Explanation:
To maintain operational assurance, organizations use two basic methods: system audits and monitoring.
Monitoring refers to an ongoing activity whereas audits are one-time or periodic events and can be either
internal or external. The essential difference between a self-audit and an independent audit is objectivity, thus
indirectly affecting the results of the audit.
Incorrect Answers:
A: Internal and external auditors can use the same tools.
B: Internal and external auditors should return the same results. However, the objectivity of an independent
audit may return more comprehensive results.
D: Internal and external auditors should have the same level of competence.
