During a trend analysis for a cloud deployment, a cloud administrator notices sudden and unexplained spikes in resource consumption that do not align with the expected patterns or baselines. What is the BEST course of action for the cloud administrator to take in identifying the cause of these anomalies?
Immediately upgrade the hardware resources to handle any future spikes in demand.
Investigate for any changes or events that coincide with the timing of the anomalies.
Compare the spikes with known usage patterns and baselines to confirm the anomalies.
Ignore the anomalies assuming they are outliers with little impact on overall performance.
