Reference the exhibit.
A university campus has a site topology illustrated in the exhibit. Adjacent connected buildings are connected with a single 40gb layer 3 network with a RTT of
0.6ms as depicted by each line. An architect wants to configure a fault domain in each building.
What would the architect need change in order to implement a fully supported vSAN Cluster?
To implement a fully supported vSAN Cluster, it is necessary to enable a single Layer 2 network across all buildings for vSAN connectivity. This ensures that all nodes in different buildings are on the same Layer 2 domain and can directly communicate with each other, which is a fundamental requirement for vSAN to function correctly. Reducing RTT or adding redundant links would not address the Layer 2 network requirement, and enabling IPv6 is not relevant to the Layer 2 connectivity requirement.
When designing a vSAN Cluster, which three should be considered when sizing a vSAN datastore? (Choose three.)
When designing a vSAN Cluster, it is crucial to consider the following aspects for sizing a vSAN datastore: the Storage Policy or Policies to be used, as these define the characteristics and requirements of the stored data; vSAN Slack Space, which is essential for maintaining optimal performance and preventing the system from running out of available space; and On-Disk Format overhead, which accounts for the space used by the system to manage and store data on the drives. These factors directly impact the available storage capacity and overall efficiency of the vSAN environment.
Which must be configured by a Kubernetes user allow for dynamic provisioning of container volumes in vSAN using storage policies?
To allow for dynamic provisioning of container volumes in vSAN using storage policies, a Kubernetes user must configure a StorageClass. The StorageClass object in Kubernetes provides a way for administrators to define different classes of storage, each with their own policies and parameters, such as replica numbers, encryption, or performance characteristics. When a PersistentVolumeClaim (PVC) requests storage with a particular StorageClass, the associated storage policy is applied to dynamically provision the storage accordingly.
An All-Flash vSAN cluster has 4 nodes with this disk group composition on each host:
✑ 1 × 800 GB SAS SSD
✑ 6 × 3.84 TB SATA SSD
An administrator observes that in an All-Flash cluster, the Write Buffer Free Percentage is consistently low. As a result, there is increased latency experienced by the workloads.
Which remediation steps will resolve this issue?
The consistent low Write Buffer Free Percentage in the All-Flash cluster is an indicator that the current cache device is being overwhelmed due to insufficient caching capacity. Adding a second disk group with a new cache device and distributing the capacity disks equally will significantly increase the overall caching capacity. This approach does not require replacing existing hardware, thereby avoiding the complexity and higher costs associated with changing cache devices in existing disk groups. It also allows for better scalability and utilization of cache resources, improving the efficiency and performance of the write buffer.
An administrator receives an alert for vCenter being unavailable. With vCenter running on vSAN, the administrator wants to know if any other VMs are impacted.
What command can an administrator run to determine the overall health of the vSAN objects?
To determine the overall health of the vSAN objects, the command 'esxcli vsan health cluster list' should be used. This command provides a comprehensive overview of the health status of the vSAN cluster, including any issues with the vSAN objects. This allows administrators to quickly assess the health and functionality of the vSAN environment.
