Accepted Answer

Organization node (root)

Answer

Policies attached at the organization node apply to all folders, projects, and resources within the organization and cannot be overridden lower in the hierarchy.

Question 2

What is the primary architectural advantage of using Cloud Bigtable over Cloud Firestore for IoT time-series data at massive scale?

Accepted Answer

Bigtable provides sub-millisecond latency at petabyte scale with optimized row key design for time-series

Answer

Cloud Bigtable is a wide-column NoSQL database engineered for sub-millisecond reads/writes at petabyte scale, making it ideal for high-volume time-series IoT data.

Question 3

A cloud architect needs to connect an on-premises data center to Google Cloud with a dedicated, low-latency, high-bandwidth connection. Which solution is appropriate?

Accepted Answer

Dedicated Interconnect

Answer

Dedicated Interconnect provides a direct physical connection between on-premises infrastructure and Google's network, offering up to 200 Gbps with low latency.

Question 4

When designing a disaster recovery plan on Google Cloud, what does an RTO (Recovery Time Objective) measure?

Accepted Answer

The maximum acceptable time to restore service after a disaster

Answer

RTO is the maximum acceptable elapsed time from a disaster event to the restoration of service to an acceptable performance level.

Question 5

Which approach best enables a microservices architecture on Google Cloud to handle cascading failures through circuit-breaking and observability?

Accepted Answer

Use Anthos Service Mesh (Istio) for service-to-service traffic management, circuit breaking, and distributed tracing

Answer

Anthos Service Mesh (based on Istio) provides traffic management, circuit breaking, retries, timeouts, and distributed tracing for microservices without code changes.
