VCP-VCF Administrator 2024 Question 185
Single answerAn administrator is configuring a new Virtual Distributed Switch (vDS) in a VMware Cloud Foundation environment to support multiple workloads. The administrator needs to ensure that the switch provides consistent network configuration across all connected ESXi hosts and supports features such as port mirroring and Network I/O Control (NIOC). Which initial step is required to configure the Virtual Distributed Switch correctly?
- A
Add ESXi hosts to the vDS and assign physical NICs to uplink ports.
- B
Create distributed port groups for virtual machine traffic.
- C
Assign VLAN IDs to the port groups.
- D
Create a new Virtual Distributed Switch and define the number of uplinks.
Show answer and explanation
Correct answer: D
Explanation
The first step in configuring a Virtual Distributed Switch (vDS) is to create the vDS itself and define the number of uplinks. This step establishes the logical switch infrastructure, upon which additional components like distributed port groups, VLAN IDs, and host connections can be configured. Without creating the vDS, other configuration steps cannot proceed.
- A. Incorrect.
Adding ESXi hosts and assigning physical NICs to uplink ports is a necessary step, but it comes after creating the vDS. The vDS must first be created to allow hosts and NICs to be added.
- B. Incorrect.
Creating distributed port groups happens after the vDS is created. Port groups define the logical network segmentation, but they cannot be created before the vDS exists.
- C. Incorrect.
Assigning VLAN IDs to the port groups is required for network segmentation, but this step is part of distributed port group configuration, which is done after the vDS is created.
- D. Correct.
Creating a new Virtual Distributed Switch and defining the number of uplinks is the first step in the configuration process. This creates the foundation for all subsequent configurations, such as adding hosts, NICs, and port groups.
