Quick Answer
The answer is probability, impact, and response strategy. These three required items in a risk register are essential because probability and impact are multiplied together to calculate the risk score, which determines the priority of each risk and drives resource allocation for response planning. The response strategy is equally mandatory, as it documents the specific approach—such as avoid, mitigate, transfer, or accept—that the team will take to manage the risk proactively. On the CompTIA Project+ PK0-005 exam, this concept tests your understanding of the risk register’s core structure under the risk management domain; a common trap is omitting the response strategy, since many candidates mistakenly list only probability and impact. Remember the mnemonic “PIR” (Probability, Impact, Response) to recall the three required fields every time you see a risk register question.
This PK0-005 practice question tests your understanding of tools and documentation. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A project manager is conducting a risk assessment workshop. Which THREE items should be included in the risk register for each identified risk?
Impact
Impact is a standard field.
Root cause analysis
Why wrong: Root cause analysis is a technique, not a register entry.
Risk category
Why wrong: Risk category is not typically an entry; risks are categorized but not as a field per risk.
Probability
Probability is a standard field in risk register.
Response strategy
Response strategy is a standard field.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Impact
The risk register must capture the probability and impact of each risk to calculate its risk score (Probability × Impact), which prioritizes risks for response planning. The response strategy is also required because it documents how the risk will be managed, ensuring proactive mitigation. These three elements are standard components of a risk register per PMI best practices.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
CompTIA often tests the distinction between mandatory risk register fields (probability, impact, response strategy) and optional or derived elements (root cause analysis, risk category), leading candidates to include extra items that are not required for every risk entry.
Detailed technical explanation
The risk register is a living document that evolves throughout the project; for each risk, the probability and impact are typically rated on a scale (e.g., 1–5) to compute a risk score, which drives prioritization. The response strategy (e.g., avoid, mitigate, transfer, accept) is documented after risk response planning, ensuring the risk has an actionable plan. In practice, the risk register also includes fields like risk ID, description, owner, and status, but the question specifically asks for the three items that must be included for each identified risk.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the PK0-005 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
