VMware vSphere 7.x Delta — Question 53

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

Option A is correct because a VM can only utilize the bandwidth of the specific uplink tied to its port ID. Option C is also correct, as the virtual switch lacks awareness of the load on uplinks, possibly leading to some uplinks being overloaded. The other options either misrepresent how load balancing works or describe features that do not directly relate to the disadvantages of this configuration.
