AWS Certified Security Specialty SCS-C01 Part 1 Quiz Format

The Security team believes that a former employee may have gained unauthorized access to AWS resources sometime in the past 3 months by using an identified access key. What approach would enable the Security team to find out what the former employee may have done within AWS?

The Security Engineer implemented a new vault lock policy for 10TB of data and called initiatevault-lock 12 hours ago. The Audit team identified a typo that is allowing incorrect access to the vault. What is the MOST cost-effective way to correct this?

A company wants to control access to its AWS resources by using identities and groups that are defined in its existing Microsoft Active Directory. What must the company create in its AWS account to map permissions for AWS services to Active Directory user attributes?

A company has contracted with a third party to audit several AWS accounts. To enable the audit, cross-account IAM roles have been created in each account targeted for audit. The Auditor is having trouble accessing some of the accounts. Which of the following may be causing this problem? (Choose three.)

Compliance requirements state that all communications between company on-premises hosts and EC2 instances be encrypted in transit. Hosts use custom proprietary protocols for their communication, and EC2 instances need to be fronted by a load balancer for increased availability. Which of the following solutions will meet these requirements?

An application is currently secured using network access control lists and security groups. Web servers are located in public subnets behind an Application Load Balancer (ALB); application servers are located in private subnets. How can edge security be enhanced to safeguard the Amazon EC2 instances against attack? (Choose two.)

A Security Administrator is restricting the capabilities of company root user accounts. The company uses AWS Organizations and has enabled it for all feature sets, including consolidated billing. The top-level account is used for billing and administrative purposes, not for operational AWS resource purposes. How can the Administrator restrict usage of member root user accounts across the organization?

A Systems Engineer has been tasked with configuring outbound mail through Simple Email Service (SES) and requires compliance with current TLS standards. The mail application should be configured to connect to which of the following endpoints and corresponding ports?

A threat assessment has identified a risk whereby an internal employee could exfiltrate sensitive data from production host running inside AWS (Account 1). The threat was documented as follows:

Threat description: A malicious actor could upload sensitive data from Server X by configuring credentials for an AWS account (Account 2) they control and uploading data to an Amazon S3 bucket within their control.

Server X has outbound internet access configured via a proxy server. Legitimate access to S3 is required so that the application can upload encrypted files to an S3 bucket. Server X is currently using an IAM instance role. The proxy server is not able to inspect any of the server communication due to TLS encryption. Which of the following options will mitigate the threat? (Choose two.)

A company will store sensitive documents in three Amazon S3 buckets based on a data classification scheme of “Sensitive,” “Confidential,” and “Restricted.” The security solution must meet all of the following requirements: Each object must be encrypted using a unique key. Items that are stored in the “Restricted” bucket require two-factor authentication for decryption. AWS KMS must automatically rotate encryption keys annually. Which of the following meets these requirements?

An organization wants to deploy a three-tier web application whereby the application servers run on Amazon EC2 instances. These EC2 instances need access to credentials that they will use to authenticate their SQL connections to an Amazon RDS DB instance. Also, AWS Lambda functions must issue queries to the RDS database by using the same database credentials. The credentials must be stored so that the EC2 instances and the Lambda functions can access them. No other access is allowed. The access logs must record when the credentials were accessed and by whom. What should the Security Engineer do to meet these requirements?

A company has a customer master key (CMK) with imported key materials. Company policy requires that all encryption keys must be rotated every year. What can be done to implement the above policy?

A water utility company uses a number of Amazon EC2 instances to manage updates to a fleet of 2,000 Internet of Things (IoT) field devices that monitor water quality. These devices each have unique access credentials. An operational safety policy requires that access to specific credentials is independently auditable. What is the MOST cost-effective way to manage the storage of credentials?

An organization is using Amazon CloudWatch Logs with agents deployed on its Linux Amazon EC2 instances. The agent configuration files have been checked and the application log files to be pushed are configured correctly. A review has identified that logging from specific instances is missing. Which steps should be taken to troubleshoot the issue? (Choose two.)

A Security Engineer must design a solution that enables the Incident Response team to audit for changes to a user’s IAM permissions in the case of a security incident. How can this be accomplished?

A company has complex connectivity rules governing ingress, egress, and communications between Amazon EC2 instances. The rules are so complex that they cannot be implemented within the limits of the maximum number of security groups and network access control lists (network ACLs). What mechanism will allow the company to implement all required network rules without incurring additional cost?

A Developer’s laptop was stolen. The laptop was not encrypted, and it contained the SSH key used to access multiple Amazon EC2 instances. A Security Engineer has verified that the key has not been used, and has blocked port 22 to all EC2 instances while developing a response plan. How can the Security Engineer further protect currently running instances?

A Security Administrator has a website hosted in Amazon S3. The Administrator has been given the following requirements: Users may access the website by using an Amazon CloudFront distribution. Users may not access the website directly by using an Amazon S3 URL. Which configurations will support these requirements? (Choose two.)

An application outputs logs to a text file. The logs must be continuously monitored for security incidents. Which design will meet the requirements with MINIMUM effort?

A company requires that IP packet data be inspected for invalid or malicious content. Which of the following approaches achieve this requirement? (Choose two.)
