Authentic Veeam Certification Exam VMCA2022 Questions 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.
