質問 # 74
A vSAN architect is using the vSAN Sizer to build an All-Flash vSAN cluster for an accounting company. The architect is trying to determine why 12 TBs are set aside for system overhead and is reviewing the items that are include in the overhead capacity.
Which two items are included? (Choose two.)
- A. Host upgrade overhead
- B. Encryption overhead
- C. VM swap overhead
- D. File System overhead
- E. Disk Format overhead
正解：A、E
解説：
According to the VMware vSAN Sizer guide [1], system overhead includes disk format overhead and host upgrade overhead. Disk format overhead is needed to accommodate the additional metadata associated with the vSAN disk format, and host upgrade overhead is needed to support any future host upgrades.

質問 # 75
Which situation could cause a vSAN stretched cluster to fail?
- A. 5ms round-trip lime (RTT) between data sites
- B. Blocked UDP ports on the firewall between data sites
- C. Static routes between the witness site and data sites
- D. Layer 3 communication from the data sites to the witness site
正解：B
解説：
A stretched cluster in vSAN requires a reliable, low latency Layer 3 communication from the data sites to the witness site. Therefore, an interruption of Layer 3 communication from the data sites to the witness site could cause a vSAN stretched cluster to fail. Additionally, blocked UDP ports on the firewall between data sites and high latency (RTT) of more than 5ms between data sites could also cause failure of the vSAN stretched cluster.
質問 # 76
An organization wants to configure a new storage policy based on the following requirements:
Failures to tolerate = FTT 1/RAID-5 (Erasure Coding)
Number of disk stripes per object = 8
IOPS limit for object = 0
Object Space Reservation = Thin provisioning
Flash read cache reservation = 0%
Disable object checksum = No
Force provisioning = No
The administrator creates the policy using storage policy based management and assigns it to a 100GB virtual machine on a 4-node vSAN cluster to test the results of the new storage policy.
How many components will be created per host for the storage objects of the virtual machine on the vSAN datastore?
- A. 0
- B. 1
- C. 2
- D. 3
正解：A
質問 # 77
A vSAN administrator needs to upgrade the vSAN cluster from vSAN 7.0 to 7.0 U1 without disruption. The following steps have been completed in this order:
1. Edited the vLCM image on the current cluster
2. Updated it to vSphere 7.0 U1
3. Changed the vendor addon
4. Selected the firmware bundle from the server vendor
5. Saved the configuration
After saving the configuration, all hosts in the cluster are out of compliance. Which step is needed next to accomplish this task?
- A. Roll back the vLCM configuration to the latest compliant image.
- B. Stage the upgrade images.
- C. Remediate all nodes in the cluster.
- D. Place all hosts in maintenance mode.
正解：A
解説：
Roll back the vLCM configuration to the latest compliant image. After saving the configuration, all hosts in the cluster are out of compliance, so the next step is to roll back the vLCM configuration to the latest compliant image. This can be done by selecting the "Roll Back" option from the vLCM image selection menu. Reference: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.upgrade.doc/GUID-B2F7B3A3-BD7F-4A4F-A77C-90F4B7EAC54F.html
質問 # 78
An application refactor requires significant storage that is being added for logs stored on a VM vDISK. The application VMs runs on a dedicated vSAN enabled vSphere Cluster with custom CPUs and RAM, and therefore, cannot vMotion to another vSAN enabled cluster.
The administrator needs a vSAN feature that can be used to allocate additional storage from another vSAN enabled vSphere cluster to this vSAN enabled Cluster.
Which vSAN feature should be used for this purpose?
- A. vSAN Replication
- B. vSAN File Services
- C. vSAN HCI Mesh
- D. vSAN Stretched Clusters
正解：C
解説：
According to the VMware documentation [1], vSAN HCI Mesh is a feature of vSAN that enables the allocation of storage from one vSAN enabled vSphere cluster to another, allowing for the sharing of resources between clusters. This is particularly useful in scenarios such as the one described, where additional storage needs to be allocated from another vSAN enabled cluster. [1] https://docs.vmware.com/en/VMware-vSphere/7.0/vsphere-esxi-vcenter-server-70-vsan-hci-mesh-guide.pdf
質問 # 79
A customer is running a number of compute-intensive application workloads on their existing 4-node vSAN cluster that has resulted in resource contention. To provide additional compute resources, the vSAN administrator has decided to deploy a new 4-node vSAN compute-only cluster so that a HCI Mesh can be configured.
Which three points would the vSAN administrator need to consider before using this configuration? (Choose three.)
- A. A storage policy of Erasure Coding with FTT=2 would be supported.
- B. The storage policy is based on the total number of hosts across both client and server clusters.
- C. The storage policy must be based on the number of hosts within the server cluster.
- D. A storage policy of Mirroring with FIT 1 would be supported.
- E. The storage policy must be based on the number of hosts within the client cluster.
- F. A storage policy of Erasure Coding with hi 1=1 would be supported.
正解：C、D、F
質問 # 80
Skyline Health vSAN HCL DB up-to-date health check is alerting in red in a newly deployed vCenter Server.

- B. Upgrade the HCL DB from the hardware vendor website.
- C. Upgrade to the latest version of vCenter.
- D. Update the HCL DB online from vmware.com.
- E. Obtain the HCL DB from the hardware vendor, and manually update it.
正解：A、D
質問 # 81
An administrator will be performing a rolling upgrade of a vSAN cluster over the weekend. In preparation, the administrator runs the Data Migration Pre-Check.
Which two items are being checked? (Choose two.)
- A. vSphere HA state
- B. Object compliance and accessibility
- C. DRS settings
- D. Affinity rules
- E. Cluster capacity
正解：B、E
質問 # 82
An vSAN administrator is relying on vSAN Stretched Clusters to protect against entire-site failures. How is this protection accomplished?
- A. By using asynchronous data transfer
- B. By synchronizing virtual machine data from the witness site
- C. By placing redundant components at both sites
- D. By configuring data locality
正解：C
解説：
Each site in the stretched cluster is configured as a fault domain. Fault domains are used to spread redundancy components across servers. In a traditional vSAN cluster, redundant components are spread across servers in separate computing racks, and as a result, can tolerate rack failures, cache and capacity device failures, network device failures, and power failures. When used in a stretched cluster, fault domains spread redundancy components across sites, and therefore can tolerate the failure of an entire data site. The minimum number of hosts in a stretched cluster is three, one host in each data site plus the witness host in the witness site. The maximum number of hosts in a stretched cluster is 31, fifteen hosts in each data site plus the witness host in the witness site.
質問 # 83
vSAN requires that the virtual machines deployed on the vSAN datastores are assigned at least one storage policy, but the administrator did not explicitly assign a storage policy when provisioning the new VM.
What is the result of this situation?
- A. The VM objects will be protected based on the vSAN Default Storage Policy configurations.
- B. The vSphere Web Client will choose the last vSAN Storage Policy used.
- C. The VM provisioning will fail.
- D. No data protection will be applied to the VM objects.
正解：A
解説：
When a virtual machine is deployed on a vSAN datastore, it must be assigned at least one storage policy. If the administrator did not explicitly assign a storage policy when provisioning the new VM, vSAN will apply the vSAN Default Storage Policy to the virtual machine. The vSAN Default Storage Policy is a pre-configured storage policy that is automatically applied to virtual machines when no other storage policy is assigned.
According to VMware's official guide, "If a storage policy is not explicitly assigned to a virtual machine when it is provisioned, the virtual machine objects will be protected based on the vSAN Default Storage Policy configurations." This means that the vSAN Default Storage Policy will apply to the VM objects even if the administrator did not explicitly assign a storage policy when provisioning the new VM.
