   A VKS cluster is running a stateful application that is experiencing periodic slowdowns. The administrator needs to determine whether the slowdowns correlate with specific times of day or with other workloads on the same ESXi hosts. Which vCenter performance chart view should the administrator use to analyze this data most effectively?

   • AThe 'Past Day' view for the VKS node VMs, comparing CPU and memory metrics
   • BThe 'Past Week' view for the VKS node VMs and the ESXi hosts, overlaying metrics to spot correlations
   • CThe 'Past Month' view for the VKS namespace, focusing on storage I/O metrics
   • DThe 'Realtime' view for the VKS node VMs, set to a 1-minute interval

   Which scaling action is most appropriate when a VKS cluster needs more storage for persistent volumes?

   • AEnable vSphere HA on the cluster
   • BAdd more vCPUs to the VKS nodes
   • CAdd a new datastore to the cluster
   • DIncrease the memory limit on the VKS nodes

   An administrator wants to be notified proactively when the memory usage of a VKS node VM exceeds 90% for more than 5 minutes, so they can investigate before the workload degrades. The VM is in a vSphere Supervisor cluster. What is the most efficient way to set up this monitoring?

   • ACreate a vCenter alarm on the VKS node VM for the 'Memory Usage' metric with a warning threshold of 90% and a condition that lasts for 5 minutes
   • BEnable the 'High Memory Usage' alarm on the ESXi host and set the threshold to 90%
   • CUse the VKS namespace's built-in resource quota monitoring to alert on memory usage
   • DConfigure a scheduled task in vCenter to run a PowerCLI script every 5 minutes that checks memory usage and sends an email
