Which of 9L0-403 the following statements are true about network traffic shaping? (Choose Two.)
A. The settings affect only outbound traffic.
B. The settings affect only inbound traffic.
C. The settings are defined on a per port group basis.
D. The settings affect inbound and outbound traffic.

Answer: A,C
Explanation:
“defined on a per port group basis. ” could be considered a correct answer because
according to the VMWare Infrastructure 3:Install and Configure guide, “Traffic shaping
may be defined at the virtual switch OR Port Group level. ” The important distinction
here is that they can be defined at this level, but they 9L0-510 are APPLIED on a per-virtual
machine basis or more directly, to the VM’s virtual NIC’s.

VMware HA Attributes:

o das.failuredetectiontime
o das.failuredetectioninterval
o das.isolationShutdownTimeout
o On ESX hosts, HA communications travel over service console networks.
o On ESXi hosts, HA communications travel over VMkernel networks.
o HA needs and automatically opens the following firewall ports:
o Incoming port: TCP/UDP 8042-8045
o Outgoing port: TCP/UDP 2050-2250
o VMware Fault Tolerance provides continuous availability for virtual machines by creating and maintaining a Secondary VM that is 640-802 identical to,
and continuously available to replace, the Primary VM in the event of a failover situation.
o A fault tolerant VM and its secondary copy are not allowed to run on the same host. Fault Tolerance uses anti-affinity rules.
o Fault Tolerance prerequisites:
o VMware HA must be enabled on the cluster. Host Monitoring should also be enabled.
o Host certificate checking must be enabled for all hosts.
o Each host must have a VMotion and a Fault Tolerance Logging NIC configured.
o Hosts must have the same version and patch level.
o Hosts must have processors from the FT-compatible processor group.
o Hosts must have Hardware Virtualization (HV) enabled in the BIOS.
o Virtual machines must be stored in virtual RDM or VM disk (VMDK) files that are thick provisioned with the Cluster Features option.
o Virtual machines must be running on one of the supported guest operating systems.

Appendix – Fault Tolerance Error Messages
vSphere Web Access Administrator’s Guide
o Supported Operating Systems:
o Windows 2003 SP1, XP Pro SP3, XP Home SP2, 2000 SP4
o Linux with standard libraries, but requiring GTK+ 2.
o Supported browsers:
o IE 6, 7 or later
o Firefox 2, 3.0 or later
o The console webAccess service is now vmware-webAccess
o The Alarms tab is available only when you use vSphere Web Access to connect to vCenter Server.
o You can view the assigned tasks for a virtual machine, but you cannot assign tasks using Web Access.
o New disk policy (not available option from vSphere Client)
o Optimize for safety – Saves all changes to the virtual disk before notifying the system.

Periodically (every two seconds by default), the system examines the loads of the various nodes and determines if it should rebalance the load
by moving a virtual machine from one node to another.
o Transparent page sharing has also been optimized for use on NUMA systems.
o The VMkernel.Boot.sharePerNode option controls whether memory pages can be shared (de-duplicated) only within a single NUMA node or
across multiple vcp 4 NUMA nodes. It is turned on by default.
o If you turn off the option, identical pages can be shared across different NUMA nodes. In memory-constrained environments, such as VMware
View this could be very beneficial.
o The systems that offer a NUMA platform include AMD CPUs or the IBM Enterprise X-Architecture.
o You must manually select the boxes for all processors in the NUMA node. CPU affinity is specified on a per-processor, not on a per-node, basis.
o Specify nodes to be used for future memory allocations only if you have also specified CPU affinity.
Appendix A - Performance Monitoring Utilities: resxtop and esxtop
o The esxtop utility reads its default configuration from .esxtop4rc.
o Do not edit the .esxtop4rc file. Instead, select the fields and the order in a running esxtop process, make changes, and save this file using
the W interactive command.
Appendix B – Advanced attributes
vSphere Availability Guide
o The first five hosts added to the cluster are designated as primary hosts, and all subsequent hosts are designated as secondary hosts. The
primary hosts maintain and replicate all cluster state and are used to initiate failover actions. If a primary host is removed from the cluster,
VMware HA promotes another host to primary status.
o One of the primary hosts is also designated as the active primary host and its responsibilities include:
o Deciding where to restart virtual machines.
o Keeping track of failed restart attempts.
o Determining when it is appropriate to keep trying to restart a virtual machine.
o If the active primary host fails, another primary host replaces it.
o If a host stops receiving heartbeats from all other hosts in the cluster for more than 12 seconds, it attempts to ping its isolation addresses. If
this also fails, the host declares itself as isolated from the network.
o Three types of admission control:
o Host
o Resource pool
o HA
o Only VMware HA admission control can be vmware vcp 4 disabled.
o Slot size is a logical representation of the memory and CPU resources that satisfy the requirements for any powered-on virtual machine in the
cluster.
o The maximum Configured Failover Capacity that you can set is four.
o If your cluster contains any virtual machines that have much larger reservations than the others, they will distort slot size calculation. To avoid
this, you can specify an upper bound for the CPU or memory component of the slot size by using the das.slotCpuInMHz or das.slotMemInMB
advanced attributes, respectively.
o You can configure VMware HA to perform admission control by reserving a specific percentage of cluster resources for recovery from host
failures.
o You can configure VMware HA to designate a specific host as the failover host.
o To ensure that spare capacity is available on the failover host, you are prevented from powering on virtual machines or using VMotion to
migrate virtual machines to the failover host.
o When choosing an admission control policy, you should consider a number of factors:
o Avoiding Resource Fragmentation - The Host Failures Cluster Tolerates policy avoids resource fragmentation by defining a slot as the
maximum virtual machine reservation. The Percentage of Cluster Resources policy does not address the problem of resource
fragmentation. With the Specify a Failover Host policy, resources are not fragmented because a single host is reserved for failover.
o Flexibility of Failover Resource 640 802 Reservation - The Host Failures Cluster Tolerates policy allows you to set the failover level from one to four
hosts. The Percentage of Cluster Resources policy allows you to designate up to 50% of cluster resources for failover. The Specify a
Failover Host policy only allows you to specify a single failover host.
o Heterogeneity of Cluster - In a heterogeneous cluster, the Host Failures Cluster Tolerates policy can be too conservative because it only
considers the largest virtual machine reservations when defining slot size and assumes the largest hosts fail when computing the Current
Failover Capacity. The other two admission control policies are not affected by cluster heterogeneity.

A new ESX Server is set up initially with two virtual machines (VMs) for users to access.
The applications will allocate all the memory that is available to them. 20 identical VMs

Two)
A. Create a virtual machine template
B. Migrate a virtual machine with VMotion
C. Adding hardware to a virtual machine
D. Delete a virtual machine

Answer: A,B

ESX/ESXi uses at least 50MB of system memory for the VMkernel. This is not configurable. It depends on the number and type of PCI devices.
An ESXi host uses additional system memory for management agents.
o The service console typically uses 272MB.
o Memory activity is monitored to estimate the working set sizes for a default period of 60 seconds.
o ESX/ESXi charges more for idle memory than for memory that is in use. This is done to help prevent virtual machines from hoarding idle
memory.
o Hosts can reclaim memory from virtual machines using:
o Memory balloon driver (vmmemctl) - VCP-410 Real Exam Questions collaborates with the server to reclaim pages that are considered least valuable by the guest
operating system. Closely matches the behavior of a native system under similar memory constraints. Causes the guest to use its own
native memory management algorithms. You must configure the guest operating system with sufficient swap space.
o Swap Files - hosts use swapping to forcibly reclaim memory from a virtual machine when the vmmemctl driver is not available or is not
responsive. You must reserve swap space for any unreserved virtual machine memory (the difference between the reservation and the
configured memory size) on per-virtual machine swap files.
o If you are overcommitting memory, to support the intra-guest swapping induced by ballooning, ensure that your guest operating systems also
have sufficient swap space. This guest-level swap space must be greater than or equal to the difference between the virtual machine’s
configured memory size and its Reservation.
o Many workloads present opportunities for sharing memory across virtual machines.
o To determine the effectiveness of memory sharing use resxtop or esxtop to observe the actual savings. The PSHARE field of the interactive
mode in the Memory page.
o You measure guest physical memory using the Memory Granted metric (for a virtual machine) or Memory Shared (for an ESX/ESXi host). To
measure machine memory, however, use Memory Consumed (for a virtual machine) or Memory Shared Common (for an ESX/ESXi host).
o The VMkernel maps guest physical memory to machine memory.
o Multiple regions of guest physical memory might be mapped to the same region of machine memory (in the case of memory sharing) or
specific regions of guest physical memory might not be mapped to machine memory (when the VMkernel swaps out or balloons guest physical
memory)
o Resource Pool Hierarchy can have Parents, Children, and Siblings.
o Resource Pool Admission Control - Before you power on a virtual machine or create a resource pool, check the CPU Unreserved and Memory
Unreserved fields in the resource pool’s Resource Allocation tab to determine whether sufficient resources are available.
o A group power on will power on multiple virtual machines Passed VCP 4 at the same time.
o VMotion does not support raw disks or migration of applications clustered using Microsoft Cluster Service (MSCS).
o Other VMware products or features, such as VMware vApp and VMware Fault Tolerance, might override the automation levels of virtual
machines in a DRS cluster.
o An affinity rule specifies that two or more virtual machines be placed on the same host. An anti-affinity DRS rule is limited to two virtual
machines,
o If two rules conflict, the older one will take precedence, and the newer rule is disabled.
o Disabled rules are ignored. DRS gives higher precedence to preventing violations of anti-affinity rules than violations of affinity rules.
o When a host machine is placed in standby mode, it is powered off.
o Hosts are placed in standby mode by the VMware DPM feature
o A cluster becomes overcommitted (yellow) when the cluster does not have the capacity to support all resources reserved by the child resource
pools. Typically this happens when cluster capacity is suddenly reduced.
o A cluster enabled for DRS becomes invalid (red) when the tree is no longer internally consistent, that is, resource constraints are not observed.
o VMware DPM can use one of three power management protocols
o IPMI - Intelligent Platform Management Interface
o iLO - Hewlett-Packard Integrated Lights-Out
o WOL - Wake-On-LAN
o If a host supports multiple protocols, they are used in the following order: IPMI, iLO, WOL.
o The VMotion NIC on each host must support WOL to use that protocol.
o The DRS threshold and the VMware DPM threshold are essentially independent. You can differentiate the aggressiveness of the migration and
host-power-state recommendations.
o Verify that DPM is functioning properly by viewing each host’s Last Time Exited Standby information.
o The most serious potential error you face when using VMware DPM is the failure of a host to exit standby mode when its capacity is needed
by the DRS cluster. Use the preconfigured Exit Standby Error alarm for this error.
o DRS Recommendations have 5 levels (1-5). Priority 1, the highest, indicates a mandatory move because of a host entering maintenance or
standby mode or vcp 410 DRS rule violations. Other priority ratings denote how much the recommendation would improve the cluster’s performance;
o Prior to ESX/ESXi 4.0, recommendations received a star rating (1 to 5 stars) instead of a priority level.
o Non-Uniform Memory Access (NUMA) systems are advanced server platforms with more than one system bus.
o Some virtual machines are not managed by the ESX/ESXi NUMA scheduler: if you manually set the processor affinity for a virtual machine, or
virtual machines that have more virtual processors than the number of physical processor cores available on a single hardware node.
o When a virtual machine is powered on, ESX/ESXi assigns it a home node. This is initially assigned to home nodes in a round robin fashion.
