VMware vSphere 7.x Professional (VCP-DCV 2021) — Question 98

A VSS is configured with two uplinks and assigned a load balancing policy route based on a virtual port ID.
What are two potential disadvantages of this configuration? (Choose two.)

Answer options

• A. A VM with a single MAC address is limited to the speed of the uplink associated with the relevant port ID.
• B. Higher resource consumption compared to other load balancing algorithms will occur.
• C. The virtual switch is unaware of uplink load and uplinks might become overloaded.
• D. The NIC with less load is more likely to be chosen if port IDs match.
• E. ESXi will use NIOC to attempt to mitigate network congestion when an uplink becomes saturated.

Correct answer: A, C

Explanation

The correct answer A indicates that a VM's bandwidth is confined to the uplink associated with its port ID, which restricts performance. Answer C is also correct because the virtual switch lacks awareness of the uplink load, risking overload on specific uplinks. The other options do not accurately reflect the issues associated with this specific load balancing configuration.
