In a vSphere High Availability cluster, what is the VM Monitoring I/O stats interval default value?
A. 60 seconds
B. 90 seconds
C. 120 seconds
D. 180 seconds
Correct Answer: C
Explanation: The I/O stats interval determines if any disk or network activity has occurred for the virtual machine during the previous two minutes (120 seconds). If not, the virtual machine is reset. This default value (120 seconds) can be changed using the advanced attribute das.iostatsinterval.
How does vSphere High Availability calculate the memory slot size of a virtual machine?
A. Virtual machine memory reservation + overhead of largest virtual machine
B. Virtual machine memory reservation - overhead of largest virtual machine
C. Virtual machine memory reservation + overhead of smallest virtual machine
D. Virtual machine memory reservation - overhead of smallest virtual machine
Correct Answer: A
Virtual machine memory reservation + overhead of largest virtual machine Metrics Example: Suppose if :
1.
Memory (2048MB)
2.
Memory Overhead (110.63MB) The first one, Memory, is an easy one. This is the amount of memory you provisioned your VM with, in this case 2048MB. The second field is Memory Overhead. Memory Overhead is the amount of memory the VMkernel thinks it will need to run the virtualized workload, in this case 110.63MB. This typicall would include things like page tables, frame buffers etc.
An administrator wants to set a non-default isolation address of 192.168.1.2 for High Availability.
Which advanced setting would accomplish this task?
A. Das.isolationaddress0=192.168.1.2
B. Das.useisolationaddress0=192.168.1.2
C. Das.defaultisolationaddress0=192.168.1.2
D. Das.haisolationaddress0=192.168.1.2
Correct Answer: A
Explanation: Details In VirtualCenter Server 2.0.2 and above, you can specify more than one isolation response address for VMware High Availability (HA). The use of multiple isolation response addresses offers VMware HA a potentially more accurate picture of the network connectivity of a host. There may be situations in which a single isolation address would indicate that a host is in a state of complete isolation from the network, but access to additional isolation addresses would show that only a partial network failure has occurred. Solution Multiple isolation response addresses can be specified using the das.isolationaddress0 through das.isolationaddress9options.
To specify the values for these options in Virtual Infrastructure Client:
1.
Select the HA cluster.
2.
On the Summary tab, click Edit Settings.
3.
In the Settings dialog, select VMware HA.
4.
Click Advanced Options.
5.
In the Advanced Options (HA) dialog, enter the option name and the corresponding value:
1.
Option: das.isolationaddress0
2.
Value: A valid IP address other than the default gateway address
Similarly, you can set more isolation response addresses using das.isolationaddress1 throughdas.isolationaddress9.
6. In the Advanced Options (HA) dialog box, set this option:
Option: das.usedefaultisolationaddress
Value: false
Notes:
-
You must set this option if you are setting multiple isolation response addresses.
-
Additionally you should configure das.usedefaultisolationaddress to false when the default gateway is a
A vSphere 6.x DRS cluster is configured as shown in the Exhibit.
Based on the exhibit, which statement is true?
A. A virtual machine can be powered on in the Web Resource Pool with a 3 GHz CPU Reservation.
B. A virtual machine can be powered on in the Web Resource Pool with a 4 GHz CPU Reservation.
C. A virtual machine can be powered on in the DB Resource Pool with a 3 GHz CPU Reservation.
D. A virtual machine can be powered on in the DB Resource Pool with a 4 GHz CPU Reservation.
Correct Answer: C
Scaling out (not up) your VMs ie: Don't have one 8 vCPU SQL DB server, use 4 smaller 2vCPU VMs If there is resource contention, RP-QA receives 4GHz and 2GB of memory, and RP-Marketing 2GHz and 1GB. Otherwise, they can receive more than this allotment. Those resources are then available to the virtual machines in the respective resource pools. So now you know better than to use reservations to solve CPU contention. https://pubs.vmware.com/vsphere-6.0
Question 176:
An administrator needs to recover disk space on a previously-used thin provisioned virtual disk. The volumes where the administrator needs to recover the disk blocks are on VAAI-compliant storage arrays.
Which two actions should the administrator take accomplish this task? (Choose two.)
A. Perform a Storage vMotion to another volume in order to force free space recovery to occur. This recreates the volume in a new location and recovers all unused space.
B. Use VMware Converter to migrate the virtual machine to a new datastore. This will recreate the volumes and recover all unused space.
C. Issue the vmkfstools -vmfs unmap command within the VMFS volume directory on the ESXi host console.
D. Execute the esxcli storage vmfs unmap command.
Correct Answer: BD
To reclaim unused storage blocks on a VMFS datastore for a thin-provisioned device, run this command:
An administrator needs to migrate a legacy physical application server to a virtual machine within a vSphere 6 cluster. As part of the conversion, the administrator must reduce the size of the virtual disks.
What action should the administrator take to create a virtual machine with smaller virtual disks than the original physical server?
A. Shut down the physical server and use VMware Converter cold cloning with volume-based cloning at the disk level.
B. Use VMware Converter hot cloning with volume-based cloning at the block level.
C. Shut down the physical server and use VMware Converter cold cloning with volume-based cloning at the file level.
D. Use VMware Converter hot cloning with volume-based cloning at the file level.
Correct Answer: D
Explanation: When reducing the disk volume size, the cloning operation switches from a Block level clone to a File level clone operation, meaning each individual file on the filesystem is copied over to the virtual machines hard drive rather than a block by block image of the drive.
This can cause issues if the filesystem on the source machine is not in good health (for example, if it is severely fragmented, the physical drive has unrecorded bad sectors, or system files are damaged or missing in the index tables of the NTFS file system).
An administrator plans to use VMware Converter Standalone to convert a virtual machine to a vSphere environment. The source virtual machine has these properties:
1.
Running Windows 2008 R2
2.
Contains one NTFS formatted volume
During conversion, how many virtual disks can the administrator add to the destination virtual machine?
A. 0
B. 1
C. 2
D. 3
Correct Answer: A
After adding virtual disk on Windows 2008 and Windows 2008 R2, you cannot make disk online
Windows 2008 and Windows 2008 R2 virtual machine is configured with Virtual Hardware version 7
You see this error within Windows under Disk Management:
The disk is offline because of policy set by an administrator so the virtual disk will show 0.
An administrator is using Auto Deploy to create several ESXi 6.x hosts that will be connected to a vSphere Distributed Switch. After the hosts are deployed, the administrator notices that LACP packets are not being sent between them.
Which statement best describes why this issue is occurring?
A. LACP is not enabled on the vCenter Server.
B. The LACP support settings do not exist in the host profile.
C. The LACP installation bundle is not included in the image profile.
D. LACP has not been configured on the Auto Deploy server.
Correct Answer: B
Explanation: LACP Limitations on a vSphere Distributed Switch Link Aggregation Control Protocol (LACP) on a vSphere distributed switch allows network devices to negotiate automatic bundling of links by sending LACP packets to a peer. However, there are some limitations when using LACP with a vSphere distributed switch.
1.
LACP only works with IP Hash load balancing and Link Status Network failover detection.
2.
LACP is not compatible with iSCSI software multipathing.
3.
vSphere only supports one LACP group per distributed switch, and only one LACP group per host.
4.
LACP settings do not exist in host profiles.
5.
LACP between two nested ESXi hosts is not possible.
Which two are valid compliance results that indicate the need to apply a Host Profile? (Choose two.)
A. Non-compliant
B. Inconsistent
C. Unknown
D. Disconnected
Correct Answer: AC
Explanation: Check Compliance You can confirm the compliance of a host or cluster to its attached Host Profile and determine which, if any, configuration parameters on a host are different from those specified in the Host Profile. Procedure
1.
Navigate to a Host Profile. The Objects tab lists all Host Profies, the number or hosts attached to that Host Profile, and summarized results of the last compliance check.
2.
Click the Check Host Profile Compliance icon ( ). In the Objects tab, the compliance status is updated as Compliant, Unknown, or Non-compliant. A non-compliant status indicates a discovered and specific inconsistency between the profile and the host. To resolve this, you should remediate the host. And unknown status indicates that the compliance of the host could not be verified; to resolve the issue, remediate the host through the Host Profile.
