CLTD Practice Questions with Answers and Explanations
Read this guide in Arabic: اقرأ بالعربية
The CLTD exam does not reward memorized definitions. Most questions put you inside a situation, give four options where two look sensible, and ask which decision is best. Candidates in our Riyadh and Dammam classes tell us that meeting this style in week one changed the way they studied.
Below are ten original scenario questions written by our trainers in the style of the exam, each with the answer and a short explanation. They are not ASCM items, since ASCM does not release live questions. Work through them honestly before you read the answers, then use the advice further down. For scoring and booking, see our CLTD exam guide for Saudi Arabia.
How CLTD questions are built
Almost every item has a distractor that would be right in a slightly different situation. The exam tests whether you spotted the constraint in the stem: fixed capacity, a service commitment, a cost that is already sunk, a lead time that is variable rather than long. Read the last sentence of the stem twice. That is usually where the constraint hides.
Practice questions 1 to 5
1. Logistics strategy and customer service
A distributor in Riyadh proposes upgrading every customer to next day delivery to improve service levels. What should guide the decision?
A. Match the fastest competitor regardless of cost
B. The point where the added logistics cost exceeds the value the service creates
C. The preference of the largest customer only
D. The capacity of the current fleet
Answer: B. Service and total logistics cost rise together, and past a certain level each extra point of service costs far more than it returns. Logistics strategy sets service targets by segment, not one standard for everybody.
2. Capacity planning and demand management
A beverage distributor in Jeddah faces a large, predictable demand spike every Ramadan. Warehouse and fleet capacity are fixed for this year. What is the most appropriate response?
A. Chase demand by adding capacity during the peak
B. Build inventory ahead of the peak using level production
C. Ration allocations during the peak
D. Increase the forecast interval to monthly
Answer: B. When capacity cannot flex and demand is predictable, you move the work earlier and hold the output as inventory. Chasing needs capacity you do not have, and rationing damages the customers you spent years winning.
3. Order management
An order arrives on the promised date, complete and undamaged, but the invoice shows the wrong price and has to be reissued. Does it count as a perfect order?
A. Yes, because the goods arrived on time and complete
B. Yes, because invoicing sits outside logistics
C. No, because documentation accuracy is part of the measure
D. Only if the customer complains
Answer: C. The perfect order measure requires on time, complete, damage free and correctly documented, including the invoice. It is a deliberately hard metric, which is why the score looks low the first time a company measures it.
4. Inventory management
A spare parts importer finds that supplier lead time variability has doubled while average lead time and demand are unchanged. To hold the same service level, safety stock should:
A. Stay the same, because average demand has not moved
B. Fall, because the average lead time is unchanged
C. Rise, because safety stock covers variability rather than the average
D. Be replaced by a larger order quantity
Answer: C. Safety stock is driven by the variability of demand during lead time and by the service level you choose, not by the average itself. This is the single most common error we see in our classes.
5. Warehouse management
In a distribution center near Dammam, travel accounts for most of the time spent on each pick. Which action gives the fastest improvement?
A. Add pickers on the shift
B. Reslot fast moving items close to the dispatch area
C. Buy additional forklifts
D. Increase safety stock on top sellers
Answer: B. Velocity based slotting attacks the travel itself, which is the actual cost. More labor and more equipment increase the cost of a process you have not yet fixed.
Practice questions 6 to 10
6. Transportation and mode selection
A critical spare is needed at a plant in Jubail where every day of downtime is extremely expensive. Sea freight takes weeks, air freight days at many times the freight cost. What is the correct basis for choosing?
A. Lowest freight cost per kilogram
B. Total cost including downtime and inventory carrying cost
C. The mode used for previous shipments
D. Whichever mode the freight forwarder recommends
Answer: B. Mode selection is a total cost decision, and for high value or urgent items the cost of not having the part dwarfs the freight bill. Cheap freight on the wrong shipment is expensive.
7. Global logistics and Incoterms
A Saudi importer buys goods CIF Jeddah under Incoterms 2020. Where does risk pass to the buyer?
A. When the goods are cleared through Saudi customs
B. When the goods are delivered to the buyer's warehouse
C. When the goods are loaded on board the vessel at the origin port
D. When the vessel arrives at Jeddah
Answer: C. Under CIF the seller pays carriage and insurance to the named destination port, but risk transfers on loading at origin. Cost point and risk point are different, and exam questions rely on candidates confusing the two.
8. Logistics network design
A company operating two distribution centers plans to move to eight, holding demand and service level constant. Using the square root law, system safety stock will roughly:
A. Stay the same
B. Double
C. Quadruple
D. Halve
Answer: B. The square root of eight divided by two is two, so safety stock roughly doubles. More stocking points cut outbound transport and delivery time but pull inventory up, which is the core trade off in network design.
9. Reverse logistics
An online retailer in Riyadh finds that many returns arriving at its facility should never have been authorized. What is the most effective first control?
A. Expand the returns processing area
B. Apply gatekeeping at the point of return authorization
C. Outsource disposal to a third party
D. Refund customers faster
Answer: B. Gatekeeping screens returns before they enter the reverse flow, which is far cheaper than handling them after arrival. Everything else in the list processes a cost you could have avoided.
10. Transportation cost management
A shipper sends five small shipments from Jeddah to Riyadh each week on a less than truckload basis. Which change reduces cost the most?
A. Renegotiate the less than truckload rate
B. Consolidate the shipments into one scheduled full truckload departure
C. Switch to air freight for the urgent items
D. Open a small warehouse in Riyadh
Answer: B. Consolidation moves the same freight at a much lower cost per unit by using the full vehicle. The price is a slightly longer order cycle, which most customers accept if the schedule is reliable.
How to use practice questions properly
Score alone tells you very little. What matters is the reason each wrong option was wrong, so read the explanation for all four choices, not only the one you picked. Keep a short error log by module, and you will usually find two modules producing most of your losses.
Practice under the real clock. At 150 questions in 3.5 hours you have roughly 84 seconds per question, which sounds generous until you meet three calculation items in a row. Sit at least two full length timed sets before exam day. Our CLTD study plan for a first attempt sets out when to schedule those.
Where to get full mock exams
The ASCM Learning System includes the closest thing to real practice, with module quizzes and a simulated exam, and it is the resource we tell candidates to exhaust first. Our CLTD training program adds trainer written question banks, timed mock sittings and a review session on the questions people miss most.
One warning. Sites selling real exam questions are selling either stolen content or nonsense, and using them puts your certification at risk. Candidates in our Riyadh CLTD classes who passed comfortably all did the same thing instead: hundreds of legitimate practice questions, reviewed slowly.
Frequently asked questions
Are these real CLTD exam questions?
No. ASCM does not publish live exam items, and anyone selling them is offering stolen or invented content. These questions were written by our trainers to match the style, difficulty and scenario format of the exam.
How many practice questions should I do before the CLTD exam?
Most of our candidates work through several hundred across the study period, spread across all nine modules rather than concentrated in your favorites. Volume matters less than review discipline. Two full length timed sets in the final fortnight are worth more than another hundred untimed questions.
What score on practice tests means I am ready?
As a rough guide, consistently scoring comfortably above the pass threshold on fresh timed questions, not on sets you have already seen, is a reasonable signal. The exam is scaled from 200 to 350 with 300 as the pass, so practice percentages never map exactly. Steady improvement across modules matters more than one good score.
Which CLTD modules produce the hardest questions?
In our classes the recurring trouble spots are inventory management, network design and the calculation items in transportation. They share a habit of asking for a trade off rather than a fact. Candidates who practice those three early usually stop losing marks elsewhere too.
