Amazon SAP-C02 Exam - Topic 7 Question 38 Discussion

Actual exam question for Amazon's SAP-C02 exam

Question #: 38
Topic #: 7

An events company runs a ticketing platform on AWS. The company's customers configure and schedule their events on the platform The events result in large increases of traffic to the platform The company knows the date and time of each customer's events

The company runs the platform on an Amazon Elastic Container Service (Amazon ECS) cluster The ECS cluster consists of Amazon EC2 On-Demand Instances that are in an Auto Scaling group. The Auto Scaling group uses a predictive scaling policy

The ECS cluster makes frequent requests to an Amazon S3 bucket to download ticket assets The ECS cluster and the S3 bucket are in the same AWS Region and the same AWS account Traffic between the ECS cluster and the S3 bucket flows across a NAT gateway

The company needs to optimize the cost of the platform without decreasing the platform's availability

Which combination of steps will meet these requirements? (Select TWO)

ACreate a gateway VPC endpoint for the S3 bucket

BAdd another ECS capacity provider that uses an Auto Scaling group of Spot Instances Configure the new capacity provider strategy to have the same weight as the existing capacity provider strategy

CCreate On-Demand Capacity Reservations for the applicable instance type for the time period of the scheduled scaling policies

DEnable S3 Transfer Acceleration on the S3 bucket

EReplace the predictive scaling policy with scheduled scaling policies for the scheduled events

Show Suggested Answer

Suggested Answer: A, B

Gateway VPC Endpoint for S3:

Create a gateway VPC endpoint for Amazon S3 in your VPC. This allows instances in your VPC to communicate with Amazon S3 without going through the internet, reducing data transfer costs and improving security.

Add Spot Instances to ECS Cluster:

Add another ECS capacity provider that uses an Auto Scaling group of Spot Instances. Configure this new capacity provider to share the load with the existing On-Demand Instances by setting an appropriate weight in the capacity provider strategy. Spot Instances offer significant cost savings compared to On-Demand Instances.

Configure Capacity Provider Strategy:

Adjust the ECS service's capacity provider strategy to utilize both On-Demand and Spot Instances effectively. This ensures a balanced distribution of tasks across both instance types, optimizing cost while maintaining availability.

By implementing a gateway VPC endpoint for S3 and incorporating Spot Instances into the ECS cluster, the company can significantly reduce operational costs without compromising on the availability or performance of the platform.

Wait, does enabling S3 Transfer Acceleration really help with costs?

Scheduled scaling policies seem like a better fit for known event times.

I’m not sure about the Spot Instances, they can be unreliable during peak times.

A gateway VPC endpoint for S3 would save costs on NAT gateway usage.

I’m a bit confused about the On-Demand Capacity Reservations. I thought they were more for ensuring availability rather than cost optimization. Would that really help here?

I feel like enabling S3 Transfer Acceleration might not be necessary since they’re in the same region. I think I’d lean towards using scheduled scaling policies instead.

I remember practicing a question about using Spot Instances for cost optimization. Adding another ECS capacity provider with Spot Instances sounds like a good idea, but I’m not clear on how it impacts availability.

I think creating a gateway VPC endpoint for the S3 bucket could really help reduce costs by avoiding NAT gateway charges, but I'm not entirely sure if it's the best option.

Replacing the predictive scaling policy with scheduled scaling policies seems like a good way to align the infrastructure with the known event schedules. I'll focus on that as a key strategy.

Enabling S3 Transfer Acceleration could improve performance, but I'm not sure if that would directly impact the cost. Might be worth considering.

I'm a bit confused by the On-Demand Capacity Reservations option. I'll need to research that more to understand how it could optimize costs.

Hmm, creating a gateway VPC endpoint for S3 and adding Spot Instances to the capacity provider strategy could both help reduce costs. I'll have to think through the trade-offs.

Hmm, I'm a bit confused on this one. I know we need multiple search heads for high availability, but I'm not sure of the exact recommended minimum. I'll have to think this through carefully.

I'm just picturing the events team frantically trying to figure out the optimal AWS settings while the customers are hammering the platform. 'Quick, someone call the AWS cost optimization hotline!'

D is an interesting one. S3 Transfer Acceleration could help with the download speeds, but I'm not sure how much that would impact the overall cost. Hmm, tough choice here.

A and E seem like the way to go. The gateway VPC endpoint will bypass the NAT gateway, and the scheduled scaling policies will be more targeted to the event schedules.
