VCP-VMC 2024 Question 169
Select 3A VMware administrator has been tasked with expanding an existing vSphere cluster to handle increased workload demand. The cluster currently has three hosts, and the administrator plans to add two additional hosts. Before adding the hosts, the administrator needs to ensure that the cluster is properly configured to support the new hosts and workloads. Which actions should the administrator take to complete this cluster operation successfully?
- A
Ensure the new hosts have the same network configuration and access to shared storage as the existing hosts.
- B
Disable DRS and HA on the cluster to avoid any interruptions during the addition of new hosts.
- C
Verify that the CPU and memory resources of the new hosts match or are compatible with the existing hosts in the cluster.
- D
Ensure the new hosts are licensed and running the same version of ESXi as the existing hosts.
- E
Enable Maintenance Mode on the existing hosts to ensure they are not impacted during the addition of new hosts.
Show answer and explanation
Correct answers: A, C, D
Explanation
When expanding a VMware cluster, it is important to ensure that the new hosts are compatible with the existing cluster in terms of network configuration, shared storage access, CPU and memory compatibility, licensing, and ESXi version. These steps ensure that the new hosts can seamlessly integrate into the cluster and support workloads effectively. Disabling DRS and HA or enabling Maintenance Mode on existing hosts are not necessary and could impede cluster operations.
- A. Correct.
Ensuring consistent network configuration and shared storage access between the new and existing hosts is critical for smooth integration and workload mobility.
- B. Incorrect.
Disabling DRS and HA is not recommended. These features can help manage workloads and ensure high availability even during the addition of new hosts.
- C. Correct.
CPU and memory compatibility are essential to maintaining cluster uniformity and avoiding issues with vMotion and workload balancing.
- D. Correct.
Licensing and ESXi version uniformity are required to ensure the new hosts can participate in the cluster without compatibility issues.
- E. Incorrect.
Enabling Maintenance Mode on existing hosts is unnecessary when adding new hosts. Maintenance Mode is typically used when performing updates or maintenance on specific hosts.
