Google Professional Cloud Database Engineer Exam - Topic 11 Question 23 Discussion

Actual exam question for Google's Professional Cloud Database Engineer exam
Question #: 23
Topic #: 11
[All Professional Cloud Database Engineer Questions]

Your company is migrating all legacy applications to Google Cloud. All on-premises applications are using legacy Oracle 12c databases with Oracle Real Application Cluster (RAC) for high availability (HA) and Oracle Data Guard for disaster recovery. You need a solution that requires minimal code changes, provides the same high availability you have today on-premises, and supports a low latency network for migrated legacy applications. What should you do?

Show Suggested Answer Hide Answer
Suggested Answer: D

BMS is the only Google database service which supports Oracle aside from GCVE. It allows you to use all native Oracle features including RAC. Since GCVE isn't mentioned, it has to be D - Bare Metal Solution.

Wait, can Cloud Spanner really match Oracle RAC HA?

Bare Metal Solution sounds familiar, and I think it might be the best choice for legacy Oracle databases, but I’m a bit unclear on how it handles disaster recovery compared to the others.

I practiced a similar question where we had to choose between Cloud SQL and Compute Engine. I feel like Cloud SQL might be easier to manage, but I'm not sure about the HA aspect.

I think Cloud Spanner could work since it’s designed for scalability, but I’m not entirely confident it supports the same HA features as Oracle RAC.

I remember we discussed the importance of maintaining high availability during migrations, but I'm not sure which option best replicates Oracle RAC.

Bare Metal Solution for Oracle sounds interesting, but I'm not sure if that's the most cost-effective solution for our cloud migration.

Hmm, I'm a bit confused. The question mentions Oracle RAC and Data Guard, so I'm not sure if Cloud Spanner would be a good fit.

This is a tricky one. I'll need to carefully consider the requirements around minimal code changes, high availability, and low latency.

I think option B with Cloud SQL and a standby database could work well. That would provide the high availability we need without too many code changes.

Ah, this is a tricky one. I'll need to think through the security implications of each approach and make sure I'm not introducing any potential risks.

No direct access to UI elements? That's going to make this a real challenge. I'll need to get creative with my automation approach.

What about Cloud Spanner? That's Google's fully managed database service. It might be a good fit since it's designed for high availability and scalability.

Haha, can you imagine trying to migrate these Oracle RAC databases to Cloud SQL? Talk about a nightmare. That's definitely not the way to go.

Exactly, and we need something that can handle the complex SQL queries these legacy apps are using. Cloud Spanner might not be the best fit for that.

Good point, Sarah. But I'm not sure Cloud Spanner can match the low latency requirements we have for these legacy apps. It's more of a NoSQL-style database, right?
