Question 97

A company uses an external identity provider to allow federation into different IAM accounts. A security engineer for the company needs to identify the federated user that terminated a production Amazon EC2 instance a week ago.

What is the FASTEST way for the security engineer to identify the federated user?

Options:

Review the IAM CloudTrail event history logs in an Amazon S3 bucket and look for the Terminatelnstances event to identify the federated user from the role session name.

Filter the IAM CloudTrail event history for the Terminatelnstances event and identify the assumed IAM role. Review the AssumeRoleWithSAML event call in CloudTrail to identify the corresponding username.

Search the IAM CloudTrail logs for the Terminatelnstances event and note the event time. Review the IAM Access Advisor tab for all federated roles. The last accessed time should match the time when the instance was terminated.

Use Amazon Athena to run a SQL query on the IAM CloudTrail logs stored in an Amazon S3 bucket and filter on the Terminatelnstances event. Identify the corresponding role and run another query to filter the AssumeRoleWithWebldentity event for the user name.

Question 99

A security engineer configures Amazon S3 Cross-Region Replication (CRR) for all objects that are in an S3 bucket in the us-east-1. Region Some objects in this S3 bucket use server-side encryption with AWS KMS keys (SSE-KMS) for encryption at test. The security engineer creates a destination S3 bucket in the us-west-2 Region. The destination S3 bucket is in the same AWS account as the source S3 bucket.

The security engineer also creates a customer managed key in us-west-2 to encrypt objects at rest in the destination S3 bucket. The replication configuration is set to use the key in us-west-2 to encrypt objects in the destination S3 bucket. The security engineer has provided the S3 replication configuration with an IAM role to perform the replication in Amazon S3.

After a day, the security engineer notices that no encrypted objects from the source S3 bucket are replicated to the destination S3 bucket. However, all the unencrypted objects are replicated.

Which combination of steps should the security engineer take to remediate this issue? (Select THREE.)

Options:

Change the replication configuration to use the key in us-east-1 to encrypt the objects that are in the destination S3 bucket.

Grant the IAM role the kms. Encrypt permission for the key in us-east-1 that encrypts source objects.

Grant the IAM role the s3 GetObjectVersionForReplication permission for objects that are in the source S3 bucket.

Grant the IAM role the kms. Decrypt permission for the key in us-east-1 that encrypts source objects.

Change the key policy of the key in us-east-1 to grant the kms. Decrypt permission to the security engineer's IAM account.

Grant the IAM role the kms Encrypt permission for the key in us-west-2 that encrypts objects that are in the destination S3 bucket.
