Question 41

Which AWS service can be used to query and analyze log data stored in Amazon CloudWatch Logs?

1. Amazon Athena
2. CloudWatch Logs Insights
3. AWS Artifact
4. Amazon Macie

Correct Answer: 2

Explanation

CloudWatch Logs Insights provides an interactive way to query and analyze log data stored in Amazon CloudWatch Logs. Security teams can use it to search large volumes of logs, identify suspicious activity, troubleshoot security events, and investigate patterns across applications and AWS resources. Queries can filter events, calculate statistics, and produce visualizations. This is different from Amazon Athena, which is commonly used to query data stored in Amazon S3. Effective log analysis depends on collecting the appropriate log sources and retaining them according to security and operational requirements.

Question 42

An organization wants all AWS accounts to send CloudTrail management events to a centralized S3 bucket. Which approach is most appropriate?

1. Individual IAM users in each account
2. An organization trail
3. A separate security group
4. An S3 lifecycle policy

Correct Answer: 2

Explanation

An organization trail can be configured through AWS CloudTrail to provide centralized logging for accounts within an AWS Organization. This helps security teams maintain consistent API activity records across multiple accounts instead of relying on administrators to configure trails independently. Centralized CloudTrail logs can be delivered to an S3 bucket and protected with appropriate bucket policies, encryption, and access controls. Organizations should also consider log integrity, retention, monitoring, and restricted administrative access to the centralized logging destination.

Question 43

A security team wants an automated response whenever GuardDuty generates a high-severity finding. Which combination can provide this automation?

1. EventBridge and Lambda
2. Route 53 and ACM
3. S3 Glacier and EFS
4. CloudFront and Direct Connect

Correct Answer: 1

Explanation

Amazon EventBridge can detect events generated by AWS security services and route matching events to targets such as AWS Lambda. A security team can create an EventBridge rule that matches specific GuardDuty findings and invokes a Lambda function to perform an automated response. Depending on the incident, the function could isolate an EC2 instance, modify security controls, or initiate an investigation workflow. Automated remediation should be carefully designed, tested, and limited to appropriate conditions to prevent legitimate resources from being disrupted by false positives.

Question 44

Which AWS service is specifically designed to test how workloads respond to controlled failures and disruptions?

1. AWS Fault Injection Service
2. AWS Config
3. Amazon Inspector
4. AWS Artifact

Correct Answer: 1

Explanation

AWS Fault Injection Service allows organizations to conduct controlled experiments that introduce failures or disruptions into supported AWS workloads. Security and resilience teams can use these experiments to validate incident response procedures, recovery mechanisms, monitoring, and system behavior under stressful conditions. Experiments should be carefully planned with appropriate permissions, scope, safeguards, and rollback procedures. Fault Injection Service is particularly relevant when organizations need evidence that documented response and recovery procedures actually work rather than simply assuming that they will function correctly during a real incident.

Question 45

An investigation identifies a compromised EC2 instance. The team wants to preserve evidence before terminating or modifying the instance. What should be prioritized?

1. Capture relevant forensic artifacts
2. Delete all CloudTrail logs
3. Rotate every AWS account password
4. Remove the instance immediately

Correct Answer: 1

Explanation

Preserving relevant forensic artifacts should be prioritized before actions that could destroy or alter evidence. Depending on the investigation, artifacts may include system logs, application logs, memory information, disk snapshots, network data, and relevant AWS service records. Investigators should document collection procedures and protect the integrity of collected evidence. Immediate termination may eliminate valuable evidence needed to determine the attacker’s actions and root cause. Containment can still be performed carefully while preserving appropriate artifacts for later analysis.

Question 46

Which AWS service can help identify relationships between users, resources, IP addresses, and activities during an investigation?

1. Amazon Detective
2. AWS WAF
3. AWS Certificate Manager
4. Amazon Macie

Correct Answer: 1

Explanation

Amazon Detective analyzes security-related activity and relationships to help investigators understand security events. It can provide context around entities such as IAM principals, EC2 instances, IP addresses, and API activity. This can help analysts investigate the scope of suspicious behavior and identify relationships that may not be obvious from a single alert. Detective works particularly well alongside GuardDuty and CloudTrail because security findings can provide an initial indication while Detective supplies additional investigative context for determining what occurred.

Question 47

Which network design separates traffic entering or leaving an environment from traffic moving between internal workloads?

1. East-west and north-south segmentation
2. Shared DNS resolution
3. Centralized password management
4. Application logging

Correct Answer: 1

Explanation

North-south traffic generally describes communication entering or leaving an environment, while east-west traffic describes communication between internal workloads. Security architectures can apply different controls to these traffic patterns. For example, AWS WAF and CloudFront may help protect internet-facing applications, while security groups, network ACLs, Network Firewall, and segmentation can restrict internal workload communication. Separating these traffic paths helps reduce unnecessary connectivity and can limit lateral movement after a compromise. Security requirements should determine the appropriate boundaries and inspection points.

Question 48

Which AWS service can help enforce a consistent set of security and compliance rules across multiple AWS accounts?

1. AWS Config conformance packs
2. Amazon CloudFront
3. AWS Shield
4. Amazon Route 53

Correct Answer: 1

Explanation

AWS Config conformance packs provide a collection of AWS Config rules and remediation actions that can be deployed to help evaluate compliance against defined requirements. They are useful for applying consistent configuration standards across multiple accounts and Regions. Security teams can use conformance packs to assess requirements such as encryption, logging, public exposure, and approved resource configurations. Centralized deployment and monitoring can improve governance in large AWS environments. Organizations should periodically review the rules to ensure that they continue to reflect current security and compliance requirements.

Question 49

Which IAM feature limits the maximum permissions that an IAM role or user can receive?

1. Permission boundary
2. Security group
3. Service-linked role
4. Resource tag

Correct Answer: 1

Explanation

An IAM permissions boundary defines the maximum permissions that an IAM user or role can have. It does not directly grant permissions; instead, it acts as a guardrail that limits the effective permissions that identity-based policies can provide. Permission boundaries are useful in delegated administration scenarios where developers or teams need to create roles but should not be able to grant unrestricted privileges. Effective access still depends on other policy types and AWS authorization rules. Organizations should combine boundaries with SCPs and least-privilege policies when appropriate.

Question 50

A security administrator wants to prevent a delegated administrator from creating IAM roles with permissions outside an approved scope. Which combination is most useful?

1. Permission boundaries and IAM policies
2. S3 lifecycle rules and CloudFront
3. Route 53 and AWS WAF
4. CloudWatch dashboards and alarms

Correct Answer: 1

Explanation

Permission boundaries can restrict the maximum permissions that delegated administrators can assign to roles they create, while IAM policies define the permissions available to the roles. This combination supports controlled delegation by preventing administrators from creating identities that exceed an approved permission boundary. In multi-account environments, service control policies can provide an additional organization-level guardrail. Security teams should carefully design and test the policies because effective permissions result from the interaction of multiple policy types and explicit denies.

Question 51

Which AWS service can provide a private certificate authority for issuing certificates to internal applications?

1. AWS Private Certificate Authority
2. Amazon GuardDuty
3. AWS Security Hub
4. Amazon Detective

Correct Answer: 1

Explanation

AWS Private Certificate Authority provides a managed private certificate authority that organizations can use to issue certificates for internal applications, services, devices, and workloads. It can support private PKI requirements without requiring an organization to operate its own certificate authority infrastructure. Security teams must still manage certificate templates, trust relationships, issuance permissions, renewal, revocation, and private CA protection. Private certificates are useful when services need authenticated encrypted communication but should not use publicly trusted certificates.

Question 52

A company needs to ensure that a database connection from an application uses an encrypted protocol. Which security control should be applied?

1. Enforce TLS for the connection
2. Disable database authentication
3. Use public IP addresses
4. Remove network segmentation

Correct Answer: 1

Explanation

Enforcing TLS protects data transmitted between the application and database from interception and unauthorized modification. The exact configuration depends on the database technology and AWS service involved, but the goal is to require encrypted communication and appropriate certificate validation. Organizations should use supported modern TLS configurations and avoid weak protocols or unnecessary exceptions. Encryption in transit should be combined with strong authentication, network restrictions, least-privilege database permissions, and monitoring. Simply placing systems inside a private network does not replace encryption when sensitive data crosses network connections.

Question 53

Which Amazon S3 feature can help prevent objects from being deleted or overwritten during a defined retention period?

1. S3 Object Lock
2. S3 Transfer Acceleration
3. S3 Inventory
4. S3 Select

Correct Answer: 1

Explanation

S3 Object Lock provides write-once-read-many capabilities that can help protect objects from deletion or modification during a defined retention period. This is useful for protecting backups, audit records, and other data that must remain immutable for security or compliance purposes. Object Lock supports retention configurations and legal holds. Organizations should carefully select retention requirements and understand the operational consequences because protected objects may not be removable before the applicable restrictions expire. Object Lock can strengthen resilience against accidental deletion and certain ransomware-related attacks.

Question 54

Which AWS service helps identify sensitive data stored in Amazon S3 and can provide findings about potential data exposure?

1. Amazon Macie
2. AWS Shield
3. Amazon Inspector
4. AWS Firewall Manager

Correct Answer: 1

Explanation

Amazon Macie uses automated discovery and classification capabilities to identify sensitive data in Amazon S3. It can identify categories of sensitive information and provide findings that help security teams investigate potentially risky storage configurations or data exposure. Macie is particularly useful for organizations that need visibility into where sensitive information is stored. Security teams can combine Macie findings with S3 access controls, encryption, logging, and data classification policies. Sensitive-data discovery should be performed continuously because new objects and data sources can appear over time.

Question 55

Which AWS service can provide centralized storage and analysis of security data using the Open Cybersecurity Schema Framework?

1. Amazon Security Lake
2. AWS KMS
3. AWS Secrets Manager
4. Amazon Inspector

Correct Answer: 1

Explanation

Amazon Security Lake is designed to centralize security data from AWS, third-party sources, SaaS applications, and other environments. It uses the Open Cybersecurity Schema Framework to normalize security information, which can make data from different sources easier to analyze consistently. Security teams can use this centralized security data for investigation, threat hunting, and analytics. Security Lake complements services such as Security Hub and GuardDuty by providing a broader security-data repository. Proper access controls, retention policies, and data lifecycle management remain important.

Question 56

Which AWS capability can help determine whether a security finding from GuardDuty represents a broader compromise?

1. Validate the finding using related CloudTrail and Detective evidence
2. Immediately delete the finding
3. Disable GuardDuty
4. Remove all IAM policies

Correct Answer: 1

Explanation

A GuardDuty finding should be validated using additional evidence before determining the scope and impact of an event. Analysts can review CloudTrail activity and use Amazon Detective to examine relationships among affected identities, resources, IP addresses, and actions. Additional application and network logs may also provide useful context. Validation helps distinguish genuine compromises from benign or expected activity and supports appropriate containment decisions. This process is especially important because automated findings provide indicators, but investigators need broader evidence to understand the actual incident.

Question 57

Which AWS service can provide centralized protection against DDoS attacks with enhanced visibility and response capabilities for critical applications?

1. AWS Shield Advanced
2. AWS Config
3. Amazon Macie
4. AWS Audit Manager

Correct Answer: 1

Explanation

AWS Shield Advanced provides enhanced DDoS protection capabilities for supported AWS resources and is intended for workloads with stronger protection requirements. It provides additional visibility and features beyond the baseline protections available through Shield Standard. Organizations can combine Shield Advanced with services such as AWS WAF and Amazon CloudFront to create layered edge protection. Security teams should also design applications for resilience because DDoS protection is one component of availability planning. Monitoring, response procedures, and appropriate resource configuration remain important.

Question 58

Which AWS networking option provides an encrypted connection between an on-premises network and an Amazon VPC over the internet?

1. AWS Site-to-Site VPN
2. AWS Direct Connect only
3. Amazon CloudFront
4. AWS Private Certificate Authority

Correct Answer: 1

Explanation

AWS Site-to-Site VPN creates encrypted tunnels between an on-premises network and an Amazon VPC over the internet. It can provide secure connectivity for hybrid environments without requiring the organization to use an unencrypted public path for private traffic. Security teams should configure appropriate tunnel settings, routing, authentication, and monitoring. AWS Direct Connect provides dedicated connectivity but does not inherently encrypt traffic; additional encryption such as MACsec or VPN may be required depending on the architecture and security requirements.

Question 59

Which AWS feature can help require that a workload’s IAM role be used only from an approved AWS account or principal context?

1. IAM policy conditions
2. S3 lifecycle configuration
3. CloudFront cache behavior
4. Network ACL logging

Correct Answer: 1

Explanation

IAM policy conditions can evaluate contextual attributes of requests and help restrict how permissions are used. Depending on the scenario, condition keys can restrict access based on principal attributes, source account information, external identifiers, requested resources, or other supported context. This can be particularly useful when granting access between AWS accounts or protecting resources from unintended role usage. Security teams should select condition keys carefully and test cross-account authorization because an overly restrictive condition can prevent legitimate service operations.

Question 60

Which AWS service can centrally manage security-related findings from services such as GuardDuty, Inspector, and Macie?

1. AWS Security Hub
2. AWS Systems Manager
3. Amazon Route 53
4. AWS Certificate Manager

Correct Answer: 1

Explanation

AWS Security Hub provides a centralized location for aggregating, normalizing, and managing security findings from supported AWS security services and integrated third-party products. By bringing findings together, security teams can prioritize issues, investigate related risks, and integrate findings with automated remediation workflows. Security Hub can also help assess security posture against supported standards. It does not replace the underlying detection services; instead, it provides centralized visibility and management. Organizations should configure appropriate integrations, permissions, automation, and workflows based on their security operations requirements.
