You need to reduce the cost of virtual machines (VM) for your organization. After reviewing different options, you decide to leverage preemptible VM instances.
Which application is suitable for preemptible VMs?
A. A scalable in-memory caching system.
B. The organization’s public-facing website.
C. A distributed, eventually consistent NoSQL database cluster with sufficient quorum.
D. A GPU-accelerated video rendering platform that retrieves and stores videos in a storage bucket.

A
Explanation
Key points are underlined.
You need to reduce the cost of virtual machines (VM) for your organization. After reviewing different options, you decide to leverage preemptible VM instances.
Which application is suitable for preemptible VMs?
Preemptible VMs are best suited for fault-tolerant, non-critical applications due to their temporary nature.
A. A scalable in-memory caching system. (Non-critical workload)
B. The organization’s public-facing website. (Critical workload)
C. A distributed, eventually consistent NoSQL database cluster with sufficient quorum. (Critical workload)
D. A GPU-accelerated video rendering platform that retrieves and stores videos in a storage bucket.
(Attaching GPU with preemptible VM will increase cost, and in this question the purpose of opting for preemptible VM is reducing cost.)
