Question 400
An enterprise architecture team faces this design requirement: Large fault-tolerant batch analytics jobs can be interrupted and resumed while the team pays full on-demand prices. What is the most appropriate design for this workload?
Explanation
Correct Answer
Spot Instances optimize interruptible capacity costs when jobs tolerate reclaim events. The required architecture outcome is: Large fault-tolerant batch analytics jobs can be interrupted and resumed while the team pays full on-demand prices. Validate this choice by checking that A simulated interruption causes bounded rework and lowers total compute cost without losing final results.
Incorrect Answers
Objects remain indefinitely in higher-cost storage despite a proven low-access retention pattern. The specific problem here is that the workload uses only on-demand capacity despite safe restart or checkpoint semantics.
S3 calls egress through NAT because no supported endpoint route was configured. The specific problem here is that the workload uses only on-demand capacity despite safe restart or checkpoint semantics.
Backup administrators can freely delete critical recovery points despite required immutability. The specific problem here is that the workload uses only on-demand capacity despite safe restart or checkpoint semantics.
