Question 3

A retail bank wants to launch new digital banking features quickly to compete with fintech startups while maintaining strict regulatory compliance. Which cloud transformation strategy best addresses both agility and compliance?

Accepted Answer

Implement a cloud-native architecture using GKE, Cloud Build, and Cloud IAM with compliance auditing. It leverages cloud-native services like Google Kubernetes Engine (GKE) for containerized microservices, Cloud Build for CI/CD automation, and Cloud IAM for fine-grained access control, enabling rapid feature deployment while maintaining compliance through integrated audit logging and policy enforcement. This architecture decouples agility from security, allowing the bank to iterate quickly without sacrificing regulatory requirements like PCI-DSS or SOX.

Answer

Move everything to a public cloud without additional access controls to maximize speed

Answer

Use a lift-and-shift migration to cloud VMs and rely on manual change management

Answer

Stick with on-premise systems for compliance and use cloud only for non-sensitive data

Question 4

Which TWO of the following are key benefits of cloud technology that are transforming business operations?

Accepted Answer

Elasticity to automatically scale resources up and down. Cloud elasticity allows resources to automatically scale up or down based on demand, eliminating over-provisioning and underutilization. This dynamic adjustment is a key transformation driver, enabling businesses to handle variable workloads efficiently without manual intervention.

Answer

Physical security of data centers

Answer

Data locality to keep data within national borders

Answer

Ability to purchase reserved instances for predictable workloads

Question 5

Which TWO of the following cloud characteristics directly enable a business to innovate faster than using traditional IT?

Accepted Answer

Global infrastructure that allows launching in new regions quickly. A global infrastructure with multiple regions and edge locations allows businesses to deploy applications and services in new geographic areas rapidly, reducing time-to-market compared to building or leasing physical data centers. Option E is correct because self-service provisioning enables developers to spin up resources like virtual machines, databases, or containers in minutes via APIs or console, eliminating the weeks-long procurement and setup cycles of traditional IT, thus accelerating experimentation and iteration.

Answer

Vendor lock-in for long-term contracts

Answer

Capital expenditure model for budgeting

Answer

Customizable hardware configurations for optimal performance

Question 6

An engineering team uses the `--preemptible` flag when creating an instance for a batch data processing job that runs nightly and can tolerate interruptions. What business transformation benefit does using the `--preemptible` flag provide?

Accepted Answer

Lower cost for fault-tolerant workloads, enabling more experimentation. The `--preemptible` flag creates a preemptible VM instance that can be terminated by Google Cloud at any time, typically after 24 hours, but at a significantly lower cost (up to 60-80% discount). For batch data processing jobs that run nightly and can tolerate interruptions, this cost savings directly enables more experimentation and iterative development because teams can run more jobs or larger datasets for the same budget, accelerating innovation and business transformation.

Answer

Higher reliability for critical applications

Answer

Better performance due to dedicated hardware

Answer

Enhanced security through automatic patching

Question 7

A company uses the lifecycle configuration above for archival data that is rarely accessed. What business benefit does this provide?

Accepted Answer

Reduced storage costs by transitioning to cheaper tiers and deleting obsolete data. A lifecycle configuration is designed to automatically transition objects to lower-cost storage classes (such as infrequent access or archive tiers) as they age and to expire/delete objects once they are no longer needed, which directly lowers storage spend for rarely accessed archival data. This matches the stated scenario of archival data that is rarely accessed, where the main business benefit is cost optimization rather than performance or security. Option A does not fit because encryption is a security control, not a lifecycle action, and lifecycle rules do not provide encryption. Option B does not fit because lifecycle policies typically move data to slower, cheaper tiers, which can increase retrieval latency rather than speed it up. Option D does not fit because cross-region replication is a separate feature (e.g., S3 Cross-Region Replication) and is not what a lifecycle configuration accomplishes.

Answer

Improved data security through encryption

Answer

Faster data retrieval for frequently accessed files

Answer

Automatic replication to another region for disaster recovery

Question 8

A retail company is experiencing unpredictable traffic spikes. Which cloud characteristic allows them to automatically add resources during peak demand and remove them when demand drops?

Accepted Answer

Elasticity. Elasticity (option B) is correct because it is the cloud characteristic that automatically scales resources out during peak demand and scales them back in when demand drops, matching the retail company's unpredictable traffic spikes. Global reach (option A) refers to deploying resources across multiple geographic regions to serve users closer, not to automatic scaling. High availability (option C) focuses on keeping services continuously accessible and resilient, typically through redundancy, not on adding or removing capacity with demand. Pay-as-you-go (option D) is a billing model where you pay only for consumed resources, but it does not itself perform the automatic scaling.

Answer

Global reach

Answer

High availability

Answer

Pay-as-you-go

Question 9

A startup wants to minimize upfront costs and shift from capital expenditure to operational expenditure. Which cloud pricing model enables this transformation?

Accepted Answer

Pay-as-you-go. Pay-as-you-go (option A) is correct because it charges only for the resources consumed, with no upfront commitment or long-term contract, which directly converts capital expenditure into operational expenditure and minimizes upfront costs for a startup. Reserved instances (B) and committed use discounts (C) require a one- or three-year commitment in exchange for a discount, which reintroduces upfront or committed spend and reduces flexibility. Sustained use discounts (D) are automatic discounts for running resources for a large portion of the billing month, but they still assume ongoing usage rather than eliminating upfront costs, so they do not best fit the stated goal.

Answer

Reserved instances

Answer

Committed use discounts

Answer

Sustained use discounts

Question 10

A company wants to innovate quickly by leveraging machine learning without building models from scratch. Which Google Cloud service allows them to use pre-trained models via APIs?

Accepted Answer

Cloud Vision API. Cloud Vision API is correct because it provides pre-trained machine learning models via REST APIs, allowing the company to integrate image recognition capabilities (e.g., label detection, OCR, face detection) without building or training any models. This directly meets the requirement of leveraging ML without building from scratch, as the API abstracts all model training and deployment.

Answer

AutoML

Question 11

An organization wants to ensure business continuity by failing over to a secondary region in case of disaster. Which cloud characteristic enables this capability?

Accepted Answer

Global infrastructure. Global infrastructure refers to the distributed network of data centers across multiple geographic regions. By deploying resources in a secondary region, an organization can fail over to that region during a disaster, ensuring business continuity. This capability is unique to the cloud's global footprint, not to other characteristics like scalability or measured service.

Answer

Scalability

Answer

Measured service

Answer

Resource pooling

Question 12

A company with fluctuating demand wants to pay only for the resources it consumes, with no long-term commitments. Which Google Cloud feature allows them to automatically adjust capacity based on real-time demand?

Accepted Answer

Autoscaling. Autoscaling is the correct answer because it automatically adjusts the number of compute resources (e.g., VM instances) up or down based on real-time demand metrics such as CPU utilization, request count, or custom metrics. This allows the company to pay only for the resources it consumes without any long-term commitments, as instances are added or removed dynamically to match current load.

Answer

Cloud Armor

Answer

Committed use discounts

Answer

Preemptible VMs

Question 13

A business wants to reduce the time to market for new features by enabling developers to provision infrastructure without waiting for IT. Which cloud attribute supports this?

Accepted Answer

On-demand self-service. On-demand self-service (Option D) is the correct answer because it allows developers to provision infrastructure automatically without requiring human interaction from IT. This cloud attribute, defined by NIST SP 800-145, enables users to unilaterally provision computing resources as needed, directly reducing time to market by eliminating manual approval and setup delays.

Answer
