VMCA2022 Exam Dumps - Veeam Certification Questions and Answers

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

•Veeam CDP is a technology that helps you protect mission-critical VMware virtual machines when data loss for seconds or minutes is unacceptable12.

•Veeam CDP leverages vSphere APIs for I/O filtering (VAIO) to constantly replicate I/O operations performed on VMs without creating snapshots12.

•Veeam CDP allows you to configure the RPO per second and achieve near-zero RPO, which means almost no data loss12.

•Veeam CDP also provides minimum recovery time objective (RTO) in case of a disaster, as CDP replicas are in a ready-to-start state1.

Veeam image-based replication is not the best option, as it relies on snapshots and has a higher RPO than CDP3. Custom PowerShell scripting is not a reliable or scalable solution, as it requires manual coding and maintenance. Veeam Backup Copy with immediate mode is not suitable for replication, as it is designed for copying backup files, not VM replicas4.

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.

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.

•Use Hardened Repositories as the primary target, which are Linux-based repositories that support immutability and prevent ransomware from accessing or deleting backup files12.

•Use backup copy jobs to create a second copy of the backups to a different site, which will provide additional protection and redundancy in case of a disaster or data loss34.

•Use Veeam Backup & Replication servers at one location, which will simplify the management and monitoring of the backup infrastructure and reduce the operational costs.

The other configurations are not as effective or secure, as they either do not use immutability, do not create a second copy of the backups, or do not leverage the benefits of Veeam Backup & Replication servers.

Thank you for your question. I’m glad to help you with your VMCA 2022 project.?

To design a solution that meets the database requirements for Veeam University Hospital, you need to consider some of the options and features that can support and integrate with Oracle databases. This will help you to ensure the consistency and reliability of the Oracle backups and restores, as well as the compatibility and supportability of the native Oracle tools with Veeam products and features.

According to the Veeam Backup & Replication Best Practice Guide, the option that most closely matches the requirements of having native Oracle utilities available for backups and restores is D. Install the Veeam RMAN Plug-in to allow native RMAN backups and restores to leverage Veeam repository directly from the Oracle servers.

This option means that:

•The Veeam RMAN Plug-in is a solution that integrates with Oracle Recovery Manager (RMAN) and allows you to back up and restore Oracle databases using Veeam repositories as targets.

•The Veeam RMAN Plug-in supports both virtual and physical Oracle servers, as well as different versions and editions of Oracle databases.

•The Veeam RMAN Plug-in enables you to use native Oracle tools and commands, such as RMAN, SQL*Plus, Data Pump, etc., to perform backups and restores of Oracle databases, without requiring any additional scripts or configurations.

•The Veeam RMAN Plug-in leverages the benefits and features of Veeam Backup & Replication, such as backup compression, deduplication, encryption, immutability, etc., to improve the backup performance and efficiency, as well as the backup security and integrity.

This option is the best match for the requirements, as it allows you to use native Oracle utilities for backups and restores, while also taking advantage of Veeam products and features.

•The RMAN plugin is a component that integrates Veeam Backup & Replication with Oracle RMAN, which is a native tool for Oracle backup and recovery12.

•The RMAN plugin allows you to use Oracle RMAN commands to back up and restore Oracle databases to Veeam backup repositories, as well as perform log shipping and point-in-time recovery12.

•The RMAN plugin supports Oracle databases running on any supported operating system or hypervisor, as well as physical servers or cloud environments12.

•The RMAN plugin leverages the features and benefits of Veeam Backup & Replication, such as compression, deduplication, encryption, scalability, and reliability12.

To design a solution that meets the needs and requirements of Veeam University Hospital, you need to gather some information during the discovery phase. This information will help you to understand the current state of the environment, the goals and expectations of the stakeholders, and the constraints and challenges of the project.

According to the Veeam Backup & Replication Best Practice Guide1, some of the information that is necessary for designing a solution and must be gathered during discovery are:

•Operating systems used to run the workloads. This information will help you to determine the compatibility and supportability of the workloads with Veeam products and features, as well as the licensing and configuration requirements.

•Allowed backup windows. This information will help you to plan and schedule the backup jobs according to the availability and performance of the workloads, as well as the service level agreements (SLAs) and recovery point objectives (RPOs) of the organization.

•Amount of used disk space. This information will help you to estimate the backup storage requirements, as well as the backup compression and deduplication ratios, based on the type and size of the data.

To perform backup from storage snapshots for a Fibre Channel SAN, you need to deploy one or more physical servers that will act as backup proxies and connect them to the SAN fabric. This is because Veeam Backup & Replication needs to access the storage system over the Fibre Channel protocol, which is not supported by virtual machines. The backup proxies will read data from the storage snapshots and transfer it to the backup repositories1

To design a solution that meets the offsite copies and archives requirements for Veeam University Hospital, you need to clarify some of the assumptions and expectations of the customer. This will help you to avoid any misunderstandings or conflicts that may arise during the implementation or operation of the solution.

According to the Veeam Backup & Replication Best Practice Guide, offsite copies and archives are two different concepts that serve different purposes. Offsite copies are backups that are stored in a different location than the primary backup storage, and are used for disaster recovery purposes. Archives are backups that are stored for a longer retention period than the regular backups, and are used for compliance or historical purposes.

Based on these definitions, the requirement that needs additional information to help clarify the customer expectation is C. Backups must take advantage of public cloud storage for long term archival purposes.
