- A
Create a single custom rule with both geo-blocking and rate limiting conditions using CEL expressions, and enable preconfigured SQLi rules.
Why wrong: Rate limiting is a separate rule action ('rateBasedThrottle') and cannot be combined with other conditions in one rule.
- B
Create separate rules: one for geo-blocking with priority 500, one for rate limiting with priority 600, and enable preconfigured SQLi rules at priority 1000. Order them appropriately.
This is the correct approach: separate rules for different actions, with priorities ensuring evaluation order.
- C
Use Cloud Armor Managed Protection Plus, which automatically includes geo-blocking and rate limiting.
Why wrong: Managed Protection Plus provides adaptive protection and enhanced DDoS, but does not automatically configure geo-blocking or custom rate limits.
- D
Enable SQLi preconfigured rules only; geo-blocking and rate limiting are not supported in Cloud Armor.
Why wrong: Cloud Armor supports geo-blocking and rate limiting via custom rules.
PCSE Configuring Network Security Practice Question
This PCSE practice question tests your understanding of configuring network security. 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.
A company uses Cloud Armor security policies to protect their HTTP load balancer. They need to block requests from a specific geographic region (country X) and also limit requests from any IP to 1000 requests per second. They also want to use preconfigured rules for SQL injection prevention. What is the correct way to combine these requirements in a single security policy?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Create separate rules: one for geo-blocking with priority 500, one for rate limiting with priority 600, and enable preconfigured SQLi rules at priority 1000. Order them appropriately.
Cloud Armor rules are evaluated in order of priority (lowest number first). Preconfigured rules (like SQLi) have a priority of 1000 by default. Geographic and rate limiting rules can be added with custom priorities. The rule order matters: typically, you want to block/rate-limit before applying WAF rules to reduce processing. However, the question is about combining them correctly: all rule types can coexist in a single policy. The key is that each rule type has its own configuration; you can't set rate limiting in the same rule as geo-blocking; they must be separate rules.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
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.
Detailed technical explanation
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.
