NEW QUESTION # 250
A security engineer uses Amazon Macie to scan a company's Amazon S3 buckets for sensitive data. The company has many S3 buckets and many objects stored in the S3 buckets. The security engineer must identify S3 buckets that contain sensitive data and must perform additional scanning on those S3 buckets.
Which solution will meet these requirements with the LEAST administrative overhead?
Answer: A
Explanation:
Amazon Macie'sautomated sensitive data discoveryis designed for exactly this: at scale, Macie continuously evaluates andsamplesobjects across S3 buckets to identify where sensitive data (PII, financial data, credentials, etc.) is likely present. This gives the security engineer a low-touch way toidentify which buckets contain sensitive datawithout having to orchestrate per-bucket scanning workflows. Once Macie flags buckets with sensitive data findings, the engineer can then prioritize and runadditional, more targeted scanning(for example, deeper classification jobs on those specific buckets) rather than scanning everything exhaustively all the time.
NEW QUESTION # 251
A company needs to follow security best practices to deploy resources from an AWS CloudFormation template. The CloudFormation template must be able to configure sensitive database credentials. The company already uses AWS Key Management Service (AWS KMS) and AWS Secrets Manager.
Which solution will meet the requirements?
Answer: A
Explanation:
AWS CloudFormationdynamic referencesprovide a secure mechanism for retrieving sensitive values from AWS Secrets Manager at stack creation or update time. According to the AWS Certified Security - Specialty documentation, dynamic references ensure that sensitive data such as database credentials arenever stored in plaintextin CloudFormation templates, parameters, stack metadata, or logs.
When a dynamic reference to Secrets Manager is used, CloudFormation retrieves the secret value at runtime and passes it securely to the resource that requires it. The secret value is not exposed to users who view the template, stack, or change sets.
Option B is insecure because parameters can be exposed through the CloudFormation console and APIs.
Option C is incorrect because SecureString parameters are a feature of AWS Systems Manager Parameter Store, not Secrets Manager. Option D is invalid because KMS encrypts data but does not store secrets or manage secret rotation.
AWS best practices clearly state thatCloudFormation dynamic references to Secrets Managerare the recommended solution for securely handling sensitive configuration values.

NEW QUESTION # 252
CloudFormation stack deployments fail for some users due to permission inconsistencies.
Which combination of steps will ensure consistent deployments MOST securely? (Select THREE.)
Answer: A,E,F
Explanation:
AWS best practices require CloudFormation to assume a dedicated service role. This ensures consistent permissions regardless of the user. Users must have iam:PassRole permission to pass the role. Updating stacks to use the service role enforces uniform deployment behavior.

NEW QUESTION # 253
A company's data scientists want to create artificial intelligence and machine learning (AI/ML) training models by using Amazon SageMaker. The training models will use large datasets in an Amazon S3 bucket. The datasets contain sensitive information.
On average, the data scientists need 30 days to train models. The S3 bucket has been secured appropriately. The company's data retention policy states that all data that is older than 45 days must be removed from the S3 bucket.
Which action should a security engineer take to enforce this data retention policy?
Answer: A
Explanation:
Amazon S3 Lifecycle rules provide a native, fully managed mechanism to automatically transition or delete objects based on their age. According to the AWS Certified Security - Specialty Official Study Guide, S3 Lifecycle policies are the recommended and most secure method for enforcing data retention requirements because they operate automatically, consistently, and without custom code.
By configuring a lifecycle rule to delete objects after 45 days, the company ensures that sensitive datasets are retained long enough to support the 30-day model training process while remaining compliant with the data retention policy. Lifecycle rules are enforced by Amazon S3 itself and apply uniformly to all objects in the bucket or to objects that match specific prefixes or tags.
NEW QUESTION # 254
An ecommerce website was down for 1 hour following a DDoS attack. Users were unable to connect to the website during the attack period. The ecommerce company ' s security team is worried about future potential attacks and wants to prepare for such events. The company needs to minimize downtime in its response to similar attacks in the future.
Which steps would help achieve this? (Select TWO.)
Answer: B,C
Explanation:
To minimize downtime during future DDoS events, the company should use services that provideactive DDoS protection and rapid mitigationat scale.AWS Shield Advanced(Option B) is designed for enhanced DDoS protection for internet-facing applications. It provides expanded detection and mitigation capabilities, cost protection in certain cases, and-critically-access to theAWS DDoS Response Team (DRT)through AWS Support so the company can engage experts during an attack to reduce impact and restore availability faster.
In addition,AWS WAF(Option E) helps mitigateapplication-layer (Layer 7)attacks that often accompany DDoS events (such as HTTP floods, bot-driven abuse, and known exploit patterns). WAF can block or challenge suspicious requests, apply rate-based controls, and use managed rule groups to reduce malicious traffic before it reaches the origin, improving resilience and availability.
Option A is incorrect because GuardDuty is a detection service; it does not automatically block traffic. Option C (Flow Logs + Lambda + SG blocks) is slow and brittle for DDoS because attackers are often distributed across many IPs and can change rapidly; security group updates are not an effective DDoS mitigation strategy. Option D is more about configuration governance and remediation, not real-time DDoS traffic mitigation.
