Objective 1.4

Creating a migration plan

Objective 1.4 sits in Designing and planning a cloud solution architecture, which carries 25% 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.

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

1-4Designing and planning a cloud solution architecture

A team has to clear an expiring data center lease in the shortest elapsed time and accepts that the workloads will not use cloud features at first. Which migration type matches that plan?

Refactor, moving and improving the workloadImproving each workload adds the time this deadline does not allow.
Rehost, with minimal changes to the workloadCorrect · your answerCorrect. Speed bought by leaving the workload as it is.
Rebuild, replacing the workload entirelyA full replacement is the slowest option on the list.
Repurchase, adopting a different productBuying a different product changes the workload rather than moving it.

Correct.

Concept

Migration types trade elapsed time against how much of the destination you get to use, and a deadline set by something outside the project usually decides which end of that trade you take.

Why B

Rehost migrations keep refactoring to a minimum and tend to be the quickest, but the migrated workloads are not optimized for the cloud and miss features such as horizontal scalability and fine-grained pricing.

Source

Because you migrate existing workloads with minimal refactoring, rehost migrations tend to be the quickest, compared to refactor or rebuild migrations. However, after a rehost migration, the workloads that are running in the target environment aren't optimized for the cloud. These workloads don't take full advantage of cloud platform features, such as horizontal scalability, fine-grained pricing, and highly managed services.

Now you: objective 1.4 questions

No account needed. The explanation opens when you answer.

Sample question 1 of 3

1-4Designing and planning a cloud solution architecture

An engineer finds a workload whose build process cannot produce new artifacts after a source change, and the business will not decommission it. What does that combination force?

Sample question 2 of 3

1-4Designing and planning a cloud solution architecture

An organization wants elastic computing and redundancy out of its move and accepts several rounds of testing against a changed underlying platform, such as containers on GKE. Which migration type is that?

Sample question 3 of 3

1-4Designing and planning a cloud solution architecture

A team plans to take one large monolithic workload and turn it into several independent microservices deployed on Google Cloud. Which migration type does that describe?
