VMware vSphere 7.x Professional for Service Providers — Question 49

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

Answer options

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

Correct answer: D, E

Explanation

The correct answers are D and E because the virtual switch does not have visibility into the uplink load, which can lead to overload situations, and a VM with a single MAC address is limited to the throughput of the uplink connected to its port ID. Options A, B, and C are incorrect as they do not directly relate to the disadvantages of the load balancing method based on virtual port ID.
