The answer is to investigate the data source of the KRI to ensure accuracy and timeliness. This is the correct first step because a KRI breach occurring while controls are reported as effective creates a logical contradiction—either the KRI data is flawed, or the control performance data is misleading. In risk management, data integrity must be validated before any operational response, as acting on inaccurate information can lead to wasted resources or overlooked threats. On the CRISC exam, this scenario tests your understanding of the “verify before act” principle, often appearing as a trap where candidates jump to adjust thresholds or enhance controls prematurely. A common memory tip is “KRI first, controls second”—always confirm the indicator’s reliability before questioning the control environment.
CRISC Risk and Control Monitoring and Reporting Practice Question
This CRISC practice question tests your understanding of risk and control monitoring and reporting. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 retail company monitors its key risk indicator (KRI) for credit card transaction fraud. The KRI has exceeded the established threshold for three consecutive days, but the weekly control performance report shows all fraud detection controls operating effectively. What should the risk practitioner do FIRST?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Investigate the data source of the KRI to ensure accuracy and timeliness.
Option A is correct because the discrepancy between the KRI and control performance indicates a potential data integrity issue or misalignment; verifying the KRI data source is the first step. Option B is wrong because adjusting the threshold without investigation could mask a real risk. Option C is wrong because enhancing controls before understanding the root cause may be premature. Option D is wrong because ignoring the KRI violates monitoring principles.
Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Immediately enhance the fraud detection controls.
Why it's wrong here
Controls appear effective per reports; enhancement is premature.
✗
Report the KRI breach to the board and recommend risk acceptance.
Why it's wrong here
Boards expect analysis before risk acceptance.
✗
Adjust the KRI threshold to align with current control performance.
Why it's wrong here
Adjusting thresholds without investigation may hide a genuine risk.
✓
Investigate the data source of the KRI to ensure accuracy and timeliness.
Why this is correct
Verifying data integrity is the logical first step before any other action.
Clue confirmation
The clue word "first" in the question point toward this answer.
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Detailed technical explanation
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
CIDR notation defines the prefix length.
Block size helps identify subnet boundaries.
Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
The required host count determines the smallest suitable subnet.
TExam Day Tips
→Write the block size before choosing the subnet.
→Check whether the question asks for hosts, subnets or a specific address range.
→Do not confuse /24, /25, /26 and /27 host counts.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Real-world example
How this comes up in practice
A network engineer segments a warehouse floor into three subnets: 20 scanners, 5 printers, and 2 management hosts. Picking the wrong mask wastes addresses or leaves too few usable hosts. Exam questions test whether you can apply CIDR notation, calculate block size, and identify the correct usable-host range for a given prefix.
What to study next
Got this wrong? Here's your next step.
Review block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related CRISC subnetting questions on CIDR, address ranges, and subnet selection.
