VCP-VCF Administrator 2024 Question 101
Select 2You are tasked with scaling a cluster in VMware Cloud Foundation by adding new ESXi hosts. Before performing this task, which prerequisites must be met to ensure a successful cluster scale-out operation?
- A
The new ESXi hosts must be running the same version of the ESXi hypervisor as the existing hosts in the cluster.
- B
The ESXi hosts must be pre-provisioned with the VMware Cloud Foundation management agent (vSphere Agent).
- C
The network configuration of the new hosts must match the existing cluster, including VLANs and IP address ranges.
- D
The desired cluster must have sufficient vSAN disk group resources to accommodate the new hosts.
- E
The new hosts must have identical hardware specifications as the existing hosts in the cluster.
Show answer and explanation
Correct answers: A, C
Explanation
When scaling a cluster in VMware Cloud Foundation, it is critical to ensure that the new ESXi hosts are running the same hypervisor version as the existing cluster and have a matching network configuration (e.g., VLANs, IP ranges). These prerequisites ensure compatibility and proper communication between nodes during the expansion process. Other considerations, such as vSAN disk groups or identical hardware, are managed during or after the scaling operation and are not strict prerequisites.
- A. Correct.
Correct: Consistency in the ESXi version is required to ensure compatibility and avoid operational issues during the scale-out process.
- B. Incorrect.
Incorrect: VMware Cloud Foundation deploys the necessary software components when adding the host to the environment, so this is not a required prerequisite.
- C. Correct.
Correct: The new hosts must have a matching network configuration to ensure they can communicate properly with the existing cluster.
- D. Incorrect.
Incorrect: While vSAN disk group resources are managed during the cluster expansion process, this is not a prerequisite for adding new hosts to the cluster.
- E. Incorrect.
Incorrect: Identical hardware specifications are not mandatory, but the new hosts should meet minimum hardware requirements and be compatible with the existing cluster.
