IBM Cloud Certification Flashcards

Which of the following must have a monitor agent deployed after establishing an instance of IBM Cloud Monitoring?

Answer: Each host

IBM Cloud Monitoring, powered by Sysdig, requires a monitoring agent to be deployed on each host (virtual machine, bare metal server, or container host) that you wish to monitor. This agent collects metrics, logs, and traces from the host and its running applications, sending them to the IBM Cloud Monitoring service for analysis and visualization. Without the agent, the service cannot gather data from the specific host.

What does IBM Cloud by default track in Activity Tracker in terms of encryption?

Answer: Events around the lifecycle of keys

IBM Cloud Activity Tracker, which records user-initiated activities and the activity of IBM Cloud services, tracks events related to the lifecycle of encryption keys. This includes actions such as creating, importing, deleting, and rotating keys within services like Key Protect or Hyper Protect Crypto Services. This auditing capability is crucial for security and compliance, providing a record of how encryption keys are managed.

Which architecture best describes an application that is made up of numerous smaller, loosely linked components that may be deployed independently?

Answer: Microservices

Microservices architecture is a design approach where an application is built as a collection of small, independent services, each running in its own process and communicating through lightweight mechanisms. These services are loosely coupled, highly maintainable, and independently deployable, allowing for greater agility, scalability, and resilience compared to monolithic applications.

What services are provided by Direct Link?

Answer: Connectivity from external sources into a private cloud network

IBM Cloud Direct Link provides dedicated, private network connections between your on-premises infrastructure and your IBM Cloud environment. This service bypasses the public internet, offering higher bandwidth, lower latency, and enhanced security for data transfer. It is specifically designed to extend your private network into the IBM Cloud, enabling seamless hybrid cloud deployments.

What type of service can be utilized to create complex machine learning models using notebooks and code-free tools to integrate AI into your company?

Answer: Watson Studio

IBM Watson Studio is an integrated platform designed for data scientists, developers, and analysts to build, run, and manage AI models. It provides a suite of tools, including Jupyter notebooks for coding, visual drag-and-drop interfaces for code-free model building, and various data science libraries, enabling users to create and deploy complex machine learning solutions.

When new contributions are merged into the main branch, automation testing that ensures the application is not broken and stops major drift, competing changes, and merge conflicts is known as?

Answer: Continuous Integration

Continuous Integration (CI) is a DevOps practice where developers frequently merge their code changes into a central repository. Automated builds and tests are then run to detect integration issues early, ensuring the application remains functional and preventing major drift or conflicts. This process directly addresses the need for automation testing to prevent breakage and manage competing changes.

What IBM Cloud role helps clients develop action plans to aid in the resolution of crucial business issues?

Answer: IBM Cloud Sales Engineer

An IBM Cloud Sales Engineer acts as a technical advisor, working closely with clients to understand their business challenges and technical requirements. They leverage their expertise in IBM Cloud offerings to design and propose solutions, developing action plans that address crucial business issues and align with client goals. Their role is to bridge the gap between client needs and IBM's technical capabilities.

An open-source container orchestration technology called Kubernetes makes it easier to install and manage _____ ? (Complete the blank)

Answer: Containers

Kubernetes is an open-source platform specifically designed for automating the deployment, scaling, and management of containerized applications. It provides a robust framework for orchestrating workloads across clusters of machines, making it the de facto standard for managing containers in production environments. Its core purpose is to simplify the operation of container-based applications.

What are the three levels of resiliency for the IBM Cloud Object Service?

Answer: Cross region, regional, and single data center

IBM Cloud Object Storage offers different resiliency levels to meet varying availability and durability requirements. These include Cross Region for maximum geographic distribution and disaster recovery, Regional for high availability within a broader geographic area, and Single Data Center for localized redundancy. These options allow users to choose the appropriate level of data protection based on their needs.

Which of the following shares responsibility for managing the lifetime of operations and safeguarding products on IBM Cloud?

Answer: IBM and the client

In a shared responsibility model, common in cloud computing, both the cloud provider (IBM) and the client share responsibility for security and operations. IBM is responsible for the security *of* the cloud infrastructure, while the client is responsible for security *in* the cloud, including their data, applications, and configurations. This partnership ensures comprehensive management and safeguarding of products.

On IBM cloud internet services, javaScript has been created by a developer and delivered to edge functionalities. What would cause the code to run?

Answer: Trigger event

Serverless functions, like those deployed to edge functionalities on IBM Cloud Internet Services, are executed in response to specific events. These 'trigger events' can be HTTP requests, database changes, file uploads, or scheduled timers, causing the JavaScript code to run only when needed. This event-driven architecture is fundamental to serverless computing.

Which IBM Cloud service offers bare metal servers, virtual servers, and storage using SAN-like iSCSI?

Answer: IBM Block Storage Service

IBM Block Storage provides persistent, high-performance storage that can be attached to virtual servers and bare metal servers. It offers block-level access, similar to a traditional SAN, making it suitable for databases, enterprise applications, and other workloads requiring low-latency, high-throughput storage. This service directly addresses the need for SAN-like iSCSI storage.

What is automatically created when a Cloud Monitoring instance is provisioned by IBM?

Answer: Access key

When a Cloud Monitoring instance is provisioned on IBM Cloud, an Access Key is automatically generated. This key is essential for authenticating and authorizing the monitoring agent to send metrics and logs to the Cloud Monitoring service, enabling data collection from your resources. Without it, the monitoring agent cannot securely communicate with the service.

There are four principles that make up identity and access management: users, access groups, resources, and resource groups. What idea exemplifies a provided service offering from a catalog?

Answer: Resources

In IBM Cloud Identity and Access Management (IAM), 'Resources' represent the specific services, instances, or data that users or access groups need to interact with. A provided service offering from a catalog, such as a database instance or a virtual server, is considered a resource to which access policies are applied. This concept defines what users can actually access and manage.

You can access your billing information in two different ways. (Choose Two)

Answer: Monthly overview

IBM Cloud billing information can typically be accessed in various granularities to help users understand their spending. A 'Monthly overview' provides a summary of total charges for a billing period, while 'Specific service' allows users to drill down and view costs associated with individual services or instances. These two methods offer both a high-level summary and detailed insights into billing.

Choose the response that fully completes the statement. For data scientists, developers, and subject matter experts, there is a set of tools and a collaborative environment called .

Answer: IBM Watson Studio

IBM Watson Studio is an integrated platform designed for data scientists, developers, and subject matter experts. It provides a collaborative environment with a comprehensive set of tools for data preparation, model building, training, and deployment across the AI lifecycle. This makes it a central hub for all aspects of data science and AI development.
