Introduction to VMware vSphere
o vCompute – aggregate resources
o vStorage – enables the most efficient use and management of storage
o vNetwork – simplify and enhance networking
o Fault Tolerance – a secondary VCP-410 copy. Actions completed on the primary VM are also applied to the secondary VM. If the primary VM becomes
unavailable, the secondary machine becomes active, providing continual availability.
o Distributed Virtual Switch (DVS) – spans many hosts reduction of maintenance and increasing network capacity.
o Host Profiles – host configuration management through user-defined configuration policies. Captures the blueprint and monitors compliance.
o Pluggable Storage Array (PSA) – greater array certification flexibility and improved array-optimized performance. A multipath I/O framework.
o Cluster – aggregate computing and memory resources of a group of physical x86 servers sharing the same network and storage arrays.
o Resource pools – partitions of computing and memory resources from a single host or a cluster. can be hierarchical and nested.
o Storage VMotion – enables the migration of VMs from one datastore to another datastore without service interruption
o Fault Tolerance (FT) – uses vLockstep technology, continuous availability by protecting a VM (the Primary VM) with a shadow copy (Secondary
VM) that runs in virtual lockstep on a separate host.
o vNetwork Distributed Switch (dvSwitch) – functions as a single virtual switch across all associated hosts.
o dvPort (distributed virtual port) – a port on a DVS that connects to a host’s service console or VMkernel or to a VM’s network adapter.
o vApp – has the same basic operation as a VM, but can contain multiple VMs or appliances.
o Web Access cannot be used to access a host running ESXi 4.0.
o Web Access is turned off by default for ESX hosts.
Getting Started with ESX
o ESX Service Console is held in the esxconsole.vmdk partition.
o vCenter Server uses Microsoft SQL Server 2005 Express for small deployments with up to 5 hosts and 50 VMs.
o If SQL Native Client is already installed, uninstall SQL Native Client before you begin the vCenter Server installation.
o vCenter server must belong to a VCP-410 braindump domain rather than a workgroup. Otherwise it’s not able to discover – using such features as vCenter Guided
Consolidation Service. The computer name cannot be more than 15 characters.
o vCenter Server cannot be an Active Directory domain controller.
o The Domain user account should have the following permissions:
o Member of the Administrators group
o Act as part of the operating system
o Log on as a service
ESX and vCenter server installation guide
o ESX4 will only install and run on servers with 64-bit x86 CPUs. They require a 2GB RAM minimum.
o vCenter Server must have 2 CPUs and 3GB RAM.
o The vCenter Server has a service called VMware VirtualCenter Management Webservices. This service requires 128MB to 1.5GB of additional
memory.
o You can use a 32-bit Windows for up 200 hosts. A 64-bit Windows can have 200-300 hosts.
o The vSphere Client requires the Microsoft .NET 3.0 SP1 Framework.
o vCenter server required firewall ports:
Port Description
80 Redirects requests to HTTPS port 443.
389 LDAP port number for the Directory Services for the vCenter Server group. Needs to bind to port 389, even if you are not joining this
vCenter Server instance to a Linked Mode group.
443 Listen for connections from the vSphere Client.
636 For vCenter Linked Mode, this is the SSL port of the local instance
902 Uses to send data to managed hosts. Managed hosts also send a regular heartbeat over UDP port 902 to the vCenter
902/903 Ports used by vSphere Client to display VM consoles.
8080 Web Services HTTP. Used for VCP-410 exam the VMware VirtualCenter Management Webservices.
8443 Web Services HTTPS. Used for the VMware VirtualCenter Management Webservices.
o If ESX will not use an NTP server, make sure that the server hardware clock is set to UTC in the BIOS (EDIT: As a matter of best practice you
should always set ESX server’s hardware clocks to UTC)
o IPv6 is not supported for ESX installation
o The service console must be installed on a VMFS datastore that is resident on a host’s local disk or on a SAN disk that is masked and zoned to
that particular host only.

o You cannot use IDE/ATA drives to store virtual machines.
o Use local SATA storage, internal and external, in unshared mode only.
o Some SAS storage systems can offer shared access
o You can have up to 256 VMFS datastores per system, with a minimum volume size of 1.2GB.
o Grow the existing datastore VCP-410 exam extent if the storage device where your datastore resides has free space. You can grow the extent up to 2 TB.
o You can connect up to 32 hosts to a single VMFS volume. (EDIT: Maximums document says 64)
o Perform a rescan each time you:
o Create new LUNs on a SAN.
o Change the path masking on a host.
o Reconnect a cable.
o Make a change to a host in a cluster.
o Do not rescan when a path is unavailable.
o To rescan adapters on all hosts managed by vCenter by right-clicking a datacenter, cluster, or folder and selecting Rescan for Datastores.
o ESX does not support the delegate user functionality that enables access to NFS volumes using non-root credentials
o Disk format on a NAS device is dictated by the NFS server, typically a thin format that requires on-demand space allocation.
o When your host accesses a virtual machine disk file on an NFS-based datastore, a .lck-XXX lock file is generated to prevent other hosts from
accessing this file.
o If the underlying NFS volume, is read-only, make sure that the volume is exported as a read-only share by the NFS server, or configure it as a
read-only on the ESX host.
o A diagnostic partition cannot be located on an iSCSI LUN accessed through a software iSCSI initiator.
o You can query and scan the host’s diagnostic partition using the vicfg-dumppart -l command
o You can group datastores into folders.
o You can unmount:
o NFS datastores
o VMFS datastore copies mounted without resignaturing
o You can have up to 32 extents.
o You can grow an extent in an existing VMFS datastore. Only extents with free space immediately after them are expandable.
o If a shared datastore has VCP-410 exam questions powered on virtual machines and becomes 100% full, you can increase the datastore’s capacity only from the host,
with which the powered on virtual machines are registered.
o You can mount a VMFS datastore only if it does not collide with an already mounted VMFS datastore that has the same UUID (signature).
o When resignaturing a VMFS copy, ESX assigns a new UUID and a new label to the copy, and mounts the copy as a datastore distinct from the
original.
o The default format of the new label assigned to the datastore is snap–, where is an integer and is the
label of the original datastore.
o Datastore resignaturing is irreversible.
o A spanned datastore can be resignatured only if all its extents are online.
o Pluggable Storage Architecture (PSA) is an open modular framework that coordinates the simultaneous operation of multiple multipathing
plugins (MPPs). The VMkernel multipathing plugin that ESX provides by default is the VMware Native Multipathing Plugin (NMP). Two types of
NMP subplugins, Storage Array Type Plugins (SATPs), and Path Selection Plugins (PSPs).
o The VMware NMP supports all storage arrays listed on the VMware storage HCL and provides a default path selection algorithm based on the
array type.
o ESX offers an SATP for every type of array that VMware supports.
o By default, the VMware NMP supports the following PSPs:
o Most Recently Used (MRU)
o Fixed - with active-passive arrays that have a Fixed path policy, path thrashing might be a problem.
o Round Robin (RR) - Uses a path selection algorithm that rotates through all available paths enabling load balancing across the paths.
o Claim rules defined in the /etc/vmware/esx.conf file, the host determines which multipathing plugin (MPP) should claim the paths.
o By default, the host performs a periodic path evaluation every 5 minutes.
o Active multiple working paths currently used for transferring data are marked as Active (I/O). In ESX 3.5 or earlier, the term active means the
only path that the host is using to issue I/O to a LUN.
o Standby path is operational VCP-410 study guide and can be used for I/O if active paths fail.
o If you created a virtual disk in the thin format, you can later inflate it to its full size.
o RDM offers several benefits. User-Friendly Persistent Names, Dynamic Name Resolution, Distributed File Locking, File Permissions, File System
Operations, Snapshots, vMotion, SAN Management Agents and N-Port ID Virtualization(NPIV).
o Certain limitations exist when you use RDMs:
o Not available for block devices or certain RAID devices.
o Available with VMFS-2 and VMFS-3 volumes only.
o No snapshots in physical compatibility mode.
o No partition mapping. It requires a whole LUN.

10. Once vCenter 4.x has been installed, a License Server is required in which of the following instances?
A. A License Server is always required
B. To support ESXi 4.x Hosts
C. To support ESX 3.5 Hosts
D. A License Server is no longer required

Answer: C

o MAC Address Changes - the guest OS changes the MAC address of the adapter to anything other than what is in the .vmx
o Forged Transmits - Outbound frames with a source MAC address that is different from the one set on the adapter are dropped.
o Traffic shaping
o Traffic shaping policy is defined VCP-410 exam questions by three characteristics: average bandwidth, peak bandwidth, and burst size.
o ESX shapes outbound network traffic on vSwitches and both inbound and outbound traffic on a vNetwork Distributed Switch.
o Peak bandwidth cannot be less than the specified average bandwidth.
o NIC Teaming (Load balancing and failover)
o Load Balancing
1. Route based on the originating port ID — Choose an uplink based on the virtual port where the traffic entered the virtual
switch.
2. Route based on ip hash — Choose an uplink based on a hash of the source and destination IP addresses of each packet.
3. Route based on source MAC hash — Choose an uplink based on a hash of the source Ethernet.
4. Use explicit failover order — Always use the highest order uplink from the list of Active adapters which passes failover
detection criteria.
o IP-based teaming requires that the physical switch be configured with etherchannel. For all other options, etherchannel should
be disabled.
o Incoming traffic is controlled by the load balancing policy on the physical switch
o Network failover detection
o Link Status only
o Beacon probing - Do not use beacon probing with IP-hash load balancing.
o Notify Switches - a notification is sent out over the network to update the lookup tables on physical switches. In almost all cases, this
process is desirable for the lowest latency of failover occurrences and migrations with VMotion. Do not use this option when the
virtual machines using the port group are using Microsoft Network Load Balancing in unicast mode.
o Failback - determines how a physical adapter is returned to active duty after recovering from a failure. If failback is set to Yes
(default), the adapter is returned to active duty immediately upon recovery.
o Failover Order
1. Active Uplinks
2. Standby Uplinks
3. Unused Uplinks
o When using IP-hash load balancing, do not configure standby uplinks.
o VLAN - The VLAN policy allows VCP-410 study guide virtual networks to join physical VLANs - vNetwork Distributed Switch only (dvPorts).
o Port blocking policies - vNetwork Distributed Switch only (dvPorts).
o VMware uses the Organizationally Unique Identifier (OUI) 00:50:56 for manually generated addresses. You must set them in a virtual
machine’s configuration file: ethernet.addressType=”static”
o Jumbo frames must be enabled at the host level using the command-line interface to configure the MTU size for each vSwitch.
o TCP Segmentation Offload (TSO) is enabled on the VMkernel interface by default, but must be enabled at the virtual machine level.
o To enable TSO at the virtual machine level, you must replace the existing vmxnet or flexible virtual network adapters with enhanced vmxnet
virtual network adapters. This might result in a change in the MAC address of the virtual network adapter.
o To check whether TSO is enabled on a particular VMkernel networking interface use the esxcfg-vmknic -l command. The list shows
each TSO-enabled VMkernel interface with TSO MSS set to 65535.
o If TSO is not enabled for a particular VMkernel interface, the only way to enable it is to delete the VMkernel interface and recreate the
interface.
o Jumbo frames up to 9kB (9000 bytes) are supported.
o Use the vicfg-vswitch -m command to set the MTU size for the vSwitch.
o Enabling jumbo frame support on a virtual machine requires an enhanced vmxnet adapter for that virtual machine.
o NetQueue in ESX takes advantage of the capability of some network adapters to deliver network traffic to the system in multiple receive
queues that can be processed separately. This allows processing to be scaled to multiple CPUs, improving receive-side networking
performance.
o NetQueue is enabled by default.
o ESX supports a direct PCI device connection for virtual machines running on Intel Nehalem platforms. Each virtual machine can connect to up
to 2 passthrough devices.
o The following features are VCP-410 questions unavailable for virtual machines configured with VMDirectPath:
o VMotion
o Hot adding and removing of virtual devices
o Suspend and resume
o Record and replay
o Fault tolerance
o High availability
o DRS (limited availability; the virtual machine can be part of a cluster, but cannot migrate across hosts)
o Software-initiated iSCSI is not available over 10GigE network adapters in ESX.
