Accepted Answer

Cloud Interconnect. Cloud Interconnect provides dedicated, private connections between on-prem and Google Cloud with high bandwidth and low latency. VPN uses the public internet, Cloud CDN is for content delivery, and Cloud NAT is for outbound internet access.

Answer

Cloud NAT

Answer

Cloud CDN

Answer

Cloud VPN

Question 2

A start-up wants to quickly build and deploy a web application using managed services to avoid operational overhead. They need a serverless compute platform that automatically scales and charges only for execution time. Which Google Cloud service should they use?

Accepted Answer

Cloud Run. Cloud Run is a serverless compute platform that runs containers, auto-scales, and charges per execution. Compute Engine is IaaS, Kubernetes Engine is container orchestration (not serverless), and Cloud Functions is also serverless but for event-driven functions, not full web apps with containers.

Answer

Cloud Functions

Answer

Compute Engine

Answer

Google Kubernetes Engine (GKE)

Question 3

A company is migrating its on-premises workloads to Google Cloud and wants to understand the total cost of ownership (TCO) savings. Which costs are typically LOWER in the cloud compared to on-premises?

Accepted Answer

Hardware purchase and data centre costs. Cloud eliminates hardware purchase costs (CAPEX) and reduces data centre costs (power, cooling, maintenance). Compute costs may be similar or higher depending on usage, but overall TCO is often lower due to elimination of overhead. Software licensing depends on the agreement.

Answer

Compute instance costs

Answer

Software licensing fees

Answer

Network egress charges

Question 4

A company is adopting a multi-cloud strategy to avoid vendor lock-in and use best-of-breed services. Which TWO statements accurately describe multi-cloud? (Choose 2)

Accepted Answer

It can help avoid vendor lock-in.. Multi-cloud involves using multiple public cloud providers (e.g., AWS, Azure, Google Cloud). Hybrid cloud specifically connects on-prem to cloud. Multi-cloud can increase complexity but provides flexibility.

Answer

It connects an on-premises data centre to a single public cloud.

Answer

It requires a private cloud on-premises.

Answer

It reduces management complexity.

Question 5

A company wants to use Google Cloud to innovate faster by leveraging managed services. Which TWO benefits are directly associated with using managed services? (Choose 2)

Accepted Answer

Reduced operational overhead (no patching, no server management). Managed services reduce operational overhead (no patching, no infrastructure management) and often provide built-in high availability and scaling. They do increase flexibility but may reduce control over the underlying infrastructure.

Answer

Increased control over the underlying hardware

Answer

Requires more staff to manage

Answer

Higher cost compared to self-managed solutions

Question 6

A startup wants to launch a new web application globally with minimal upfront investment and the ability to scale automatically based on traffic. Which cloud deployment model best meets these requirements?

Accepted Answer

Public cloud. Public cloud offers on-demand resources, pay-as-you-go pricing, and global reach without upfront capital expenditure.

Answer

On-premises private cloud

Answer

Hybrid cloud

Answer

Multi-cloud

Question 7

A company wants to reduce its carbon footprint by running workloads on Google Cloud. Which Google Cloud commitment directly supports this goal?

Accepted Answer

Google Cloud's 100% renewable energy match for operations. Google Cloud matches 100% of its global electricity consumption with renewable energy and aims to run on carbon-free energy 24/7 by 2030.

Answer

Choosing a region with lower CO2 equivalent per kWh

Answer

Using preemptible VMs

Answer

Using committed use discounts

Question 8

What is a key business benefit of moving from a capital expenditure (CapEx) model for IT infrastructure to an operational expenditure (OpEx) model like pay-as-you-go cloud computing?

Accepted Answer

Improved cash flow by avoiding large upfront hardware purchases. Pay-as-you-go eliminates large upfront hardware costs, converting them to variable costs based on usage, which improves cash flow and agility.

Answer

Elimination of all IT staff

Answer

Reduced need for software licenses

Answer

Guaranteed performance improvement

Question 9

An enterprise is planning to migrate its on-premises data center to Google Cloud to avoid a hardware refresh cycle. The migration must minimize application changes. Which migration strategy should they prioritize?

Accepted Answer

Lift and shift (rehost). Lift and shift (rehost) moves applications as-is to cloud VMs, minimizing changes while avoiding hardware refresh costs.

Answer

Re-architecting applications to use microservices

Answer

Replacing applications with SaaS

Answer

Refactoring to use managed services like Cloud SQL

Question 10

A media company needs to deliver video content to users worldwide with low latency. They want to cache content at edge locations. Which Google Cloud service should they use?

Accepted Answer

Cloud CDN. Cloud CDN uses Google's global edge network to cache content close to users, reducing latency for media delivery.

Answer

Cloud Storage

Answer

Cloud Load Balancing

Answer

Cloud Interconnect

Question 11

Which cloud benefit allows a company to automatically add or remove computing resources based on demand, avoiding both over-provisioning and under-provisioning?

Accepted Answer

Elasticity. Elasticity (a form of scalability) enables automatic adjustment of resources to match demand, optimizing cost and performance.

Answer

High availability

Answer

Pay-as-you-go

Answer

Global reach

Question 12

A company is evaluating Total Cost of Ownership (TCO) for migrating from on-premises to Google Cloud. Which cost is typically reduced or eliminated in the cloud?

Accepted Answer

Data center facility and hardware maintenance costs. On-premises costs like data center facility, power, cooling, and hardware maintenance are eliminated in the cloud, as the provider manages the infrastructure.

Answer

Software subscription fees

Answer

Cloud storage costs

Answer

Internet bandwidth costs

Question 13
