Question 2

When a company moves from maintaining its own data center to using Google Cloud, which operational responsibility does Google assume that the company previously managed?

Accepted Answer

Physical hardware maintenance, data center facilities, and network equipment management. When a company migrates from an on-premises data center to Google Cloud, Google assumes responsibility for the physical infrastructure, including hardware maintenance, facility management (power, cooling, security), and network equipment. This is the core of the cloud provider's shared responsibility model, where the provider manages the 'cloud' while the customer manages what is 'in' the cloud. Option B correctly identifies these operational responsibilities that shift to Google.

Answer

Writing and maintaining application code

Answer

Defining which users can access the company's applications

Answer

Backing up the company's application data

Question 3

An organization wants to modernize its on-premises applications. The IT team identifies three types of applications: legacy apps that can only move with significant refactoring, custom-built apps that can be containerized and moved as-is, and applications that can be replaced entirely by SaaS solutions. This categorization approach is called what?

Accepted Answer

Application portfolio assessment using migration strategies (the 6 Rs framework). The scenario describes categorizing applications based on their migration path: legacy apps requiring refactoring, custom apps suitable for containerization, and apps replaceable by SaaS. This directly aligns with the '6 Rs' framework (Rehost, Replatform, Refactor, Repurchase, Retire, Retain) used in application portfolio assessment for cloud migration. Option B is correct because the 6 Rs provide a structured way to evaluate and classify each application's optimal migration strategy.

Question 5

What is virtualization in the context of cloud computing, and why is it fundamental to how cloud providers deliver services?

Accepted Answer

Virtualization abstracts physical hardware into multiple isolated virtual machines, enabling many customers to share physical infrastructure efficiently and securely.. Virtualization is fundamental to cloud computing because it decouples the operating system and applications from the underlying physical hardware through a hypervisor (e.g., VMware ESXi, KVM, Hyper-V). This abstraction allows a single physical server to host multiple isolated virtual machines (VMs), each with its own guest OS, enabling cloud providers to achieve high resource utilization, multi-tenancy, and rapid provisioning. Without virtualization, providers would be limited to one OS per physical server, drastically reducing efficiency and scalability.

Answer

Virtualization is the process of converting physical servers into digital images for backup purposes.

Answer

Virtualization is a networking technique that routes internet traffic more efficiently.

Answer

Virtualization is a backup strategy where data is stored in multiple geographic locations.

Question 6

A traditional bank processes loan applications using manual paper-based workflows that take 2 weeks per application. The bank wants to use cloud technology to reduce this to under 24 hours. Which cloud-enabled capability primarily drives this transformation?

Accepted Answer

Cloud-based AI/ML services and workflow automation that process applications end-to-end without manual steps.. Cloud-based AI/ML services combined with workflow automation can process loan applications end-to-end without manual intervention, reducing processing time from 2 weeks to under 24 hours. This transformation is driven by the ability to automate document extraction, validation, and decision-making using services like Google Cloud Document AI and Workflows, which eliminate the bottleneck of manual paper-based workflows.

Question 7

A large enterprise runs a critical application on Google Cloud consisting of Compute Engine instances behind a TCP load balancer. The application experiences intermittent slow response times that last for about 10 minutes before returning to normal. This pattern has been occurring every few days at random times. The operations team has configured Cloud Monitoring alerts for CPU and memory, but no alerts have fired. They have also reviewed the load balancer logs and see no errors, but the latency spikes. The application logs show no errors during these periods. The team suspects a resource bottleneck but cannot find it. Further investigation reveals that the application makes synchronous calls to an external authentication service for each request. What is the most likely cause and corrective action?

Accepted Answer

The application is making synchronous calls to an external authentication service that occasionally has latency spikes; implement caching and asynchronous processing.. The intermittent latency spikes lasting ~10 minutes, with no errors in application or load balancer logs and no CPU/memory alerts, point to an external dependency issue. The synchronous calls to the external authentication service are the likely bottleneck: if that service experiences transient latency, every request is blocked, causing the application's response time to spike. Caching authentication tokens and using asynchronous processing (e.g., a queue or background refresh) decouples the application from the external service's variability, eliminating the cascading latency.

Answer

The TCP load balancer is experiencing connection draining issues; switch to a proxy-based load balancer.

Answer

The instance group's autoscaler is configured with a cooldown period that is too long; reduce the cooldown period.

Answer

The virtual machine instances are suffering from CPU throttling due to sustained use of burstable CPU; move to a machine type with more CPUs.

Question 8

A company wants to build an application that can understand and respond to natural language queries from customers (e.g., a customer support chatbot). Which Google Cloud capability should they use?

Accepted Answer

Dialogflow CX or Vertex AI Conversation. Dialogflow CX and Vertex AI Conversation are Google Cloud's purpose-built services for building conversational interfaces, including chatbots that understand natural language. They leverage natural language understanding (NLU) models to parse user intents and entities, enabling the application to respond appropriately to customer queries. This makes them the correct choice for a customer support chatbot.

Question 9

When data is transmitted between a user's browser and a Google Cloud-hosted web application over HTTPS, which security protection does this provide?

Accepted Answer

It encrypts data in transit between the user's browser and the server, preventing eavesdropping and tampering.. HTTPS (HTTP over TLS) encrypts the communication channel between the user's browser and the web server using Transport Layer Security (TLS). This ensures that any data transmitted, such as login credentials or API requests, is protected from eavesdropping and tampering while in transit. It does not protect data at rest or control access to cloud management interfaces.

Answer

It prevents unauthorized users from accessing the Google Cloud Console.

Answer

It encrypts data stored in the server's database.

Answer

It authenticates the user and verifies their permissions to use the application.

Question 13

A company is migrating its on-premises applications to Google Cloud. The security team requires that all data be encrypted both in transit and at rest. Which approach meets these requirements with minimal operational overhead?

Accepted Answer

Use HTTPS for all traffic and enable default encryption at rest with Google-managed keys.. HTTPS provides encryption in transit using TLS, and default encryption at rest with Google-managed keys encrypts data stored in Google Cloud services like Cloud Storage and Compute Engine disks without requiring any manual key management. This approach meets the security requirements with minimal operational overhead since Google handles key rotation and lifecycle management automatically.

Answer

Implement a third-party encryption tool for both transit and at rest.

Answer

Set up a VPN between on-premises and Google Cloud and rely on that for encryption.

Answer

Restrict physical access to Google Cloud data centers.

Question 14

Google's physical data center security includes multiple layers of protection. Which of the following is NOT a physical security measure Google uses at its data centers?

Accepted Answer

Customers can schedule tours of Google data centers to verify security practices directly.. Google does not offer public tours of its data centers. Allowing customers to schedule tours would introduce unnecessary security risks and is not part of Google's physical security model. Instead, Google provides transparency through third-party audit reports and certifications (e.g., SOC 2, ISO 27001) to verify security practices.

Answer

Biometric authentication and badge access controls at multiple security perimeters.

Answer

24/7 on-site security personnel who monitor the facility continuously.
