Exam Q&A

Q1: A company is investigating an increase in its AWS monthly bill. The company discovers that bad actors compromised some Amazon EC2 instances and served webpages for a large email phishing campaign. A security engineer must implement a solution to monitor for cost increases in the future to help detect malicious activity. Which solution will offer the company the EARLIEST detection of cost increases?

A: Create an Amazon EventBridge rule that invokes an AWS Lambda function hourly. Program the Lambda function to download an AWS usage report from AWS Data Exports about usage of all services. Program the Lambda function to analyze the report and to send a notification when anomalies are detected.

B: Create a cost monitor in AWS Cost Anomaly Detection. Configure an individual alert to notify an Amazon Simple Notification Service (Amazon SNS) topic when the percentage above the expected cost exceeds a threshold.

C: Review AWS Cost Explorer daily to detect anomalies in cost from prior months Review the usage of any services that experience a significant cost increase from prior months.

D: Capture VPC flow logs from the VPC where the EC2 instances run. Use a third-party network analysis tool to analyze the flow logs and to detect anomalies in network traffic that might increase cost.

Correct Answer: B

Q2: A company uses HTTP Live Streaming (HL'S) to stream live video content to paying subscribers by using Amazon CloudFront. HLS splits the video content into chunks so that the user can request the right chunk based on different conditions. Because the video events last for several hours, the total video is made up of thousands of chunks. The origin URL is not disclosed, and every user is forced to access the CloudFront URL. The company has a web application that authenticates the paying users against an internal repository and a CloudFront key pair that is already issued. What is the simplest and MOST effective way to protect the content?

A: Develop the application to use the CloudFront key pair to create signed URLs that users will use to access the content.

B: Develop the application to use the CloudFront key pair to set the signed cookies that users will use to access the content.

C: Develop the application to issue a security token that Lambda@Edge will receive to authenticate and authorize access to the content

D: Keep the CloudFront URL encrypted inside the application, and use AWS KMS to resolve the URL on-the-fly after the user is authenticated.

Correct Answer: B

Q3: A company is running an application on Amazon EC2 instances in an Auto Scaling group. The application stores logs locally. A security engineer noticed that logs were lost after a scale-in event. The security engineer needs to recommend a solution to ensure the durability and availability of log data All logs must be kept for a minimum of 1 year for auditing purposes. What should the security engineer recommend?

A: Within the Auto Scaling lifecycle, add a hook to create and attach an Amazon Elastic Block Store (Amazon EBS) log volume each time an EC2 instance is created. When the instance is terminated, the EBS volume can be reattached to another instance for log review.

B: Create an Amazon Elastic File System (Amazon EFS) file system and add a command in the user data section of the Auto Scaling launch template to mount the EFS file system during EC2 instance creation. Configure a process on the instance to copy the logs once a day from an instance Amazon Elastic Block Store (Amazon EBS) volume to a directory in the EFS file system.

C: Add an Amazon CloudWatch agent into the AMI used in the Auto Scaling group. Configure the CloudWatch agent to send the logs to Amazon CloudWatch Logs for review,

D: Within the Auto Scaling lifecycle, add a lifecycle hook at the terminating state transition and alert the engineering team by using a lifecycle notification to Amazon Simple Notification Service (Amazon SNS). Configure the hook to remain in the Terminating:Wait state for 1 hour to allow manual review of the security logs prior to instance termination.

Correct Answer: C

Q4: A company wants to receive automated email notifications when AWS access keys from developer AWS accounts are detected on code repository sites. Which solution will provide the required email notifications?

A: Create an Amazon EventBridge rule to send Amazon Simple Notification Service (Amazon SNS) email notifications for Amazon GuardDuty UnauthorizedAccesslAMUser/lnstanceCredentialExfiltration OutsideAWS findings.

B: Change the AWS account contact information for the Operations type to a separate email address. Periodically poll this email address for notifications.

C: Create an Amazon EventBridge rule that reacts to AWS Health events that have a value of Risk for the service category Configure email notifications by using Amazon Simple Notification Service (Amazon SNS).

D: Implement new anomaly detection software. Ingest AWS CloudTrail logs. Configure monitoring for ConsoleLogin events in the AWS Management Console. Configure email notifications from the anomaly detection software.

Correct Answer: A
