VMware Fundamentals Exam (part 2) with Complete Solutions

If an ESXi host has 48 GB of memory, can it run 10 VMs which are each configured with 8 GB of memory? - ANSWER-Yes If these 10 VMs each consume 6 GB of memory, what will happen? - ANSWER-Swap file. Use disk space for extra memory. Impact performance If an ESXi host has 16 CPUs, can you create a VM with 32 virtual CPUs? - ANSWER-No. A VM cannot have more virtual CPUs than physical CPUs on the host What are the names of the 3 graphical user interfaces to manage vSphere? - ANSWER--Host Client, -vSphere Client, -vSphere Web Client How do you launch the Host Client to manage an ESXi host directly? I.e., what is the URL? - ANSWER-https://your_ESXi_host/ui How do you launch the Web Client to manage an ESXi host through vCenter? I.e., what is the URL? - ANSWER-https://your_vCenter_Server_Appliance/vsphere-client How do you launch the HTML5 vSphere Client to manage an ESXi host through vCenter I.e., what is the URL - ANSWER-https://your_vCenter_Server_Appliance/ui What is the name of the yellow and dark grey user interface? - ANSWER-DCUI-Direct Console User Interface How do you access this yellow and dark grey user interface? - ANSWER-Press F2 when powering on Host Generally, which is preferred: managing your ESXi host directly, or managing it through vCenter? - ANSWER-Manage through vCenter If you enable Lockdown Mode, can you still remotely log into the ESXi host as the user "root"? - ANSWER-No. Lockdown prevents remote management at the host level. A root user can still long into the host when at the machine unless strict lockdown mode is enabled. Which file contains the VM configuration information? - ANSWER- (configuration file describing VM hardware) What is an uplink? - ANSWER-Virtual switch to Physical port Must a virtual switch have an uplink? - ANSWER-Yes Can a virtual switch have more than one uplink? - ANSWER-Yes Can an uplink be connected to 2 or more virtual switches? - ANSWER-Yes To what on a virtual switch do VMs connect? - ANSWER-Virtual Machine Port Groups Name 3 or more uses for a VM Kernel port. - ANSWER-IP storage, vSphere vMotion migration, VMware vSphere Fault Tolerance Which security policy should be enabled if you run a network sniffer in a VM? - ANSWER-Promiscuous mode Which security policy will not send out Ethernet frames from a VM that has changed its MAC address? - ANSWER-MAC Address Changes Which security policy will not forward Ethernet frames to a VM that has changed its MAC address? - ANSWER-Forged Transmits What policy of a virtual switch or a virtual machine port group will effectively "throttle" a VM that is hogging network bandwidth? - ANSWER-MAC Address Changes What are the 4 kinds of disks or LUNs that can be formatted with VMFS? i.e., through what protocol are they accessed? - ANSWER-Fibre Channel, FCoE, iSCSI, Direct Attached, NAS, NFS Protocol Which of these 4 kinds of disks or LUNs can be shared with other ESXi hosts? - ANSWER-FCoE, iSCSI, Direct Attached, Fibre Channel What 2 networking protocols can be used by ESXi to attach to (connect to) file-based (or NAS) storage? - ANSWER-NFS protocol, VMFS Protocol What Block storage protocols allow for shared storage, and therefore allow for vMotion, HA and DRS? - ANSWER-SCSI Protocol / FCoE / Fibre Channel In addition to NFS and VMFS, what are two other types of datastores? - ANSWER-block & file, SAN & NAS When all of a VM's files are all on a VMFS datastore, can the VM have a raw device mapping? - ANSWER-Yes When all of a VM's files are all on an NFS datastore, can the VM have a raw device mapping? - ANSWER-No When a Windows VM has a raw device mapping, will the Raw Device be formatted with NTFS or VMFS? - ANSWER-VMFS What is the unique identifier on the host called that identifies the iSCSI initiator? - ANSWER-IQN or EUI Where else in the configuration between host and storage array is a unique identifier for iSCSI specified? - ANSWER-Target name of adapter details What happens to the data in an NFS datastore when the datastore is unmounted? - ANSWER-Remains intact but cannot be seen from the specified hosts How large can a VMFS datastore be? - ANSWER-64 TB For what reason(s) might you give a VM an RDM? - ANSWER--A VM is clustered with a physical machine / -disk may be too large; easier to keep as RDM / -VM is using storage array-level snapshot applications What is an overcommitted datastore? - ANSWER-When the total provisioned space of a thin provisioned disk is greater than the size of the datastore What happens to the data in a VMFS datastore when the datastore is deleted? - ANSWER-Datastore is destroyed and deleted from ALL hosts What are the 3 path selection policies (multipathing policies)? - ANSWER-Round Robin, MRU (most recently used), Fixed When a path fails, which path selection policy will fail back (return to the original path) when the failed path returns to service? - ANSWER-MRU Can the disks comprise vSAN be both local disks and SAN LUNs? - ANSWER-Yes For vSAN, a collection of disks on a host is called a _______ - ANSWER-disk group Does the Virtual Volumes feature put VM files on LUNs? - ANSWER-Yes What 2 constructs must the Storage Administrator configure to allow for Virtual Volumes? - ANSWER-Create VM storage policies / deploy VMs with a VM storage policy Can you power-on a template? - ANSWER-No When can you convert a VM to a template? - ANSWER-When it's powered off In the absence of vCenter (i.e., connecting directly to ESXi with the Host Client), can you work with templates and clones? - ANSWER-No When you clone a VM, can the source VM be powered on? - ANSWER-Yes What is the name of the process that makes VMs cloned from a source VM unique? - ANSWER-Customization What attributes of a VM which is a clone must this customization process change? - ANSWER-Computer name, network settings, license settings, Windows Security Identifier When you clone a VM, can the resulting clone have a different virtual disk format? I.e., can the source virtual disk be thin, and the clone be thick? - ANSWER-Yes Can you remove any virtual hardware from a VM that is powered on? - ANSWER-Yes, the hot-pluggable virtual hardware What are the 2 compatibility modes for an RDM? Which one allows you to clone the VM? - ANSWER-Physical and virtual/ virtual If a Windows VM boots from a virtual disk that is 11 GB in size, how large will the C: drive be after you increase the virtual disk to 15 GB? - ANSWER-11 GB Can you shrink a VM's virtual disk? - ANSWER-No What operation turns a thin provisioned virtual disk into a thick provisioned virtual disk? - ANSWER-Inflate Name 4 requirements for vMotion to succeed. - ANSWER-You need shared storage, it has to be able to replicate the SWAP file, compatible CPU's, VMKernel ports and vMotion network have to be setup, hosts configured to use shared VMFS volume Can you vMotion a VM that has a CD .ISO mounted? (The answer is "Yes, if...."; finish the sentence) - ANSWER-Yes, if the ISO is on shared storage Is it possible to migrate a VM from a host using Intel processors to a host using AMD processors? (Careful with your answer) - ANSWER-No What is the term for a vMotion operation when the VM is on a local datastore and you want to move the VM to another host? - ANSWER-Migration Can I vMotion a VM between vCenter instances? - ANSWER-Yes What happens when I delete a snapshot above the bullseye? - ANSWER-Snapshot state is deleted What happens when I delete a snapshot below the bullseye? - ANSWER-Subsequent snapshots are deleted, and you can no longer return to those states
