2V0-21.23 Question 56
Select 3A company is planning to manage a large vSphere environment with hundreds of ESXi hosts and thousands of virtual machines. The IT administrator is considering whether to use VMware Standard Switches (VSS) or VMware Distributed Switches (VDS). Which of the following features and benefits of VDS would make it the preferred choice in this scenario?
- A
Centralized management and configuration for all ESXi hosts in the cluster
- B
Support for advanced networking features like Network I/O Control (NIOC) and port mirroring
- C
Ability to configure networking on individual ESXi hosts without dependency on vCenter Server
- D
Simplified troubleshooting with tools such as NetFlow and port mirroring
- E
Requires fewer resources to set up and manage compared to VMware Standard Switches
Show answer and explanation
Correct answers: A, B, D
Explanation
VMware Distributed Switches (VDS) are ideal for large vSphere environments with multiple hosts and virtual machines as they provide centralized management, advanced networking features, and robust troubleshooting tools. These capabilities are crucial for maintaining consistency, optimizing network performance, and efficiently diagnosing issues in complex, large-scale environments. While VDS does require vCenter Server and more resources compared to VMware Standard Switches (VSS), its benefits outweigh these considerations in such scenarios.
- A. Correct.
Correct: VMware Distributed Switches (VDS) provide centralized management, making it easier to manage networking across multiple ESXi hosts in a large environment.
- B. Correct.
Correct: VDS supports advanced networking features such as Network I/O Control (NIOC) and port mirroring, which are particularly beneficial in large-scale environments.
- C. Incorrect.
Incorrect: VMware Standard Switches (VSS), not VDS, allow networking configurations on individual ESXi hosts without dependency on vCenter Server. VDS requires vCenter Server for centralized management.
- D. Correct.
Correct: VMware Distributed Switches include enhanced troubleshooting tools like NetFlow and port mirroring, which simplify network diagnostics in complex setups.
- E. Incorrect.
Incorrect: VDS typically requires more resources and planning compared to VSS due to its advanced features and centralized management capabilities.
