AWS Certified Security - Specialty Questions and Answers

Question 113

An audit reveals that a company has multiple applications that are susceptible to SQL injection attacks. The company wants a formal penetration testing program as soon as possible to identify future risks in applications that are deployed on AWS.

The company's legal department is concerned that such testing might create AWS abuse notifications and violate the AWS Acceptable Use policy. The company must ensure compliance in these areas.

Which testing procedures are allowed on AWS as part of a penetration testing strategy? (Select TWO.)

Options:

A.

Port scanning inside the company's VPC

B.

Brute force test of the Amazon S3 bucket namespace

C.

Use of a SQL injection tool on the company's web application against an Amazon RDS for PostgreSQL DB instance

D.

Packet flooding of the company's web application

E.

DNS zone walking through Amazon Route 53 hosted zones

Question 114

A company runs workloads in the us-east-1 Region. The company has never deployed resources to other AWS Regions and does not have any multi-Region resources.

The company needs to replicate its workloads and infrastructure to the us-west-1 Region.

A security engineer must implement a solution that uses AWS Secrets Manager to store secrets in both Regions. The solution must use AWS Key Management Service(AWS KMS) to encrypt the secrets. The solution must minimize latency and must be able to work if only one Region is available.

The security engineer uses Secrets Manager to create the secrets in us-east-1.

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

Options:

A.

Encrypt the secrets in us-east-1 by using an AWS managed KMS key. Replicate the secrets to us-west-1. Encrypt the secrets in us-west-1 by using a newAWS managed KMS key in us-west-1.

B.

Encrypt the secrets in us-east-1 by using an AWS managed KMS key. Configure resources in us-west-1 to call the Secrets Manager endpoint in us-east-1.

C.

Encrypt the secrets in us-east-1 by using a customer managed KMS key. Configure resources in us-west-1 to call the Secrets Manager endpoint in us-east-1.

D.

Encrypt the secrets in us-east-1 by using a customer managed KMS key. Replicate the secrets to us-west-1. Encrypt the secrets in us-west-1 by using thecustomer managed KMS key from us-east-1.

Question 115

A company manages three separate IAM accounts for its production, development, and test environments, Each Developer is assigned a unique IAM user under the development account. A new application hosted on an Amazon EC2 instance in the developer account requires read access to the archived documents stored in an Amazon S3 bucket in the production account.

How should access be granted?

Options:

A.

Create an IAM role in the production account and allow EC2 instances in the development account to assume that role using the trust policy. Provide read access for the required S3 bucket to this role.

B.

Use a custom identity broker to allow Developer IAM users to temporarily access the S3 bucket.

C.

Create a temporary IAM user for the application to use in the production account.

D.

Create a temporary IAM user in the production account and provide read access to Amazon S3. Generate the temporary IAM user's access key and secret key and store these on the EC2 instance used by the application in the development account.

Question 116

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.
