AWS Certified Security - Specialty Questions and Answers

Question 81

A company has a legacy application that runs on a single Amazon EC2 instance. A security audit shows that the application has been using an IAM access key within its code to access an Amazon S3 bucket that is named DOC-EXAMPLE-BUCKET1 in the same AWS account. This access key pair has the s3:GetObject permission to all objects in only this S3 bucket. The company takes the application offline because the application is not compliant with the company’s security policies for accessing other AWS resources from Amazon EC2.

A security engineer validates that AWS CloudTrail is turned on in all AWS Regions. CloudTrail is sending logs to an S3 bucket that is named DOC-EXAMPLE-BUCKET2. This S3 bucket is in the same AWS account as DOC-EXAMPLE-BUCKET1. However, CloudTrail has not been configured to send logs to Amazon CloudWatch Logs.

The company wants to know if any objects in DOC-EXAMPLE-BUCKET1 were accessed with the IAM access key in the past 60 days. If any objects were accessed, the company wants to know if any of the objects that are text files (.txt extension) contained personally identifiable information (PII).

Which combination of steps should the security engineer take to gather this information? (Choose two.)

Options:

Configure Amazon Macie to identify any objects in DOC-EXAMPLE-BUCKET1 that contain PII and that were available to the access key.

Use Amazon CloudWatch Logs Insights to identify any objects in DOC-EXAMPLE-BUCKET1 that contain PII and that were available to the access key.

Use Amazon OpenSearch Service (Amazon Elasticsearch Service) to query the CloudTrail logs in DOC-EXAMPLE-BUCKET2 for API calls that used the access key to access an object that contained PII.

Use Amazon Athena to query the CloudTrail logs in DOC-EXAMPLE-BUCKET2 for any API calls that used the access key to access an object that contained PII.

Use AWS Identity and Access Management Access Analyzer to identify any API calls that used the access key to access objects that contained PII in DOC-EXAMPLE-BUCKET1.

Question 82

A company runs an online game on AWS. When players sign up for the game, their username and password credentials are stored in an Amazon Aurora database.

The number of users has grown to hundreds of thousands of players. The number of requests for password resets and login assistance has become a burden for the company’s customer service team.

The company needs to implement a solution to give players another way to log in to the game. The solution must remove the burden of password resets and login assistance while securely protecting each player's credentials.

Which solution will meet these requirements?

Options:

When a new player signs up, use an AWS Lambda function to automatically create an 1AM access key and a secret access key. Program the Lambda function to store the credentials on the player's device. Create 1AM keys for existing players.

B Migrate the player credentials from the Aurora database to AWS Secrets Manager. When a new player signs up. create a key-value pair in Secrets Manager for the player's user ID and password.

Configure Amazon Cognito user pools to federate access to the game with third-party identity providers (IdPs), such as social IdPs Migrate the game's authentication mechanism to Cognito.

Instead of using usernames and passwords for authentication, issue API keys to new and existing players. Create an Amazon API Gateway API to give the game client access to the game's functionality.

Question 83

An AWS Lambda function was misused to alter data, and a security engineer must identify who invoked the function and what output was produced. The engineer cannot find any logs create^ by the Lambda function in Amazon CloudWatch Logs.

Which of the following explains why the logs are not available?

Options:

The execution role for the Lambda function did not grant permissions to write log data to CloudWatch Logs.

The Lambda function was invoked by using Amazon API Gateway, so the logs are not stored in CloudWatch Logs.

The execution role for the Lambda function did not grant permissions to write to the Amazon S3 bucket where CloudWatch Logs stores the logs.

The version of the Lambda function that was invoked was not current.

Question 84

A company is storing data in Amazon S3 Glacier. A security engineer implemented a new vault lock policy for 10 TB of data and called the initiate-vault-lock operation 12 hours ago. The audit team identified a typo in the policy that is allowing unintended access to the vault.

What is the MOST cost-effective way to correct this error?

Options:

Call the abort-vault-lock operation. Update the policy. Call the initiate-vault-lock operation again.

Copy the vault data to a new S3 bucket. Delete the vault. Create a new vault with the data.

Update the policy to keep the vault lock in place

Update the policy. Call the initiate-vault-lock operation again to apply the new policy.
