The answer is to add a higher priority allow rule for those specific IPs. This works because Cloud Armor security policies evaluate rules in order of priority, with lower numbers taking precedence; a higher priority (lower number) allow rule will match the legitimate traffic before the blocking rule can deny it, effectively overriding the block for those sources while leaving the rest of the security policy intact. On the Google Professional Cloud Security Engineer exam, this scenario tests your understanding of rule priority and the distinction between overriding versus removing protections—a common trap is to delete the blocking rule or lower its priority, which would expose the backend to attacks. Remember the memory tip: “Priority is king—a high-priority allow beats a low-priority deny.” This approach preserves the security posture while quickly restoring access for the affected IPs.
PCSE Practice Question: Managing operations in a cloud solution environment
This PCSE practice question tests your understanding of managing operations in a cloud solution environment. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
Your organization uses Cloud Armor to protect against web attacks. After a change to the security policy, legitimate traffic from certain IPs is being blocked. You need to quickly allow that traffic while preserving the security policy. What should you do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Add a higher priority allow rule for those IPs
Adding a higher priority allow rule for the affected IPs allows the traffic without removing the security policy. Other options either remove protection or are ineffective.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Remove the offending rule from the security policy
Why it's wrong here
Removing the rule weakens security and may expose other traffic.
✗
Enable logging on the security policy
Why it's wrong here
Logging provides visibility but does not change the blocking behavior.
✗
Set the security policy to preview mode
Why it's wrong here
Preview mode disables enforcement entirely, not just for specific IPs.
✓
Add a higher priority allow rule for those IPs
Why this is correct
A higher priority rule explicitly allows the traffic before the blocking rule is evaluated.

Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
