VCP-VCF Administrator 2024 Question 318
Select 2You are tasked with placing a host in a VMware Cloud Foundation workload domain into maintenance mode. Which of the following steps should you perform to ensure a successful transition while maintaining system availability and compliance with best practices?
- A
Verify that the host is not running any critical workloads before initiating maintenance mode.
- B
Migrate any running virtual machines to other hosts within the cluster using vSphere vMotion.
- C
Manually shut down all VMs on the host before putting the host into maintenance mode.
- D
Ensure that the host is part of a cluster with Distributed Resource Scheduler (DRS) enabled.
- E
Place the host into maintenance mode directly from the VMware Cloud Foundation SDDC Manager interface.
Show answer and explanation
Correct answers: B, D
Explanation
To set a host into maintenance mode in VMware Cloud Foundation, it is essential to ensure system availability and follow best practices. Migrating workloads using vSphere vMotion prevents downtime, and having DRS enabled allows for seamless automatic migrations. Other options, such as manually shutting down VMs or using the SDDC Manager, are not aligned with the correct procedure or best practices for this task.
- A. Incorrect.
Verifying that the host is not running critical workloads is unnecessary because vSphere tools, like vMotion, automatically handle VM migrations to ensure critical workloads are not disrupted.
- B. Correct.
Migrating the virtual machines using vSphere vMotion is the correct step to ensure that workloads are moved to other hosts without causing downtime.
- C. Incorrect.
Manually shutting down all VMs on the host is not required as maintenance mode is designed to handle VM migrations automatically if the necessary configurations, such as vMotion, are in place.
- D. Correct.
Ensuring that the host is part of a cluster with Distributed Resource Scheduler (DRS) enabled is a best practice because DRS facilitates the automatic migration of VMs when a host enters maintenance mode, reducing administrative overhead.
- E. Incorrect.
Placing the host into maintenance mode directly from the VMware Cloud Foundation SDDC Manager interface is not the correct procedure. This action should be performed through the vSphere Client or vCenter interface managing the host.
