Discuss Amazon PAS-C01 Exam Topic 10 Question 14

A company is planning to migrate its on-premises SAP ERP Central Component (SAP ECC) system on SAP HANA to AWS Each month the system experiences two peaks in usage. The first peak is on the 21st day of the month when the company runs payroll. The second peak is on the last day of the month when the company processes and exports credit data Both peak workloads are of high importance and cannot be rescheduled

The current SAP ECC system has six application servers an of a similar size. During normal operation outside of peak usage four application servers would suffice

Which purchasing option will meet the company's requirements MOST cost-effectively on AWS?

AFour Reserved Instances and two Spot Instances

BSix On-Demand Instances

CSix Reserved Instances

DFour Reserved Instances and two On-Demand Instances

Suggested Answer: C

VPC endpoints to ensure that traffic to and from the CloudWatch and EC2 services stays within the VPC. Additionally, an IAM policy is created to grant access to only the necessary actions, such as DescribeInstances and GetMetricStatistics, for all EC2 resources. This approach will provide secure monitoring of the SAP system while maximizing security and ensuring support from both SAP and AWS.

Six Reserved Instances sounds like overkill for normal operations.

Bettina 12 months ago

Surprised they can manage with just four Reserved Instances during peaks.

Shawnda 12 months ago

Not sure if Spot Instances are reliable enough for payroll.

Garry 1 year ago

I think four Reserved Instances and two Spot Instances is the best mix!

Antonette 1 year ago

Six On-Demand Instances would be too pricey for regular use.

Ty 1 year ago

I feel like six On-Demand Instances would be too expensive, but I can't shake the feeling that we might need all six servers during peak times. This is tricky!

I’m leaning towards option D, but I’m a bit uncertain. I remember that having some On-Demand instances can help during peak times, but I’m not sure if four Reserved is enough.

Tori 1 year ago

I think we practiced a similar question where we had to balance between Reserved and On-Demand Instances. I feel like the peaks might make On-Demand a better choice, but I can't recall the exact details.

I remember we discussed how Reserved Instances are usually more cost-effective for steady workloads, but I'm not sure if they fit perfectly here with the peaks.

Okay, I've got this. The two ways to assign the migrated female customers to the segment are B and C - running the index reindex command and clicking the Refresh Segment Data button.

Okay, the new CDB_-views are a good clue. I think I've got a handle on the main differences now, so I'll start selecting the answers.

I don't know, guys. You're all overthinking this. Why not just use a bunch of hamsters on wheels to power the system? I heard they're really energy-efficient.

Dong 1 year ago

Option C seems a bit too conservative to me. Why pay for Reserved Instances when you only need four servers most of the time? I think a mix of Reserved and on-demand is the way to go.

Rochell 1 year ago

Hold on, is this a trick question? What if we go with Option B and just run everything on-demand? I mean, it's not like we're talking about a massive scale here, right? Who cares about cost-optimization, let's just keep it simple!

Let's not overlook cost-optimization, we need to find the most cost-effective solution for our peak workloads.

Chandra 1 year ago

I think we should consider the peak workloads and go for a mix of Reserved and On-Demand Instances to save costs.

Option B might work for simplicity, but it might end up costing us more in the long run.

Leeann 1 year ago

I'm leaning towards Option A. Spot Instances can provide significant cost savings for the peak workloads, and the Reserved Instances will cover the base usage.

Arlette 1 year ago

↳ replying to Leeann

It seems like a good balance between cost-effectiveness and meeting the peak workload demands.

Pete 1 year ago

↳ replying to Leeann

I agree, having Reserved Instances for the base usage is a smart move.

↳ replying to Leeann

Option A sounds like a good choice. Spot Instances can really help with cost savings.

Cecily 1 year ago

Option D seems like the most cost-effective choice. The company can reserve instances for the baseline usage and use on-demand instances to handle the peak workloads, which makes sense.

Sherell 1 year ago

↳ replying to Cecily

It's important to balance cost-effectiveness with performance, and option D seems to achieve that.

Using reserved instances for baseline usage and on-demand instances for peak workloads is a smart strategy.

Rosalyn 1 year ago

I agree, option D seems like a good choice. It provides the flexibility needed for the peak workloads.

Celeste 2 years ago

But wouldn't it be more cost-effective to have a mix of Reserved and Spot Instances for the peak workloads?

Noel 2 years ago

I disagree, I believe the answer is A) Four Reserved Instances and two Spot Instances.

Celeste 2 years ago

I think the answer is C) Six Reserved Instances.
