vSphere
What is vMotion in VMWare vSphere, and what does it allow you to do?
A feature in VMWare vSphere that enables live migration of virtual machines from one physical server to another without any downtime, allowing for workload balancing, maintenance, and optimal resource utilization.
What is a Virtual Switch (vSwitch) in VMWare vSphere, and how does it facilitate network connectivity for virtual machines?
A software-based network switch in VMWare vSphere that enables virtual machines to connect to external networks and communicate with other virtual machines within the same host or across multiple hosts in a cluster.
What is a VMWare vSphere datastore, and how is it used to store virtual machine files?
A storage location where virtual machine files, such as virtual disks, templates, and ISO images, are stored. It can be a block-level storage device or a file-level storage system accessible to ESXi hosts. The datastore provides the necessary space for storing and accessing virtual machine files.
What is VMWare vSphere PowerCLI, and how does it enable automation and scripting?
VMWare vSphere PowerCLI is a command-line interface and scripting environment based on PowerShell. It enables administrators to automate and script various management tasks in VMWare vSphere, allowing for efficient and scalable management of virtualized environments.
VMWare ESXi is the bare-metal hypervisor used in VMWare vSphere. What does "ESXi" stand for?
Elastic Sky X Integrated
How does VMWare Distributed Resource Scheduler (DRS) help with workload balancing in a vSphere cluster?
DRS continuously monitors resource usage in a vSphere cluster and automatically balances the workload across the available hosts by migrating virtual machines based on resource utilization and priority settings.
What is a VLAN , and how is it configured in VMWare vSphere?
A logical network segment that allows the grouping of virtual machines based on their network requirements or security policies. In vSphere, VLANs are configured by assigning a VLAN ID to a virtual switch port group, which tags the network traffic with the corresponding VLAN identifier.
What is thin provisioning in VMWare vSphere, and how does it optimize storage utilization?
Thin provisioning is a storage provisioning technique in VMWare vSphere that allows virtual machines to be allocated storage space dynamically as needed, rather than allocating the full provisioned size upfront. It optimizes storage utilization by allocating space on-demand, reducing wasted space and improving overall storage efficiency.
How does VMWare vSphere Update Manager (VUM) assist with patching and updating ESXi hosts and virtual machines?
VMWare vSphere Update Manager (VUM) is a tool that helps automate the process of patching and updating ESXi hosts and virtual machines. It provides centralized management, assessment of host compliance, and facilitates the installation of patches, updates, and extensions across the vSphere infrastructure.
What is the main purpose of VMWare vCenter Server in the vSphere environment?
To manage and centralize the administration of vSphere virtualized environments.
What is High Availability (HA) in VMWare vSphere, and how does it ensure VM availability?
A feature that provides automatic detection of host failures and restarts affected virtual machines on the remaining hosts in a cluster, ensuring high availability and minimizing downtime
What is Network I/O Control (NIOC) in VMWare vSphere, and how does it help prioritize network traffic?
A feature that allows administrators to prioritize and allocate network bandwidth to different types of network traffic. It helps ensure that critical traffic, such as storage or management traffic, gets the necessary bandwidth to function properly, preventing performance degradation.
What is Storage vMotion in VMWare vSphere, and what does it allow you to do?
Storage vMotion is a feature in VMWare vSphere that enables live migration of a running virtual machine's storage from one datastore to another, without any downtime or impact to the virtual machine. It allows for flexible storage management, load balancing, and storage maintenance operations.
What is the purpose of VMWare vSphere Web Client, and how does it differ from the vSphere Client?
VMWare vSphere Web Client is a web-based graphical user interface that provides a comprehensive management interface for VMWare vSphere. It allows administrators to manage and configure virtual machines, hosts, networks, and storage resources. The vSphere Client, on the other hand, is a Windows-based client application with a similar purpose but is being phased out in favor of the vSphere Web Client.
True or False: VMWare vSphere supports both Windows and Linux guest operating systems.
True
What is Fault Tolerance (FT) in VMWare vSphere, and how does it provide continuous availability for VMs?
A feature that provides continuous availability for virtual machines by creating a duplicate VM, known as the secondary VM, that runs in parallel with the primary VM. If the primary VM fails, the secondary VM takes over without any interruption.
What is the purpose of a VMWare vSphere Standard Switch, and how does it differ from a Distributed Switch?
Standard Switch is a virtual switch that provides network connectivity within a single ESXi host. It enables virtual machines to communicate with each other and with the physical network. In contrast, a VMWare Distributed Switch (vDS) extends the network connectivity across multiple ESXi hosts, allowing consistent network configuration and management across the hosts in a cluster or datacenter.
How does VMWare vSphere Storage DRS (SDRS) help with automatic storage management?
VMWare vSphere Storage DRS (SDRS) is a feature that automates the management of virtual machine storage resources. It monitors storage capacity, performance, and utilization across datastores and makes recommendations or automatically migrates virtual machine disks to balance the storage load, improve performance, and ensure optimal resource utilization.
What is VMWare vSphere Resource Pools, and how do they help with resource allocation and management?
Logical containers that group virtual machines and manage the allocation of resources such as CPU, memory, and storage. Resource Pools enable administrators to set allocation policies, prioritize resource usage, and manage resource sharing within a cluster, ensuring efficient utilization and fair allocation of resources.
What is the maximum number of virtual CPUs that can be assigned to a single virtual machine in VMWare vSphere?
depends on the version and licensing, but it can go up to 128 vCPUs
How does VMWare vSphere vSAN enhance storage capabilities in a virtualized environment?
A software-defined storage solution that leverages the local storage devices of the ESXi hosts to create a distributed storage pool. It provides scalable, high-performance, and cost-effective storage for virtual machines in a vSphere environment, eliminating the need for external shared storage.
How does VMWare NSX integrate with VMWare vSphere, and what benefits does it provide for network virtualization?
network virtualization and security platform that extends the capabilities of vSphere by providing advanced networking and security services, including micro-segmentation, distributed firewalling, load balancing, and virtual private networks (VPNs). NSX enables the creation of virtual networks and the implementation of network policies independent of physical network infrastructure, bringing agility, automation, and enhanced security to the virtualized environment.
What is VMWare vSphere Virtual Volumes (VVols), and how does it improve storage management and efficiency?
VMWare vSphere Virtual Volumes (VVols) is a storage integration and management framework that provides finer-grained control and management of storage resources at the virtual machine level. It enables policy-based management, data services, and granular control over virtual machine storage, improving storage efficiency, simplifying management, and enhancing VM-centric operations.
How does VMWare vRealize Operations Manager enhance monitoring and performance management in a vSphere environment?
It provides comprehensive visibility, Intelligent analytics, performance optimization through monitoring, capacity planning and management, and integration and extensibility.
