A financial organization needs to set up a secure, low-latency API gateway that can handle high levels of traffic and integrate with existing microservices. Which GCP services should you recommend for meeting these requirements?

*Explanation:* To set up a secure, low-latency API gateway that can handle high traffic and integrate with existing microservices, you should recommend **Kubernetes Engine** and the **Apigee API Platform**. Kubernetes Engine provides a scalable and reliable platform for running microservices, and Apigee offers comprehensive API management, security, and traffic handling capabilities. Cloud Endpoints and Cloud Armor are suitable for API management but lack the robust security features of Cloud Armor. Cloud Run and Cloud CDN can handle high traffic but are not specialized for API management. Cloud Functions and Cloud NAT may not fulfill all the requirements, and App Engine and Load Balancer are not specifically designed for secure, low-latency API gateway needs.
