Within a Compute Engine managed instance group (MIG) configured for autoscaling, what happens when CPU utilisation across the group sustains above the target threshold?
AThe MIG migrates the workload to BigQuery
BThe MIG immediately deletes all VMs to save money
CThe MIG halves the price of every VM in the group
DThe MIG adds VMs (scales out) up to the configured maximum size
Answer & Solution
Correct answer: D. The MIG adds VMs (scales out) up to the configured maximum size
An autoscaled MIG scales out (adds VMs) when load is high, up to the maximum size, and scales in when load drops. It doesn't delete everything, migrate to BigQuery, or change pricing.
