, COR 106 Exam Guide 2026: Questions, Answers & Explanations
1. Which type of service contracting is generally the least preferred method for the Government to
utilize?
a. Multi-year contracting
b. Time-and-materials contracting
c. Firm-fixed-price contracting
d. Cost-reimbursement contracting
Answer: b. Time-and-materials contracting
Explanation: Time-and-materials contracts provide the least certainty to the Government
regarding final costs, as payment is based on direct labor hours at fixed hourly rates and the
actual cost of materials. This lack of cost control makes it the least preferred method when other
contract types are suitable.
2. Bilateral modifications are primarily used to:
a. Issue administrative changes.
b. Make negotiated equitable adjustments and definitize change orders.
c. Unilaterally compel contractor action.
d. Terminate a contract for convenience.
Answer: b. Make negotiated equitable adjustments and definitize change orders.
Explanation: A bilateral modification is a contract amendment signed by both the Government
and the contractor. It is the appropriate instrument for formally incorporating a mutually agreed-
upon change, such as an equitable adjustment for unforeseen work or definitizing a preliminary
change order.
3. The Contracting Officer's Representative (COR) is authorized to:
a. Modify contract terms and conditions.
b. Obligate Government funds.
c. Provide technical direction within the scope of the contract.
d. Accept final deliverables on behalf of the Government.
Answer: c. Provide technical direction within the scope of the contract.
, Explanation: The COR's authority is strictly limited to providing technical guidance and
monitoring performance as detailed in their designation letter. They cannot change any term,
condition, cost, or deliverable of the contract; only the Contracting Officer holds that authority.
4. Which individual possesses the expressed legal authority to enter into and administer contracts
and is responsible for ensuring compliance with all applicable laws and regulations?
a. Program Manager
b. Contracting Officer
c. Contracting Officer's Representative
d. Legal Counsel
Answer: b. Contracting Officer
Explanation: The Contracting Officer is the only individual with the warrant—a certificate of
appointment granting express authority—to bind the Government in a contractual agreement.
They bear the ultimate responsibility for the contract's legality and execution.
5. A COR provides technical direction to a contractor that leads to a change in the delivery
schedule and an increase in cost. Is this action within the COR's scope of authority?
a. True
b. False
Answer: b. False
Explanation: Any technical direction that results in an increase in cost, a change to the delivery
schedule, or an alteration of the contract's scope exceeds the COR's authority. Such actions
constitute a contract modification, which must be issued solely by the Contracting Officer.
6. A contractor, with whom you have worked for three years on a five-year contract, offers you two
box tickets to a major sporting event. Can you accept this gift?
a. Yes, because it is a token of appreciation for a long-standing professional relationship.
b. Yes, if you pay the contractor for the face value of the tickets.
c. No, because the value almost certainly exceeds the minimal value threshold for gifts.
d. No, because accepting any gift from a contractor is strictly prohibited.
Answer: c. No, because the value almost certainly exceeds the minimal value threshold for gifts.
