Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A Cloud CDN cache rule
Why it's wrong here
Cloud CDN is for content caching, not security policies.
- ✗
A Cloud Armor security policy with one rule that combines IP deny and rate limiting
Why it's wrong here
IP deny and rate limiting are separate rule types and cannot be combined in one rule.
- ✓
A Cloud Armor security policy with two rules: one for IP deny and one for rate limiting
Why this is correct
A single policy can contain multiple rules to achieve both requirements.
- ✗
A network firewall rule to block the IP range
Why it's wrong here
Network firewall rules operate at the network layer, not the application layer.
- ✓
An HTTPS load balancer with the security policy attached
Why this is correct
Cloud Armor policies are attached to the backend service of an HTTPS load balancer.
