specific wording on the requirements

[cdt78]

For this question:

A telecommunications company plans to have a public announcement for a new phone offering. It is expected that millions of people will access their website to get the new offer. Their company’s e-commerce platform is running on an Auto Scaling group of On-Demand EC2 instances deployed across multiple Availability Zones. For the database tier, the platform is using an Amazon RDS database in a Multi-AZ deployments configuration. Their e-commerce site performs a high number of small reads and writes per second to handle customer transactions and relies on an eventual consistency model. The Operations team identified that there is read contention on RDS MySQL database after conducting a series of performance tests.

Which combination of options should you implement to provide a fast, cost-efficient, and scalable solution? (Select TWO.)

Fast can be interpreted in 2 ways:

• fast, as in performant
• fast, as in easy to be implemented, fast to be delivered as ready to be used

With ElastiCache for sure it will not be fast to implement 🙂 as it will require app code level changes.

I would re-word to something more specific so the test taker can understand what is the specific requirement here.

Hi cdt78,

Thank you for sharing your feedback on this question.

Generally, “fast” in the context of the question means that it is performant.

The “fast” as in “fast to implement” is usually explicitly specified on the question scenario. For example, wordings like “quickly implemented”, “a solution that can be implemented fast”, or when the scenario states that “no code changes” or “minimal code changes” which could be interpreted as fast implementation.

Please note that there are questions in the actual AWS exam that are difficult, tricky, and ambiguous. This is a professional level exam question and AWS assumes you have a deep understanding or working knowledge depending on the given scenario. We try to mimic the level of difficulty from actual AWS exams and some questions do not explicitly show the obvious keywords and you have to assume some given best practices.

Let us know if you need further assistance. The Tutorials Dojo team is dedicated to helping you pass your AWS exam!
