NEW QUESTION # 26
Which description is a valid use case for an administrator to configure an HCI Mesh?
- A. Share storage hosted by or on a vSAN cluster to more than 64 hosts, including both local and remote hosts connected.
- B. Share storage hosted by or on a vSAN cluster that must be applied to different vSAN SPBM policies for different client clusters.

NEW QUESTION # 27
In a vSAN stretched cluster, which value must be set in the vSAN policy if there is no requirement for data mirroring across sites?
- A. SFTT = 0
- B. SFTT = 1
- C. PFTT = 0
- D. PFTT = 1
Answer: C
Explanation:
Primary level of failures to tolerate (PFTT). For stretched clusters, PFTT defines the number of site failures that a virtual machine object can tolerate. For a stretched cluster, only a value of 0 or
1 is supported.
Secondary level of failures to tolerate (SFTT). For stretched clusters, SFTT defines the number of additional host failures that the object can tolerate after the number of site failures defined by PFTT is reached. If PFTT = 1 and SFTT = 2, and one site is unavailable, then the cluster can tolerate two additional host failures.
The default value is 0, and the maximum value is 3.
So data mirroring across sites = PFTT

NEW QUESTION # 36
An 8-Node vSAN Stretched Cluster (4+4+1) with a single disk group has a policy with PFTT=1 (mirrored across sites) and SFTT=1/FTM Mirroring (Local Protection) configured. The administrator has been alerted that there is a problem with the cluster. The following has been observed:
* The vSAN Witness Host is offline.
* Two disk failures on two hosts have occurred in the preferred site.
This has resulted in a critical production virtual machine's vmdk becoming inaccessible. Which step needs to be performed by the administrator to resolve the issue?
- A. Replace only one failed disk on the preferred site.
- B. Replace access to the existing vSAN Witness Host
- C. Replace the vSAN Witness Host
- D. Replace all failed disks on the preferred site.
Answer: B
Explanation:
