2V0-21.23 Question 153
Select 3An organization is planning to migrate its legacy data center to a VMware vSphere environment. The design team needs to ensure high availability (HA) for critical applications and plans to deploy a cluster with vSphere HA enabled. During the planning phase, the team must consider multiple factors to properly configure HA in their environment. Which factors must be considered during the design of the HA cluster?
- A
Admission control policies to reserve resources for failover
- B
The number of datastores connected to the hosts in the cluster
- C
The network configuration and redundancy for the management network
- D
The number of virtual machines and their resource reservations
- E
The type of storage (e.g., NFS, iSCSI, or vSAN) used for virtual machine files
Show answer and explanation
Correct answers: A, C, D
Explanation
When designing a vSphere HA cluster, it is essential to consider factors that directly impact the availability and reliability of the cluster. Admission control policies ensure resources are reserved for failover, while proper network configuration and redundancy for the management network ensure that HA features can function correctly. Additionally, the number of virtual machines and their resource reservations must be accounted for to ensure there is sufficient capacity to handle failover events. While storage design is important overall, factors like the number of datastores or storage type are not directly related to HA cluster design.
- A. Correct.
Correct: Admission control policies are critical for ensuring that sufficient resources are reserved for failover scenarios, which is a key consideration in vSphere HA design.
- B. Incorrect.
Incorrect: While the number of datastores is important for storage design, it is not specifically a factor in configuring or designing a vSphere HA cluster.
- C. Correct.
Correct: The management network is fundamental to vSphere HA since it is used for communication between hosts. Proper network redundancy ensures that HA features work reliably.
- D. Correct.
Correct: The number of virtual machines and their resource reservations directly impact HA design as they determine the required capacity for failover and cluster configuration.
- E. Incorrect.
Incorrect: Although the type of storage affects overall environment design, it does not directly influence the configuration of a vSphere HA cluster.
