Question 16

A gaming company is developing a new mobile game and decides to store the data for each user in Amazon DynamoDB. To make the registration process as easy as possible, users can log in with their existing Facebook or Amazon accounts. The company expects more than 10,000 users.

How should a database specialist implement access control with the LEAST operational effort?

Options:

Use web identity federation on the mobile app and AWS STS with an attached IAM role to get temporary credentials to access DynamoDB.

Use web identity federation on the mobile app and create individual IAM users with credentials to access DynamoDB.

Use a self-developed user management system on the mobile app that lets users access the data from DynamoDB through an API.

Use a single IAM user on the mobile app to access DynamoDB.

My experience with Cramkey was great! I was surprised to see that many of the questions in my exam appeared in the Cramkey dumps.

Yes, In fact, I got a score of above 85%. And I attribute a lot of my success to Cramkey's dumps.

Hey I passed my exam. The world needs to know about it. I have never seen real exam questions on any other exam preparation resource like I saw on Cramkey Dumps.

That's true. Cramkey Dumps are simply the best when it comes to preparing for the certification exam. They have all the key information you need and the questions are very similar to what you'll see on the actual exam.

Ayesha

They are study materials that are designed to help students prepare for exams and certification tests. They are basically a collection of questions and answers that are likely to appear on the test.
