For any replicated virtual workloads, the data must not be more than one hour old. What could be a potential risk to the SLA for the offsite disaster recovery aspect of this requirement?
To design a disaster recovery solution that meets the requirement of having the replicated virtual workloads data not more than one hour old, you need to consider some of the potential risks and challenges that may affect the service level agreement (SLA) for the offsite disaster recovery aspect of this requirement. This will help you to ensure the availability and reliability of the replication and failover processes, as well as the recovery time objective (RTO) and recovery point objective (RPO) of the organization.
According to the Veeam Backup & Replication Best Practice Guide, one of the potential risks to the SLA for the offsite disaster recovery aspect of this requirement is B. Data change rate.
This risk means that:
* The data change rate is the amount of data that is modified, added, or deleted in a given time period. It is usually measured in percentage or megabytes per hour.
* The data change rate affects the replication performance and efficiency, as it determines how much data needs to be transferred and processed between the source and target sites.
* The data change rate also affects the replication frequency and consistency, as it determines how often and how accurately the replicas are updated and synchronized with the source workloads.
* The data change rate may vary depending on the type and activity of the workloads, such as database, file server, web server, etc. Some workloads may have a high data change rate, while others may have a low data change rate.
* The data change rate may exceed the available bandwidth or storage capacity between the source and target sites, which may result in replication failures, delays, or errors. This may compromise the SLA for the offsite disaster recovery aspect of this requirement, as it may cause the replicated virtual workloads data to be more than one hour old.
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 and storage capacity between the source and target 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 data change rate. This will help to improve the replication performance and efficiency, as well as to meet the SLA for the offsite disaster recovery aspect of this requirement.
What information is necessary for designing a solution and must be gathered during discovery? (Choose 3)
Size of the backup create by the incumbent backup solution.
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.
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?
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.
Consider the requirements regarding immutable or air gapped and different types of workloads. Which types of jobs do not support using immutability from S3 Object Lock or Hardened Repository and will need a different solution?
* Backup copy jobs with GFS enabled. This type of job does not support using immutability from S3 Object Lock because it uses synthetic full backups, which require modifying existing backup files. Synthetic full backups are not compatible with immutability settings, as they violate the principle of not changing the backup files.
Based on the customer's security requirements around restore capabilities, which components should be deployed?
The component that should be deployed based on the customer's security requirements around restore capabilities is Enterprise Manager with granular RBAC policies defined. Enterprise Manager is a web-based interface that allows centralized management of multiple Veeam backup servers. It also provides granular RBAC policies that enable control over user permissions and access to restore data. For example, you can assign different roles to different users or groups based on their responsibilities and needs, such as backup administrator, restore operator, security officer, etc. You can also define custom scopes and rules for each role to limit their access to specific objects, jobs, or actions.
