Due to user complaints of slow VM performance, an administrator is reviewing performance metrics on their Nutanix cluster and executes `iostat` on a Controller VM (CVM). The following output is captured: `#TIMESTAMP 1768953673 : 016 12:01:13 AM` `avg-cpu: %user %nice %system %iowait %steal %idle`2 0.09 7.53 83.20 0.00 6.86` Based on this output, which statement most accurately describes the current state of the CVM?  

After logging into Prism Central, an administrator observes that there are a large number of constrained VMs. What does this indicate about those VMs?

An administrator manages a shared AHV environment where Dev workloads must not exceed 2,000 IOPS per VM during business hours to prevent noisy-neighbor impact on Prod. The administrator already uses categories to group VMs (for example, category Env=Dev) and wants a scalable approach that applies consistent throttling to all current and future Dev VMs without configuring each VM individually. Which approach best meets the requirement? 

An administrator wants to enable secure boot for a guest VM. Which condition would prevent the administrator from completing this task? 

An administrator added an SSH public key and verified connectivity to CVMs and AHV hosts. What is the recommended next step to reduce interactive access risk?
