QUESTION 293
An administrator is configuring a stretched HA configuration and has HA errors on all of the hosts at the remote site.
What can be done to ensure virtual machines at one site can be restarted at the remote site?

A.    Ensure any firewalls between the hosts are allowing port 8182
B.    Create separate HA clusters at each site and enable Stretch Cluster on each
C.    Ensure the latency between the sites is less than 5 milliseconds
D.    Ensure each site has no more than 4 primary hosts

Answer: A
Explanation:
TO make sure virtual machines can be restarted at the remote site, you need to allow port 8182 between the hosts.

QUESTION 294
Click the Exhibit button. An administrator has received reports of poor network performance with a virtual machine.

image
Which task will improve the network performance of this virtual machine?

A.    Adjust shares for the virtual NIC on the virtual machine.
B.    Traffic-shape this virtual machine.
C.    Move the virtual machine to another virtual switch.
D.    Add a CPU to the virtual machine.

Answer: C
Explanation:
One way to improve network performance is to move the virtual machine to another virtual switch. Simple and easy. You can then check the affected vswitch for problems.

QUESTION 295
The performance graph for a virtual machine with 1GB of RAM shows the Swap In rate to be 150 MBps and the Balloon value to be at 0 MB. Users of the virtual machine are complaining that performance is slow.
Which two actions could increase performance of the virtual machine? (Choose two.)

A.    Install the VMMEMCTL driver on the ESXi host.
B.    Increase the memory share value for this virtual machine.
C.    Install VMware Tools into this virtual machine.
D.    Disable swapping in the virtual machine operating system.

Answer: BC
Explanation:
To increase virtual machine performance, you need to install memory share value for this VM.
Install VMware tools as well

QUESTION 296
Which two components can be installed in monitored virtual machines to trigger vSphere HA Application Monitoring? (Choose two.)

A.    A custom script utilizing the appmonitor executable
B.    Tne vSphere Fault Tolerant agent
C.    Third-party utilities such as Neverfail or ApplicationHA
D.    The vSphere HA application agent

Answer: AC
Explanation:
Custom script using appmonitor executable can be installed in monitored VMs that will help triggering vSphere HA Application monitoring. You can also install third-party utilities like Neverfail or ApplicationHA to trigger vSphere HA Application monitoring.

QUESTION 297
What are two considerations when using resource pools in a vSphere cluster? (Choose two.)

A.    Default shares are equal for all sibling resource pools, regardless of virtual machines or child pools
B.    By default, Reservations can be exceeded
C.    vMotion must be setup prior to creating Resource Pools
D.    DRS rules cannot violate Resource Pool membership

Answer: AB

QUESTION 298
A vSphere 5.x implementation contains two ESXi hosts, ESXi01and ESXi02. There is a virtual machine "VM21" connected to the Production port group on ESXi01.
ESXi01 has the following switch configuration.
vSwitch0, single uplink to 10.1.20.0/24
Production port group
VMkernel port for vMotion
VMKernel port for management
vSwitch1, single uplink to 10.1.40.0/24
Engineering port group
VMKernel port for NFS storage
ESXi02 has the following switch configuration.
vSwitch0, single uplink to 10.1.20.0/24
Engineering port group
VMkernel port for vMotion
VMKernel port for management
vSwitch1, single uplink to 10.1.40.0/24
Production port group
VMKernel port for NFS storage
Which two statements are true about this configuration? (Choose two.)

A.    vMotion is not available between the two hosts
B.    If VM21 is migrated to ESXi02 it will not be available on the network
C.    The virtual machine can be vMotion migrated to the target host.
D.    Broadcasts from the Production port group will not reach the Engineering port group.

Answer: BD
Explanation:
If VM21 is migrated to ESXi 02, then according to the information provided, it will not be available on the network. Likewise, broadcasts from production port group will not reach engineering port group.

QUESTION 299
Which settings are required for virtual machine guest tagging for VLAN 100 in a vSphere 5.x environment?

A.    Port Group configured for VLAN 100, physical switch configured as a VLAN trunk
B.    Port Group configured for VLAN 4095, physical switch configured as a VLAN trunk
C.    Port Group configured for VLAN 100, physical switch configured for VLAN 100
D.    Port Group configured for VLAN 4095, physical switch configured for VLAN 100

Answer: B
Explanation:
A VLAN ID, which restricts port group traffic to a logical Ethernet segment within the physical network, is optional. For a port group to reach port groups located on other VLANs, the VLAN ID must be set to 4095. If you use VLAN IDs, you must change the port group labels and VLAN IDs together so that the labels properly represent connectivity.
If you enter 0 or leave the option blank, the port group can see only untagged (non-VLAN) traffic. If you enter 4095, the port group can see traffic on any VLAN while leaving the VLAN tags intact.

QUESTION 300
When you are configuring the NIC teaming policy for a vSwitch, what happens when the Failback option is set to Yes?

A.    A failed uplink will be left inactive upon recovery until another uplink fails.
B.    The vswitch is notified when a failover event occurs.
C.    The physical switches are notified when a failback event occurs.
D.    A failed uplink is returned to active duty immediately upon recovery.

Answer: C
Explanation:
Notify Switches Select Yes or No to notify switches in the case of failover. If you select Yes,
whenever a virtual NIC is connected to the standard switch or whenever that virtual NIC’s traffic would be routed over a different physical NIC in the team because of a failover event, 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. NOTE Do not use this option when the virtual machines using the port group are using Microsoft Network Load Balancing in unicast mode. No such issue exists with NLB running in multicast mode.
