• Question 161:

  Refer to the Exhibit.

  

  An administrator reviews the Health of a virtual machine, as shown in the Exhibit.

  Based on the exhibit, which three metrics can be used to determine the virtual machine's Workload characteristics? (Choose three.)

  A. CPU

  B. Memory

  C. Network I/O

  D. Threads

  E. vNUMA Stats

  Correct Answer: ABC

  Virtual Machine Alert Definitions The vCenter adapter provides alert definitions that are generated on the virtual machines in your environment. Health/Symptom-based These alerts have the following impact and criticality information.

• Question 162:

  Refer to the Exhibit.

  

  The Prod-DB virtual machine has a VM Override as shown in the Exhibit.

  What step, if taken, would require all virtual machines in the cluster to migrate automatically?

  A. Deselect the virtual machine from VM Overrides.

  B. Add all virtual machines to the VM Overrides.

  C. Change Response for Host Isolation to Use Cluster Settings.

  D. Change the Automation level to Use Cluster Settings.

  Correct Answer: D

  To migrate virtual machine in the cluster automatically, you need to change the automation level to use cluster settings. The automation level will then use cluster settings to automatically migrate virtual machines in the cluster.

• Question 163:

  An administrator wants to prevent a priority virtual machine that resides in a vSphere DRS cluster from migrating to other hosts in the cluster.

  What configuration step will accomplish this without affecting other virtual machines?

  A. Set VM Overrides to Partially Automated.

  B. Set VM Overrides to Manual.

  C. Configure a VM/Host Rule with the setting Must run on hosts in group.

  D. Configure a VM/Host Rule with the setting Should run on hosts in group.

  Correct Answer: B

  Option Manual

  Description Placement and migration recommendations are displayed, but do not run until you manually apply the recommendation.

• Question 164:

  Refer to the Exhibit.

  

  An administrator has configured Distributed Resource Scheduler (DRS) groups and Affinity Rules as shown in the Exhibit.

  Based on the exhibit, which two statements are true? (Choose two.)

  A. If ESXi-A and ESXi-D failed, VM-A and VM-B would not failover.

  B. A new conflicting affinity rule will be disabled by default.

  C. VM-B and VM-D can run on the same hosts.

  D. The administrator must disable Rule3 in order to enable Rule4.

  Correct Answer: BD

  B-) NOTE If you use the Specify Failover Hosts admission control policy and designate multiple failover hosts, DRS does not attempt to enforce VM-VM affinity rules for virtual machines that are running on failover hosts. D-) vSphere HA and DRS Affinity Rules If you create a DRS affinity rule for your cluster, you can specify how vSphere HA applies that rule during a virtual machine failover. The two types of rules for which you can specify vSphere HA failover behavior are the following: n VM anti-affinity rules force specified virtual machines to remain apart during failover actions. n VM-Host affinity rules place specified virtual machines on a particular host or a member of a defined group of hosts during failover actions. When you edit a DRS affinity rule, select the checkbox or checkboxes that enforce the desired failover behavior for vSphere HA. n HA must respect VM anti-affinity rules during failover -- if VMs with this rule would be placed together, the failover is aborted. https://pubs.vmware.com/vsphere-60/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-60availability-guide.pdf

• Question 165:

  Which two statements regarding Distributed Resource Scheduler (DRS) affinity rules are true? (Choose two.)

  A. When two VM-VM affinity rules conflict, the older one takes precedence and the newer rule is disabled.

  B. Using Specify Failover Hosts admission control policy, VM-VM affinity rules are not supported.

  C. DRS gives higher precedence to preventing violations of anti-affinity rules than violations of affinity rules.

  D. It is not possible to create an affinity rule that conflicts with the other rules being used.

  Correct Answer: AC

  VM-VM Affinity Rule Conflicts You can create and use multiple VM-VM affinity rules, however, this might lead to situations where the rules conflict with one another. If two VM-VM affinity rules are in conflict, you cannot enable both. For example, if one rule keeps two virtual machines together and another rule keeps the same two virtual machines apart, you cannot enable both rules. Select one of the rules to apply and disable or remove the conflicting rule. When two VM-VM affinity rules conflict, the older one takes precedence and the newer rule is disabled. DRS only tries to satisfy enabled rules and disabled rules are ignored. DRS gives higher precedence to preventing violations of anti- affinity rules than violations of affinity rules.

• Question 166:

  Which two options are available in the Virtual Machine Component Protection (VMCP) setting Response for Datastore with All Paths Down (APD)? (Choose two.)

  A. Issue Events

  B. Power off and restart virtual machines

  C. Reset virtual machines D. Leave Powered On

  Correct Answer: AB

  PDL failures A virtual machine is automatically failed over to a new host unless you have configured VMCP only to Issue events. APD events The response to APD events is more complex and accordingly the configuration is more fine-grained. After the user-configured Delay for VM failover for APD period has elapsed, the action taken depends on the policy you selected. An event will be issued and the virtual machine is restarted conservatively or aggressively. The conservative approach does not terminate the virtual machine if the success of the failover is unknown, for example in a network partition. The aggressive approach does terminate the virtual machine under these conditions. Neither approach terminates the virtual machine if there are insufficient resources in the cluster for the failover to succeed. If APD recovers before the user-configured Delay for VM failover for APD period has elapsed, you can choose to reset the affected virtual machines, which recovers the guest applications that were impacted by the IO failures.

• Question 167:

  Which two settings are required for Virtual Machine Component Protection (VMCP) to protect from All Paths Down (APD) and Permanent Device Loss (PDL)? (Choose two.)

  A. Host Monitoring

  B. VM Restart Priority

  C. Virtual machine Monitoring

  D. Response for Host Isolation

  Correct Answer: AB

  If either the Host Monitoring or VM Restart Priority settings are disabled, VMCP cannot perform virtual machine restarts. Storage health can still be monitored and events can be issued, Reference: https://pubs.vmware.com/vsphere60/index.jsp?topic=%2Fcom.vmware.vsphere.avail.doc%2FGUIDF01F7EB8-FF9D-45E2-A093-5F56A788D027.html

• Question 168:

  A vSphere 6 High Availability cluster has been configured with default settings. Four virtual machines in the cluster have been configured with these priorities:

  1.

  Prod-DB. High

  2.

  Prod-Email: High

  3.

  Prod-VC. Medium

  4.

  Dev-VDI: Low

  How many VM Overrides would need to be defined at the cluster level to meet the restart priorities?

  A. 1

  B. 2

  C. 3

  D. 4

  Correct Answer: B

  After you create a vSphere HA cluster, you can override the default cluster settings for Restart Priority and Isolation Response for specific virtual machines. Such overrides are useful for virtual machines that are used for special tasks. For example, virtual machines that provide infrastructure services like DNS or DHCP might need to be powered on before other virtual machines in the cluster. VM Overrides the default or defined to meet the restart priorities : 2 are HIGH and medium, low respectively hence its 2 overrides at cluster level. https://pubs.vmware.com/vsphere-60/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-60availability-guide.pdf

• Question 169:

  An administrator wants to configure a High Availability cluster to allow virtual machines a 10 minute window to shut down in the event of a Host Isolation incident.

  What two configuration settings would satisfy this requirement? (Choose two.)

  A. Set the advanced option das.isolationshutdowntimeout = 10.

  B. Set the advanced option das.isolationshutdowntimeout = 600.

  C. Configure Host Isolation Response to Shut Down and Restart VMs.

  D. Configure Host Isolation Response to Power Off and Restart VMs.

  Correct Answer: BC

  das.isolationShutdownTimeout The number of seconds an FDM waits for a virtual machine to power off after initiating a guest shutdown before the FDM issues a power off. If the option is unset, 300s is used.

• Question 170:

  An administrator enables High Availability (HA) on a Virtual SAN cluster.

  There are four vmkernel port groups with the following IP addresses assigned:

  1.

  Management: 192.168.12.10

  2.

  vMotion: 192.168.13.10

  3.

  Virtual SAN: 192.168.14.10

  4.

  Fault TolerancE. 192.168.15.10

  Which IP address will HA use for traffic?

  A. 192.168.12.10

  B. 192.168.13.10

  C. 192.168.14.10

  D. 192.168.15.10

  Correct Answer: C

  Give the VMKernel port a label (e.g. iSCSI - if it will purley be used for iSCSI).

  Enter the VLAN ID if the pNICs connected to the vSwitch are trunk ports and you have a specific VLAN for

  this traffic (e.g. a dedicated storage VLAN).

  Now if the port will only be used for storage services (iSCSI and NFS).

  If the port will be used for all VMkernel services (iSCSI, NFS, vMotion and FT), tick the additional boxes to

  allow this port to be used also for those services, Assigned the FT (IP Address)

  Clustering is configured to give you, the administrator of an environment, a form of fault tolerance, and

  VMware has taken this concept to a whole other level. Although VMware does not call FT clustering, it

  functions the same in that FT will failover the primary virtual machine to a secondary virtual machine.

  VMware Fault Tolerance (FT) is based on vLockstep technology and provides zero downtime, zero data

  loss, and continuous availability for your applications.

  Next,

  ?Always assign a reasonably high relative share for the Fault Tolerance

  resource pool because FT is a very latency-sensitive traffic type.
