The correct answer is D. Disk utilization. High disk utilization is the most likely metric to indicate a violation of an SLA requiring redundancy for two host failures, as it can prevent proper data replication or recovery processes.
Question
A new private cloud platform is being deployed by an engineer. SLA requirements state that any clusters should have a baseline redundancy sufficient to handle the failure of at least two hosts. The engineer records the following metrics after the deployment:
Which of the following metrics is MOST likely to represent a violation of SLA?

Why each option
High disk utilization is the most likely metric to indicate a violation of an SLA requiring redundancy for two host failures, as it can prevent proper data replication or recovery processes.
High RAM utilization primarily impacts performance and the ability to host more virtual machines, but it does not directly compromise data redundancy mechanisms designed to survive host failures.
High NIC utilization affects network throughput and latency but does not inherently compromise the system's ability to maintain data redundancy across multiple host failures.
High CPU utilization affects processing power and application performance but does not directly compromise the data protection or redundancy mechanisms against host failures.
High disk utilization, particularly in shared or clustered storage capacity, indicates that there may not be sufficient free space to re-replicate data or recover from the failure of two hosts, directly compromising the SLA's redundancy requirement.
