2V0-21.23 Question 79
Select 3An administrator is planning to deploy a vSAN cluster for their data center. The cluster will consist of 5 ESXi hosts and needs to support hybrid configuration. Which of the following requirements must be met to successfully configure the vSAN cluster?
- A
Each host must have at least one SSD for the cache tier in a hybrid configuration.
- B
Each host must contribute at least one HDD to the capacity tier in a hybrid configuration.
- C
All hosts must have a minimum of 25 Gbps network adapters for vSAN traffic.
- D
vSAN requires a minimum of 3 ESXi hosts to form a cluster.
- E
Each host must have RAID controllers set to RAID 5 mode for vSAN compatibility.
Show answer and explanation
Correct answers: A, B, D
Explanation
To configure a vSAN cluster in a hybrid configuration, each ESXi host must contribute at least one SSD for the cache tier and at least one HDD for the capacity tier. A minimum of 3 ESXi hosts is required to meet vSAN's redundancy and availability requirements. While a high-speed network is recommended, vSAN can operate with a minimum of 1 Gbps. RAID levels are not required as vSAN uses software-based redundancy mechanisms.
- A. Correct.
Correct: In a hybrid configuration, each host must provide at least one SSD for the cache tier to accelerate reads and writes.
- B. Correct.
Correct: In a hybrid configuration, at least one HDD per host is required for the capacity tier to store data.
- C. Incorrect.
Incorrect: While a high-speed network is recommended, vSAN only requires a minimum of 1 Gbps for hybrid configurations, though 10 Gbps is strongly recommended.
- D. Correct.
Correct: A minimum of 3 ESXi hosts is required for vSAN to ensure storage redundancy and availability.
- E. Incorrect.
Incorrect: vSAN does not require RAID controllers to be set to RAID 5. It uses software-defined storage and handles redundancy and fault tolerance natively.
