Amazon SAP-C02 Exam - Topic 3 Question 55 Discussion

Actual exam question for Amazon's SAP-C02 exam

Question #: 55
Topic #: 3

A company is deploying a distributed in-memory database on a fleet of Amazon EC2 instances. The fleet consists of a primary node and eight worker nodes. The primary node is responsible for monitoring cluster health, accepting user requests, distributing user requests to worker nodes, and sending an aggregate response back to a client. Worker nodes communicate with each other to replicate data partitions.

The company requires the lowest possible networking latency to achieve maximum performance.

Which solution will meet these requirements?

ALaunch memory optimized EC2 instances in a partition placement group.

BLaunch compute optimized EC2 instances in a partition placement group.

CLaunch memory optimized EC2 instances in a cluster placement group

DLaunch compute optimized EC2 instances in a spread placement group.

I think compute optimized might work too, but not as well as memory optimized.

I recall that compute optimized instances are generally better for processing power, but for an in-memory database, memory optimized instances might be more suitable.

I’m a bit confused about the difference between partition and cluster placement groups. I feel like cluster might be the way to go for this, but I need to double-check.

I think we practiced a similar question where cluster placement groups were mentioned. They might be the right choice for minimizing latency, especially with memory optimized instances.

I remember that partition placement groups are good for reducing latency, but I'm not sure if memory or compute optimized instances are better for this scenario.

I feel pretty confident about this one. The question states the company wants maximum performance, so memory-optimized instances in a partition placement group seem like the obvious choice to me.

Okay, I've got a strategy here. Since the company wants the lowest possible networking latency, I'm thinking a partition placement group is the way to go. That should ensure the nodes are physically isolated from each other, reducing the chances of network interference.

Hmm, I'm a bit confused by the different placement group options. I'll need to review the differences between partition, cluster, and spread placement groups to figure out which one is best for this scenario.

This looks like a classic networking optimization question. I think the key is to focus on minimizing latency between the nodes, so a placement group is likely the way to go.
