Which action should you perform first to meet the security operations requirements?

Upgrading the pricing tier of Security Center to Standard is the first step because it unlocks advanced threat protection capabilities, security analytics, and regulatory compliance features crucial for robust security operations. Without the Standard tier, many essential security features, like Just-in-Time VM access, adaptive application controls, and advanced threat detection, are unavailable. Turning on Auto Provisioning is important but only effective after the Standard tier enables the agents. Integrating Security Center and Microsoft Cloud App Security provides enhanced visibility for SaaS applications but isn't the foundational first step for overall Azure resource security. Modifying the workspace configuration might be necessary later but won't enable the core security features provided by the Standard tier.
