Question:- Name different components used in VMware infrastructure.
Answer:- Different components used in VMware infrastructure includes • It consists of the lowest layer which acts as an ESX server host • It also uses the virtual center server which keeps tracks of all the VM associated images and manages it from one point • VMWare infrastructure client, it enables the client to communicate with user’s applications that are running on VMware • Web-browser is used to access the virtual machines • The license server is used to prepare a server which provides licensing to the applications • Database servers are availed to maintain a database
Question:- Explain vCloud Suite
Answer:- vCloud Suite combines with multiple VMware components to give a complete set of cloud infrastructure capabilities in a single package, including virtualization, software-defined datacenter services, disaster recovery, application management, etc.
Question:- What are the storage and availability in vCloud Suite?
Answer:- The storage and availability in vCloud Computing Suite includes Storage DRS:It place and load balance virtual machines based on storage capacity and I/O latency Storage vMotion:It employs proactive, non-disruptive storage migration to reduce virtual machine storage I/O bottlenecks and free up valuable storage capacity Application HA:It gains high availability that is bound to specific applications Data Protection: Based on EMC avamar, it deploys a back-up and recovery tool
Question:- What is Host Isolation in VMware HA (High Availability)?
Answer:- In VMware HA, it has a mechanism to detect a host isolated from the rest of the hosts in the cluster. In simple words, it uses a heartbeat to communicate another host in the cluster. When the ESX host loses its ability to connect with other hosts in a cluster through heart-beat, then ESX host will be considered as a Host Isolation.
Question:- What is the difference between VMware HA and Vmware FT?
Answer:- VMware FT is enabled per VM basis while VMware is enabled per cluster In the case of ESX host failure, virtual machines are the failed host and are re-started and powered-on the other active hosts in HA cluster. But FT-enabled virtual machines; there is no downtime. In the case of a host failure, the secondary VM will be activated, and it becomes primary and continue to run from the exact point where the primary VM is failed or left off.

Answer:- In the latest version of vSphere 5.5, it includes • ESXi Hypervisor enhancement • Virtual Machine Enhancement • VMware vCenter Server Enhancement • vSphere storage Enhancement • vSphere Networking Enhancements
Question:- What are the new features included in ESXi Hypervisor enhancement?
Answer:- In ESXi Hypervisor enhancement includes • Hot-pluggable PCIe SSD Devices:It supports SSDs (Solid State Disks) devices, and with a new enhancement, SSD device can be removed or added while a vSphere host is running. • Support for Reliable Memory Technology: vSphere ESXi hypervisor can take advantage of new hardware; vendor enabled Reliable Memory Technology, through which a region of memory is reported from the hardware to vSphere ESXi hypervisor. It is used to enhance the placement of VMKernel and other components like initial thread and hosted. It helps to protect against memory error • Enhancements to CPU C-states: A power process (C-state) is used to provide additional power savings
Question:- What is Fault Tolerant Logging?
Answer:- The communication between two ESXI host is known as Fault logging when FT is configured between them.
Question:- Explain vSS
Answer:- vSS stands for Virtual Standard Switch is responsible for communication of VMs hosted on a single physical host. It automatically detects a VM which wants to communicate with other VM on the same physical server.
Question:- Explain some features of VMware tool
Answer:- • It offers a simple wizard for setting configuration • Web browser interface • Easy maintenance of virtual machines
Question:- Define the term ’VMKenel’.
Answer:- VMWare Kernel is a proprietary kernel of VMware. It needs an operating system to boot and manage the kernel. A service console is being offered whenever VMWare kernel is booted.
Question:- What is the purpose of using Virtual Machine Port Group?
Answer:- Virtual Machine port group helps for Virtual machine communication.
Question:- Give three reasons for using VMware Workstation
Answer:- Three reasons for using VMware workstation are: • Enables the user to run more than one operating system on a single system • Saves the existing OS configuration in the form of virtual machines. • Allows you to work on different OS without switching between them.
Question:- What are pluggable devices which can be added while Virtual Machine is running?
Answer:- You can add HDDs and NIC while Virtual Machine is running.
