An administrator is attempting to configure Storage I/O Control (SIOC) on five datastores within a vSphere environment. The administrator is being asked to determine why SIOC configuration completed successfully on only four of the datastores.
What are two possible reasons why the configuration was not successful? (Choose two.)
The datastore contains Raw Device Mappings (RDMs).
SAS disks are used for the datastore.
The datastore has multiple extents.
The datastore is using ISCSI.
The administrator is using NFS storage.
Answers are;
A. The datastore contains Raw Device Mappings (RDMs).
C. The datastore has multiple extents.
Two possible reasons why Storage I/O Control (SIOC) configuration might not be successful on a datastore are:
A. The datastore contains Raw Device Mappings (RDMs): SIOC does not work with datastores containing Raw Device Mappings.
C. The datastore has multiple extents: SIOC is not supported on datastores with multiple extents.
SIOC is generally compatible with different storage types, including ISCSI and NFS, as long as they meet the other requirements and constraints of SIOC. The type of disks (e.g., SAS) typically doesn't affect SIOC configuration.
An administrator is creating a content library to manage VM templates and ISO images. The administrator wants to password-protect the images and templates and share them with a remote site.
Which two tasks must the administration perform when creating the content library? (Choose two.)
Publish the local content library.
Enable the security policy.
Create a subscribed content library.
Select an NFS datastore.
Enable authentication.
Answers are;
A. Publish the local content library.
E. Enable authentication.
You enable authentication to password protect a content library. The security policy is to protect and enforce strict validation while importing an synchronizing OVF library items.
An administrator successfully installs VMware ESXi onto the first host of a new vSphere cluster but makes no additional configuration changes. When attempting to log into the vSphere Host Client using the Fully Qualified Domain Name (FQDN) of the host, the administrator receives the following error message: “Server Not Found – We can’t connect to the server at esxi101.corp.local.”
The following information has been provided to complete the configuration:
Host FQDN: esxi101.corp.local
Management VLAN ID: 10
DHCP: No
Management IP Address: 172.16.10.101 / 24
Management IP Gateway: 172.16.10.1
Corporate DNS Servers: 172.16.10.5, 172.16.10.6
ONS Domain: corp.local
In addition, all host configurations must also meet the following requirements:
The management network must use only IPv4 network protocols.
The management network must be fault tolerant.
Which three high level tasks should the administrator complete, at a minimum, in order to successfully log into the vSphere Host Client using the FQDN for esxi101 and complete the configuration? (Choose three.)
Ensure a DNS A Record is created for the VMware ESXi host on the corporate DNS servers.
Update the VMware ESXi Management Network DNS configuration to use the corporate DNS servers for names resolution.
Update the VMware ESXi Management Network IPv4 configuration to use a static a IPv4 address.
Configure at least two network adapters for the VMware ESXi Management Network.
Set the value of the VMware ESXi Management Network VLAN ID to 10.
Disable IPv6 for the VMware ESXi Management Network.
Answers are;
A. Ensure a DNS A Record is created for the VMware ESXi host on the corporate DNS servers.
B. Update the VMware ESXi Management Network DNS configuration to use the corporate DNS servers for names resolution.
C. Update the VMware ESXi Management Network IPv4 configuration to use a static a IPv4 address.
E. Set the value of the VMware ESXi Management Network VLAN ID to 10.
The question says as the initial configuration, later you'll do the all requirements.
A - You need the dns record to enter the configuration via gui
C - The esxi has to have an ip address
E - The management interafce must to have the vlan 10
The other options are only to do all requirements, but the question is only for the initial.
The answer is correct based on what is the minimum requirement to log into the host client using the FQDN. B is not required just to log into the host client, you could set that later.
Question 24
An administrator is tasked with applying updates to a vSphere cluster running vSAN using vSphere Lifecycle Manager. Downtime to the ESXi hosts must be minimal while the work is completed.
The administrator has already completed the following steps and no errors have been returned:
Downloaded all applicable software and created a new image.
Attached the new image to the cluster and run a compliance check against the image for the cluster.
Ran a remediation pre-check for the cluster.
Which two series of steps should the administrator perform to start the remediation of the cluster using the new image? (Choose two.)
1. Use the Remediate option in vSphere Lifecycle Manager to remediate all of the ESXi hosts in the cluster in parallel. 2. Allow vSphere Lifecycle Manager to automatically control maintenance mode on the ESXi hosts.
1. Place each of the ESXi hosts into maintenance mode manually. 2. Use the Stage option in vSphere Lifecycle Manager to stage the required software on all ESXi hosts one at a time.
1. Leave all ESXi hosts in the cluster operational. 2. Use the Stage All option in vSphere Lifecycle Manager to stage the required software onto all ESXi hosts one at a time.
1. Leave all ESXi hosts in the cluster operational. 2. Use the Stage All option in vSphere Lifecycle Manager to stage the required software onto all ESXi hosts in the cluster in parallel.
1. Use the Remediate option in vSphere Lifecycle Manager to remediate all of the ESXi hosts in the cluster in sequence. 2. Allow vSphere Lifecycle Manager to automatically control maintenance mode on the ESXi hosts.Most Voted
Answers are;
D. 1. Leave all ESXi hosts in the cluster operational.
2. Use the Stage All option in vSphere Lifecycle Manager to stage the required software onto all ESXi hosts in the cluster in parallel.
E. 1. Use the Remediate option in vSphere Lifecycle Manager to remediate all of the ESXi hosts in the cluster in sequence.
2. Allow vSphere Lifecycle Manager to automatically control maintenance mode on the ESXi hosts.Most Voted
By default, vSphere Lifecycle Manager performs the staging operation onto all hosts in the cluster in parallel.
Staging operation in vSphere 8 will not required to put ESXi in maintenance mode.
A vSphere cluster has the following configuration:
Virtual machines (VMs) are running Production and Test workloads vSphere Distributed Resource Scheduler (DRS) is enabled
There are no resource pools in the cluster
Performance monitoring data shows that the Production workload VMs are not receiving their fully allocated memory when the vSphere cluster is fully utilized.
A combination of which two steps could the administrator perform to ensure that the Production VMs are always guaranteed the full allocation of memory? (Choose two.)
Assign a custom memory share value to the resource pool containing the Production VMs.
Assign a memory reservation value to the resource pool containing the Production VMs.
Create a parent resource pool for the Production VMs.
Create a sibling resource pool for each of the Production and Test VMs.
Create a child resource pool for the Test VMs.
Answers are;
B. Assign a memory reservation value to the resource pool containing the Production VMs.
D. Create a sibling resource pool for each of the Production and Test VMs.
B. Assigning a memory reservation value to the resource pool containing the Production VMs ensures that a specific amount of memory is reserved exclusively for those VMs. This means that even in situations of high contention for resources, the Production VMs will receive their full memory allocation.
D. Creating a sibling resource pool for each of the Production and Test VMs may not address the issue of memory allocation either. Sibling resource pools are at the same level in the resource pool hierarchy and do not inherently provide mechanisms to guarantee memory allocation for specific VMs.
Each standalone host and each DRS cluster has an (invisible) root resource pool that groups the resources of that host or cluster. The root resource pool does not appear because the resources of the host (or cluster) and the root resource pool are always the same.
The resource pools at a higher level are called parent resource pools.
During the staging of a patch on a vCenter Server Appliance, an error was encountered and the process stopped. An administrator resolved the root cause and is ready to continue with the staging of the patch.
From the vCenter Management Interface, which action should the administrator take to continue the process from the point at which the error occurred?
Use the Stage and Install option to resume the staging.
Use the Resume option to resume the staging.
Use the Unstage option to restart the staging.
Use the Stage Only option to restart the staging.
Answer is Use the Resume option to resume the staging.
If vCenter Server encounters a problem staging the patches, the vCenter Server Management Interface displays the Resume button. Correct the problem preventing the patches from staging, and click Resume to finish staging the patches. The staging process resumes from the point at which vCenter Server encountered the problem.
An administrator plans to update the Supervisor cluster and has noticed some of the Tanzu Kubernetes Grid clusters are running an incompatible version.
Which action must the administrator take before proceeding with the Supervisor cluster update?
Update all Tanzu Kubernetes Grid clusters to the latest version prior to the Supervisor cluster update.
No action is needed – Tanzu Kubernetes Grid clusters will be updated automatically as part of the update process.
No action is needed – Incompatible Tanzu Kubernetes Grid clusters can be manually updated after the Supervisor cluster update.
Update incompatible Tanzu Kubernetes Grid clusters prior to the Supervisor cluster update.
Answer is Update incompatible Tanzu Kubernetes Grid clusters prior to the Supervisor cluster update.
You may need to update one or more Tanzu Kubernetes Grid clusters before updating a Supervisor if the Tanzu Kubernetes Grid cluster is not compliant with the target Supervisor version.
An administrator is performing maintenance activities and discovers that a Virtual Machine File System (VMFS) datastore has a lot more used capacity than expected. The datastore contains 10 virtual machines (VMs) and, when the administrator reviews the contents of the associated datastore, discovers that five virtual machines have a snapshot file (-delta.vmdk files) that has not been modified in over 12 months. The administrator checks the Snapshot Manager within the vSphere Client and confirms that there are no snapshots visible.
Which task should the administrator complete on the virtual machines to free up datastore space?
Consolidate the snapshots for each VM.
Inflate the disk files for each VM.
Delete all snapshots for each VM.
Storage vMotion each VM to another datastore.
Answer is Consolidate the snapshots for each VM.
The presence of redundant delta disks can adversely affect the virtual machine performance. You can combine such disks without violating a data dependency. After consolidation, redundant disks are removed, which improves the virtual machine performance and saves storage space.
An administrator has been notified that a number of hosts are not compliant with the company policy for time synchronization.
The relevant portion of the policy states:
All physical servers must synchronize time with an external time source that is accurate to the microsecond.
Which step should the administrator take to ensure compliance with the policy?
Ensure that each vCenter Server Appliance is configured to use a Network Time Protocol (NTP) source.
Ensure that each ESXi host is configured to use a Precision Time Protocol (PTP) source.
Ensure that each ESXi host is configured to use a Network Time Protocol (NTP) source.
Ensure that each vCenter Server Appliance is configured to use a Precision Time Protocol (PTP) source.
Answer is Ensure that each ESXi host is configured to use a Precision Time Protocol (PTP) source.
All physical servers must synchronize time with an external time source that is accurate to the microsecond. NTP is milliseconds. PTP allows for precision within nanoseconds
An administrator is responsible for the management of a VMware vCenter instance that is currently experiencing performance issues. The administrator quickly identifies that the CPU and memory utilization of vCenter is consistently over 80%. Upon further analysis, it seems that the vpxd process is contributing significantly to the performance issue.
A combination of which four steps should the administrator take to resolve the performance issues and ensure that a similar issue can be rectified without requiring downtime to vCenter moving forward? (Choose four.)
Gracefully shut down vCenter using the vSphere Client.
Enable CPU Hot Add on the vCenter virtual machine.
Power on the vCenter Server Appliance using the vSphere Host Client.
Enable CPU and Memory Hot Add on the vCenter virtual machine.
Add additional CPU and memory to the vCenter Server Appliance.
Power on the vCenter Server Appliance using the vSphere Client.
Enable Memory Not Add on the vCenter virtual machine.
Answers are;
A. Gracefully shut down vCenter using the vSphere Client.
C. Power on the vCenter Server Appliance using the vSphere Host Client.
D. Enable CPU and Memory Hot Add on the vCenter virtual machine.
E. Add additional CPU and memory to the vCenter Server Appliance.
You cannot enable hot add while a VM is running, so you must shut it down first. B is wrong, you enable CPU & memory hot add, not just CPU. You add additional resources while it is powered off to increase performance. Lastly you must power it back on with the host client. You cannot power on vCenter with the vSphere client when vCenter is not running
