2V0-21.23 Question 177
Single answerAn administrator is configuring a Virtual Standard Switch (VSS) for a vSphere environment. They need to ensure that specific virtual machines (VMs) on the network can only use predefined bandwidth limits and that outgoing network traffic is shaped. Which advanced virtual networking option should the administrator configure?
- A
Traffic Shaping
- B
Promiscuous Mode
- C
Port Mirroring
- D
NIC Teaming
Show answer and explanation
Correct answer: A
Explanation
To configure bandwidth limits and shape outgoing network traffic on a VSS, the Traffic Shaping option must be used. This feature enables administrators to define average bandwidth, peak bandwidth, and burst size for outgoing traffic on a port group or virtual switch, ensuring adherence to predefined network policies. Other options, such as Promiscuous Mode, Port Mirroring, or NIC Teaming, do not provide the functionality required in this scenario.
- A. Correct.
Traffic Shaping is a feature of VSS that allows administrators to control the bandwidth of outgoing traffic, ensuring compliance with network policies and preventing bandwidth abuse. This is the correct option in this scenario.
- B. Incorrect.
Promiscuous Mode allows a virtual machine to see all network traffic passing through the switch, regardless of destination. This does not apply to bandwidth control or traffic shaping.
- C. Incorrect.
Port Mirroring is used to send a copy of network packets from one port to another for monitoring or analysis. This is unrelated to setting bandwidth limits or shaping outgoing traffic.
- D. Incorrect.
NIC Teaming is used to aggregate multiple physical NICs for redundancy or load balancing. While beneficial for network performance and resilience, it does not address bandwidth limiting or traffic shaping.
