A company needs an automated vulnerability management service that continually scans AWS workloads for software vulnerabilities. Which AWS service will meet these requirements?
Correct Answer: B
Explanation The correct answer is B. Amazon Inspector. Amazon Inspector is an automated vulnerability management service that continually scans AWS workloads for software vulnerabilities and unintended network exposure. Amazon Inspector automatically discovers workloads, such as Amazon EC2 instances, containers, and Lambda functions, and scans them for software vulnerabilities and unintended network exposure12. Amazon GuardDuty is a threat detection service that monitors your AWS accounts and workloads for malicious or unauthorized activity. Amazon GuardDuty does not scan for software vulnerabilities, but rather analyzes AWS CloudTrail, Amazon VPC Flow Logs, and DNS logs to detect threats such as compromised credentials, backdoors, or crypto mining3. AWS Security Hub is a security and compliance service that aggregates and prioritizes security findings from multiple AWS services and partner solutions. AWS Security Hub does not scan for software vulnerabilities, but rather provides a comprehensive view of your security posture across your AWS accounts4. AWS Shield is a managed service that protects your web applications and network resources from distributed denial-of-service (DDoS) attacks. AWS Shield does not scan for software vulnerabilities, but rather provides detection and mitigation of DDoS attacks at the network and application layers5.

Question 182
Which group shares responsibility with AWS for security and compliance of AWS accounts and resources?
Correct Answer: B
Explanation Customers share responsibility with AWS for security and compliance of AWS accounts and resources. This is part of the AWS shared responsibility model, which defines the division of responsibilities between AWS and the customer for security and compliance. AWS is responsible for the security of the cloud, which includes the physical and environmental controls of the AWS global infrastructure, such as power, cooling, fire suppression, and physical access. The customer is responsible for the security in the cloud, which includes the configuration and management of the AWS resources and applications, such as identity and access management, encryption, firewall, and backup. For more information, see AWS Shared Responsibility Model and AWS Cloud Security.
Question 183
Which AWS Well-Architected Framework concept represents a system's ability to remain functional when the system encounters operational problems?
Correct Answer: B
Explanation The AWS Well-Architected Framework is a set of best practices and guidelines for designing and operating systems in the cloud. The framework consists of five pillars: operational excellence, security, reliability, performance efficiency, and cost optimization. The concept of elasticity represents a system's ability to adapt to changes in demand by scaling resources up or down automatically. Therefore, the correct answer is B. You can learn more about the AWS Well-Architected Framework and its pillars from this page.
Question 184
Which of the following is a benefit of using an AWS managed service?
Correct Answer: A
This is a benefit of using an AWS managed service, such as Amazon S3, Amazon DynamoDB, or AWS Lambda. AWS managed services are fully managed by AWS, which means that AWS handles the provisioning, scaling, patching, backup, and recovery of the underlying infrastructure and software. This reduces the operational overhead for the company's IT staff, who can focus on their core business logic and innovation. You can learn more about the AWS managed services from this webpage or this digital course.
Question 185
Which task requires the use of AWS account root user credentials?
Correct Answer: C
The creation of an organization in AWS Organizations requires the use of AWS account root user credentials. The AWS account root user is the email address that was used to create the AWS account. The root user has complete access to all AWS services and resources in the account, and can perform sensitive tasks such as changing the account settings, closing the account, or creating an organization. The root user credentials should be used sparingly and securely, and only for tasks that cannot be performed by IAM users or roles4
