Answer: Cloud IoT Core with public/private key pairs
The correct answer is B, Cloud IoT Core with public/private key pairs. Cloud IoT Core is specifically designed for managing IoT device connections at scale, providing built-in security with public/private key pairs and supporting the ingestion of data from multiple devices securely. This aligns with the technical requirements of reducing latency, creating a backup strategy, and enhancing data security. Other options like Google Kubernetes Engine with an SSL Ingress or Compute Engine with SSH keys do not provide the same level of IoT-focused capabilities and security features needed for this scenario.

TerramEarth manufactures heavy equipment for mining and agriculture, with 20 million vehicles in operation. Approximately 200,000 of these vehicles are connected to a cellular network, generating vast amounts of data. You are tasked with designing a new architecture for ingesting this data in real-time. Considering the technical requirements such as decreasing latency, creating a backup strategy, and enhancing data security, which components should you use to ingest the data?
A
Google Kubernetes Engine with an SSL Ingress
B
Cloud IoT Core with public/private key pairs
C
Compute Engine with project-wide SSH keys
D
Compute Engine with specific SSH keys
