During the creation of a vSphere-based design solution, an architect identifies the following assumption:
The customer will be responsible for providing all licensing for the vSphere platform.
The storage hardware has sufficient capacity for future workload scale.
The data center offers sufficient power, cooling and rack space for workload scale.
When documenting each assumption within the design, which two corresponding pieces of information must the architect also define? (Choose two.)
The storage hardware may not have capacity for future workload scale:
While the assumption is that the storage hardware has sufficient capacity for future workload scale, it's important to acknowledge that there may be scenarios where the current storage capacity might not be sufficient. The architect must document this potential limitation as a risk to the design, ensuring that it is clear that the capacity assumption is not guaranteed.
Additional storage capacity can be procured to expand the solution in the future as needed:
This statement provides a mitigation strategy to address the assumption regarding storage capacity. If future scale requires more storage than initially provided, the design should include a strategy for procuring and integrating additional storage resources to meet demand as needed. This helps ensure scalability and adaptability in the future.
An architect is designing a new vSphere solution. The solution will be used to host workloads that have multiple dependencies. The customer provides the following information regarding the workloads:
Workload 1: Self-Service Portal
Workload 2: Database
Workload 3: Identity Broker
Workload 4: Reporting Tool
Workload 5: Management Tool
Application A is formed of workloads 1 and 2 and has a dependency on workload 3
Application B is formed of workloads 2 and 4 and has a dependency on workload 3
Application C is formed of workload 5 and has a dependency on workload 4
How should the architect document the vSphere HA requirements to ensure that all of the applications can be recovered in the event of a host failure while observing the dependencies?
The goal here is to ensure that, in the event of a host failure, the workloads are restarted in the correct order based on their dependencies:
Workload 3 (Identity Broker) is required by both Application A and Application B as a dependency. It needs to be set to High Restart Priority, ensuring that it is restarted before the other dependent workloads.
Workload 4 (Reporting Tool) is required by Application B and Application C, so it should be set to High Restart Priority to ensure it is available before the other dependent workloads (like Workload 5).
Workload 5 (Management Tool) is required by Application C and should have a Medium Restart Priority, meaning it will be restarted after Workload 4.
Workloads 1 and 2 (Self-Service Portal and Database) have Low Restart Priority because they are dependent on Workload 3 (and Workload 4), but they do not have further critical dependencies after Workload 3, so they should be restarted last in the event of a failure.
This setup ensures that all applications can be recovered properly in the event of a host failure, with each workload restarting in the correct order to maintain the application dependencies.
An architect is designing a vSphere-based application hosting solution in a brownfield site.
The following information has been provided during the requirements gathering workshop:
The solution should support 5,000 compute workloads across two physical sites.
The CFO has approved budget for the purchase of new server and network hardware only.
The existing storage array is currently Fibre Channel connected with 2 x 8Gbps interfaces to a dedicated Storage Area Network (SAN) fabric.
The existing storage array does not support integration with vSphere API for Storage Awareness.
The existing storage array can be configured to support NFS storage.
The existing vSphere administration team will responsible for operational management of the new solution.
Which storage technology should the architect recommend based on these requirements?
Based on the requirements provided, the architect should recommend iSCSI for the following reasons:
Existing Storage Array: The existing storage array does not support integration with vSphere API for Storage Awareness (VASA), which is required for vVols and VMware vSAN. This means that vVols and vSAN cannot be used without significant upgrades or changes to the storage infrastructure.
Existing Fibre Channel Connectivity: The storage array has Fibre Channel connectivity, but it is limited to 2 x 8 Gbps interfaces and is not compatible with advanced features required by modern solutions like vVols. In addition, Fibre Channel is traditionally complex to manage and requires specialized knowledge, which may not align with the existing vSphere administration team's expertise.
Support for NFS Storage: The storage array can be configured to support NFS storage, which is an efficient, simpler-to-manage option compared to traditional Fibre Channel or iSCSI. Since iSCSI is also IP-based, it aligns well with the existing vSphere environment.
Scalability and Simplicity: iSCSI allows for easy integration with vSphere and is a highly scalable option for expanding storage across two sites, which meets the requirement of 5,000 compute workloads across two physical sites. It is also easier to manage compared to Fibre Channel and vVols.
An architect is designing a new vSphere solution. The following information has been gathered during the design workshops with the customer:
The solution will be deployed into two availability zones (AZs)
The solution will be configured as a single stretched cluster with shared storage across the two AZs
Production and Development workloads will run across both AZs
The cluster is configured as N + 1
The architect needs to ensure that, in the event of a host failure during maintenance of another host in the cluster, only the Production workloads are recovered.
What should the architect include in the design to meet this requirement?
In this scenario, the requirement is to ensure that only Production workloads are recovered in the event of a host failure during maintenance, while Development workloads are not restarted. This can be achieved using vSphere HA settings.
By configuring the vSphere HA Host Failure Response to Restart VMs, the system will attempt to restart VMs when a host failure occurs.
Setting the Restart Priority for Development VMs to Disabled ensures that these VMs will not be restarted during a failure event, even though the cluster is set to restart VMs in the event of a host failure. This way, only the Production workloads will be restarted, meeting the customer's requirement.
An architect is documenting the design for a new vSphere cluster. The customer provides the following information:
All ESXi hosts will use hardware from the same vendor
All ESXi hosts will be monitored for hardware related issues using the vendor's monitoring tooling
The vendor's monitoring tooling provides a plugin for vCenter to allow the hardware status to be visible
The customer also informs the architect of the following requirements:
Workloads must be automatically relocated to other hosts in the event that a host hardware is marked as degraded.
Workloads must be automatically restarted on other hosts in the event of a host failure.
What should the architect include in the design to meet these requirements?
To meet the customer requirements, we need to address the two specific scenarios:
Workloads must be automatically relocated to other hosts in the event that a host hardware is marked as degraded:
This requirement can be fulfilled by Proactive HA. Proactive HA is a feature of vSphere HA that works in conjunction with hardware health monitoring tools, such as the vendor's plugin for vCenter. When the vendor's monitoring tool marks a host as degraded (due to hardware issues), Proactive HA can automatically trigger the migration of workloads to other hosts, based on the Automation Level configuration.
Workloads must be automatically restarted on other hosts in the event of a host failure:
This can be managed using vSphere HA with the setting to restart VMs when a host fails. This ensures that in the event of a host failure, workloads are automatically restarted on available hosts in the cluster.
By enabling Proactive HA with an Automation Level of Automated, the architect ensures that degraded hosts are automatically handled (through workload migration) without manual intervention.
