CAST Risk Management & Mitigation 5

Question 1

A team uses exploratory testing to uncover unknown risks in a newly integrated third-party API. This approach is MOST aligned with which risk management concept?

Accepted Answer

Unknown-unknown risk discovery

Answer

Exploratory testing is a key technique for surfacing unknown risks ('unknown-unknowns') that structured test cases cannot anticipate.

Question 2

Which of the following risk mitigation actions DIRECTLY reduces the IMPACT of a risk rather than its probability?

Accepted Answer

Implementing a rollback mechanism for failed deployments

Answer

A rollback mechanism limits the damage when a deployment fails without preventing the failure itself, directly reducing impact.

Question 3

During a sprint retrospective, the team notes that integration risks were consistently underestimated. Which improvement would MOST directly address this?

Accepted Answer

Include integration risk assessment as a formal step in sprint planning

Answer

Formalizing integration risk assessment during sprint planning ensures these risks are identified and mitigated before integration work begins.

Question 4

A risk is described as having a 30% probability of occurrence and an impact rating of 4 on a 5-point scale. What is its risk exposure value?

Accepted Answer

1.2

Answer

Risk exposure = Probability × Impact = 0.30 × 4 = 1.2, expressing the expected weighted impact of the risk.

Question 5

Which CAST testing principle states that testing effort should be concentrated where the probability and consequences of failure are greatest?

Accepted Answer

Risk-based testing

Answer

Risk-based testing is the principle of allocating more testing effort to areas with higher failure probability and higher consequence of failure.
