1) The fixed path multipathing poicy is intended provide:
- Priorty disk I/O requests for high priority vms.
2) New to ESXi 4.0 is round robin multipathing. This path selection policy :
- Distributes Storage I/O’s equally across all paths to a SAN LUN
3) A Resource pool is an inventory object:
- Acts like a folder in the Host and Clusters view but contains resource tunable including cpu and Memory reservations, shares and limits
4) A custom limit set on a vm’s memory is used to:
- Force the VM to live with less than its declared maximum ram…
5) By default a vm gets:
- 100% service from a physical cpu core for each vCPU
6) Accustom limit set on a vm’s memory is used to :
- Force the VM to live with less than its Declared Maximum RAM Any attempt to use more than the limit is handled through vm kernel
7) Vmotion is primarily used to:
- Facilitate esx host maintenance by evacuating the host before taking it down
- Resource balance ESXi hosts by hot moving vms from over-worked esxi hosts to esxi host space resources
8) Vmotion validation can fail because:
- The VM has vNic with a defined connection to an internal only vSwitch but it is disconnected
9) Following is NOT a requirement for successful VMotion of a VM:
- The VM must reside on a Raw Disk Map
10) The Datastore browser can be used to add a power off vm to your esxi hosts inventory :
- Righ Click on the vm’s vmx file and select add to inventory.
11) A vSwitch Port Group is a named collection vSwitch ports used for :
- vm to everything
12) Vcenter Link Mode is a new feature that:
- links secondary vCenter installation into a primary vCenter installation for improved vCenter availability and
scalability.
13) In Vmware terminology, a Thick provisioned disk is a :
- Virtual disk that is fully allocation to it’s declared size
14) ESXi Power management, if configured, lets ESXi :
- Turn off unneeded power supplies on the physical server
15) The purpose of limiting the number of VM consoles vCenter will proxy to vSphere clients is to :
- Comply with the license conditions imposed by the license installed on your esxi server
16) ESXi licensing :
- must be established within 60 days of installation or powered off vms will not power on.
17) A physical nic on the same ESXi host
- can be shared across multiple vNetwork standard vSwitches
18) Esxi 4.1 run on :
- either intel or AMD 64-bit CPUs only
19) When installing esxi onto local storage, your local storage volume is :
- Completely overwritten, destroying any existing partitions except vendor supplied partition
20) Cold Migration is the act of:
- Moving a powered off vm from on esxi host to another / moving a powered off
VM from one ESXi host and or datastore to another ESXi host
21) Bare metal vitalization is superior to hosted virtualization because esx/esxi :
- Owns all resources / Everything
22) The maximum number of esxi addressable san luns is :
- 256
23) Challenge handshake authentication protocol (CHAP) can be used :
- For either ESXi to SAN or for SAN to ESXi authentication or both
24) The esxi host mounts point for a vmfs volume with the value label Database is:
- /vmfs/volumes/Database
25) The maximum file size of a file on a a VMFS volume is determined by :
- The block size of the VMFS, set when the vmfs was first created
26) A DvUplink ports ona vNetwork Distributed vSwitch are used to:
- plink an ESXi hosts dvSwith to a physical network segment so that frames may be exchanged between esxi hosts who are member of the common dvswitch
27) The traffic shaping, Peak Bandwidth refers to:
- A hard limit set on the maximum bandwidth that can be consumed for network traffic flowing through a port or
port group
28) With ISCSI sans, you can boot from SAN only if you :
- use iscsi hardware initiators
29) Setting the promiscuous mode security policy to reject:
- causes a vswitch port group to drop inboud frames where the destination MAC address of a frame does not match the target vms vnic mac address
30) Vnetwork distributed virtual switches are:
- a vswitch created / managed by vcenter that may span multiple esxi hosts.
31) VNetwork distributed virtual switches may be used for:
- everything
32) Vmware data recovery can:
- Recover individual VMvirtual disk
33) When diagnosing poor VM CPU performance, the metric you should focus on is :
- CPU Ready (the amount of time a vCPU waits for service)
- CPU Idle (the amount of time a vCPU spends running the guest OS idle task)
34) Vmware update manager can patch and updates :
- ESXi and ESX hosts only
35) Vmware esx/esxi virtualization, technology virtualizes :
- At the physical server level ESXi gives VMs virtual hardware, vms do not see or use physical hardware directly
36) The VSphere license that entitles you to use “All” available vSphere features is :
- vSphere Enterprise Plus
37) Cloud computing is a term that is used to indicate:
- Server, network and storage abstraction that reduces the cost, time and complexity of server deployments
38) VMware vSphere licenses have hardware limits built-in:
- CPU cores and Maximum memory use
39) Esxi should be configured to use network time protocol because :
- NTP keeps Esxi clock accurate which is then be used to keep VM clocks accurate
40) It is a good idea to join esxi to a windows domain because:
- you can not join ?? to windows domain.
41) VMware uses strong encryption:
- Between all vmware server software
42) vNetwork Distributed virtual switches :
- available in vsphere enterprise plus and are fully supported in production
43) vmkernel ports are used by the esxi for :
- Management, vmotion , fault tolerance, iscsi and for NFS traffic
