Q4.

Zero days are a type of residual risk that can’t be eliminated.

True
False

Q5. What can you do to combat zero-days? (check all that apply)

Actively attack attackers back when they try to penetrate your systems
Follow best practices when designing systems
Design systems that can't have zero-days
Use defense-in-depth by compartmentalizing systems to limit impact
Monitor assets to identify abnormal patterns that might indicate attacks
Look to past exploits for insight and try to generalize previous solutions

Q6.

Risk probability theory can help quantify uncertainty and structure the decision making process.

True
False

Q7. In decision trees, the probability of all branches attached to a single event node always sums (adds) to 1.

True
False

Q8. Purely Pessimistic decision makers always minimize the maximum loss and maximize the minimum gain.

True
False

Q9. Risk preferences affect decision making and can influence valuation functions

True
False

Q11. Assume that a buyer has sufficient money and is looking to acquire as many apples as possible, assuming the apples are reasonably priced. The buyer gives you the valuation function above. Suppose that each option below is a leaf node attached to a choice node labeled "What to buy" on a two-attribute decision tree. Select the option below that is the most valuable choice for the buyer.

Buy 20 Apples from Vendor A at a Cost of $25 because I like vendor A
Buy 100 Apples from Vendor B at a Cost of $104 because they sell the most apples
Buy 30 Apples from Vendor C for $30 because they are the cheapest
Buy 40 Apples from Vendor D for $41 because they have more apples than Vendor C and are still pretty cheap.
Buy no apples because they are all too expensive
Buy apples only from A and B because their prices are under the value curve
Buy apples only from C and D because their prices are above the value curve
Buy all of the apples because the prices are reasonable and I want lots of them
