PMI-RMP Specialized Risk Analyses — 25 Questions

Question 1

In a decision tree analysis, what occurs if you 'fold back' the decision tree?

Accepted Answer

You determine the optimal path by selecting the branch with the best EMV at each decision node.. Folding back involves calculating the EMV for each chance node and choosing the alternative at each decision node that maximizes the expected value (or minimizes cost).

Answer

You reset the probabilities of all chance nodes to zero.

Answer

You assign risk scores to each decision alternative.

Answer

You calculate the probability of each branch ending in failure.

Question 2

You are conducting sensitivity analysis using a scatter plot in a simulation tool. What does a tight clustering of data points along a diagonal line suggest?

Accepted Answer

High sensitivity.. A tight clustering along a line indicates a high linear correlation between the input variable (e.g., activity duration) and the output (e.g., project finish date).

Answer

The variable is independent of the outcome.

Answer

Low sensitivity.

Answer

The simulation failed to converge.

Question 3

In the context of risk-adjusted cost analysis, what is the primary purpose of adding a 'Risk Contingency' reserve to the project budget?

Accepted Answer

To cover identified risks that have been quantified.. Contingency reserves are specifically for 'known-unknowns' identified during the risk assessment process.

Answer

To cover scope creep requested by the client.

Answer

To account for inflation over the project lifecycle.

Answer

To replace the management reserve.

Question 4

During a Monte Carlo simulation in @RISK, you notice the project completion date distribution is heavily skewed. Which distribution type is most appropriate for modeling task durations that have a hard 'minimum' but a long 'maximum' tail?

Accepted Answer

Beta distribution.. A PERT or Triangular distribution is often used, but a Beta distribution is generally preferred for modeling skewed task durations with defined minimum, mode, and maximum values.

Answer

Normal distribution.

Answer

Discrete distribution.

Answer

Uniform distribution.

Question 5

When evaluating project risks using EMV, why is it critical to include both threats and opportunities in the calculation?

Accepted Answer

To provide an accurate assessment of the project's risk exposure.. EMV calculates the net risk exposure by netting out positive and negative impacts, providing a realistic estimate of the project's risk profile.

Answer

To double the number of items in the Risk Register.

Answer

To ensure the contingency reserve is maximized.

Answer

To satisfy regulatory reporting requirements.

Question 6

When utilizing a tornado diagram in Oracle Primavera Risk Analysis to conduct sensitivity analysis, which metric indicates the highest impact on the project finish date?

Accepted Answer

The activity with the largest positive correlation coefficient.. The tornado diagram displays the correlation coefficient between activity duration and the project completion date. Higher correlation indicates greater sensitivity.

Answer

The activity with the highest 'Float' value.

Answer

The activity with the lowest baseline duration.

Answer

The activity with the most resource assignments.

Question 7

You are analyzing a decision tree in a project management software. A node shows a probability of 0.3 for a failure costing $100k, and 0.7 for success costing $20k. If the decision to proceed costs $10k, what is the correct Expected Monetary Value (EMV)?

Accepted Answer

$54,000. EMV = (Probability * Cost) + Decision Cost. (0.3 * 100,000) + (0.7 * 20,000) + 10,000 = 30,000 + 14,000 + 10,000 = 54,000.

Answer

$44,000

Answer

$60,000

Answer

$34,000

Question 8

You are performing a Monte Carlo simulation in Primavera Risk Analysis. To ensure the simulation captures the uncertainty in activity durations accurately, which setting should you verify in the 'Risk Options' menu?

Accepted Answer

The 'Iteration count' is set to a statistically significant number such as 1,000 or greater.. In Primavera Risk Analysis, the 'Risk Options' dialog allows you to define the convergence criteria and iteration counts. Setting the iteration count too low prevents the simulation from reaching a stable confidence level.

Answer

The 'Risk Threshold' is set to zero for all activities.

Answer

The 'Resource Calendar' is disabled.

Answer

The 'Baseline Project' is set to read-only mode.

Question 9

When configuring a simulation in Oracle Primavera Risk Analysis, what is the impact of checking the 'Correlate Task Durations' option?

Accepted Answer

It enables the model to reflect that specific tasks may fluctuate together.. Correlating task durations allows the user to link the uncertainty of one task to another, reflecting real-world dependencies where a delay in one area often leads to delays in related areas.

Answer

It reduces the number of iterations required for convergence.

Answer

It forces all tasks to have the same duration.

Answer

It automatically removes all risk events from the schedule.

Question 10

Which document is the primary input for identifying risks to be included in a quantitative risk analysis?

Accepted Answer

Risk Register.. The Risk Register, developed during the Qualitative Risk Analysis phase, identifies the risks that are prioritized for further quantitative study.

Answer

Stakeholder Engagement Plan.

Answer

Lessons Learned Repository.

Answer

Project Charter.

Question 11

You are reviewing a S-curve generated from a cost simulation. What does the P80 value represent on this curve?

Accepted Answer

The cost level with an 80% confidence of being met or bettered.. The P80 value on a cumulative probability distribution (S-curve) indicates that there is an 80% probability that the project cost will be at or below that value.

Answer

The average cost of the project.

Answer

The cost value representing the 20th percentile of risks.

Answer

The baseline cost before risk adjustments.

Question 12

You are performing a risk-adjusted schedule analysis using a 'Correlation Coefficient' between two tasks. What does a value of -0.8 indicate?

Accepted Answer

As one task duration increases, the other tends to decrease.. A strong negative correlation (-0.8) means that as the duration of one task increases, the duration of the other tends to decrease significantly.

Answer

The two tasks are perfectly independent.

Answer

The correlation is too weak to be significant.

Answer

The tasks will always finish at the same time.

Question 13

Which of the following is an advantage of using a Monte Carlo simulation over a static schedule analysis?

Accepted Answer

It accounts for the variability of multiple tasks simultaneously.. Static analysis only considers the 'most likely' duration, ignoring the range of uncertainty present in all real-world projects.

Answer

It provides a single, definitive project completion date.

Answer

It requires less data to perform than static analysis.

Answer

It completely removes the need for expert judgment.

Question 14

In Risk-Adjusted schedule analysis, what is the primary difference between a 'Risk Event' and 'Uncertainty' (duration variability)?

Accepted Answer

Uncertainty affects all tasks, while risk events have a probability of occurrence.. Uncertainty is inherent to every task (e.g., estimation variance), while risk events are specific, discrete occurrences that may or may not happen (e.g., severe weather).

Answer

Risk events are modeled with triangular distributions.

Answer

Risk events are always more expensive than uncertainty.

Answer

Uncertainty can be mitigated, but risk events cannot.

Question 15

When modeling a risk event that might happen multiple times (e.g., machine breakdowns), what is the most appropriate technique in a simulation?

Accepted Answer

Use frequency modeling (Poisson or similar distribution).. Frequency modeling allows the user to define the number of occurrences for a risk within the simulation period.

Answer

Increase the task duration by the total estimated impact.

Answer

Assign a fixed date for each occurrence.

Answer

Delete the task and recreate it as multiple tasks.

Question 16

You are reviewing a Monte Carlo simulation result. The histogram shows a bimodal distribution for the project completion date. What does this likely suggest about your model?

Accepted Answer

The model contains a high-impact conditional branch.. A bimodal distribution suggests two distinct likely outcomes, often caused by a 'conditional' logic path or a major risk event that, if it occurs, significantly shifts the project path.

Answer

The input distributions are all Normal.

Answer

The simulation count is too low.

Answer

The project is guaranteed to finish on time.

Question 17

You are adjusting the logic of your schedule to include a 'probabilistic branch'. What does this allow you to do in a risk analysis simulation?

Accepted Answer

Model the occurrence of specific, mutually exclusive project outcomes.. Probabilistic branching allows the simulation to choose between different paths based on defined probabilities, simulating scenarios like 'rework required' or 'testing passes vs fails'.

Answer

Automatically assign risk owners.

Answer

Increase the precision of activity estimates.

Answer

Delete non-critical path activities.

Question 18

What is the primary output of a sensitivity analysis in a project risk assessment?

Accepted Answer

Identification of the most influential project variables.. Sensitivity analysis identifies which variables have the most significant impact on project objectives, allowing teams to focus on critical risks.

Answer

A total project cost estimate.

Answer

A project management plan.

Answer

A list of all possible project risks.

Question 19

When calculating the Expected Monetary Value (EMV) for a risk, why do we multiply probability by impact?

Accepted Answer

To determine the risk-weighted value of the impact.. This provides the 'weighted' value of the risk, which is the standard methodology for normalizing risk impact across different types of potential events.

Answer

To create a buffer for the management reserve.

Answer

To identify which risks are impossible to mitigate.

Answer

To calculate the total cost of all risks combined.

Question 20

When running a Monte Carlo simulation, you find that the results do not change between runs. What is the most likely cause?

Accepted Answer

The random seed is fixed.. If the results are identical, the simulation is likely using the same 'Random Seed'. Changing the seed ensures that each run uses a different sequence of random numbers.

Answer

The iteration count is too high.

Answer

The project file is corrupted.

Answer

All risks have a probability of 100%.
