Question 45

During a vSAN design workshop, the infrastructure team highlighted the need to ensure the availability and resiliency of the vSAN network for their production clusters. Each ESXi host is connected to the TOR switches with two 1 GB physical adapters. The physical network fabric is using a spine-leaf architecture.
These subnets are available for the ESXi hosts:
•	Subnet A: 192.168.10.0/24
•	Subnet B: 192.168.20.0/24
Which three strategies can the architect suggest to satisfy these customer requirements? (Choose three.)

A. Configure MTU 9K jumbo frame on the hosts and leaf switches.

B. Configure NIC teaming.

C. Replace the server NICs with 10 GB ones.

D. Add one vSAN VMKernel port to subnet B.

E. Add one vSAN VMKernel port to subnet A.

F. Add two vSAN VMKernel ports to subnet A.

Question 46

An architect is currently working with a customer to transform their existing ESXi hosts to vSAN nodes. The customer expressed the following requirements.
•	First phase will transform 50% of the hosts to a hybrid vSAN nodes.
•	Second phase will transform the remaining 50% hosts to an All-Flash vSAN nodes.
The following constraint exists:
•	Each host has a 4-port x 1 GbE network interface.
Which two recommendations should the architect make to align with the customer's requirements? (Choose two.)

A. Hybrid vSAN clusters can have shared 1 GbE network adapters.

B. All-Flash vSAN clusters must have dedicated 10 GbE network adapters.

C. Hybrid vSAN clusters must have dedicated 1 GbE network adapters.

D. All-Flash vSAN clusters can have shared 10 GbE network adapters.

E. Hybrid vSAN clusters must have dedicated 10 GbE network adapters.

Question 47

An administrator has decided to switch the Preferred Fault Domain in a vSAN stretched cluster. Resynchronization activity increased drastically after this change.
Which action should the administrator take next time to avoid this problem?

A. Changing the Data locality setting to None

B. Adding additional hosts to both domains in existing vSAN cluster

C. Adding disks to hosts and creating additional disk groups

D. Putting all hosts from Secondary domain into maintenance mode

Question 48

A company hosts a vSAN 7 stretched cluster for all development workloads. The original sizing of a maximum of 250 concurrent workloads in the vSAN cluster is no longer sufficient and needs to increase to at least 500 concurrent workloads within the next six months.
To meet this demand, the original 8-node (4-4-1) cluster has recently been expanded to 16 nodes (8-8-1).
Which three additional steps should the administrator take to support the current growth plans while minimizing the amount of resources required at the witness site? (Choose three.)

A. Add the new vSAN witness appliance to vCenter Server.

B. Deploy a new large vSAN witness appliance at the witness site.

C. Configure the vSAN stretched cluster to use the new vSAN witness.

D. Deploy a new extra large vSAN witness appliance at the witness site.

E. Upgrade the vSAN stretched cluster to vSAN 7.0 U1.

F. Configure the new vSAN witness as a shared witness appliance.

Question 49

An administrator would like to upgrade ten identically configured 2-node vSAN clusters from vSAN 6.7 U3 to vSAN 7.0 U1. Currently, each 2-node vSAN cluster is using a dedicated vSAN witness host appliance. As a result of the upgrade, the administrator would like to leverage the vSAN shared witness feature to reduce the resources being consumed.
In preparation for the first vSAN cluster upgrade, the administrator has completed the following tasks:
1. Upgraded vCenter Server to vCenter Server 7.0 U1.
2. vSphere High Availability (HA) has been disabled on the vSAN Cluster.
3. Upgraded the vSAN witness host appliance to vSphere 7.0 U1.
4. Upgraded both vSAN data nodes to vSphere 7.0 U1.
The key requirement is to ensure that backwards compatibility to the existing version of vSAN is maintained during the upgrade process.
Which three additional steps should the administrator complete to ensure that subsequent clusters can share the same vSAN Witness? (Choose three.)

A. Upgrade the vSAN On-Disk Format (ODF) to version 12.

B. Manually update the vSAN Witness with a vSAN 7 license key.

C. Update the vSAN cluster to use the new vSAN witness host appliance.

D. Configure the existing witness host appliance to act as a shared witness.

E. Deploy a new vSAN 7.0 U1 witness host appliance to act as a shared witness.

F. Upgrade the vSAN On-Disk Format (ODF) to version 13.
