Question: 1
You are asked to deploy a new application that has been designed to scale horizontally. The business stakeholders have asked that the application be deployed In us-phoenlx-1.
Normal usage requires 2 OCPUs. You expect to have few spikes during the week, that will require up to 4 OCPUs, and a major usage uptick at the end of each month that will require 8 OCPUs.
What is the most cost-effective approach to implement a highly available and scalable solution?
A. Create an instance pool with a VM.Standard2.2 shape instance configuration. Setup the autoscaling configuration to use 2 availability domains and have a minimum of 2 instances, to handle the weekly spikes, and a maximum of 4 Instances.
B. Create an instance with 1 OCPU shape. Use a CLI script to clone It when more resources are needed.
C. Create an instance pool with a VM.Standard2.1 shape instance configuration. Setup the autoscaling configuration to use 2 availability domains and have a minimum of 2 instances and a maximum of 8 instances.
D. Create an instance with 1 OCPU shape. Use the Resize Instance action to scale up to a larger shape when more resources are needed.
Answer: A
