Comprehensive and Detailed Explanation From Cisco SP Cloud Network Infrastructure Security Knowledge

Cloud security compliance frameworks (such as ISO 27001, PCI-DSS, GDPR, SOC 2, HIPAA) require:

Evidence of security events

Retention of logs for audit periods

Ability to generate compliance reports

Traceability and accountability

Incident investigation support

Effective log management enables:

Centralized collection of application, network, and system logs

Storage of logs for mandated retention periods

Generation ofaudit-ready reports

Documentation required for compliance assessments

Demonstration that monitoring and security controls are active and functioning

Therefore, the role of log management in regulatory compliance is primarily aboutdocumentation, traceability, auditing, and reporting, which aligns only with Option A.

The other options do not directly serve regulatory compliance requirements:

Brelates to resource optimization, not compliance.

Crefers to interoperability, which is unrelated to regulatory auditing.

Dimproves security but does not directly address compliance documentation.
