A vSAN administrator needs to update vSAN from version 7.0.2 to version 8.0. Which is the correct order to perform the update?
Correct Answer:C
The correct order to perform the update from vSAN version 7.0.2 to version 8.0 is to upgrade the vCenter Server first, then upgrade the ESXi hosts, and finally upgrade the vSAN on-disk format. This order follows the general vSphere upgrade order, which ensures compatibility and interoperability between different components. Upgrading the vCenter Server first allows it to manage and monitor the ESXi hosts and the vSAN cluster during the upgrade process. Upgrading the ESXi hosts second ensures that they have the latest software patches and drivers for vSAN. Upgrading the vSAN on-disk format last enables the new features and functionality of vSAN 8.0. The other options are not correct, as they do not follow the recommended upgrade order.
An administrator is responsible for managing a five-node vSAN cluster. The vSAN Cluster is configured with both vSphere High Availability (HA) and vSphere Distributed Resource Scheduler (DRS). The vSAN Cluster is currently hosting 150 virtual machines that have consumed 60% of the usable capacity.
Each virtual machine belongs to one of the following vSAN Storage Policies: vSANPolicy1:
Site Disaster Tolerance: None
Failures to Tolerate: 1 failure - RAID-5 (Erasure Coding) vSANPolicy2:
Site Disaster Tolerance: None
Failures to Tolerate: No data redundancy
Following an unplanned power event within the data center, the administrator has been alerted to the fact that one host has permanently failed.
What will be the impact to any virtual machine that was running on the failed host using
vSANPolicy1?
Correct Answer:A
The impact to any virtual machine that was running on the failed host using vSANPolicy1 is that each virtual machine will be restarted on another vSAN host using vSphere HA. This is because vSANPolicy1 has a Failures to Tolerate setting of 1 failure - RAID-5 (Erasure Coding), which means that each object has four components (three data and one parity) distributed across four hosts. If one host fails, the object can still be accessed with the remaining three components,and vSphere HA will restart the virtual machine on another host. vSAN will also try to rebuild the missing component on another host, if there is enough capacity and resources. The other options are incorrect because they either assume that the object is unavailable or that the recovery process is delayed or impossible.

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, and 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 Add-on.
Which action should the vSAN administrator take to ensure the latest network driver is installed on the NIC before remediation?
Correct Answer:B
To ensure the latest network driver is installed on the NIC before remediation, the vSAN administrator should add an individual component to the vLCM image that has the updated NIC driver. This action allows the administrator to override the driver provided by the vendor add-on and use a newer version that is compatible with the ESXi version and the hardware device. The administrator can add an individual component to the vLCM image by importing it from a ZIP file or selecting it from the vLCM depot. The other options are not correct. Making sure the vLCM image is configured to use the most recent version of the vendor add-on will not help, as the required NIC driver is a newer version than the one provided by the vendor add-on. Removing the vendor add-on from the vLCM image or modifying the vLCM image to omit the NIC driver will not ensure the latest network driver is installed on the NIC, as these actions will leave the NIC without any driver update. Manually installing or updating the network driver on the servers is not recommended, as it might cause inconsistency and non-compliance in the vLCM image.
