This CRISC practice question tests your understanding of it risk identification. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
An organization is migrating on-premises applications to a public cloud. Which THREE of the following should be considered as key risk identification activities?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Mapping network security group rules to existing firewall policies.
Mapping network security group (NSG) rules to existing firewall policies is a key risk identification activity because it ensures that security controls are correctly translated to the cloud environment. Misconfigured NSG rules can lead to unintended network exposure, such as open ports or overly permissive access, which directly increases the attack surface. This mapping identifies gaps between on-premises security postures and cloud-native security constructs, a critical step in risk identification during migration.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Identifying data residency and compliance requirements.
Why this is correct

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse financial analysis activities (like cost-benefit analysis or TCO) with risk identification, but CRISC focuses on identifying threats, vulnerabilities, and control gaps, not cost optimization.
Detailed technical explanation
How to think about this question
Network security groups (NSGs) in Azure, for example, operate at the subnet or NIC level with stateful filtering based on 5-tuple rules (source IP, source port, destination IP, destination port, protocol). A common subtlety is that default NSG rules allow all outbound traffic and deny all inbound traffic, but custom rules can inadvertently create asymmetric routing or bypass intended segmentation if not mapped precisely to existing firewall ACLs. In a real-world scenario, failing to map NSG rules to on-premises firewall policies can result in lateral movement risks where a compromised VM in a cloud VNet can access other VNets due to overly permissive NSG rules that were not aligned with the original firewall zone-based policies.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
