Amazon SAP-C02 Exam - Topic 7 Question 12 Discussion

Actual exam question for Amazon's SAP-C02 exam

Question #: 12
Topic #: 7

A financial services company loaded millions of historical stock trades into an Amazon DynamoDB table. The table uses on-demand capacity mode. Once each day at midnight, a few million new records are loaded into the table. Application read activity against the table happens in bursts throughout the day. and a limited set of keys are repeatedly looked up. The company needs to reduce costs associated with DynamoDB.

Which strategy should a solutions architect recommend to meet this requirement?

ADeploy an Amazon ElastiCache cluster in front of the DynamoDB table.

BDeploy DynamoDB Accelerator (DAX). Configure DynamoDB auto scaling. Purchase Savings Plans in Cost Explorer

CUse provisioned capacity mode. Purchase Savings Plans in Cost Explorer.

DDeploy DynamoDB Accelerator (DAX). Use provisioned capacity mode. Configure DynamoDB auto scaling.

Show Suggested Answer

Suggested Answer: A

it will use the ALB to handle the unpredictable bursts of traffic and route it to the SQS queue. The SQS queue will act as a buffer to store incoming data temporarily and the container running in Amazon ECS with the Fargate launch type will process messages in the queue. This approach will ensure that all data is processed and prevent data loss.

Not sure about DAX, it adds complexity.

Provisioned capacity is a solid choice here.

Surprised they didn’t mention caching first!

I think option C makes more sense for cost savings.

DAX can really speed up reads!

I feel like combining DAX with provisioned capacity might be the right approach, but I’m not clear on how Savings Plans fit into the overall strategy.

I practiced a similar question where switching to provisioned capacity saved costs, but I’m not entirely sure if we need auto scaling with that.

I think DAX could be a good choice for caching those repeated lookups, but I’m a bit confused about whether we should stick with on-demand or switch to provisioned capacity.

I remember that using ElastiCache can help reduce read costs, but I'm not sure if it's the best option here since we have a lot of writes too.

Hmm, this looks straightforward. I think the output will be 2 since the increment function increments the value by 1.

Honestly, I'm not totally sure. I thought merging was different from adding a new endpoint, so maybe A and C?

Okay, let's see. The workstation is sluggish for one user but not others, and the admin has validated it's working normally. I'm leaning towards B or D.

Communicating IT risks to the business is also really important. They need to be aware of the risks to make informed decisions.

I'm really unsure here; isn't a Cartesian product basically what you get from combining two sets? I keep mixing up the concepts of joins.

Word cloud sounds familiar, but I remember it's more about visualizing keywords rather than focusing on specific short phrases.

D looks like the full package - DAX, provisioned capacity, and auto-scaling. It's like a Swiss Army knife for this DynamoDB problem.

C is tempting, but I don't think provisioned capacity is the answer. Gotta take advantage of those DynamoDB features to optimize performance and cost.

I'm going with B. DAX and auto-scaling sounds like the way to go here. Beats having to manually provision capacity and worry about those pesky Savings Plans.

I'm leaning towards B as well. DAX and auto-scaling seem like a good combination to reduce costs.

I agree, B does seem like the best option. DAX can definitely help with reducing costs and auto-scaling is convenient.

Wait, so we need to reduce costs, but they're loading in millions of records daily? That's like trying to save money on your electricity bill while running a Bitcoin mining operation out of your basement!
