Question 6

A media company needs to stream live video to global viewers with low latency. They also want to protect against DDoS attacks. Which combination of Google Cloud networking services should they use?

Accepted Answer

Cloud CDN and Cloud Armor. Cloud CDN and Cloud Armor together provide low-latency global content delivery and DDoS protection. Cloud CDN caches content at edge locations to reduce latency for global viewers, while Cloud Armor provides WAF and DDoS protection at the edge. This combination directly addresses the requirements.

Answer

Cloud Interconnect and Cloud VPN

Answer

Cloud DNS and Cloud Armor

Answer

Question 7

A security team wants to restrict access to a Cloud Storage bucket so that only Compute Engine VMs in the same VPC network can read objects. The VMs do not have public IP addresses. Which configuration should they use?

Accepted Answer

Enable Private Google Access on the subnet and use VPC Service Controls to limit bucket access to the VPC.. Private Google Access allows VMs without external IPs to access Google APIs and services via the VPC network. Combined with VPC Service Controls and bucket IAM, this ensures only VMs in the VPC can access the bucket.

Answer

Assign external IPs to the VMs and use firewall rules.

Answer

Create a bucket with uniform bucket-level access and grant the `storage.objectViewer` role to `allUsers`.

Answer

Use a Cloud VPN to connect the VMs to the bucket.

Question 8

Which Google Cloud service is a managed platform for building, training, and deploying ML models, including support for AutoML and custom models?

Accepted Answer

Vertex AI. Vertex AI is a unified ML platform that combines AutoML and custom model training, tuning, and serving.

Answer

BigQuery ML

Answer

AI Platform (legacy)

Answer

Cloud TPU

Question 9

A company wants to migrate its on-premises PostgreSQL database to Google Cloud with minimal downtime. They also need the ability to perform point-in-time recovery. Which TWO services or features should they use? (Choose two.)

Accepted Answer

Cloud SQL for PostgreSQL. Cloud SQL for PostgreSQL supports database migration and point-in-time recovery. Database Migration Service provides for minimal-downtime migrations.

Answer

Cloud Spanner

Answer

Cloud SQL for MySQL

Answer

Cloud Dataflow

Question 10

A team is designing a CI/CD pipeline for a microservices application. They want to automatically build container images from source code, store them securely, and deploy to GKE. Which THREE services should they include? (Choose three.)

Accepted Answer

Cloud Build. Cloud Build (A) is correct because it is Google Cloud's managed CI/CD service that compiles source code and builds container images, and it integrates natively with GKE and Artifact Registry for automated pipelines. Artifact Registry (D) is correct because it securely stores and manages container images (and other artifacts) with IAM-based access control and vulnerability scanning, serving as the image repository the pipeline pushes to and GKE pulls from. GKE (E) is correct because it is the target runtime for deploying the containerized microservices, and it can pull images directly from Artifact Registry within the same project. Cloud Storage (B) is not the right choice because it is object storage for blobs, not a container image registry with the tagging and vulnerability features needed here. Cloud Run (C) is not correct because it is a serverless container platform, not the GKE deployment target specified in the scenario.

Answer

Cloud Storage

Answer

Cloud Run

Question 11

A startup wants to deploy a containerized web application that can scale to zero when not in use and automatically scale based on request traffic. They have limited DevOps experience and want minimal infrastructure management. Which compute service should they choose?

Accepted Answer

Cloud Run. Cloud Run is a serverless container platform that scales to zero, automatically scales based on requests, and requires no cluster management, making it ideal for this scenario.

Answer

App Engine Standard

Answer

Google Kubernetes Engine

Answer
