Mastering Virtualization 6.0 Questions and Answers Rated A+ 2023 Define ESXI enterprise-class, type-1 hypervisor developed by VMware for deploying and serving virtual computers. Describe Features in VSPHERE 6 A suite of products that include ESXi, vCenter, VUM, Orchestrator. Also includes features that include Virtual SMP, vMotion, DRS, Storage and Network I/O Control, Policy-Based Storage, High Availability and Fault Tolerance Explain the concept of VMOTION Technology that enables the live migration of running virtual machines from one physical server to another with zero downtime, continuous service availability, and complete transaction integrity. It is transparent to users. Identify ESXI installation options Interactive - Physical CD or mount ISO, limited configuration options PXE Network boot - Kickstart (similar to Linux) Auto Deploy - required VCenter host profiles, persistent or non-persistent, vSphere Auto Deploy can be configured with one of three different modes: Stateless, Stateless Caching, Stateful Install. Understand VSPHERE Autodeploy along with Stateful Installs Auto Deploy - required VCenter host profiles, persistent or non-persistent Stateful Install, is similar to Stateless Caching except the server's boot order is reversed: local disk first and network second. Unless the server is specifically told to network boot again, the Auto Deploy service is no longer needed. This mode is effectively just a mechanism for network installation. Understand ESXI considerations for choosing which model server Dual Core 64bit x86 CPU, 8GB RAM, 1GB NIC, SCSI, SATA, USB Disk Identify core services of VCenter ESX/ESXi host management, Resource management, Template management, VM deployment, VM management, Scheduled tasks, Statistics and logging, Alarms and event management Identify Advantages of running VCenter on a VM •Rather than dedicating a physical server to the vCenter Server application, you can install vCenter Server in a virtual machine registered to an ESXi/ESX host in the environment. •You can provide high availability for the vCenter Server system by using VMware HA. •You can migrate the virtual machine containing the vCenter Server system from one host to another, enabling maintenance and other activities. •Provides the ability to use snapshots for virtual machine-level backup utilities (such as VMware Data Recovery) and for restore points before installing update packages. Understand when to run Platform Service Controller(PSC) the Platform Services Controller (PSC). Used to run common components for VMware products in a central or in distributed location(s). The PSC offers multiple services; let's step through them so you can understand why the PSC is vital to your vSphere environment: Single Sign-On Licensing Certificate Authority Certificate Store Service Registry Understand what Vsphere Update manager(VUM) integrates with VUM integrates tightly with vSphere's inherent cluster features. It can use the Distributed Resource Scheduler (DRS) for nondisruptive updating of ESX/ESXi hosts by moving its VMs between hosts in the cluster and avoiding downtime. It can coordinate with the cluster's Distributed Power Management (DPM), High Availability (HA), and Fault Tolerance (FT) settings to ensure that they don't prevent VUM from updating at any stage. Introduced in vSphere 5, the cluster can even calculate if it can remediate multiple hosts at once while still appeasing its cluster constraints, thus speeding up the overall patching process. Understand VUM baselines Baselines are further subdivided into patch baselines, upgrade baselines, and host extension baselines. Patch baselines define lists of patches to be applied to an ESX/ESXi host; upgrade baselines define how to upgrade an ESX/ESXi host, the VM's hardware, VMware Tools, or a virtual appliance. There's also another type of baseline for hosts, known as host extension baselines; these are used to manage the extensions installed onto your ESX/ESXi hosts. VMware provides a few baselines with VUM when it's installed. The following baselines are present upon installation: Two dynamic host patch baselines named Critical Host Patches and Non- Critical Host Patches A dynamic baseline for upgrading VMware Tools to match the host A dynamic baseline for upgrading VM hardware to match the host A dynamic VA upgrade baseline named VA Upgrade To Latest Understand how vSwitches connect and Function A software-based switch that resides in the VMkernel and provides traffic management for VMs. Users must manage vSphere Standard Switches independently on each ESXi host. In this book, the term vSwitch refers to both a vSphere Standard Switch as well as a virtual switch in general. Requires ports or port groups and uplinks for any communications external to the host. Without uplinks, a virtual switch can't communicate with the upstream network; without ports or port groups, a vSwitch can't provide connectivity for the VMkernel or the VMs. Virtual switches provide the connectivity to provide communication as follows: Between VMs within an ESXi host Between VMs on different ESXi hosts Between VMs and other virtual or physical network identities connected via the physical network For VMkernel access to networks for vMotion, iSCSI, NFS, Virtual SAN, provisioning, vSphere Replication, or fault tolerance logging (and management on ESXi) Understand how Port Groups connect and Function Port groups differentiate between the types of traffic passing through a vSwitch, and they also operate as a boundary for communication and/or security policy configuration. A logical object on a vSwitch that provides specialized services for the VMkernel or VMs. A virtual switch can contain a VMkernel port or a VM port group. On a vSphere Distributed Switch, these are called distributed port groups.
