Exam 8: AWS Certified Security - Specialty (SCS-C01)

A company uses AWS Organization to manage 50 AWS accounts. The finance staff members logs in as AWS IAM users in the FinanceDept AWS account. The staff members need to read the consolidates billing information in the MasterPayer AWS account. They should not be able to view any other resources in the MasterPayer AWS account. IAM access to billing has been enabled in the MasterPayer account. Which of the following approaches grants the finance staff the permissions they require without granting any unnecessary permissions?

A company hosts an application on Amazon EC2 that is subject to specific rules for regulatory compliance. One rule states that traffic to and from the workload must be inspected for network-level attacks. This involves inspecting the whole packet. To comply with this regulatory rule, a security engineer must install intrusion detection software on a c5n.4xlarge EC2 instance. The engineer must then configure the software to monitor traffic to and from the application instances. What should the security engineer do next?

AWS CloudTrail is being used to monitor API calls in an organization. An audit revealed that CloudTrail is failing to deliver events to Amazon S3 as expected. What initial actions should be taken to allow delivery of CloudTrail events to S3? (Choose two.)

A company manages three separate AWS 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 development account requires read access to the archived documents stored in an Amazon S3 bucket in the production account. How should access be granted?

A company has multiple production AWS accounts. Each account has AWS CloudTrail configured to log to a single Amazon S3 bucket in a central account. Two of the production accounts have trails that are not logging anything to the S3 bucket. Which steps should be taken to troubleshoot the issue? (Choose three.)

A company needs to retain log data archives for several years to be compliant with regulations. The log data is no longer used, but it must be retained. What is the MOST secure and cost-effective solution to meet these requirements?

A company had one of its Amazon EC2 key pairs compromised. A Security Engineer must identify which current Linux EC2 instances were deployed and used the compromised key pair. How can this task be accomplished?

A company uses HTTP Live Streaming (HLS) 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 company is implementing a new application in a new AWS account. A VPC and subnets have been created for the application. The application has been peered to an existing VPC in another account in the same AWS Region for database access. Amazon EC2 instances will regularly be created and terminated in the application VPC, but only some of them will need access to the databases in the peered VPC over TCP port 1521. A security engineer must ensure that only the EC2 instances than need access to the databases can access them through the network. How can the security engineer implement this solution?

A company's data lake uses Amazon S3 and Amazon Athena. The company's security engineer has been asked to design an encryption solution that meets the company's data protection requirements. The encryption solution must work with Amazon S3 and keys managed by the company. The encryption solution must be protected in a hardware security module that is validated to Federal information Processing Standards (FIPS) 140-2 Level 3. Which solution meets these requirements?

A company has five AWS accounts and wants to use AWS CloudTrail to log API calls. The log files must be stored in an Amazon S3 bucket that resides in a new account specifically built for centralized services with a unique top-level prefix for each trail. The configuration must also enable detection of any modification to the logs. Which of the following steps will implement these requirements? (Choose three.)

A company recently experienced a DDoS attack that prevented its web server from serving content. The website is static and hosts only HTML, CSS, and PDF files that users download. Based on the architecture shown in the image, what is the BEST way to protect the site against future attacks while minimizing the ongoing operational overhead?

A company plans to move most of its IT infrastructure to AWS. The company wants to leverage its existing on-premises Active Directory as an identity provider for AWS. Which steps should be taken to authenticate to AWS services using the company's on-premises Active Directory? (Choose three).

A company uses an AWS Key Management Service (AWS KMS) CMK to encrypt application data before it is stored. The company's security policy was recently modified to require encryption key rotation annually. A security engineer must ensure that annual global key rotation is enabled for the key without making changes to the application. What should the security engineer do to accomplish this requirement?

A company plans to use custom AMIs to launch Amazon EC2 instances across multiple AWS accounts in a single Region to perform security monitoring and analytics tasks. The EC2 instances are launched in EC2 Auto Scaling groups. To increase the security of the solution, a Security Engineer will manage the lifecycle of the custom AMIs in a centralized account and will encrypt them with a centrally managed AWS KMS CMK. The Security Engineer configured the KMS key policy to allow cross-account access. However, the EC2 instances are still not being properly launched by the EC2 Auto Scaling groups. Which combination of configuration steps should the Security Engineer take to ensure the EC2 Auto Scaling groups have been granted the proper permissions to execute tasks?

Which of the following are valid configurations for using SSL certificates with Amazon CloudFront? (Choose three.)

A company is setting up products to deploy in AWS Service Catalog. Management is concerned that when users launch products, elevated IAM privileges will be required to create resources. How should the company mitigate this concern?

A Security Engineer is building a Java application that is running on Amazon EC2. The application communicates with an Amazon RDS instance and authenticates with a user name and password. Which combination of steps can the Engineer take to protect the credentials and minimize downtime when the credentials are rotated? (Choose two.)

An application uses Amazon Cognito to manage end users' permissions when directly accessing AWS resources, including Amazon DynamoDB. A new feature request reads as follows: Provide a mechanism to mark customers as suspended pending investigation or suspended permanently. Customers should still be able to log in when suspended, but should not be able to make changes. The priorities are to reduce complexity and avoid potential for future security issues. Which approach will meet these requirements and priorities?

A security engineer needs to ensure their company's use of AWS meets AWS security best practices. As part of this, the AWS account root user must not be used for daily work. The root user must be monitored for use, and the security team must be alerted as quickly as possible if the root user is used. Which solution meets these requirements?
