2V0-21.23 Question 176
Select 4An administrator is tasked with troubleshooting a network connectivity issue in a vSphere environment. They suspect a misconfiguration on the vSphere Distributed Switch (vDS). Upon examining the vDS configuration, they notice that several port groups are configured. Which settings should the administrator verify to ensure proper connectivity for virtual machines connected to the distributed port groups?
- A
VLAN ID configuration on distributed port groups
- B
Uplink assignment on the distributed switch
- C
NetFlow configuration on the distributed switch
- D
Security policies such as Promiscuous Mode, MAC Address Changes, and Forged Transmits
- E
Teaming and failover policies for the distributed port groups
Show answer and explanation
Correct answers: A, B, D, E
Explanation
When troubleshooting distributed switch configurations, it is important to verify critical settings such as VLAN IDs, uplink assignments, and security policies to ensure that network traffic is properly routed and not blocked. Additionally, teaming and failover policies play a key role in maintaining connectivity and redundancy. NetFlow configuration, while important for monitoring, does not directly impact connectivity troubleshooting.
- A. Correct.
VLAN ID configuration is critical to ensure that traffic is tagged correctly and routed appropriately across the network.
- B. Correct.
Uplink assignment must be verified to confirm that physical NICs are correctly mapped to the distributed switch to facilitate communication to the external network.
- C. Incorrect.
NetFlow configuration is primarily for traffic monitoring and analysis, not directly related to resolving connectivity issues.
- D. Correct.
Security policies on the distributed port groups must be checked to ensure they are not inadvertently blocking or dropping traffic.
- E. Correct.
Teaming and failover policies determine how traffic is distributed across multiple uplinks and how failover is handled, which is essential for maintaining connectivity.
