2V0-21.23 Question 80
Select 2Your organization is planning to deploy a new VMware vSAN cluster. As the vSphere administrator, you are tasked with ensuring the environment meets the basic vSAN requirements. Which of the following prerequisites must be in place before configuring vSAN?
- A
Each host in the cluster must have at least one SSD and one HDD.
- B
A minimum of 10 Gbps networking is required for vSAN traffic.
- C
A minimum of three ESXi hosts is required to form a vSAN cluster.
- D
vSAN storage policies must be configured before enabling vSAN on the cluster.
- E
All participating hosts must have at least one VMkernel adapter configured for vSAN traffic.
Show answer and explanation
Correct answers: C, E
Explanation
To set up a vSAN cluster, certain basic requirements must be met: a minimum of three ESXi hosts is required to ensure data redundancy, and all participating hosts must have a VMkernel adapter configured specifically for vSAN traffic. Other factors, such as networking speed and storage policies, are important for performance and configuration but do not qualify as strict prerequisites for enabling vSAN.
- A. Incorrect.
Incorrect: While each host in a vSAN cluster does require storage devices, vSAN does not require a combination of SSD and HDD. It can operate with all-flash configurations as well.
- B. Incorrect.
Incorrect: While 10 Gbps networking is recommended for performance in certain scenarios, vSAN only requires a minimum of 1 Gbps networking for hybrid configurations and 10 Gbps for all-flash configurations. This is not a strict prerequisite.
- C. Correct.
Correct: A minimum of three ESXi hosts is required to form a vSAN cluster to maintain data availability and redundancy.
- D. Incorrect.
Incorrect: While vSAN storage policies are used to define how data is stored and protected, they are not a prerequisite for enabling vSAN itself.
- E. Correct.
Correct: All hosts participating in the vSAN cluster must have at least one VMkernel adapter configured for vSAN traffic to ensure proper communication and data replication between hosts.
