Ace the 2026 CDFM Challenge: Unleash Your Financial Defense Skills with Practice Exam 1!

The key idea is understanding the escalation path for unresolved DoD travel claims. When the Certifying Officer’s second review cannot resolve a doubtful travel claim, the next step is to forward it to the Defense Finance and Accounting Service (DFAS) for final determination. DFAS is the agency that handles DoD travel payments, audits vouchers, and settles disputed reimbursements, so they are the appropriate body to review and decide doubtful claims after internal DoD reviews. The other agencies listed don’t manage individual travel claim resolutions: GAO conducts audits, OMB handles budget and management policy, and SSA deals with Social Security matters.
