VMCA2022 Exam Dumps - Veeam Certified Architect 2022

To design a solution that meets the virtual infrastructure requirements for Veeam University Hospital, you need to collect some information during the discovery phase. This information will help you to understand the configuration and performance of the VMware clusters, 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 related to the virtual infrastructure that is missing and must be collected during the discovery phase are:

•Local area network speed. This information will help you to determine the network bandwidth and throughput that are available for backup and replication traffic, as well as the impact of backup and replication activities on the network performance and latency.

•Size of the source data set. This information will help you to estimate the backup storage requirements, as well as the backup compression and deduplication ratios, based on the size and type of the data.

Therefore, the correct answer is A and D.

To design a solution that meets the needs and requirements of Veeam University Hospital, you need to consider some of the risks and challenges that may affect the success and quality of the project. This will help you to identify and mitigate any potential issues or errors that may arise during the implementation or operation of the solution.

According to the Veeam Backup & Replication Best Practice Guide, a risk is a factor that may negatively impact the performance, reliability, security, or functionality of the backup and replication solution. A risk may be caused by internal or external factors, such as technical limitations, environmental constraints, human errors, etc.

Based on this definition, one of the possible risks for this project is C. Data must be replicated with one-hour recovery point objective.

This risk means that:

•The recovery point objective (RPO) is a business requirement that defines the maximum acceptable amount of data loss in case of a disaster or failure. It is measured in time units, such as minutes, hours, or days.

•The data replication is a technical solution that allows you to create replicas of your running workloads on another host or site. It is used for disaster recovery purposes, as it enables you to quickly fail over and fail back in case of a disaster.

•The one-hour RPO is a challenging and demanding requirement that may be difficult toachieve or maintain, depending on various factors, such as the data change rate, the available bandwidth, the replication frequency, etc.

•The one-hour RPO may also conflict or contradict with other requirements or expectations, such as the backup window, the backup retention, the backup storage capacity, etc.

This risk has some implications for designing a solution with Veeam products and features, such as:

•The customer or a third-party vendor must monitor and measure the data change rate of the workloads that need to be replicated, as well as the available bandwidth between sites. This will help to plan and optimize the replication infrastructure, such as the proxy servers, repository servers, WAN accelerators, and failover plans, based on the data change rate.

•The customer or a third-party vendor must configure and adjust the replication settings and policies, such as the replication method, schedule, frequency, retention, compression, deduplication, etc., based on the one-hour RPO. This will help to improve the replication performance and efficiency, as well as to meet the RPO requirement.

•The customer or a third-party vendor must test and verify the replication results and processes, as well as perform regular failover and failback drills. This will help to ensure the reliability and consistency of the replicas, as well as to validate and improve the RPO achievement.

To design a disaster recovery solution that meets the needs and requirements of Veeam University Hospital, you need to identify some information during the discovery phase. This information will help you to understand the scope and scale of the replication and failover processes, the network andstorage resources and limitations, and the recovery time objectives and recovery point objectives.

According to the Veeam Backup & Replication Best Practice Guide, some of the information that is necessary to design the disaster recovery solution and must be identified during discovery are:

•The number of virtual machines to be replicated. This information will help you to determine the number and size of the replication jobs, as well as the replication performance and scalability, based on the number and type of virtual machines.

•The available bandwidth between locations. This information will help you to estimate the network bandwidth and throughput that are available for replication traffic, as well as the impact of replication activities on the network performance and latency.

•Which sites will be the source of replication and which sites will be the targets for recovery. This information will help you to plan and configure the replication infrastructure, such as the proxy servers, repository servers, WAN accelerators, and failover plans, based on the source and target locations.

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.

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

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.

The configuration that is unsupported by Veeam Plug-in for Oracle RMAN based on the technical requirements is physical windows server with Oracle. Veeam Plug-in for Oracle RMAN only supports Oracle databases running on Linux, Solaris, or AIX operating systems1. The other configurations are supported by either Veeam Plug-in for Oracle RMAN or Veeam Backup & Replication. References: Veeam Plug-in for Oracle RMAN, Oracle | Veeam Backup & Replication Best Practice Guide.

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 networkperformance and backup SLAs3) or not supported (option C, as virtual proxies with more than eight CPUs are not compatible with Virtual appliance mode). References: Transport Modes, Virtual Appliance Mode, Direct Storage Access Mode, [Requirements and Limitations for VMware Backup Proxies].
