For a high-level National Security Officer, the following education and qualifications would most likely be needed:
- Leadership skills: Essential for managing teams and making critical decisions in high-pressure situations.
- Bachelor's degree: Typically required for advanced positions, often in fields such as national security, international relations, political science, or related areas.
- Discipline: Important for maintaining ethical standards and adherence to protocols in national security operations.
The other options, design skills and customer-service skills, are generally not primary requirements for this role. A high school degree may be a minimum requirement but would not be sufficient for a high-level position. Therefore, it wouldn't be checked as applicable for a high-level officer.
