Your customer wants you to create a secure website with autoscaling based on the compute instance CPU load. You want to enhance performance by storing static content in Cloud Storage. Which resources

An external HTTP(S) load balancer is essential for distributing user traffic to a public website and supports autoscaling backends (like Managed Instance Groups). A managed SSL certificate ensures secure HTTPS connections, while a URL map (implied by the truncated option for routing) allows directing static content requests to a Cloud Storage bucket, fulfilling all specified requirements for performance enhancement and traffic distribution for a secure website.

An external network load balancer operates at Layer 4 (TCP/UDP) and does not support HTTP/HTTPS routing features like URL maps, SSL offloading (with managed certificates), or routing directly to Cloud Storage, nor does it inherently handle autoscaling based on HTTP-specific metrics.

An internal HTTP(S) load balancer is designed for traffic within a VPC network, not for public internet-facing websites. Identity-Aware Proxy (IAP) is for securing access to internal applications for specific users, not for public websites.

While an external HTTP(S) load balancer and a URL map are correct components for routing, this option does not explicitly mention the managed SSL certificate, which is crucial for meeting the "secure website" requirement, making option A more complete despite its truncation.
