2V0-21.23 Question 269
Select 3You are configuring a new VMware ESXi host for your organization's data center. The host will be part of a cluster that uses vSphere Distributed Resource Scheduler (DRS) and vSphere High Availability (HA). During the setup process, you need to ensure that the ESXi host is properly configured for network connectivity and can communicate with the cluster services. Which of the following configurations should you apply to the ESXi host?
- A
Assign a static IP address to the ESXi management network.
- B
Enable vSphere HA heartbeat on the ESXi host.
- C
Configure DNS settings, including a valid hostname and primary/secondary DNS servers.
- D
Ensure the ESXi host is part of a vSwitch with sufficient uplinks to handle VM and management traffic.
- E
Install the vSphere Client directly on the ESXi host for management.
Show answer and explanation
Correct answers: A, C, D
Explanation
For an ESXi host to integrate properly into a vSphere cluster, it must have a static IP address for consistent management network communication, correctly configured DNS settings for name resolution, and a network configuration that supports sufficient and redundant uplinks. Other options, such as enabling vSphere HA heartbeat manually or installing the vSphere Client on the ESXi host, are either unnecessary or not technically feasible.
- A. Correct.
Assigning a static IP address to the ESXi management network is required for reliable communication with the cluster and other services such as vCenter Server. DHCP is not recommended in production environments for ESXi management traffic.
- B. Incorrect.
vSphere HA heartbeat is a cluster-level feature and does not need to be manually enabled on individual ESXi hosts. It is automatically configured when the host is added to an HA-enabled cluster.
- C. Correct.
Properly configuring the DNS settings, including hostname and DNS servers, is essential for the ESXi host to communicate with vCenter Server and other infrastructure components.
- D. Correct.
A vSwitch with adequate uplinks is necessary to ensure the ESXi host has sufficient bandwidth for both management and VM traffic, as well as redundancy in case of uplink failure.
- E. Incorrect.
Installing the vSphere Client directly on the ESXi host is not possible. Management of ESXi hosts is performed through the vSphere Web Client or vCenter Server.
