The correct answer is C. A closer datacenter to the university. For a massive compute workload like DNA decoding, a geographically closer datacenter minimizes data transfer latency and maximizes throughput when moving large genomic datasets between the university and the cloud.

Cloud Architecture and Design

Question

A university is running a DNA decoding project that will take seven years if it runs on its current internal mainframe. The university negotiated a deal with a large cloud provider, which will donate its cloud resource to process the DNA decoding during the low peak time throughout the world. Which of the following is the MOST important resource the university should ask the cloud provider to donate?

Options

  • AA large storage for the DNA decoding results
  • BA larger pipe to transfer the results
  • CA closer datacenter to the university
  • DAny available compute resource

Why each option

For a massive compute workload like DNA decoding, a geographically closer datacenter minimizes data transfer latency and maximizes throughput when moving large genomic datasets between the university and the cloud.

AA large storage for the DNA decoding results

Storage for results is a secondary concern - it is needed, but it does not affect the speed or feasibility of the compute processing itself.

BA larger pipe to transfer the results

A larger network pipe improves bandwidth but does not reduce latency, and a distant high-bandwidth link is still slower for large sequential transfers than a nearby lower-bandwidth link.

CA closer datacenter to the universityCorrect

Genomic datasets are extremely large, and the round-trip time for uploading raw DNA data and downloading decoded results is directly tied to the physical distance to the datacenter. A closer datacenter reduces network latency and improves effective bandwidth utilization, which can be the primary bottleneck when transferring petabyte-scale datasets. Since compute is already being donated, geographic proximity is the most impactful additional resource to negotiate.

DAny available compute resource

Compute resources are already the subject of the donation arrangement described in the question; asking for any available compute does not address the data transfer challenge inherent in a remote processing model.
