   An organization needs to run frequent updates for their business app. Why should the organization use Google Kubernetes Engine (GKE)?

   • ACustomer expectations can be adjusted without using marketing tools
   • BSeamless changes can be made without causing any application downtime.
   • CGKE handles version control seamlessly and out of the box
   • DGKE is well suited for all monolithic applications

   Show answer

   Answer: B

   Explanation

   he answer to the question is B. Seamless changes can be made without causing any application downtime. GKE provides a number of features that make it well-suited for organizations that need to run frequent updates for their business apps. These features include: Automatic upgrades: GKE can be configured to automatically upgrade clusters to the latest Kubernetes version. This means that you can be confident that your apps are always running on the latest and greatest software. Rolling updates: GKE supports rolling updates, which allow you to update your clusters without causing any application downtime. This is done by updating one node at a time, and then rolling the update out to the rest of the cluster once the first node has been successfully updated.

3. Question 263 · 288 in bank

   An e-commerce organization is reviewing their cloud data storage. What type of raw data can they store in a relational database without any processing?

   • AProduct inventory
   • BProduct photographs
   • CInstructional videos
   • DCustomer chat history

   Show answer

   Answer: A

   Explanation

   Product inventory data, such as product names, descriptions, pricing, and inventory levels, can be stored in a relational database without any processing. This type of structured data is commonly stored in a database to track and manage the organization's product inventory. Product photographs are typically large files in image format (JPEG, PNG, etc.) and are considered unstructured data. Storing these files directly in a relational database is not efficient or recommended. Similar to product photographs, instructional videos are typically large files in video format (MP4, AVI, etc.) and are considered unstructured data. Storing videos directly in a relational database is not efficient. Customer chat history often consists of unstructured text data, including messages, timestamps, and metadata. Relational databases are designed for structured data, and storing unstructured text data directly in a database is not optimal.

4. Question 264 · 288 in bank

   A hotel wants to modernize their legacy systems so that customers can make reservations through a mobile app. What's the benefit of using an application programming interface (API) to do this?

   • AThey do not have to develop the end-user application
   • BThey can deprecate their legacy systems
   • CThey can transform their systems to be cloud-native
   • DThey do not have to rewrite the legacy system

   Show answer

   Answer: D

   Explanation

   Organizations can package existing legacy services in a way that makes them more consumable by the business, by either wrapping services with RESTful APIs, or exposing access to constituent web service operations through APIs.

5. Question 265 · 288 in bank

   An organization wants to digitize and share large volumes of historical text and images. Why is a public cloud a better option than an on-premises solution?

   • AIn-house hardware management
   • BProvides physical encryption key
   • CCost-effective at scale
   • DOptimizes capital expenditure

   Show answer

   Answer: C

   Explanation

   Public cloud services operate on a pay-as-you-go model, meaning you only pay for the resources you use. This eliminates the need for upfront infrastructure investments, hardware maintenance, and ongoing operational costs associated with on-premises solutions. Additionally, you can take advantage of the cloud provider's economies of scale, reducing the overall cost of storage and processing.

6. Question 266 · 288 in bank

   You are a program manager within a Software as a Service (SaaS) company that offers rendering software for animation studios. Your team needs the ability to allow scenes to be scheduled at will and to be interrupted at any time to restart later. Any individual scene rendering takes less than 12 hours to complete, and there is no service-level agreement (SLA) for the completion time for all scenes. Results will be stored in a global Cloud Storage bucket. The compute resources are not bound to any single geographical location. This software needs to run on Google Cloud in a cost-optimized way. What should you do?

   • ADeploy the application on Compute Engine using preemptible instances
   • BDevelop the application so it can run in an unmanaged instance group
   • CCreate a reservation for the minimum number of Compute Engine instances you will use
   • DStart more instances with fewer virtual centralized processing units (vCPUs) instead of fewer instances with more vCPUs

   Show answer

   Answer: A

   Explanation

   Preemptible VMs are cost-effective instances that can be used for short-lived and non-critical workloads. Since the rendering of individual scenes takes less than 12 hours and can be interrupted and restarted, you can leverage preemptible VMs to perform the rendering tasks. Preemptible VMs are available at a significantly lower cost compared to regular instances but can be preempted by GCP with a 30-second notice. By designing your rendering workflow to handle interruptions gracefully, such as checkpointing and resuming, you can take advantage of the cost savings provided by preemptible VMs.

7. Question 267 · 288 in bank

   An organization wants to develop an application that can be personalized to user preferences throughout the year. Why should they build a cloud-native application instead of modernizing their existing on-premises application?

   • ADevelopers can rely on the cloud provider for all source code
   • BDevelopers can launch new features in an agile way
   • CIT managers can migrate existing application architecture without needing updates
   • DIT managers can accelerate capital expenditure planning

   Show answer

   Answer: B

   Explanation

   Agile development is not only used in the cloud, so do not fully agree with B. However, it can be done quickly but only if the functionality is present in the cloud.

8. Question 268 · 288 in bank

   Which technology allows organizations to run multiple computer operating systems on a single piece of physical hardware?

   • AHypervisor
   • BContainers
   • CServerless computing
   • DOpen source

   Show answer

   Answer: A

   Explanation

   A hypervisor is a specific type of software or firmware that enables virtualization by creating and managing virtual machines (VMs). It is the underlying technology that allows multiple operating systems to run on a single physical server. The hypervisor sits between the hardware and the virtual machines, providing an abstraction layer that allows the operating systems running in the virtual machines to interact with the underlying hardware resources. It manages the allocation and sharing of physical resources such as CPU, memory, storage, and networking among the virtual machines.

9. Question 269 · 288 in bank

   An organization is making a strategic change to customer support in response to feedback. They plan to extend their helpline availability hours. Why is the organization making this change?

   • AUsers expect professional expertise
   • BUsers require personalization
   • CUsers expect always-on services
   • DUsers require regional access

   Show answer

   Answer: C

   Explanation

   Extending helpline availability hours ensures that the organization's customer support services are available for a longer duration, providing users with access to assistance and support whenever they need it. By offering an "always-on" service, the organization can meet the expectations of users who require support outside of regular business hours.
