Question-41: Most migrations happen in phases to minimize risk and speed up time to production. The most common approach is to lift-and-shift (also known as rehost) an application and its data with as few changes as possible. This enables the fastest time to production. Your company just finished a rapid lift and shift to Google Compute Engine for your compute needs. The Lift & Shift (a.k.a. Move & Improve) Cloud migration model moves your existing applications to run on virtual servers in the cloud, using public or private Cloud platforms, without redesigning or re-implementing your applications. You have another 9 months to design and deploy a more cloud-native solution. Specifically, you want a system that is no-ops and auto-scaling. Which two compute products should you choose? Choose 2 answers.
A. Compute Engine with containers
B. Google Kubernetes Engine with containers
C. Google App Engine Standard Environment
D. Compute Engine with custom instance types
E. Compute Engine with managed instance groups

: 2, 3 Explanation: Because the question says that you have 9 months, all 5 are legitimate choices. However, A is worse than the other 4. Also Option-2 and Option-3 come with the cloud as default and they are customizable, so they can be improved. This makes them better contenders than Option-4 and E, which are the basis of both Option-2 and C. In other terms, both Option-2 and Option-3 use Compute Engines with preset, but changeable configurations. No-ops means you cannot use Compute Engines as they are simple VMs. Kubernetes is nearly no-ops (remains some operations like nodes updates, but all-in-all Google manages nearly all the operations) App Engine is truly no-ops
