IBM Certified Advocate - Cloud v2 C1000-142 Book

IBM Cloud® for VMware Solutions Shared uses VMware Cloud Director to enable you to extend your VMs to the cloud with ultimate capacity and scalability, while paying only for what is consumed. With IBM managing the infrastructure up to the hypervisor, you don’t need to worry about providing updates and patching, and instead can focus on application innovation. Use Cases : Development and test, Temporary workload migration, Cost-effective disaster recovery. Note : RTO is the maximum amount of time the organization can afford to be without access to the data or application. In other words, how quickly the customer needs to recover the data and application. RPO is the amount of data an organization can afford to lose and effectively dictates how frequently they need to back up their data to avoid losing more.

Correct Answer : 1 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. Type 1 Hypervisors : ⦿ Can support multiple virtual machines ⦿ Also known as a “bare metal” hypervisors ⦿ Most frequently used and seen in the market, most secure, lower latency ⦿ Examples include VMware ESXi, Microsoft Hyper-V, open source Kernel-based Virtual Machine
