Google PCA Practice Question: A media streaming company wants to serve video…
A media streaming company wants to serve video content globally with low latency. They plan to cache static objects (thumbnails, manifest files) at edge locations, while dynamic API requests are handled by a backend in a single region. Which combination should they use?
⚠ Common exam trap
The trap is confusing Cloud CDN with security or internal load balancing services, or assuming that an internal load balancer can be used for external content delivery — Cloud CDN requires an external HTTP(S) load balancer.

Correct answer & explanation
✓
Cloud CDN with an external HTTP(S) load balancer
Cloud CDN integrates with an external HTTP(S) load balancer to cache static content at Google edge locations while forwarding dynamic API requests to the backend in a single region. The external HTTP(S) load balancer provides a global anycast IP, terminates client connections at the edge, and routes requests to the backend based on URL maps. This combination is the standard Google Cloud architecture for global content delivery with low latency for static assets and centralized dynamic processing.
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 CDN with an external HTTP(S) load balancer
Why this is correct
Cloud CDN caches static objects at Google edge locations, while an external HTTP(S) load balancer fronts the single-region backend and routes dynamic API requests. Together they satisfy both the global caching and single-region dynamic handling constraints.
- ✗
Cloud CDN with an internal TCP/UDP load balancer
Why it's wrong here
An internal TCP/UDP load balancer distributes traffic only among backends inside a VPC, so it cannot serve global external users or provide edge caching. Cloud CDN is correct for caching, but pairing it with an internal load balancer fails the requirement to reach a publicly accessible backend.
- ✗
Cloud Armor with a TCP/SSL proxy load balancer
Why it's wrong here
Cloud Armor provides WAF and DDoS filtering at the load balancer; it does not cache objects at edge locations. It tempts as an edge security layer, but caching static content requires Cloud CDN, with the TCP/SSL proxy load balancer fronting the single-region backend.
- ✗
VPC peering with Cloud NAT
Why it's wrong here
VPC peering links two VPC networks privately, and Cloud NAT provides outbound internet for instances without external IPs; neither caches content at edge locations nor terminates global client requests. They suit private cross-network connectivity or egress-only workloads, not the edge caching and single-region dynamic backend this scenario requires.

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.
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.
