Question # 2

 security engineer is troubleshooting an AWS Lambda function that isnamedMyLambdaFunction. The function is encountering an error when the functionattempts to read the objects in an Amazon S3 bucket that is namedDOC-EXAMPLEBUCKET. The S3 bucket has the following bucket policy:{"Effect": "Allow","Principal": { "Service": "lambda.amazonaws.com" },"Action": "s3:GetObject","Resource": "arn:aws:s3:::DOC-EXAMPLE-BUCKET","Condition": {"ArnLike": {"aws:SourceArn": "arn:aws:lambda:::function:MyLambdaFunction"}}}Which change should the security engineer make to the policy to ensure that the Lambdafunction can read the bucket objects?

A. Remove the Condition element. Change the Principal element to the following:{ "AWS":"arn:aws:lambda:::function:MyLambdaFunction" }
B. Change the Action element to the following:["s3:GetObject*", "s3:GetBucket*"]
C. Change the Resource element to"arn:aws:s3:::DOC-EXAMPLE-BUCKET/*".

Question # 3

A company is operating an open-source software platform that is internet facing. Thelegacy software platform no longer receives security updates. The software platformoperates using Amazon Route 53 weighted load balancing to send traffic to two AmazonEC2 instances that connect to an Amazon RDS cluster. A recent report suggests thissoftware platform is vulnerable to SQL injection attacks, with samples of attacks provided.The company’s security engineer must secure this system against SQL injection attackswithin 24 hours. The security engineer’s solution must involve the least amount of effortand maintain normal operations during implementation.What should the security engineer do to meet these requirements?

A. Create an Application Load Balancer with the existing EC2 instances as a target group.Create an AWS WAF web ACL containing rules that protect the application from this attack,then apply it to the ALB. Test to ensure the vulnerability has been mitigated, then redirectthe Route 53 records to point to the ALB. Update security groups on the EC2 instances toprevent direct access from the internet.
B. Create an Amazon CloudFront distribution specifying one EC2 instance as an origin.Create an AWS WAF web ACL containing rules that protect the application from this attack,then apply it to the distribution. Test to ensure the vulnerability has been mitigated, thenredirect the Route 53 records to point to CloudFront.
C. Obtain the latest source code for the platform and make the necessary updates. Testthe updated code to ensure that the vulnerability has been mitigated, then deploy thepatched version of the platform to the EC2 instances.
D. Update the security group that is attached to the EC2 instances, removing access fromthe internet to the TCP port used by the SQL database. Create an AWS WAF web ACLcontaining rules that protect the application from this attack, then apply it to the EC2instances. Test to ensure the vulnerability has been mitigated, then restore the securitygroup to the original setting.

Question # 4

A company has enabled AWS Config for its organization in AWS Organizations. Thecompany has deployed hundreds of Amazon S3 buckets across the organization. Asecurity engineer needs to identify any S3 buckets that are not encrypted with AWS KeyManagement Service (AWS KMS). The security engineer also must prevent objects thatare not encrypted with AWS KMS from being uploaded to the S3 buckets.Which solution will meet these requirements?

A. Use thes3-default-encryption-kmsAWS Config managed rule to identify unencrypted S3buckets. Create an SCP to allow thes3:PutObjectaction only when the object is encryptedwith AWS KMS.
B. Use thes3-default-encryption-kmsAWS Config managed rule to identify unencrypted S3buckets. Create bucket policies for each S3 bucket to deny thes3:PutObjectaction onlywhen the object has server-side encryption with S3 managed keys (SSE-S3).
C. Use thes3-bucket-ssl-requests-onlyAWS Config managed rule to identify unencryptedS3 buckets. Create an SCP to allow thes3:PutObjectaction only when the object isencrypted with AWS KMS
D. Use thes3-bucket-ssl-requests-onlyAWS Config managed rule to identify unencryptedS3 buckets. Create bucket policies for each S3 bucket to allow thes3:PutObjectaction onlywhen the object is encrypted with AWS KMS

Question # 7

A company’s security team needs to receive a notification whenever an AWS access keyhas not been rotated in 90 or more days. A security engineer must develop a solution thatprovides these notifications automatically.Which solution will meet these requirements with the LEAST amount of effort?

A. Deploy an AWS Config managed rule to run on a periodic basis of 24 hours. Select theaccess-keys-rotated managed rule, and set the maxAccessKeyAge parameter to 90 days.Create an Amazon EventBridge rule with an event pattern that matches the compliancetype of NON_COMPLIANT from AWS Config for the managed rule. Configure EventBridgeto send an Amazon SNS notification to the security team.
B. Create a script to export a .csv file from the AWS Trusted Advisor check for IAM accesskey rotation. Load the script into an AWS Lambda function that will upload the .csv file toan Amazon S3 bucket. Create an Amazon Athena table query that runs when the .csv fileis uploaded to the S3 bucket. Publish the results for any keys older than 90 days by usingan invocation of an Amazon SNS notification to the security team.
C. Create a script to download the IAM credentials report on a periodic basis. Load thescript into an AWS Lambda function that will run on a schedule through AmazonEventBridge. Configure the Lambda script to load the report into memory and to filter thereport for records in which the key was last rotated at least 90 days ago. If any records aredetected, send an Amazon SNS notification to the security team
D. Create an AWS Lambda function that queries the IAM API to list all the users. Iteratethrough the users by using the ListAccessKeys operation. Verify that the value in theCreateDate field is not at least 90 days old. Send an SNS notification to the security team ifthe value is at least 90 days old. Create an EventBridge rule to schedule the Lambdafunction to run each day.

Question # 10

A company hosts a web application on an Apache web server. The application runs onAmazon EC2 instances that are in an Auto Scaling group. The company configured theEC2 instances to send the Apache web server logs to an Amazon CloudWatch Logs groupthat the company has configured to expire after 1 year.Recently, the company discovered in the Apache web server logs that a specific IP addressis sending suspicious requests to the web application. A security engineer wants to analyzethe past week of Apache web server logs to determine how many requests that the IPaddress sent and the corresponding URLs that the IP address requested.What should the security engineer do to meet these requirements with the LEAST effort?

A. Export the CloudWatch Logs group data to Amazon S3. Use Amazon Macie to query thelogs for the specific IP address and the requested URLs.
B. Configure a CloudWatch Logs subscription to stream the log group to an AmazonOpenSearch Service cluster. Use OpenSearch Service to analyze the logs for the specificIP address and the requested URLs
C. Use CloudWatch Logs Insights and a custom query syntax to analyze the CloudWatchlogs for the specific IP address and the requested URLs.
D. Export the CloudWatch Logs group data to Amazon S3. Use AWS Glue to crawl the S3bucket for only the log entries that contain the specific IP address. Use AWS Glue to viewthe results.
