Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 196 discussion

i'm going with BE. A not correct with EC2 instances to mantain. C is not correct because we cannot host webapplication on S3 (only static contents) D too much effort for Redshift

A. EC2 on-demand instances don't make sense to accept timesheet entries B. ECS can be done but they want to minimise operational overhead where option C sounds better/simple C. Sounds simple enough to use s3. I choose this. D. I already chose s3 so this doesn't apply + redshift seems overkill E.This goes with Option C So answer C and E

C is best for frontend/API E is best for storage + reports

C is better option than B bcz it is managed/serverless than ECS (without mentioning Fargate)

B is not right option as ECS management overhead unless specified with Fargate Launch type.

Key parameter is " with most of the submissions occurring on Friday." hence BE is the right answer

E is apparently. I would go for B rather than C. Even serverless lambda is best suited for minimizing operational overhead; however the point is "mobile devices"; the mobile application is the frontend => "Deploy the application front end to an Amazon S3 bucket served by Amazon CloudFront" from C does not make sense.

CE-CE-CE

i'm going with BE.

High availability = multiple availability zones (clue in the answer, B) Cannot be C as it's a web application so cannot be on S3. Lambda not suitable either because Lambdas only run in a single chosen region of deployment.

Option A (EC2 On-Demand Instances with Auto Scaling) requires managing and scaling EC2 instances, which adds operational overhead compared to a serverless approach. Option B (Amazon ECS with Service Auto Scaling) also requires managing and scaling container instances, which adds operational overhead compared to a serverless approach. Option D (Amazon Redshift) is a data warehousing solution better suited for large-scale analytics workloads, which may be overkill for the given requirements and introduce unnecessary complexity and cost. By choosing the combination of options C and E, the solutions architect can implement a highly available, scalable, and cost-effective solution with minimal operational overhead, leveraging the benefits of serverless computing, object storage, and managed analytics services.

Options A and B involve managing EC2 instances or containers, which would require more operational effort than a fully serverless solution with C and E.

It's B & E, the question says that timeshares will need ro be submitted. Therefore making it dynamic. Selecting option C to use S3 to host webapp can't work because S3 can host static sites.

C is Incorrect

Voting for BE

C is not correct. We need Lambda, not Lambda Proxy. BTW, APIGW + Lambda for the unknown load, in this case we knew that high load on Friday

Answer is B and E. We already know which on friday a lot of people will submit timesheet, so scheduled autoscaling is perfect. Finally S3 + Athena are enough. No need of Redshift database to run report.
