Question 10

A company wants to use pre-trained Google AI models to add vision capabilities to their application — specifically to detect objects in images and extract text from scanned documents — without training their own models. Which Google Cloud APIs provide these capabilities?

Accepted Answer

Cloud Vision API for object detection and OCR; Cloud Document AI for structured document extraction.. Option A is correct because Cloud Vision API provides pre-trained models for object detection and OCR (Optical Character Recognition) to extract text from images, while Cloud Document AI specializes in extracting structured data (e.g., fields, tables) from scanned documents. Both services require no custom training, aligning with the company's requirement to use pre-trained Google AI models.

Answer

BigQuery ML for both use cases — it trains vision models on image data stored in BigQuery.

Answer

Vertex AI AutoML Vision — train a custom model on your own images.

Answer

Cloud Natural Language API for text extraction from images.

Question 11

A company runs many containerized microservices that need orchestration — automatic scheduling, scaling, self-healing, and rolling updates. They want a managed service so they don't maintain the control plane themselves. Which Google Cloud service is purpose-built for this?

Accepted Answer

Google Kubernetes Engine (GKE). Google Kubernetes Engine (GKE) is a managed Kubernetes service that provides automatic orchestration, scaling, self-healing, and rolling updates for containerized microservices. It fully manages the Kubernetes control plane, including the API server, etcd, and scheduler, so the customer does not have to maintain them.

Question 13

A company's web application faces DDoS attacks and SQL injection attempts from the internet. They need a service that sits in front of their load balancer to block malicious traffic before it reaches their application servers. Which Google Cloud service provides this protection?

Accepted Answer

Cloud Armor. Cloud Armor is Google Cloud's web application firewall (WAF) and DDoS mitigation service that operates at the edge of Google's network, in front of the load balancer. It can filter incoming traffic based on Layer 7 rules (e.g., SQL injection patterns, cross-site scripting) and Layer 3/4 conditions (e.g., IP reputation, rate limiting), blocking malicious requests before they reach the load balancer or application servers. This makes it the correct choice for protecting against both DDoS attacks and SQL injection attempts at the network perimeter.

Question 14

An enterprise wants employees to access internal web applications securely from any location (including remote work from home) without using a VPN. Employees should only access apps they're authorized for, based on their identity and device context. Which Google Cloud service enables this zero-trust access model?

Accepted Answer

Cloud Identity-Aware Proxy (IAP). Cloud Identity-Aware Proxy (IAP) is the correct service because it enforces zero-trust access by verifying a user's identity and device context before granting access to internal web applications, without requiring a VPN. It uses Google's BeyondCorp model to authenticate and authorize each request based on identity and context, allowing secure access from any location.
