Question 301

A security team needs to verify that CloudTrail log files stored in Amazon S3 have not been modified after delivery. Which CloudTrail capability should the team use?

1. CloudTrail Insights
2. Advanced event selectors
3. Event history
4. Log file integrity validation

Correct Answer: 4

Explanation

CloudTrail log file integrity validation helps determine whether CloudTrail log files have been modified, deleted, or otherwise altered after they were delivered to the configured S3 bucket. CloudTrail uses digest files and cryptographic techniques to support this validation. This capability is particularly useful when logs may be required for forensic investigations, compliance evidence, or security auditing. Organizations should also restrict access to the destination bucket and use appropriate retention controls. Integrity validation complements, rather than replaces, secure storage and access-control protections for audit logs.

Question 302

A company wants different applications to access specific prefixes in a shared S3 bucket using separate policies. Which feature is designed for this type of access management?

1. S3 Access Points
2. S3 Transfer Acceleration
3. S3 Lifecycle
4. S3 Inventory

Correct Answer: 1

Explanation

Amazon S3 Access Points provide dedicated access endpoints and policies for applications or groups that need to access a shared S3 bucket. Instead of maintaining one increasingly complex bucket policy for every application, organizations can create separate access points with permissions appropriate to each use case. Access points can also have network-origin restrictions. This design can simplify authorization management while supporting least privilege. The underlying bucket remains important because its policy and other account-level S3 controls can still affect the resulting access behavior.

Question 303

A security administrator wants AWS KMS to automatically rotate the key material for a customer managed symmetric KMS key on a recurring basis. Which feature should be enabled?

1. KMS grants
2. Automatic key rotation
3. Imported key material
4. Key aliases

Correct Answer: 2

Explanation

AWS KMS automatic key rotation can periodically rotate the cryptographic key material associated with eligible customer managed symmetric KMS keys. Applications can generally continue using the same logical KMS key while KMS manages the underlying key material. This reduces the operational burden of manually creating replacement keys solely for routine rotation requirements. Automatic rotation does not change the permissions granted by the key policy or IAM policies. Organizations should still review key access, usage, lifecycle requirements, and logging because rotation alone does not provide complete key-management security.

Question 304

A large organization wants to grant access to S3 data based on users and groups while avoiding the creation of numerous individual bucket policies. Which AWS capability is specifically designed to simplify this type of data access management?

1. S3 Inventory
2. S3 Access Grants
3. S3 Transfer Acceleration
4. S3 Object Lock

Correct Answer: 2

Explanation

Amazon S3 Access Grants can help organizations manage data access at scale by mapping identities and groups to specific S3 locations and permissions. It is particularly useful when an organization has many users, groups, applications, and datasets that require different access levels. Instead of creating increasingly complex permissions for every individual use case, administrators can centralize and simplify data-access management. Access Grants should still be designed according to least privilege, and organizations should continue monitoring access and protecting the underlying S3 resources.

Question 305

A security team wants CloudWatch Logs to generate a metric whenever a CloudTrail event indicates an unauthorized API operation. Which CloudWatch feature should be configured?

1. Metric filter
2. Dashboard widget
3. Synthetics canary
4. Contributor Insights rule

Correct Answer: 1

Explanation

A CloudWatch Logs metric filter can search incoming log events for patterns that represent security conditions, such as unauthorized API activity recorded by CloudTrail. When matching events occur, the filter can publish a metric that can be monitored or used to trigger a CloudWatch alarm. This approach allows organizations to turn specific log patterns into measurable security signals. Security teams should carefully define the event pattern and alarm threshold to reduce false positives while ensuring meaningful unauthorized activity is investigated promptly.

Question 306

A security operations team wants analysts to manually trigger a predefined response workflow from a Security Hub finding. Which capability can provide this functionality?

1. Security Hub standards
2. Security Hub insights
3. Security Hub custom actions
4. Security Hub control mappings

Correct Answer: 3

Explanation

Security Hub custom actions allow organizations to define actions that can be associated with findings and used to initiate downstream workflows. A security team can create an action that, for example, sends a finding to an automation process or invokes an EventBridge rule. This enables analysts to start standardized response procedures without manually performing every step. Custom actions are useful when organizations want consistent incident-response workflows while retaining analyst control. They can complement Security Hub automation rules and other AWS security-service integrations.

Question 307

An organization has hundreds of AWS accounts and wants to centrally aggregate AWS Config data so security administrators can query resource configuration information across accounts and Regions. Which feature should be used?

1. Config conformance packs
2. Config aggregator
3. Config remediation rule
4. Config timeline

Correct Answer: 2

Explanation

An AWS Config aggregator provides a centralized view of resource configuration and compliance information across multiple AWS accounts and Regions. This is useful for organizations that need centralized security and governance visibility without manually checking every account. Administrators can use aggregated information to identify configuration trends, investigate resources, and support compliance reporting. The aggregator does not itself enforce security configurations. Organizations should combine centralized visibility with Config rules, appropriate remediation workflows, IAM controls, and organizational governance to address identified configuration problems.

Question 308

A company stores sensitive customer information in S3 and wants a managed service to detect malware in newly uploaded objects before they are used by downstream applications. Which capability is most appropriate?

1. Amazon Inspector
2. Amazon Macie
3. GuardDuty Malware Protection for S3
4. AWS Artifact

Correct Answer: 3

Explanation

GuardDuty Malware Protection for S3 is designed to help detect potentially malicious files uploaded to S3 buckets. It provides a managed malware-scanning capability that can be integrated into workflows where objects should be assessed before downstream processing. This can add an important security layer for file-upload applications and data-ingestion pipelines. Organizations should still use appropriate IAM policies, bucket controls, encryption, logging, and application validation. Malware scanning is not a replacement for secure application design or controls that restrict who can upload and consume objects.

Question 309

A web application is protected by AWS WAF, and the security team wants AWS-maintained protections for common web vulnerabilities without writing every detection rule manually. Which capability should be used?

1. Rate-based rules
2. IP set
3. CAPTCHA action
4. Managed rule groups

Correct Answer: 4

Explanation

AWS WAF managed rule groups provide collections of preconfigured rules designed to detect common web threats and attack patterns. Using managed rules can reduce the administrative effort required to create and maintain every rule manually. Security teams should review the behavior of managed rule groups in the context of their applications because legitimate requests can sometimes match security rules. Testing and monitoring are important before enabling blocking actions broadly. Managed rule groups can be combined with custom rules, rate-based controls, and application-specific protections for layered web security.

Question 310

An organization wants S3 objects to automatically belong to the bucket owner rather than relying on object ACLs for ownership decisions. Which S3 setting should be used?

1. Bucket owner enforced
2. Transfer Acceleration
3. Versioning suspended
4. Static website hosting

Correct Answer: 1

Explanation

The S3 Object Ownership setting called Bucket owner enforced disables ACLs and makes the bucket owner automatically own objects uploaded to the bucket. This simplifies access management by reducing reliance on object-level ACLs and allowing organizations to manage authorization primarily through IAM and bucket policies. It is especially useful in centralized data repositories where multiple accounts or applications upload objects. Security teams should review existing applications before enabling the setting because workflows that depend on ACLs may require changes. Simplifying authorization can also reduce configuration complexity.

Question 311

A company distributes private content through Amazon CloudFront and wants access to expire automatically after a specified time. Which mechanism can provide this control?

1. CloudFront signed URLs or signed cookies
2. S3 lifecycle rules
3. Route 53 DNSSEC
4. AWS Config rules

Correct Answer: 1

Explanation

CloudFront signed URLs and signed cookies can restrict access to private content based on conditions such as expiration time. A signed URL is useful when granting access to an individual object, while signed cookies can support access to multiple restricted objects. These mechanisms allow applications to provide temporary access without making the underlying content publicly accessible. Security teams should also protect the signing credentials, configure the CloudFront distribution appropriately, and restrict direct access to the origin. Expiration controls should match the application’s security and usability requirements.

Question 312

A security engineer is configuring AWS Network Firewall and needs rules that maintain connection state while evaluating traffic flows. Which rule type should be selected?

1. Stateless rule group
2. Network ACL
3. Stateful rule group
4. Security group

Correct Answer: 3

Explanation

AWS Network Firewall stateful rule groups evaluate network traffic while maintaining awareness of connection state. This allows rules to make decisions based on the broader context of traffic flows rather than treating every packet independently. Stateful rules can be useful when implementing more sophisticated network inspection and filtering requirements. Stateless rule groups operate differently and can provide fast packet-level filtering before traffic reaches stateful inspection. Security teams should design routing and rule evaluation carefully so traffic reaches the intended inspection path and legitimate connections are not unintentionally disrupted.

Question 313

A company wants to record requests made directly to objects in an S3 bucket for security analysis. Which S3 logging capability can provide detailed request records?

1. S3 server access logging
2. S3 Transfer Acceleration
3. S3 Batch Operations
4. S3 Inventory

Correct Answer: 1

Explanation

S3 server access logging can provide detailed records about requests made against an S3 bucket. These logs can contain information useful for investigating access patterns, identifying unexpected clients, and supporting security analysis. Server access logging is distinct from CloudTrail, which records supported API activity and provides a different level of event information. Organizations should secure the destination used for log storage and establish suitable retention policies. For comprehensive monitoring, S3 access logs can be used alongside CloudTrail, IAM analysis, and other security telemetry.

Question 314

A security administrator needs to permanently retire a customer managed KMS key but wants to prevent accidental immediate deletion. What happens when KMS key deletion is scheduled?

1. The key is immediately destroyed
2. The key is automatically exported
3. The key becomes publicly inaccessible
4. KMS places the key into a pending deletion state

Correct Answer: 4

Explanation

When deletion of a customer managed KMS key is scheduled, AWS KMS places the key into a pending deletion state for the configured waiting period. During this period, authorized administrators can cancel the deletion if it was requested accidentally or if the key is still required. This waiting period helps reduce the risk of irreversible key deletion causing data loss. Before scheduling deletion, security teams should determine whether encrypted data still depends on the key and verify that appropriate recovery, retention, and dependency procedures have been completed.

Question 315

A security team wants GuardDuty to monitor runtime behavior of supported workloads for suspicious activity rather than relying only on control-plane events. Which capability can provide this visibility?

1. GuardDuty S3 Protection
2. GuardDuty Runtime Monitoring
3. GuardDuty IP lists
4. GuardDuty trusted IP lists

Correct Answer: 2

Explanation

GuardDuty Runtime Monitoring is designed to provide runtime security visibility for supported workloads and can help detect suspicious behavior occurring while applications are running. Runtime telemetry can provide additional context beyond traditional control-plane and network-based detection. This can be valuable when investigating compromised workloads because an attacker may perform malicious actions after gaining access to a running environment. Organizations should enable the appropriate runtime protection for supported workloads and integrate findings with broader security workflows, while continuing to apply least privilege, patching, network controls, and monitoring.

Question 316

A company wants to copy backups from one AWS account into a separate security account so that a compromise of the production account does not automatically eliminate all backup copies. Which approach is appropriate?

1. Store all backups in the production account
2. Use cross-account backup copies
3. Disable backup encryption
4. Share administrator credentials between accounts

Correct Answer: 2

Explanation

Cross-account backup copies can provide an additional isolation boundary by storing backup data in a separate AWS account. This can reduce the risk that an attacker who compromises a production account can directly delete every available backup. Organizations should apply appropriate backup policies, encryption, access controls, and retention protections to the destination account. The backup account should have tightly restricted administrative access and should not rely on the same credentials as the production environment. Separate-account backups are particularly useful as part of ransomware-resilience planning.

Question 317

A company exposes an internal API through a private API Gateway endpoint and wants to restrict which VPCs can invoke the API. Which control can help enforce this restriction?

1. CloudFront origin access control
2. S3 Access Grants
3. API Gateway resource policy
4. AWS Backup policy

Correct Answer: 3

Explanation

An API Gateway resource policy can control access to an API based on specified principals, VPC endpoints, accounts, or other supported conditions. For a private API, resource policies can help restrict which network locations or identities are permitted to invoke the endpoint. This creates an additional authorization layer beyond the network configuration itself. Security teams should also verify the VPC endpoint configuration, IAM authorization, routing, and application authentication requirements. Resource policies should follow least privilege and should be tested carefully to avoid unintentionally blocking legitimate internal applications.

Question 318

A security administrator wants to identify which AWS services and actions an IAM identity has actually accessed so unused permissions can be removed. Which IAM feature can provide this information?

1. Service last accessed information
2. IAM password policy
3. Access key rotation
4. IAM credential report

Correct Answer: 1

Explanation

IAM service last accessed information can help administrators determine when an IAM principal last accessed supported AWS services. This information can support least-privilege reviews by identifying services that may no longer be required by a role or user. It should not be treated as proof that every unused permission can immediately be removed because service-level information may not represent every individual action or resource dependency. Security teams should combine this information with policy analysis, application testing, CloudTrail evidence, and business requirements before reducing permissions.

Question 319

A security analytics platform needs access to security data stored in Amazon Security Lake. Which Security Lake capability can provide controlled access to the data?

1. Security Lake administrator account
2. Security Lake subscriber
3. AWS Artifact report
4. Macie discovery job

Correct Answer: 2

Explanation

Amazon Security Lake subscribers provide controlled access to Security Lake data for supported analytics and security operations use cases. A subscriber can be configured to consume relevant security data rather than giving broad direct access to the underlying data store. This helps organizations integrate Security Lake with security information and event management, security analytics, or other supported tools while maintaining controlled permissions. Administrators should define which data sources and Regions a subscriber can access and apply least-privilege permissions to reduce unnecessary exposure of centralized security telemetry.

Question 320

A company uses AWS Config to detect noncompliant resources and wants remediation to occur automatically through a predefined Systems Manager workflow. Which feature can implement this design?

1. Config advanced queries
2. Config remediation actions
3. Config configuration history
4. Config resource timeline

Correct Answer: 2

Explanation

AWS Config remediation actions can automatically invoke predefined remediation workflows when resources are identified as noncompliant. Systems Manager Automation documents can be used to perform standardized corrective actions, allowing organizations to respond consistently without requiring manual intervention for every finding. Security teams should test remediation workflows carefully because automated changes can affect production workloads. Appropriate IAM permissions, logging, exception handling, and approval requirements should also be considered. Automated remediation is most effective when the compliance rule accurately represents the organization’s intended security configuration.
