Question 3
A company has engaged a consultant to upgrade an existing vSAN cluster to vSAN 7.0 U1. The company wants to ensure that the same vSAN process can be used in the future.
During the discovery phase, the consultant found the following information about the existing environment:
* The vCenter Server is currently version 7.0.
* The vSAN Cluster has the following configuration:
- vSAN version: 7.0
- Number of vSAN nodes: 6
- Encryption: enabled
- Deduplication and Compression: enabled
- Fault Domains: 1
- vSAN Capacity Utilization: 60%
* Each vSAN node has the following configuration:
- ESXi version: VMware vSphere 7.0
- CPU: 2 processors, 20 cores
- RAM: 1024GB RAM.
- Disk: 2 Cache SSDs and 6 Capacity SSDs
- Network: 4 x 10GbE
* All current hardware (which is from a single vendor) is listed on the vSAN Compatibility Guide for vSAN 7.
Which three recommendations should the consultant make to ensure that the vSAN cluster upgrade is completed? (Choose three.)

Question 7
As a part of a network hardware refresh project, all the network switches have been replaced with a newer, high-performance model. After the replacement, the company users started experiencing slowness on the applications hosted on their vSAN-backed VMs.
The vSAN administrator checked the vSAN Network Health status and noticed that the "Hosts large ping test" has failed.
What could be the cause of this performance degradation issue?
