You have an application that sends banking events to Bigtable cluster-a in us-east. You decide to add cluster-b in us-central1. Cluster-a replicates data to cluster-b.

What deployment strategy should you use?
A) Use the default app profile with single-cluster routing.
B) Use the default app profile with multi-cluster routing.
C) Create a custom app profile with multi-cluster routing.
D) Create a custom app profile with single-cluster routing.

I disagree, A is too limiting for this setup.

Wait, single-cluster routing? That sounds risky!

I think B could work too, but not as reliable.

Definitely C! Custom profiles are more flexible.

Multi-cluster routing is the way to go!

I’m leaning towards option C, but I need to double-check if a custom app profile is really required for automatic routing.

I feel like the default app profile might not handle failover properly, but I can't recall the specifics.

I think we practiced a similar question where multi-cluster routing was necessary to ensure high availability.

I remember studying about multi-cluster routing, but I'm not sure if we need a custom app profile for this scenario.

Hmm, I'm a bit confused by this one. I'm not sure if a steep learning curve necessarily means a rapid reduction in time. Maybe option C or D could also be correct. I'll have to think this through carefully.

Assessing the risk of negative media coverage is important, but I think the first step should be to discuss this with the governance board. They'll have a better handle on the bigger picture and can help guide the next moves.

Hmm, I'm a bit unsure about this one. I know Cloud Build can trigger Spinnaker, but I'm not sure if that's the most efficient approach. Maybe I should look into the other options, like using Cloud Pub/Sub or a custom builder in Cloud Build to trigger a Jenkins pipeline. I'll need to do some research to figure out the best approach.
