Exercise 2: Fixing the Real Default Zero-Second Eviction Notice — Possible Solution
====================================================================

GCP's own real default preemption notice for Spot VMs is 0 seconds -
meaning, under the default configuration, an instance can be
reclaimed with genuinely no advance warning at all. A workload that
needs at least a few seconds to save its own state gracefully before
shutting down would have no real opportunity to do so under this
default behavior; it could simply be terminated mid-operation with
zero notice.

This is a real, genuine risk specifically because the team is relying
on the default configuration rather than explicitly changing it. GCP
does support a longer notice period, but only if it's specifically
requested - it isn't the automatic behavior.

ANSWER: This default is a genuine risk because it provides no
advance warning at all before termination, giving the workload zero
real opportunity to save state gracefully. The specific fix is to
explicitly configure the Spot VM's own preemption notice setting to
the maximum real available window of 120 seconds, giving the
workload's own shutdown script a real, meaningful amount of time to
complete graceful cleanup before the instance is actually reclaimed.

WHY THIS WORKS AS AN ANSWER
------------------------------
This correctly identifies that the real risk comes specifically from
relying on the DEFAULT (0 seconds), not from Spot VMs being
inherently unsuitable for this workload, and names the specific real
configuration change (opting into the 120-second notice) rather than
suggesting the team abandon Spot VMs entirely.
