An orgAMzation has 10000 employees. The orgAMzation wants to give restricted AWS access to each employee. How can the orgAMzation achieve this?
Correct Answer:D
Identity federation enables users from an existing directory to access resources within your AWS account,
making it easier to manage your users by maintaining their identities in a single place. In this case, the federated user is the only solution since AWS does not allow creating more than 5000 IAM users. Reference: http://docs.aws.amazon.com/IAM/latest/UserGuide/LimitationsOnEntities.html
A user has setup an application on EC2 which uses the IAM user access key and secret access key to make secure calls to S3. The user wants to temporarily stop the access to S3 for that IAM user. What should the root owner do?
Correct Answer:C
If the user wants to temporarily stop the access to S3 the best solution is to disable the keys. Deleting the user will result in a loss of all the credentials and the app will not be useful in the future. If the user stops the instance IAM users can still access S3. The change of the key does not help either as they are still active. The best possible solution is to disable the keys.
