Selected Answer: CE

C. Increase Parallel Jobs: By splitting the architecture compilation tasks into multiple jobs running concurrently, you can significantly reduce the total build time. Each job can focus on a specific architecture, leading to parallel processing and faster overall execution. E. Create an Agent Pool: Using an agent pool allows you to define a set of build agents (virtual machines) that can run pipeline jobs. By scaling up the number of agents in the pool, you can distribute the workload across multiple machines, further accelerating the parallel execution of your jobs.

This question is silly and ambiguous. "10 different architectures" - architecture of what ? 10 different hardware specs ? 10 different processors ? 10 different OS ? 10 different solutions ? 10 different frameworks of a given language? 10 what , exactly ? Also, why increase the pool ? Why can't a pool with multiple agents do the same job ?

I thought C already included E. Then, why not consider D - reduce size of the repos (it will take long time to decouple things... - but is it better for the long run)

This is C and E for sure "reduce the time" so more jobs in an agent pool

I think the correct answer is C and E. You can find the explanation to the question "I need more hosted build resources. What can I do?" in the faqs of the article below: https://docs.microsoft.com/en-us/azure/devops/pipelines/agents/pools-queues?view=azure-devops&tabs=yaml%2Cbrowser#faq
