Cloud Digital Leader Google Cloud Products and Services Practice Question
What is the primary purpose of Google Cloud Armor?
⚠ Common exam trap
GCDL often tests the confusion between Cloud Armor (security/DDoS) and Cloud CDN (performance) or Cloud NAT (outbound connectivity), tricking candidates who associate 'edge' services with content delivery rather than protection.
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
✓
To protect applications from DDoS attacks and application-level threats
Google Cloud Armor is a security service that provides DDoS protection and WAF capabilities for applications behind Google Cloud load balancers. It filters malicious traffic at the edge, protecting against Layer 3/4 DDoS and Layer 7 application attacks like SQL injection and XSS. It is the primary tool for edge security in GCP.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
To accelerate content delivery globally
Why it's wrong here
Cloud Armor is not a CDN; it does not cache or distribute content at edge locations. Instead, Cloud Armor operates at the edge of Google's network to filter traffic before it reaches your load-balanced backends, enforcing security policies. Content acceleration is handled by Cloud CDN, which caches static and dynamic content closer to users.
- ✓
To protect applications from DDoS attacks and application-level threats
Why this is correct
Cloud Armor provides built-in protections against volumetric DDoS attacks and a web application firewall (WAF) to block OWASP Top 10 threats like SQL injection and cross-site scripting. It uses preconfigured rules and adaptive protection to filter malicious traffic at the edge, only forwarding legitimate requests to backend services. This makes it the primary DDoS and application-layer security service for applications fronted by Cloud Load Balancing.
- ✗
To provide outbound internet connectivity to private instances
Why it's wrong here
Cloud Armor is an inbound security service, not a connectivity mechanism. Outbound internet access from private VMs is enabled by Cloud NAT, which translates private IP addresses to external IPs. Cloud Armor inspects incoming HTTP(S) and TCP/UDP traffic to your load balancers, whereas Cloud NAT handles source network address translation for egress traffic.
- ✗
To manage virtual private cloud networking
Why it's wrong here
Cloud Armor operates at the application/network layer as a security policy engine for load-balanced traffic, not as a networking construct. VPC networking, including subnets, routes, and firewall rules, is managed by Cloud VPC. Cloud Armor complements VPC firewall rules but does not manage the VPC itself; it protects specific backend services from attacks.
