2V0-21.23 Question 169
Single answerAn administrator is tasked with creating a new distributed switch in a vSphere environment. The environment consists of multiple ESXi hosts managed by a vCenter Server. The administrator wants to ensure that the distributed switch is created with proper uplink configuration to support redundancy. Which step is required during the creation of the distributed switch?
- A
Specify the number of uplink ports for the distributed switch.
- B
Configure VLANs for all virtual machine port groups.
- C
Assign physical NICs to the distributed switch uplinks.
- D
Enable Network I/O Control (NIOC) on the distributed switch.
Show answer and explanation
Correct answer: A
Explanation
When creating a distributed switch in vSphere, specifying the number of uplink ports is a required step. This determines how many physical NICs from the ESXi hosts can be assigned to the switch for redundancy and scalability. The other options, while important for distributed switch operation, are either optional or performed after the switch is created.
- A. Correct.
This is required during the creation of a distributed switch to define how many uplink ports will be available for physical NICs to connect to the switch.
- B. Incorrect.
While configuring VLANs is necessary for network traffic segmentation, it is not a required step during the initial creation of the distributed switch.
- C. Incorrect.
Assigning physical NICs to the distributed switch is done after the switch is created and is not part of the creation process itself.
- D. Incorrect.
Enabling Network I/O Control (NIOC) is an optional step that can be done after the distributed switch is created. It is not a required step during the creation process.
