PCNE Implementing VPC Instances Practice Question
A company has deployed a Cloud Armor security policy with the following rules: Rule 1: allow from IP range 10.0.0.0/8 (priority 1000); Rule 2: deny from all (priority 2000). What will be the action for traffic from IP 10.1.1.1?
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
✓
Allow
Cloud Armor evaluates rules in priority order (lower number = higher priority). Rule 1 matches and allows the traffic, so Rule 2 is not evaluated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Deny
Why it's wrong here
The deny rule has lower priority (2000) and is only evaluated if no higher priority rule matches. Since the allow rule matches, deny is not applied.
- ✗
Error: conflicting rules
Why it's wrong here
There is no conflict; rules are evaluated in priority order.
- ✓
Allow
Why this is correct
The allow rule with higher priority (1000) matches first, so traffic is allowed.
- ✗
Depends on the default rule
Why it's wrong here
The default rule (allow or deny) applies only if no custom rule matches. Here, a custom rule matches.
