The most appropriate action for an internal auditor who realizes that she has undertaken limited training and professional development is to accept responsibility for her own continuing professional development, develop a professional plan, and discuss it with the CAE. This proactive approach ensures that she meets the ongoing professional development requirements, aligns her training needs with the objectives of the internal audit activity, and maintains the necessary competencies to perform effectively in her role.References:

Given the chief audit executive's (CAE) new responsibility for the risk management and compliance operations, the independence of the internal audit activity could be compromised in future audits of these functions. Therefore, to maintain objectivity and impartiality, audits of risk management and compliance functions should ideally be overseen by a competent external assurance provider. This approach ensures that the audit is free from internal influence and bias, aligning with the IIA's standards on independence and objectivity.References: IIA Standard 1110 - Organizational Independence

The most accurate statement with respect to the required elements of the quality assurance and improvement program is that quality assessments focus on the internal audit activity's structure, relationships with stakeholders, compliance with the Standards, and internal audit staff proficiency. This description aligns with the IIA's standards on quality assurance, emphasizing the comprehensive scope of internal assessments, which are integral for ensuring the internal audit function operates effectively and adheres to professional standards.
