AWS Certified SysOps Administrator - Associate SOA-C02 — Topic 1 Question 13

Question

A company is running distributed computing software to manage a fleet of 20 Amazon EC2 instances for calculations. The fleet includes 2 control nodes and 18 task nodes to run the calculations. Control nodes can automatically start the task nodes. Currently, all the nodes run on demand. The control nodes must be available 24 hours a day, 7 days a week. The task nodes run for 4 hours each day. A SysOps administrator needs to optimize the cost of this solution. Which combination of actions will meet these requirements? (Choose two.)

Accepted Answer

Correct answer: A, E. The correct answer is A, E. Option A: Purchase EC2 Instance Savings Plans for the control nodes. Option E: Use Spot Instances for the task nodes. Use On-Demand Instances if there is no Spot availability. Spot Instances use spare capacity at a large discount, ideal for fault-tolerant or interruptible workloads. Savings Plans reduce cost for consistent compute usage in exchange for a usage commitment. Amazon EC2 provides resizable virtual servers when you need full control of the operating system.
