DVA-C02 Security Practice Question
This DVA-C02 practice question tests your understanding of security. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A developer is designing a system that must meet PCI DSS compliance. Which THREE AWS services can help with logging and monitoring security events?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon CloudWatch Logs
Amazon CloudWatch Logs is correct because it provides a centralized service for collecting, monitoring, and storing log data from various AWS resources and applications. For PCI DSS compliance, CloudWatch Logs can ingest security-related logs (e.g., from EC2, Lambda, or on-premises servers) and enable real-time monitoring, metric filters, and alarms to detect and respond to security events. It also supports log retention policies and encryption at rest using AWS KMS, which are required for audit trails under PCI DSS Requirement 10.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse VPC Flow Logs (network metadata) with security event logging, or mistakenly think KMS is a logging service because it is used for encryption, but neither generates or monitors security events as required by PCI DSS.
Detailed technical explanation
How to think about this question
Under the hood, CloudWatch Logs uses log groups and log streams to organize ingested data, with support for real-time subscription filters that can forward logs to Amazon Elasticsearch Service or Lambda for advanced analysis. For PCI DSS, CloudWatch Logs can integrate with AWS CloudTrail to monitor API activity and with AWS Config to track resource configuration changes, forming a complete audit trail. A subtle behavior is that CloudWatch Logs does not automatically capture VPC Flow Logs or AWS Config data unless explicitly configured via subscriptions or metric filters.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
