes which mitigating techniques might be required is A and C.
質問 # 66
How would you configure replication with seeding, considering this deployment will have a Veeam Backup Server in both the primary and secondary site?
- A. On the Veeam Backup & Replication server at the primary site, create a backup job and backup copy job sending data to the secondary site. At the secondary site, create a replica job pointing to therepository with the backup copy data.
- B. On the Veeam Backup & Replication server at the primary site, create a backup job of the source machine from the primary site. At the secondary site import seeding data from this backup job. Create a replica job pointing to this backup job using re-mapping.
- C. On the Veeam Backup & Replication server at the secondary site, create a backup job of the source virtual machine from the primary site. At the secondary site, create a backup copy job pulling the data from the primary and create a replica job pointing to the repository with the backup copy data.
- D. On the Veeam Backup & Replication server at the primary site, create a backup job of the source virtual machine from the primary site. At the secondary site, create a replica job pointing to the repository with the backup job data.
正解：D
解説：
Explanation
Option C uses replica seeding to reduce the network traffic during the initial replication. By creating a backup job of the source VM at the primary site and pointing the replica job to that backup repository at the secondary site, Veeam Backup & Replication can restore the VM from the backup and synchronize it with the latest state of the source VM. Then it can use the restored VM as a replica2 Reference: Replica Seeding and Mapping - User Guide for VMware vSphere
