Remember below severity level 4 = Minimal 3 = Some 2 = Significant 1 = Critical

A resource is the instance of the service

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

Explanation

IBM Cloud Kubernetes Service is a certified Kubernetes provider that enables customers to create their own Kubernetes cluster of compute hosts to deploy and manage their containerized apps.

IBM Cloud Architects recommend and design cloud solutions to solve client problems

SSL (Secure Socket Layer) allows information to travel from browser to server and back again using a secured transmission tunnel to combat eavesdropping. Verification amount depends on the style of SSL certificate involved. You can manage your SSL certificates in the IBM Cloud® console. Within the IBM Cloud console, all SSL certificates ordered through IBM Cloud can be managed from the SSL Orders screen. This screen tracks all orders, including the common name, certificate type, and expiration date of the certificate but does not contain any certificate-specific details such as the certificate itself or the Private Key. From this screen, current and expired SSL certificates can be renewed under their pre-existing terms, and fulfillment emails can be requested to receive the SSL certificate details if they are lost. All requests that are made from the SSL Orders screen are routed to the appropriate certificate authority for the SSL certificate, which fulfills the requests as necessary. Because IBM Cloud does not possess the SSL certificate details, IBM Cloud is unable to provide any additional information about the certificate.

IBM Cloud® has three main types of accounts mentioned below : Lite Account : IBM Cloud® Lite Account to access to over 40 services at free of cost, There is No credit card required, and the account never expires. Pay-as-You-Go: IBM Cloud® Pay-As-You-Go account, you can access the full IBM Cloud catalog, including all Free and Lite plans. You pay only for billable services that you use, no long-term commitment required, You will get bill monthly based on your usages. Subscription accounts : IBM Cloud® Subscription accounts offer many of the same benefits as Pay-As-You-Go accounts, including access to the full IBM Cloud catalog and the ability to create multiple resource groups. In addition, Subscription accounts provide discounts for platform services and support and more consistent billing through subscriptions. Exam Tips : You can expect few questions in exam from IBM Cloud® account type. Remember : Lite account is free, no credit card required , and allow free access to 40 services. Pay-as-You-Go is billing utility model, where you have to pay bill monthly. Subscription accounts offer discount, available for enterprises, and required long term commitment

Correct Answer : Infrastructure-as-a-service would be one and only option for an organization, if they just want to access to servers and storage devices but does not want to buy them. Their own employee (Usually system admin) can install and maintain the computing platform and application software.

Correct Answer : Hypervisor is a small software layer that enables multiple operating systems to run alongside each other. Hypervisor separates the VMs logically, assigning each its own slice of underlying computing power, memory, and storage. There are 2 types of Hypervisor : Type 1 & Type 2. Hosted is another name given to a Type 2 hypervisor. Type 2 Hypervisors : Run as an application in a host operating system, rather than in place of an operating system ⦿ Create a virtual machine and install a guest operating system on it ⦿ Assign physical resources to a virtual machine and set the amount of processor cores and memory it can use ⦿ Known as “hosted” ⦿ Mostly used for end-user virtualization, less frequently used, higher latency ⦿ Some examples are Oracle VirtualBox and VMware Workstation In-Correct Answers : Virtual Machine : A virtual machine is a virtual representation of physical computer, that behaves like an actual computer. Single Tenant : Sigle tenant means, used by single organization only. Bare metal server are single-tenant physical servers that are dedicated to a single customer. Bare metal servers fulfill the demanding needs of high-performance computing (HPC) and data intense applications. Use cases : Bare metal server are suitable for CPU and I/O intensive workloads.
