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 risk manager notices that a key risk indicator (KRI) for system downtime has exceeded the threshold for two consecutive months. What is the MOST appropriate immediate action?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Escalate to the risk owner for investigation.
Option C is correct because exceeding the KRI threshold indicates a potential risk increase, and the risk manager should escalate to the risk owner for investigation. Option A is wrong because updating the risk register alone does not address the immediate concern. Option B is wrong because revising the KRI threshold without understanding the cause may mask the issue. Option D is wrong because the KRI is already defined and monitored; changing it may not be appropriate.
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.
✗
Revise the KRI threshold to a higher value.
Why it's wrong here
Changing thresholds without analysis may hide emerging risks.
✗
Archive the current KRI and define a new one.
Why it's wrong here
Replacing the KRI is not appropriate; the existing metric is still relevant.
✗
Update the risk register with the new KRI value.
Why it's wrong here
Documentation alone does not address the risk increase.
✓
Escalate to the risk owner for investigation.
Why this is correct
The risk owner should assess the situation and determine corrective actions.
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.

Option A is wrong because updating the risk register alone does not address the immediate concern. Option B is wrong because revising the KRI threshold without understanding the cause may mask the issue. Option D is wrong because the KRI is already defined and monitored; changing it may not be appropriate.
