12. Describe Problem Management.
Problem Management identifies and resolves the root causes of incidents to prevent recurrence. It includes problem identification, root cause analysis, and resolution implementation.
13. What is Change Management?
Change Management controls changes to IT services and infrastructure, minimizing service disruption. It includes evaluating, approving, and implementing changes.
14. Explain the concept of a Service Level Agreement (SLA).
An SLA is a formal agreement between a service provider and a customer, defining the expected service levels, performance metrics, and responsibilities.
15. What is Configuration Management?
Configuration Management tracks and controls IT assets and configurations. It ensures the integrity of assets and configurations throughout their lifecycle.
16. How does ITIL handle risk management?
ITIL integrates risk management into its processes by identifying, assessing, and mitigating risks to service delivery and IT operations.
17. What is the role of the Service Desk?

20. What is Availability Management?
Availability Management ensures IT services are available as agreed in SLAs, focusing on reliability, maintainability, and serviceability.
21. What is the purpose of Release Management?
Release Management controls the deployment of software and hardware components into the production environment, ensuring changes are delivered smoothly.
22. Describe Service Continuity Management.
Service Continuity Management ensures that IT services can continue in the event of a disaster or major incident.
23. What is Information Security Management?
Information Security Management protects IT assets and data from security threats, ensuring confidentiality, integrity, and availability.
