Configuring compute systems

Objective 2.3 sits in Managing and provisioning a cloud solution infrastructure, which carries 17.5% of the Cloud Architect exam. The questions below are original, written from the official objective title above, and each explanation cites the Google Cloud page it rests on.

A worked example

Shown solved, with the whole explanation open: this is what every question here carries.

2-3Managing and provisioning a cloud solution infrastructure

An engineer reuses one aggressive health check for both load balancing and autohealing on a managed instance group. What does that reuse risk?

Traffic keeps reaching instances that stopped respondingAn aggressive check pulls traffic sooner rather than later.
Instances get deleted and recreated too readilyCorrect · your answerCorrect. A brief blip now costs a rebuild.
The group stops autoscaling under loadScaling policy is driven by load signals, not by this check.
Health checks cannot be shared at allSharing one check is possible, which is exactly the trap.

Correct.

Concept

Two checks that look alike have different consequences: one moves traffic and the other destroys a machine, so the sensitivity each can afford is not the same.

Why B

Load balancing health checks only steer traffic away from non-responsive instances, while managed instance group health checks proactively signal to delete and recreate instances that become UNHEALTHY.

Source

Load balancing health checks help direct traffic away from non-responsive instances and toward healthy instances; these health checks do not cause Compute Engine to recreate instances. On the other hand, managed instance group health checks proactively signal to delete and recreate instances that become UNHEALTHY .

2-3Managing and provisioning a cloud solution infrastructure

A database running on VMs must keep its instance names and attached persistent disks intact when the group recreates or updates an instance. Which capability provides that?
