NEW QUESTION # 46
An administrator has a 4-node vSAN cluster, and all virtual machine storage policies are configured as RAID-1 FTT-1. The administrator puts Host-1 in maintenance mode using "Ensure Accessibility".
During this time, Host-2, which is holding the updated object replica, fails permanently. A few moments later, Host-1 exits maintenance mode.
What happens to the writes that were committed on Host-2 after Host-1 enters this mode?
- A. Any writes to Host-2 that occurred after Host-1 entered maintenance mode are lost.
- B. The latest writes are retrieved from backups.
- C. The latest writes were also written on a third host and are applied to the stale components of Host-1 once the host exits maintenance mode.
- D. The latest writes from Host-2 are applied to the stale components of Host-1 once the host exits maintenance mode.
Answer: D
Explanation:
This is because vSAN maintains a copy of the object on each host that is a member of the vSAN cluster. When a host enters maintenance mode, the object's replica is moved to another host in the cluster. If another host in the cluster fails during this time, it's possible that the updated replica of an object may be lost. However, vSAN will still use the stale replica of the object on the host that exited maintenance mode to service read requests, and will update the stale replica with the latest writes from the remaining host after the host exits maintenance mode.
It is important to note that this scenario assumes that the host failure is a permanent failure and that vSAN does not have any additional data protection methods enabled such as RAID-5, RAID-6, or Erasure Coding.
The correct answer is D. The latest writes from Host-2 are applied to the stale components of Host-1 once the host exits maintenance mode. This is because vSAN utilizes a "write-order fidelity" mechanism which ensures that any writes that were committed to the other hosts in the cluster before Host-1 entered maintenance mode are applied to the stale components of Host-1 as soon as the host exits maintenance mode.

NEW QUESTION # 47
A vSAN administrator has been provided hardware to create the vSAN infrastructure. AH six SSD devices per host are on the VMware HCL. The administrator wants to use the disk group configuration that would maximize the amount of vSAN cache available and help provide better storage performance for the new development workloads.
Which disk group configuration should be used?
- A. 6 disk groups with 1 disk in each disk group configuration
- B. A single disk group with 6 disks in the configuration
- C. 2 disk groups with 3 disks in each disk group configuration
- D. 3 disk groups with 2 disks in each disk group configuration
Answer: D
Explanation:
According to the VMware official documentation, this is the recommended disk group configuration for maximizing the amount of vSAN cache available and providing better storage performance for development workloads. This configuration allows for more capacity and flash devices to be used, increasing the amount of available cache and providing more storage options. Additionally, this configuration allows for more flexibility in the sizing of the capacity tier, allowing the administrator to adjust the size of the capacity tier to best suit the needs of the workloads.
NEW QUESTION # 48

- B. Trigger a manual resync, and allow vSAN to heal the object.
- C. Identity and remove the obsolete object.
- D. Restart the host, and obsolete objects will be removed on their own.
Answer: C
NEW QUESTION # 49
A vSAN administrator has a vSAN cluster that is using vSphere Lifecycle Manager (vLCM) to manage hypervisor, server drivers, and firmware. All hosts in the cluster are compliant according to the vLCM image.
A 10GB NIC on the servers is experiencing issues, the vSAN administrator determines a new network driver will resolve the problem. Unfortunately, the required NIC driver is a newer version compared to the driver provided by the most recent Vendor Addon.
Which action should the vSAN administrator take to ensure the latest network driver is installed on the NIC before remediation?
- A. Remove the Vendor Addon from the vLCM image, and then manually install the network driver on the servers.
- B. Add an individual component to the vLCM image that has the updated NIC driver.
- C. Since server vendors release periodic server Vendor Addon updates, make sure the vLCM image is configured to use the most recent version of the vendor addon.
- D. Modify the vLCM image to omit the NIC Driver, and then manually update the servers with the required NIC driver.
Answer: B

NEW QUESTION # 52
An administrator has deployed a development VMware vSAN 7.0 U1 cluster. It will be used by the development teams to deploy a mixture of cloud-native stateful applications alongside a combination virtual machine and Kubernetes workloads.
Which vSAN feature should be configured for the vSAN Data Persistence platform (vDPp)?

NEW QUESTION # 53
An administrator wishes to prevent vCenter notifications of vSAN Health status during a scheduled maintenance window.
Which action can be taken to achieve this goal?
- A. Disable the performance service.
- B. Silence the alert from the HTML client.
- C. Disable SNMP service.
- D. Run performance diagnostics prior to scheduled maintenance.
Answer: B
Explanation:
You can silence the vSAN health status alerts from the vCenter HTML client. This will prevent vCenter from sending notifications during the scheduled maintenance window. To silence an alert, you can navigate to the "Monitoring" tab, go to "Alarms" and click on the desired alert to open its settings. From there, you can select "Actions" and then "Silence Alarm". This will prevent notifications for the selected alert until it is cleared or unsilenced.
Please note that this is not a permanent solution and will need to be reapplied after maintenance if desired. Reference: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.monitoring.doc/GUID-E5D5F4A4-2F5C-4F6E-9E97-8CBB3D3F3E6B.html

Which strategy should be used to achieve this goal?
- A. Perform a complete update, omitting the on-disk format update.
- B. Select the *No data migration" maintenance mode option.

Answer: B,E
NEW QUESTION # 56
A vSAN administrator is tasked with changing the stripe width for a specific storage policy on a vSAN 7.0 GA cluster in order to improve performance, but the component distribution desired is across hosts, not just across a disk group.
