Questions 103

A Security Engineer is troubleshooting an issue with a company's custom logging application. The application logs are written to an Amazon S3 bucket with event notifications enabled to send events lo an Amazon SNS topic. All logs are encrypted at rest using an IAM KMS CMK. The SNS topic is subscribed to an encrypted Amazon SQS queue. The logging application polls the queue for new messages that contain metadata about the S3 object. The application then reads the content of the object from the S3 bucket for indexing.

The Logging team reported that Amazon CloudWatch metrics for the number of messages sent or received is showing zero. No togs are being received.

What should the Security Engineer do to troubleshoot this issue?

Questions 104

Within a VPC, a corporation runs an Amazon RDS Multi-AZ DB instance. The database instance is connected to the internet through a NAT gateway via two subnets.

Additionally, the organization has application servers that are hosted on Amazon EC2 instances and use the RDS database. These EC2 instances have been deployed onto two more private subnets inside the same VPC. These EC2 instances connect to the internet through a default route via the same NAT gateway. Each VPC subnet has its own route table.

The organization implemented a new security requirement after a recent security examination. Never allow the database instance to connect to the internet. A security engineer must perform this update promptly without interfering with the network traffic of the application servers.

How will the security engineer be able to comply with these requirements?

Options:
A.

Remove the existing NAT gateway. Create a new NAT gateway that only the application server subnets can use.

B.

Configure the DB instanceג€™s inbound network ACL to deny traffic from the security group ID of the NAT gateway.

C.

Modify the route tables of the DB instance subnets to remove the default route to the NAT gateway.

D.

Configure the route table of the NAT gateway to deny connections to the DB instance subnets.

Questions 105

A company operates a web application that runs on Amazon EC2 instances. The application listens on port 80 and port 443. The company uses an Application Load Balancer (ALB) with AWS WAF to terminate SSL and to forward traffic to the application instances only on port 80.

The ALB is in public subnets that are associated with a network ACL that is named NACL1. The application instances are in dedicated private subnets that are associated with a network ACL that is named NACL2. An Amazon RDS for PostgreSQL DB instance that uses port 5432 is in a dedicated private subnet that is associated with a network ACL that is named NACL3. All the network ACLs currently allow all inbound and outbound traffic.

Which set of network ACL changes will increase the security of the application while ensuring functionality?

Options:
A.

Make the following changes to NACL3:• Add a rule that allows inbound traffic on port 5432 from NACL2.• Add a rule that allows outbound traffic on ports 1024-65536 to NACL2.• Remove the default rules that allow all inbound and outbound traffic.

B.

Make the following changes to NACL3:• Add a rule that allows inbound traffic on port 5432 from the CIDR blocks of the application instance subnets.• Add a rule that allows outbound traffic on ports 1024-65536 to the application instance subnets.• Remove the default rules that allow all inbound and outbound traffic.

C.

Make the following changes to NACL2:• Add a rule that allows outbound traffic on port 5432 to the CIDR blocks of the RDS subnets.• Remove the default rules that allow all inbound and outbound traffic.

D.

Make the following changes to NACL2:• Add a rule that allows inbound traffic on port 5432 from the CIDR blocks of the RDS subnets.• Add a rule that allows outbound traffic on port 5432 to the RDS subnets.

Questions 106

For compliance reasons a Security Engineer must produce a weekly report that lists any instance that does not have the latest approved patches applied. The Engineer must also ensure that no system goes more than 30 days without the latest approved updates being applied

What would the MOST efficient way to achieve these goals?

Options:
A.

Use Amazon inspector to determine which systems do not have the latest patches applied, and after 30 days, redeploy those instances with the latest AMI version

B.

Configure Amazon EC2 Systems Manager to report on instance patch compliance and enforce updates during the defined maintenance windows

C.

Examine IAM CloudTrail togs to determine whether any instances have not restarted in the last 30 days, and redeploy those instances

D.

Update the AMls with the latest approved patches and redeploy each instance during the defined maintenance window

Questions 107

A company has a requirement that no Amazon EC2 security group can allow SSH access from the CIDR block 0.0.0.070. The company wants to monitor compliance with this requirement at all times and wants to receive a near-real-time notification if any security group is noncompliant.

A security engineer has configured AWS Config and will use the restricted-ssh managed rule to monitor the security groups.

What should the security engineer do next to meet these requirements?

Options:
A.

Configure AWS Config to send its configuration snapshots to an Amazon S3 bucket. Create an AWS Lambda function to run on a PutEvent to the S3 bucket. Configure the Lambda function to parse the snapshot for a compliance change to the restricled-ssh managed rule. Configure the Lambda function to send a notification to an Amazon Simple Notification Service (Amazon SNS) topic if a change is discovered.

B.
