Answer : C

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.

Answer : C, E

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.

Answer : D

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 period expires. 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.

Answer : C

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 to achieve 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.

Answer : D

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.

Answer : B, D, F

The things that can be done to validate that the design meets target SLAs and reduces the headcount required to manage the solution are:

Use tagging and scripts to auto-generate backup jobs, set the start time and windows, letting the backup server manage resource allocation.This option allows to automate the backup job creation and configuration, based on the tags assigned to the source objects, such as VMs, hosts, or clusters1.This reduces the manual effort and human error involved in managing the backup jobs, and ensures that the backup server allocates the optimal resources for each job, based on the load balancing and performance settings2.

Explain how to detect configuration changes, reporting and using backup job templates to maintain consistency. Document self-service restore the streamline service desk engagement.This option allows to monitor the backup infrastructure and detect any changes that may affect the backup performance or reliability, such as adding or removing VMs, hosts, or clusters3.It also allows to use backup job templates to create consistent and standardized backup policies, and apply them to multiple backup jobs4.Additionally, it allows to document the self-service restore process, which enables end-users to perform file-level restores from their own backups, without involving the backup administrator or the service desk5.

Review the design so that the slowest part of the infrastructure is fast enough to meet backup window requirements. This option allows to identify and optimize the bottleneck in the backup infrastructure, which is the component that limits the backup speed and throughput. By reviewing the design and ensuring that the slowest part of the infrastructure can meet the backup window requirements, the backup SLAs can be achieved and the backup performance can be improved.

The other options are either not relevant for validating the design (option A and E, as exporting the configuration, scheduling a review, and reviewing the design for bottlenecks are part of the design process, not the validation process) or not effective for meeting the SLAs and reducing the headcount (option C, as using inventory information, backup chaining, and fine tuning are manual and complex tasks that may not guarantee the backup window compliance or resource efficiency).Reference:Tagging,Load Balancing and Performance,Configuration Change Tracking,Backup Job Templates,Self-Service File Restore, [Bottleneck Statistics]

To design a solution that meets the needs and requirements of Veeam University Hospital, you need to collect some critical 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 case study, some of the critical information that was missing from discovery are:

* Size of current data sets. This information is critical because it helps you to estimate the backup storage requirements, as well as the backup performance and efficiency, based on the size and type of data. You need to know how much data is stored on each workload, such as virtual machines, physical servers, NAS systems, etc., as well as how much data is changed or added on a daily or weekly basis.

* Backup retention policy. This information is critical because it helps you to define the backup retention settings and policies, such as the number and frequency of backup copies, the backup storage tiers, the backup deletion rules, etc. You need to know how long the backup data should be kept for compliance or historical purposes, as well as how much backup storage capacity is available or needed.
