Quiz IBM-C1000-142

Option D is correct. Identity and access management, or IAM is used to control access to resources.

Option B is correct. Serverless computing is a cloud computing execution model that provisions computing resources on demand and offloads all responsibility for common infrastructure management tasks. They are auto- scalable so it can handle extremely active traffic periods. Serverless computing does-not means there are no physical servers utilized, of course there are servers, but we don't have to manage them, in background cloud provider manage (provisioning, scheduling, scaling, patching and more) for us, this gives developers more time to develop and optimize their front-end application code and business logic. And with serverless, customers never pay for idle capacity. They pay only for the resources required to run their applications, and only when those applications are running. Serverless is a polyglot environment, enabling developers to code in any language or framework - Java, Python, node.js - with which they're comfortable. Because serverless scales up and down on demand in response to workload, it offers significant cost savings for spiky workloads. But it does not offer the same savings for workloads characterized by predictable, steady or long-running processes; in these cases, a traditional server environment might be simpler and more cost-effective. Serverless Implementations differ across service providers, and capabilities vary, including supported runtimes, authentication, scaling and monitoring. Serverless architectures are well-suited for event-driven, IOT and stream-processing workloads most notably open-source Apache Kafka event streaming platform. Benefits: - Pay only for the time for our code will run. - Developer don't have to take care of servers or infrastructure, it maintains by cloud provider, so they can focus more on development and business logic. - API Management & Integrated event sources. - Serverless scales up and down on demand in response to workload [Exam Tips]: You can expect, few

Option D is correct. Oracle Cloud Server is a server (compute shape), It's not a server-less offering of Oracle Cloud Infrastructure. In- Correct Answer: AWS Lambda, Google Cloud Functions, Microsoft Azure Functions are automation services of AWS, GCP and Microsoft. Server-less computing is a cloud computing execution model that provisions computing resources on demand and offloads all responsibility for common infrastructure management tasks. They are auto scalable so Its can handle extremely active traffic periods.

Option C is correct. Object Storage enable you to store and access unstructured data anywhere in the world with a self- service portal backed by RESTful APIs. Object Storage supports exponential data growth and cloud-native workloads with built-in high- speed file transfer capabilities, cross-region offerings and integrated services. Cloud object storage makes it possible to store practically limitless amounts of data, simply and cost effectively. Example use cases of cloud object storage include: - Backup and recovery - Data archiving - Cloud-native app data - AI and analytics

Option B is correct. Kubernetes is an open-source container orchestration project that simplifies everything associated with deploying and managing containers. Kubernetes, also known as K8s, is an open-source system for automating deployment, scaling, and management of containerized applications. Kubernetes is open source giving you the freedom to take advantage of on-premises, hybrid, or public cloud infrastructure, letting you effortlessly move workloads to where it matters to you. Kubernetes Features: - Automated rollouts and rollbacks - Storage orchestration - Self-healing - Secret and configuration management

Option B is correct. DevOps does not continuously integrates and automates security throughout the DevOps lifecycle, Its DevSecOps which continuously integrates and automates security throughout the DevOps lifecycle. Remaining three other options are valid for DevOps Let's understand DevOps first, DevOps is a practice of bringing development and operations teams together. With DevOps, a developer can automate the build process, code testing and deployment. DevOps used to deliver code faster to production (Continuous delivery) and iterate continuously based on market feedback. With a DevOps strategy you can do the following: - Accelerate the delivery of reliable software. - Balance speed, cost, quality, and risk with increased capacity to innovate. - Reduce time to customer feedback with improved customer experience. Common use cases for devops include cloud native and mobile applications, application integration, and modernization and multicloud management. [Exam Tips]: Remember, DevOps is used to deliver code faster to production, DevOps bring development and operation team together to deploy code to production faster.

Option A,B,C are correct. IBM Cloud® Databases and IBM Cloud® Database-as-a-Services (DBaaS) are fully managed by IBM, unless customers specifically request to manage some aspects themselves. IBM Cloud® Databases and DBaaS offers your organization significant financial, operational, and strategic benefits like below: - Your organization pays a predictable periodic charge based on the resources you consume—there’s no need to purchase additional capacity to have on hand for hypothetical future needs. - You can quickly and easily scale-up and down as per your need. - They are highly available, secure with IBM enterprise security, compatible with open-source databases, scalable, and economical including features like default encryption of data at rest and in- transit and integrated identity and access management controls. Some also meet specific regulatory compliance standards. IBM's catalog of database services includes: 1. IBM Cloudant, IBM Cloud®Databases for etcd 2. IBM Cloud® Databases for MongoDB 3. IBM Cloud® Databases for PostgreSQL 4. IBM Cloud® Databases for Redis Elasticsearch

Option A is correct. Content Delivery Network is a distributed server network that delivers temporarily stored, or cached, copies of website content to users based on the users’ geographical location to enables faster web performance. Exam tips: Remember CDN Improving website load times, by distributing content from nearby CDN server.

Option A,B,C are correct. Hybrid multicloud is hybrid cloud that combines public cloud services and private cloud services from more than one cloud service provider. As It's a combination of public cloud + private cloud so users have a choice to move workloads between public and private cloud. For example: User can keep highly sensitive data on private cloud server behind the firewall & and can use public cloud capabilities also for less-sensitive workloads and data.
