2V0-21.23 Question 71
Single answerA VMware administrator is managing a vSphere environment where multiple traffic types such as vMotion, iSCSI storage, and management traffic share the same physical network. To ensure that business-critical traffic like iSCSI storage has guaranteed bandwidth during network congestion, the administrator decides to implement Network I/O Control (NIOC). What feature of NIOC should the administrator configure to meet this requirement?
- A
Network Resource Pools
- B
Traffic Shaping Policies
- C
Network IO Shares
- D
Physical NIC Teaming
Show answer and explanation
Correct answer: C
Explanation
Network I/O Control (NIOC) allows administrators to manage and prioritize network traffic in a vSphere environment. By configuring Network IO Shares, the administrator can allocate bandwidth shares to specific traffic types, ensuring that critical traffic like iSCSI storage is prioritized during network congestion. This feature is essential for maintaining performance and reliability in environments with multiple competing traffic types.
- A. Incorrect.
Network Resource Pools are used to group traffic types, but they do not directly manage bandwidth allocation during congestion. This is not the correct feature to configure for guaranteeing bandwidth.
- B. Incorrect.
Traffic Shaping Policies are used to limit the outbound traffic on a virtual network adapter, but they do not prioritize or guarantee bandwidth during congestion.
- C. Correct.
Network IO Shares allow the administrator to allocate relative priority and bandwidth shares to different traffic types. This is the correct feature to ensure that iSCSI storage traffic has guaranteed bandwidth during congestion.
- D. Incorrect.
Physical NIC Teaming provides redundancy and load balancing for network traffic but does not guarantee bandwidth for specific traffic types during congestion.
