Cloud Digital Leader Google Cloud Products and Services Practice Test 5 — 15 Questions

Question 1

A startup wants to deploy a containerized web application that can scale to zero during periods of no traffic, and they want to minimize operational overhead. Which Google Cloud compute service is the BEST fit?

Accepted Answer

Cloud Run. Cloud Run is a serverless container platform that automatically scales your containers up and down, including scaling to zero when there is no traffic. It abstracts away infrastructure management, making it ideal for this use case.

Answer

App Engine Flexible Environment

Answer

Google Kubernetes Engine (GKE)

Answer

Compute Engine with managed instance groups

Question 2

A company runs a batch processing workload every night that can tolerate interruptions. The workload runs on Compute Engine VMs and takes 2 hours to complete. They want to reduce costs. Which VM pricing model should they use?

Accepted Answer

Preemptible VMs. Preemptible VMs offer significant cost savings (up to 80% discount) but can be terminated at any time. Since the workload is batch and can tolerate interruptions, this is the most cost-effective choice.

Answer

Committed use discounts

Answer

Sole-tenant nodes

Answer

Sustained use discounts

Question 3

An engineer needs to deploy a containerized application on Google Kubernetes Engine (GKE) and ensure that each pod gets a static IP address that persists across rescheduling. Which networking approach should they use?

Accepted Answer

Use a VPC-native cluster and assign a static internal IP using the `networking.gke.io/static-ip` annotation.. GKE supports static IP addresses for pods using VPC-native clusters and alias IP ranges. By reserving a static internal IP address and assigning it to the pod via a Kubernetes annotation, the IP persists even if the pod is rescheduled.

Answer

Use a load balancer service of type LoadBalancer.

Answer

Use a DaemonSet to ensure one pod per node.

Answer

Use a StatefulSet with a headless service.

Question 4

A data analyst needs to run ad-hoc SQL queries on a large dataset stored in Cloud Storage. The data is in CSV format and does not require real-time results. Which Google Cloud service should they use?

Accepted Answer

BigQuery. BigQuery supports external data sources; you can create an external table pointing to CSV files in Cloud Storage and run SQL queries without loading the data. This is ideal for ad-hoc analysis on existing data.

Answer

Dataflow

Answer

Cloud SQL

Answer

Cloud Dataproc

Question 5

Which Google Cloud service is a fully managed, serverless data warehouse for analytics with built-in ML capabilities (e.g., BigQuery ML)?

Accepted Answer

BigQuery. BigQuery is a serverless data warehouse that supports standard SQL, scales automatically, and includes BigQuery ML for creating ML models using SQL.

Answer

Cloud SQL

Answer

Firestore

Answer

Cloud Spanner

Question 6

An organization needs to store archival data that must be retained for 10 years and is accessed less than once a year. Which Cloud Storage class offers the lowest storage cost?

Accepted Answer

Archive. Archive storage is the lowest-cost storage class for long-term retention, with a 365-day minimum storage duration and higher retrieval costs.

Answer

Standard

Answer

Coldline

Answer

Nearline

Question 7

A company uses Cloud SQL for MySQL and needs to migrate to a PostgreSQL-compatible database that offers improved performance for AI workloads (e.g., vector embeddings). Which Google Cloud database is MOST suitable?

Accepted Answer

AlloyDB. AlloyDB is a PostgreSQL-compatible database that is optimized for high performance and features like vector embeddings for AI, making it ideal for this migration.

Answer

Cloud SQL for PostgreSQL

Answer

Cloud Spanner

Answer

Bigtable

Question 8

A developer wants to trigger a serverless function in response to a file being uploaded to a Cloud Storage bucket. Which Google Cloud service should they use?

Accepted Answer

Cloud Functions. Cloud Functions is an event-driven serverless compute service that can be triggered by Cloud Storage events (e.g., object finalize).

Answer

Compute Engine

Answer

Cloud Run

Answer

App Engine

Question 9

Which Google Cloud service provides a managed Redis or Memcached in-memory data store for caching and low-latency data access?

Accepted Answer

Memorystore. Memorystore is the fully managed in-memory data store service for Redis and Memcached, used for caching and low-latency access.

Answer

Firestore

Answer

Bigtable

Answer

Cloud SQL

Question 10

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 caches content at edge locations for low-latency delivery, and Cloud Armor provides DDoS protection and WAF capabilities at the edge.

Answer

Cloud Interconnect and Cloud VPN

Answer

Cloud DNS and Cloud Armor

Answer

Cloud Load Balancing and Cloud NAT

Question 11

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 12

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 13

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

Question 14

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 builds container images from source; Artifact Registry stores the images; GKE is the deployment target. Cloud Deploy could also be used for continuous delivery, but the three most essential are Build, Artifact Registry, and GKE.

Answer

Cloud Storage

Answer

Cloud Run

Question 15

A company uses Cloud Functions to process events from Pub/Sub. Which TWO statements about this architecture are correct? (Choose two.)

Accepted Answer

Cloud Functions can acknowledge messages automatically upon successful execution.. Cloud Functions can be triggered by Pub/Sub messages. The functions scale automatically based on the number of messages, and they are stateless and short-lived.

Answer

Cloud Functions must be associated with a VPC to access Pub/Sub.

Answer

Cloud Functions can run for up to 60 minutes per invocation.

Answer

Cloud Functions can be used to pull messages from a Pub/Sub subscription synchronously.
