Comprehensive and Detailed Explanation From AWS Cloud Documentation:

The AWS Cloud Adoption Framework Operations perspective focuses on delivering cloud services at an agreed level and improving workload reliability through effective operations. AWS lists observability as an Operations capability because teams need metrics, logs, traces, endpoint monitoring, and alerts to understand workload health and identify problems. AWS also lists configuration management as an Operations capability because organizations need an accurate record of workloads, relationships, settings, and configuration changes, and must control configuration drift. Therefore, options A and E are correct. The other choices belong to different AWS CAF perspectives. Data governance is a Governance perspective capability concerned with authority, ownership, standards, quality, and control over organizational data. Platform architecture is a Platform perspective capability that establishes architectural guidelines, patterns, principles, and guardrails for the cloud environment. Portfolio management is a Business perspective capability that prioritizes cloud products and initiatives in line with strategy, value, and delivery capacity. The question asks specifically for Operations capabilities, so only observability and configuration management satisfy the AWS CAF classification.
