Each deployment requires a unique set of configuration values. You want to provide these unique values to each deployment but use the same custom machine image in all deployments. You want to use out-of-the-box features of Compute Engine. What should you do?

Wait, can you really use instance metadata for this? Sounds too easy!

A is a no-go, persistent disks are for storage, not config.

Not sure about D, wouldn’t the startup script be more flexible?

D seems like the best option for instance-specific values.

Cloud Bigtable seems overkill for just configuration values. I lean towards instance metadata, but I wish I had more clarity on the implications.

I feel like using persistent disks is not ideal for this scenario since we want to keep it simple and use out-of-the-box features.

I think placing values in the startup script could work, but it might complicate things if we have to change configurations frequently.

I remember we discussed using instance metadata for passing configuration values in class. It seems like a good fit here, but I'm not entirely sure if it's the best option.

Option A looks good to me. Splitting the employee addition and payroll processing between different teams, plus the automatic deposit, seems like it would make it harder for anyone to commit fraud.

Hmm, I'm a bit unsure about this one. I know stakeholder engagement is important, but I'm not sure what specific factors can increase the complexity. I'll need to review my notes on stakeholder management to make sure I understand the key considerations.

Okay, let's see. A large number of accounts were compromised, so it's probably not just a poorly configured firewall. Malware or an APT seem more likely, but I'll need to weigh the evidence.
