Question 4: What is the function of a GCP 'Shared VPC'?
- Peers two VPCs in different organizations
- Allows multiple service projects to use a network defined in a host project (Correct answer)
- Provides a global anycast IP for Cloud Load Balancing
- Encrypts traffic between VPCs automatically
Correct answer: Allows multiple service projects to use a network defined in a host project
Shared VPC lets an organization share a single VPC network (defined in a host project) across multiple service projects, centralizing network administration.
Question 5: Which GCP database service is best suited for globally distributed ACID transactions with horizontal scaling?
- Cloud SQL
- Firestore
- Cloud Spanner (Correct answer)
- Cloud Bigtable
Correct answer: Cloud Spanner
Cloud Spanner provides globally distributed, strongly consistent ACID transactions with horizontal scaling, unique among relational databases.
Question 6: When using Google Kubernetes Engine, what is the difference between a node pool and a cluster?
- A cluster is a single VM; a node pool is a group of clusters
- A cluster is the overall GKE environment containing one or more node pools of Compute Engine VMs (Correct answer)
- A node pool is managed by Autopilot; a cluster is managed by Standard mode only
- They are interchangeable terms in GKE documentation
Correct answer: A cluster is the overall GKE environment containing one or more node pools of Compute Engine VMs
A GKE cluster is the top-level GKE resource, and a node pool is a group of nodes within that cluster sharing the same configuration (machine type, image, etc.).
