Question

Options

• ADon't select the "Multizone" option when creating your managed instance group.
• BSpread your managed instance group over two zones and overprovision by 100%. (for Two Zone)
• CCreate a regional unmanaged instance group and spread your instances across multiple zones.
• DOverprovision your regional managed instance group by at least 50%. (for Three Zones)

• A
  20% (6)
• B
  73% (22)
• C
  7% (2)

Explanation

B is correct if one zone fails you still have 100% desired capacity in another zone C is incorrect because it won’t be able to handle the full load since, it’s unmanaged group and won’t auto scale accordingly. D is correct since you have at least total 150% desired capacity spread over 3 zones, each zone has 50% capacity. You’ll have 100% desired capacity in two zones if any single zone failed at If you are creating a regional managed instance group in a region with at least three zones, Google recommends overprovisioning your instance group by at least 50%.
