CORB LATEST EXAM TEST 2026/2027 QUESTIONS AND
SOLUTIONS RATED A+
✔✔It drives contract type decisions and which clauses are to be used. - ✔✔Why is the
commerciality determination important?
✔✔FAR 12.207:
- Firm-Fixed-Price (FFP)
- Fixed-Price with Economic Price Adjustment (FP-EPA)
- Time-and-Materials (T&M)
Labor-Hour (LH)
Any type of cost contracts or CLINs are prohibited. - ✔✔When acquiring commercial
items, what contract type(s) are normally used? What type(s) are prohibited?
✔✔Combined synopsis/solicitation procedure combines the synopsis required by 5.203
and the issuance of the solicitation into a single document. When using the combined
synopsis/solicitation procedure, the SF 1449 is not used for issuing the solicitation.
Synopsis prepared as described at 5.207. - ✔✔Under FAR 12.603, when a written
solicitation will be issued, the contracting officer may use what procedure to reduce the
time required to solicit and award contracts for the acquisition of commercial items?
✔✔Ensure market research has been conducted seeking out alternative sources. If the
procurement is greater than the SAT, a J&A is required. Review the J&A thoroughly. If
under the SAT a limited source justification will be required. - ✔✔Your customer has
submitted a requirement and states that only one source can meet their requirements.
Describe your process/steps that you will take in evaluating, processing and approving
or rejecting a sole source acquisition? Discuss any differences in the process based on
different threshold levels.
✔✔When a customer requests a sole/limited source due to urgency, I first validate the
bona fide need, funding, and whether the urgency is legitimate—not caused by lack of
advance planning (FAR 6.301). I determine the estimated value and applicable
procedures (Part 13, 14/15, or 16.505). If unusual and compelling urgency exists, I use
FAR 6.302-2 and prepare a J&A documenting the serious injury, market research, and
efforts to solicit as many sources as practicable. Synopsis and response times may be
shortened or waived under FAR 5.202, but competition is limited only to the extent
necessary, approvals follow FAR 6.304, and price must still be fair and reasonable. -
✔✔Your customer has submitted an urgent requirement and believes that we should
limit the number of sources or go to only one source.
Describe your process/steps that you will take in validating the urgency and either
processing and approving a sole source/limited source J&A or denying it.
Address any leniencies associated with urgency (synopsis, posting, etc.) if any.
, ✔✔Benefits of competition:
- drives cost savings
- improves quality of product/service
- enhances solutions and the industrial base
- 4) promotes fairness and openness leading to public trust
- 5) prevents waste, fraud, and abuse, because KTR's know they must perform at a high
level or else be replaced
- 6) increases likelihood of efficiencies and innovations
Barriers to competition:
- Urgency
- Restrictive Requirements
- Incumbency Advantage
- Limited Market Base
- Poor Planning
- Funding Constraints
- Security/Classified Work - ✔✔What are some of the benefits of competition?
What are some barriers to competition?
✔✔Inadequacies: Poorly defined requirement, too restrictive specifications (i.e. brand
name), proprietary technology, lack of market research, customer loyalty (i.e., RA happy
with current contractor). - ✔✔What Government inadequacies or mistakes in the
specifications/PWS could cause a lack of competition?
✔✔Contracting in contingency environments requires rapid response and flexibility.
Challenges include: 1) Lack of local vendor base, 2) Communication/infrastructure
gaps, 3) High turnover of personnel, 4) Security/Safety of personnel. Resolve by using
local sources, streamlined procedures, and frequent COR interaction. - ✔✔What is your
experience in awarding and administering contingency contracts as a Contracting
Officer or Contract Specialist? What were your 2 to 4 biggest challenges experienced
and how did you resolve or mitigate the challenges?
✔✔A COR is an individual designated in writing by the Contracting Officer (CO) to
provide technical monitoring and surveillance of a contract. The COR serves as a
subject matter expert and ensures goods and services meet contract requirements and
acceptance standards. CORs are nominated by the requiring activity as early as
practicable in the acquisition process. For DoD, a COR must be designated for all
service contracts, both firm-fixed-price and other-than-fixed-price. Surveillance is
tailored to the contract's dollar value and complexity. - ✔✔What is a Contracting
Officer's Representative (COR) and what are their primary responsibilities?
✔✔A COR may monitor performance, review deliverables, and document contractor
compliance. However, a COR has no authority to change contract price, cost, fee,
