Q: 1
A microservice running on Cloud Run needs to connect to an external on-premises
database via a Dedicated Interconnect connection. What is the required networking
configuration for the Cloud Run service?

C. encountered exactly similar question in my exam and this is the setup needed for Cloud Run to reach on-prem over Interconnect.
D, not C
Maybe D, but only if the on-prem DB had a public IP instead of being accessed over Interconnect using private IPs. Otherwise C feels right for this scenario.
D. saw a similar question pop up in some practice sets.
Option C is the right pick, not D. Assigning an external IP (option D) seems tempting but doesn't enable private connectivity to on-prem via Interconnect-that's what Serverless VPC Access does. I see folks mix that up a lot in practice.
Probably C since Serverless VPC Access is needed for Cloud Run to hit internal IPs over Interconnect. Assigning an external IP (D) doesn't help with on-prem private resources, that's a common trap here. I think this lines up with how Google expects you to connect hybrid workloads, but happy for any corrections.
C/D? D is tempting but only works for public IPs, not private over Interconnect. C is correct in this context.
Nah, D seems like a trap since assigning an external IP won't help Cloud Run reach on-prem private IPs over Interconnect. C is what you need for private connectivity. Anyone disagree?
I'd say D makes sense here. If you assign an external IP to the Cloud Run service, it should be able to connect out to external resources like an on-prem database, assuming firewall rules allow it. I remember seeing a similar setup in a practice set, so I think D works, but open to other ideas if I'm missing a detail.
C vs D? Not totally confident, but pretty sure C is right since Serverless VPC Access is usually needed for private connections back to on-prem. D doesn't really let Cloud Run reach internal IPs over Interconnect, if I'm remembering this right.
Be respectful. No spam.
