Cloud Digital Leader Practice Question: Google Cloud products, services, and solutions
A company is deploying a global web application with static content (images, CSS, JS) and dynamic API calls. They want to reduce latency for users worldwide. Which TWO services should they combine? (Choose 2)
⚠ Common exam trap
Watch out — candidates often confuse Cloud CDN with Cloud Armor or Cloud DNS, thinking security or DNS services can reduce latency, but only CDN combined with a global load balancer provides edge caching and anycast routing for static and dynamic content.
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
✓
Cloud CDN
Cloud CDN (option B) caches static content (images, CSS, JS) at Google's globally distributed edge points of presence (PoPs), reducing latency for users by serving content from a location closer to them. The External HTTP(S) Load Balancer (option C) is required to front the application and integrate with Cloud CDN, providing global anycast IP, SSL termination, and traffic distribution to backend instances. Together, they enable low-latency delivery of both static and dynamic content by combining edge caching with intelligent load balancing.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Cloud VPN
Why it's wrong here
Cloud VPN establishes an IPsec-encrypted tunnel between your VPC and on-premises networks for private, secure data transport. It does not include any caching or edge-serving capabilities, so it cannot reduce latency for global users requesting static content; it is purely a connectivity solution for private traffic.
- ✓
Cloud CDN
Why this is correct
Cloud CDN leverages Google's global edge PoPs to cache static responses (images, CSS, JS) close to end users, dramatically cutting latency and reducing origin load. It integrates with External HTTP(S) Load Balancing to honor cache-control headers and TTLs, making it the direct service for low-latency static content delivery.
- ✓
External HTTP(S) Load Balancer
Why this is correct
External HTTP(S) Load Balancer uses a global anycast IP to route requests to the nearest healthy backend and terminates TLS at the Google edge. While this improves connection setup time and provides smart traffic distribution, it does not cache content by itself—dynamic requests still traverse to the origin, so it alone doesn't solve latency for repeat static assets.
- ✗
Cloud Armor
Why it's wrong here
Cloud Armor is a web application firewall (WAF) and DDoS protection service that inspects HTTP(S) traffic against configurable security policies (e.g., IP allowlists, OWASP rules, rate limiting). It operates at the edge but adds only security inspection, not caching or content delivery, so it never reduces the network distance content must travel.
- ✗
Cloud DNS
Why it's wrong here
Cloud DNS provides global, anycast-based domain name resolution, translating names like example.com into IP addresses. It is a control-plane lookup system only; once a browser connects to the returned IP, Cloud DNS plays no role in serving content, so it cannot cache or accelerate delivery of static assets.

Key term
Load balancer
A load balancer is a device or software that distributes incoming network traffic across multiple servers so no single server gets overwhelmed.
Key term
Cloud CDN
A Cloud CDN is a network of servers spread around the world that stores copies of your website or app content so it loads faster for users no matter where they are.
