Exam AWS Certified Solutions Architect - Professional topic 1 question 414 discussion

AEF B: not feasible. C: Not everything is applicable to RI. E.g. S3 does not have RI. D: If they chose a very big instance, the bill could still be big.

AEF for sure

AEF https://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/custom-tags.html

It's A E F

Based on comments

A. Implement an IAM policy that requires users to specify a ג€˜workloadג€™ tag for cost allocation when launching Amazon EC2 instances. E. Define ג€˜workloadג€™ as a cost allocation tag in the AWS Billing and Cost Management console. F. Set up AWS Budgets to alert and notify when a given workload is expected to exceed a defined cost.

AEF is my answer

AEF ---

It's A E F

ACF Key word is "predictable spend" A -> will not be able to run a resource that is not taged "Effect": "Deny", "Action": "whatever:youchoose", "Resource": "*", "Condition": { "ForAllValues:StringNotEquals": { "aws:TagKeys": "workload" }} B - impossible per user C -> obvious - it gives you predictable cost D -> impossible E -> it only enables TAGs in Cost&Usage F -> obvious (Filters:Dimension in Budget) - then you can set up alerts based on workloads (tags).

I'll go with A,E,F

only AEF can be answer

I think answer should be CEF. A. Not because - IAM Policy can restrict access to existing EC2 based on tag but cannot enforce to create tag while creating EC2 instance. B. Not Because - that can be done through IAM policy. no need to got AWS support. C. Because - There are many other services also needs to be in consideration to reduce cost but reserved instances can also contribute to reduce cost. D. Not possible.

AEF B- Not feasible C- RI is for years not monthly D- Requirement is to put check on monthly budget not on number of instances. 1 big instance = big budget

AEF for sure

AEF are correct answers.

I think AEF is correct, as long as EC2 is the main service being used. At first I thought what's wrong with BCD. B: You can contact AWS Support to decrease limit. C: Reserved Instances is a good way to lower your cost. Of course if some may say that the company may not use EC2 for long time, but AEF are based on EC2 is the main service the company is using. D: same as B. But think it again, the key of the question is "achieve a cost that is as close as possible to the target amount". AEF can alert Solutions Architect and he/she can adjust the resources being used to control cost.
