2V0-21.23 Question 57
Single answerA company is deploying a virtualized infrastructure and needs to configure networking for their ESXi hosts. They want to ensure consistent network configuration across all hosts, minimize manual configuration, and centralize management. Additionally, they require the ability to apply advanced network policies such as port mirroring and NetFlow monitoring. Based on these requirements, which type of VMware switch should they use?
- A
VMware Standard Switch (VSS)
- B
VMware Distributed Switch (VDS)
- C
Physical Network Switch
- D
NSX-T Logical Switch
Show answer and explanation
Correct answer: B
Explanation
To meet the company’s requirements for consistent network configuration, centralized management, and advanced networking features, the VMware Distributed Switch (VDS) is the correct choice. Unlike VMware Standard Switch (VSS), the VDS enables centralized control and configuration at the vCenter level, reducing manual effort and ensuring uniformity across all ESXi hosts. Additionally, VDS supports advanced features like port mirroring and NetFlow monitoring, which are not available in VSS.
- A. Incorrect.
VMware Standard Switch (VSS) is a per-host switch, which requires manual configuration on each ESXi host. It does not support centralized management or advanced features like port mirroring or NetFlow.
- B. Correct.
VMware Distributed Switch (VDS) is managed at the vCenter Server level, providing consistent configuration across hosts, centralized management, and support for advanced features such as port mirroring and NetFlow monitoring, which meet the company's requirements.
- C. Incorrect.
Physical Network Switch operates outside of the VMware environment and does not provide the virtualization-specific features or centralized management required for the company’s virtualized infrastructure.
- D. Incorrect.
NSX-T Logical Switch is used in VMware NSX environments for software-defined networking (SDN) but is not directly applicable for managing physical NICs or centralizing host-level switch configurations in this scenario.
