Amazon Web Services DOP-C02 Exam With Confidence Using Practice Dumps

Running unit tests in the build phase and aborting on failure (OnFailure=ABORT) prevents deployment if tests fail.

AWS CDK assertions module provides programmatic unit tests against synthesized templates (Option D).

The --rollback flag relates to CloudFormation stack rollback, not test gating.

The --require-approval flag controls manual approvals, not test outcomes.

cdk diff checks for changes but is not a unit test and may not catch logical errors.

Comprehensive and Detailed Explanation From Exact Extract:

The requirement is to restrict production deployments strictly to the pipeline, while still allowing emergency access to a specific engineer.

The best approach is to restrict the DevOps team to read-only access in production accounts, minimizing risk of manual changes (Option A).

The DevOps engineer can have an admin permission set but assume the pipeline IAM role for deployment, enforcing strict control.

Applying an SCP to deny modification by anyone other than the pipeline role enforces this at the organization level.Option B is similar but unnecessarily creates separate IAM users, increasing management overhead. Option C grants the DevOps engineer broader permissions that may conflict with controls. Option D complicates management with tagging and SCPs, increasing operational overhead.

The question focuses on detecting supply chain attacks that bypass CI/CD controls and result in malicious runtime behavior in the deployed serverless application. This requires runtime threat detection, not just static scanning or infrastructure validation.

Amazon GuardDuty is AWS’s managed threat detection service. GuardDuty now includes Lambda Protection, which analyzes Lambda function behavior, including network calls, IAM API usage, and other signals to detect compromised functions, crypto-mining, data exfiltration, and other malicious activity. GuardDuty automatically ingests CloudTrail, VPC Flow Logs (if enabled), and other telemetry without requiring code changes or agents. Findings are published and can be routed to Amazon EventBridge for near real-time notifications or automated remediation.

Option A (AWS WAF) only inspects HTTP requests to API Gateway and is focused on known bad patterns, not deeper behavioral anomalies. Option C (CloudFormation Guard) is focused on infrastructure-as-code validation in the pipeline, which explicitly does not help once malicious code is deployed. Option D (Network Firewall with Emerging Threats rules) protects VPC traffic, but serverless components like Lambda and API Gateway may not all traverse that firewall, and it is not targeted at function-level behavior.

Hence, enabling GuardDuty with Lambda Protection and using EventBridge notifications is the correct solution.
